     DETAILED DESCRIPTION 
     The present invention, in some embodiments thereof, relates to broadcasting and detecting availability of updated data at wireless devices, and, more specifically, but not exclusively, to broadcasting and detecting availability of updated data at wireless devices according to data broadcasted before establishing a connection between the wireless devices. 
     According to some embodiments of the present invention, there are provided methods, devices and computer program products for indicating availability of data at wireless devices and transferring the data to mobile devices via one or more wireless channels, in particular, limited (short) range wireless channels, for example, Bluetooth, Bluetooth Low Energy (BLE), ZigBee, Z-Wave, Wireless Local Area Network (WLAN, e.g. Wi-Fi) and/or the like. 
     One or more wireless devices may be configured to collect data, for example, sensory data captured by one or more sensors, for example, pressure data, proximity data, imagery data, audible data and/or the like. One or more mobile devices, for example, a Smartphone, a smart watch, a wearable device, a carry-able device and/or the like typically associated with users may communicate with one or more of the wireless devices to receive the data collected by the wireless device(s). 
     Each wireless device capable of connecting and communicating via the wireless channel(s) may typically identify itself by broadcasting a device identifier as defined by one or more communication protocols applicable for the wireless channel(s). The device identifier may typically include a fixed part to uniquely and deterministically identify the wireless device, for example, a Media Access Controller (MAC) address, an Internet Protocol (IP) address and/or the like. However, the device identifier may further include an adjustable part which may be dynamically adjusted and/or changed, for example, a device name, a device status and/or the like. 
     One or more of the wireless devices may be therefore configured to publish availability of collected data available at the respective wireless device by adjusting the adjustable part of their device identifier. Specifically, the wireless device may compute the adjustable part of its device identifier and associate the adjusted part with respective data (dataset) such that the adjustable part is indicative of its associated data. 
     The adjustable part broadcasted by the wireless device as part of its device identifier may be therefore indicative of the data available at the wireless device. 
     One or more of the mobile devices probing the wireless channel(s), in particular mobile devices which are in relatively close proximity to the wireless device, for example, 10, 20, 50 meters and/or the like and are thus in a transmission range of the wireless device via the wireless channel(s), may intercept the device identifier broadcasted by the wireless device. 
     The mobile device may compare between the adjustable part of the intercepted device identifier and the adjustable part of the device identifier of the wireless device which was previously intercepted. The mobile device may use the fixed part of the device identifier to determine that the currently intercepted device identifier and the previously intercepted device identifier are correlated with the same wireless device. 
     In case the adjustable part of the intercepted device identifier is the same (equal) as the adjustable part of the previously intercepted device identifier, specifically a most recently intercepted device identifier and assuming that the mobile device already communicated previously with the wireless device to receive (obtain) the data associated with the adjustable part of the previously intercepted device identifier, the mobile device may determine that no updated (new) data is available at the wireless device. The mobile device may therefore avoid establishing a connection and communicating with the wireless device. 
     However, in case the adjustable part of the intercepted device identifier is different from the adjustable part of the previously intercepted device identifier, specifically the most recently intercepted device identifier, the mobile device may determine that new and/or updated data is available at the wireless device. In such case the mobile device may establish a connection with the wireless device and communicate with the wireless device to receive the updated data. 
     After receiving the updated data, the mobile device may terminate the connection with the wireless device. Optionally one or more other mobile devices may connect and communicate with the wireless device to receive the updated data after the connection with the first mobile device is terminated. 
     Optionally, the adjustable part of the device identifier computed by one or more of the wireless devices may be indicative of at least part of a content of the data (dataset) associated with the device name that is available at the respective wireless device. Moreover, the adjustable part computed by one or more of the wireless devices may comprise a signature, for example, a checksum, a hash value and/or the like computed based on the content of the associated data available at the respective wireless device. Using the signatures extracted from the adjustable part of the device identifier, one or more of the mobile devices may very integrity of the associated data received from one or more of the wires devices. 
     According to some embodiments, one or more wireless devices may be deployed in one or more child hosting apparatuses configured to host one or more children in order to support one or more child safety applications, for example, child detection, child awareness, child vital signs monitoring and/or the like. In such embodiments, the wireless devices may be configured accordingly to collect data relating to one or more children located in the child hosting apparatuses, for example, a car child seat, a car seat, a stroller, a crib, a child walker, a trampoline and/or the like. 
     In such embodiments, one or more wireless devices may be deployed in a child hosting apparatus and configured to detect and monitor presence and/or safety of a child in the child hosting apparatus based on data captured by one or more sensors deployed in the child hosting apparatus. For example, the wireless device(s) may collect data collected by one or more contact and/or proximity sensors (e.g. proximity sensor, magnetic field sensor, microswitch, pressure sensor, discrete Hall Effect sensor, reed switch, etc.) deployed in a car child seat to determine whether one or more Isofix connectors are latched onto corresponding fittings on the car child seat which may be indicative of a child sitting in the car child seat. In another example, the wireless device(s) may collect data captured by one or more of contact and/or proximity sensors deployed to determine whether one or more seat belts of the vehicle have been passed through one or more seat belt guides of the car child seat and optionally if they are buckled. In another example, the wireless device(s) may collect pressure data collected by one or more pressure sensors deployed in the car child seat which may be analyzed to identify a child sitting in the car child seat. In another example, the wireless device(s) may monitor one or more vital life signs, for example, breathing, body temperature, heartbeat and/or the like of a child seating in the car child seat based on life signs data captured by one or more sensors deployed in the vehicle and/or in the car child seat. In another example, the wireless device(s) may determine whether the vehicle in which a child is seating in a car child seat is moving or not based on motion data captured by one or more motion sensors deployed in the vehicle and/or in the car child seat, for example, a gyroscope, an accelerometer and/or the like. 
     In such embodiments, one or more mobile devices typically associated with one or more users caring and/or attending to the child(s), for example, a parent, a nanny, a baby-sitter, a nurse, a guardian and/or the like may communicate with the wireless device(s) to collect the child safety related data collected by the wireless device(s). 
     Publishing availability of data at the wireless devices by broadcasting an adjustable device identifier associated and indicative of the available data may present significant benefits and advantages compared to existing methods and systems for collecting data collected by wireless devices. 
