摘要： A touch sensor device (TSD) includes TSD electrodes associated with a surface of the TSD. Also, an overlay that includes marker electrode(s) is also associated with a region of the surface of the TSD. The TSD also includes drive-sense circuits (DSCs) operably coupled to the plurality of TSD electrodes. A DSC is configured to provide a TSD electrode signal to a TSD electrode and simultaneously to sense a change of the TSD electrode signal based on a change of impedance of the TSD electrode caused by capacitive coupling between the TSD electrode and the marker electrode(s) of the overlay. Processing module(s) is configured to process a digital signal generated by the DSC and other digital signals generated by other DSCs determine the region of the surface of the TSD that is associated with the overlay and to adapt sensitivity of the TSD within that region.

摘要： A rotating equipment system with in-line drive-sense circuit (DSC) electric power signal processing includes rotating equipment, in-line drive-sense circuits (DSCs), and one or more processing modules. The in-line DSCs receive input electrical power signals and generate motor drive signals for the rotating equipment. An in-line DSC receives an input electrical power signal, processes it to generate and output a motor drive signal to the rotating equipment via a single line and simultaneously senses the motor drive signal via the single line. Based on the sensing of the motor drive signal via the single line, the in-line DSC provides a digital signal to the one or more processing modules that receive and process the digital signal to determine information regarding one or more operational conditions of the rotating equipment, and based thereon, selectively facilitate one or more adaptation operations on the motor drive signal via the in-line DSC.

摘要： A method includes a first computing device generating a signal having an oscillating component and driving the signal on a first touch sense element of the first computing device. The method continues with the first computing device detecting a touch on the first touch sense element based on the signal. While the touch is detected, the method continues by the first computing device modulating the signal with data to produce a modulated data signal. The method continues with a second computing device receiving the modulated data signal via a transmission medium and a second touch sense element of the second computing device, where the transmission medium includes at least one of a human body and a close proximity between the first and second computing devices. The method continues with by the second computing device demodulating the modulated data signal to recover the data.

摘要： A method for execution by a Dynamic Random Access (DRAM) cell processing circuit, includes charging a bit-line operably coupled to a plurality of DRAM cells of a DRAM memory device, including a current DRAM cell, at a first voltage to pre-charge the parasitic capacitance between ground and the bit-line to a second voltage, where the second voltage is between a logic 1 voltage and a logic 0 voltage. The method continues by sensing a voltage change on the bit-line based on a difference between a voltage stored on a DRAM cell capacitor of the current DRAM cell and the second voltage and outputting a read output voltage that is generated based on the sensed voltage change. The method then continues by supplying, while outputting the read output voltage, the read output voltage to the bit-line to refresh the voltage stored in the DRAM cell capacitor of the current DRAM cell.

摘要： A method includes transmitting, by a touch screen device, signals on electrodes. The method further includes detecting, by a pen, a signal of the signals via an electrode of the electrodes. The method further includes creating, by the pen, a representation of the signal and transmitting the representation of the signal in accordance with a pen recognition signal format. The method further includes detecting, by the touch screen device, a change in the electrical characteristic of the electrode that is caused by the representation of the signal. The method further includes determining, by the touch screen device, that the pen is causing the change to the electrical characteristic of the electrode based on the pen recognition signal format.

摘要： A low voltage drive circuit (LVDC) operable to convey data via a bus and includes a signal generator operable to convert transmit digital data into analog outbound data. The LVDC also includes an analog to digital output circuit operable to convert analog inbound data into received digital data. The LVDC further includes a drive circuit operable to convert the analog outbound data into an analog transmit signal and drive the analog transmit signal on to the bus, where the analog outbound data is represented within the analog transmit signal as variances in loading of the bus at a first frequency. The LVDC further includes a sense circuit operable to receive an analog receive signal from the bus and convert the analog receive signal into the analog inbound data, where the analog inbound data is represented within the analog receive signal as variances in loading of the bus at a second frequency.

摘要： A method includes generating a voltage difference indication between a previous voltage on the bit line of a DRAM and a current voltage on a bit line. In an embodiment, the previous voltage corresponds to a logic 1 voltage or a logic 0 voltage stored in a previous DRAM cell of a column of DRAM cells, the current voltage corresponds to a logic 1 voltage or a logic 0 voltage being stored in the current DRAM cell of the column of DRAM cells, and the bit line is coupled to the column of DRAM cells. When the current DRAM cell is in a read mode, the method further includes the following steps: Generating a read voltage reference based on the voltage difference indication; Generating a read output voltage based on the read voltage reference; Supplying the read output voltage on to the bit line; and Outputting a representation of the read output voltage.

摘要： A method includes detecting, by a first LVDC affiliated with a first host device, a request for a one-to-one communication with a second LVDC affiliated with a second host device, where data is conveyed between the LVDCs by varying loading on a bus at a frequency. The method further includes determining a desired number of channels to support the one-to-one communication based on one or more of: the first host device, the second host device, and information contained in the request, wherein the channels correspond to frequencies in a frequency band. The method further includes determining whether the desired number of channels is available for the one-to-one communication. When the desired number of channels is available for the one-to-one communication, allocating them for the one-to-one communication.
