Abstract: A sensor-enabled tamper-resistant body-worn monitoring cuff that includes a magnet and a magnetic sensor that are adjacent to each other when the cuff is worn by an individual and are separated when the cuff is removed. The magnetic sensor detects a magnetic field of the magnet and causes an alert message to be wirelessly transmitted when the magnetic field drops below a predetermined threshold. The cuff further includes a physiological sensor, such as a heartrate sensor, and an inertial sensor, such as an accelerometer, which detect signals that are analyzed to determine whether the individual's physiological parameters have deviated from normal or expected values and which may cause an alert message to be wirelessly transmitted.

Abstract: A novel tool and process, primarily useful for assisting ice climbers in creating a “V-thread” anchor.
