  • Publication number: 20110199226
    Abstract: A control indication assembly. A first control mounted on a surface of a computer is coupled to a first sensor, to a first sensing circuit to send an electrical signal to the first control when a user-touch occurs to the first sensor, and to a first indicator to indicate an occurrence of said user-touch. A second control mounted on a surface of a display which is coupled to the computer is coupled to a second sensor, to a second sensing circuit to send an electrical signal to said second control when said user-touch occurs to the display, and to a second indicator to indicate an occurrence of the user-touch. The first and second control are configured such that the first and second indicator are synchronized to exhibit identical behaviors when the user-touch occurs to either the first control or the second control.

  • Publication number: 20100201626
    Abstract: A mouse having improved input methods and mechanisms is disclosed. The mouse is configured with touch sensing areas capable of generating input signals. The touch sensing areas may for example be used to differentiate between left and right clicks in a single button mouse. The mouse may further be configured with force sensing areas capable of generating input signals. The force sensing areas may for example be positioned on the sides of the mouse so that squeezing the mouse generates input signals. The mouse may further be configured with a jog ball capable of generating input signals. The mouse may additionally be configured with a speaker for providing audio feedback when the various input devices are activated by a user.

  • Publication number: 20100060593
    Abstract: Determining a compensated phase matrix for a multi-stimulus demodulation process is provided. A first drive line of a multi-stimulus sensing system is selected, and a stimulation signal is transmitted on the selected drive line. A channel gain resulting from the stimulation signal is measured from a received sense signal resulting from the stimulation signal. The measured channel gain is compared with a known channel gain to obtain an individual phase compensation for the selected drive line. A compensated phase matrix is formed of the individual phase compensation values for multiple drive lines.

  • Publication number: 20090037819
    Abstract: An apparatus and method for handling special windows in a display comprises a window manager in an operating system that is called by application programs to create special windows. The window manager embeds static key signals including encoded special window information, such as the coordinates of a window area to be specially processed, into a video RAM. An existing video interface scans the video RAM and transmits display information, including the key signals, to the display. The present invention further comprises a window decoder in the display, that detects the key signals, extracts the encoded special window information, and controls display circuitry performing the desired special processing. The key signal encoding scheme does not create visually discernible display aberrations that could distract the user or interfere with normal window management.

  • Publication number: 20080165134
    Abstract: An embodiment of an improved touch surface controller for controlling a multi-point touch surface such as a touch screen or a touch pad in a computer system is disclosed. The improved touch system controller detects signal capacitance from the pixels in the touch surface digitally, and therefore is easier and simpler to implement then previous approaches relying on analog detection and processing. Specifically, signal capacitance is measured by measuring a number of clock cycles taken to discharge or charge the input node of a comparator. Embodiments of the disclosed touch surface controller are particularly useful in the context of detecting multiple simultaneous touches on the touch surface.
