  • Patent number: 5710886
    Abstract: A method and apparatus for distributing, generating, and redeeming discount coupons, rebate or gift certificates or the like tracks each coupon using a consumer ID number printed on the coupon. Coupons may be distributed electronically, for example, in the form of a diskette or CD-ROM software. Software on the diskette or CD-ROM may prompt a consumer to call a 1-800 number for a validation number or code. During the phone call, telemarketing personnel may request consumer demographic and or identification information which may be entered into a centralized database. Once the software is validated, a consumer may print out selected coupons displayed on a Graphical User Interface (GUI). Each coupon may be printed only a limited number of times. Each coupon may be imprinted with a consumer ID number, preferably in the form of a bar code. Once redeemed, consumer ID information and coupon information may be retrieved from coupons forwarded to a coupon clearing house.

  • Patent number: 5703618
    Abstract: A graphics controller circuit for upscaling source video image to generate an upscaled video image. The graphics controller circuit generates additional pixel data for the upscaled video image by interpolating source video pixel data of a one scan line and an another scan line. However, when source video pixel data of the another scan line may not be available for interpolation, the graphics controller circuit generates additional pixel data from source video pixel data of only the one scan line. Source video pixel data of the another scan line may not be available, for example, as a bus that transfers the pixel data may not have sufficient amount of bandwidth.

  • Patent number: 5673400
    Abstract: An apparatus and method for controlling devices in a multiple bus system such as a system having two or more ISA type buses. Separate ISA bus controllers may be provided for each ISA bus, linked on a common bus system such as a PCI bus. One ISA controller may be designated as a primary ISA controller whereas other ISA controllers in the system may be designated as secondary ISA controllers. Each ISA controller in the system is provided with IRQ (interrupt request) enable bits to enable different interrupts for the corresponding ISA bus. Each secondary ISA controller outputs a signal IRQSER as a PCI sideband signal to the primary ISA controller to indicate which IRQs have been asserted on the respective ISA buses. The primary controller receives the IRQSER signal as well as the IRQ signals asserted on its own bus and converts these interrupt requests to PCI bus cycles.

  • Patent number: 5668941
    Abstract: A method and apparatus for improving performance of bit block transfers in display controllers during clipping functions without significantly increasing gate count. In a clipping function, particularly when transferring a portion of a monochrome bit map and color expanding same or in pattern copying, a source start address may not lie on a byte boundary. In order to avoid using time consuming shift left operations in software, the source start address may be adjusted in hardware to an earlier byte boundary. Upon writing data to a destination address, a hardware byte mask may be employed to prevent writing of the additional data retrieved due to the adjustment of the source start address. The source start address and byte mask hardware may be implemented in hardware using bit block transfer engine components and a small amount of additional hardware. The remainder of the clipping functions may remain in software, for example in a display device driver.

  • Patent number: 5630043
    Abstract: A method and apparatus for generating 3-D images utilizes an MPEG decoder to decode/decompress animated texture maps into a half-frame buffer. The MPEG decoder may act as a PCI bus master to assert control of the host system bus to the exclusion of all other system devices to transfer animated texture maps into an off-screen portion of video memory. A graphics subsystem generates a 3-D image from 3-D image data stored in display memory portion of video memory and superimposes the 3-D image with texture map data from the off-screen portion of video memory. Texture map data may be continually updated by MPEG decoder 360 on a periodic basis without interfering with the operation of the graphics subsystem. The resultant 3-D image with animated texture maps may provide a more realistic display, particularly for animated objects, such as a human face.

  • Patent number: 5611041
    Abstract: A memory controller, particularly for use in a video controller, is provided which reduces the effect of page misses during memory access. A video port FIFO is provided for buffering data from a video port to a display memory. A CRT FIFO is provided for buffering data from a display memory to a display. If, during a video port FIFO cycle, a page miss is encountered, the video port FIFO cycle is terminated and processing passes to a CRT FIFO CYCLE. If a page miss is encountered during a CRT FIFO cycle, the subsequent video port FIFO cycle will shortened by a number of memory cycles to compensate for the additional memory cycles required by the page miss. Additional data accumulated in the video port FIFO may be transferred to the display memory during a retrace interval. In this manner, memory bandwidth is optimized by removing a non-aligned page miss as the worst case of memory bandwidth utilization.

  • Patent number: 5598352
    Abstract: A multimedia system including an audio/video decoder/decompresser for decoding/decompressing a compressed encoded audio/video data stream to generate video images for display and audio signals for audible reproduction. The multimedia system includes an integrated system and video decoder with an audio/video synchronization circuit for substantially synchronizing the display of video images with audio playback. An audio presentation time stamp (APTS) is detected in the compressed/coded audio data stream in the integrated system and video decoder and stored in a data latch. The compressed/coded audio data stream is fed to an audio decoder which decodes/decompresses the audio data and outputs and audio signal. The audio decoder detects when audio data corresponding to an APTS had been output and sets a corresponding flag. The flag indicates to the integrated system and video decoder that a corresponding audio segment had been decoded/decompressed and output.

  • Patent number: 5595914
    Abstract: Precise and accurate determination of gypsum in soils has been difficult, laborious and time consuming by currently available methods. The present invention solves such problems by: 1) Direct removal of nongypsic sulfate from 2-g soil sample with 25-mL portion of 50-% (v/v) ethanol, thus, eliminating positive errors in gypsum measurement from sulfate analysis while causing essentially no loss in gypsum content of the sample, and 2) stoichiometric conversion of soil gypsum to Na.sub.2 SO.sub.4 and CaCO.sub.3 (s) by two equlibrations of the soil sediment with 25-mL increments of 0.5M Na.sub.2 CO.sub.3 solution plus 30-s sonification. The SO.sub.4 in the supernatent solution is centrifuge separated, analyzed by the standard BaSO.sub.4 gravimetric and turbidimetric methods, and gypsum content is computed from equation [8]:gypsum(g)/soil(kg)=[SO.sub.4 (g) /soil(kg)(172/96.

  • Patent number: 5596420
    Abstract: A multimedia system including an audio/video decoder/decompresser for decoding/decompressing a compressed encoded audio/video data stream to generate video images for display and audio signals for audible reproduction. The multimedia system includes an integrated system and video decoder with an audio/video synchronization circuit for substantially synchronizing the display of video images with audio playback. Latency between Audio and Video decompression/decoding may be adjusted dynamically by internal hardware. Hardware signals indicating the need to skip or repeat a frame or frames of video or audio data are fed to a hardware circuit which may increment or decrement a latency value accordingly. The latency value is thus stepwise incremented or decremented until no further frame skips/repeats occur. The hardware implementation allows for better matching of latency value to audio and video decoder, frees up software for other tasks and reduces software code requirements.

  • Patent number: 5546344
    Abstract: A DRAM interface, particularly for use in a video controller IC is provided with an improved technique for latching data from an extended data output (EDO) DRAM. An inactive column select CASn signal is fed back through the output of the DRAM interface, along with a write enable signal WEn, to emulate delays of such signals within the extended data output DRAM and the DRAm controller. The inactive CASn signal and write enable signal WEn are ANDed together to produce an ENABLE signal for latching data in a transparent latch. The use of the ENABLE signal optimizes the performance of the EDO DRAM and prevents collision of read and write data.
