Abstract: The graphics applications of a 2-D graphics computer system provide each object to be rendered on a 2-D raster display with a pair of rendering reference coordinates (x and y), and a relative depth value (z). Additionally, the computer system is provided with a library of predetermined 2-D images and sounds, and a number of graphics toolkit routines. As the user "moves", the graphics toolkit routines render selected ones of the predetermined images based on x/z and y/z values of recomputed x and y rendering coordinates and the relative depth value z of the objects, and actuate the sounds if applicable based on their predetermined manners of rendering. As a result, the objects that are further away from the user will move slower than the objects that are closer to the user, thereby introducing the effect of parallax and added realism to the 2-D graphics computer system at a substantially lower cost.

Abstract: CODECs and various other types of communication devices requiring timing information to enable them to transmit and receive digital information at the proper time. In the case of multiple CODECs (e.g., 101 ... 104) on a single integrated circuit, this has typically required devoting terminals to provide separate transmit and receive frame synchronization pulses (e.g., FST₀ ... FST₃; FSR₀ ... FSR₃) for each CODEC. Alternatively, a microprocessor interface may be included so that internal registers can be loaded with transmit and receive timing information. However, that approach limits timing flexibility. In the present invention, a "frame synchronization separation pulse" (FSEP) is provided to an integrated circuit (e.g., 301) to obtain the separation in time between transmit and receive synchronization pulses. In this manner, the number of integrated circuit terminals required for synchronization may be reduced.

Abstract: In a manufacturing process using multivariate analysis for statistical process control, data representing a plurality of process and/or product variables is collected during operation of the process. A surrogate variable, representing the overall state of the process is evaluated. The surrogate variable is a function of a plurality of intermediate variables, which in turn are a function of the process and/or product variables. When the value of the surrogate variable is outside of a predetermined limit, the contributions to the surrogate variable by the intermediate variables are calculated. The intermediate variable with the largest contribution is identified and the contributions to the identified intermediate variable by the process variables is calculated. The process variables with the largest contribution to the identified intermediate variable are identified, and used to diagnose and correct the problem with the process.

Abstract: Apparatus and a method for formatting executable codes and data, defining interactive applications, with video and audio program material, for reliable and convenient access includes compressing (18, 21) audio and video programs according to a protocol such as MPEG. The compressed audio and video (A/V) programs are segmented (19, 22) into transport packets and identified by first and second service identifiers SCID Ai  and SCID Vi . Interactive application programs associated with A/V programs are compiled (10) into functional modules and condensed. Further modules designated "Signal modules", are generated to condition respective receivers to suspend or resume execution of an interactive application. Signal modules are multiplexed in the packet stream to appropriately reprogram respective receivers on the occurrence of such changes in received signal components. A module may be executable software or data. A module includes code/data and a header. The code/data portion of each module has cyclic redundancy coding (CRC) check bits appended to the module. Respective modules are segmented (14) into transport packets. The transport packets are formed into transmission units comprising an integer number of code/data transport packets and a header transport packet. Video packets, audio packets and module packets are subsequently time division multiplexed (16) for transmission.

Abstract: A method for ultrasonically welding two plastic parts together. One part (30) has a weld joint feature (23) that is covered with a metal layer (27), and the other plastic part (25) has a complimentary weld joint feature. The two parts are joined together by ultrasonically welding the two weld joint features to each other. A force (40) is applied to the first and second plastic parts prior to the step of welding. The force is substantially in excess of that required to cause the two weld joint features to contact each other. This method creates an ultrasonic welded metallized plastic assembly. Each part of the assembly has a weld joint feature, at least one of which was covered with a metal layer prior to welding. Portions of the each of the two weld joint features are deformed to form a plastic weld joint through the metal coating.

Abstract: In a diversity communication system, arrays of antennas and groups of receive units are provided so that the groups correspond respectively to the antenna arrays. The receive units of each group respectively process incoming signals from the antennas of the corresponding array. Associated respectively with the antenna arrays are diversity branches each comprising multiple complex multipliers for respectively multiplying the processed incoming signals by weight coefficients, and multiple correlators for determining correlations between the processed incoming signals and a decision signal and deriving therefrom the weight coefficients of the complex multipliers. A predetermined amount of delay is introduced to each of the processed incoming signals so that each delayed signal and the decision signal are time-coincident at the inputs of each complex multiplier. The output signals of the complex multipliers are summed and fed to an adaptive matched filter for converging delay-dispersed components of the sum signal and maximal-ratio combining the components according to the decision signal to produce an output signal of the diversity branch. The outputs of the diversity branches are combined and applied to a decision feedback equalizer where it is equalized and the decision signal is produced for the correlators and adaptive matched filter of each diversity branch.

Abstract: For making in a parallel computer system an interconnection network transfer data sequences, each composed of consecutive packets, from input ports (17) to a destination port indicated among output ports (19) by a routing address specified by a leading packet of each data sequence, control registers (31) hold the routing address of a privileged sequence determined by arbiters (39) in response to such addresses held in the control registers and stored in control buffers (33). Data of the consecutive packets of the privileged sequence are simultaneously stored in and produced from data buffers (37). Controlled by the arbiters, input selectors (41, 43) select the data for delivery to the destination port through output buffers (55) and output selectors (57) controlled by a selector operating arrangement (59-63). When the data of the consecutive packets are not yet wholly stored in the data buffers, the input selectors select only those already stored in the data buffers and then select the data of remaining ones of the consecutive packets as soon as they reach the data buffers.

Abstract: In an internal combustion engine in which the valve operating characteristic for intake valves can be switched, and the air-fuel ratio can be switched between a relatively lean level and a relatively rich level, the air-fuel ratio is switched in accordance with a change in engine operating condition, and the valve operating characteristic for intake valves is switched substantially synchronously with the switching of the air-fuel ratio, between an operating condition-suited valve operating characteristic suited to an engine operating condition before the switching of the air-fuel ratio and an operating condition-suited valve operating characteristic suited to an engine operating condition after the switching of the air-fuel ratio, via an operating condition-unsuited valve operating characteristic which is not suited to the engine operating condition after the switching of the air-fuel ratio, so as to provide an engine output which is a middle value between engine outputs before and after the switching of the air-fuel ratio. Thus, it is possible to moderate the torque shock produced upon the switching of the air-fuel ratio, while inhibiting the generation of NOx.

Abstract: A method and apparatus for storing scaleable font data (430) in a compact form and retrieving it in one of several usable forms common in digital typography. The retrieval process can be influenced by parameters to produce not only the original typeface designs (514) that were compressed, but also variations on those typeface designs (514). Variations produced in this manner are related typeface designs (514) which therefore effectively add new fonts to the family originally stored. Individual character pixelmaps (360) and scaleable character outlines (212) are two of the forms which can be retrieved from the compressed font data (430). The storage and retrieval methods are designed so that the time needed to produce a single character pixelmap (360) from the internal form is less than that required for producing the same pixelmap from an uncompressed hinted outline font (470) stored in an industry-standard format.

Abstract: The present invention discloses a method of and apparatus for regulating the power of signals transmitted by transmitting units, such as mobiles or base stations, that are using the same channel in a cellular radio system. An iterative process is disclosed in which the demands of synchrony and coordination among the transmitting units are relaxed. The power of the signals converges at a geometric rate to optimal transmission powers, where the optimal transmission powers are defined as the minimum powers required to maintain the ratio of carrier power to co-channel interference power at least as large as some pre-fixed target value obtained from quality of service considerations. As a result of relaxing the demands of synchrony and coordination, expensive clock or timing mechanisms are not required, thereby reducing the costs of power control.
