A distributed switching system is disclosed which includes a plurality of simple-function switching units interconnected by speech path links, each unit having a speech-path switch, a plurality of processing units connected to speech-paths for use in signal and call processing, and an inter-unit bus for the connection between the switching units and the processing units, and functions as a single large switching system as a whole.

A distributed, fault-tolerant, self-repairable, reconfigurable signal processing system with redundant elements comprising signal processors, mass memories and input-output controllers interconnected by redundant busses forming a high reliability system. The input-output controller element has redundant busses for interconnecting multiple fault-tolerant distributed signal processing systems into a network configuration. One signal processor element in a system is initially designated as the exec...

In time division communication systems one conference technique is to have a processor combine those samples going to a particular station forming a conference having as many subcombinations as there are stations. This approach, while allowing individual station gain adjustment, suffers from its dependence upon a large number of logic operations for a given conference. A modification of this technique is disclosed which uses a distributed structure such that the individual station ports, under l...

An indexing system adapted to periodically advance a web of metal through a plating line that first advances gently till it engages a hole in the web, then closes clamping members about the web to grasp the web over a distributed region, and only then moves the web at full speed.

A synchronization system is provided for a tree-type transmission system comprising a central station connected to a plurality of remote stations in an effectively sequential manner, each station including transmitting and receiving means for digital data in a sequence of frames. Each remote station is instructed regularly by the central station of the time delay between the remote station and the central station. The remote station stores the time delay and arranges to advance information trans...

A method and apparatus are presented to facilitate simulation of complex systems on multiple computing devices. Model authors can specify state-related information to be exported for viewing or access by other applications and models. Subsystem models may be written to enable connection with other subsystem models via controlled interfaces, such as by defining state-related information for export and providing for a particular use of data imported from other models to which a subsystem model is ...

In a system and method for the distribution of identities and reputation on a network, identity and reputation information may be distributed among nodes on a network (e.g. nodes on a peer-to-peer network). Embodiments may allow nodes on the network to evaluate other nodes' reputation using the distributed reputation information. Embodiments may allow nodes to iteratively increase confidence in a determined reputation of a node by determining the reputation of nodes that provide reputation infor...

In electronic watch-and-band arrangements the batteries are located in the band portion, separately from the watch movement and display. This permits the arrangement to assume novel configuration and gives it novel disposable features.

A digital multiplexer circuit includes an input transmission line structure receiving input signals, multiplexing blocks having input terminals that are successively coupled together by the input transmission line structure, and an output transmission line that successively couples output terminals of the multiplexing blocks and receives output signals from multiplexing blocks.

Signal propagation time through a transmission gate array or multiplexer is significantly reduced and output signal transition time is halved by detecting non-selection of a section of the multiplexer and activating an output circuit, preferably in the form of a logic gate, to respond to a signal passed through a selected section of the transmission gate array or multiplexer. Specifically, upon non-selection of a section, an appropriate logic-valued signal at a reference voltage is propagated on...
