  • Patent number: 8719538
    Abstract: A method for protecting memory segments of a memory device is provided. The method includes receiving, by a processor coupled to the memory device, a request to allocate memory from an application, being executed by the processor, wherein the request includes a requested memory size and allocating, by the processor, a portion of memory having a size greater than the requested memory size. The method also includes creating, by the processor, a permitted read counter associated with the allocated portion of memory, wherein the permitted read counter is initialized to an initial value, and determining, by the processor, whether access to the memory segment is permitted using the permitted read counter. A system for protecting memory segments of a memory device is also disclosed.

  • Patent number: 8370689
    Abstract: A method and system for verifying memory device integrity includes identifying at least one memory block corresponding to at least one memory location within a memory device. The memory block is associated with a portion of a file and a checksum representing data within the memory block at a first time. Based at least in part on determining that the memory block is mapped to the same portion of the same file at a second time, it is indicated that the checksum represents expected data within the memory block. A system for verifying memory device integrity is also disclosed.

  • Patent number: 8335951
    Abstract: A method for verifying memory device integrity includes identifying at least one memory block corresponding to at least one memory location within a memory device. The memory block is associated with a prior checksum. It is determined whether the first memory block is designated read-only. A current checksum is calculated based at least in part on data within the memory block. When the first memory block is designated read-only, and the prior checksum represents expected data within the first memory block, it is determined whether the current checksum is equal to the prior checksum. When the current checksum is not equal to the prior checksum, a verification failure for the first memory block is indicated via a notification interface. A system for verifying memory device integrity is also disclosed.

  • Publication number: 20120291873
    Abstract: A hydraulic circuit and method includes a valve subsystem between a high pressure source, a medium pressure source, a low pressure return, and an actuator. The valve subsystem is configured and controllable to drive the actuator using the high pressure hydraulic fluid or the medium pressure hydraulic fluid and also to direct low pressure hydraulic fluid exiting the actuator to the low pressure return. A controller is responsive to high pressure criteria and medium pressure criteria associated with the actuator and is configured to operate the valve subsystem to present high pressure hydraulic fluid to the actuator in response to high pressure criteria and to present medium pressure hydraulic fluid to the actuator in response to medium pressure criteria.

  • Publication number: 20120159085
    Abstract: A method for validating an eligibility for verification of a memory device within an embedded demand paged memory operating system environment is provided. The method includes receiving a request from an application being executed by a processor coupled to the memory device, the request to utilize at least one memory location. The method includes identifying, by the processor, at least one memory block corresponding to at least one memory location within the memory device, determining, by the processor, whether the at least one memory block is eligible for verification, and producing an eligibility result based on the determination by the processor. A system for validating an eligibility for verifying memory device integrity is also disclosed.

  • Publication number: 20070182256
    Abstract: A linear reluctance motor includes a stator with a set of spaced blades each extending in the direction of the actuation axis, each blade including a plurality of alternating low permeability and high permeability teeth. A shuttle also includes a set of spaced blades each extending in the direction of the actuation axis interleaved with the blades of the stator, each blade of the shuttle also including a plurality of alternating low permeability and high permeability teeth. An active component is associated with either the stator, the shuttle, or both. The active component is divided into at least N phases, each phase including a set of blades, a flux return portion, and a coil wound to produce flux through the sets of interleaved blades in a direction substantially transverse to the actuation axis.
