Vehicular speed limit reminder with radio control facility - provides eithervisual or audible warning of violation of limit set by driver or roadsidetransmitter

摘要

A basic manual model of the appts. has a keyboard or similar input device whereby the driver can enter a chosen or legally prescribed max. speed. When this is exceeded, a warning lamp is lit or an audible tone (pipe or continuous note) is sounded. A radio-controlled model incorporates a receiver for encoded transmissions from speed restriction signs at the roadside. A third model combines this receiver with the manual input facility. ADVANTAGE - All three models can be combined with equipment for automatic restriction of speed to preset limit.