     First, the mobile device may identify availability of updated data at the wireless device based on its broadcasted device identifier without actually establishing a connection with the wireless device and without communicating with the wireless device. The mobile device may thus communicate with the wireless device only when updated data is available at the wireless device thus significantly reducing communication with the wireless device compared to the existing methods and systems in which the mobile device establishes a connection and communicates with the wireless device to check for availability of new data regardless of whether new data is available at the wireless device or not. Since wireless communication with the mobile device may be a major power consuming activity of the wireless device, reducing the communication between the wireless device and the mobile device may significantly reduce the power consumed by the two devices. This is of particular benefit to the wireless device which is typically battery powered and hence having limited power resources. The battery life of the wireless device may be thus significantly extended which may enable use of smaller and/or lower cost batteries, reducing battery change maintenance and/or the like. 
     Moreover, in addition to reducing the communication exchanged between the mobile device and the wireless device, terminating their wireless connection immediately after the mobile device receives the updated data may allow other mobile devices to connect to the wireless device in order to obtain the updated data available at the wireless device. This is in contrast to some of the existing methods in which the mobile device may maintain a continuous connection with the wireless device thus preventing other mobile devices to communicate with the wireless device and obtain the updated data, thus limiting the application to a single mobile device, specifically when using wireless channels which do not support multiple connections with the wireless device, for example, Bluetooth, BLE, ZigBee and/or the like. 
     Furthermore, adjusting the device identifier, specifically the adjustable part of the device identifier to include a signature computed based on the content of the data available at the wireless device may enable the mobile device(s) to efficiently verify integrity of the content of the data received from the wireless device thus significantly increasing robustness, reliability and/or accuracy of the received data. 
     Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of construction and the arrangement of the components and/or methods set forth in the following description and/or illustrated in the drawings and/or the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways. 
     As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon. 
     Any combination of one or more computer readable medium(s) may be utilized. The computer readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The computer readable storage medium may be, for example, but is not limited to, an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing. A non-exhaustive list of more specific examples of the computer readable storage medium includes the following: a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanically encoded device such as punch-cards or raised structures in a groove having instructions recorded thereon, and any suitable combination of the foregoing. A computer readable storage medium, as used herein, is not to be construed as being transitory signals per se, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through a waveguide or other transmission media (e.g., light pulses passing through a fiber-optic cable), or electrical signals transmitted through a wire. 
     Computer program code comprising computer readable program instructions embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to wireless, wire line, optical fiber cable, RF, etc., or any suitable combination of the foregoing. 
     The computer readable program instructions described herein can be downloaded to respective computing/processing devices from a computer readable storage medium or to an external computer or external storage device via a network, for example, the Internet, a local area network, a wide area network and/or a wireless network. The network may comprise copper transmission cables, optical transmission fibers, wireless transmission, routers, firewalls, switches, gateway computers and/or edge servers. A network adapter card or network interface in each computing/processing device receives computer readable program instructions from the network and forwards the computer readable program instructions for storage in a computer readable storage medium within the respective computing/processing device. 
     The computer readable program instructions for carrying out operations of the present invention may be written in any combination of one or more programming languages, such as, for example, assembler instructions, instruction-set-architecture (ISA) instructions, machine instructions, machine dependent instructions, microcode, firmware instructions, state-setting data, or either source code or object code written in any combination of one or more programming languages, including an object oriented programming language such as Smalltalk, C++ or the like, and conventional procedural programming languages, such as the “C” programming language or similar programming languages. 
     The computer readable program instructions may execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user&#39;s computer through any type of network, including a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). In some embodiments, electronic circuitry including, for example, programmable logic circuitry, field-programmable gate arrays (FPGA), or programmable logic arrays (PLA) may execute the computer readable program instructions by utilizing state information of the computer readable program instructions to personalize the electronic circuitry, in order to perform aspects of the present invention. 
     Aspects of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer readable program instructions. 
     The flowchart and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of instructions, which comprises one or more executable instructions for implementing the specified logical function(s). In some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts or carry out combinations of special purpose hardware and computer instructions. 
     Referring now to the drawings,  FIG.  1    presents flowcharts of exemplary processes executed by a wireless device and a mobile device for wirelessly broadcasting and detecting data indicative of updated data available at the wireless device, according to some embodiments of the present invention. 
     An exemplary process  110  may be executed by a wireless device  102  for collecting data and transferring it to one or more mobile devices  104  via one or more wireless channels. The wireless device  102  may broadcast, via the wireless channel(s), a device identifier which may be adjusted to indicate of the collected data that is currently available at the wireless device  102 . 
     An exemplary process  130  may be executed by each of one or more mobile devices  104  for communicating with the wireless device  102  to receive (obtain) the data available at the wireless device  102 . Specifically, each mobile device  104  may be configured to probe the wireless channel(s) and, when in a transmission range of the wireless device  102 , intercept the indicative data broadcasted by the wireless device  102  without establishing a communication session with the wireless device  102 . 
     The mobile device  104  may compare the intercepted indicative data to previously intercepted indicative data associated with previous data that was previously available at the wireless devices  102  in order to determine whether updated (new) data is currently available at the wireless device  102  compared to the previous data. Assuming the previous data was already received by the mobile device  104 , only when the mobile device  104  determines that updated data is available at the wireless device  102  the mobile device  104  may establish a connection and communicate with the wireless device  102  to receive the updated data. Otherwise, since no updated data is available, the mobile device  104  may avoid connecting and communicating with the wireless device  102 . 
     Reference is also made to  FIG.  2 A  and  FIG.  2 B  which are schematic illustrations of an exemplary system comprising a wireless device configured to broadcast data indicative of updated data available at the wireless device and one or more mobile devices configured to detect the indicative data and communicate with the wireless device to acquire the updated data, according to some embodiments of the present invention. 
     An exemplary system  200  may include a wireless device  102 , for example, a data collection device, a sensing device, an IoT device and/or the like configured to communicate with one or more other devices via one or more wireless channels  106 . In particular, the wireless channel(s)  106  may include short range, close proximity wireless channels  106  configured to operate in a limited range, for example, between a few meters and few tens of meters. The wireless channel(s)  106  may include, for example, Bluetooth, BLE, ZigBee, Z-WAVE, WLAN (e.g. Wi-Fi) and/or the like. 
