  • Patent number: 8270494
    Abstract: A method for concatenating MPEG-4 or H.263 segments is provided. The method includes extracting and comparing the VOL or picture header information of each segment. If the two segments have the same VOL or picture header information, the method merges the two segments directly by appending one segment to another to form a new bit stream. If the two segments have the different resolution, the method completely decodes and re-encodes the segments and then merges the segments. Otherwise the method takes the VOL or picture header information of one segment as reference to produce the new bit stream. The method parses the other segment frame at a time, re-encapsulates it according to the reference VOL or picture header information, and appends it to the one segment. During the process, the method only uses VLD to parse the other segment without using the tools of DCT, IDCT, ME, and MC.

  • Patent number: 8246447
    Abstract: A game variation played on a gaming device displaying reels is disclosed. The game grants awards to the player for certain combinations of symbols. When a player gets one or more special symbols in an initial game, the player gets a free spin of one or more reels while the reels that display the special symbols are held. The player continues to get free spins as long as additional special symbols are displayed after each spin. The player may be granted awards for winning symbols combinations after each spin. In one embodiment, a certain number of special symbols across a payline awards the player a jackpot. In another embodiment, the game is a bonus game where any reels containing special, or trigger, symbols are shifted by one position after each free spin and then held for the next free spin. Only reels that do not display a trigger symbol are spun. The bonus game ends when there are no more trigger symbols displayed. The game may be played on a video gaming machine or a motor-driven reel machine.

  • Patent number: 8225558
    Abstract: A conventional grounded steel tower, or other structure, supports multiple wires (e.g., 6) carrying multi-phase high voltage electricity (e.g., >100 kV). Each wire is supported by a ceramic insulator connected to a horizontal arm of the structure, where an angled strut helps support the arm. There are usually three tiers of wires. The closest distance between a wire and ground is typically between the wire and an angled strut below the wire, where the angled strut helps support a lower-tier wire. A guard formed of a dielectric is affixed to and covers the lower portion of the steel strut as well as any steel that outward extends beyond the strut. The guard prevents flashover between a wire and the underlying grounded strut if a large bird perches on the guard, since the bird will not be grounded by the strut.

  • Patent number: 8219308
    Abstract: An engine-propelled monowheel vehicle comprises two wheels, close together, that circumscribe the remainder of the vehicle. When the vehicle is moving forward, the closely spaced wheels act as a single wheel, and the vehicle turns by leaning the wheels. A single propulsion system provides a drive torque that is shared by the two wheels. A separate steering torque, provided by a steering motor, is added to one wheel while being subtracted from the other wheel, enabling the wheels to rotate in opposite directions for turning the vehicle at zero forward velocity. The vehicle employs attitude sensors, for sensing roll, pitch, and yaw, and an automatic balancing system. A flywheel in the vehicle spins at a high rate around a spin axis, wherein the spin axis is rotatable with respect to the vehicle's frame. The axis angle and flywheel spin speed are continually adjustable to generate torques for automatic balancing.

  • Patent number: 8208816
    Abstract: An optical communications system includes an optical transmitter that generates a modulated optical signal at an output. The modulated optical signal propagates through an optical link where the dispersion of the optical link is imprinted onto an optical spectrum of the modulated optical signal. A demodulator receives the modulated optical signal and filters at least a portion of the optical spectrum with the imprinted dispersion of the optical link, thereby mitigating effects of dispersion in the modulated optical signal and generating a demodulated optical signal at an output. An optical detector generates an electrical data signal from the demodulated optical signal.
