A fiber optic mode conditioner for obtaining an equilibrium light distribution in a multimode fiber optic link under test. Light is supplied to the link through a gap between two successive fiber optic segments, followed by a high-curvature region created by wrapping the second fiber optic segment around a mandrel. The gap functions as a mode filter, stripping off all but the lowest modes, while the curved region acts as a mode scrambler redistributing the light energy into the intermediate mode...

To allow a telop image to be displayed appropriately even when color information and transparency information for the telop image are transmitted over a network, the present invention provides a telop image sending/receiving system comprising a telop image sending apparatus and a telop image receiving apparatus in which the telop image sending apparatus has an OA fill signal input section for inputting color information for a telop image, an OA key signal input section for inputting transparency...

A method and apparatus for managing contention among users for access to serialized resources in a system cluster containing multiple systems. Each user has an assigned need that is independent of contention of the user for a resource and may be either a holder or a waiter for a resource it is seeking to access. A local system stores local cluster data indicating a grouping of the resources into local clusters on the basis of contention on the local system and indicating for each local cluster t...

A method for managing the suspension and resumption of threads on an individual basis in an information handling system having an operating system (OS) kernel and a user process having multiple threads of execution. An originating thread issues a pthread_kill( ) service request to the OS kernel to send a specified signal (thread-stop or thread-continue) to a specified target thread within the same process to suspend or resume execution of the target thread. More particularly, in response to a re...

An (18, 9) error correction code that is simultaneously double error correcting and triple error detecting is disclosed. The code is defined by the following parity check matrix:.beta..times..times..times..beta..times..times..beta..times..times- ..beta..times..times..times..beta..times..times..beta..times..times..beta.- .times..times..beta..times..times..beta..times..times..beta..times..times.- .beta..times..times..times..beta..times..times..beta..times..times..beta..- times..times..beta..times....

To provide a method and a system for creating a mini time key from a time key, a plurality of mini time keys are created within a unit time period. First, a unit time decryption key is prepared immediately after the unit time is created. Then, the last mini time key is created by applying a one-way function to the unit time decryption key. A desired mini time key is created by applying the one-way function to a mini time key following the desired mini time key. In other words, the mini time keys...

A load balancing method and a corresponding system are proposed. The load balancing method is used in environments (e.g., implementing a licensing management application) wherein each client is associated with a preferred server storing specific information for the client. Each client periodically detects a workload and a response time of all the servers. The client selects a subset of nearest servers (according to their response times). The server in that subset with the lowest workload is set ...

User Assistants are software programs that prompt the customer for information about user's current system by examining system files and other sources of data; store information about the user in a repository for later retrieval or for access by other assistants; present customized instructions to the user on actions to take to complete planning, configuration, and management tasks; perform actions on behalf of the user (e.g., run programs, send e-mail requests, ship order forms) and track the u...

A method and apparatus for providing local data persistence for a Web server application. A Web page provided to a client application (e.g., a Web browser) by the server application contains a data entry area as well as a save button and a restore button. When the user actuates the save button, the Web page dynamically creates a new page that contains the data to be saved and a message prompting the user to save the new page in a user-designated location by using the file-saving function of the ...

An error correction code for encoding the presence of a special uncorrectable error as well as its type. In the encoder, modification logic modifies the regular data symbols to indicate the type of special uncorrectable error. The encoder appends to the regular data symbols a special uncorrectable error symbol indicating the presence of a special uncorrectable error to form an extended data word, which is encoded to generate a code word. In the decoder, a syndrome generator generates a syndrome ...
