摘要： A piezoelectric active-mode incrementor switch system (100) includes two ratchet wheels (118, 124) that are rotationally mounted on a drive shaft (112) having a knob (102). The ratchet wheels (118, 128) form a slipping clutch with their respective drive wheels (116, 128) which are rigidly mounted to the drive shaft and mechanically loaded with spring (120). The ratchet wheels (118, 124) are mounted inversely to each other on the drive shaft (112) and make contact with their respective cantilever beams (114, 136) which each have a piezoelectric film. In operation, the switch (100) functions by mechanically stimulating the piezoelectric beams. When the knob (102) is rotated in one direction, only one of the beams (114, 136) is displaced causing a generation of an electrical charge that acts as a signal. The other beam (114 or 136) is prevented from moving and therefore its beam does not produce a signal. When the knob (102) is rotated in the opposite direction, the other beam that was previously prevented from moving is displaced causing an electrical signal to be generated by the switch.
摘要翻译： 压电有源模式增量开关系统（100）包括两个棘轮（118,124），其旋转地安装在具有旋钮（102）的驱动轴（112）上。 棘轮（118,128）与其相应的驱动轮（116,128）形成滑动离合器，其刚性地安装到驱动轴并机械地装载弹簧（120）。 棘轮（118,124）在驱动轴（112）上彼此相反地安装，并与其各自具有压电膜的各自的悬臂梁（114,136）接触。 在操作中，开关（100）通过机械地激励压电波束来起作用。 当旋钮（102）沿一个方向旋转时，只有一个光束（114,136）被移位，导致产生充当信号的电荷。 防止另一个光束（114或136）移动，因此其光束不产生信号。 当旋钮（102）沿相反方向旋转时，先前防止移动的另一个光束发生位移，导致开关产生电信号。

摘要： A piezoelectric switch (10) is made by laminating one piezoelectric film (16) on the top and a second piezoelectric film (18) on the bottom sides of a stiff central core (14). The central core has one or more actuation areas or poppels (12) formed therein. Each piezoelectric film has an electrically conductive portion (15, 17) formed directly over the actuating area. When the actuating area on the laminate is depressed (11), the piezoelectric films each generate an electric signal that is sent through the electrically conductive portions, thus creating a switching signal.

摘要： A frequency domain switch (100) utilizes an array of cantilevered beams (108) laminated with a piezoelectric material (126). Each of the beams has a unique geometry, and produces a sinusoidal electrical signal in the piezoelectric film that is assignable only to one of the cantilevered beams. When a free end of one of the cantilevered beams is deflected, it produces a signal that is analyzed by suitable circuitry (410-440) to read the position of the switch.

摘要： A method for ultrasonically welding two plastic parts together. One part (30) has a weld joint feature (23) that is covered with a metal layer (27), and the other plastic part (25) has a complimentary weld joint feature. The two parts are joined together by ultrasonically welding the two weld joint features to each other. A force (40) is applied to the first and second plastic parts prior to the step of welding. The force is substantially in excess of that required to cause the two weld joint features to contact each other. This method creates an ultrasonic welded metallized plastic assembly. Each part of the assembly has a weld joint feature, at least one of which was covered with a metal layer prior to welding. Portions of the each of the two weld joint features are deformed to form a plastic weld joint through the metal coating.

摘要： A method of fabricating an elastomeric keypad having a hard key cap over the elastomeric key. A sheet (50) containing a key cap (24) with graphics (26) is placed onto a first plate (52) of a molding tool (54). A second plate (58) is then attached to the first plate, covering the graphic film. The first plate and the second plate interact in a manner such that the key cap containing the graphic is excised out of the film and retained in the molding tool assembly. The waste material (60) surrounding the key cap is displaced away from its original position. A third plate (64) is then attached to the assembled first and second plates. The assembled molding tool creates a cavity (66) that is representative of the keypad assembly, and an elastomeric material is molded into that cavity. Afar the elastomeric material (12) solidifies, the tool is opened, the molded keypad assembly (10) containing the integrally attached rigid key caps is removed.