     For example, the wireless device  102  may communicate with one or more mobile devices  104  typically but not necessarily associated with one or more users  108  and are thus mobile since they are held, worn and/or otherwise carried by the users. The mobile devices  104  may therefore include client devices typically uniquely associated with users, for example, a Smartphone, a Smartwatch, a wearable device, a Radio Frequency Identification (RFID) tag, a proprietary device and/or the like. However, the mobile devices  104  may further mobile devices which are not private and are not necessarily uniquely associated with users, for example, a key holder, a proprietary device specifically designed for communicating with wireless device such as the wireless device  102  and/or the like. 
     The wireless device  102  may communicate with each mobile device  104  via on one or more of the wireless channel(s)  106  typically established Ad hoc to directly connect between the two wireless devices. Such Ad hoc connection may be a common mode of operation for at least some of the wireless channels  106 , for example, Bluetooth, BLE, Zig-Bee and even direct Wi-Fi. However, the wireless device  102  may optionally communicate with one or more of the mobile devices  104  via an infrastructure network, for example, a Wi-Fi network established using one or more infrastructure devices and/or equipment, for example, a router, a gateway and/or the like. 
     For brevity, the system  200  is presented and described for only a single wireless device  102 . This, however, should not be construed as limiting since a plurality of wireless device  102  may be deployed and configured to communicate with one or more other wireless devices such as the mobile devices  104 . 
     The wireless device  102  may be deployed to collect data, for example, sensory data, imagery data, audible data and/or the like captured by one or more sensors and/or other sensing devices which are communicatively coupled to the wireless device  102 . 
     The mobile device  104  typically associated with a user  108  may communicate with the wireless device  102  to obtain, for example, receive, fetch, collect and/or the like at least some of the data collected by the wireless device  102 . The mobile device  104  may process the data and may further initiate one or more actions accordingly. For example, the mobile device  104  may be configured to generate one or more events based on the content of the data received from the wireless device  102  and/or based on analysis of the received data. The mobile device  104  may be further configured to initiate one or more actions, for example, generate an indication, an alert, a notification and/or the like to notify the user(s)  108  of one or more of the events. 
     According to some embodiments, the wireless device  102  may be deployed to support one or more child safety applications, for example, child detection, child vital signs monitoring and/or the like. The wireless device  102  may be therefore designed, configured and/or operated to collect data relating to one or more children located in one or more locations, specifically in one or more child hosting apparatuses configured to host one or more children. Such child hosting apparatuses may include, for example, a car child seat, a car seat, a stroller, a crib, a child walker, a trampoline and/or the like. 
     The exemplary child hosting apparatuses mentioned herein should not be construed as limiting since wireless devices such as the wireless device  102  may be deployed to support one or more of the child safety applications for in practically any child hosting apparatus capable in which one or more children may be located, present and/or hosted. 
     In such embodiments, the wireless device  102  may be deployed in, near and/or around the child hosting apparatus and may be configured to detect and monitor presence and/or safety of a child hosted in the child hosting apparatuses based on data captured by one or more sensors  206  deployed in, near and/or around the child hosting apparatus. 
     For example, the wireless device  102  may communicate with one or more contact and/or proximity sensors  206 , for example, a proximity sensor, a magnetic field sensor, a microswitch, a pressure sensor, a discrete Hall Effect sensor, a reed switch and/or the like deployed in a car child seat to collect sensory data indicative whether one or more Isofix connectors of the child seat are latched onto corresponding fittings on the seat which may be indicative of a child sitting in the seat. 
     Moreover, based on the sensory data received from the contact and/or proximity sensors  206 , the wireless device  102  may further determine whether the Isofix connector(s) of the car child seat are properly and/or securely latched onto the corresponding fittings. 
     In another example, the wireless device  102  may collect data captured by one or more of contact and/or proximity sensors  206  deployed to determine whether one or more seat belts of the vehicle have been passed through respective one or more seat belt guides of the car child seat and optionally if the seat belts are securely buckled.

     In another example, the wireless device  102  may be deployed in a vehicle to monitor presence of one or more children in the vehicle, in particular in the back seat(s) of the vehicle. In such case, the wireless device  102  may connect to one or more sensors  206  such as the pressure sensor deployed to measure pressure on one or more of the back seats. Based on the pressure measurements captured by the pressure sensor(s)  206 , the wireless device  102  may identify whether one or more people are sitting in the back seat. Moreover, based on calculation of the weight of the person(s) sitting in the back seat compared to a predefined threshold indicative of a child&#39;s weight, the wireless device  102  may determine whether each of the detected person(s) is a child or not.

In such case, the wireless device  102  may connect to pressure sensors  206  deployed and configured to measure pressure a sitting and/or lying surface of the stroller, the crib and/or the like. Based on the pressure measurements captured by the pressure sensor(s)  206 , the wireless device  102  may identify whether a child is present in the stroller, the crib and/or the like. 
     In another example, the wireless device  102  may be deployed to monitor one or more vital life signs, for example, breathing, body temperature, heartbeat and/or the like of one or more children located in one or more of the child hosting apparatuses. In such case, the wireless device  102  may collect vital life signs data captured by one or more sensors  206  deployed and configured as known in the art to measure one or more of the vital life signs of one a child present in the child hosting apparatus. The wireless device  102  may optionally process and/or analyze the sensory data to determine a status of the monitored child based on the measured vital signs. 
     In another example, the wireless device  102  may determine whether the vehicle in which a child is seating in a car child seat is moving or not based on motion data captured by one or more motion sensors  206  deployed in the vehicle and/or in the seat, for example, a gyroscope, an accelerometer and/or the like 
     In such embodiments, the mobile devices  104  associated with one or more users  108  caring and/or attending to the child(s), for example, a parent, a nanny, a baby-sitter, a nurse, a guardian and/or the like may include one or more devices which are in common and/or applicable use the associated user(s)  108 .

     The mobile device  104  may communicate with the wireless device  102  to receive the data relating to the child(s) that was collected by the wireless device  102 . Based on the content of the received data and/or based on analysis of the received data, the mobile device  104  may generate one or more events relating to the child(s).

