Abstract
1469508 Radio signalling; serials S G A SWALES 5 March 1974 [16 May 1973] 23344/73 Headings H4L and H4A In an alarm system, e.g. for use by the elderly to signal an emergency, or in a security system, a radio transmitter is incorporated in a wristlet and has an aerial connection positioned to be electrically coupled with the wrist of the user so that the body is used as an aerial. The wristlet contains a switch whereby the wearer may operate the transmitter in an emergency, so that an alarm is given at a receiver forming part of the system. The transmitter casing may contain a timepiece which may be electrically operated using the same power source as the transmitter. The transmitter may emit an audio or visual signal in addition to the radio transmission.
