20140285220 | PARASITIC CAPACITANCE CANCELLATION IN CAPACITIVE MEASUREMENT - An integrated circuit compensates for parasitic capacitance in a capacitive measuring apparatus wherein a capacitance measurement is done by repeatedly transferring charge from a capacitor to be measured to a reference capacitor. | 09-25-2014 |
20140253032 | CAPACITIVE SENSING ENABLED SWITCH MODE POWER SUPPLY AND DATA TRANSFER - A microchip for control of a switch mode power supply (SMPS), with said microchip also having the ability to measure capacitance of an electrode or sense plate structure or structures, and use of a low power, power supply structure to supply said microchip, said power supply structure distinct from the main energy path via said SMPS to a load. The microchip may control said SMPS to transition between an active state and an inactive state, with the measured capacitance used to determine a condition for state transition. In said SMPS inactive state, only the microchip draws power to operate its capacitive sensing circuitry, leading to a significant SMPS standby losses decrease compared to prior art. Further teachings by the present invention include capacitive sensing based data transfer, universal charging platforms for mobile devices, noise immunity enhancements, various lighting embodiments as well as SMPS operation improvements. | 09-11-2014 |
20130033190 | Intelligent User Interface Including A Touch Sensor Device - The present invention, according to a preferred embodiment, is directed to portable electronic devices which operate on exhaustible power sources, for example, batteries. The electronic devices of the present invention comprise at least one signal switch and a microchip in communication with the switch wherein the switch is only capable of transmitting a signal to the microchip that the switch has been activated or deactivated. The microchip is in communication with the exhaustible power source of the electronic device and controls (i) the power on/off function of the device, (ii) at least one other function of the device in response to activation and deactivation signals from the switch, and (iii) an automatic shut off function in response to the receipt of an activation signal from the switch. | 02-07-2013 |
