摘要:
Equipment on automotive vehicle is controlled by a system including at least one semiconductor light sensor having variable sensitivity to light. Each light sensor generates a light signal indicative of the intensity of light incident on the light sensor. Control logic varies the sensitivity of the light sensor and generates equipment control signals based on received light signals. Sensitivity of light sensors may be varied by changing the integration time for producing charge from light incident on light transducers, by selecting between light transducers of different sensitivity within the light sensor, by using a light transducer with a sensitivity that is a function of the amount of incident light, and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors, headlamps, and moisture removal means.
摘要:
Equipment on automotive vehicle (20) is controlled by a system at least one semiconductor light sensor (170, 170′) having variable sensitivity to light. Each light sensor generates a light signal (164) indicative of the intensity of light incident on the light sensor. Control logic (66) varies the sensitivity of the light sensor and generates equipment control signals (166) based on received light signals. Sensitivity of light sensors (170, 170′) may be varied by changing the integration time (228) for producing charge from light (176) incident on light transducers (178), by selecting between light transducers (178, 490, 500, 504) of different sensitivity within the light sensor (170), by using a light transducer (530) with a sensitivity that is a function of the amount of incident light (176), and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors (24,26), headlamps (44), and moisture removal means (38, 40, 42).

A vehicle communication and control system is provided that may be more readily installed in a vehicle and that utilizes minimal additional wiring. According to some of the disclosed embodiments, the electrical components of the “brick” of a communication and control system are integrated into a rearview mirror assembly. Preferably, the microwave antenna for the GPS and the cellular telephone antenna are also integrated into the rearview mirror assembly. Various functions and features of the system are also disclosed.
摘要:
A microphone includes one or more transducers positioned in a housing. Circuitry is coupled to the transducer for outputting an electrical signal such that the microphone has a main lobe directed forwardly and attenuates signals originating from the sides. The microphone transducers can advantageously include multiple transducers, which with the circuit produce a desired sensitivity pattern. The microphone can be employed in a vehicle accessory.

摘要:
A vehicle antenna system incorporated into at least one side-view mirror of a vehicle includes a forward directed antenna and a rearward directed antenna to transmit and receive signals over corresponding forward and rearward-directed detection fields, respectively. The antennas act as directional transmitters and/or receivers, and a processing circuit discriminates between signals from different antennas without requiring any of the antennas to transmit identification signals to the processing circuit. Signal discrimination is conducted in part by sequentially selecting each antenna to obtain a corresponding antenna signal and, if required for a particular application, comparing the obtained signal with previously obtained antenna signals. The vehicle antenna system can be used, for example, in conjunction with tire pressure sensors to detect low tire pressure in a particular tire.
