Abstract: Energy consumption meters are associated with owners who hold accounts with a power supplier. The meters are assigned meter identifiers and identifiers for their respective owners. Such a meter may be a parent meter having associated submeters. In response to being plugged into a power source from the power supplier, such a meter reports its owner identifier and meter identifier to the supplier. Also, in response to being plugged into a power source supplied by one of the parent meters, a meter communicates with the parent meter. This establishes that the parent meter is associated with the submeter. The submeter measures energy delivered reports this to the power supplier. Also, the indicated association of the submeter to the parent meter is reported to the power supplier. The receipt of this information enables the power supplier to debit and credit owner accounts in a manner permitting temporary associations of meters.

Abstract: A first device is operable to communicate on an bus according to a first protocol. A bridge is also operable to communicate on the bus according to the first protocol. A second device is coupled to the bus via the bridge and operable to communicate according to a second protocol. The bridge has a memory for holding data received from the second device and is operable to translate from the second to the first protocol. The second device sends write data responsive to receiving a ready signal from the bridge, and includes memory for holding the write data that the second device has sent, but for which completion has not been signaled. The second device re-sends the write data from the memory responsive to receiving a non-completion signal via the bridge, and releases the memory for the data responsive to receiving a completion signal via the bridge.

The profile includes a set of voice mail conditions and a corresponding set of conditional actions. Each condition specifies at least one characteristic of an incoming call or system access request. The voice mail system processes a system access request or incoming call by determining whether at least one of the voice mail conditions is satisfied and, if so, responding to the system access request or incoming call according to the corresponding conditional action.

Abstract: A method and system for managing the transfer of data in parallel through multiple sockets. The present invention facilitates the use of multiple sockets and avoid monopolization of a socket by releasing the socket as soon as data from a client request has been sent to a server application. The present invention also includes a novel socket assignment technique that assigns only available sockets. This novel socket assignment technique avoids bottlenecking and delays due to socket contention and increases efficiency. The socket assignment technique of the present invention can assign sockets using a round robin technique, which assigns a server application to a first available socket, a random technique, which assigns a server application randomly to an available socket, or a user-defined technique, which assigns a thread to an available socket as determined by a user.

Abstract: Hardware errors are stored in an error buffer for processing by one or more system partitions within a computer system. When errors are first placed in the buffer, an Already Reported Flag (ARF) is initialized to indicate that the error has not yet been reported to any of the system partitions. When one of the system partitions receives the corresponding error information by running a diagnostics routine, the ARF is set indicating that the error has been reported to at least one system partition. The system partition, in turn, uses the ARF information to determine how to handle the corresponding error. In an environment using a remote hardware service provider, the ARF determines whether to transmit the error information to the service provider. In environments without remote service providers, the ARF information is used to highlight newly reported errors to the user.

Abstract: A universal credit card system utilizes a portable card access device which stores information associated with multiple bank card accounts, electronically authenticates a user of the bank card accounts, allows the user to select a particular one of the bank card accounts for usage, and then magnetically encodes the selected bank card account information on a separate card substrate (a “universal” credit card) and releasing the card for use. Bank card account information can be stored by inserting an existing bank card into the access device and reading the existing bank card, by manually entering the information using a keypad, or by downloading the information from a computer directly to the card access device. Authentication may be performed using an optical fingerprint scanner. After use, the universal credit card is re-inserted into the card access device and the previously selected bank card account information is erased.

Abstract: A visual indication on a cursor control device is triggered when the cursor is within a designated region on said display screen. Usually the user activated cursor control device is a computer control mouse, but the invention may operate effectively with joy sticks and trackballs. An effective implementation provides a light on the control mouse and the target region on the display screen for the cursor is an icon. The light on the mouse may be a variable light. It may be varied dependent upon the type of region on the screen which is the target region, e.g. one type of light if the target region is a display window and another type of light if the target region is an icon. The variation in the light may be light intensity or color.

Abstract: A method for a user interface includes selecting information from a current location and placing the information in a queue for later placement at a destination, and then selecting a destination and placing the information at the destination. Responsive to the placing of the information in the queue, and until the placing of the information at the destination, the information is displayed in the current location and an appearance of a user display pointer shows that the queue has an entry. The queue is capable of holding second information concurrent with the first information.

