  • Publication number: 20020075864
    Abstract: A signal router routes N inputs to M outputs. All inputs signals are ultimately applied to a data buss by spreading across multiple buss lines and time multiplexing. The data are read from the buss and written in identical images to K random access memories. The memories are addressed and read according to a different schedule for each of K output signals that are ultimately demultiplexed to M outputs. As each RAM image is read, another RAM image is written and vice versa. Since each RAM image contains the same data, the generation of signals from each RAM to supply each of the respective K output signals can be done at a rate that is substantially more independent of the input, buss, or RAM write operations than prior art techniques permit.

  • Patent number: 6380721
    Abstract: The performance of the main regulatory transistor of an on-chip voltage regulator circuit is enhanced when the main transistor is appropriately biased during start up. In an example embodiment, a voltage regulator circuit includes a thin gate oxide transistor as the main regulatory transistor and an operational amplifier that is referenced to a midlevel operating voltage. During start-up, the potential voltage difference is large enough to necessitate the disconnection of the main transistor from the operational amplifier. A voltage divider ladder circuit is used to maintain the gate voltage of the main transistor at the midlevel voltage while a smaller thick gate oxide transistor is used to maintain loop stability and to withstand voltage transients.

  • Publication number: 20020044570
    Abstract: Cable TV providers have an infrastructure which is well suited for providing additional services such as telephone and data connections to their subscribers. Techniques are disclosed for improving the error detection, masking, and avoidance capabilities of such a system. Because the system can distinguish telephony from data traffic, alternate error masking techniques can be employed for each type of traffic. An erroneous telephony packet, for example, can be replaced by silence, because the ear is relatively insensitive to short voids. Additionally, the links to the data or telephony provider can be maintained by the cable provider during interim noise periods. Because the network is structured as a multiple access network, and the likelihood of simultaneous upstream messages from all subscribers is low, error monitoring can be implemented on underutilized equipment to effect error avoidance, both as a preventive measure as well as a corrective measure.

  • Patent number: 6337893
    Abstract: A gray-code counter system (AP1) for a RAM-based FIFO comprises a read pointer (10), a write pointer (20), and a detector (30). The read pointer includes a gray-code decoder (11), a binary incrementer (12), a gray-code encoder (13), and a register (14) that holds the pointer count). The binary incrementer increments by 1 except when the input is 0110 (decimal 6) or 1110 (decimal 14); in these cases, it increments by 3. The result is a 4-bit modulo-12 gray-code sequence with the twelve allowed gray-code values being distributed among the sixteen possible 4-bit gray code values with translational and reflective bilateral symmetry. The write pointer is similar. Because of the translational symmetry, detectors that work with counters with modulo numbers that are power of two work with the corresponding non-power-of-two counter to provide “full” and “empty” indications.

  • Publication number: 20010052851
    Abstract: A security system incorporates a reasoning system and security rules and processes that are designed to be as unobtrusive as the situation permits. Two independent aspects of the system facilitate the enforcement of rules and processes in an unobtrusive manner. First, transponders that can be triggered and sensed from a distance are preferably used to identify both items and individuals. These remotely sensed identifiers are processed by the reasoning system to determine whether each identified item is authorized, or likely to be authorized, to be removed from, or brought into, a secured location by the identified individual. Second, the system continually modifies and optimizes its rules and processes based on assessments of security events. An initial set of rules is created for the security system that, generally, prohibit the removal of secured items from the secured location, except that certain individuals are authorized to remove specified items from the secured location.

  • Patent number: 6317522
    Abstract: This invention relates to a system and method for reducing blocking artifacts introduced by current compression algorithms that compress images as independent blocks of pixels. Preferably, the methods of the invention include determining block-to-block differences in edge pixels or in overall intensities between adjacent pixel blocks, selecting pixel blocks for post-processing that appear to be in relatively featureless regions of the image, interpolating the block-to-block edge differences into a error correction matrix, and then subtracting the error correction matrix from the original pixel block. These methods are preferably implemented in special software routines that execute on micro-processor based systems or on digital signal processor based systems optimized for image decoding.
