Abstract: A storage server in a storage area network (SAN) environment connecting host computers and storage devices. The storage server includes a plurality of storage processors and a switching circuit. Data is routed between the storage processors via the switching circuit according to routing tags. The routing tags are examined prior to completely receiving the data, allowing the data to be routed with minimal delay.

Abstract: A method and system to enter a time out interval in a storage area network includes identifying a time slot in a sequence of time slots to insert a time out event for the event in the storage area network, determining if other events in the storage network already have corresponding other time out events in the same time slot and inserting the time out event for the event in the identified time slot along with the other time out events and the other corresponding events. Monitoring time out intervals for the events includes receiving a request to determine if events in the storage area network have timed out, identifying events associated with a current time slot, determining if the identified current time slot is empty, removing events from the identified current time slot in response to the determination and notifying a time-out handler to perform appropriate time-out related processing.

Abstract: A sleep system includes sensors capable of gathering sleep data from a person and environmental data during a sleep by the person. A processor executes instructions that analyze this data and control the sleep of the person and the environment surrounding the person. Typically, the instructions are loaded in a memory where they execute to generate an objective measure of sleep quality from the sleep data from the person and gather environmental data during the sleep by the person. Upon execution, the instructions receive a subjective measure of sleep quality from the person after the sleep, create a sleep quality index from the objective measure of sleep quality and subjective measure of sleep quality, correlate the sleep quality index and a current sleep system settings with a historical sleep quality index and corresponding historical sleep system settings.

Abstract: A cache connected to the virtualization engine in the center of a storage area network. The invention caches data in a virtual cache, without requiring translation to the physical location. The cache is done as the data crosses the network through the virtualization engine, eliminating the need to do the further translation and forwarding over the network to the actual storage controller in the event the data is in the cache. In addition, the invention eliminates the need for multiple caches at each physical storage controller.

Abstract: Apparatus and method offloads processing from a networking processor operating in a storage environment. Three main functions are offloaded: semaphore processing, frame order processing, and timer processing. Offloading of semaphore processing enables ordered access to semaphores. Offloading of frame order processing enables the network processor to quickly transmit an incoming frame if the incoming frame is the next one in the frame order. Offloading of timer processing enables background checking of the timer list.

Abstract: A portable magnification stand includes a lower inner plane area surrounded by and held in place by a lower coplanar support material. A back pair of adjustable arms and a front pair of adjustable arms are mounted to the lower planar base unit and an upper planar lens unit that holds a lens for magnifying objects. The back pair of adjustable arms are longer than the front pair of adjustable arms causing the magnification of objects to appear greater near the front portion of the upper planar lens unit compared with objects near the near the back portion of the upper planar lens unit. Swingable extensions shaped as trapezoidal planar materials can be used in lieu of the adjustable arms to provide the appropriate magnification in a more compact and lighter weight design.

Abstract: A method and interface for finding image intensities of an image on a computing device is provided. Finding these image intensities includes displaying an image on a display device having a range of intensities, identifying one or more regions of the image according to the intensity values in each of the one or more regions, categorizing each region as falling into one intensity zone category from a set of intensity zone categories according to the intensity value for each region and displaying the image on the display device with the regions and corresponding related intensity zone categories highlighted.

Abstract: In a storage server on a storage area network, a media unit manager manages disk space in a manner transparent to the host computers. The media unit manager uses media units corresponding to the physical storage devices on the storage area network to build higher-level media units. The higher level media units can have the attributes of being sliced, concatenated, mirrored, striped, etc. Thus, the host computers need not be aware of the specific physical storage devices themselves, reducing the management and reconfiguration burden on the host computers when storage devices are added to or removed from the storage area network.

Abstract: A method and system for provisioning storage from a storage area network is provided. The provisioning includes receiving a request for a storage size and storage configuration from a storage area network according to a storage profile, identifying a storage device pool of storage devices according to a storage device candidate strategy, selecting a media unit provisioning strategy based upon the type of storage configuration specified in the storage request, generating media unit solutions using the media unit provisioning strategy and sequence of storage devices in the storage pool, determining if the media unit provisioning strategy produced a solution for the requested storage configuration and provisioning a media unit solution in response to the determination.

Abstract: A storage virtualization controller for transferring data between a host and a storage device at a wire-speed data transfer rate. A downstream processing element adapted for connection to the storage device is configurable coupled to an upstream processing element adapted for connection to the host. A central processing element coupled to the upstream processing element grants permission to the upstream processing element to transfer the data at the wire-speed rate without further involvement by the central processing element.

Abstract: An automated, policy-based system and method provides information security at various levels in the network, including at the baseline inventory, device, network frame, and command level. This approach improves over the conventional distributed security model by centralizing security in one multi-level management structure. Embodiments of the present invention may also provide a scheme for mapping vendor-unique opcodes to access rights.

Abstract: A storage virtualization system for accessing at least one storage device for a virtual logical unit (VLUN) from at least one host. The system includes at least one upstream processing element (UPE) which is adapted for coupling to a corresponding host server. The system is further adapted for coupling to at least one storage device. The controller also includes a primary central processing element (CPE) that can be configurably coupled to the UPEs. The primary CPE permits data transfer to occur between a host and a storage device via the corresponding UPE. The controller further includes a backup CPE that can be configurably coupled to the UPEs. The backup CPE is configurable to permit the data transfer when the primary CPE becomes unavailable.

Abstract: A method and apparatus is used to detect and compensate for printhead rotation in an inkjet printer. The detecting operation includes receiving an initial image of a pattern taken from a medium as the printhead passes over the medium, receiving a subsequent image of the pattern taken from the medium as the printhead continues to pass over the medium, comparing the initial image of the pattern and the subsequent image of the pattern taken from the medium and identifying a rotation of the printhead in the inkjet printer passing over the medium if the comparison indicates the initial image of the pattern is rotated relative to the subsequent image of the pattern. The compensation operation includes modifying the timing settings associated with the firing of the nozzles in the inkjet printhead to compensate for the rotation of the printhead.

Abstract: A reaction frame having a first reaction frame portion and a second reaction frame portion receives reaction forces from a stage. First reaction frame portion is coupled to ground by a ground rod aligned along the longitudinal side of the first reaction frame portion; second reaction frame portion of the reaction frame is coupled to an interconnect rod passing parallel to the plane defined by the first reaction frame portion and second reaction frame portion. Ends of interconnect rod have a damper therebetween. One end is coupled to the first reaction frame portion while the other end is coupled to the second reaction frame portion. Reaction forces in received by the second reaction frame portion are transferred to ground through the interconnect rod and the first reaction frame portion. Alternately, the interconnect rod does not use the damper when alligned with the ground rod.
