Abstract:
This relates to an event sensing device that includes an event sensing panel and is able to dynamically change the granularity of the panel according to present needs. Thus, the granularity of the panel can differ at different times of operation. Furthermore, the granularity of specific areas of the panel can also be dynamically changed, so that different areas feature different granularities at a given time. This also relates to panels that feature different inherent granularities in different portions thereof. These panels can be designed, for example, by placing more stimulus and/or data lines in different portions of the panel, thus ensuring different densities of pixels in the different portions. Optionally, these embodiments can also include the dynamic granularity changing features noted above.
Abstract:
Touch sensitive mechanical keyboards and processes for detecting touch events and key depressions on the touch sensitive mechanical keyboard are provided. The touch sensitive mechanical keyboard can include a set of individually depressible mechanical keys having a touch sensitive area located on their surface. A touch sensor can be included to detect touch events on the surface of the mechanical keys. A keypad can also be included to detect a depression of the mechanical keys. The touch sensitive mechanical keyboard can further include a processor for distinguishing detected touch events from detected key depressions. The processor can generate either a key depression command or a touch event command.
Abstract:
A touch sensor panel configured to mitigate the effect of parasitic capacitance on the ability of a capacitive touch sensor panel to reliably detect touch and proximity events. The touch sensor panel includes circuitry that can electrically drive a set of conductive shields that partially encapsulate various conductive components of the touch sensor panel. The touch sensor panel can also include circuitry that work to calibrate the touch sensor panel against variations in signal phase due to a parasitic capacitance.
Abstract:
A touch sensor panel configured to detect objects touching the panel as well as objects that are at a varying proximity to the touch sensor panel. The touch sensor panel includes circuitry that can configure the panel in a mutual capacitance (near field) architecture or a self-capacitance (far field and super far field) architecture. The touch sensor panel can also include circuitry that works to minimize an effect that a parasitic capacitance can have on the ability of the touch sensor panel to reliably detect touch and proximity events.
Abstract:
A touch sensor panel including a plurality of drive lines crossing a plurality of sense lines, forming an array, is disclosed. The plurality of drive lines and the plurality of sense lines are formed by interconnecting a plurality of substantially transparent conductive sections having a first resistivity. A substantially transparent conductive material, with a second resistivity that is lower than the first resistivity, is deposited over at least part of at least one of the plurality of substantially transparent conductive sections of at least one of the plurality of drive lines and the plurality of sense lines. A second layer of the substantially transparent conductive material, with the second resistivity, can be deposited thereafter. At least one dummy section is disposed in an area of the touch sensor panel around the conductive sections of at least one of the plurality of drive lines and the plurality of sense lines.

A touch sensor panel configured to switch between a mutual capacitance near field sensing architecture and a self-capacitance far field sensing architecture. The touch sensor panel includes circuitry that can switch the configuration of touch electrodes to act as either drive lines in a mutual capacitance configuration or as sense electrodes in a self-capacitance configuration. The touch sensor panel also includes circuitry that can switch the configuration of touch electrodes to act as either sense lines in a mutual capacitance configuration or a sense electrode in a self-capacitance configuration.
Abstract:
Lock-out mechanisms for driver handheld computing devices. The lock-out mechanisms disable the ability of a handheld computing device to perform certain functions, such as texting, while one is driving. In one embodiment, a handheld computing device can provide a lock-out mechanism without requiring any modifications or additions to a vehicle by using a motion analyzer, a scenery analyzer and a lock-out mechanism. In other embodiments, the handheld computing device can provide a lock-out mechanism with modifications or additions to the vehicle, including the use of signals transmitted by the vehicle or by the vehicle key when engaged with the vehicle.
Abstract:
Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.
