Abstract: The description relates to device pairing. One example can involve a computing device (e.g., companion device) and a stylus. The companion device can have a display and be configured to communicate in accordance with a wireless protocol. The stylus can be configured to transmit proximity information to the computing device when a user brings a tip of the stylus proximate to the display and be configured to supply wireless protocol identification information with the proximity information. The computing device can be configured to pair with the stylus over the wireless protocol using the wireless protocol identification information without requiring any additional action from the user on the computing device or the stylus.

Abstract: Devices are described herein that include an electrode having a thickness to, among other things, facilitate tracking. For example, the thickness of an electrode that is included in a device may be configured to cause a midpoint of a projection of the electrode on a sensor matrix to track a point on the device (or on a portion thereof, such as the electrode) that is closest to the sensor matrix. In another example, the thickness may be configured to cause a location of the electrode that is detected by the sensor matrix to track a point on the device (or on a portion thereof, such as the electrode) that is closest to the sensor matrix.

Abstract: A stylus pen is disclosed that can be used as an input device to a digitizer associated with a computer screen on a computing device, such as a computer, mobile device, tablet, etc. The stylus pen can include a voltage boost circuit that generates a stylus output signal on an antenna output. The voltage boost circuit has a charging portion and a discharging portion. Both portions have transistors that are activated and deactivated through pulsed control signals. However, a pulse duration for each control signal is separately controllable through different RC-based circuits. Additionally, the voltage boost circuit provides power savings by draining the output voltage signal to a positive voltage rail, rather than ground.

Abstract: A system and method for detecting electrical idle in a receiver is disclosed herein. A receiver includes a differential receiver, an analog idle detector, and a first filter. The differential receiver receives a variable rate differential signal. The analog idle detector is coupled to the differential receiver. The analog idle detector provides a first idle signal that erroneously identifies a differential signal electrical idle state. The first filter is coupled to the analog idle detector. The first filter processes the first idle signal and generates a second idle signal lacking the idle state errors of the first idle signal. The first filter provides the second idle signal to receiver control logic that controls signal reception.

Abstract: A system is provided, the system includes a phase-locked loop (PLL) that multiplies a reference clock input to generate a communication link clock signal. The system also includes a transmitter/receiver (TX/RX) module coupled to the PLL, the TX/RX module is configured to transmit and receive data based on the communication link clock signal. The system also includes a divider coupled to the PLL, the divider receives the communication link clock signal and outputs a PLL-adjusted reference clock that approximates the reference clock input. The PLL-adjusted reference clock is used to generate at least one other communication link clock signal.
