Abstract: Accumulators that operate to fully or partially remove noise from a signal, including removing noise inserted into the signal by the accumulator itself. In some embodiments, an accumulator may be operated in a sampling phase and a transfer phase each time the accumulator samples an input signal. In some such embodiments, an op-amp of an accumulation circuit of the accumulator may be auto-zeroed during some or all of the sampling phases of an accumulation period. In some embodiments in which the op-amp is auto-zeroed during some or all of the sampling phases, the accumulation circuit may include a holding capacitor that, during an auto-zeroing process, holds a value output by the op-amp during a prior transfer phase. Including such a holding capacitor in an accumulator may reduce a voltage that the op-amp output rises following the auto-zero process, which may reduce a bandwidth and noise of the accumulation circuit.

Abstract: Embodiments reduce the complexity of speaker dependent speech recognition systems and methods by representing the code word (i.e., the word to be recognized) using a single Gaussian Mixture Model (GMM) which is adapted from a Universal Background Model (UBM). Only the parameters of the GMM need to be stored. Further reduction in computation is achieved by only checking the GMM component that is relevant to the keyword template. In this scheme, keyword template is represented by a sequence of the index of best performing component of the GMM of the keyword model. Only one template is saved by combining the registration template using Longest Common Sequence algorithm. The quality of the word model is continuously updated by performing expectation maximization iteration using the test word which is accepted as keyword model.

Abstract: A borderless touchscreen panel includes a first conductive layer having rows of capacitive sensors and receiving traces, and a second conductive layer having columns of sensor bars and transmitting traces. The capacitive sensors are coupled to control circuitry via the receiving traces, and the sensor bars are coupled to the control circuitry via the transmitting traces. Peripheral sensor bars are disposed over the receiving traces such that the receiving traces can be routed within an active portion of the borderless touchscreen panel without obstructing its touch-detection capabilities. Furthermore, the receiving traces are comprised of a transparent material such as indium tin oxide, and therefore do not obstruct the display capabilities of the active portion. Thus, there is no need for an inactive border region since the receiving traces are disposed within the active portion without obstructing either the touch-detection or display capabilities of the borderless touchscreen panel.

Abstract: A touch screen system is configured to sense a proximate or actual touch made to a touch screen panel. In response thereto, an RF transmitter is actuated to emit RF energy. A stylus receives the emitted RF energy and includes an RF energy harvesting circuit that powers an enable circuit. The enable circuit generates an enable signal. The stylus responds to the enable signal by performing a sensing operation. The information collected in the sensing operation is then communicated over an RF communications link back to the touch screen system. The sensing operation preferably is a pressure sensing operation for detecting an applied pressure at an end of the stylus resulting from contact with the touch screen panel.

Abstract: A display screen is configured to display information with a selectable one of many information display orientations. A touch screen panel of a touch screen system is positioned to overlie the display screen. The touch screen system operates to make a proximate touch detection, for example by a body part or stylus. A controller receives the proximate touch information from the capacitive touch screen system and interprets the proximate touch information to determine an indication from a user of a selection of an information display orientation for the display screen. The controller then controls the display screen to present information in accordance with the user selected information display orientation. The user selected information display orientation via the proximate touch detection will over-ride any other selected information display orientation such as a selection made in response to an orientation identified by an accelerometer or other gravity influenced sensor.
