  • Patent number: 7878128
    Abstract: A system includes a board having opposing surfaces and at least one leg connected to one surface of the board through a first pivotable fitting to allow the board and the leg to move between a first position wherein the board and the leg are substantially parallel and a second position wherein the board and the leg are substantially perpendicular. The system also includes a locking mechanism secured to the board through a second pivotable fitting at a first end and configured to rotate at a second end opposite the first end between a storage position extending parallel with the board and a work position extending perpendicular to the board.

  • Patent number: 7644991
    Abstract: A chair for offices and the like includes at least one armrest that can be folded from a generally upright position to a folded position and visa-versa. The folding mechanism has a thin profile, thereby minimizing the thickness of the armrest and providing an aesthetically pleasing appearance. A cover for the armrest includes an elastic material that stretches to accommodate folding, and also contracts to reduce or eliminate wrinkles. The folding mechanism may bias the armrest to the folded position to overcome forces generated by stretching of the cover when the armrest is folded.

  • Publication number: 20090212607
    Abstract: A seating unit includes a tubular support extending upwardly from a chair frame, a retainer telescopingly engaging an upright open end of the support, and an armrest mounted on the retainer. The retainer is keyed at both ends to prevent undesired rotation of the armrest. Accessories are mounted to the retainer, and are positionable at use and non-use positions relative to a seated user. The accessories include a cup holder, a container, a hook for hanging items under the cup holder or container, and different tablets. One tablet includes a wheeled leg that extends downwardly from a center of gravity of the tablet, the leg supporting the tablet and reducing cantilever forces on the retainer. The back and seat comprise a flexible member co-molded onto a supportive partial-perimeter frame member and includes back and seat sections that matably engage corresponding surfaces of the frame member.

  • Patent number: 7519598
    Abstract: In a computer network, network management applications in a network management station manage and control managed elements connected to the network through the use of network management requests. The network management requests are prioritized by the management station or the managed element. The managed element prioritizes received requests by pre-assigning priority values corresponding to user identification values included in the request or by pre-assigning priority values corresponding to source identification values included in the request. The management station prioritizes the network management requests by adding a priority value to each network management requests before sending the request to the managed element. The managed element extracts the priority value directly from the request or dependent on the user identification or source identification included in the request.

  • Patent number: 6895868
    Abstract: A conference table includes a work surface having one or more central openings. A utility distribution system is position below the central opening on a support channel. The support channel defines separated wireways for communicating separated utilities along the support channel. The utility distribution system further includes a plurality of W-shaped utility modules positioned on beams of the channel below the central opening. The utility modules set end-to-end in an arrangement that facilitates initial installation and later retrofit or repair. The table is supported on legs that define a vertical wireway space, and further include a repositionable divider configured to selectively subdivide the vertical wireway space into subwireways of different cross-sectional sizes for accommodating different cross-sectional sizes of utility conduit bundles. A removable double-pivoted door is releasably supported to cover the opening and to provide easy access to the opening from either side of the table top.

  • Patent number: 6721824
    Abstract: A method and apparatus assists communication between a writer of a shared file and the reader of the shared file without requiring the use of a shared file. When the writer fills a buffer with information and provides a write commend to write the buffer to a shared file, the buffer is not written to a file. Instead, the pointer to the buffer is passed to the reader, and the writer may be suspended until the reader indicates it has read the file. Alternately, two buffers may be used, with the contents of the buffer used by the writer copied to a second buffer, allowing the writer to reuse the first buffer before the reader has completed reading the contents of the second buffer.

  • Patent number: 6643866
    Abstract: A toilet-seat positioner has a base frame (1) with a first-side rod (2), a second-side rod (3) and a frame-front rod (4). The first-side rod is made to be placed beside a first side of a toilet bowl (5). The second-side rod is made to be placed beside a second side of the toilet bowl. The first-side rod and the second-side rod are attached to the frame-front rod for bracketing the toilet bowl. In the absence of a toilet bowl between the first-side rod and the second-side rod, the base frame can be positioned over a portable defecation container (22) which can include a bed pan, a pot or a portable toilet. A first pneumatic cylinder (10) has a bottom end attached pivotally to an aft end of the first-side rod. A second pneumatic cylinder (11) has a bottom end attached pivotally to an aft end of the second-side rod.
