  • Patent number: 6674402
    Abstract: A Global Positioning System carries out Doppler correction of a C/A code sequence after a frequency conversion, and calculates a pseudo range by performing correlation calculation between the C/A code, which is obtained by summing up the C/A code sequence beginning from a polarity inversion boundary determined at a correlation peak detecting step ST10, and a C/A code generated in a GPS terminal. When a received electric field detected by a received electric field intensity detector 11 is good, the current position is determined from the pseudo range and the navigation data extracted by the GPS terminal itself, whereas when the received electric field is poor, the current position is determined from the pseudo range and the navigation data sent from an external apparatus.

  • Patent number: 6674411
    Abstract: An antenna arrangement comprises a patch conductor (102) supported substantially parallel to a ground plane (104) and a feed conductor (106) connected to the patch conductor. Such an arrangement is similar to a conventional Planar Inverted-F Antenna (PIFA), but lacks the additional grounding conductor connected between the patch conductor and the ground plane in known PIFAs. Elimination off this grounding conductor enables matching to be performed by external circuitry, thereby enabling a better match to be achieved and enabling similar performance to conventional PIFA antennas to be achieved from a reduced volume. These advantages are particularly apparent for dual-band (or multi-band) operation, where the use of a dual-band matching circuit allows a much smaller end less complex antenna to be used.

  • Patent number: 6674417
    Abstract: A driving method for driving a plasma display unit of a plasma display panel. The plasma display unit includes two electrodes, and the plasma display unit is filled with ionized gas. A driving circuit drives the ionized gas back and forth between the two electrodes to cause the plasma display panel to emit light. The driving circuit includes a rating source receiver and an energy-storing current source whereby the rating source receiver is able to receive and supply a rating current. The driving method first involves the rating source receiver charging. A first electric potential difference thus occurs between the two electrodes of the plasma display unit to allow the ionized gas within the plasma display unit to discharge. While the ionized gas is discharging, the plasma display unit is supplied with a compensation current to prevent an electric potential difference drop.

  • Patent number: 6674422
    Abstract: A data line driving circuit drives data lines of an electro-optical panel, which occupies a small area and can drive the data lines with low power consumption. When the digit of the most significant bit is “0”, all of the &ggr;-correction switches are in an on-state. Thus, the &ggr;-correction is not performed. Conversely, when the digit of the most significant bit is “0”, the &ggr;-correction switches are put into an on-state according to the data value represented by low order bits. Thus, the &ggr;-correction is performed. That is, whether or not the &ggr;-correction is performed can be determined according to which of the white side and the black side the gray scale level to be displayed is on. Furthermore, irrespective of whether or not the &ggr;-correction is performed, DAC capacitances are used for both the cases that the &ggr;-correction is performed, and that &ggr;-correction is not performed. Thus, the size of the circuit can be reduced.

  • Patent number: 6674426
    Abstract: A method and system designed to augment, rather than replace, the work habits of its users. These work habits include practices such as drawing on Post-it™ notes using a symbolic language. The system observes and understands the language used on the Post-it notes and the system assigns meaning simultaneously to objects in both the physical and virtual worlds. Since the data is preserved in physical form, the physical documents serve as a back-up in the case of electronic system failure. With the present invention users can rollout a primary paper document such as a map, register it, and place secondary physical documents on the map. The secondary physical documents can be moved from one place to another on the primary document. Once an object is augmented, users can modify the meaning represented by it, ask questions about that representation, view it in virtual reality, or give directions to it, all with speech and gestures.

  • Patent number: 6674435
    Abstract: A printer forms an approximate of a Bezier curve as a sequence of line segments. Two parametric equations, X(t) and Y(t), are employed. Two methods can be used to evaluate the parametric equations. Both use fixed point integer arithmetic to directly calculate points along the curve which are the values of the X(t) and Y(t) equations. The first method sets the number of steps of the parametric variable are equal to an integral power of 2. This gives a predictable execution time and uses line segments to connect the points as a piecewise straight line approximation to the curve. The number of steps is set as the next higher power of 2 than an estimated length of the curve. The second method allows Y(t), the scan line variable, to change only in predetermined integer steps. The value of X(t) is evaluated for each t corresponding to the integer step in Y(t). This second method has a natural advantage, if a closed path is being decomposed as a run array rather than a collection of trapezoids.

  • Patent number: 6674437
    Abstract: A system and method facilitating the production, processing, and Internet distribution of 3D animated movies including 3D multipath movies. A key reduction algorithm reduces the keyframes associated with the 3D movie to facilitate the streaming of the data over the Internet. An animation optimization and texture optimization algorithm allows the system to get statistical information of the portions of the 3D object which are invisible (outside the view frame), and whose animation and texture data may thus be safely removed. If the 3D object is within the view frame, the optimization algorithm gathers information about the distance and size of the 3D object and its associated texture data within the frame. The system and method further allows creation of various versions of the 3D object from a single production process. The various versions are tagged with an identifier identifying the target platforms and media platforms in which they are suitable for display.

  • Patent number: 6674441
    Abstract: A method and apparatus for improving performance of an AGP device is provided. In one embodiment of the invention, a second-level cache is provided for a TLB, and part of the data or part of the address that is not otherwise used for determining a TLB entry is divided by a prime number to determine which TLB entry to allocate. One embodiment of the invention provides the ability to load multiple cache lines during a single memory access without incurring additional transfer, storage, or management complexities. The full number of bits of each memory access may be used to load cache lines. One embodiment of the invention loads multiple cache lines for translations of consecutive ranges of addresses. Since the translations included in the multiple cache lines cover consecutive ranges of addresses, the relationship between the multiple cache lines loaded for a single memory access is understood, and additional complexity for cache management is avoided.

  • Patent number: 6674446
    Abstract: A display device (506) is driven in a number of sub-fields. Each of the sub-fields is for outputting a respective illumination level by the display device. In each sub-field, a pixel of the displayed image may emit an amount of light corresponding to the particular sub-field, depending on whether it is switched on or not. A required intensity level of the pixel is realized by selecting an appropriate combination of sub-fields in which the pixel is switched on. A selection is made from the possible intensity levels that can be generated by all possible combinations of sub-fields. This selection contains those intensity levels that can be generated by sub-fields that are temporally close together, thus causing that the light of a pixel is emitted during a relatively short period. The image display unit (300) has a look-up table (306) for storing the combinations of sub-fields for the respective selected intensity levels.
