Abstract: A mirror is shaped using a shaping apparatus including a crossbar and a horizontal array of members (wheels in some embodiments) attached to a bottom of the crossbar. The height of the array of members is adjusted to form a predetermined shape. The shaping apparatus is positioned over a mirror such that the members contact the mirror. The shaping apparatus is moved along a length of the mirror such that the members remain in contact with the mirror. A frame is attached to the mirror such that when the shaping apparatus is removed from the mirror, the mirror substantially retains the predetermined shape.

Abstract: A method for merging first and second images includes determining a pixel difference image from the first and the second images, determining first and second locations of the foreground subject from the pixel difference image, determining a minimum path of values from the pixel difference image for a region between the first and the second locations of the foreground subject, forming a merged image by stitching the first and the second images along the minimum path, and adjusting pixels of the merged image within a width of the minimum path.

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.

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.

Abstract: A method for forming a semiconductor device includes forming a nanotube region using a thin epitaxial layer formed on the sidewall of a trench in the semiconductor body. The thin epitaxial layer has uniform doping concentration. In another embodiment, a first thin epitaxial layer of the same conductivity type as the semiconductor body is formed on the sidewall of a trench in the semiconductor body and a second thin epitaxial layer of the opposite conductivity type is formed on the first epitaxial layer. The first and second epitaxial layers have uniform doping concentration. The thickness and doping concentrations of the first and second epitaxial layers and the semiconductor body are selected to achieve charge balance. In one embodiment, the semiconductor body is a lightly doped P-type substrate. A vertical trench MOSFET, an IGBT, a Schottky diode and a P-N junction diode can be formed using the same N-Epi/P-Epi nanotube structure.

Abstract: A casino resort management system collects patron data, manages patron data in a high performance data warehouse, shares patron data with other systems and reports vital patron information. The system particularly tracks machine history, including changes in location, configuration and performance, and tracks the location history, including game type and denomination, and allows for placards to be moved from one gaming machine to another without losing historical machine or location information. In addition, the system provides two particularly useful graphical displays that simplify visual analysis of the large amounts of data within a casino. One display method depicts tables of thin bar graphs that compactly allow side-by-side comparison of different groupings of machines and another display method depicts machines in three dimensions so that each dimension can provide visual information to a viewer.

Abstract: In one embodiment, a certain number of special games are granted to a player, or the special games are only enabled for a certain time period. The special games may be free bonus games or paid games. At the end (or beginning) of each special game, at least one position in the array of symbols is designated as a special symbol. The special symbol may be a wild card, a scatter symbol, a multiplier, or any other special symbol. The special symbol selected for a particular game is carried over into the next special game, so the special symbols are accumulated and remain in their positions in the array for the series of special games. Awards, if any, are granted after each game based on the use of the special symbol(s) in combination with other symbols across one or more pay lines. The special symbol position in the array (or the special symbol type) may be selected by the gaming machine or by the player. Other embodiments are disclosed where special symbols are designated by the gaming machine or the player.

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.

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.

Abstract: A hook and eye fastener includes a hook and an eye. The hook has a hook top plate and a hook base plate with a kinked end that curves toward the top plate and then curves away from the top plate. The kinked end is spring-loaded to rest on the hook top plate. The eye has an eye comprising a eye top plate and an eye base plate defining an opening for receiving the hook top plate. When the hook is initially inserted into the eye, the eye top plate pushes up against the kinked end of the hook base plate. When the kinked end slides past the eye top plate after the hook is fully inserted into the eye, the kinked end of the hook base plate snaps back down against the hook top plate and produces an audible sound to indicate the fastener is secured.

The peak detect circuit includes first and second diodes receiving the amplified signals from the gain stages to charge a peak detect capacitor. The signal detection circuit includes a comparator for comparing the voltage on the peak detect capacitor to a reference voltage and providing an output signal being indicative of the presence or absence of a signal on the first and second receive terminals of the Ethernet PHY device.

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.
