Abstract: A device may include a communication interface and processing logic. The processing logic may be configured to receive messages from each of a number of locator devices. Each message may include a signal strength value associated with a test message transmitted by an other one of locator devices. The processing logic may also be configured to determine whether a current signal strength value received in a message from a first one of the plurality of locator devices is within a predetermined range associated with signal strength values included in messages received from the first locator device.

Abstract: A device may include a communication interface and processing logic. The processing logic may be configured to receive a signal from a wearable device, determine a signal strength of the received signal and receive, via the communication interface, messages from a plurality of other devices that received the signal. Each message may include a signal strength value corresponding to a signal strength measured by one of the plurality of other devices. The processing logic may further be configured to determine whether the device received the signal with a greatest signal strength, and transmit, via the communication interface and in response to determining that the device received the signal with the greatest signal strength, a message to a monitoring device indicating an identifier (ID) of the wearable device and a location of the device or an ID associated with the device.

Abstract: A computerized system and method for the design, execution and tracking of exercise programs including portable microprocessor controlled data controllers to instruct and record the actual computed workout for the user. A data communication link transfers data between the data controllers and a computer hosting application software and database files for the particular user, exercise and exercise regimen to create and display a customizable and comprehensive exercise system designed for the particular user.
