Abstract: The application describes a MEMS transducer comprising a substrate having a cavity. The transducer exhibits a membrane layer supported relative to the substrate to define a flexible membrane. An upper surface of the substrate comprises an overlap region between the edge of the cavity and a perimeter of the flexible membrane where the membrane overlies the upper surface of the substrate. At least one portion of the overlap region of the upper surface of the substrate is provided with a plurality of recesses. The recesses are defined so as to extend from the edge of the cavity towards the perimeter of the flexible membrane.

Abstract: A MEMS capacitive transducer with increased robustness and resilience to acoustic shock. The transducer structure includes a flexible membrane supported between a first volume and a second volume, and at least one variable vent structure in communication with at least one of the first and second volumes. The variable vent structure includes at least one moveable portion which is moveable in response to a pressure differential across the moveable portion so as to vary the size of a flow path through the vent structure. The variable vent may be formed through the membrane and the moveable portion may be a part of the membrane, defined by one or more channels, that is deflectable away from the surface of the membrane. The variable vent is preferably closed in the normal range of pressure differentials but opens at high pressure differentials to provide more rapid equalisation of the air volumes above and below the membrane.

Abstract: A method is described. The method includes receiving notice of a page fault.

In response to the page fault, updating page table information to include a translation that points to the page in persistent memory such that the page changes to system memory status without moving the page and system memory expands to include the page in persistent memory.

Abstract: A host based caching technique may be used to determine caching policies for a hybrid hard disk drive. Because the host based caching may make use of knowledge about what data is being cached, improved performance may be achieved in some cases.

Abstract: The application describes MEMS transducers comprising a flexible membrane layer supported in a fixed relation relative to a substrate along at least one supporting edge, wherein a plurality of slits are provided through the membrane layer. The slits define a plurality of beams. Each beam defines a path between first and second endpoints of the beam, the path comprising at least one change in direction. Also described are transducers wherein the membrane layer is supported in a fixed relation relative to the substrate along a plurality of supporting edges which define a membrane region that is substantially bounded by the supporting edges.

The present invention also provides methods of blocking DNA polymerization by an HIV reverse transcriptase enzyme, methods of preventing HIV infection in a female human, methods of treating HIV infection in a female human, methods of preventing unintended pregnancy in a female human, and methods of preparing intravaginal rings.

Abstract: A MEMS transducer and method of forming a MEMS transducer. The MEMS transducer comprises a flexible membrane and a backplate, a membrane electrode being located on a polygon shaped first surface of the flexible membrane, and a backplate electrode being located on a first surface of the backplate facing the membrane electrode. At least one of the membrane electrode and the backplate electrode has an outline shape configured to correspond to a contour of a contour map, the contour map representing relative amounts of displacement of portions of the flexible membrane from an equilibrium position in response to pressure differences generated by incident sound waves.

Abstract: Technologies for protecting data in an asymmetric volume (ASV) that includes a first storage device that supports device-based encryption and a second storage device that does not support device-based encryption. In embodiments the technologies enable disparate capabilities of the storage devices in an ASV to be exposed to a user. When a complete copy of targeted data identified by a user input for encrypted storage is not present on the first storage device, at least a portion of the targeted data stored on the second storage device is rewritten to the first storage device. When a complete copy of the targeted data is stored on the first storage device, one or more security operations are performed to obfuscate or erase any portion of the targeted data stored on the second storage device.

Abstract: An improved handrail for a staircase or ramp. In one embodiment, the handrail includes an elongated member such as a cylinder or bar that spans the length of the staircase or ramp and a riser barrier. The riser barrier has an extender portion and a riser portion. The extender portion of the riser barrier keeps the elongated member a sufficient distance horizontally from the riser portion that a person can slide his or her hand on the rail without interference. The riser portion projects vertically a sufficient distance above the elongated member to deter sliding down the elongated member. Thus, sliding on the member is deterred, while the function of the cylinder as a handrail is preserved.

Abstract: Examples include techniques for emulating a non-volatile dual inline memory module (NVDIMM) in a computing platform using a non-volatile storage device. When a power up event occurs for the computing platform, a host memory buffer may be allocated in a system memory device and a backing store for the host memory buffer may be copied from the non-volatile storage device to the host memory buffer in the system memory device. When a power down event or a flush event occurs for the computing platform, the host memory buffer may be copied from the system memory device to the corresponding backing store for the host memory buffer in the non-volatile storage device. Thus, virtual NVDIMM functionality may be provided without having NVDIMM hardware in the computing platform.
