Abstract: A printed circuit board (PCB) has a plurality of switch interfaces on its top surface. Each interface is an array of sensors, such as proximity sensors, hall-effect sensors, or a series of inductor coils. The sensors in each array are closely mounted and are all the same for a given PCB. Each array may or may not mount a non-contacting switch selected from a plurality of different types of switches, such as a single push button switch, dual push button switch, a toggle switch, a 3-position rocker switch, a rotary switch, or other type switch. Each switch mounted on the PCB includes one or more indicators for sensing by the sensors or coils, with feedback to determine what type of switch is mounted in each position. The same PCB, or other mount, may thus be used for a variety of unique applications, such as switch packs used in vehicles.

Abstract: An angular position sensor employs a pair of magnets that are disposed on a rotating cylinder at opposite ends of a diameter of the cylinder. A hall-effect flux sensor is fixed within the cylinder and offset from a line of geometric symmetry between the magnets. The offset sensor detects a linear change in flux of the magnets as the magnets rotate with the cylinder over a predetermined angular distance and thereby determines the angular position of the cylinder. The offset of the sensor is adjusted to reduce the sensing error.

Abstract: An automotive seat includes optical sensors for determining a load on the seat, such as a person. The sensors may be used with a computer and computer software to analyze data from the sensors in determining a weight of the load, and the sensors may also be used to determine a shape of the load. From the weight and shape of the load, the computer may decide whether the load is suitable for safe deployment of an automatic restraining device, such as an airbag.

Abstract: A method and system for chemical vapor deposition in which preferentially depositing chemical species are formed by extending the residence time of reactant gases in the reaction region. These preferentially depositing species deposit more rapidly on the sides and bottoms of trenches on semiconductor wafers and/or other CVD substrates and thus promote the generation of more uniform films that eliminate expensive post-processing steps such as reverse active masking.