Abstract: Tracking the success or failure of and the quality of communications between requesting client station computers and servers, particularly servers for accessing resource locations for the present complex and circuitous environment. Conventional browsers are provided for requesting the transmission of data components from one of said resource locations to one of said client stations. There are also implementations, associated with the client station requesting the transmission of data components, for tracking characteristics of said transmission in combination with sending said tracked characteristics to at least one network server on the path of said transmission. In the complex World Wide Web (Web) environment, while the resource location server does not know where its thousand of “hits” are coming from, each requesting client station of those thousands does know the Uniform Resource Locator (URL) or address of the server.

Abstract: The present invention is embodied in a system and method for creating markers on scroll bars of a graphical user interface. Basically, the present invention allows users to reference locations of interest within a document using scroll bars of a user interface by creating graphical halt and pause points on the scroll bar at the locations of interest. In general, the present invention includes a user interface with a digital document of an application being used by a user. The application has at least a vertical scroll bar for moving from one location to another within the digital document. The scroll bar includes a scroll box, stub points and end points. The stub points represent reference points within the digital document that are predefined by the user. The stub points either stop or pause the movement of the scroll box as it moves along the scroll bar. The end points represent the top and bottom portion of the digital document.

Abstract: A file system maintains information about files in data areas called dinodes. Dinodes are grouped into dinode pages wherein each dinode page includes information about one or more dinodes. Each dinode may use extended attribute data. Each dinode page having at least one dinode that uses extended attribute data has a corresponding dinodex page. The dinodex page includes extended attribute information about any of the dinodes in the dinode page that use extended attribute information. The page is divided into areas, each area corresponding to a different dinode. A lock is established for each dinode page so that any dinode adding or deleting its extended attribute address obtains the lock before proceeding to maintain cooperation between the dinodes. In this manner multiple extended attribute areas are prevented from corresponding with a particular dinode page and unused extended attribute pages are removed without unduly impacting system performance.

Abstract: A modified client application within a network for use in accessing and displaying cached files. The modified client application has access to a client cache in which a copy of files downloaded from the network server is stored. When a particular file is requested, logic components within the client application determine if the requested file is resident in the client cache. If the requested file is resident in the client cache, the file is displayed within the graphical user interface (GUI) of the requesting application along with an indicator by which the user is notified that the displayed file is a cached file. Different indicator types are possible, including a cache message button which is displayed within the application GUI, and a color coded scheme which causes the file or fileile border to be displayed in a different color whenever the displayed file is cached.

Abstract: A processor having improved branch prediction accuracy includes at least one execution unit that executes sequential instructions, a condition register, and a branch prediction circuit that predicts a condition register-dependent branch instruction by reference to a potentially stale condition register value to produce a speculative instruction fetch address. In a preferred embodiment, the processor includes branch execution circuitry that subsequently determines if the speculative instruction fetch address is correct by reference to a non-stale value of the condition register.

Abstract: A method for testing a computer bus using a bridge chip having a freeze-on-error option that enables a computer system's central processing unit (CPU) to recover and continue processing even when the computer bus is not functional. The testing method of the present invention remains transparent to a user and can be accomplished while performing standard diagnostics tests. In general, the present invention injects an input/output (I/O) error into a specific bus slot of the computer bus to test the functionality (such as the error recovery capability) of the bus. The present invention then recovers from the failure condition without having the computer system shutdown or stop working and without having to restart the computer system. More specifically, the method for testing a computer bus according to the present invention includes enabling the freeze-on-error option on the bridge chip, injecting an error into the specified computer bus slot and recovering from the injected error.

Abstract: A system and method for releasing storage space at the beginning of a byte stream while maintaining sequential byte stream semantics is provided. A ghost offset is initialized when a file is instantiated or opened. When information is deleted at the beginning of the sequential byte stream, the ghost offset is incremented in the amount of the number of bytes being deleted. The ghost offset continues to increment while the file is opened and information is being deleted at the beginning of the data stream. The virtual offset is the ghost offset added to the real offset of a particular entry in the data stream which maintains sequential byte stream semantics. When the file is closed, storage space is released in the amount of the ghost offset. Applications are provided with virtual offsets corresponding to data locations which are converted to real offsets for accessing data in the data stream.
