Error coding in asynchronous transfer mode, internet and satellites

The transmission of ATM, Internet, and satellite communications is unified through international standardized protocol embedment. Global and Local performance optimization are achieved through the combination of combinatorial, dynamic, and probabilistic programming. A simultaneous domino effect of bandwidth conservation, efficiency enhancement, reliability improvement, traffic congestion prevention, delay minimization, and speed multiplication are realized for any digital communication system, particular in Internet. With three levels of error coding in ATM cells, the loss cell recovery and bit integrity are preserved. From its mathematical roots, new combinatorial sets are systematically generated, and applications of the sets are identified. Among the applications, optimal sequences can be produced for multi-user and multi-function communication system designs. Optimality is in terms of maximum possible number of sequences with given sequence length and sequence characteristics. The results are unique and theoretically proven. By serial and parallel concatenation of error codecs, reliability of multimedia transmission can be satisfied to any desirable level. As a part of the unified transmission scheme, the acquisition and synchronization method of cascading sequences exhibits significant improvement in correlation properties and detection probabilities. A method of using block designs is demonstrated to derive, to generate, and to construct low-density parity check block codes and threshold decodable convolutional codes. An efficiency evaluation method is formulated for the combination operation of ATM, Internet, and satellites.

Method and apparatus to manage network client logon scripts using a graphical management and administration tool

A GUI (Graphical User Interface) Manager is used by a network administrator to fill-in predefined templates. The administrator does not need to compile, debug or write a single line of scripting code. The GUI manager has a “select the box” and “point and click” and “fill-in the blank” approach for selecting computer settings. The predefined configuration and/or template(s) are used by a logon script program on a client system to manage the configuration of resources on at least one client. There are three levels of resources that can be managed. The first type of resource is an operating system. The second type of resource is an application resource. And the third type of resource is to redirect a resource on the client to a resource on a network such as a drive letter mapping. Resources include configurations from the group of configuration settings consisting of drive mappings, shell folders, printer deployment, proxy server access, application paths, service packs, anti-virus updates, policies and automatic mail profile creation. In another embodiment, validation logic is used on the clients' system during the execution of an application program that takes the template and applies the defined configuration settings in the template to the clients' system so as to automatically configure at least one configuration setting for a user if the combination of one or more predefined conditions for a selected group, a selected operating system and a selected connection method are met. In still another embodiment, an interpretive engine is used on the client's system to permit the administration of client resources with a template while also allowing network administrators to build their own custom logon scripts.

Self-biasing CMOS PECL receiver with wide common-mode range and multi-level-transmit to binary decoder

A pseudo-emitter-coupled-logic (PECL) receiver has a wide common-mode range. Two current-mirror CMOS differential amplifiers are used. One amplifier has n-channel differential transistors and a p-channel current mirror, while the second amplifier has p-channel differential transistors and an n-channel current mirror. When the input voltages approach power or ground, one type of differential transistor continues to operate even when the other type shuts off. The outputs of the two amplifiers are connected together and each amplifier receives the same differential input signals. The tail-current transistor is self-biased using the current-mirror's gate-bias. This self biasing of each amplifier eliminates the need for an additional voltage reference and allows each amplifier to adjust its biasing over a wide input-voltage range. Thus the common-mode input range is extended using self biasing and complementary amplifiers. The complementary self-biased comparators can be used for receiving binary or multi-level-transition (MLT) inputs by selecting different voltage references for threshold comparison. Using the same reference on both differential inputs eliminates a second reference for multi-level inputs having three levels. Thus binary and MLT inputs can be detected and decoded by the same decoder.

Three-phase four-wire three-level photovoltaic grid-connected connection inverter and control method thereof

The invention relates to a three-phase four-wire three-level photovoltaic grid-connected inverter and a control method thereof. In the inverter, voltage input from a solar panel is filtered by a filter capacitor; the input voltage is boosted by a boosting circuit to form direct-current bus voltage serving as input voltage of a post inversion circuit; the bus voltage is inverted by a three-phase four-wire inversion circuit to form three-phase voltage; after being filtered by a filtering circuit, the three-phase voltage is output to a power grid; a controller detects the voltage and output current of the solar panel, the three-phase voltage of the power grid and three-phase current output by the three-phase four-wire inversion circuit; a boosting converter and an inversion controller in thecontroller 101 respectively generate driving pulses of the boosting circuit and the three-phase four-wire inversion circuit to control the operation of the integral inverter. A three-phase four-wire power supply system is formed by the addition of a neutral line, so the inverter can be connected with symmetrically-balanced three-phase loads, and also can be connected with single-phase loads. The application field of the photovoltaic inverter is broadened while the safety of the power supply system is improved.
