Abstract: There are methods and apparatus, including computer program products, for managing hierarchical reference data. There is a Web page for access by a user, where the Web page includes (i) data representing a hierarchy and (ii) rules defining modifications that are permitted to be made to data. The user is enabled to make a real-time modification to the data based on the rules.

Abstract: A printed circuit board includes an edge connector operable to be coupled to an expansion bus. An integrated circuit is mounted on the printed circuit board and is coupled to the edge connector. The integrated circuit is operable to snoop memory operations on the expansion bus and cause selected memory data to be stored in a memory on the printed circuit board. A first power conductor extends across a first portion of the printed circuit board and is coupled to the integrated circuit. A second power conductor extends across a second portion of the printed circuit board and is also coupled to the integrated circuit. The circuit board also includes a decoupling unit connected between the first power conductor and the second power conductor. The decoupling unit causes disconnect of the first power conductor from the second power conductor during times in which voltage within the first power conductor is less than voltage within the second power conductor.

Abstract: A communication system is presented whereby sequences of video screens sent from a host CPU to a video controller can be stored and subsequently retrieved by a terminal located remote from the host CPU. Detection logic, controller memory, processor and a communication unit are compiled as a system configured upon a PCB. The PCB is configured to maintain certain vital functions even if power supplied from an expansion bus ceases. The PCB may employ a battery which maintains processor and controller memory activities and communication therebetween for a period of time sufficient to sustain video screen information stored within the controller memory. Thus, decoupling circuitry is present which prevents drain upon the battery if the communication unit is not being used. The decoupling unit separates power and signal conductors between portions of the printed circuit board.
