Patent number: 10969857Abstract: In one embodiment, a touch sensor controller includes a processor and a monitoring component coupled to the processor. The monitoring component is configured to perform operations comprising receiving, from an impact sensor, an output signal. The output signal is indicative of a plurality of impacts detected by the impact sensor to a surface of a housing of a device. The monitoring component is further configured to perform operations comprising initiating, based on the output signal corresponding to a predefined impact pattern, a transition of the touch sensor from a first power mode to a second power mode.Type: GrantFiled: December 26, 2018Date of Patent: April 6, 2021Assignee: Amtel CorporationInventor: Martin J. Simmons

Patent number: 10635248Abstract: Assemblies include a chassis having a first side configured to receive a force-sensitive surface, a support structure including first electrode portions, and resilient mounting elements attached to the chassis and to the support structure. The mounting elements include second electrode portions positioned adjacent to the first electrode portions. Force-sensitive systems include force sensors including portions of a support structure and portions of a mounting element that are adapted to relatively move responsive to one or more applied forces, and a controller configured to identify the one or more applied forces by determining movement between the support structure and the mounting element. Methods include detecting changes in capacitances of respective capacitors formed by first electrode portions on a support structure and second electrode portions defined by mounting elements coupling a chassis to the support structure.Type: GrantFiled: May 22, 2018Date of Patent: April 28, 2020Assignee: Amtel CorporationInventors: Nigel Hinson, Paul Clements

Patent number: 10567853Abstract: Systems and methods for controlling small grids of appliances are described. One sample method includes receiving consumption data from a plurality of electrical appliances that are plugged into outlets at a first location and monitoring power usage at the first location. The method includes evaluating the received consumption data to identify one or more predetermined conditions in one or more of the plurality of electrical appliances and evaluating stored data related to power consumption preferences at the first location. The power consumption preferences define conditions when a consumer associated with the first location has agreed to enable remote control of at least one designated appliance upon an occurrence of one or more predetermined conditions. The method includes determining that the one or more conditions are satisfied and to provide a first secure communication to the first appliance to control the power consumption.Type: GrantFiled: January 26, 2018Date of Patent: February 18, 2020Assignee: Amtel CorporationInventors: Jeff Kotowski, Charles Cai

Patent number: 9864456Abstract: In one embodiment, a controller includes a processor and a memory, the memory storing logic. The logic is configured to perform, when executed by the processor, operations comprising detecting, in response to driving electrodes of a touch sensor with a first drive signal having a first polarity, a presence of a stylus. The presence of the stylus is detected based on a first sense signal, the first sense signal having a second polarity. The operations further comprise detecting, in response to driving the electrodes with a second drive signal having the first polarity, a second sense signal having a third polarity. The third polarity is an inverse of the second polarity. The operations further comprise driving, in response to detecting the second sense signal having the third polarity, the electrodes with a third drive signal having a fourth polarity. The fourth polarity is an inverse of the first polarity.Type: GrantFiled: December 21, 2015Date of Patent: January 9, 2018Assignee: Amtel CorporationInventor: Thomas Bell