     Via the wireless interface  202 , the wireless device  102  may communicate with one or more of other devices, for example, one or more of the mobile devices  104 . 
     The data collection engine  204  may be configured to collect data, for example, sensory data captured by one or more sensors  206 , for example, a pressure sensor, a proximity sensor, a contact sensor, an imaging sensor, an audio sensor and/or the like. Each of the sensor(s)  206  may be therefore communicatively coupled to the wireless device  102 , specifically to the data collection engine  204  via one or more wired and/or wireless connections, for example, a serial channel, a Universal Serial Bus (USB) port, a Radio Frequency (RF) channel and/or the like. optionally, one or more of the sensor(s)  206  are integrated in the mobile device  102 . 
     Optionally, the data collection engine  204  may be further configured to process and/or analyze the collected data and/or part thereof. 
     The data collection engine  204  may be implemented, utilized and/or facilitated using one or more technologies, architectures and/or modes as known in the art. For example, the data collection engine  204  may be utilized by one or more software modules, for example, a process, a script, an application, an agent, a utility, a tool, an Operating System (OS) and/or the like each comprising a plurality of program instructions stored in a non-transitory medium (program store), for example, a storage media (e.g. Read Only Memory (ROM), Flash array, etc.) included in the wireless device  102  and executed by one or more processors and/or controllers of the wireless device  102 . In another example, the data collection engine  204  may be utilized using one or more hardware elements (modules) integrated, utilized and/or otherwise available in the wireless device  102 , for example, a circuit, a component, an Integrated Circuit (IC), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA), a Digital Signals Processor (DSP), and/or the like. In another example, the data collection engine  204  may be utilized by a combination of one or more software modules and one or more of the hardware modules. 
     Each mobile device  104  may include a wireless interface  210  such as the wireless interface  202  for connecting to one or more of the wireless channels  106 , for example, Bluetooth, BLE, ZigBee, Z-WAVE, WLAN and/or the like, a data processing engine  212  for executing the process  130 , a user interface  214  for interacting with one or more associated users  108  and optionally an Input/Output (I/O) interface  216 . 
     Via the wireless interface  210 , the mobile device  104  may communicate with one or more other devices, for example, the wireless device  102  in order to receive the data collected by the wireless device  102 , for example, the sensory data and/or data derived from the sensory data. 
     The data processing engine  212  may be configured to process data, specifically the data received from the wireless device  102 , for example, the sensory data captured by one or more of the sensor(s)  206  and/or data derived from the captured sensory data. Based on the content of the received data and/or based on analysis of the received data, the data processing engine  212  may generate one or more events relating to the data collected by the wireless device  102 , for example, the sensory data. The data processing engine  212  may further initiate one or more actions to report of the generated events, for example, generate an indication, an alert, a notification and/or the like to notify the user(s)  108  of one or more of the events. 
     As described for the data collection engine  204 , the data processing engine  212  may be implemented, utilized and/or facilitated using one or more of the technologies, architectures and/or modes known in the art. For example, the data processing engine  212  may be utilized by one or more software modules, for example, a process, a script, an application, an agent, a utility, a tool, an OS and/or the like each comprising a plurality of program instructions stored in a storage media of the mobile device  104  and executed by one or more processors, homogenous or heterogeneous, of the mobile device  104 . In another example, the data processing engine  212  may be utilized using one or more hardware modules integrated, utilized and/or otherwise available in the mobile device  104 , for example, a circuit, a component, an IC, an ASIC, an FPGA, a DSP, a Graphic Processing Unit (GPU) and/or the like. In another example, the data processing engine  212  may be utilized by a combination of one or more software modules and one or more of the hardware modules. 
     The user interface  214  may include one or more Human-Machine Interfaces (HMI) for interacting with the user  108 , in particular, for alerting the user  108  of one or more of the events generated by the data processing engine  212 . For example, the user interface  214  may include one or more visual output HMIs, for example, a screen, one or more light sources such as, for example, a Light Emitting Diode (LED) and/or the like for generating one or more visual indications, notifications and/or alerts directed to notify the user  108  of one or more of the events. In another example, the user interface  214  may include one or more audio output HMIs, for example, a speaker, a buzzer, a piezo and/or the like for generating one or more audible indications, notifications and/or alerts directed to notify the user  108  of one or more of the events. In another example, the user interface  214  may include one or more tactile HMIs, for example, a vibrating element and/or the like for generating one or more motion indications and/or alerts directed to notify the user  108  of one or more of the events. 
     The optional I/O interface  216  may include one or more wired and/or wireless interfaces configured to connect to one or more channels, networks, interconnections and/or the like for communicating with one or more other devices. For example, the I/O interface  216  may include one or more long range wireless interfaces for connecting to one or more wireless networks, for example, a cellular network and/or the like such that the mobile device  104  may connect to one or more remote servers, cloud services, cloud resources and/or the like via one or more networks, for example, the internet. In another example, the I/O interface  216  may include one or more wired and/or wireless interfaces through which the mobile device  104  may connect to one or more other device and relay the events and/or indications to the other device(s). For example, the mobile device  104  may be configured as an add-on device attachable to one or more other devices, for example, a Smartphone. In such case, the mobile device  104  may communicate with the Smartphone via one or more interfaces provided by the I/O interface  216 , for example, USB, Near-Field Communication (NFC), RF and/or the like. 
     The processes  110  and  130  are described for the single wireless device  102 . This however, should not be construed as limiting since one or more of the mobile devices  104  may each initiate a respective process  130  to communicate with a plurality of wireless devices such as the wireless device  102  to receive updated data collected by the respective wireless device  102  executing a respective process  110 . 
     Complementary, while the processes  110  and  130  are described for a wireless device  102  interacting with a single mobile device  104 , the wireless device  102  may execute a plurality of processes  110  each for interacting and communicating with a respective one of a plurality of mobile devices  104  in order to provide updated data to each of the mobile devices  104 . Specifically, since the wireless channel  106  may typically support a single connection with a single mobile device  104  at every given time, after completing a process  110  with a first mobile device  104  by terminating the connection, the wireless device  102  may initiate another process  110  for communicating with a second mobile device  104 . 
