Abstract: A clock generation circuit is provided for improving the accuracy of a low power oscillator circuit contained therein. The clock generation circuit includes a crystal-less oscillator having at least two distinct frequency modes, including a low frequency mode and a high frequency mode. In some cases, the crystal-less oscillator may be adapted to generate a first clock frequency with relatively high accuracy and a second clock frequency with relatively low accuracy. A calibration and control circuit is included within the clock generation circuit for increasing the accuracy of the second clock frequency. In particular, the calibration and control circuit increases accuracy by using the first clock frequency to calibrate the second clock frequency generated by the same crystal-less oscillator. A system comprising the clock generation circuit and methods for operating a crystal-less oscillator having at least two distinct frequency modes are also provided herein.

Abstract: Electromagnetic signals are sent between a base station and a human interface device (HID). Movements of the HID are detected according to an amount of time required for the electromagnetic signals to return back from the HID. In one embodiment, the electromagnetic signals are radio frequency (RF) waves carrying one or more pulses that are sent by multiple antennas in the base station and returned back from multiple antennas in the HID.

Abstract: An improved key matrix scanning technique conducts a first pre-scan on a first array of connections in a key matrix to identify any activated keys or buttons associated with the first array. A second sub-scan is conducted on a second array of connections in the key matrix but only for the connections in the first array that are detected as having activated keys.

Abstract: A wireless Universal Serial Bus (USB) device enumerates one or more real or virtual hubs that support transmission of USB data over a wireless network. The number of virtual hubs presented to a USB host can be varied dynamically according to monitored characteristics of the wireless network, such as the propagation delay, Bit Error Rate, or USB configuration of the peripheral device. Another aspect of the wireless system varies a USB transmission rate according to the amount of bandwidth available on the wireless network.

Abstract: A method may include generating display driver signals that vary between only two levels and applying the display driver signals to opposing electrodes of a display segment within a display device. The method varies a correlation between the display driver signals to select or de-select the display segment based on an average voltage magnitude across the display segment over a time period. The display segment is activated when the average voltage magnitude exceeds a threshold value.
