摘要： An existing vehicle seat design is equipped with strain gauges welded to structural seat members to sense occupant seated weight. A microprocessor compensates for preload on the sensors and multiplies each signal by an empirically determined gain, and then combines the gauge outputs. The combined output is low pass filtered to avoid motion induced errors. The measured occupant seated weight is used by decision logic to decide whether to allow passenger airbag deployment.

摘要： A method of improving the life expectancy of surface mount components is electronic assemblies wherein a distance between the printed circuit board and the surface mount component is held to a predetermined distance defined as the stand-off height. The relationship between the stand-off height and the life expectancy of the component is directly proportional. A larger stand-off height translates into a longer life expectancy. The stand-off height is limited only by manufacturing constraints, such as process limitations and cost concerns. The stand-off height is set to a predetermined dimension by way of a spacer positioned between the surface mount component and the printed circuit board.
摘要翻译：提高表面安装部件的预期寿命的方法是电子组件，其中印刷电路板和表面安装部件之间的距离被保持为限定为间隔高度的预定距离。分离高度与组分的预期寿命之间的关系是直接成正比的。更大的间隔高度意味着更长的预期寿命。对立高度仅受制造限制，例如过程限制和成本问题的限制。通过位于表面安装部件和印刷电路板之间的间隔件将间隔高度设定为预定尺寸。

摘要： A heads up display apparatus for a vehicle having a windshield includes an LED display having alphanumeric characters which are at least reflected off of the vehicle windshield toward the driver. The display has power controls and, optionally, a variable brightness control through a manually driver manipulatable control member or automatically through an ambient light sensor output coupled to the display. A vehicle operating parameter output is coupled to the display and converted by the display into illuminated alphanumeric characters. Each element of each LED character includes a reflected element image and at least a partially refracted and reflected ghost element image which have juxtaposed and overlapped element to form a combined single image to the viewer.

摘要： A clearance gauge comprises a thin foil rolled into a tubular coil at one end and having a flat tab extending from the coil, the coil windings being secured by a layer of adhesive. The gauge is attached via the tab to one of a pair of relatively movable parts and is deformed by compression between the parts to assume a dimension equal to the clearance between the parts. The foil has a low yield strength so that the coil substantially retains the dimension for later measurement to thereby afford a measure of the clearance.

摘要： A filter insert for a terminal connector includes a rigid substrate and low-cost interference fit connections between the filter insert circuitry and the connector terminals. In a first embodiment, the insert includes a flexible circuit bonded to the rigid substrate, and the substrate is provided with over-sized openings that the terminals pass through without interference. A second embodiment is like the first, except that the filter circuit traces are formed directly on the rigid substrate, and the substrate material backing the terminal connection sites is removed to form the over-sized openings.
