## Background
BACKGROUND
The present disclosure relates to close range monitoring, and more specifically, to close range data exchange for safety monitoring.
Wireless technology may exist to exchange data over short distances. In some cases, this data may be exchanged from fixed or mobile devices using short-wavelength radio waves. Based on settings, these wireless signals may range anywhere from under one meter to over 100 meters. Many mobile devices such as smart phones may have a range of approximately 10 meters in any direction.
Wearable technology, or “wearables” may be clothing or accessories which incorporate computer and advanced electronic technologies. The wearables are often designed to incorporate practical functions and feature. For example, “activity trackers” can be used to monitor the activity level of a particular user, based on, for example, steps taken or a monitored heart rate. Wearables may also be used to improve child safety, where the technology may be worn by a child to monitor his or her activity or location, in order to avoid a dangerous situation.

DETAILED DESCRIPTION
Aspects of the present disclosure relate to close range monitoring, more particular aspects relate to close range data exchange for safety monitoring. While the present disclosure is not necessarily limited to such applications, various aspects of the disclosure may be appreciated through a discussion of various examples using this context.
In embodiments, a user device such as a smart phone may possess short-range wireless network capabilities through the use of, for example, a BLUETOOTH application. The device may then be paired with second short-range wireless network (e.g., BLUETOOTH) enabled device. This second device could be a wearable device or a clip, for example a pedometer, heart rate monitor, smart watch, or a simple BLUETOOTH-enabled clip. For ease of discussion, this second device will be referred to as a “wearable” herein. For example, the wearable may be attached to a child's clothing or wrist. The user device and the wearable may exchange data while paired over the network. At some point, the wearable or the smart phone may be out of range (e.g., of the short-range wireless connection or BLUETOOTH network). This may result in the disconnection of the user device with the wearable, and thus the cessation of data transfer between the wearable and the user device. This disconnection can be recognized by a system (for example, a computer system that may be embodied within the user device), and in response to the recognition, an audible alert can be by the user device. In embodiments, safety parameters, including temperature for a duration of time (e.g., a combination of a temperature parameter and a timing parameter), the presence of moisture, or other parameters which may indicate an unsafe condition based on the context of the user of the user device and the wearable, and may generate an alarm on the user device.
In embodiments, the wearable may have one or more sensors, in addition to possessing short-range wireless network capabilities. For example, the wearable could have a temperature sensor to detect the temperature of the environment surrounding the wearable or to detect the temperature of the individual in possession of the wearable. The wearable could also have a moisture sensor or sensors, which could be used to detect the presence of water at the location of the wearable. Various configurable parameters could be set to define, based on the user, environment, and intent of use, a set of unsafe conditions, as determined based on sensor data. For example, a detection of a temperature below 65° F. or above 75° F. could meet a safety parameter, which could indicate to the user that the wearable is in an unsafe condition. The safety parameter could also factor time into its determination, for example, by requiring that the sensor detect a particular temperature for a certain period of time in order to meet a safety alert parameter.
FIG. 1 depicts a system diagram of a system 100 for alerting a user to an unsafe condition over a short-range wireless network connection 112, according to embodiments. A computer system 102 may comprise a number of engines 104-110. The actions performed by the engines may be executed by one or more processors, for example, the processors of computer system 600 of FIG. 6. In embodiments, the computer system 102 may be embodied in a user device such as a smart phone, tablet, laptop computer, or device. The computer system 102 may be connected to a wearable device or “wearable” 116 via a wireless network connection 112. The network connection 112 may be a short-range wireless connection, for example, a BLUETOOTH network.
In embodiments, the network connecting engine 104 may detect a wearable 116 is within range of the network connection 112. The network connecting engine 104 may then connect with the wearable 116 by “pairing” with it over the short-range wireless connection 112. The wearable 116 may have one or more sensors 118a and 118b. In embodiments, these sensors 118 may be temperature sensors, moisture sensors, or other sensors. The sensors 118 may be installed on, as a part of, the wearable or they may communicatively coupled to the wearable.
