Abstract: A device for supporting a standard size keyboard tray within an electronics rack or cabinet. The keyboard supporting device includes a slideable shelf and a keyboard tray that is rotatably mounted thereto. The keyboard tray is rotatable between a storage position in which the keyboard tray is substantially perpendicular to the slideable shelf and a use position in which the keyboard tray is substantially parallel to the slideable shelf. A biasing device is included for biasing the keyboard tray toward either the storage position or the use position when the keyboard tray is disposed between the use position and the storage position.

Abstract: An apparatus for retaining and controlling the size of pieces of snow and/or ice accumulating on a roof contains brackets secured to the roof and rails passed between the brackets to form a frame structure. The brackets have slots and/or pockets for fitting rails and enable the rails to be at or below the level of seams on seamed roofs and at a low profile with non-seamed roofs. In addition, the brackets may be attached to the roof without penetrating the roof structure. A method of installing a snow and/or ice retaining apparatus includes lowering the rails into pockets on the brackets, sliding the rails into slots on the brackets, and, optionally, securing the rails with a clip, wedge, or adhesive.

Abstract: A packet interception system intercepts message packets transmitted from a packet source or to a packet destination, and processes them so as to facilitate verification of the contents and the sequence with which the message packets are intercepted, and for storing the processed message packets for later use. The packet interception system generates for each intercepted message packets respective hash values based on the respective intercepted message packet and the hash value generated for the previously-intercepted message packet, or, for the first intercepted message packet, a value that is provided to identify the session. To verify a previously-stored intercepted message packet, the packet interception system, or another device, using the same hash algorithm, can process the sequence of stored intercepted message packets up to and including the intercepted message packet to be verified, to and compare the hash value generated to the previously-generated hash value for each of the message packets.

Abstract: The present invention relates to a winding device and a flying toy ornithopter device which employs the winding device. The flying toy ornithopter comprises a hollow body which simulates the appearance of a bird, insect or flying machine. A pair of wings are provided which oscillate, the wings are powered by the stored energy of a wound rubber band. One end of the rubber band is connected to a hook mounted in the tail of the hollow body, the other end of the rubber band is mounted to a winding device mounted near the head of the hollow body. The winding device comprises a frame which has a generally oval shape and conforms to the cross-sectional of the hollow body to mount therein, a central annular bore and a pair of lugs located at the periphery of the frame to which the wings are attached; a pin projects from the frame toward the front of the hollow body for the attachment of a locking lever.

Abstract: In a complex machining machine tool, a tool rest capable of attachably and detachably installing tool installing inserts thereon is provided, a plural number of virtual tools is set and registered concerning a predetermined at least one tool together with its indexing positional data in tool file, the tool data of the corresponding virtual tool is read out from the tool file on the basis of the machining instruction by the virtual tool stored in machining program, and the corresponding virtual tool is indexed on the tool rest on the basis of the indexing positional data, and then machining with the virtual tool is executed. At the time of machining, it is possible to continue machining with the same tool by only positional indexing without changing the tool. The work for changing tools can be extremely decreased even if machining contents are changed or it is necessary to change tools by tool exhaustion.

Abstract: A two-sided keyboard or other input/control device (19) has first and second keyboards (25, 29) mounted so that their respective keys face in substantially opposite directions. Each of the keyboards (25, 29) can correspond to a different need, user preference or computer application, including different language characters, different input controls, and different key configurations. The two keyboards are mounted in a single keyboard module (35) which can be flipped or rotated so that the desired keyboard faces up. In one preferred form, the keyboard module (35) plugs into a base (39). An electrical connector (51a, 51b) is provided for each of the keyboards (25, 29), so that the selected keyboard can be connected to a corresponding connector (49) on the base (39).
