  • Publication number: 20140092053
    Abstract: A display screen is configured to display information with a selectable one of many information display orientations. A touch screen panel of a touch screen system is positioned to overlie the display screen. The touch screen system operates to make a proximate touch detection, for example by a body part or stylus. A controller receives the proximate touch information from the capacitive touch screen system and interprets the proximate touch information to determine an indication from a user of a selection of an information display orientation for the display screen. The controller then controls the display screen to present information in accordance with the user selected information display orientation. The user selected information display orientation via the proximate touch detection will over-ride any other selected information display orientation such as a selection made in response to an orientation identified by an accelerometer or other gravity influenced sensor.

  • Publication number: 20140009430
    Abstract: A touch sensitive display includes a capacitive touch sensor configured to output capacitance values. A motion sensor makes a motion detection and generates a motion signal including a motion value indicative of sensed motion detection. A touch detection circuit is coupled to receive the capacitance values and motion values. The touch detection circuit processes the capacitance values to make a hovering detection and a touching detection with respect to the display. The touch detection circuit further generates an output signal including the motion value correlated in time with each of the hovering detection and touching detection. The output signal may be processed as a user interface control signal. The output signal may also be processed to determine an impulsive strength of the touching detection as a function of an elapsed time between hover and touch and the measured motion values.

  • Patent number: 8502801
    Abstract: A method of matrix sensing using delay-based capacitance sensing, including using X-axis lines as active lines for capacitance measurements and using Y-axis lines as a disturbance to identify the location of a touch in a key matrix is disclosed. A sensing signal is applied to the X-axis lines, and a disturbance signal is applied to the Y-axis lines. If a location is touched, cross-capacitance is reduced, which is measured by sweeping data along the X-axis lines.

  • Patent number: 8041803
    Abstract: A method and system for delivering digital files in a peer-to-peer network comprising a plurality of nodes including at least one server is disclosed. The network includes a plurality of files that are available for accessibility by the nodes in which respective fingerprints are computed for each of the files based on content of the files. The method and system include partitioning each of the files into a plurality of file chunks, and assigning an error detecting code to each of the chunks. The file is then transmitted to a first node from at least one other node by transmitting the chunks of the file to the first node. The method and system further include computing a new error detecting code upon receipt of each chunk by the first node, and comparing the new error detecting code to the assigned error detecting code to verify that each chunk has been transmitted correctly, whereby the entire contents of the file does not have to be received before the first node discovers that the file is corrupt.

  • Patent number: 7827667
    Abstract: A packaging arrangement for smoothly and conveniently providing small hardware items to an assembly line operator is described. The items are fastened onto a flexible band, lined up in the order in which they are to be installed on an article being assembled. The band is divided into equal segments defined by index marks, each segment containing the hardware items required for the assembly of one article. The items are fastened to the band off-line using securing features fashioned from the band itself in a manner and orientation by which each item can be plucked from the band with a tool that can grasp the item, pull it off the band, transport it to the article being assembled, and install it on the article without intermediate disengagement from the tool. The utilization of the band improves the productivity and reliability of manually assembled articles such as disk drives.

  • Publication number: 20100164757
    Abstract: A system and method for receiving character entries in mobile computer devices uses an improved keypad. The keypad uses a dual key press method in which each key of the keypad includes a unique key definition when it alone is pressed. Each of two adjacent keys of the keypad also include a unique key definition when the two adjacent keys are pressed at substantially the same time. A keypad controller receives inputs from the keys and decodes the single key entries and the dual key entries. The keypad occupies a relatively small keypad area while providing full size keys for the user. The keypad also has a mode key that enables a user to change the alphabet mode of the keypad to a numerical mode.

  • Patent number: 7747808
    Abstract: An electronic device, operating as a USB host, has an embedded processor and a system memory, connected by a memory bus. A host controller integrated circuit does not need to master the system memory, but instead acts purely as a slave. The embedded processor is then adapted to write the data to the host controller integrated circuit in the form of transfer-based transactions.

  • Publication number: 20090115740
    Abstract: Integration of a FIFO memory, FIFO threshold and a timer, along with the other components of a touch screen system allows the number of interrupts to the touch screen controller to be reduced while allowing all point data to be acquired and preserved. In the first touch-detect event, an interrupt is issued to inform the host. The touch screen controller then automatically acquires data as long as touch is detected without host intervention. A FIFO threshold defines the minimum number of data points in FIFO memory before it issues an interrupt to inform the host that data is ready to be fetched. The timer is started once touch is detected. On every single data acquired, the timer is reset. In the event where touch is no longer detected, the timer keeps on counting until the time-up limit is reached. In this event, the touch screen controller will issue an interrupt informing the host the pen is lifted. The host then checks whether there is still data left in FIFO memory to be read.
