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 safety device for a walker includes a distance measuring sensor for determining whether a user is at too far or too close distances relative to the front side of the walker. The sensor provides data to a CPU processor indicative of such events. The processor includes logic which analyzes such data and provides audial, visual and/or tactile stimuli to the user warning the user that he/she is at undesirable distances relative to the walker. The process logic can be modified so as to vary the type and/or frequency of warnings given to the user.

An improved wearable locator has an ultra-low power RF transceiver, GPS receiver, cellular network RF transceiver, processor, programmable non-volatile memory, LCD display, accelerometer and rechargeable battery. To ensure that the locator is within a perimeter, it can cooperate with a subordinate unit that includes an ultra-low power RF transceiver, processor, power supply, DC charging output, rechargeable battery, visual, audible and tactile enunciators and pushbutton, and can be plugged into an outlet or be unplugged and be mobile. Other wireless units can be used to define a perimeter.

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 alert system to assist in child safety in a vehicle includes a seat belt buckle insert adapted to be inserted between the male and female parts of a standard safety belt found in most automobiles or for a child car safety seat. It may also include a portable receiver device designed to be carried by a vehicle operator. The seat belt buckle insert detects whether the seat belt has been buckled and the temperature is within an acceptable range, as well as the approximate distance between the seat belt buckle insert and portable receiver device. The seat belt buckle transmits information gathered to the portable receiver device and triggers alerts notifying the vehicle operator of a child's safety status.

An anti-theft proximity alert system that includes a wearable smart charm with a charm housing having a button for the wearer to manually cancel a triggered sensory alert sequence. The object monitor may include within its housing a motion detector that monitors the state of motion of the object monitor, and at least one operating instruction that adjusts a property of the transmitted proximity signal in response to a change in the object monitor's motion state. A silent alarm of vibration and/or light on the charm housing perceptible to the wearer of the smart charm may be activated prior to the activation of an auditory alarm.

Systems and methods for detecting a breach of a proximity threshold associated with a first electronic device comprising a first electronic device configured to transmit a first wireless signal; and a second electronic device configured to: 1) measure a strength of the first wireless signal, 2) determine, based on the measured strength of the first wireless signal, a proximity of the second electronic device to the first electronic device, 3) instruct the first electronic device, via a second wireless signal, to subsequently transmit the first wireless signal at a predetermined interval corresponding with a proximity of the second electronic device to a proximity threshold associated with the first electronic device, and 4) measure a strength of the first wireless signal being transmitted at the predetermined interval to detect when the second electronic device breaches the proximity threshold associated with the first electronic device.

A method for detecting and presenting burnout symptoms associated with users is provided. The method may include receiving a plurality of predictor rules for monitoring and detecting a plurality of burnout indicators. The method may further include monitoring and receiving the plurality of burnout indicators. Additionally, the method may include storing the monitored and received plurality of burnout indicators. The method may also include detecting a plurality of burnout events associated with the stored monitored and received plurality of burnout indicators. The method may further include determining the plurality of burnout symptoms based on the detected plurality of burnout events. The method may also include determining at least one aggregate score based on the determined plurality of burnout symptoms. The method may further include presenting at least one alert and at least one recommendation based on the determined plurality of burnout symptoms and the determined at least one aggregate score.

There is provided a system for determining a sound source and a method thereof. The system comprises: an audio sensor; a biosensor for measuring one or more biosignals of a subject; and a processing unit communicatively coupled with the audio sensor and the biosensor, the processing unit configured to perform operations comprising: obtaining audio data from the audio sensor and biosignal data from the biosensor, the audio data and the biosignal data being time-synced with each other, detecting, based on the audio data, a sound exceeding a threshold, and determining that the sound exceeding the threshold originates from the subject if the biosignal data indicates a change in the one or more biosignals at a corresponding time.

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.