Upon establishing a connection with the wearable 116, the wearable 116 may begin to send sensor data to the computer system 102. In embodiments, this can be a consistent transmission of sensor data from the wearable 116 to the computer system 102. This data can be received by the data receiving engine 106 of the computer system 102. In embodiments, the computer system 102 can also send data to the wearable 116. This data can be sent by the data receiving engine 106, or by another engine.
Based on the data received from the sensors 118 or the wearable 116, the computer system 102 may determine that a safety alert parameter has been met. In embodiments, the safety alert parameter may be one of a set of parameters ranging from temperature extremes determined unsafe and configured by a user or system administrator to the presence of moisture for a predetermined period of time. In embodiments, the absence of data transmission between the wearable 116 and the computer system 102 may meet a safety alert parameter, as the cessation of data transmission may indicate that the wearable 116 and the computer system 102 are no longer connected over the short-range wireless connection 112. In embodiments, the network connecting engine 104 of the computer system 102 could detect that the computer system 102 is no longer connected to the wearable 116 over the wireless network 112.
In embodiments, this could indicate that the wearable 116, and thus the user of the wearable, has moved outside of the short-range wireless connection 112 or BLUETOOTH range of connectivity. In embodiments, this disconnection could indicate an unsafe condition for the user of the wearable. For example, the wearable 116 may be worn by a child at a playground, and the computer system 102 could be embodied in a smartphone owned by a parent of the child. The child may be safe playing near the parent, but upon reaching a distance outside the close range BLUETOOTH network, or approximately 30 feet, the wearable will disconnect from the smart phone, indicating that the child is beginning to wander too far from the parent in possession of the previously paired smart phone.
In embodiments, once the determining engine 108 has determined that a particular safety alert parameter has been met, for example, an unsafe temperature as detected from the sensor data, the generating engine 110 of the computer system 102 may generate an audible alarm. In embodiments, the computer system 102 embodied in a smart phone may generate a tone or other alarm. In embodiments, the disconnection of the computer system 102 from the wearable 116 may also cause the wearable to alert the user via the generation of an alarm.
FIG. 2 depicts a system diagram of a system 200 for alerting a user of a wearable to an unsafe condition, according to embodiments. Like elements may correspond to like elements with those in FIG. 1.
A user device 202 could be, for example, a smartphone. This smartphone could embody a computer system, for example, computer system 102 of FIG. 1. The user device 202 could be connected to a wearable 206, over a network 204, such as a BLUETOOTH or short-range wireless connection. In embodiments, the wearable could be the wearable 116 of FIG. 1. The wearable 206 could have a set of sensors 208. These sensors could be configured to detect various environmental changes. For example, sensor 208a could detect environmental temperature, and sensor 208b could detect the presence of moisture. In embodiments, the wearable 206 could also comprise a variety of engines, which could execute on, for example, a computer processing circuit, instructions regarding detecting for unsafe conditions and alerting a user accordingly.
In embodiments, the wearable 206 could detect a user device 202 within a short-range wireless connection 204. The wearable could connect with the user device 202. In embodiments, this connecting of the wearable 206 and the user device 202 may occur automatically (i.e., without further user intervention) upon the user device 202 entering the short-range wireless connection (or BLUETOOTH network) range for the wearable. In other embodiments, the wearable 206 may prompt a user to connect to the user device 202. For example, if the user device 202 is recognized by the wearable 206, as one that has paired in the past, the wearable 206 could connect automatically, while an unrecognized user device 202 may prompt a user and require further confirmation, a password, or other confirmation of connection.
