BACKGROUND

The subject matter described herein relates generally to the field of electronic devices and more particularly to a vehicular heatstroke safety system.

There have been over 600 heatstroke deaths of children left in vehicles in the United States since 1998. Approximately half of such deaths are caused by a caregiver forgetting or otherwise leaving a child in a car seat. Accordingly, heatstroke safety systems may find utility.

DETAILED DESCRIPTION

Described herein are examples of a heatstroke safety systems and methods to implement combinable image input devices in electronic devices. In the following description, numerous specific details are set forth to provide a thorough understanding of various examples. However, it will be understood by those skilled in the art that the various examples may be practiced without the specific details. In other instances, well-known methods, procedures, components, and circuits have not been illustrated or described in detail so as not to obscure the particular examples.

As described above, it may be useful to provide a heatstroke safety system which may be used in vehicles. In some examples described herein a heatstroke safety system may comprise one or more smart sensors which may trigger one or more alerts. Smart sensors may collect data such as ambient temperature, concentration of elements such carbon-dioxide and/or carbon monoxide in the air, and accelerometer and/or location sensors to accurately determine whether a car is occupied and environmental conditions inside a vehicle or other structure in which humans or animals may reside. As used herein, the term vehicle should be construed broadly to include cars, trucks, ships, aircrafts, spacecrafts, trains, buses or any form of transportation in which humans or animals may reside. In the event occupancy is detected and potential heatstroke conditions are identified, a warning signal may cause an alert module to implement one or more alerts.

Further structural and operational details will be described with reference toFIGS. 1-10, below.

FIG. 1is a schematic illustration of a heatstroke safety system in accordance with some examples. In various examples, a heatstroke safety system may comprise an electronic device100comprising a plurality of sensors comprising at least one of a motion sensor110and a location sensor112. In some examples motion sensor110may be implemented using an accelerometer, magnetometer, orientation sensor, a gyrometer, or similar device. Location sensor112may be implemented using a proximity detector, cellular network identifier, a WiFi identifier, or a global navigation satellite system (GNSS) receiver, or similar device.

Electronic device100may further include a temperature sensor120, and one or more air quality sensors such as a carbon dioxide sensor122and/or a carbon monoxide sensor124.

Electronic device100may further include one or more communication interfaces130, e.g. a cellular interface132, a WiFi interface134, or Bluetooth interface136. Communication interfaces130may implement one or more wireless communication connections via a protocol such as, e.g., Bluetooth or 802.11X. IEEE 802.11a, b or g-compliant interface (see, e.g., IEEE Standard for IT-Telecommunications and information exchange between systems LAN/MAN—Part II: Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) specifications Amendment 4: Further Higher Data Rate Extension in the 2.4 GHz Band, 802.11G-2003). Another example of a wireless interface would be a general packet radio service (GPRS) interface (see, e.g., Guidelines on GPRS Handset Requirements, Global System for Mobile Communications/GSM Association, Ver. 3.0.1, December 2002).

Electronic device may further include a controller140communicatively coupled to the plurality of sensors. Electronic device210may further include one or more processors224and a memory module240. As used herein, the term “controller” means any type of computational element, such as but not limited to, a microprocessor, a microcontroller, a complex instruction set computing (CISC) microprocessor, a reduced instruction set (RISC) microprocessor, a very long instruction word (VLIW) microprocessor, or any other type of processor or processing circuit. In one example, controller140may be embodied as an Intel® Atom™ processors, Intel® Atom™ based System-on-a-Chip (SOC) or Intel® Core2 Duo® or i3/i5/i7 series processor available from Intel Corporation, Santa Clara, Calif., USA. Also, one or more processors from other manufactures may be utilized. Moreover, the processors may have a single or multi core design.

Electronic device100may further include a power source150(e.g., one or more batteries) and a power management module152comprising processing circuitry to monitor a power level of the power source and to generate a warning signal when the power level of the power source falls below a threshold.

The system may further include an alert module160. In the example depicted inFIG. 1alert module160comprises a controller162, which may be similar to controller140and one or more communication interfaces180, e.g. a cellular interface182, a WiFi interface184, or Bluetooth interface186. Alert module may comprise a an audible alarm170, e.g., a siren, whistle or the like, a visual alarm172, e.g., a strobe light, alarm light, or the like. Alert module160may further comprise a vibrator assembly174, e.g., an impact hammer or a vibrator, a window punch176and an actuator.