     For brevity, the description herein states that the process  110  is executed by the wireless device  102 . It should be noted however, that in practice the process  110  may be executed by the data collection engine  202  executed by the wireless device  102 . Similarly, the description herein states that the process  130  is executed by the mobile device  104 . It should be noted however, that in practice the process  130  may be executed by the data processing engine  212  executed by the mobile device  104 . 
     Also, while for brevity the wireless device  102  and the mobile device  104  described in the processes  110  and  130  may communicate via a single wireless channel  106 , the wireless device  102  and the mobile device  104  may optionally communicate and/or interact with each other via multiple wireless channels  106 . 
     The wireless device  102  and the mobile device  104  may initiate the processes  110  and  130  respectively independently of each other such that the one or both of the devices may execute at least some steps of their respective processes independently of each other. 
     However, some of the steps of the processes  110  and  130  require interaction and potentially communication between the wireless device  102  and the mobile device  104 . As described herein before, the transmission range of the wireless channel  106  used for communication between the wireless device  102  and the mobile device  104  to communicate with each other may be limited to a certain distance, for example, few meters, only when the wireless device  102  and the mobile device  104  are within the certain distance from each other, i.e., the certain distance, for example, 10 meters. 
     Therefore, only when the mobile device  104  and the wireless device  102  are within the certain distance of each other, for example, 10 meters, the wireless device  102  and the mobile device  104  may establish a connection and communicate with each other via the wireless channel  106  and execute the steps of the processes  110  and  130  that require interaction and communication. 
     As shown at  112 , the process  110  executed by the wireless device  102  may start with the wireless device  102  collecting data. 
     For example, the wireless device  102  may communicate with one or more of the sensor(s)  206  to collect sensory data captured by the sensor(s)  206 , for example, pressure readings, proximity measures, imagery data and/or the like. 
     In particular, in case the wireless device  102  is deployed to support one or more of the child safety applications, the wireless device  102  may communicate with one or more sensors  206  deployed in, near and/or around one or more of the child hosting apparatuses which are configured to capture sensory data relating to one or more children located and/or present in the child hosting apparatus(s). 
     Moreover, the wireless device  102  may generate data based on the sensory data collected from the sensor(s)  206 . 
     For example, assuming the sensor(s)  206  deployed in the child hosting apparatus comprise one or more pressure sensors  206 , the wireless device  102  may determine whether a child is located in the child hosting apparatus or not. Moreover, based on the captured pressure readings, the wireless device  102  may further compute a weight of the child seating and/or located in the child hosting apparatus. 
     The wireless device  102  may further determine whether the collected data is new, i.e., updated compared to previously collected data. 
     For example, assuming the wireless device  102  collects sensory data captured by the sensor(s)  206 , the wireless device  102  may compare the collected sensory data to previous sensory data previously captured by the sensor(s)  206 . Moreover, the wireless device  102  may optionally generate updated data, for example, updated presence data relating to a child located in the child hosting apparatus, weight data based on updated sensory data captured by the pressure sensor(s)  206  deployed in the child hosting apparatus and/or the like. 
     Optionally, one or more of the sensor(s)  206  may include one or more status mechanisms and/or indicators, for example, a status register, a status signal, an interrupt signal and/or the like which may be operated by the sensor(s)  206  to indicate the wireless device  102  that new sensory data is available. In such case, the wireless device  102  may first determine, based on the status mechanisms and/or indicators, whether updated sensory data is available and in case such updated sensory data is available, the wireless device  102  may communicate with the sensor(s)  206  to collect the updated sensory data. 
     As shown at  114 , which is a conditional step, the process  110  may branch to  116  in case the wireless device  102  determines that the collected data comprises updated data compared to previously collected data. Otherwise, the process  110  may branch to  118  in case the wireless device  102  determines that the collected data is not updated compared to previously collected data. 
     As shown at  116 , the wireless device  102  may adjust a device identifier of the wireless device  102 . In particular, the adjusted identifier computed by the wireless device  102  is associated with the updated data and is therefore indicative of availability of the updated data compared to previous data that was previously available at the wireless device  102  which was associated with a different, pre-adjustment, device identifier. 
     Each wireless device, for example, the wireless device  102  and the mobile device  104  using the wireless channel  106  may typically broadcast a device identifier via one or more of the wireless channel  106 . The device identifier broadcasted by the wireless device  102  may be defined by one or more communication protocols applicable for the wireless channel  106  as known in the art to uniquely and deterministically identify each device communicating via the wireless channel  106 . Each wireless device may broadcast its device name and device identifier, continuously, periodically and/or on demand as defined by the applicable communication protocol(s). 
     The device identifier may include a fixed part to uniquely and deterministically identify the wireless device  102 , for example, a network identifier such as, for example, a Media Access Controller (MAC) Address which is fixed and unique for each device, an Internet Protocol (IP) address which may be unchangeable at least the duration of the communication session and/or the like. 
     However, the device identifier of one or more of the wireless devices may comprise an adjustable part, for example, a device name, a device status and/or the like which may be dynamically changed and/or adjusted by the respective wireless device, for example, the wireless device  102 . 
     The wireless device  102  may therefore adjust the adjustable part of its device identifier, for example, its device name, its device status and/or the like to indicate availability of the updated data. Specifically, the adjustable part of the device identifier associated with the updated data may be adjusted to be different from the adjustable part of a previous device identifier of the wireless device  102  which was associated with data that was previously available at the wireless device  102 . The different device identifier, specifically the different adjustable part of the device identifier may therefore indicate that the updated data currently available at the wireless device  102  is different from the previously available data. 
     Adjusting the adjustable part of the device identifier to indicate data availability may be implemented using a plurality of method and/or techniques, optionally according to the communication protocol(s) applicable for the wireless channel  106 . For example, assuming the adjustable part of the device identifier of the wireless device  102 , for example, the device name is defined to include a total of 8 characters, the first four characters may identify a type of the wireless device  102 , for example, WDT1 (Wireless Device Type 1) and the last four characters may be incremented every time new (updated) data is available at the wireless device  102 . In such case, a first device name may comprise a value WDT10000, a second device name adjusted after updated data is available at the wireless device  102  may comprise a value WDT10001 and so on. 
