Title: Switch integrated controller for energizing an external electrical device
Inventor: TODOKORO TAKAYUKI
IPC: H01H43/02
Filed: 1998-10-07
Abstract: A switch integrated controller capable of giving a wide variety of controllers at a reduced cost. The controller has a casing composed of a controller module and a terminal module which are separately formed from each other and detachably connected to each other. The controller module has an entry section for receiving a specific external condition and a signal generating section which generates a trigger signal when the specific condition is met by a predetermined reference. The terminal module includes at least one pair of terminals which are adapted to be connected through wires to the external electrical device and an associated external power source and further includes a relay switch which is connected between the terminals for selectively connecting and disconnecting the electric device to and from the electrical power source in response to the trigger signal. Thus, the terminal module including the relay switch can be made common to different kinds of the controller modules and can be assembled with the controller module into a single unit only at an expense of simple mechanical connection between enclosures of the respective modules and electrical connection between the switch relays and the signal generating section. With this result, a wide variety of controller units of different functions can be fabricated at a reduced cost.

Title: Incremental network routing
Inventor: SOUKUP JIRI
IPC: H04L45/02
Filed: 1999-03-25
Abstract: This invention relates to improvements in the manner in which data is routed through a data network.      A method for determining optimal data routes is defined, specifically suitable for situations when only a few links and/or nodes have changed since the last optimization. In addition to the data organization used in known variations of the Dijkstra procedure, the new method records all nodes whose cost improved during the optimization process. It also suplements the traceback pointer by a tree organization, which permits the traversal of optimum routes in both directions. The method of determining the optimum routes between a source node and all destination nodes comprises: (i) assigning an infinite cost and undefined traceback to nodes whose original path ran through a node or a link which has been disconnected, or through a link whose cost has increased; (ii) starting the expansion process from those nodes F which have final costs and satisfy at least one of the following conditions: (a) there is a link which can transmit data from node F to node I, where I has infinite cost; (b) there is a new link which can transmit data from node F to another node; (c) the cost of one of the links which can transmit data from F to some other node has changed; (iii) the routing table is updated only for the nodes whose costs have improved during the expansion process. In this way a new set of optimum routes from the source node is determined.