In some examples the alert module160may be physically integrated in a single housing with the electronic device100. In other examples the alert module160may be physically separate from the electronic device160and may be communicatively coupled to the electronic device100via the communication interfaces130,180. Further, communication interfaces130,180may provide communication capabilities to one or more remote devices via a network190. Example devices may include an emergency response service192, a mobile phone194, or a vehicle alarm196.

FIG. 2is a schematic illustration of a heatstroke safety system in accordance with some embodiments. In the example depicted inFIG. 2the electronic device100may be positioned in the cabin of a vehicle200, e.g., an automobile and the alert module may include a vibrator assembly174mounted elsewhere in the vehicle200, e.g., in engine bay, underneath the driver side seat, or in the trunk.

Having described various structural components of examples of a heatstroke safety system, operations implemented by the system will be described with reference toFIGS. 3-5. Referring first toFIG. 3, at operation310the electronic device100monitors sensor outputs. For example, the electronic device100may be positioned in the cabin of a vehicle200as depicted inFIG. 2and may monitor sensors such as the temperature sensor120, the carbon dioxide sensor122, and/or the carbon monoxide sensor124. Outputs from these sensors may be received by the controller140.

At operation315the controller may determine, based on inputs from at least one of the motion sensor110, the location sensor112, the temperature sensor120, or the air quality sensor122/124, whether a dangerous condition exists in a region proximate the electronic device100. By way of example, controller140may monitor air temperature and concentrations of carbon dioxide and/or carbon monoxide in the cabin. If the air temperature exceeds a threshold (e.g., 180 degrees) and/or the carbon dioxide level exceeds a threshold (e.g., 30,000 parts per million (ppm)) and/or the carbon monoxide level exceeds a threshold (e.g., 70 ppm) then a dangerous condition may be determined to exist in the cabin.

If, at operation315, the controller determines that a dangerous condition does not exist then control passes back to operation310and the controller140continues to monitor the sensor outputs. By contrast, if at operation315the controller140determines that a dangerous condition exists then control passes to operation320and the controller140generates a warning signal. In embodiments in which the alarm module160is physically separate from the electronic device100the warning signal may be transmitted (operation325) from one or more of the communication interfaces130on the electronic device100and, operation330, received in the alert module160via one or more of the communication interfaces180.

At operation335, in response to the warning signal generated by the controller140, the alert module160generates at least one of an audible alarm using the audible alarm module170, a visual alarm using the visual alarm module172, or a motion-based alarm using the vibrator assembly174, or combinations thereof. In some examples the alert module160may be configured to activate a siren or other audible alarm to alert persons proximate the vehicle that a dangerous condition exists in the vehicle. Further, the alert module160may be configured to generate a visual alarm such as a flashing light or the like. Further, the alert module160may be configured to active a vibration assembly such as the vibration assembly174depicted inFIG. 2. In such examples the vibration assembly174may vibrate portions of the vehicle with sufficient force to cause the vehicle's alarm system to activate.

At operation340, in response to the warning signal generated by the controller140, the alert module initiates a communication to a remote communication device. In some examples the remote communication device comprises an emergency response service192. In such examples the controller162in the alert module160may query the electronic device100to request a location from the location sensor112of the electronic device. The electronic device100may respond with a location indicator, e.g., a GPS coordinate, for the electronic device. The location indicator may be transmitted to the emergency response service in the communication from the alert module. Additional information, e.g., a make, model, description, and license plate number of the vehicle and contact information for an owner of the vehicle may also be included in the communication to the emergency response service to facilitate locating the vehicle and the vehicle's owner.

In further examples the remote communication device comprises a vehicle alarm194. By way of example, alert module160may be configured to communicate with the vehicle's security system to trigger the vehicle alarm.

In further examples the remote communication device comprises one or more mobile phones194. By way of example, alert module160may be configured to send a message (e.g., a text message) or place a phone call to a phone number, e.g., a phone belonging to the owner of the vehicle. In other examples the remote communication device may comprise a mobile service operator. In such examples the communication may include location data and/or vehicle description data as described above, and the mobile service operator may generate and transmit an emergency response message to mobile devices proximate to the location of the electronic device.

