Patent number: 9927927Abstract: In one embodiment, a method includes applying a drive signal to an electrode of a touch sensor of a device. The touch sensor extends across an area of a surface of the device, and the drive signal is configured to generate an electric field that extends outward from the area of the surface that the touch sensor extends across and reaches a pre-determined location on the device that is outside the area of the surface that the touch sensor extends across. The method includes receiving a sense signal from the touch sensor produced at least in part by the electric field. The sense signal indicates whether an object has come within a pre-determined proximity of the pre-determined location.Type: GrantFiled: May 5, 2014Date of Patent: March 27, 2018Assignee: Atmel CorporationInventors: Trond Pedersen, Steinar Myren, Vemund Bakken, Rune Watn

Patent number: 8421666Abstract: In one embodiment, an apparatus includes a first capacitor system and a second capacitor system. Each capacitor system comprises one or more engaged capacitors from respective pluralities of selectively engagable capacitors. The first capacitor system and second capacitor system are respectively selectively coupled to a first reference voltage and a second reference voltage. The apparatus further includes a switch configured to transfer charge between the first capacitor system and the second capacitor system when the switch is closed such that the first capacitor system and the second capacitor system each store the same first voltage. The apparatus further includes a node coupled to the first capacitor system, the second capacitor system, and a first input of a differential amplifier of an analog to digital converter. The node is configured to bias the differential amplifier to the first voltage.Type: GrantFiled: August 11, 2011Date of Patent: April 16, 2013Assignee: Atmel CorporationInventor: Trond Pedersen

Patent number: 8416117Abstract: In one embodiment, an apparatus comprises a first capacitor system and a second capacitor system. Each capacitor system is removably coupled to the same portion of an analog to digital converter (ADC) and the same sensing circuit. Each capacitor system stores charge received through the sensing circuit when coupled to the sensing circuit and provides the charge received through the sensing circuit to the ADC for conversion into a digital value when coupled to the ADC. When the control signals are in a first state, the first capacitor system receives charge through the sensing circuit and the second capacitor system is coupled to the portion of the ADC. When the one or more control signals are in a second state, the second capacitor system is coupled to the sensing circuit to receive charge through the sensing circuit and the first capacitor system is coupled to the portion of the ADC.Type: GrantFiled: August 11, 2011Date of Patent: April 9, 2013Assignee: Atmel CorporationInventor: Trond Pedersen
