There is disclosed a recovery node testing system and method. The system and method include copying a protected server image associated with a protected server to a test node and creating a test environment for the test node, the test environment including at least one of the network characteristics of the protected server. The test node may then be activated using the protected server image which may then be connected to the virtual network. Once connected, at least one test is performed on the test node to confirm that the protected server image operating on the test node responds in the same manner as the protected server.

An electronic nutrition journal that can include one or more portable units capable of reading barcodes and serving sizes on consumed food items either on menus or on items purchased. Portable units can communicate with either an intermediate computer or directly with a server computer that contains a master nutritional database relating nutritional data with bar codes. This master nutritional database can be updated by either user input such as user preferred menus or by visiting websites that contain this data. An external barcode generator can be operated to produce barcodes for commercial operations that sell food such as restaurants, food trucks, vending machines or others so that barcodes can be established for their menus or selections. The intermediate computer or the server can track food intake and provide computations of nutritional values, bench marks, etc. a particular user or for many users. The server and master nutritional database, as well as coding of restaurant menus, etc., can be run as a service that a user could subscribe to.

A system and method for patterning a master disk or “stamper” to be used for nanoimprinting magnetic recording disks uses an air-bearing slider that supports an aperture structure within the optical near-field of a resist layer on a rotating master disk substrate. Laser pulses directed to the input side of the aperture are output to the resist layer. The aperture structure includes a metal film reflective to the laser radiation with the aperture formed in it. The aperture has a size less than the wavelength of the incident laser radiation and is maintained by the air-bearing slider near the resist layer to within the radiation wavelength. The timing of the laser pulses is controlled to form a pattern of exposed regions in the resist layer, with this pattern ultimately resulting in the desired pattern of data islands and nondata islands in the magnetic recording disks when they are nanoimprinted by the master disk.

An apparatus, system, and method are disclosed for increasing data storage density in patterned media. One or more deposition sources may apply magnetic material to one or more recesses formed in a substrate, each recess having opposing sidewalls that are effectively coated by the deposition sources. The top surface of the substrate may subsequently be planarized to remove magnetic material from such surface, thereby isolating one or more recordable magnetic regions formed on each sidewall. In this manner, the present invention may provide at least two recordable regions for every recess formed in a substrate.

An airflow shroud for either a moving-slider-type or a moving-head-type microactuator of a disk drive reduces off-track motion of a read/write element for either a moving-slider-type microactuator or a moving-head-type microactuator. One configuration of the airflow shroud includes a frame portion and an attachment portion. The frame portion has an opening suitable for exposing an air bearing surface of a slider for a disk drive and surrounds the slider and a moving-slider-type microactuator coupled to the slider. The attachment portion is adapted for attachment to a suspension of a disk drive. Another configuration includes a plate portion and a recessed portion. The plate portion is attachable to a slider having a moving-head-type microactuator. The recessed portion corresponds to the moving-head-type microactuator of the slider.

This invention is for LLDPE blends with an ethylene-norbornene copolymer for resins and improved toughness and processibility for film production. This invention provides LLDPE based resins which are significantly improved with respect to their capability to be fabricated into a film layer, particularly by a blown bubble extrusion technique. Films prepared of the LLDPE/E-NB melt blended resins of this invention are significantly improved with respect to certain of their film properties, such as tear strength, without detracting from the beneficial properties that a LLDPE otherwise provides to a film.
摘要:
A system for stripping frames transmitted by a station on a token ring network is disclosed. During operation of the system, the station receives a grant of permission to transmit onto the network. In an example embodiment, the grant of permission is a token. After receipt of the grant of permission to transmit, the station transmits one or more frames onto the network. The station counts the number of frames transmitted onto the network. The count of frames transmitted onto the network is the `frame count`. Upon transmission of the frames, the station stops forwarding frames received from the network, thus removing received frames from the network. Removing received frames from the network is referred to as `stripping`. Following transmission of the information frames, the station counts the number of frames stripped from the network. The count of frames stripped from the network is the `strip count`. When the strip count equals the frame count, the station terminates stripping. In an example embodiment, the system is used in a bridge station, the bridge station connecting a first network with a second network.
摘要:
A station transmits a sequence of one or more frames on a token ring, keeping count of the frames transmitted. At the end of the transmitted frame the station originates onto the ring one or more coded marker frames and finally transmits a token. After the station transmission is begun, the station strips from the ring all the frames it receives, decrementing its count for each properly stripped frame, until either its count is reduced to zero or one of its marker frames is detected.

A ring purging station for a token-ring network is disclosed. The station performs purging operations to remove no-owner frames and frame remnants from the network. The station begins a purging operation by detecting the token on the network and removing it. The station then begins stripping all frames and remnants of frames that it receives from the network, and transits one or more purge marker frames. When the station detects one of the one or more purge marker frames it transmitted, it ends the purging operation, and releases the token back onto the ring. In this way no-owner frames and frame fragments are removed from the network, while the ring is otherwise normally operating. In an embodiment of the invention, a sequence number is associated with each purging operation, included in the purge marker frame(s), and verified upon receipt of the purge marker frame(s). The station also corrects multiple token conditions when a multiple token condition is detected during a purging operation. A further aspect of the invention is an election method for selecting a purging station from the stations on the ring.

A subwavelength aperture includes a plurality of ridges that project from an aperture sidewall into the aperture opening. The ridges may be closely spaced such that the hot spots associated with the ridges are likewise closely spaced and create an elongated hot spot. The subwavelength aperture of the present invention may be adapted for use in a magnetic head of a hard disk drive for improved thermally assisted recording (TAR) of magnetic data bits. Such a magnetic head may include an optical resonant cavity that is fabricated within the magnetic head structure.
