摘要:
An apparatus for generating navigation information indicative of translational movement of a stylus including a ball rotatably mounted at an end of the stylus, a sensor system and a processor. The ball has an orientation-indicating property and the sensor system is arranged to sense the orientation-indicating property of the ball. The processor is coupled to the sensor system. In response to successive sensings of the orientation-indicating property, the processor is operable to determine changes in the orientation of the ball and to derive the navigation information from the orientation changes.

A computing device configured to communicate with an input device. The computing device includes a processor, a touch interface, such as a touch screen, and a receiving unit. The touch interface is configured to detect an input signal corresponding to an object approaching or contacting a surface. The receiving unit is configured to receive, through the touch interface, at least one input signal from the input device, and the receiving unit amplifies the at least one input signal creating at least one amplified input signal. Additionally, at least one of the processor or the receiving unit analyzes the at least one amplified input signal and creates at least one output digital signal corresponding to the at least one input signal.

An input device includes a positioning element and a spring member. The positioning element comprises a generally disc shaped member. The spring member is a generally annular shaped spring member that is generally planar and that defines a generally serpentine pattern. The spring member is positioned laterally outward relative to the positioning element and is configured to exert a biasing force radially inwardly toward the positioning element.

Stylus orientation detection is disclosed. In an example, the orientation of a stylus relative to a contacting surface, e.g., a touch panel, can be detected by detecting a capacitance at one or more locations on the stylus relative to the surface, and then using the capacitance(s) to determine the orientation of the stylus relative to the surface. In another example, the orientation of a stylus relative to a contacting surface, e.g., a touch panel, can be detected by first detecting the orientation of the stylus relative to a reference, detecting the orientation of the contacting surface relative to the reference, and then calculating the orientation of the stylus relative to the contacting surface using the two detected orientations.

This relates to compensation for undesirable capacitance changes in a touch sensing device, where the capacitance changes are not indicative of a touch at the device. The touch sensing device can include a touch sensor panel having touch sensors for sensing a touch at the panel, a flexible circuit for transmitting the sensed touch signal from the panel, and a touch controller for receiving and processing the transmitted signal. To compensate for the capacitance changes, the touch sensing device can include one or more reference conductive traces decoupled from touch sensors of the device to measure non-touch capacitances in the device. The touch sensing device can then adjust a touch signal from the touch sensors using the non-touch capacitance measurements to substantially reduce or eliminate the non-touch capacitances from the signal.

According to one embodiment, there is provided a mutual capacitance touchscreen or touchpad having combined finger navigation and stylus navigation and/or character entry capabilities. First and second pluralities of sense and drive electrodes are disposed in or on upper and lower substrates. The sense and drive electrodes form an array disposed substantially in two opposing planes that are configured to permit at least one location corresponding to a finger or stylus placed in proximity thereto to be detected thereby. The upper substrate is deflectable towards the lower substrate when the stylus is pressed downwardly thereagainst.

Fabrication of a touch sensor panel using laser ablation is disclosed. The fabricated touch sensor panel can have its touch sensors formed from conductive layers disposed on a surface such as an undersurface of the panel's cover substrate. A fabrication method can include ablating a first conductive layer to define the first part of the touch sensors and then ablating a second conductive layer proximate to the first conductive layer to define the second part of the touch sensors. The touch sensor panel can be incorporated into a mobile telephone, a digital media player, or a personal computer.
