Abstract
Abstract This invention has for its object to activate buzzers and lamps provided in warning and signalling apparatuses for automotive vehicles by the vibration of a common source such as to simplify the construction as well as to ensure reliable function. This invention resides in electrically stimulating a tiny quartz-oscillator sealed in a capsule to vibrate at an ultra-high frequency, passing the signal from the oscillator through a frequency-divider so as to split it into a number of lesser frequency signals, amplifying them and feeding appropriate signals to buzzers and lamps.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
136 words
An electronic control apparatus for use in combination with an automotive vehicle comprising: a common ultra-high frequency signal source; frequency dividing means having a plurality of output lines and having its input line connected to said source for splitting said ultra-high frequency signal to a plurality of differing lesser frequency signals so that a differing frequency signal is present on each of said output lines; signal processing means connected to each of said output lines of said frequency dividing means for individually amplifying and shaping each differing lesser frequency signal; a plurality of electronically actuated signalling devices, each device having an input connected to the output line of one of said signal processing means so that the output from said signal processing means powers said signalling device, and means for selectively actuating said signal processing means.
Claim 2
Dependent Claim
136 words
An electronic control apparatus for use in combination with an automotive vehicle comprising: a common ultra-high frequency signal source; frequency dividing means having a plurality of output lines and having its input line connected to said source for splitting said ultra-high frequency signal to a plurality of differing lesser frequency signals so that a differing frequency signal is present on each of said output lines; signal processing means connected to each of said output lines of said frequency dividing means for individually amplifying and shaping each differing lesser frequency signal; a plurality of electronically actuated signalling devices, each device having an input connected to the output line of one of said signal processing means so that the output from said signal processing means powers said signalling device, and means for selectively actuating said signal processing means.
Claim 3
Dependent Claim
17 words
