| 41 | CONTROL AND TESTING OF A MICRO ELECTROMECHANICAL SWITCH HAVING A PIEZO ELEMENT | US11465319 | 2006-08-17 | US20080042518A1 | 2008-02-21 | Lianjun Liu |
| A micro electromechanical switch has a movable portion positioned to form an electrical connection between a first electrical contact and a second electrical contact. A piezoelectric electrode is formed on the movable portion. The piezoelectric electrode causes the movable portion to move in response to a driver voltage. A piezo element is formed on the movable portion of the switch. The piezo element is for detecting movement of the movable portion between an open position and a closed position. The piezo element is also used to detect switch bouncing when the switch transitions from the open position to the closed position. In one embodiment, the piezo element is a piezoelectric element and in another embodiment the piezo element is a piezo-resistive element. | ||||||
| 42 | Electric switch, especially a piezo switch, with optical and/or mechanical feedback of the switching operation | US10415967 | 2001-11-02 | US07250708B2 | 2007-07-31 | Mathias Stadelmann |
| The invention relates to an electric switch, especially a piezo switch, with optical and/or mechanical feedback of the switching operation. The switch contains at least one switching element, especially beneath a cover panel, which can be activated by means of an activating element. This causes a switching signal to be generated and guided out via electrical contacts. The activating element itself is configured in the form of a passive luminous body consisting of an at least translucent material, which can be illuminated by active luminous means. The mechanical feedback of the switching operation can take place using a vibrator which is activated by the switching operation that has been initiated and conveys a vibrating motion to the luminous body. | ||||||

| The present invention relates to a method for the production of a combined piezo/luminescent film for use as actuating element, especially in vehicles, comprising the steps: provision of a film-type base material (1); application of a piezoelectric varnish (2) onto the base material at least in a first partial area (A1, A2) so as to form a piezoelectric switch surface in the first partial area; application of a luminescent varnish (3) onto the base material in at least a second partial area (B1, B2) so as to be able to illuminate the switch surface in the second partial area; covering at least of the first and second partial area with a top layer (4) that is bonded to the base material. In addition, the present invention describes an actuating element with a combined piezo/luminescent film produced in such a manner. | ||||||

| 46 | Input device for game controller | US09796459 | 2001-03-02 | US06552288B2 | 2003-04-22 | Atsushi Ono |
| A first electrode and a second electrode are disposed on a base board. A resist is formed on the base board so as to cover the first electrode. A capacitance-operated silicon rubber sensor is provided on the base board so as to cover the resist and the second electrode. A click rubber is disposed above the silicon rubber sensor. A button deforms the click rubber so as to press down the silicon rubber sensor and the resist. The silicon rubber sensor and the resist generates an analog output signal between the first and second electrodes in proportion to a force pressing the button, when the pressing force is larger than a predetermined pressing force enough to deform the click rubber so as to establish the output signal. | ||||||

| 51 | Weatherproof electronic keypad with replaceable graphics overlay | US363296 | 1994-12-23 | US5674018A | 1997-10-07 | Peter Kaufman; John C. Echols; Henry Miszkiewicz |
| A weatherproof electronic keypad includes a molded plastic housing, a plurality of transducers attached to the inside surface of the front wall of the housing, an electronic circuit mounted within the housing and connected to the transducers, and a graphics overlay removably affixed to the outside surface of the front wall of the housing. The front wall and overlay are sufficiently flexible that finger pressure applied to the overlay results in enough deformation of the front wall to activate the transducer underlying that portion of the inside surface. The overlay contains indicia which identify the location and function of the transducers. The overlay need not be attached to the housing as a part of manufacturing the keypad, but rather can be added in situ as part of installation of the keypad. This enables customized selection of a particular overlay in accordance with aesthetic and/or functional considerations, as well as replacement of the overlay in the field if necessary. | ||||||

| 54 | Controller-Less Quick Tactile Feedback Keyboard | US15365942 | 2016-11-30 | US20170084408A1 | 2017-03-23 | Masaaki Fukumoto |
| In some examples, techniques are provided for quick haptic feedback, without the use of a controller, which is local to individual, non-actuating keys, such as keys of a thin keyboard or keypad. The haptic feedback may be in the form of a simulated “key-click” feedback for an individual key that is pressed by a user such that the finger used to press the key feels the tactile sensation. The haptic feedback mimics the tactile sensation of a mechanical key (e.g., buckling spring, pop-dome key switch) to give a user the perception that they have actuated a mechanically movable key. | ||||||
