Abstract: The present invention provides modular trays having cutout features that are configured to engage with a mounting feature of one or more removable rails. The removable rails may be removeably secured to a tray body in a plurality of positions to allow a user to install or uninstall rails to support different sized fiber optic modules. For example, a tray may support a twenty-four optical fiber module, two twelve optical fiber modules, or three eight optical fiber modules. Fiber optic enclosures housing the trays can be affixed to the outside of a fiber optic enclosure and allow for easy stacking and unstacking.

Abstract: An indicator system for an electronic miniature circuit breaker that has tripped and therefore has no power to provide its own trip indication comprises a breaker in a tripping state and an adjacent breaker in a nontripping state, both with aligned indicator light tubes and data transmission lines or light pipes. The tripped, or tripping, breaker sends a Notice of Trip Data signal before its contacts open and its power goes out, or does so on reserve power. A neighboring breaker's transceiver receives the Notice of Trip Data signal, encodes it, and then repeats it back via an LED and indicator light tube to the tripped breaker. The trip occurrence has opened a shutter on the tripped breaker which allows it to display the repeated Notice of Trip Data signal as a visible light indication through an indicator window in its top wall.

Abstract: With the increasing usage of mobile devices for communication, the need for wireless base-stations deployed in strategic locations is becoming increasingly important. The increased bandwidths being transmitted between the base-station and the mobile device has mandated that enhanced transmission formats and techniques be deployed, and, in order to operate correctly, these techniques require a tight synchronization in both time/phase, and in frequency, between the various base-stations serving a general area. Due to the need to establish the geographic location of the mobile device with a high degree of accuracy, it is also necessary to establish the location of the serving base-stations with a high degree of accuracy.

Abstract: A communicating circuit breaker architecture with automatic load center position identification links circuit breakers having electronics for reporting a self-status signal including operating data and a position identifier. Each breaker has light pipes with optical ports at its sides for communicating with its neighbors and preferably a mechanically operated optical shunt providing an optical path through the breaker in the event of a trip. Each breaker has optical data transceivers for the light pipes which transmit self-status information through the light pipes and receive and repeat neighboring breaker status signals to its neighbors. The breakers form a network via their aligned optical ports reporting to an aggregator device in a known position of the Load Center which transmits breaker status reports outside the load center. Each breaker has a logic unit for determining its position in the load center based on the received position of a neighboring device.

Abstract: A system and associated method for monitoring and reporting productivity in an enterprise environment. The enterprise environment has a server, a database, a client program and a web interface. The database stores transaction data and administration data. The transaction data stores records of time spent by an end user to perform a certain volume of work for a transaction. The administration data configures operations of the client program per transaction. The client program records a time log and provides an interface to upload a volume log of the transaction. The end user or an administrative user manages content of the database via web interface. The server processes a respective request for recording transaction time and volume log and subsequently generates a productivity report including efficiency, availability, and utilization values based on the transaction data in the database.