     Optionally, the adjustable part of the device identifier may be indicative of at least part of a content of the data available at wireless device  102 . As such, every time the wireless device  102  collects updated data, the wireless device  102  may adjust adjustable part of its device identifier based on the content of the updated data to indicate availability of the updated data. In other words, when data available at the wireless device  102  is updated compared to previously available data, the content of the updated data is essentially different from the content of the previously available data. The device identifier&#39;s adjustable part derived from the content of the updated data may be therefore different from the adjustable part a previous device identifier derived from the content of the previously available data. 
     For example, assuming the wireless device  102  is deployed to support one or more of the child safety applications and configured to collect sensory data from one or more sensors  206  deployed in the child hosting apparatus, for example, a car child seat. Further assuming the adjustable part of the device identifier of the wireless device  102  is defined to have a total of 8 characters. In such case, the first four characters may identify the type of the wireless device  102 , for example, WDT1, a fifth character may indicate whether a child is seating in the car child seat and the last three characters may be incremented every time updated data is available at the wireless device  102 . 
     Optionally, the adjustable part of the device identifier may comprise a signature computed based on content of the data available at wireless device  102 . For example, the signature computed by the wireless device  102  may comprise a checksum computed by the wireless device  102  for the content of the updated data and/or part thereof. In another example, the signature computed by the wireless device  102  may comprise a hash value computed by the wireless device  102  using one or more hash functions based on the content of the updated data and/or part thereof. For example, assuming the adjustable part of the device identifier of the wireless device  102  is defined to have a total of 8 characters, where the first four characters may identify a type of the wireless device  102 , for example, WDT1, the fifth character is reserved and the last three characters comprise the signature computed for the data available at the wireless device  102 . 
     Optionally, the wireless device  102  creates a log record comprising a plurality of data items and/or datasets collected by the wireless device  102  and accumulated over time. For example, assuming the wireless device  102  collects the sensory data from the sensor(s)  206 , the wireless device  102  may create a log record comprising a plurality of sensory datasets captured by the sensor(s)  206  and accumulated in the wireless device  102  during a certain time, for example, a certain recent time period and/or the like. 
     Optionally, one or more of the data items and/or datasets collected by the wireless device  102  are time stamped to indicate their time of capture and/or creation. The time stamp may be included in the data available at the wireless device  102  in association with the data item for which it was created. The collected data may be time stamped by the wireless device  102  itself and/or by one or more other devices, for example, one or more of the sensors  206 . 
     As shown at  118 , the wireless device  102  may broadcast its device identifier comprising the fixed part uniquely identifying the wireless device  102  and the adjustable part which may be indicative of data available at the wireless device  102 . 
     The wireless device  102  may repeat steps  112 - 118  in a plurality of iterations to collect data and check whether the collected data is new and updated compared to previously collected data and may adjust its device identifier name accordingly if needed, in particular the adjustable part of its device identifier. 
     As shown at  132 , the process  130  executed by the mobile device  104  may start with the mobile device  104  probing the wireless channel  106  in attempt to detect one or more wireless devices  102 . 
     As stated herein before, the wireless device  102  and the mobile device  104  may initiate their respective processes  110  and  130  independently of each other. In particular, the wireless device  102  may execute steps  112 - 118  of the process  110  to check and collect updated data, adjust its device identifier accordingly and broadcast it via the wireless channel  106  independently of the mobile device  104  which may probe the wireless channel  106  in attempt to detect the wireless device  102 , specifically the device identifier broadcasted by the wireless device  102 . 
     The mobile device  104  may apply one or more operation modes for probing the wireless channel  106 . For example, the mobile device  104  may continuously probe the wireless channel  106 . In another example, the mobile device  104  may probe the wireless channel  106  periodically every predefined time period, for example, 0.25 seconds, 0.5 seconds, 1 second, and/or the like. 
     The mobile device  104  may apply one or more methods, techniques and/or implementations for probing the wireless channel  106  in attempt to detect the wireless device(s)  102  including, for example, operating the wireless interface  210  to probe the wireless channel  106 , intercepting data from the wireless channel  106 , analyzing the intercepted data and/or the like. 
     For example, assuming the mobile device  104  is a simple device implementing the data processing engine  212  in hardware and/or using simplistic embedded software. In such case, the data collection engine  202  may operate and/or execute one or more hardware and/or software modules to operate the wireless interface  210  to continuously and/or periodically probe the wireless channel  106 , intercept data from the wireless channel  106  and analyze the intercepted data. 
     In another example, assuming the mobile device  104 , for example, a Smartphone executes an OS such as, for example, Android and/or the like configured to support constantly active services. In such case the data processing engine  212  may employ one or more constantly active services executed by the mobile device  104  in a foreground environment of the OS to probe the wireless channel  106 . Using the constantly active service(s), the data processing engine  212  may operate the wireless interface  210  to continuously and/or periodically probe the wireless channel  106  and intercept data from the wireless channel  106 . 
     In another example, assuming the mobile device  104 , for example, a Smartphone executes an OS such as, for example, iOS and/or the like which do not support constantly active services. In such case the data processing engine  212  may use one or more services provided by the OS, for example, a beacon detection service configured to continuously and/or periodically probe the wireless channel and detect one or more beacon signals transmitted by one or more wireless devices via the wireless channel  106 . The beacon detection service executed by the OS may be configured to invoke one or more inactive services in response to detection of one or more such beacon signals. The invoked service(s) may be then used to continuously and/or periodically probe the wireless channel  106  and intercept data transmitted via the wireless channel  106  by one or more of the wireless devices. 
     As shown at  134 , the mobile device  104  may intercept the device identifier of the wireless device  102  comprising the fixed part uniquely identifying the wireless device  102  and the adjustable part which may be indicative of data available at the wireless device  102 . 
     It should be noted that since the wireless device  102  may independently broadcast its device identifier, intercepting the device identifier of the wireless device  102  does not require the mobile device  104  to establish a connection with the wireless device  102  and/or otherwise communicate with the wireless device  102  in any way. 
     Since the transmission range of the wireless device  102  via the wireless channel  106  may be limited to the certain distance, for example, few meters (e.g. 10, 20, 50 meters), the mobile device  104  may intercept the device identifier broadcasted by the wireless device  102  only when the mobile device  104  is within the certain distance from the wireless device  102 , for example, 10, 20, 50 meters. However, while the mobile device  104  is further away from the wireless device  102 , i.e. more than the certain distance from the wireless device  102 , the mobile device  104  may be outside the transmission range of the wireless device  102  and may be thus unable to intercept the device identifier broadcasted by the wireless device  102  via the wireless channel  106 . 