At operation345the alert module160activates one or more actuators. In some examples the actuators may comprise a vibrator assembly174which is configured to trigger a vehicle alarm, as described above. In another example the alert module160may be mounted to a vehicle window and may include a window punch176capable to break the vehicle window and an actuator178which, in response to the warning signal, forces the window punch176against the vehicle window. In such examples the alert module160may comprise a display to present data from at least one of the plurality of sensors. For example, the alert module may display a message on the display requesting help from persons proximate the vehicle.

In some examples the alert module160may implement series of escalating responses to different danger thresholds and/or lags in response times. For example, if a dangerous condition is detected an alarm may be triggered immediately. If there's no response to the alarm within a predetermined time period or if the dangerous condition worsens, then a call may be placed to emergency services. Again, if there's no response for a predetermined time period or if the dangerous condition worsens, then the window punch may be actuated to break the window.

In some examples the electronic device may utilize data from the motion sensor110, the location sensor112, and/or the carbon monoxide sensor to adjust a rate at which the controller140samples data from the various sensors on the electronic device. Referring toFIG. 4, at operation410the controller140monitors outputs of the motion sensor110and/or the location sensor112. Based on data from the motion sensor110and the location sensor112the controller140determines (operation415) whether the electronic device100is in motion or in a predetermined location known to be safe, or whether the vehicle is unoccupied (e.g., by determining the carbon dioxide content of the ambient air in the cabin).

If, at operation415, the controller makes a determination that the electronic device100is in motion, in a predetermined location, or unoccupied, then control passes to operation420and the controller140samples sensor data at a first sampling rate. By way of example, if the controller determines that the vehicle is in motion, in a predetermined location deemed to be safe, or is unoccupied then the controller may place the electronic device100in a low-power consumption mode in which the controller140reduces the sampling rate for sampling data from the sensors, thereby reducing power consumption by the electronic device100.

By contrast, if at operation415the controller makes a determination that the electronic device100is not in motion, in a predetermined location, or unoccupied, then control passes to operation420and the controller140samples sensor data at a second sampling rate. By way of example, if the controller determines that the vehicle is not in motion, in a predetermined location deemed to be safe, or is occupied then the controller may place the electronic device100in a normal power consumption mode in which the controller140increases the sampling rate for sampling data from the sensors. In some examples, the escalation of warnings and/or responses can also be adjusted depending on whether the vehicle is in motion, at a predetermined location, or unoccupied.

In further examples the electronic device may include a power source150and a power management module152to monitor a power level of the power source and to generate a warning signal when the power level of the power source falls below a threshold. Referring toFIG. 5, at operation510the power management module152may monitor a power level of the power source150. If, at operation515the power level of the power source150is below a threshold then control passes to operation520and the electronic device may generate a warning signal to indicate that the power source is low and needs to be replaced and/or recharged. The warning signal may be presented via the audible alarm170, the visual alarm172and/or the vibrator assembly174.

Thus, described herein are examples of a heatstroke safety system which may be used in enclosed environments such as vehicles. As described above, in some examples the electronic device may be embodied as a computer system.FIG. 6illustrates a block diagram of a computing system600in accordance with an example. The computing system600may include one or more central processing unit(s)602or processors that communicate via an interconnection network (or bus)604. The processors602may include a general purpose processor, a network processor (that processes data communicated over a computer network603), or other types of a processor (including a reduced instruction set computer (RISC) processor or a complex instruction set computer (CISC)). Moreover, the processors602may have a single or multiple core design. The processors602with a multiple core design may integrate different types of processor cores on the same integrated circuit (IC) die. Also, the processors602with a multiple core design may be implemented as symmetrical or asymmetrical multiprocessors.

A chipset606may also communicate with the interconnection network604. The chipset606may include a memory control hub (MCH)608. The MCH608may include a memory controller610that communicates with a memory612. The memory412may store data, including sequences of instructions, that may be executed by the processor602, or any other device included in the computing system600. In one example, the memory612may include one or more volatile storage (or memory) devices such as random access memory (RAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), static RAM (SRAM), or other types of storage devices. Nonvolatile memory may also be utilized such as a hard disk. Additional devices may communicate via the interconnection network604, such as multiple processor(s) and/or multiple system memories.

