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： 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： 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： Disclosed are a unique system and method that facilitate establishing and maintaining a secure connection between at least one wireless input component and a host (e.g., PC). The system and method involve the wireless input component broadcasting a message that can be “heard” by any potential host located within a given distance from the wireless input component. The message can indicate that the input component is available for use or pairing with a PC. PCs in the area can respond to the message by notifying the user that a wireless input component is available and by generating a random PIN. The PIN can be displayed to the user on the respective PC. The user can be prompted to enter the PIN using the wireless device. When a match between the user's response and the corresponding PC is determined, the two can be securely linked. In addition the invention provides support of wireless input devices at boot or start up.

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. The conductor may be a plate provided in the form of an adhesive label printed with conductive ink. 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). TouchOff can be adjusted to take into account environmentally induced (non-touch related) changes in the capacitance of the scoop capacitor. Power management is provided in a user operated data input device utilizing proximity sensing and switching between three or more power states. Switching between the power states occurs based upon the presence or absence of input activity, and an operation instrumentality (e.g., a hand) in close proximity to or contact with the device. In an optical surface tracking cursor control device embodiment, switching to and from a BEACON state, which provides a reduced flash rate of a surface illuminating light source, is carried out based upon a detected presence or absence of a trackable surface.
