Abstract:
A dimming control circuit for use in an illuminated vanity mirror includes a surface formed variable resistor on a circuit board and wiper contacts engaging the resistor. One of the resistor or wiper contacts is movably mounted to a mirror frame with the other of the resistor or wiper contacts being stationary such that the resistance can be varied to control the light intensity.
Abstract:
A visor system includes a pair of spaced mounting brackets to support a first visor movable between a raised stored position and a lowered use position and one which can be moved to a side window for providing protection against incident light from the side. The brackets also support an auxiliary visor which is pivoted on an axis located above the vehicle's windshield between a raised, stored position and a lowered, use position and is movable laterally along the axis.
Abstract:
A tire pressure monitoring system identifies tire locations by recognizing that certain characteristics are unique to front-located tires verses rear-located tires as well as left-side tires and right-side tires. A control circuit is coupled to a temperature sensor and an accelerometer for each tire to receive information processed to discriminate between left and right and front and rear tires, respectively. With this information and a pressure signal, the monitoring system provides the operator with tire location and pressure information without reprogramming upon tire rotation. The system also alerts the operator to run-flat tire operational constraints.
Abstract:
A compass circuit has a magnetic field sensor adapted to be positioned in a vehicle near a source of varying magnetic fields. A detector is coupled to the compass circuit for providing a signal applied to the compass circuit which responds for displaying the compass heading prior to the magnetic field disturbance to provide accurate heading information. In a preferred embodiment, the detector senses when a door is opened and the compass heading prior to the opening of the door is displayed.
Abstract:
A modular electronic system for vehicles employing a microprocessor to facilitate the implementation of additional vehicular features embodied in electronic accessory modules. The system includes a housing with separate mounting areas for receiving at least one of a plurality of plug-in electrical modules and one of a plurality of display boards for displaying information relating to associated modules.
