Patent number: 7008456Abstract: A technique for prohibiting access to a computer having a security function when a security device is illegally removed from the computer. The security device is a hardware component that constitutes a part of a security function for a computer. When the security device is illegally removed from the computer, access to the computer is prohibited. Data indicating that the security device is attached to the computer are stored in a nonvolatile memory. Then, when a specific event, such as a power-ON event, is used as a trigger, the procedure for prohibiting the access to the computer is initiated. Following this, based on the data stored in the memory, it is detected that the security device was once attached to the computer and that it has now been removed. If currently the security device is not attached to the computer, although it was attached before, the access to the computer is prohibited.Type: GrantFiled: January 20, 2000Date of Patent: March 7, 2006Assignee: International Business Machines CorporationInventors: Jun Tanaka, Masahiko Nomura, Hideto Horikoshi, Hideyuki Usui, Seita Horikoshi, Fumio Tamura

Patent number: 6886009Abstract: Query routing is based on identifying the preeminent search systems and data sources for each of a number of information domains. This involves assigning a weight to each search system or data source for each of the information domains. The greater the weight, the more preeminent a search system or data source is in a particular information domain. These weights Wi{1=0, 1,2, . . . N] are computed through a recursive learning process employing meta processing. The meta learning process involves simultaneous interrogation of multiple search systems to take advantage of the cross correlation between the search systems and data sources. In this way, assigning a weight to a search system takes into consideration results obtained about other search systems so that the assigned weights reflect the relative strengths of each of the systems or sources in a particular information domain. In the present process, a domain dataset used as an input to query generator.Type: GrantFiled: July 31, 2002Date of Patent: April 26, 2005Assignee: International Business Machines CorporationInventors: Jun-Jang Jeng, Youssef Drissi, Moon Ju Kim, Lev Kozakov, Juan Leon-Rodriquez

Patent number: 6377546Abstract: A method of providing a rate guarantee to individual or groups of flows in a router through intelligent management of buffers. Rate guarantees are provided by intelligently allocating and isolating the buffers available to each flow. In its most basic form, the method applies to output queued network devices with a simple FIFO scheduler, where a number of streams some with rate reservations are sought to be multiplexed onto an outgoing link. The method involves strictly partitioning the buffer into portions strictly reserved for each flow in proportion to its link reservation. This ensures that each stream obtains the link reservation rate in a scalable manner. A particular embodiment of the invention allow for a portion of the buffer to be strictly partitioned while allowing streams full access to the remainder of the buffer.Type: GrantFiled: May 12, 1998Date of Patent: April 23, 2002Assignee: International Business Machines CorporationInventors: Roch Andre Guerin, Sanjay Damodar Kamat, Ping P.
