PERSONAL SAFETY SYSTEM

摘要

A personal safety system is disclosed. The personal safety system comprises: a personal safety device and a base unit coupled over a local communications link; transceiver logic operable to transmit a periodic status message and an acknowledgement message generated in response to each received status message between said personal safety device and said base unit over said local communications link; and alert logic operable, in the event that said transceiver logic indicates that a number of either of said status and acknowledgement messages fail to be transmitted between said personal safety device and said base unit, to activate an alarm mechanism on both said personal safety device and said base unit. Accordingly, the member of crew wearing the personal safety device will detect the alarm mechanism activating and be provided with the assurance that a similar alarm mechanism is activating on the base unit.
