摘要： A heads-up display system is configured for use in a vehicle. The system includes a standard vehicle window (i.e. no special coatings), an image projector, and a vehicle dashboard equipped with a faceted reflective surface. The image projector is configured to project an image onto the faceted reflective surface. The faceted reflective surface is configured to reflect the image from the image projector onto a window surface of the standard vehicle window. The window surface is oriented to reflect the image from the faceted reflective surface toward an occupant. The faceted reflective surface may be disposed within a plurality of troughs separated by a plurality of diffuse reflecting partitions. The plurality of troughs may be configured to shield the occupant from extraneous reflections. The faceted reflective surface may include a plurality of electrically controlled facets. The plurality of electrically controlled reflective facets may be an array of electrowetting cells.

摘要： Driver distraction in a motor vehicle is assessed by capacitively detecting the driver's head pose relative to the forward direction of vehicle motion. A symmetrical array of sensor electrodes is disposed in the cockpit ceiling above the driver's head, and pairs of electrodes disposed along varying axes of rotation with respect to the forward direction are successively activated for capacitance measurement. The capacitance measurements are combined to form a signal whose strength depends on the degree of alignment between the driver's head (i.e., the head pose) and the respective axes of rotation, and the driver's head pose is calculated to assess driver distraction.

摘要： An integrated sensor comprising a thermopile transducer and signal processing circuitry that are combined on a single semiconductor substrate, such that the transducer output signal is sampled in close vicinity by the processing circuitry. The sensor comprises a frame formed of a semiconductor material that is not heavily doped, and with which a diaphragm is supported. The diaphragm has a first surface for receiving thermal (e.g., infrared) radiation, and comprises multiple layers that include a sensing layer containing at least a pair of interlaced thermopiles. Each thermopile comprises a sequence of thermocouples, each thermocouple comprising dissimilar electrically-resistive materials that define hot junctions located on the diaphragm and cold junctions located on the frame. The signal processing circuitry is located on the frame and electrically interconnected with the thermopiles. The thermopiles are interlaced so that the output of one of the thermopiles increases with increasing temperature difference between the hot and cold junctions thereof, while the output of the second thermopile decreases with increasing temperature difference between its hot and cold junctions.

摘要： An airflow sensor formed on a silicon chip comprises a silicon base covered with an insulating polyimide layer, a lineal resistance heater on the chip energized with current pulses to propagate thermal waves, and a thermistor on the chip downstream of the heater to detect the arrival of each thermal wave. Circuitry determines flow rate as a function of the measured propagation time of the thermal wave. The thermistor may be replaced by a bridge of four resistive elements of which only one or two are sensitive to the thermal wave. The thermistor material is platinum, polycrystalline silicon or amorphous silicon which exhibit high temperature coefficients of resistance.
