Abstract: An input device is operable to detect input. The input device is a deflection based capacitive sensing input device. Deflection of a metal frame of the input device causes a change in capacitance that is used to control a function of an electrical device. The input device appears invisible because it is made of the same material as the housing it is contained in. Invisible backlit holes may make the input selectively visible or invisible to the user.

Abstract: The present disclosure addresses methods and apparatus facilitating capacitive sensing using a conductive surface, and facilitating the sensing of proximity to the conductive surface. The sensed proximity will often be that of a user, but can be another source of a reference voltage potential. In some examples, the described systems are capable of sensing capacitance (including parasitic capacitance) in a circuit that includes the outer conductive surface, and where that outer conductive surface is at a floating electrical potential. In some systems, the systems can be switched between two operating modes, a first mode in which the system will sense proximity to the conductive surface, and a second mode in which the system will use a capacitance measurement to sense contact with the conductive surface.

Abstract: The disclosure addresses a force sensor that is scalable in size and adaptable to a variety of form factors, including those suitable for use in an input device for a computer or other processing system, and in some cases including those of the configuration normally referred to as a computer mouse. The force sensor will include at least two structural members that are cooperatively attached one another as to be displaced from one another in response to a force acting upon one of the structural members. In some examples, the engagement between the two structural members will be specifically configured to allow such displacement in response to forces acting laterally on the force sensor. The force sensor will also include one or more sensing mechanisms to provide a measurement of the sensed deflection.

Abstract: Improved capacitive touch and hover sensing with a sensor array is provided. An AC ground shield positioned behind the sensor array and stimulated with signals of the same waveform as the signals driving the sensor array may concentrate the electric field extending from the sensor array and enhance hover sensing capability. The hover position and/or height of an object that is nearby, but not directly above, a touch surface of the sensor array, e.g., in the border area at the end of a touch screen, may be determined using capacitive measurements of sensors near the end of the sensor array by fitting the measurements to a model. Other improvements relate to the joint operation of touch and hover sensing, such as determining when and how to perform touch sensing, hover sensing, both touch and hover sensing, or neither.

Abstract: Systems and methods for controlling a navigational object (e.g., a cursor) using an input device are disclosed herein. A system in accordance with one embodiment includes a motion-based input device adapted to move relative to a surface. The input device has one or more force sensors capable of detecting forces acting upon the input device. The system may then move a navigational object displayed on a receiving device in relatively small increments or relatively large increments, depending upon the detected forces acting upon the input device.

Abstract: Signal processing for a touch and hover sensing display device is disclosed. A touch and hover sensing display device can include a sensing panel for sensing a touch or hover event, a display for displaying graphical information to select based on the touch or hover event, and a control system for processing a signal indicative of the touch or hover event. The control system can process the signal to determine to which display location a hovering object is pointing according to a profile of the object's shape. In addition or alternatively, the control system can process the signal to differentiate between a close small object and a distant large object so as to subsequently perform intended actions of the device based, at least in part, on the object distance and/or area (or size). The display can be positioned at a desirable distance from the panel so as to reduce interference from the display to the panel and avoid adverse effects on the signal.

Abstract: Systems and methods for using measurements of a lateral force applied to a motion-based input device are disclosed. The input device has a force detection module operable to detect lateral forces applied to the input device and generate force data representative of the applied lateral forces. The system also includes a processor coupled to the force detection module. The processor is operable to initiate an event based upon the force data.

Abstract: A method and apparatus for determining the speed and/or position of an input device from vibrational signals is disclosed herein. In one embodiment, a response spectrum is generated as the input device moves across a surface. Amplitude and frequency data associated with the response spectrum is analyzed to determine the magnitude of the velocity.

Abstract: Ground detection of a touch sensitive device is disclosed. The device can detect its grounded state so that poor grounding can be selectively compensated for in touch signals outputted by the device. The device can include one or more components to monitor certain conditions of the device. The device can analyze the monitored conditions to determine the grounding condition of the device. The device can apply a function to compensate its touch signal outputs if the device determines that it is poorly grounded. Conversely, the device can omit the function if the device determines that it is well grounded.
