Patent number: 6385226Abstract: A laser diode array assembly includes a laser diode array and a memory device integrally packaged with the array. The memory device includes operational information concerning the array. The memory device is accessible by a host external operating system which determines the manner in which the array is to be powered based on the operational information. The memory device may have the capability to be written to such that tie external operating system can record in the memory device significant events such as extreme operational conditions, operational faults, and the on-time or shot-count of the array. The assembly may include sensors to which the operating system is coupled. The assembly may further include a processing means to monitor the sensors and provide real-time updates to the external operating system such that laser diode array is continuously powered in an optimal manner.Type: GrantFiled: August 6, 2001Date of Patent: May 7, 2002Assignee: TRW Inc.Inventors: Theodore S.

Patent number: 6111876Abstract: In a network device such as a network switch having a port coupled to a communications medium dedicated to a single virtual local area network and another port coupled to a communications medium shared among multiple virtual local area networks for transmitting data frames between the dedicated communications medium and the shared communications medium, a method of identifying the virtual network associated with each data frame received by the network switch when transmitting the data frames over the shared communications medium. The method comprises receiving data frames from the dedicated communications medium coupled to one port, and, with respect to each data frame so received, inserting a new type field and a virtual network identifier field. The contents of the new type field indicate the data frame comprises a virtual network identifier field.Type: GrantFiled: August 30, 1996Date of Patent: August 29, 2000Assignee: Nortel Networks LimitedInventors: Paul James Frantz, Geoffrey O.

System for allocating and returning storage and collecting garbage using subpool of available blocks
Patent number: 5561785Abstract: A computer storage management system establishes a subpool of available blocks of one size from a multiplicity of different storage frames. The available blocks are queued in the subpool. A garbage collection routine periodically or occasionally determines which of the frames having blocks on the subpool queue are completely available based on the number of available blocks on the queue for each frame. Then, the garbage collection routine removes from the queue and thereby reclaims the blocks of the frames which are completely available. The garbage collection routine also requeues the blocks from the other frames such that the blocks of these other frames are clustered with the other blocks of the same frame. Blocks are allocated from the front of the queue. Blocks of the one size from frames other than those represented at or near the end of the queue are returned to the front of the queue after use.Type: GrantFiled: October 29, 1992Date of Patent: October 1, 1996Assignee: International Business Machines CorporationInventors: Geoffrey O. Blandy, Arthur J. Samodovitz -
Patent number: 5390315Abstract: A computer system allocates locations in DASD to store a specified length of data. The allocation attempts to minimize the number of I/O operations and seek time for accessing the DASD. The system records addresses and lengths of sets of contiguous available storage locations in the DASD. Then, the system searches the record to attempt to identify a set of contiguous available storage locations having the specified length and another set of contiguous available storage locations having a length which exceeds the specified length by an amount likely to accomodate most lengths of data subsequently to be stored on the DASD.Type: GrantFiled: June 15, 1992Date of Patent: February 14, 1995Assignee: International Business Machines CorporationInventors: Geoffrey O.

Patent number: 5317754Abstract: An apparatus and method are established for recognizing guest virtual machines which require only a subset of interpretive execution facilities. The interpretive execution initialization process recognizes subset candidates and bypasses initialization of those facilities not required by the candidates. The candidates are typically short duration jobs and a reduction of initialization and termination overhead creates a substantial performance improvement. The translation lookaside buffer operation is modified to flag subset guest entries as host entries and to associate a unique segment table origin with each subset guest. This allows the TLB entries to remain between guest machine dispatches eliminating TLB purge time and allowing potential reuse of TLB entries if the same guest is repeatedly dispatched within a short time period. The guest machine state description is modified to flag subset candidates based on address translation and timing requirements.Type: GrantFiled: October 23, 1990Date of Patent: May 31, 1994Assignee: International Business Machines CorporationInventors: Geoffrey O.