The MCH608may also include a graphics interface614that communicates with a display device616. In one example, the graphics interface614may communicate with the display device616via an accelerated graphics port (AGP). In an example, the display616(such as a flat panel display) may communicate with the graphics interface614through, for example, a signal converter that translates a digital representation of an image stored in a storage device such as video memory or system memory into display signals that are interpreted and displayed by the display616. The display signals produced by the display device may pass through various control devices before being interpreted by and subsequently displayed on the display616.

A hub interface618may allow the MCH608and an input/output control hub (ICH)620to communicate. The ICH620may provide an interface to I/O device(s) that communicate with the computing system600. The ICH620may communicate with a bus622through a peripheral bridge (or controller)624, such as a peripheral component interconnect (PCI) bridge, a universal serial bus (USB) controller, or other types of peripheral bridges or controllers. The bridge624may provide a data path between the processor602and peripheral devices. Other types of topologies may be utilized. Also, multiple buses may communicate with the ICH620, e.g., through multiple bridges or controllers. Moreover, other peripherals in communication with the ICH620may include, in various examples, integrated drive electronics (IDE) or small computer system interface (SCSI) hard drive(s), USB port(s), a keyboard, a mouse, parallel port(s), serial port(s), floppy disk drive(s), digital output support (e.g., digital video interface (DVI)), or other devices.

The bus622may communicate with an audio device626, one or more disk drive(s)628, and a network interface device630(which is in communication with the computer network603). Other devices may communicate via the bus622. Also, various components (such as the network interface device630) may communicate with the MCH608in some examples. In addition, the processor602and one or more other components discussed herein may be combined to form a single chip (e.g., to provide a System on Chip (SOC)). Furthermore, the graphics accelerator616may be included within the MCH608in other examples.

Furthermore, the computing system600may include volatile and/or nonvolatile memory (or storage). For example, nonvolatile memory may include one or more of the following: read-only memory (ROM), programmable ROM (PROM), erasable PROM (EPROM), electrically EPROM (EEPROM), a disk drive (e.g.,628), a floppy disk, a compact disk ROM (CD-ROM), a digital versatile disk (DVD), flash memory, a magneto-optical disk, or other types of nonvolatile machine-readable media that are capable of storing electronic data (e.g., including instructions).

FIG. 7illustrates a block diagram of a computing system700, according to an example. The system700may include one or more processors702-1through702-N (generally referred to herein as “processors702” or “processor702”). The processors702may communicate via an interconnection network or bus704. Each processor may include various components some of which are only discussed with reference to processor702-1for clarity. Accordingly, each of the remaining processors702-2through702-N may include the same or similar components discussed with reference to the processor702-1.

In an example, the processor702-1may include one or more processor cores706-1through706-M (referred to herein as “cores706” or more generally as “core706”), a shared cache708, a router710, and/or a processor control logic or unit720. The processor cores706may be implemented on a single integrated circuit (IC) chip. Moreover, the chip may include one or more shared and/or private caches (such as cache708), buses or interconnections (such as a bus or interconnection network712), memory controllers, or other components.

In one example, the router710may be used to communicate between various components of the processor702-1and/or system700. Moreover, the processor702-1may include more than one router710. Furthermore, the multitude of routers710may be in communication to enable data routing between various components inside or outside of the processor702-1.

The shared cache708may store data (e.g., including instructions) that are utilized by one or more components of the processor702-1, such as the cores706. For example, the shared cache708may locally cache data stored in a memory714for faster access by components of the processor702. In an example, the cache708may include a mid-level cache (such as a level 2 (L2), a level 3 (L3), a level 4 (L4), or other levels of cache), a last level cache (LLC), and/or combinations thereof. Moreover, various components of the processor702-1may communicate with the shared cache708directly, through a bus (e.g., the bus712), and/or a memory controller or hub. As shown inFIG. 7, in some examples, one or more of the cores706may include a level 1 (L1) cache716-1(generally referred to herein as “L1 cache716”).

FIG. 8illustrates a block diagram of portions of a processor core706and other components of a computing system, according to an example. In one example, the arrows shown inFIG. 8illustrate the flow direction of instructions through the core706. One or more processor cores (such as the processor core706) may be implemented on a single integrated circuit chip (or die) such as discussed with reference toFIG. 7. Moreover, the chip may include one or more shared and/or private caches (e.g., cache708ofFIG. 7), interconnections (e.g., interconnections704and/or112ofFIG. 7), control units, memory controllers, or other components.

