Abstract: A system and method of monitoring and resetting a protected device includes sensing a current flowing to a protected device over a time period and comparing the current flowing to the protected device over the time period. When the current flowing to the protected device over the time period differs from an expected power profile for the protected device, power going to the protected device is interrupted for an interval.

Abstract: A system and method of determining/checking the number of times an inmate in a correctional facility traverses the food line includes the inmate wearing a body-worn device. In some embodiments, the body-worn device includes location detection so that a location of the inmate is constantly monitored and when the inmate traverses the food line more than an allotted number of times (e.g., one time), an alert is generated. In other embodiments, the body-worn device includes an identification device (e.g., an RFID or a low-power transmitter), such that the body-worn device is detectable by detection devices positioned in the food line of the correctional facility and when the inmate traverses the food line more than once (or more than an allowed number of times) an alert is generated.

Abstract: A method of detecting and disabling offending devices includes monitoring for a radio frequency signal. When an offending device initializes and registers with a cell tower, it emits the radio frequency signal. After the radio frequency signal is detected, a message including an identification of the radio frequency signal is transmitted to a receiver of a base station. Responsive to receiving the message, the base station sends a secure transaction that includes an indication of the radio frequency signal to a processor of a cellular carrier system. Responsive to receiving the secure transaction, the processor of the cellular carrier system correlates a time and the radio frequency signal with an account associated with the registration of the offending device, disconnects the offending device and/or disables an account associated with the offending device.

Abstract: A method and apparatus of detecting life in a wearer of a body-worn device includes at least a temperature sensor and a motion sensing device (e.g., an accelerometer) interfaced or within the body-worn device, each coupled to the wearer of the body worn device to measure body temperature of the wearer as well as movement of the wearer. Further sensors such as heart beat sensors are also anticipated for improved accuracy. The method and apparatus of detecting life declares that the wearer is dead after successive periodic readings of temperature have continually changed at a predetermined rate and no movement has been detected by the motion sensing device for a predetermined period of time. In some embodiments, the motion sensing device is a three-axis accelerometer.