In embodiments, and upon establishing connection with the user device 202, a parameter receiving engine 212 of the wearable 206 may begin collecting, from the set of sensors on the wearable, environment data. This environment data can vary, depending on the type of wearable 206 as well as the types of sensors 208 installed on the wearable 206. Also upon establishing connection, a parameter receiving engine 212 of the wearable 206 may begin to receive, from the user device 202, safety alert parameter data. In embodiments, this safety parameter alert data may be a set of parameters for determining that a condition is unsafe. For example, these parameters may include particular temperatures that are unsafe for a child or a pet. The parameters may also include a particular period of time at which the temperatures must be sustained at the sensor or sensors. In embodiments, a safety alert parameter engine 214 may processes these parameters and compare them with the environment data captured by the sensors. In embodiments, the environment data and the safety parameter alert data may be stored on the wearable 206. In embodiments, the environment data may be transmitted to the user device 202, for storage. In embodiments, the safety parameter alert data may be set based on user input to the user device, stored on the user device 202, and transmitted to the wearable 206.
The safety alert parameter engine 214 can then determine, based on a comparison between the processed environment data and the safety parameter alert data, that a safety alert parameter has been met. In embodiments, an alarm may be generated by the wearable in response to this determination. For example, sensors 208a and 208b could each detect that it is in the presence of moisture. The safety alert parameter engine 214 can compare this environment data (presence of moisture) with a safety parameter received from the user device 202, and determine that a safety alert parameter has been met. In embodiments, an alarm can then be generated by the wearable. In some cases, this generation could include the transmission of a signal to a speaker on the wearable to cause the wearable to play a tone or an alarm. In other instances, this could generate a signal that may be transmitted across the network 204, if still connected, to cause the user device 202 to sound an audible alarm (via, for example, speakers on a smartphone). In embodiments, the safety alert parameter engine 214 may detect that it is no longer connected to the user device 202 over the short-range wireless connection 204. This may cause the wearable 206 to generate an audible alarm, indicating, for example, the wearable 206 is no longer within a safe distance of the user device 202. For example, in a public park, the range of the short-range wireless connection could be considered a safe distance between a child and his parent.
FIG. 3 depicts a block diagram of a use case for generating an alert based on network connectivity, according to embodiments. The figure depicts a user device 302 in various states of connectivity with a wearable 304, and the resulting states of each of the user device 302 and wearable 304, based on connectivity and/or sensor data. In embodiments, the user device 302 may be the same as the user device 202 of FIG. 2, or a device on which the computer system 102 of FIG. 1 may be embodied. In embodiments, the wearable 304 may be the wearable 206 of FIG. 2 or the wearable 116 of FIG. 1.
The user device 302a connected, via a BLUETOOTH link, to a wearable 304a. In this case, the connected user device 302a is in a “normal” state (i.e., non-alarm state), as is the wearable 304a. The two devices may have paired over the BLUETOOTH network and may now be able to transmit data, receive data, or both.
The user device 302b is disconnected from the wearable 304b. In this case, the disconnection may have occurred via a disrupted BLUETOOTH link, which could be resultant from one of the wearable 304b or the user device 302b moving outside of the BLUETOOTH range. Upon disconnection, the user device 302b and the wearable 304b, may both move to “abnormal” state (i.e., sounding an audible alarm). In embodiments, the disconnection may result in only one of the user device 302 or the wearable 304 moving to an abnormal state. However, as indicated by the use case of user device 302b and wearable 304b, both may sound an alarm upon disconnection. The detection of the disconnection and the generation of the alarm may occur as described herein.
The user device 302c and the wearable 304c may then reconnect, following, for example, the disconnection described at user device 302b and wearable 304b. The user device 302c and the wearable 304c may each return to a normal, non-alarm state. In embodiments, as depicted herein, the return to normal state may be facilitated by the reestablishment of the BLUETOOTH or other network reconnection between the user device 302c and the wearable 304c. In embodiments, the return to normal state can also occur via input from a user at the user device 302c or the wearable 304c. For example, in response to the alarm sounding, due to a disruption in the BLUETOOTH connection of user device 302b and wearable 304b, a user could notice that his child has wandered too far away. In response, the user could then disable the alarm via a swipe or tap on a screen of the user device 302b, causing a return to the normal state, as in user device 302c. 
