Abstract: A system includes a touchpad sensor array, a touch circuit, and a proximity circuit. The touch circuit executes a touch mode configured to track the position of a user or conductive object on the touchpad sensor array by detecting a change in an electrical property of the touchpad. The proximity circuit executes a proximity detection mode configured to track the position of a user or conductive object near or proximate to the touchpad sensor array by detecting a change in an electrical property of the touchpad. The system is configured to switch from the touch mode to the proximity detection mode after a predetermined period of inactivity, where the proximity detection mode can operate at one or more reduced polling rates, resulting in a reduced overall power dissipation. The system is configured to switch back to the touch mode when activity is detected by the proximity circuit.

Abstract: Embodiments of the invention are directed to input devices configured for use with computing devices. The present invention relates to methods and devices for establishing, maintaining and managing, wireless connections with between an input device and one or more host devices that the input device is paired with. The input device may include sensory feedback indicating the host device actively paired with the input device, and may enable switching between host devices.

Abstract: An input device includes a housing for supporting a user's hand and a displacement sensor, mounted in the housing, for providing a displacement signal. The input device also includes a first portion of the housing operable to receive a first digit of the user and a first solid-state touch sensor disposed in the first portion and operable to detect movement of the first digit along the first portion. The input device further includes a second portion on the housing operable to receive a second digit of the user and a second solid-state touch sensor disposed in the second portion and operable to detect movement of the second digit along the second portion.

Abstract: A method of operating an input device in conjunction with a host device includes determining that the input device is in a stationary state and receiving a first signal from a first sense zone of the input device. The method also includes determining an input command based on determining that the input device is in the stationary state and the first signal and transmitting a signal associated with the input command from the input device to the host device.

Abstract: A touch sensor system includes a touch controller having a first connector and a second connector and multiple sensor zones. The touch sensor system also includes a plurality of drive lines connected to the first connector of the touch controller and to the multiple sensor zones and a plurality of sets of sense lines connected to the second connector of the touch controller. Each set of the plurality of sets of sense lines is connected to one of the multiple sensor zones.

Abstract: A method includes placing an input device in a passive mode of operation and periodically monitoring a displacement sensor of the input device, receiving an indication of displacement from the displacement sensor, and placing the input device in an active mode of operation characterized by a power consumption level. The method also includes determining a passing of a predetermined time period since receiving the indication of displacement, placing the input device in a second active mode of operation characterized by a second power consumption level less than the power consumption level, and periodically monitoring one or more of a plurality of touch sensors. The method further includes receiving an indication of input from the one or more of the plurality of touch sensors and placing the input device in the active mode of operation.
