    Abstract: Multi-touch touch-sensing devices and methods are described herein. The touch sensing devices can include multiple sense points, each located at a crossing of a drive line and a sense line. In some embodiments, multiple drive lines may be simultaneously or nearly simultaneously stimulated with drive signals having unique characteristics, such as phase or frequency. A sense signal can occur on each sense line that can be related to the drive signals by an amount of touch present at sense points corresponding to the stimulated drive lines and the sense line. By using processing techniques based on the unique drive signals, an amount of touch corresponding to each sense point can be extracted from the sense signal. The touch sensing methods and devices can be incorporated into interfaces for a variety of electronic devices such as a desktop, tablet, notebook, and handheld computers, personal digital assistants, media players, and mobile telephones.

    Abstract translation: 这里描述了多触摸触摸感测装置和方法。 触摸感测装置可以包括多个感测点，每个感测点位于驱动线和感测线的交叉处。 在一些实施例中，多个驱动线可以同时或几乎同时受到具有独特特征的驱动信号（例如相位或频率）的刺激。 感测信号可以在可以与驱动信号相关联的每个感测线上发生存在于对应于被刺激的驱动线和感测线的感测点处的触摸量。 通过使用基于唯一驱动信号的处理技术，可以从感测信号中提取对应于每个感测点的触摸量。 触摸感测方法和装置可以并入用于各种电子设备的接口，例如台式机，平板电脑，笔记本电脑和手持式计算机，个人数字助理，媒体播放器和移动电话。

    Abstract: Liquid crystal display (LCD) touch screens integrate touch sensing elements with display circuitry and may include in-plane-switching (IPS) LCDs. A method of operating the integrated touch sensing elements with the display circuitry includes dividing touch-sensing circuitry of the touch screen into a plurality of drive segments, each drive segment overlapping one or more display rows; updating the display at a predetermined refresh rate; stimulating the plurality of drive segments at a predetermined scan rate; and changing the sequence of stimulating the plurality of drive segments as required to prevent simultaneously stimulating a drive segment that overlaps a display row currently being updated.

    Abstract: Disclosed is a compact, multi-user magnetic tracking system. In an embodiment, a compactness is achieved by using a single coil and inertial sensors at the transmitter and magnetometers and inertial sensors at the receiver for sensing the magnetic field generated by the single coil and for determining a position and attitude of the receiver relative to the transmitter. The transmitter and receiver each include a wireless transceiver for exchanging clock synchronization data and sending transmitter attitude data to the receiver. In another embodiment, frequency or time division multiplexing is used to differentiate between multiple users of the multi-user magnetic tracking system.

    Abstract: A touch sensitive mechanical keyboard configured to enable a standard look and feel mechanical keyboard to sense fine hand/finger motion over the surface of the keys. Command and cursor input (e.g., pointing and gestures) can be received from the user on the touch sensitive mechanical keyboard without requiring the user to move the user's hand off the keyboard. Fine hand/finger motion detection can be enabled by embedding clusters of capacitive sensors near the surface of the keyboard's keys. The touch sensitive mechanical keyboard can operate in two or more modes—e.g., a typing mode and a mouse mode—and operating the keyboard in mouse mode or switching between the modes can be facilitated by holding (depressing and holding) or tapping (depressing and releasing) arbitrary combinations of keys, or by detecting the number of fingers touching the touch sensitive mechanical keyboard.

    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: 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.