As illustrated inFIG. 8, the processor core706may include a fetch unit802to fetch instructions (including instructions with conditional branches) for execution by the core706. The instructions may be fetched from any storage devices such as the memory714. The core706may also include a decode unit804to decode the fetched instruction. For instance, the decode unit804may decode the fetched instruction into a plurality of uops (micro-operations).

Additionally, the core706may include a schedule unit806. The schedule unit806may perform various operations associated with storing decoded instructions (e.g., received from the decode unit804) until the instructions are ready for dispatch, e.g., until all source values of a decoded instruction become available. In one example, the schedule unit806may schedule and/or issue (or dispatch) decoded instructions to an execution unit808for execution. The execution unit808may execute the dispatched instructions after they are decoded (e.g., by the decode unit804) and dispatched (e.g., by the schedule unit806). In an example, the execution unit808may include more than one execution unit. The execution unit808may also perform various arithmetic operations such as addition, subtraction, multiplication, and/or division, and may include one or more an arithmetic logic units (ALUs). In an example, a co-processor (not shown) may perform various arithmetic operations in conjunction with the execution unit808.

Further, the execution unit808may execute instructions out-of-order. Hence, the processor core706may be an out-of-order processor core in one example. The core706may also include a retirement unit810. The retirement unit810may retire executed instructions after they are committed. In an example, retirement of the executed instructions may result in processor state being committed from the execution of the instructions, physical registers used by the instructions being de-allocated, etc.

The core706may also include a bus unit714to enable communication between components of the processor core706and other components (such as the components discussed with reference toFIG. 8) via one or more buses (e.g., buses804and/or812). The core706may also include one or more registers816to store data accessed by various components of the core706(such as values related to power consumption state settings).

Furthermore, even thoughFIG. 7illustrates the control unit720to be coupled to the core706via interconnect812, in various examples the control unit720may be located elsewhere such as inside the core706, coupled to the core via bus704, etc.

In some examples, one or more of the components discussed herein can be embodied as a System On Chip (SOC) device.FIG. 9illustrates a block diagram of an SOC package in accordance with an example. As illustrated inFIG. 9, SOC902includes one or more processor cores920, one or more graphics processor cores930, an Input/Output (I/O) interface940, and a memory controller942. Various components of the SOC package902may be coupled to an interconnect or bus such as discussed herein with reference to the other figures. Also, the SOC package902may include more or less components, such as those discussed herein with reference to the other figures. Further, each component of the SOC package902may include one or more other components, e.g., as discussed with reference to the other figures herein.

As illustrated inFIG. 9, SOC package902is coupled to a memory960(which may be similar to or the same as memory discussed herein with reference to the other figures) via the memory controller942. In an example, the memory960(or a portion of it) can be integrated on the SOC package902.

The I/O interface940may be coupled to one or more I/O devices970, e.g., via an interconnect and/or bus such as discussed herein with reference to other figures. I/O device(s)970may include one or more of a keyboard, a mouse, a touchpad, a display, an image/video capture device (such as a camera or camcorder/video recorder), a touch surface, a speaker, or the like.

FIG. 10illustrates a computing system1000that is arranged in a point-to-point (PtP) configuration, according to an example. In particular,FIG. 10shows a system where processors, memory, and input/output devices are interconnected by a number of point-to-point interfaces. As illustrated inFIG. 10, the system1000may include several processors, of which only two, processors1002and1004are shown for clarity. The processors1002and1004may each include a local memory controller hub (MCH)1006and1008to enable communication with memories1010and1012.

In an example, the processors1002and1004may be one of the processors702discussed with reference toFIG. 7. The processors1002and1004may exchange data via a point-to-point (PtP) interface1014using PtP interface circuits1016and1018, respectively. Also, the processors1002and1004may each exchange data with a chipset1020via individual PtP interfaces1022and1024using point-to-point interface circuits1026,1028,1030, and1032. The chipset1020may further exchange data with a high-performance graphics circuit1034via a high-performance graphics interface1036, e.g., using a PtP interface circuit1037.

