摘要： Capacitive proximity sensing is carried out by detecting a relative change in the capacitance of a “scoop” capacitor formed by a conductor and a surrounding ground plane. Charge is transferred between the “scoop” capacitor and a relatively large “bucket” capacitor, and a voltage of the bucket capacitor is applied to an input threshold switch. A state transition (e.g., from low to high, or high to low) of the input threshold switch is detected and a value (TouchVal) indicative of a number of cycles of charge transfer required to reach the state transition is determined. The presence or absence of an object or body portion in close proximity to or contact with a device can be determined by comparing TouchVal with a predetermined threshold value (TouchOff). In order to lessen the time required for detection, and/or improve the sensitivity thereof, the bucket capacitor may initially be charged to a repeatable non-zero reference level closer to the charge level that will cause a state transition. TouchOff can be adjusted to take into account environmentally induced (non-touch related) changes in the capacitance of the scoop capacitor. Power management may be provided in a user operated data input device utilizing the inventive proximity sensing.

摘要翻译：通过检测由导体和周围地平面形成的“勺”电容器的电容的相对变化来进行电容接近感测。在“勺”电容器和相对较大的“桶”电容器之间传送电荷，并且将桶式电容器的电压施加到输入阈值开关。检测输入阈值开关的状态转换（例如，从低到高或高到低），并且确定指示达到状态转换所需的电荷转移周期数的值（TouchVal）。可以通过将TouchVal与预定阈值（TouchOff）进行比较来确定与设备紧密接触或接触的物体或身体部分的存在或不存在。为了减少检测所需的时间和/或提高其灵敏度，桶式电容器可以最初被充电到更接近导致状态转换的充电电平的可重复非零参考电平。可以调整TouchOff以考虑到勺式电容器的电容的环境诱导（非触摸相关）变化。可以在利用本发明的接近感测的用户操作的数据输入装置中提供电源管理。

摘要： A pointing device is provided for reporting motion information about the pointing device. Counts representing movement in two dimensions are processed so that a packet data stream may accommodate the motion information. One aspect of the invention utilizes the value of count to determine whether compression of the motion information should be performed. When it is determined that compression should be performed, a compression function is selected, the count is processed by the compression function, and an indicator is set to indicate that the count is processed by the compression function. Reporting information, which includes the processed count and the indicator, is then transmitted to computer system. A user input interface that is associated with the computer system recovers the counts using appropriate inverse functions in accordance with the indicators.

摘要： Interference between collocated wireless devices sharing the same RF channel is avoided or minimized by a new header format provided for the first data packet in an RF transmission. By inclusion of an invalid pulse in the header of each isolated data packet, an FM receiver that “captures” a desired signal from a closest device, midstream of processing an undesired signal (pertubation) from a more distant collocated device, is caused to abort the invalid packet and reinitialize. The receiver is then able to properly process the first packet in the desired transmission (from the closest device).

摘要： The present invention provides a system and method for conserving power consumption of a wireless device such as a BLUETOOTH slave device. A master device polls a slave device in a polling period. The slave responds by transmitting a data packet. If there is an error in transmission of the data, the master device may transmit an ARQ (Automatic Repeat Request) to the slave device in a TIMEOUT period to indicate that the data packet was not received. The slave device may reduce power consumption or power off during that TIMEOUT and receive a retransmit ARQ in a subsequent polling period.

摘要： The present invention reduces adjacent channel interference for a wireless peripheral device. A direct digital synthesizer generates a waveform having intermediate angular changes during a transition time between symbol intervals. After the transition time, the direct digital synthesizer generates the waveform with an angular value that corresponds to the symbol being transmitted. In an exemplary embodiment, a generated waveform is characterized by one of two designated frequencies in response to a value of an input information bit. The waveform is further characterized by at least one intermediate frequency during a transition time between a change of the designated frequency. Another embodiment of the invention utilizes phase changes rather than frequency changes during reduce adjacent channel interference. With another aspect of the invention, methods are provided to determine waveform parameters for reducing adjacent channel power (ACP) to a maximum level of interference.
