  • Patent number: 7877523
    Abstract: An apparatus and a computer program product are provided for completing a plurality of (direct memory access) DMA commands in a computer system. It is determined whether the DMA commands are chained together as a list DMA command. Upon a determination that the DMA commands are chained together as a list DMA command, it is also determined whether a current list element of the list DMA command is fenced. Upon a determination that the current list element is not fenced, a next list element is fetched and processed before the current list element has been completed.

  • Patent number: 7815490
    Abstract: A flash vaporizing liquid jet cutting tool and method for piercing with minimal damage to the cut material. The liquid is preferably superheated water, typically with abrasive particles added after the jet is expressed through a nozzle (abrasive water jet, AWJ) or with abrasive particles added before the jet is expressed through a nozzle (abrasive slurry jet, ASJ). In piercing, only a portion of water that has not changed phase enters into the cavity or must leave the cavity and the piercing pressure, which can damage the material, is therefore reduced.

  • Patent number: 7802300
    Abstract: In one embodiment, an anti-rootkit module compares operating system kernel binary files to their loaded kernel file image in memory to find a difference between them. The difference may be scanned for telltale signs of rootkit modification. To prevent rootkits from interfering with memory access of the kernel file image, a pre-scan may be performed to ensure that paging functions and the interrupt dispatch table are in known good condition. If the difference is due to a rootkit modification, the kernel file image may be restored to a known good condition to disable the rootkit. A subsequent virus scan may be performed to remove remaining traces of the rootkit and other malicious codes from the computer.

  • Patent number: 7559533
    Abstract: An improved electric lift actuator for use on a variety of lift systems, includes various improvements that enable a universal design with interchangeable parts across several load ranges. The universal design further enables additional features and functionality (e.g., improved load cell location, improved operator sensing and electrical signal/air channel in operator pendant, improved reliability and reduced cost for operator force sensing, etc.) In addition the universal design is incorporated with a rotational drive assembly wherein the load sensing and wire rope slack sensing, as well as cable limits may be achieved using improved components and techniques—such as non-contact sensors, etc. Many of the improvements described are believed to reduce cost and improve the performance and expand the capacity and reliability of the actuator in addition to making the actuator a common design across several applications and load ranges.
