  • Publication number: 20170300430
    Abstract: Mechanisms to protect the integrity of memory of a virtual machine are provided. The mechanisms involve utilizing certain capabilities of the hypervisor underlying the virtual machine to monitor writes to memory pages of the virtual machine. A guest integrity driver communicates with the hypervisor to request such functionality. Additional protections are provided for protecting the guest integrity driver and associated data, as well as for preventing use of these mechanisms by malicious software. These additional protections include an elevated execution mode, termed “integrity mode,” which can only be entered from a specified entry point, as well as protections on the memory pages that store the guest integrity driver and associated data.

  • Patent number: 9751848
    Abstract: A catalyst, method of using, and use of a hydrogenation catalyst, preferably palladium on a support, preferably alumina or activated charcoal support. This in the presence of lithium salts, with salts such as the borates being preferred. This provides hydrogenation of precursors to give rise to a stereoselective, such as diastereoselective bias in the product of alkene hydrogenation using the catalyst.

  • Publication number: 20170169698
    Abstract: Integrated physical and logical security management is extended to a mobile device, such as a portable wireless device or radio. The Mobile-IMPACT solution extends the reach of authorized users to handheld devices for monitoring, managing and/or controlling of IT/network and physical security. Allowing authorized users to view and control access events while not in their office and logged into their console, mobility within and outside of a facility or campus organization no longer requires a laptop computer. With new handheld technologies more widely accessible and dropping in price while still gaining additional functionality, a chief security officer and their security staff can now monitor access to their building/doors/control zones, look-up user and card information, trigger queries/reports, set new alarm conditions and monitor sensors or a perimeter from a handheld device anywhere in the world using an electronic communication medium, such as a PDA, cell phone, radio, or the like.

  • Publication number: 20170094474
    Abstract: A mobile device that can optionally communicate with a server, the mobile device including latitude/longitude determining capabilities, a display, a data communication system and a power source. The mobile device can be used to communicate, provide location information, track an individual, as well as allow alerting, such in a case of an emergency. This location information could be accompanied with one or more of video information, audio information, multimedia information, and pictures taken by the mobile device. The mobile devices also allow inner-communicability among the devices such as text messaging, chat, voice communications, and the like. The capabilities of the mobile device can also be used to determine if the device has traversed a geo-fence, or defined electronic perimeter, with the crossing of the perimeter capable of triggering special functionality such as the turning on of the mobile device, or smart phone, sending an alert, altering functionality, or the like.

  • Patent number: 9480248
    Abstract: The invention comprises a device and method for impacting the behavior of invertebrates that infest wood, without the use of chemicals. In particular, the invention is useful for impacting the behavior of wood-boring invertebrates, which infest wood products, lumber and the woody portions of plants and trees. The invention utilizes acoustic (sonic) agents which may be optionally modulated with specific signals, to cause negative effects on the normal behaviors exhibited by wood-infesting invertebrates, which may result in the invertebrates being injured or killed, unable to reproduce, or caused to flee the wood that the invertebrates are infesting.

  • Patent number: 9331869
    Abstract: The input/output request packet (IRP) handling technique includes determining if a received input/output request packet should receive a given handling. If the input/output request packet should receive the given handling, the input/output request packet is dispatched to a device specific dispatch input/output request packet handler. Otherwise, the input/output request packet is redirected to an operating system dispatch input/output request packet handler.

  • Patent number: 9135596
    Abstract: A method can include determining a number of cases received (e.g., a case load), a number of cases processed (e.g., a case rate), and dividing the case load by the case rate. The resource demand can be compared to a resource allocation, and the resource allocation can be changed based upon the resource demand. A information handling system can include a processor and a memory. The memory can have code stored therein, wherein the code can include instructions, which, when executed by the processor, allows the information handling system to perform part or substantially all of the method.

  • Publication number: 20150149733
    Abstract: Method and system for supporting speculative modification in a data cache are provided and described. In one embodiment, a speculative cache buffer includes a plurality of cache lines and a plurality of state indicators. At least one of the cache lines is operable to receive an evicted cache line from a cache. The at least one of the cache lines is operable to return the evicted cache line to the cache if the cache requests the evicted cache line. Further, the plurality of state indicators is operable to indicate a state of a corresponding cache line of the cache lines.

  • Publication number: 20150083121
    Abstract: A portable life support apparatus (1102) and particularly a respiratory support apparatus adapted to be easily mounted to a stretcher is disclosed. Prior devices that attach onto a stretcher are heavy and cumbersome and obstruct access to the patient. Accordingly, there is a great need for a portable emergency support device that overcomes the weight, size, positioning, and other portability disadvantages. One aspect relates to a portable life support device including at least one ambient gas inlet (14); a conditioned gas outlet (30); an oxygen concentrator (26,28) fluidly connected between the at least one gas inlet and the gas outlet, and a ventilator (44) fluidly connected downstream from the oxygen concentrator.

  • Publication number: 20150082541
    Abstract: In one aspect, the invention is directed to a connector for connecting a medical device to a support member on a patient support device, such as a stretcher. The connector includes a support member connector that is fixedly connectable to the support member and a device connector for fixedly connecting to the medical device. The device connector is movable relative to the support member connector between a first position wherein the device connector is positioned to hold the medical device adjacent the patient support device and a second position that is inboard of the first position relative to the patient support device.

  • Publication number: 20140281392
    Abstract: The disclosure provides a micro-processing system operable in a hardware decoder mode and in a translation mode. In the hardware decoder mode, the hardware decoder receives and decodes non-native ISA instructions into native instructions for execution in a processing pipeline. In the translation mode, native translations of non-native ISA instructions are executed in the processing pipeline without using the hardware decoder. The system includes a code portion profile stored in hardware that changes dynamically in response to use of the hardware decoder to execute portions of non-native ISA code. The code portion profile is then used to dynamically form new native translations executable in the translation mode.

  • Publication number: 20140189310
    Abstract: In one embodiment, a method for identifying and replacing code translations that generate spurious fault events includes detecting, while executing a first native translation of target instruction set architecture (ISA) instructions, occurrence of a fault event, executing the target ISA instructions or a functionally equivalent version thereof, determining whether occurrence of the fault event is replicated while executing the target ISA instructions or the functionally equivalent version thereof, and in response to determining that the fault event is not replicated, determining whether to allow future execution of the first native translation or to prevent such future execution in favor of forming and executing one or more alternate native translations.
