Abstract
The location device is for a moving person, such as a skier or a mountaineer. It operates by the emission of radiowaves which are amplitude or frequency modulated as a function of position or orientation. The modulation may also signal presence or absence of movement. A transmitter is incorporated on a rectangular card (1) with an elastic band (2) to fix it by two slots (3, 4) to the arm of a user. A miniature transmitter (5) on the card is powered from a battery (6) via printed conductors (20). This is switched on by a normally open switch (9) which is closed by tightening of the band around the arm. The antenna output (5a) is connected via the switch (9) and a printed conductor (10) to a conducting layer (11) on the card and which contacts metallic elements (7) in the arm band.
