  • Publication number: 20190262201
    Abstract: A patient support apparatus may include a support surface configured to conduct air along a top face of the support surface so that heat and moisture from a patient lying on the support surface are drawn away from the top face of the support surface. An opening may be formed in a side of the support surface. A cavity may extend from the opening into the support surface. An inlet port may be positioned within the cavity and fluidly coupled to the top face. A blower assembly may be configured to position within the cavity. The blower assembly may have an outlet port that couples to the inlet port when the blower assembly is positioned within the cavity. The blower assembly may conduct air through the inlet port to the top face of the support surface.

  • Patent number: 10375111
    Abstract: Anonymous containers are discussed herein. An operating system running on a computing device, also referred to herein as a host operating system running on a host device, prevents an application from accessing personal information (e.g., user information or corporate information) by activating an anonymous container that is isolated from the host operating system. In order to create and activate the anonymous container, a container manager anonymizes the configuration and settings data of the host operating system, and injects the anonymous configuration and settings data into the anonymous container. Such anonymous configuration and settings data may include, by way of example and not limitation, application data, machine configuration data, and user settings data. The host operating system then allows the application to run in the anonymous container.

  • Patent number: 8364905
    Abstract: A storage system is disclosed including storage devices configured to store data, and a logical storage volume coupled to the storage devices and configured to store a subset of the data as segments. The storage system also includes a controller including a cache and memory. The memory is configured to include records such that each record corresponds with a segment in the logical storage volume and each record includes information regarding data stored in the corresponding segment. The controller is configured to access the records in response to a cache miss of the cache to determine if requested data from the cache miss is stored and ready for access in the logical storage volume. The controller is also configured to update the subset of data stored in the segments as a function of cache misses.

  • Patent number: 7391388
    Abstract: A system and method for producing spectrally segmented images of object fields. In one embodiment the system includes an optical system that focuses light received from an object field along a focal plane with a field stop positioned within the optical system that has plural apertures for selectively transmitting the light from the object field. A diffractive element is positioned within the optical system to spectrally spread, along the focal plane, the light transmitted through the apertures. The apertures can be parallel slots or geometrically arranges holes. The plural apertures are spaced such that the spectrally spread light transmitted through any given aperture and incident upon the focal plane does not overlap on the focal plane with the light transmitted through any other aperture. The diffractive element may spread light across one or more directions. In one embodiment, a processor is coupled to a plurality of pixels in a focal plane array.

  • Patent number: 7281089
    Abstract: Storage controllers and related methods of operation are described. One method tracks storage access operations to a logical disk. The method persistently identifies storage blocks that have been accessed. Responsive to the identifying, the method selectively skips subsequent operations to storage blocks that have not been accessed.

  • Patent number: 7028177
    Abstract: A system and method for synchronizing firmware revisions in redundant controllers in a storage system is disclosed. Redundant controllers transmit firmware revision numbers during the establishment of a communication links between the controllers. The revision numbers are compared and, if they are not equal, then controller that possesses the more recent firmware revision transmits its firmware across the communication link to the other controller. The more recent firmware is stored in the memory of the other controller, which is then re-booted to ensure that both controllers are operating with the same firmware. If a failed controller is replaced or rebooted while the other controller remains operational, then the firmware revision from the operational controller is transmitted to the replaced or re-booted controller and stored in its memory. The controller is then re-booted to ensure that both controllers are operating with the same firmware.

  • Patent number: 6898668
    Abstract: A method of operating a storage controller that receives data access requests containing a logical block address and a count of blocks involved in the access request. A record is generated and persistently stored indicating whether particular logical block addresses have been accessed since creation. The persistent record is subsequently accessed to enable selected operations to be skipped or aborted when they selected operations involve logical block addresses that have never been accessed.

  • Patent number: 6788273
    Abstract: A compensated radome is provided, comprising an inner layer of a negative index of refraction material, often referred to as a “metamaterial”, and an outer layer of a positive index of refraction material. The thickness of the two materials and their respective refractive indices are adjusted so that a beam of light passing through the radome is effectively not refracted. The metamaterial-compensated radomes solve the bore sight angle problem with a minimum of complexity.

  • Patent number: 6756932
    Abstract: A method of absorbing microwave radiation is provided. The method comprises placing a structure in the path of the microwave radiation, the structure comprising an array of metal plates supported over a metal substrate by vertical conducting vias. The structure finds specific use in missiles having a dome portion that operates in a stealth mode. At least the inside of the dome portion is provided with the above-described structure for absorbing microwave radiation. The structure also finds use in anechoic chambers for use in testing microwave-emitting devices. Such anechoic chambers have walls, a floor, and a ceiling, which are provided with the above-described structure for absorbing microwave radiation. Surface patterning is thus used to enhance the micro-wave absorption. In addition, the frequency over which the material is highly absorptive can be shifted by changing the height of the structure, thus allowing active control (“tunable in real time”).
