Patent number: 9543948Abstract: A physical force capacitive touch sensor comprises a capacitive sensor element on a substrate, a physically deformable electrically insulating spacer over the capacitive sensor element and a conductive deformable plane over the physically deformable electrically insulating spacer. A protective deformable fascia may be placed over the conductive deformable plane to provide an environmental seal for physical and weather protection, but is not essential to operation of the capacitive touch sensor. Back lighting is accomplished through a light transmissive layer(s) in the capacitive touch sensor. When the conductive deformable plane is displaced toward the capacitive touch sensor element, the capacitance value of the capacitive touch sensor element changes and that change may be detected and used as an actuation signal.Type: GrantFiled: January 17, 2013Date of Patent: January 10, 2017Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventors: Keith Curtis, Fanie Duvenhage

Patent number: 9144041Abstract: A combination of capacitive, mutual capacitive, and inductive proximity and touch sensing is used to detect the presence and nature of nearby objects to a wireless device. When the proximity of metal or a user is sensed the output power of a Wi-Fi module in the device is reduced so as to prevent harm to the user and/or the Wi-Fi transmitter amplifier circuits. Inductive sensors located at the four corners of the wireless device are used to detect metal, and capacitive sensors are used to detect a capacitance change or shift due to the presence of a user's hand, body or metal. In addition, the capacitive sensors may be located at the four corners of the device and can measure changes in the mutual capacitance coupling between these capacitive sensors.Type: GrantFiled: December 4, 2012Date of Patent: September 22, 2015Assignee: MICROCHIP TECHNOLOGY INCORPORATEDInventors: Keith Edwin Curtis, Yann LeFaou, Fanie Duvenhage

Patent number: 6772090Abstract: An improved vehicle odometer is provided with an encoder and a microcontroller. The encoder has a unique key that configures an encryption algorithm. The encryption algorithm can be in the form of circuitry or software or any combination there between. The encoder receives a increment signal from the vehicle indicating that the vehicle has traveled a pre-determined distance. The encoder then increments the odometer-related value and then encrypts it with the encryption algorithm. The encoder then wraps the encrypted odometer-related value into a data packet with a serial number. Only a suitably equipped computing device, such as a microcontroller, identify and correctly decrypt and process the encrypted odometer-related value, thereby preventing the tampering of the vehicle's odometer.Type: GrantFiled: January 25, 2001Date of Patent: August 3, 2004Assignee: Microchip Technology IncorporatedInventors: Brendon Hutton, Fanie Duvenhage
