20120027022MULTIPLE SOURCE VIRTUAL LINK REVERSION IN SAFETY CRITICAL SWITCHED NETWORKS - In a system that uses a switched network and virtual links (for example, an AFDX, TT-ETHERNET, or TT-Gigabit ETHERNET switched ETHERNET network), the system is configured so that, for at least one virtual link, the end system that sources frames for that virtual link can change (for example, when an end system that was previously sourcing frames for that virtual link fails). The switches used in such a system are configured to be able to accept frames if there is such a change.02-02-2012

20100232051COMBINED BULK THERMAL-ASSISTER AND BULK ERASER - A combined bulk thermal-assister and bulk eraser. The bulk thermal-assister is configured to produce a temperature in a magnetic-recording disk in a hard-disk drive when the hard-disk drive is disposed in the bulk eraser. The temperature is about equal to a second temperature greater than a first temperature of the magnetic-recording disk. The bulk eraser is configured to erase recorded information from the magnetic-recording disk at the second temperature. The second temperature lowers a coercivity of the magnetic-recording disk so that, when recorded information is erased from the magnetic-recording disk at the second temperature, recorded information on the magnetic-recording disk is erased from a second magnetic-recording track in closer proximity to an inside diameter of the magnetic-recording disk than a first magnetic-recording track from which recorded information on the magnetic-recording disk may be erased, if recorded information were erased from the magnetic-recording disk at the first temperature.09-16-2010

20080314602Portable fire extinguisher with manual and heat-responsive operators - The portable fire extinguisher has a housing, a pair of nozzles protruding from the housing, and a heat-responsive valve mounted outside the housing for detecting high heat intensity at proximity of the housing. The housing contains a cylinder of inert gas under pressure, a reservoir of fire suppressant material, and a piping system connecting the cylinder of inert gas, the heat-responsive valve, and the reservoir of fire suppressant material to the nozzles. The housing has a carrying handle formed thereon and magnets on surfaces thereof for retaining the housing to a range hood in a detachable manner. The piping system comprises a manual valve mounted in parallel with the heat-responsive valve for selective operation of the fire extinguisher in a manual mode. The heat-responsive valve is mounted near the top surface of the housing for detecting high heat intensity as close as possible from the ceiling of a range hood.12-25-2008

20110022570ALLOCATING FILES IN A FILE SYSTEM INTEGRATED WITH A RAID DISK SUB-SYSTEM - Integrating a file system with a RAID array that exports precise information about the arrangement of data blocks in the RAID subsystem. The present invention uses separate current-write location (CWL) pointers for each disk in the disk array where the pointers simply advance through the disks as writes occur. The present invention writes on the disk with the lowest CWL pointer. A new disk is chosen only when the algorithm starts allocating space for a new file, or when it has allocated N blocks on the same disk for a single file. A sufficient number of blocks are defined as all the buffers in a chunk of N sequential buffers in a file. The result is that CWL pointers are never more than N blocks apart on different disks, and large files have N consecutive blocks on the same disk.01-27-2011
