A system for distinguishing an individual having an abnormal body temperature includes an interface module receiving a visible light image and a thermal image, a determining module executing an image analysis process on the visible light image to recognize an individual in the visible light image and to determine position data of the individual, and a processing module obtaining a temperature value corresponding to the individual from the thermal image according to the position data. The processing module further determines whether the temperature value falls within a predetermined range of abnormal body temperature, and outputs a warning signal when it is determined that the temperature value falls within the predetermined range of abnormal body temperature.

Embodiments of the present disclosure disclose a fall-off detection method for a wearable device and a wearable device. The method includes collecting physiological parameter information and activity information of a wearer of the wearable device; when an abnormality is detected in the physiological parameter information of the wearer of the wearable device and a time of the abnormality exceeds a preset time, determining that the wearable device falls off from the wearer; when it is determined that the wearable device falls off from the wearer, determining, according to the collected physiological parameter information and activity information of the wearer of the wearable device, a scenario mode that the wearer is in; and sending, according to the scenario mode that the wearer is in, an indication corresponding to the scenario mode.

A wearable device and a system for tracking the wearable device may enhance safety and peace of mind for a parent or caretaker of a child or other individual. The system may include a computing device, such as a smartphone, executing an application that provides alerts based on a distance between the computing device and the wearable device exceeding a threshold distance, based on the wearable device crossing a define geographic boundary, or one or more similar triggers. The wearable device may include an input button that allows a user of the wearable device to send a signal to the computing device of the parent or caretaker. An alert on the computing device might be disabled by pressing the input button on the wearable device.

A system for detecting the presence of an occupant in a child seat is provided. The system includes at least two sensor modules positioned to detect acceleration of the child seat. The sensor modules provide signals representative of the acceleration detected at the first and send sensor modules to a controller. The controller includes signal processing circuitry for processing the signal to determine whether the signals received from the sensor modules are representative of the physiological motion of the occupant. The controller processes the signals received from the sensor modules to isolate acceleration of the child seat from the motion of the vehicle.

A wearable device, a non-transitory computer readable recording medium that stores a control program, and a control method are disclosed. A wearable device comprises a belt and a processor. The belt is to be fastened to a body. The processor determines whether the wearable device is removed from the body. The processor notifies another device of removal of the wearable device from the body when determining the removal.

A wearable device and a system for tracking the wearable device may enhance safety and peace of mind for a parent or caretaker of a child or other individual. The system may include a computing device, such as a smartphone, executing an application that provides alerts based on a distance between the computing device and the wearable device exceeding a threshold distance, based on the wearable device crossing a define geographic boundary, or one or more similar triggers. The wearable device may include an input button that allows a user of the wearable device to send a signal to the computing device of the parent or caretaker. An alert on the computing device might be disabled by pressing the input button on the wearable device.

A wearable combination drowning prevention and soothing device is operable in either a drowning prevention mode or a soothing mode. In the drowning prevention mode the device monitors a wearer's heart rate and a moisture sensor to determine when, and how long, the device is submerged. Upon occurrence of a condition of those parameters meeting a predefined state consistent with distress, the device transmits an alert signal to an associated mobile device. In the soothing mode the device likewise monitors the wearer's heartrate as well as movements, and upon an indication in those monitored parameter that the wearer may be agitated, the device plays selected audio over a speaker of the device in an attempt to soothe the wearer.

Apparatus and methods are described, including apparatus for use with a subject who shares a bed with a second person. A motion sensor detects motion of the subject and motion of the second person, and generates a motion signal in response thereto. A control unit identifies components of the motion signal that were generated in response to motion of the subject, by distinguishing between components of the motion signal that were generated in response to motion of the subject, and components of the motion signal that were generated in response to motion of the second person. The control unit analyzes the components of the motion signal that were generated in response to motion of the subject and generates an output in response thereto. Other applications are also described.

The technology relates to portable personal monitor device and associated methods. In particular, the technology provides for improving the capability of personal monitor device systems by enabling functions such as two-way communications from the personal monitor; associating possible threats with one or more locations; and dynamically determining safe locations and potential evacuation routes. Also described herein are monitors which improve the detection of possible threats or risks by allowing a base unit to be used with various replacement sensor modules.

The present disclosure provides details of a system and method for a communication device for guards in controlled environments. The communication device is established based on an indoor wireless infrastructure in the controlled environment, receiving wireless positioning signals to calculate and determine the real-time location of a user carrying the device. The indoor wireless positioning can be combined with other available positioning methods to provide highly accurate positioning information of the guard. The communication device detects, monitors, and records activities of the guard during a period of time, and is controlled by the control center. The control center and the communication device respond quickly to different abnormal situations. In addition, the communication device detects contraband electronic devices and monitor surroundings of the guard. Thus, the disclosed system and method for the communication device provides improved communication and monitoring for guards in a controlled environment.