     Therefore, since the mobile device  104  may be able to intercept the data broadcasted by the wireless device via the wireless channel  106 , for example, the device identifier only when the mobile device  104  is in the transmission range of the wireless device  102 , the mobile device  104  may detect moving in and out of the transmission range of the wireless device  102 . Since such movement of the mobile device  104  in and out of the transmission range of the wireless device  102  may be interpreted as moving towards and away from the wireless device  102  respectively, the mobile device  104  may determine whether it is moving closer to or further away from the wireless device  102 . 
     Optionally, the mobile device  104  may be configured to generate one or more events in response to detecting that the mobile device  104  is in the transmission range of the wireless device  102 . For example, the mobile device  104  may generate one or more events when first entering the transmission range of the wireless device  102  in response to detecting, for the first time compared to recent probing of the wireless channel  106 , the device identifier broadcasted by the wireless device. 
     Optionally, the mobile device  104  may be configured to generate one or more events in response to detecting that the mobile device  104  is out of the transmission range of the wireless device  102 . For example, the mobile device  104  may generate one or more events when exiting the transmission range of the wireless device  102  after previously located within the transmission range based on in ability to intercept the device identifier broadcasted by the wireless device compared to recent probing of the wireless channel  106  in which the device identifier was successfully intercepted. 
     Moreover, the mobile device  104  may be configured to generate one or more visual, audible and/or tactile indications, notifications and/or alerts in response to one or more of the events, for example, detecting one or more nearby wireless device  102 , moving further away from one or more of the nearby wireless device(s)  102  beyond the certain distance and/or the like. 
     In particular, in case the wireless device  102  is deployed in one or more of the child hosting apparatuses to support one or more of the child safety applications and is configured to collect sensory data from one or more sensors  206  deployed to capture sensory data relating to one or more children located and/or present in the child hosting apparatus(s). In such case, the events generated by the mobile device  104  may comprise one or more child safety related events identified based on the updated data received from the wireless device  102 , typically based on the sensory data captured by one or more of the sensor(s)  206  deployed to capture sensory data relating to the one or more children. 
     For example, the mobile device  104  may generate one or more alerts, indications and/or notifications when moving away from the wireless device  102  to alert the user(s)  106  that a child may be left in the child hosting apparatus, for example, the child seat. In another example, the mobile device  104  may generate one or more alerts, indications and/or notifications when getting closer and detecting a wireless device  102  deployed in a child hosting apparatus, for example, a car child seat to indicate to the user(s)  106  that a connection was established with the wireless device  102 . In another example, the mobile device  104  may generate one or more alerts, indications and/or notifications in case one or more of the vital signs of a child located in a child hosting apparatus (e.g. crib, stroller, etc.) exceed predefined values. In another example, the mobile device  104  may generate one or more alerts, indications and/or notifications in case the vehicle in which a child is seating in a car child seat is moving. In another example, the mobile device  104  may generate one or more alerts, indications and/or notifications in case a child is not properly positioned in the child hosting apparatus, for example, in case one or more Isofix and/or straps of a car child seat are not properly secured and/or strapped. 
     Reference is now made to  FIG.  3   , which presents schematic illustrations of exemplary positioning scenarios of a mobile device with respect to a wireless device according to which the mobile device may initiate one or more actions, according to some embodiments of the present invention. 
     Illustrations  302 ,  304  and  306  present a sequence of movement of a mobile device such as the mobile device  104  towards a wireless device such as the wireless device  102 . 
     As seen in  302 , the mobile device  104  which is moving towards the wireless device  102  is out of the transmission range (coverage area) of one or more wireless channels such as the wireless channel  106  of the wireless device  102 . The mobile device  104  is therefore unable to intercept the device identifier broadcasted by the wireless device  102  via the wireless channel  106  and may thus not detect the wireless device  102 . 
     As seen in  304 , the mobile device  104  moving closer to the wireless device  102  enters the transmission range of the wireless device  102  via the wireless channel  106 . The mobile device  104  may therefore intercept the device identifier broadcasted by the wireless device  102  via the wireless channel  106  and may detect the wireless device  102 . 
     As seen in  306 , the mobile device  104  moving away from the wireless device  102  exits the transmission range of the wireless device  102  via the wireless channel  106 . The mobile device  104  may therefore again be unable to intercept the device identifier broadcasted by the wireless device  102  via the wireless channel  106  and may therefore be unable to detect the wireless device  102 . 
     The mobile device  104  may generate one or more events to reflect detection of the wireless device  102  and/or inability to detect the wireless device  102  which are indicative of the distance between the mobile device  104  and the wireless device  102 . The wireless device  102  may further initiate one or more actions, for example, generate an alert, an indication and/or the like to indicate moving closer and/or further from the wireless device  102  based on the presence and/or absence of data transmission (broadcasting) originating from the wireless device  102   
     Reference is made once again to  FIG.  1   . 
     As shown at  136 , the mobile device  104  may compare between the intercepted device identifier of the wireless device  102  and a previously intercepted device identifier of the wireless device  102 , specifically a most recently intercepted device identifier. In particular, the mobile device  104  may compare between the adjustable part of the intercepted device identifier and the adjustable part of the previously intercepted device identifier. 
     While the (currently) intercepted device identifier and the previously intercepted device identifier may be slightly different due to their possibly different adjustable parts, the mobile device  104  may use the fixed part of the device identifier to correlate the currently intercepted device identifier and the previously intercepted device identifier with the same wireless device  102 . 
     In other words, the mobile device  104  may identify the wireless device  102  based on the fixed part of its device identifier which is identical during all device identifier broadcasts made by the same wireless device  102 . After correlating the currently and previously intercepted device identifiers with the same wireless device  102 , the mobile device  104  may compare the values of the adjustable parts of the currently and previously intercepted device identifiers. 
