A power converter includes a DC to AC inverter that is connected to a neutral node formed between first and second capacitors connected across two DC supply lines. The inverter is operated to selectively couple the DC supply lines and the neutral node to an output terminal thereby producing an alternating voltage waveform formed by a sequence of output pulses having positive, zero and negative voltage levels. To compensate for a voltage imbalance across the capacitors, an imbalance compensation coefficient is derived from the difference in voltages across the first and second capacitors and from the direction of current between the neutral node and the inverter. The imbalance compensation coefficient is employed to adjust the width of the output pulses so as to charge and discharge the capacitors to correct the imbalance.

A multiple key, multiple tiered network security system, method and apparatus provides at least three levels of security. The first level of security includes physical (MAC) address authentication of a user device being attached to the network, such as a user device being attached to a port of a network access device. The second level includes authentication of the user of the user device, such as user authentication in accordance with the IEEE 802.1x standard. The third level includes dynamic assignment of a user policy to the port based on the identity of the user, wherein the user policy is used to selectively control access to the port. The user policy may identify or include an access control list (ACL) or MAC address filter. Also, the user policy is not dynamically assigned if insufficient system resources are available to do so. Failure to pass a lower security level results in a denial of access to subsequent levels of authentication.

A data flow egress scheduler and shaper provides multiple levels of scheduling for data packets exiting communications devices. A classifier separates data from multiple sources by data flow and by priority within a data flow. An output controller requests a data packet for transmission and the scheduler selects a next available highest priority packet from a next in sequence data flow or from a management data queue. The shaper can control the rates of classes of service to be scheduled by the device. The scheduler typically comprises three levels of scheduling. Large numbers of output ports can be implemented in a single device by a virtual scheduler that services each data flow, output port and data source as a shared component, maintain context for groups of schedulers and data flows.

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.

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.

A memory uses multiple threshold levels in a memory cell that are not a power of two, and further uses a cell mapping technique wherein the read mapping is only a partial function The domain of read states for a single three-level memory cell, for example, has three states, but only two of them can be uniquely mapped to a bit. The domain of read states for two three-level memory cell, for example, has nine states, but only eight of them can be uniquely mapped to three bits. Although the read mapping is only partial, the voltage margin for the three-level memory cells is larger that the voltage margin available in the commonly used four-level memory cells. This increased voltage margin facilitates memory cell threshold voltage sensing, thereby increasing the reliability of the memory. Memory reliability may be further improved by increasing the voltage margin between the memory cell 0 state and the 1 state relative to the voltage margin between the 1 state and the 2 state, which more effectively accommodates charge loss from the 0 state through electron leakage. Asymmetrical read and program mapping may also be used to improve read reliability in the presence of ground noise or VCC noise.

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.
