A wrist watch device which consists of a radial frequency (RF) emitter also comprises a vibrational sensor to detect movement which may be activated in the event of emergency

摘要

An emitter for emitting a warning or an emergency signal. The signal emitter comprises a watch type housing (80) having a fastening strap (90) or the like for securing or attaching the housing (80) onto the user. The housing (80) includes two switches (81, 82) for testing purposes, and two further switches (83, 84) for input and output information from the signal emitter or for input information into the memory (40) via the CPU (20). A vibration sensor is adapted to generate an output signal indicative of user movement for determining a condition of the user.
