Patent number: 8476542Abstract: A flat-type input unit capable of outputting information regarding a position where a finger touches as coordinate data is provided in a casing of an input device. A main-switch unit and sub-switch units operated by the flat-type input unit are also provided in the casing.

Publication number: 20130026026Abstract: A shift lever, a shift knob provided on an upper end of the shift lever, an electrode portion provided on a lower end of the shift lever, an operation fulcrum rotatably supporting the shift lever, and a capacitive coupling sensor located in non-contact with the electrode portion are included. By a movement operation of the shift knob, the shift lever rotates and the electrode portion moves while keeping non-contact with a surface of the capacitive coupling sensor. The capacitive coupling sensor detects a position of the electrode portion on the basis of a capacitance change caused with movement of the electrode portion. By so doing, shift position information and trajectory information between each shift position can be obtained.Type: ApplicationFiled: June 21, 2012Publication date: January 31, 2013Applicant: Alps Electric Co., Ltd.Inventor: Akio NISHIJIMA

Patent number: 8354606Abstract: A push switch includes an operating member, a holding member, a detecting electrode including a plate-shaped spring, a conductive coil spring, and a wiring substrate. The operating member includes a top portion. The rear surface of the top portion and the holding member define a storage space. The detecting electrode, received in the storage space, includes a detecting portion in resilient contact with the top portion, a base in resilient contact with the coil spring, and a height adjusting portion coupling the detecting portion to the base. The amount of compression of the detecting electrode is defined depending on the height of the storage space. The detecting portion detects a change in capacitance caused when the operation surface is touched by a human body and a detection signal indicating the change is output to the wiring substrate through the height adjusting portion, the base, and the coil spring.Type: GrantFiled: August 20, 2010Date of Patent: January 15, 2013Assignee: Alps Electric Co., Ltd.Inventors: Tatsuya Yokoyama, Yu Takeda

Publication number: 20130008769Abstract: Apparatuses and method are described to create a reduced stiffness microstructure (RSM). A RSM is made by forming a first buckled membrane along a first buckling direction and forming a second buckled membrane along a second buckling direction. The second buckling direction is opposite to the first buckling direction and the first buckled membrane is in contact with the second buckled membrane over a contact area. Within an operating zone, a stiffness of the reduced stiffness microstructure spring is less than an absolute value of a stiffness of either the first buckled membrane or the second buckled membrane when the contact area translates along either one of the buckling directions. In the operating zone the stiffness can approach or equal zero.Type: ApplicationFiled: July 5, 2011Publication date: January 10, 2013Applicant: Duality Reality Energy, LLCInventor: Jeffrey Paul Baugher
