An indication is provided when the current configuration of the computer system differs from the reference configuration.

Abstract: A secure client/server system allows remote access to a database system without allowing unauthorized users to access data stored within the database system. A server encrypts and transmits a new encryption key to a remote client for each data session established between the server and client. Thereafter, the server and client encrypt the data communicated in the data session with the new encryption key transmitted to the client. The client then transmits a log name and a password to the server. The server verifies that the user of the client is an authorized user and translates the password into an alias password. The server receives a request for data from the client and utilizes the alias password to retrieve data associated with the request for data from a database at the premises of the server. If the request for data is associated with any data located in a remote database system, the server submits a request for data to the appropriate database system.

Abstract: The certification of electronic documents for subsequent verification and authentication is disclosed. Pursuant to a request to certify a document, a digital signature is extracted from the document. The digital signature corresponds to the content of the document and is unique to the document. Thus, signatures extracted from documents that are even slightly different from the certified document, or from a document that has been changed, will be different. A certification provider maintains the digital certification signature, an identification code such as a serial number, and other information such as the time and date of certification. The serial number is returned to the certification requester. When verification is sought, the serial number and the document alleged to have been certified are given to the certification provider. The serial number is used to index the previously extracted digital certification signature.

The user is identified by using the communication between an information apparatus and a battery pack to read out passwords, and a communication section controls to turn on a second switch when the passwords correspond so that power is supplied to a device load.

Abstract: A memory clock control system and method facilitates power reduction on a dynamic basis by detecting memory access request loading from a number of memory access devices, such as video and graphics engines. Based on the detected memory access requirements, the system and method adaptively varies a memory clock frequency in response to determining the desired memory usage at a given point in time. The memory clock is varied based on the priority of a given memory access engine, such that the clock is kept or increased to a higher rate for high priority engines such as real-time processing engines to facilitate high performance video capture.

Abstract: In an object oriented computer system, one or more run-time extensible items are defined that may be dynamically reconfigured as required to support different interfaces at run-time. The behavior associated with these interfaces is supported by one or more extensions owned by the extensible item. Each extension class has a corresponding method table that is shared among instances of the extension class and that correlates the methods defined on the extension class to method node objects that carry out the method. A method repository is a static object that is created at run-time to correlate extensions to their corresponding method tables. When a client invokes an invokeMethod() method on an extensible item, specifying the name of the method to be invoked, the extensible item cycles through its extensions, from newest to oldest, looking for an extension that supports the named method.

Abstract: A queuing architecture and method for scheduling disk drive access requests in a video server. The queuing architecture employs at least two access request queues for each disk drive within a disk drive array. The first queue is for disk access requests by steady-state users who are currently viewing a program from the video server. The second queue is for all other types of access requests including disk access requests by users who wish to begin viewing a program, content loading, meta-data syncing and the like. The method maintains time deadlines for steady-state disk access requests and services these requests in order of ascending deadlines. Requests from the second queue are serviced only if it can be guaranteed that all of the steady-state requests in the first queue will meet their time deadlines in the worst case access time for the disk drive. By taking advantage of the variability of disk seek and transfer times, the method improves the effective disk bandwidth of the video server.
