A child tracking system includes an electronic device that may be manipulated. A pair of tracking units is provided. Each of the tracking units may be worn by an associated one of an adult and a child. Each of the tracking units may be in communication with a global positioning satellite. Thus, a physical location corresponding to each of the tracking units may be identified. Each of the tracking units is in electrical communication with the electronic device. Thus, the electronic device may display the physical location corresponding to each of the tracking units. Each of the tracking units has a fingerprint reader to read fingerprints.

Example techniques of this disclosure are directed determining one or more values that represent a monitoring attribute for one or more body-worn tracking devices (BWTDs). In some instances, the techniques include determining a compliance metric that represents a level of compliance for at least one offender. That is, the compliance metric may be a quantitative value that represents whether a user wearing BWTD is complying with established rules or desired behaviors.

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.

A separation alert device for warning a user of separation from an item includes a housing that defines an internal space. The housing is configured for retention on the user's person. A power module, a microprocessor, a first proximity sensor and a plurality of alarms are coupled to the housing and are positioned in the internal space. The microprocessor is operationally coupled to the power module. The first proximity sensor and the alarms are operationally coupled to the microprocessor. A second proximity sensor is in wireless communication with the microprocessor. The second proximity sensor is coupled to an item that the user desires to retain proximate to the user. The microprocessor is positioned to receive a location signal from the second proximity sensor. Separation of the first proximity sensor by a preset distance from the second proximity sensor will compel the microprocessor to compel the alarms to notify the user.

A safety system comprised of safety devices each worn by a caretaker and up to three people requiring minding, that alerts using color coded LED lights and audible tones when a monitored person is in danger. The device alerts if the person is beyond a preset distance, is close to or is in a body of water, or signals they are in trouble, using phased-array radar coupled with image processing.

The phased-array radar allows the remote sensing of water in either daylight or night. The phased-array radar comprises multiple antenna elements including an independent antenna element phase shifter allowing beamsteering. The device scans an object using a preset beamsteering algorithm independent of movement. The multiple antenna elements and beamsteering improve image data accuracy which is then interpreted and correlated with a body of water characteristics. The phased-array radar is also used for caretaker-monitored person communications.

An apparatus alerts on a distance between items. The apparatus includes a radio for communicating with an internet of things (IoT) tag on an item. A locator module determines a distance between two or more items, and an alertor module alerts a user to a violation of a proximity rule.

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.

This disclosure relates to systems and methods for summoning emergency personnel to assist a user associated with a portable device. A system can include a processor that can access non-transitory memory and execute machine readable instructions stored therein. The machine readable instructions can cause the processor to receive an assistance request generated by the portable device. The request can include location information for the portable device. The machine readable instructions can further cause the processor to transmit an assistance summons request to one or more selected devices that the user is need of assistance, receive a confirmation message generated by at least one of the one or more selected devices confirming that the user associated with the portable device is need of the assistance, and transmit one or more notification messages to summon the emergency personnel for the user.

A system and associated equipment are provided to facilitate social distancing. The system issues alarms when the distance between a user and an object is at or below a social distancing threshold. The system enables trade-offs between risk and a desire to have in-person interaction for different activities by using one or more variable social distancing thresholds that may be based on social distancing guidelines and user characteristics.
