    摘要： A proximity sensor measures receptor output with an energy source deactivated. The sensor then measures receptor output with the energy source activated. The measurements with the energy source activated are compared to the measurements with the energy source deactivated to compensate for the effect of ambient conditions. A near condition is recognized if the change between the two groups of measurements exceeds a designated value. To compensate for receptor output that may decrease after reaching a peak value during approach of an object, a near condition can be maintained until the change between the two groups of measurements no longer exceeds a different designated value. Multiple sensors can be used to avoid false near conditions caused by, e.g., placing a device equipped with the sensors next to a stationary object. In one embodiment, a sensor comprises an infrared light emitting diode and a phototransistor.

    摘要： A computer input device controller dynamically adjusts the rate at which an illumination source is activated, and may also adjust the rate at which other optical tracking system components are activated. As the velocity of optical tracking system movement relative to a tracked surface increases, the controller increases the activation rate(s). As the velocity of relative movement decreases, the controller decreases the activation rate(s). Future displacements of a tracking system relative to a tracked surface are also estimated. In particular, relative tracking system/tracked surface velocity is calculated based on a series of images. Relative displacement is then estimated based on the calculated velocity.

    摘要翻译： 计算机输入设备控制器动态地调节照明源被激活的速率，并且还可以调整激活其他光学跟踪系统组件的速率。 随着光学跟踪系统相对于跟踪表面移动的速度增加，控制器增加激活速率。 随着相对运动速度的降低，控制器降低了激活速率。 还估计跟踪系统相对于被跟踪表面的未来位移。 特别地，基于一系列图像来计算相对跟踪系统/跟踪表面速度。 然后基于计算的速度来估计相对位移。

    摘要： A surface acoustic wave (SAW) sensor includes a transducer (240 provided on a substrate (23), wherein the transducer (24) is oriented on the substrate (23) so that the direction of acoustic wave propagation is such that the variation of sensor output with temperature, associated with the variation of the substrate third-elastic constants with temperature, substantially equal but opposite to the sum total of the variation of sensor output with temperature associated with the substrate linear temperature coefficient of expansion and with the variations with temperature of the substrate non-zero third order elastic constants, the substrate first-order elastic constants and the substrate density. The effect of temperature variation on sensor output is thereby minimized. This is achieved with a 35-degree arrangement or with reflective gratings inclined at an angle of 3.1 degrees to normal. Additionally, a robust package with a dish is given. Particular applications include the measurement of torque.

    摘要： A pressure monitor has a base and a lid secured to the base to define a substantially fluid tight chamber. At least part of the lid is flexible and forms a diaphragm which deflects responsive to changes in fluid pressure surrounding the monitor. A projection provided on the diaphragm transmits movement thereof to a distortable substrate located within the chamber. A first SAW device is mounted on the distortable substrate, and at least a second and third SAW device are mounted within the chamber. The second SAW device carried on a reference substrate section has its direction of propagation inclined at an angle to the direction of propagation of at least one of the first and third SAW devices. This way movement of the diaphragm induced by a change in pressure in the zone surrounding the monitor results in distortion of the distortable substrate, which is measurable by the SAW device mounted thereon, without distorting said reference substrate section.