The chipset1020may communicate with a bus1040using a PtP interface circuit1041. The bus1040may have one or more devices that communicate with it, such as a bus bridge1042and I/O devices1043. Via a bus1044, the bus bridge1043may communicate with other devices such as a keyboard/mouse1045, communication devices1046(such as modems, network interface devices, or other communication devices that may communicate with the computer network1003), audio I/O device, and/or a data storage device1048. The data storage device1048(which may be a hard disk drive or a NAND flash based solid state drive) may store code1049that may be executed by the processors1004.

In Example 19, the subject matter of any one of Examples 16-18 can optionally include processing circuitry to sample data from at least one of temperature sensor, or the air quality sensor at a second sampling rate, different than the first sampling rate, in response to a determination that the controller is not in motion or is in a second predetermined location.

Example 20 is a non-transitory machine readable medium comprising instructions which, when executed by a controller, configure the controller to determine, based on inputs from at least one of a motion sensor, a location sensor, a temperature sensor, or an air quality sensor, whether a dangerous condition exists in an enclosed space proximate the controller and in response to a determination that a dangerous condition exists in a region proximate the controller, to generate a warning signal

In Example 21, the subject matter of Example 20 can optionally include instructions which, when executed by a controller, configure the controller to determine, based on an input from at least one of the motion sensor or the location sensor, whether the controller is in motion or in a first predetermined location, and in response to a determination that the controller is in motion or in a first predetermined location, to place an electronic device in a low-power consumption mode.

In Example 22, the subject matter of any one of Examples 20-21 can optionally include instructions which, when executed by a controller, configure the controller to sample data from at least one of the temperature sensor, or the air quality sensor at a first sampling rate in response to a determination that the controller is in motion or in a first predetermined location.

In Example 23, the subject matter of any one of Examples 20-22 can optionally include instructions which, when executed by a controller, configure the controller to sample data from at least one of temperature sensor, or the air quality sensor at a second sampling rate, different than the first sampling rate, in response to a determination that the controller is not in motion or is in a second predetermined location.

The terms “logic instructions” as referred to herein relates to expressions which may be understood by one or more machines for performing one or more logical operations. For example, logic instructions may comprise instructions which are interpretable by a processor compiler for executing one or more operations on one or more data objects. However, this is merely an example of machine-readable instructions and examples are not limited in this respect.

The terms “computer readable medium” as referred to herein relates to media capable of maintaining expressions which are perceivable by one or more machines. For example, a computer readable medium may comprise one or more storage devices for storing computer readable instructions or data. Such storage devices may comprise storage media such as, for example, optical, magnetic or semiconductor storage media. However, this is merely an example of a computer readable medium and examples are not limited in this respect.

The term “logic” as referred to herein relates to structure for performing one or more logical operations. For example, logic may comprise circuitry which provides one or more output signals based upon one or more input signals. Such circuitry may comprise a finite state machine which receives a digital input and provides a digital output, or circuitry which provides one or more analog output signals in response to one or more analog input signals. Such circuitry may be provided in an application specific integrated circuit (ASIC) or field programmable gate array (FPGA). Also, logic may comprise machine-readable instructions stored in a memory in combination with processing circuitry to execute such machine-readable instructions. However, these are merely examples of structures which may provide logic and examples are not limited in this respect.

Some of the methods described herein may be embodied as logic instructions on a computer-readable medium. When executed on a processor, the logic instructions cause a processor to be programmed as a special-purpose machine that implements the described methods. The processor, when configured by the logic instructions to execute the methods described herein, constitutes structure for performing the described methods. Alternatively, the methods described herein may be reduced to logic on, e.g., a field programmable gate array (FPGA), an application specific integrated circuit (ASIC) or the like.

In the description and claims, the terms coupled and connected, along with their derivatives, may be used. In particular examples, connected may be used to indicate that two or more elements are in direct physical or electrical contact with each other. Coupled may mean that two or more elements are in direct physical or electrical contact. However, coupled may also mean that two or more elements may not be in direct contact with each other, but yet may still cooperate or interact with each other.

Reference in the specification to “one example” or “some examples” means that a particular feature, structure, or characteristic described in connection with the example is included in at least an implementation. The appearances of the phrase “in one example” in various places in the specification may or may not be all referring to the same example.
