摘要： A system selectively completes a horn circuit through which electrical power is provided to a horn in an automobile. A relay is connected to a power supply and completes the horn circuit when a current signal passing through the relay has at least a threshold magnitude. A relay driver is selectively activated by processing circuitry. When it is activated, the relay driver is in a conductive state, and when it is not activated, the relay driver is in a high impendance state. When the relay driver is in the conductive state, it places the relay in series with a low potential conductor thereby establishing the current signal at at least the threshold magnitude. The processing circuitry is electrically connected to a manually actuated sensor, which may be a flexible potentiometer. The processing circuitry activates the relay driver when the manually actuated sensor is actuated. The processing circuitry receives electrical power from the relay when the relay driver is in the high impendance state, but receives essentially no electrical power from the relay when the relay driver is in the conductive state. While the processing circuitry receives essentially no electrical power from the relay, the processing circuitry momentarily places the relay driver in the high impendance state so that the processing circuitry may receive electrical power from the relay and determine whether the manually actuated sensor is still actuated. An auxiliary power supply provides electrical power to the processing circuitry while electrical power is not received from the relay.
摘要翻译： 一种系统选择性地完成一个喇叭电路，通过该喇叭电路向汽车中的喇叭提供电力。 当通过继电器的电流信号至少具有阈值幅度时，继电器连接到电源并完成喇叭电路。 继电器驱动器由处理电路选择性地激活。 继电器驱动器激活时，处于导通状态，当未激活时，继电器驱动器处于高阻塞状态。 当继电器驱动器处于导通状态时，它将继电器与低电位导体串联，从而以至少阈值大小建立电流信号。 处理电路电连接到手动致动的传感器，传感器可以是柔性电位计。 当手动致动的传感器被致动时，处理电路激活继电器驱动器。 当继电器驱动器处于高阻塞状态时，处理电路从继电器接收电力，但当继电器驱动器处于导通状态时，基本上不从继电器接收电力。 虽然处理电路基本上不从继电器接收电力，但是处理电路将瞬时地将继电器驱动器置于高阻止状态，使得处理电路可以从继电器接收电力并且确定手动致动的传感器是否仍然被致动。 辅助电源向处理电路提供电力，而不从继电器接收电力。

摘要： A multi-function control system to control a variety of operations associated with a powered surgical device such as an arthroscopic surgical shaver. The system has an ergonomically designed foot switch which has a plurality of discrete force sensitive transducers arranged in an arcuate pattern. The transducers have no moving parts and have a force sensitive element which produces a variable output which is a function of the force applied by a user. The foot switch is used in conjunction with a control console which enables a user to adjust the force sensitivity threshold of the transducers. The foot switch additionally has physically discrete and tactilely sensible areas enabling a user to activate selected functions with a minimal amount of foot movement.

摘要： A foot switch includes a base member having an upwardly facing surface, a force sensing resistor disposed on the surface and coupled electrically to a sensing circuit, and an actuating layer disposed on the force sensing resistor and the base member surface. The actuating layer has an elevated portion which is substantially centered over the force sensing resistor, the elevated portion having a convex upper surface which is a portion of a spherical surface. The sensing circuit includes a constant current source connected in series with the force sensing resistor between ground and a predetermined voltage.

摘要： A trimmable resistor which is prepared with additional electrical contacts between the resistor and the substrate. These contacts are usually not connected electrically to the electronic circuit. Moreover, they do not extend across the entire width of the resistor. If the resistor is over trimmed, its resistance can be reduced by wire bonding a selected one of the additional electrical contacts to an end contact of the resistor. Multiple contacts may be placed along the substrate, both on the side of the resistor where trimming is to take place and on an opposite side.

摘要： A method of making a foil-type electrical resistance strain gage having a gage factor of at least 4. A PtW foil is adhesively bonded to a polyimide substrate with an FEP adhesive cured under heat and pressure. The foil is spin-coated with a positive photoresist, masked, and exposed to ultraviolet light. The exposed photoresist is then developed, permitting wet etching of the foil to form a gage pattern on the substrate, which is then preferably cured.
