  • Patent number: 9344055
    Abstract: Signal-processing devices having memristors are described for performing frequency-discrimination functions, amplitude-discrimination functions, and time-oriented functions. In each case, the time-domain behavior of the memristors described herein enables these functions to be performed. In one embodiment, memristance of an arrangement of memristors of a device is, after an initial transitional period, predominantly at a first level if frequency of an input signal of the device is less than a first frequency and predominantly at a second level if the frequency of the input signal is greater than a second frequency.

  • Patent number: 9318241
    Abstract: A high speed data cable carries high-speed and auxiliary signals, and includes a raw cable. The raw cable includes coaxial lines which are covered by an outer conductive shield. High-speed signals are carried on the inner conductors of a pair of coaxial lines. Lower speed signals are carried on the galvanically or capacitively coupled shields of a pair of coaxial lines, and/or the outer conductive shield.

  • Patent number: 9076575
    Abstract: A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable and a boost device. The raw cable is exclusively constructed with either Shielded Twisted Pairs (STP) or coaxial lines which carry all signals on either shielded wires or their shields. The high speed signals are carried on the shielded wires to the boost device where any common mode noise induced by the signals on the shields is removed. Some auxiliary signals including power are carried on ungrounded shields.

  • Patent number: 9040823
    Abstract: A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI) or DisplayPort standards, and includes a raw cable and a boost device. The raw cable includes coaxial lines of a characteristic cable impedance lower than the impedance implied in the standards. The correct impedance is observed at the sending end by series resistors mounted in the first cable connector. The resultant loss of signal is made up with the boost device mounted in the connector at the other end of the cable.

  • Publication number: 20150020009
    Abstract: The invention is directed toward a computer system and method for scrolling through a multiple number of display panels on the touch screen of an electronic device. The invention is directed toward a computer system and method to detect a tap on the touch screen interface within a predetermined area on the touch screen interface, detect a swipe gesture across the touch screen interface, perform a predetermined function changing the visual display output of the touch screen interface when the swipe gesture exceeds the boundaries of the predetermined area, and change the visual display output of the touch screen interface by moving a plurality of display panels across the touch screen interface in an opposite direction than the direction of the swipe gesture. The swipe gesture comprises an initial touchdown point within the predetermined area and a direction, and terminates outside of the predetermined area.

  • Publication number: 20140241440
    Abstract: A high speed video cable carries signals according to the High-Definition Multimedia Interface (HDMI), and includes a raw cable and may include a boost device. The raw cable includes coaxial lines which are covered by an outer metallic braid. Each of four high speed video signals is carried on the inner conductors of a pair of coaxial lines. Lower speed signals are carried on the galvanically or capacitively coupled shields of a pair of coaxial lines, as well as the braid of the cable, thus permitting fourteen HDMI signals to be carried in a cable comprising only eight coaxial lines, resulting in a simpler and lower cost production and assembly of the cable.

  • Patent number: 8520776
    Abstract: A high-definition multimedia interface (HDMI) receiver recovers high speed encoded data which are transmitted differentially over data channels of a lossy cable, along with a clock. Inter symbol interference, high-frequency loss, skew between the clock and data channels, and differential skew within a differential signal are compensated by analog circuits which are automatically tuned for best performance by observing the quality of the recovered analog signal. Oversampling is used to provide a 24-bit digital representation of the analog signal for determining the quality of the signal.

  • Patent number: 8437973
    Abstract: A self calibrating cable, including a USB3 cable, with a boost device of the embodiment of the invention is described, in which parameters that control the response of the boost device are set optimally in a self-calibrating process comprising looping the boosted cable on itself through a calibration fixture that contains a calibration control device. The boost device includes pattern generators and a sampling circuit. Each high speed channel of the cable is separately tested and calibrated with the help of one of the other channels serving as a sampling channel. Additional embodiments provide for a selected replica boost device and a distinct pattern generator device in the calibration fixture. A corresponding system and method for calibrating a cable are also provided.

  • Patent number: 8295296
    Abstract: An HDMI cable carries high speed encoded data which are transmitted differentially over data channels, along with a clock. High-frequency loss and differential skew within a differential signal may be compensated by analog circuits embedded in the cable. These embedded circuits are tuned at production for best performance by observing the quality of the recovered analog signal. The embedded circuits are powered by a combination of power sources, both carried within the cable, and harvested from the high-speed signals themselves.