     As shown at  138 , which is a conditional step, the process  130  may branch to  140  in case the intercepted device identifier of the wireless device  102  is different from the previously intercepted device identifier of the wireless device  102 , specifically in case the adjustable part of the intercepted device identifier is different from the adjustable part of the previously intercepted device identifier. Otherwise, in case the adjustable part of the intercepted device identifier of the wireless device  102  is similar to the adjustable part of the previously intercepted device identifier of the wireless device  102 , the process  130  may branch back to  132  to continue probing the wireless channel  106 . 
     As described herein before, the difference in the intercepted device identifier compared to the previously intercepted device identifier may be indicative of updated data available at the wireless device  102 . In particular, it is assumed that the mobile device  104  already received the data which was available at the wireless device  102  and was associated with the previously intercepted device identifier. 
     Therefore, in case the currently intercepted device identifier is the same as the previously intercepted device identifier, the mobile device  104  may determine that no updated data is available for it at the wireless device  102 . However, in case the currently intercepted device identifier, specifically the adjustable part of the currently intercepted device identifier is different from the adjustable part of the previously intercepted device identifier, the mobile device  104  may determine that there is updated data available at the wireless device  102 . 
     In case the device identifier is the same, the mobile device  104  may go back to  132  and continue probing the wireless channel  106  for one or more purposes, for example, detect a change in the device identifier of the wireless device  102 , detect leaving the transmission range of the wireless device  102 , detect one or more other wireless devices  102  and/or the like. 
     As shown at  120  of the process  110  and complementary at  140  of the process  130 , the mobile device  104  may establish a connection with the wireless device  102  via the wireless channel  106  according to one or more of the communication protocols applicable for the wireless channel  106  as known in the art. 
     As shown at  122  of the process  110  and complementary at  142  of the process  130 , the wireless device  102  may transmit the updated data to the mobile device  104  receiving the updated data. 
     Optionally, in case the wireless device  102  creates the log record comprising the plurality of data items and/or datasets collected and accumulated at the wireless device  102  over time, the mobile device  104  may communicate with the wireless device  102  to receive the log record and/or part thereof. Specifically, the mobile device  104  may interact with the wireless device  102  to obtain one or more data items and/or datasets collected and accumulated at the wireless device  102  during the time since the mobile device  104  most recently communicated with the wireless device  102  to receive data collected by the wireless device  102 . Moreover, in case the plurality of data items and/or datasets included in the log record are time stamped, the mobile device  104  may communicate with the wireless device  102  to determine, based on their time stamps, which of the data items and/or datasets should be transferred to the mobile device  104 . 
     As shown at  124  of the process  110  and complementary at  144  of the process  130 , after receiving the updated data, the mobile device  104  may terminate the connection with the wireless device  102 . 
     Optionally, after the connection between the mobile device  104  and the wireless device  102  is terminated, one or more other mobile devices  104 , specifically mobile device(s)  104  which are in the transmission range of the wireless device  102 , may establish a connection with the wireless device  102  via the wireless channel  106  to receive the updated data available at the wireless device  102 . Each of the other mobile device(s)  104  may execute a process such as the process  130  to intercept the device identifier of the wireless device  102  and establish the connection with the wireless device  102  in response to detecting that the intercepted device identifier is adjusted (changed) compared to the device identifier of the wireless device  102  previously intercepted by the respective other mobile device  104 . 
     Optionally, in case the device identifier, specifically the adjustable part of the intercepted device identifier associated with the updated data comprises a signature of the content of the updated data or part thereof, after receiving the updated data, the mobile device  104  may verify integrity of the content of the received updated data according to the signature extracted from the device. For example, assuming the signature comprises the checksum of the updated data&#39;s content, the mobile device  104  may compute the checksum of the content of the received updated data. The mobile device  104  may then compare between the computed checksum value and the checksum value extracted from the device identifier to verify the content. In another example, assuming the signature comprises the hash value computed based on the content of the updated data, the mobile device  104  may apply the (same) hash function(s) used by the wireless device  102  to compute the hash value based on the content of the received updated data. The mobile device  104  may then compare between the computed hash value and the hash value extracted from the device identifier to verify the content. 
     The mobile device  104  may analyze the updated data received from the wireless device and may generate one or more events based on the content of the updated data and/or based on analysis of the updated data. The mobile device  104  may be further configured to initiate one or more actions, for example, generate an indication, an alert, a notification and/or the like to notify the user(s)  108  of one or more of the events. 
     In particular, in case the wireless device  102  and the mobile device  104  are used to support one or more of the child safety applications and configured to collect sensory data from one or more pressure sensors  206  deployed in the child hosting apparatus, the mobile device  104  may generate one or more child safety related events based on the content of the updated data collected and received from the wireless device  102 . For example, assuming that based on analysis of the updated data, the mobile device  104  determines that a child is present (sitting) in a nearby child hosting apparatus, for example, a car child seat, the mobile device  104  may generate an event accordingly and may further generate an indication to the associated user  106  to indicate of the presence of the child in the nearby child seat. 
     The mobile device  104  may further generate one or more events based on the content of the updated data and/or its analysis combined with a distance from the wireless device  102  inferred from the ability or inability to detect the wireless device  102  via the wireless channel  106 . For example, assuming the wireless device  102  and the mobile device  104  are used to support one or more of the child safety applications, the mobile device  104  may generate one or more child safety related events based on the content of the updated data received from the wireless device  102  combined with the distance of the mobile device  104  from the wireless device  102 . For example, assuming that based on analysis of the data most recently received from the wireless device  102 , the mobile device  104  determines that a child is sitting in a nearby child hosting apparatus, for example, a car child seat. Further assuming that the mobile device  104  is no longer able to intercept the device identifier of the wireless device  102  which may be indicative that the wireless device  104  has moved out of the transmission range of the wireless device  102  and is hence located further than the certain distance, for example, 10 meters from the wireless device  102 . In such case the mobile device  104  may generate an event accordingly and may further generate an alert to the associated user  106  to indicate that the user  106  may be moving away and potentially leaving the child in the child seat. 
     After terminating the connection with the wireless device  102 , the mobile device  104  may branch back to  132  and continue probing the wireless channel  106  for one or more purposes, for example, detect a change in the device identifier of the wireless device  102 , detect leaving the transmission range of the wireless device  102 , detect one or more other wireless devices  102  and/or the like.
