20110073384 | CAPACITIVE TOUCH SENSOR DEVICE CONFIGURATION SYSTEMS AND METHODS - Embodiments include capacitive touch sensors and methods for configuring capacitive touch sensors. A capacitive touch sensor embodiment includes an analog-to-digital converter (ADC) and a controller. The ADC receives an analog voltage signal from an electrode, and samples the analog voltage signal to produce a plurality of digital values. The controller performs a first charging process by supplying the electrode with a first charging current for a first charging interval, and the controller determines, based on the digital values, whether a first electrode voltage value meets a criteria. If not, the controller performs a configuration process that results in setting a second charging current and a second charging interval for the electrode which, in response to performing a second charging process, results in a second electrode voltage value that meets the criteria. | 03-31-2011 |
20110120784 | Methods and apparatus for performing capacitive touch sensing and proximity detection - Embodiments include methods and apparatus for performing capacitive touch sensing and proximity detection. Electrode selection circuitry establishes a first connection with an individual electrode of a plurality of individual electrodes in order to receive one or more first signals indicating a state of the individual electrode, and establishes second connections with a proximity electrode that comprises multiple ones of the plurality of individual electrodes in order to receive one or more second signals indicating a state of the proximity electrode. A processing system performs a first analysis on the first signals to determine whether to perform a first updating process for an individual electrode baseline value, and performs a second analysis on the second signals to determine whether to perform a second updating process for a proximity electrode baseline value. In an embodiment, the first analysis and the second analysis are different from each other. | 05-26-2011 |
20110121656 | Systems and methods for delivering power in response to a connection event - Systems and methods are provided for delivering power from a first energy source to a second energy source. An electrical system for delivering power from a first energy source to a second energy source comprises an interface configured to be coupled to the second energy source, a switching element coupled between the first energy source and the interface, and a processing system coupled to the switching element and the interface. The processing system is configured to identify a connection event based on an electrical characteristic of the interface that is indicative of the interface being coupled to the second energy source and operate the switching element to provide a path for current from the first energy source in response to identifying the connection event. | 05-26-2011 |
20110232976 | CAPACITIVE TOUCH PAD WITH ADJACENT TOUCH PAD ELECTRIC FIELD SUPPRESSION - A capacitive touch pad includes an electrode board, a plurality of capacitive touch sensor pads, and a cover. The electrode board has touch sensor circuitry formed thereon. The plurality of capacitive touch sensor pads is formed in an array over the touch pad circuitry of the printed circuit board. The plurality of capacitive touch sensor pads is spaced apart by a predetermined distance to form spaces between the pads of the plurality of capacitive touch sensor pads. The cover is positioned over and covering substantially all of the plurality of capacitive touch sensor pads. The cover has a first cavity with a first depth, where the first cavity is shaped to form an air gap between the pads of the plurality of capacitive touch sensor pads to dampen capacitive coupling between adjacent touch pads. | 09-29-2011 |
20150124148 | DEVICES HAVING AUTOMATICALLY ADJUSTABLE POLARIZERS AND RELATED OPERATING METHODS - Devices having adjustable polarizers and related operating methods are provided. An exemplary electronic device includes one or more sensing arrangements, a polarization arrangement including a polarizer, and a control module coupled to the one or more sensing arrangements and the polarization arrangement. The control module determines an angle for the polarizer based at least in part on output from the one or more sensing arrangements and operates the polarization arrangement to achieve the angle. In one or more exemplary embodiments, the angle corresponds to an orientation of the polarizer in a plane substantially orthogonal to a line-of-sight that is configured to result in the polarizer absorbing incident light rays emanating from the sun that are aligned with the line-of-sight. | 05-07-2015 |
