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： A chemical vapor sensor is provided that passively measures a chemical species of interest with high sensitivity and chemical specificity. In an aspect, ethanol vapor in a vehicle cabin is measured, and sufficient sensitivity is provided to passively detect a motor vehicle driver that exceeds a legal limit of blood alcohol concentration (BAC), for use with vehicle safety systems. The sensor can be situated in an inconspicuous vehicle cabin location and operate independently without requiring active involvement by a driver. A vapor concentrator is utilized to amplify a sampled vapor concentration to a detectible level for use with an infrared (IR) detector. In an aspect, in comparison to conventional chemical sensors, the sensitivity of detection of ethanol vapor is increased by a factor of about 1,000. Further, a single channel of infrared detection is utilized avoiding spurious infrared absorption and making the chemical vapor sensor less costly to implement.

摘要： A transparent overlay input device includes a transparent non-conductive substrate, a plurality of transparent conductive electrode pairs and a transparent non-conductive cover. The plurality of transparent conductive electrode pairs are formed on the substrate and each form a proximity sensitive region and include a first electrode that receives an input signal and a second electrode that provides an output signal. The first and second electrodes are capacitively coupled and the capacitance of the electrode pair changes when a conductive member, e.g., a user's finger, is located near the electrode pair. The transparent non-conductive cover is formed on the substrate over the electrode pairs.
