PCT No. PCT/SI94/00019 Sec. 371 Date Jul. 30, 1996 Sec. 102(e) Date Jul. 30, 1996 PCT Filed Dec. 2, 1994 PCT Pub. No. WO95/15546 PCT Pub. Date Jun. 8, 1995The base of a security/prevention system is an electronic device which has the capability of joining the performance of two functions, i.e. prevention of road accidents and theft protection of vehicles, using the principle of joint use of frequencies, whereby interference with the device's operation is prevented. The invention allows, on the one hand, such application in road traffic prevention in which an electronic security device installed in a vehicle provides passive or active warning of participants in the traffic as to possible momentary dangers requiring quick reaction of the driver. On the other hand, the invention allows such application in road traffic safety in which an electronic security device protects vehicles against theft; the device comprises three base units, i.e. an electronic security device, which is installed in the vehicle and intended for transmitting messages about theft, a pocket receiver, and a network of receiver devices distributed at all locations of importance to the reception of the transmitted messages. |
