A touch pad device and method for determining a position of an input object on the device uses multiple sensing electrodes to produce signals induced by mutual capacitive coupling that are dependent on which conductors of the device are being electrically contacted by the input object. These signals are then processed to determine the position of the input object on the touch pad device.

Various embodiments provide an enhanced mobile computing experience by providing an input device in a mobile electronic device that is configured to accurately and quickly re-center a button or other user interface while providing a sensation of enhanced tactile feedback to a user. The biasing force of a magnetic re-centering mechanism is employed to overcome frictional forces acting on the button during its travel forwards and backwards and tilting to insure that the button is returned quickly and accurately to a resting position. The magnetic re-centering mechanism has a low profile, and permits the input device and the mobile electronic device within which the input device is disposed to have small form factors.

A control and data entry device adapted for use in for electronic devices such as portable computers, PDA's, cell phones, MP3 players and the like. The control and data entry device includes a tiltable member or similar structure carrying an electrically conductive member spaced from multiple sense electrodes disposed on a circuit substrate. In one embodiment, capacitances between the electrically conductive member and the electrodes are measured to provide information concerning the tiltable member's orientation relative to the sense electrodes. The tiltable member may be manipulated by a users finger to tilt such member slightly and thereby effect scrolling functionality, thereby simulating the operation of circular capacitive touch pads known in the art. Switches may also be included, responsive to greater tilting of the tiltable member, thereby to effect clicking functionality. In some embodiments, a rotatable knob may be used to effect scrolling functionality.

A displaceable member moves in an operational zone over a sense system that includes a spatial arrangement of sense electrodes and at least one drive electrode. A conductive coupling element of the displaceable member capacitively couples signals from the at least one drive electrode to ones of the sense electrodes underlying the conductive coupling element. A measurement system generates measurement signals indicating amounts of overlap between the conductive coupling element and ones of the sense electrodes. A processing system produces from the measurement signals an output signal with information conveying motion measures corresponding to absolute positions of the conductive coupling element in the operational zone. At least one regional sense electrode may include discrete electrically conducting sensing elements distributed across a respective region of the operational zone. The drive electrode may include discrete electrically conducting sensing elements interspersed among the sensing elements of the at least one regional sense electrode.

In an input apparatus, an input system includes a displaceable member movable in an operational zone and a tracking surface that moves in correlation with movement of the displaceable member. An optical sensor has a field of view of at least a portion of the tracking surface during movement of the displaceable member in the operational zone and generates optical data in response to light received from the tracking surface. A processing system produces motion measures indicative of movement of the tracking surface from the optical data. In an input method, optical data is generated in response to light received from a field of view of at least a portion of a tracking surface that moves in correlation with movement of a displaceable member during movement of the displaceable member in an operational zone. Motion measures indicative of movement of the tracking surface are produced from the optical data.

A fingerprint sensing module for a touch screen device. The fingerprint sensing module includes a sensor, a light source, a motion detector, and an image processor. The sensor sets to capture portions for a fingerprint image as a finger is slid over the sensor. The motion detector determines a rate of the finger movement as the finger is slide over the touch screen device. The image processor reads fingerprint images from the sensor and the fingerprint motion data from the motion detector. The image processor subsequently combines portions of the fingerprint images into a complete fingerprint in accordance with the rate of the finger's movement.

Closed-loop printing registration systems (e.g., printers), devices, components and methods are provided. In one embodiment, a printer reproduces continuously and sequentially on a sheet of paper invisible ink landmarks that mimic registration information provided initially by permanent invisible ink markers disposed on a platform or platen. According to one embodiment, once the first row of invisible ink landmarks has been printed on a sheet of paper, the first and subsequent rows of invisible ink landmarks provide a basis for continuous registration and alignment of sheet of the paper as it is being printed upon and advanced through the printer. In other embodiments, one or two invisible ink landmarks dispensed on a sheet of paper, preferably in combination with a sensed edge or corner of a sheet of paper, provide sufficient information for a sheet of paper to be registered and aligned initially with respect to a print head or carriage, and for subsequent invisible ink landmarks to be deposited on the sheet of paper at locations which are determined.

In one embodiment, a mutual-capacitance sensing electrode array is disposed beneath a keyboard, and operates in conjunction with a series of single switches disposed beneath each of the keys in a keyboard. The electrode array and switches are employed in conjunction with one another to indicate that a letter, number or other symbol displayed on a particular key has been selected by a user. Although some embodiments find especially efficacious application in hand-held portable electronic devices such as mobile telephones, other embodiments are well suited for use in stationary equipment or other devices containing keyboards or control panels.
