Abstract: A method of displaying content to a user within a managed space comprised of one or more touch-free interactive kiosks includes collecting user data about the user. In addition, the plurality of touch-free interactive kiosks are configured to uniquely identify users located at the kiosk. Based on the identified user, and collected user data associated with the user, content is selected to be displayed to the user.

Abstract: A capacitive touch panel is tested for the presence or absence of short and open circuits in drive and sense lines without the use of a tool that touches the surface of the panel. During a first stage of testing, drive lines of the touch panel are sequentially driven while the remaining drive lines are floated. Sense lines are read to indicate whether a driven drive line is shorted to an adjacent drive line, an open circuit, or coupled to a sense line that is an open circuit. During a second stage of testing, drive lines are driven while alternate sense lines are floated or enabled. The signals on the enabled sense lines are acquired to indicate whether the enabled sense lines are shorted to adjacent sense lines. This second stage can be repeated, switching the roles of the sense lines, to determine the locations of short and/or open circuits.

Abstract: Apparatuses and methods of synchronizing a display driver integrated circuit (DDI) and a touch screen controller (TSC) integrated circuit that are coupled to a display integrated touch panel, such as an in-cell panel, and allowing multi-phase transmit (TX) scanning of the in-cell touch panel. One apparatus includes a DDI configured to receive signals on a video interface from a host processor over a video interface and to drive electrodes of a touch panel. The DDI is configured to receive control signals from a TSC over a control interface to drive different transmit (TX) phase sequences of a TX signal in different sensing interval on the electrodes of the touch panel.

Abstract: A haptic feedback system includes a user interface device, such as a touchscreen that includes a touch panel and one or more haptic drive elements coupled to the touch panel, a touch controller, and an actuator controller. The touch controller receives sensed data from the touch panel, and in response generates and sends a haptic signal to an actuator controller. Generation and transmission of the haptic signal bypasses any system host controller. A dedicated signal path couples the touch controller and the actuator controller, over which the haptic signal is transmitted. Alternatively, the haptic signal is transmitted from the touch controller to the actuator controller over a serial bus interface. In response to the received haptic signal, the actuator controller implements an appropriate drive signal in the form of a haptic waveform to the one or more haptic drive elements of the touchscreen.

Abstract: In one embodiment, an antenna enclosure associated with a satellite antenna may include a converter to downconvert incoming radio frequency (RF) signals from a first frequency to a second frequency, a receiver to receive the second frequency signals and to tune to at least one requested signal channel, and a wireless interface to receive and wirelessly transmit the at least one requested signal channel.

Abstract: A display timing generator is provided for selecting line types and providing synchronization timing signals for video signals. The display timing generator provides programmability for the user to select line types for a frame to be displayed on a display. The line types defining rise and fall times, synchronization shapes, blanking levels and horizontal and vertical timings for providing a desired display format to different display types. A plurality of programmable parameters for pulse width, horizontal timing and voltage amplitude allow a user to define timing variations associated with a given line type. The display timing generator also includes a generic mode for allowing a programmer to select line types for particular groupings of lines.

Abstract: A system and method is provided for determining a logarithm of an input value and a system and method for determining an inverse logarithm for an input value. The system and method determine an integer value relating to the logarithm and performs a linear interpolation over a range relating to the integer value. A mantissa value is produced from the linear interpolation and corrected over one or more correction stages. The inverse logarithmic system and method receive an input value comprising an integer value and a mantissa value. The mantissa value is precorrected over one or more precorrection stages. The precorrected mantissa is then combined with a value related to the integer value and multiplied by a restoration factor to produce the inverse logarithm.
