Abstract: An electronic vehicular signalling system is disclosed. It has a novel turn signal switch having electromagnetic detents, novel electronic circuitry which provides all standard signalling functions and optionally features automatic cancellation of turn signal switch, an energy saving hazard warning mode, a police alert hazard warning mode, double-rate turn signal flashing on lamp burnout, Vehicular Lamp Status Display System, clicking sound in cadence with flashing or tone, and automatic turn signal timeout with choice of timeout intervals. Separate flasher units are not needed, nor a microprocessor.

Abstract: A lamp-diagnosing system comprising electronic current-indicating apparatus and a dashboard display scheme, for vehicles: The system provides a dashboard display which shows the actions of external signaling lamps and hence their status (monitoring mode). Another embodiment provides indication only when a lamp fails (alarm mode). The invention offers improved operator awareness of vehicular signaling, serviceability, improved safety, low cost, and ease of incorporation into existing circuitry.

Abstract: An electronic flasher switch, for use in vehicular signalling systems. The flasher features automatic timeout and an audio oscillator for timing and for optional audio signalling to supplement interior turn signal dash indicator lights. A single integrated circuit and two small capacitors allow compact, low cost implementation.

Abstract: An opto-electronic device for accurately defining the position of a pendulum in libration, is disclosed. The chief use intended by the inventor is to enable accurate passive determination of the beat rate of a newly installed or repaired pendulum type clock. The device is easy to use and does not perturb the pendulum. A novel circuit configuration automatically recognizes an edge of a pendulum for production of a defining electronic pulse.

Abstract: A direct current power supply configuration for use in a wide variety of electronics applications, is described. The invention features high precision capability with relatively simple circuitry. A system of panel indicators eliminates the need for a panel voltmeter and improves serviceability and ease of operation over the prior art.

Abstract: An improved device for detecting ticking sounds produced from inside some mechanism, is described. The purpose of the device is to sense the ticks and produce a well defined electrical pulse for each tick while rejecting other noises and electrical interference. Previous devices for this purpose have typically employ-commercially available microphones as the sensor. The invention employs a combination of sensor and circuitry which gives improved rejection of noise, and a signal to noise ratio in excess of 10:1 under most conditions.