While still connected to the user device 302d, over for example, a BLUETOOTH network, the wearable 304d could determine, based on for example, environment data obtained from sensors on the wearable, that an unsafe temperature has been reached at the wearable (for example, based on the determination that a safety alert parameter has been met). The determination could be made as described in, for example, FIGS. 1 and 2. In embodiments, this determination could cause the generation of an audible alarm that could cause one or both of the wearable 304d and the user device 302d to move from a normal state to an abnormal, alarm state.
FIG. 4 depicts a flow diagram of a method 400 for alerting a user of a user device, according to embodiments. The method 400 may be performed by a computer system, for example computer system 102 of FIG. 1, and for purposes of description of the figure may be embodied as a user device, such as a smart phone. The method 400 may begin at 402 when the user device connects to the wearable over a short-range wireless connection. Once connected, the user device may receive sensor data from the wearable, per 404. As described herein, this sensor data may include data collected from sensors on or in communication with the wearable. The user device may then determine that a safety alert parameter has been met, per 406. In embodiments, the determining may include detecting a set of temperature data in the received sensor data, and comparing with a threshold temperature the set of temperature data. The threshold temperature may be a type of safety alert parameter. Based on the comparing, the system can determine that the temperature at the wearable exceeds the threshold temperature, and may thus be an unsafe temperature. In embodiments, the unsafe temperature may be determined based on a temperature unsafe for a child, for a pet, or for another relevant reason.
In embodiments, the device may generate a first audible alarm based on the determination, per 408. In embodiments, the user device may also display the alarm notification via a text-based alert, an image, a photograph, a combination of these elements, or in another way suitable for alerting the user. The system may also generate metadata which may indicate that the particular safety parameter has been met. The system may then transmit the metadata, to the wearable, to generate a notification that a safety alert parameter has been met. In embodiments, this can include an alarm as described for the user device. The notification could also indicate the particular type of safety alert parameter that has been met. For example, in response to sensor data from a temperature sensor on the wearable, the device can generate an alarm as well as a notification and transmit a notification that the wearable that the alarm is sounding based on an unsafe temperature. The device may also determine that the user device has been disconnected from the wearable, per 410. Based on this disconnection, the user device may then generate an audible alarm, per 412.
FIG. 5 depicts a flow diagram of a method 500 for alerting a user of a wearable, according to embodiments. The method 500 may be carried out over a wearable, for example, wearable 206 of FIG. 2. The wearable may detect a user device within range of, for example, a short-range wireless connection, per 502. The wearable may then connect with the user device, per 504. Throughout its use, the wearable may collect environment data from sensors on or associated with it, per 506. The wearable may also receive safety alert parameter data from the user device, per 508. In embodiments, the user device could send the wearable data input by a user of the device (e.g., a smartphone user) regarding safety parameters for which the user was concerned. In embodiments, these parameters could vary based on the type and function of the wearable, the intended user of the wearable, or other parameters. Using the parameters and the environment data, the wearable may determine that a safety parameter has been met, and in response, the wearable may generate an alarm, per 510. In embodiments, a different alarm may be generated for each safety parameter. For example, if an alarm is triggered based on water exposure, a particular tone may sound, while an alarm based on temperature could trigger a different alarm. Notification of the safety alert parameter similar to those described at FIG. 4 may also originate at the wearable and be transmitted over the wireless connection to, for example, a user device in which the computer system (for example, the computer system 102 of FIG. 1) is embodied. A wearable may also detect when it has become disconnected from the user device over the wireless network. In embodiments, this disconnection may indicate that the wearable and the user device are too far apart to be connected by the short-range wireless (e.g., BLUETOOTH) connection. This disconnection may cause the wearable to generate an alarm, per 512.
