Abstract: An apparatus includes multiple radio-frequency (RF) circuits, a number of Bluetooth (BT) cores and a processor. The BT cores are coupled to the plurality of RF circuits. The processor is coupled to the BT cores to control operations of the RF circuits and the BT cores. The RF circuits, the BT cores and the processor are implemented as a system on a chip (SoC). Controlling the operations of the RF circuits and the BT cores can be performed by controlling register spaces associated with the RF circuits and the BT cores.

Abstract: A system may include an adapter, a charger, and a connector. The adapter is configured to receive an alternating current (AC) signal and generate an adapter signal, the adapter signal being generated based on an up-conversion of the AC signal. The charger is configured to generate a direct current (DC) signal from the adapter signal using one or more energy storage elements and supply the DC signal to a load, in which the adapter signal has a voltage greater than that of the DC signal. The connector is configured to couple the adapter and the charger. In some aspects, the adapter signal is adjusted based on one or more measurements of the DC signal at an output of the charger to maintain a target power for charging the load.

Abstract: A device for detecting a short beacon signal includes a power-receiving unit (PRU) to receive the short beacon signal from one or more power-transmitting units (PTUs). An active load level is asserted for detection by the one or more PTUs in response to the short beacon signal. The active load level, once asserted, makes a detectable change in a reflected impedance associated with the PRU as measured by at least one of the one or more PTUs.

Abstract: Adaptive reconfiguration of a capacitive touch controller is implemented by estimating the interference spectrum of the signal received by the touch controller. The spectrum of the received signal is used to determine a desired frequency, and the touch panel transmitter is configured to use that desired frequency. The spectrum of the received signal is also used to determine an desired filter transfer function. A filter in the touch panel received signal path is configured to use that desired filter transfer function. The adaptive reconfiguration is focused on improving the signal to noise ratio of the received signal without the need for shielding the touch panel, performing additional scans of the touch panel, or using components that operate at higher power levels.

Abstract: Asymmetric scanning logic implements asymmetric panel scanning by scanning some rows on a touch panel more frequently than other rows. Note that although an entire row at a time may be driven, if only particular pixels in the row are of interest (e.g., included in any region of interest for focused asymmetric scanning), then circuitry may power down the receivers for the columns in which the pixels exist to save power. The asymmetric scanning logic facilitates focused attention to specific areas of interest on the touch panel, to compensate, for example, for high noise or low signal strength in those areas of interest.

The controller is operable, when the scanning logic is executed, to energize a first and a second row in the touch panel simultaneously, a first time; obtain a first signal measurement along a column intersecting the first and second rows; energize the first and the second row in the touch panel simultaneously, a second time; obtain a second signal measurement along the column; and determine a first pixel value and a second pixel value along the column from the first signal measurement and the second signal measurement.

Abstract: Aspects of the invention may comprise managing operations of BLE interfaces and/or other radio interfaces in a wireless device to mitigate interference to communication via the BLE interfaces by the other radio interfaces. Operating parameters may be communicated between the BLE interfaces and the other radio interfaces to enable mitigating the interference to the BLE interfaces, and at least some of the BLE interfaces and/or the other radio interfaces may be configured based on the communicated operating parameters. The operating parameters may comprise adaptive frequency hopping (AFH) maps that may be adjusted to prevent use of common and/or used channels. The communication device may detect energy associated with BLE communication via scan of all or some of channels used for BLE communication. BLE communication may be predicted based on monitoring of frequency bands used during BLE communication, and/or monitoring of events that may trigger and/or occur during BLE communication.

Abstract: A method of compensating for optical distortion on a display panel is provided. The method includes determining one or more pixels in a display that need compensation for optical distortion on a display panel. The method also includes generating a mapping of the display comprising location information of the one or more pixels determined to need optical distortion compensation. The method also includes generating a control signal based on the mapping to control one or more display characteristics of the one or more pixels. The control signal has scaled display values for the one or more display characteristics to reduce the optical distortion on the display panel. The method also includes outputting the control signal to the one or more pixels in the display.

Abstract: A time base management system facilitates early analysis, detection, and status messages (e.g., early warnings) concerning the operation of time bases in a device. In addition, the time base management system may adapt the time bases in the device according to the anticipated, selected, or actual operating conditions of the device. As one example, if the time base management system knows that a cell phone will switch to a high data rate (e.g., 4G or LTE) operation mode, the time base management system may configure a time base in the cell phone to operate with increased precision or accuracy, or otherwise meet any applicable time base operational profile for high data rate operation.

Abstract: A method for touch detection in a touch panel display includes entering a low power touch detection mode and intermittently stimulating the touch panel display with signals to determine if any touch event occurs without locating the touch event on the touch panel. If a touch event is detected, a full scan mode is entered to locate the touch event on the touch panel. This provides both faster touch detection and lower power operation for the touch panel display and controller circuit.

Abstract: A digital subscriber line (DSL) communication system that utilizes the high frequency band of a standard telephone line does not require the use of a plain old telephone service (POTS) splitter in the resident's home, which provided isolation between the POTS frequency band (0 to 4 kHz) and the DSL frequency band. A digital subscriber line modem utilizes either constant envelope modulation or quadrature amplitude modulation for outputting DSL signals upstream to a central office. When a telephone in the resident's home is detected as being off-hook, then the constant envelope modulation is used by the DSL modem in order to lessen the intermodulation product distortion that results in audible noise heard by a user of the telephone. When the telephone is on-hook, then another type of modulation, such as QAM, is used to maximize the upstream data rate capability in the DSL frequency band, since any noise generated by the QAM is not a problem due to the non-use of the POTS frequency band.
