  • Patent number: 8123365
    Abstract: A one-way display system includes a transparent screen and a transparent color filter. An image is emitted by the screen or projected onto the screen. The image is formed from a combination of colored lights. Instead of spanning all the wavelengths of each color, each light only spans a narrow band of the color. The color filter removes the narrow band so the image is only visible from one side of the screen. As the color filter removes only the narrow band, one can still look out and see objects on the other side of the screen minus the colors of the narrow band.

  • Patent number: 8120105
    Abstract: A method of forming a lateral DMOS transistor includes performing a low energy implantation using a first dopant type and being applied to the entire device area. The dopants of the low energy implantation are blocked by the conductive gate. The method further includes performing a high energy implantation using a third dopant type and being applied to the entire device area. The dopants of the high energy implantation penetrate the conductive gate and is introduced into the entire device active area including underneath the conductive gate. After annealing, a double-diffused lightly doped drain (DLDD) region is formed from the high and low energy implantations and is used as a drift region of the lateral DMOS transistor. The DLDD region overlaps with the body region at a channel region and interacts with the dopants of the body region to adjust a threshold voltage of the lateral DMOS transistor.

  • Patent number: 8100764
    Abstract: A secure smart card or other secure modular memory device is plugged into (or otherwise connected to) a port of a game controller board internal to a gaming machine, where it is not accessible to a player. The smart card is programmed to detect an encrypted “challenge” message from the host CPU and output an encrypted “response.” If the host CPU determines that the response has the expected properties, then the host CPU verifies that the game program (an application program) is also is authentic, and the game can be played. The challenge/request exchange may be performed periodically to ensure the smart card is still installed. If the response is improper, then the host CPU will issue a halt command to halt play of the game.

  • Patent number: 8092659
    Abstract: A multi-chamber processing system is described for depositing materials on multiple workpieces (wafers, display panels, or any other workpieces) at a time in a vacuum chamber. The system includes a sputtering chamber and a separate pre-clean chamber, where wafers can be transferred between the two chambers by a robotic arm without breaking a vacuum. The wafers are mounted one-by-one onto a rotating pallet in the pre-cleaning chamber and sputtering chamber. The pallet is firmly fixed to a rotatable table in the sputtering chamber. Copper tubing in the table couples RF energy to the wafers, and a liquid running through the copper tubing controls the temperature of the wafers. Multiple targets, of the same or different materials, may concurrently deposit material on the wafers as the pallet is rotating. Multiple magnets (one for each target) in the magnetron assembly in the sputtering chamber oscillate over their respective targets for uniform target erosion and uniform deposition on the wafers.

  • Patent number: 8094892
    Abstract: A method determining image orientation includes determining if an image includes an orientation tag and if the tag indicates the image is rotated +90 or ?90 degrees. When the image does not include the tag or the tag does not indicate the image is rotated, the method includes determining if a face is detected in the original image and displaying the original image when a face is detected. When a face is not detected, the method includes rotating the image +90 and ?90 degrees and detecting a face in the rotated images. When a face is not detected, the method includes applying a classifier to determine the image's proper orientation. When a face is detected in one rotated image, the method includes displaying the rotated image. When a face is detected in both rotated images, the method includes applying the classifier to determine the image's proper orientation.

  • Patent number: 8085005
    Abstract: In an average-current mode control type buck-boost PWM converter, a sample and hold circuit is inserted in the current loop to avoid problems associated with ripple of the average inductor current demand signal. The rippling average inductor current is generated by a differential transconductance amplifier having applied to its inputs an error signal and a signal corresponding to the instantaneous current through the inductor, where the output of the amplifier is filtered. The rippling average inductor current is sampled and held at the beginning of each switching cycle, prior to the average inductor current demand signal being compared to buck and boost sawtooth waveforms. By using the sample and hold circuit, the feedback loops are easier to stabilize, and the converter cannot switch modes during a switching cycle.

  • Patent number: 8076181
    Abstract: A packaging technique is described for QFNs, DFN, and other surface mount packages that allows the sides of leads to be plated with a wettable metal prior to the lead frames being singulated from the lead frame sheet. The leads of the lead frames in the sheet are shorted together and to the body of the lead frame sheet by a sacrificial interconnect structure. Chips are mounted to the lead frames and encapsulated, leaving the bottoms of the leads exposed. The lead frame sheet is then sawed along boundaries of the lead frames but not sawed through the interconnect structure. The sawing exposes at least a portion of the sides of the leads. The leads are then electroplated while the leads are biased with a bias voltage via the interconnect structure. After the plating, the lead frame sheet is sawed completely thorough the interconnect structure to singulate the lead frames and prevent the interconnect structure from shorting the leads together.

  • Patent number: 8070584
    Abstract: In one embodiment, the invention is a secondary game played concurrently with a conventional Keno game. In Keno, a player selects a plurality of numbers (e.g., 4-20) within an M×N grid (e.g., 8×10) of different numbers. A random number generator randomly selects a plurality of numbers (e.g., 20) in the grid. The player is then granted a first award based on matches between numbers that the player selected and the randomly selected numbers. As a secondary game played over the Keno game, for each number randomly selected, all numbers in the same row and column in the grid as the selected number are highlighted on the grid display. The player is granted a second award (e.g., free games) for each number not being in a highlighted row or column at the end of the Keno game. Variations of the secondary game are described.

  • Patent number: 8070580
    Abstract: Upon a trigger event occurring during a main game on a video slot machine, a number of free games having a special feature are awarded to the player. For each trigger event that occurs during the free games, the lowest value symbol displayed for each free spin becomes a wild symbol or other high value symbol. The converted symbols remain converted during the entire free game session in one embodiment. In another embodiment, the converted symbols revert back to the original symbol if no further trigger event occurs in the free games. The accumulation of high value symbols over multiple spins increases the chances of the player winning an especially large award, such as a jackpot.
