Abstract: A chair strengthens core muscle groups and promotes circulation along the gluteal and piriformis muscle groups. Locking castors enable the chair to be moved in busy environments, yet fix the position of the chair when needed. A user of the chair may activate a number of massaging elements by rocking side to side, and may perform back stretches while in the seated position. Additional active massaging elements may alert the user and further promote proper use. Adjustable elements allow users to tailor the chair to their specific needs. Embedded energy harvesters supply power to record and transmit data to users to enhance their awareness of their seating position. Thus a versatile seat is provided that is better suited to active environments while broadening the range of elements of core strengthening, massaging, circulation, and seated exercise.

Abstract: A display board system includes a first display board, a second display board, a first clip, and a second clip. The first clip is coupled to the first display board and includes a body and a top portion coupled to the body generally above an upper edge of the first display board. The top portion has an upwardly facing cavity and a downwardly extending tab. The second clip is coupled to the second display board and includes a body and a top portion coupled to the body generally above an upper edge of the second display board. The top portion has an upwardly facing cavity and a downwardly extending tab. The tab of the second clip is receivable in the cavity of the first clip to support the second display board on the first display board.

Abstract: A table includes a support column defining an axis, a base supporting the support column, a worksurface supported by the support column such that the work surface is rotatable relative to the base about the axis of the support column. The table further includes a rotation mechanism including a swing arm housing coupled to the worksurface. The swing arm housing is rotatable in a first angular direction about the axis to rotate the worksurface in a second angular direction about the axis.

Abstract: A table includes a vertical support column and a base. The base includes a first floor engaging portion disposed on a first side of a vertical axis and a second floor engaging portion disposed on an opposite second side of the vertical axis. The first and second floor engaging portions are weighted such that the base has a center of gravity spaced from the vertical axis on the second side of the vertical axis. A worksurface member is supported by the vertical support column and is vertically spaced from the base. The worksurface member is rotatable relative to the base. In one aspect, the worksurface member has an overall length greater than the overall length of the base. In another aspect, a stop limits rotation of the worksurface member.

Abstract: A rail system is used for supporting a plurality of upper and lower modular wall panels adjacent a plurality of spaced apart studs. In one aspect of the invention, the rail system includes an upper rail mounted horizontally to the studs adjacent a ceiling, a lower rail mounted horizontally to the studs adjacent an abutting surface such as a floor, bathtub, or shower pan, and a middle rail mounted horizontally to the studs between the lower and upper rails. Each rail is mountable to the studs regardless of the distance therebetween. The upper rail is adapted to receive an upper portion of the upper wall panels, the lower rail is adapted to receive a lower portion of the lower wall panels, and the middle rail is adapted to receive the upper and lower panels. In another aspect of the invention, an elongated bar is spaced apart from the middle rail and adapted to be mounted longitudinally thereto.

Abstract: A control column includes a housing adapted to be mounted to a side wall of a shower stall adjacent a front edge portion thereof. The housing includes a panel positioned at an angle relative to the side wall and facing a back wall of the shower stall. A shower head assembly extends outward from a top portion of the housing, and water is supplied from a water supply to a bathtub spout or the shower head at a desired temperature and flow rate.

Abstract: A vertically adjustable lavatory assembly includes an outer frame and a carrier frame positioned within the outer frame. The carrier frame is vertically moveable within the outer frame and has a lavatory connected thereto. A lavatory is positioned outside the carrier frame and outer frame, and includes a faucet and a sink basin having an outlet opening therein. A drain line is in fluid flow communication with the sink basin outlet opening and a sewer line, and is adapted to accommodate for changes in the height of the sink basin. A plurality of supply lines are provided for supplying water to the faucet. The supply lines are also adapted to accommodate for changes in the height of the basin.

Abstract: In a single-use device for collecting and holding blood samples, provision is made for an evacuated tube with a closure (stopper) that can be pierced by the tip of a needle, the other tip of which is intended to be inserted into a vein of a patient. Disposed below the said pierceable stopper, and in the tube, is a diaphragm intended to passed through by the needle-tip that pierces the stopper, so as to form a supplementar barrier between the interior of the tube and the environment when the pierceable stopper is removed.

Abstract: Disclosed is a walk-in inspection apparatus for active production of air samples containing vapors of explosives, drugs, or other substances carried by a person. The apparatus includes a U-shaped booth with an open end through which a person walks past walls which may contain a metal detector, then stands in front of a mesh screen facing a vertical end wall containing a vertical array of shaped funnels. Light-transmissive wall sections near the end wall help encourage entry of the person into the booth, and the light colored mesh screen draws attention of a person in the booth away from the darker funnels. In the collection of an air sample a blower outside the booth sucks a large volume of air around the person and horizontally through the funnels in the end wall and through ducts into a collection manifold for subsequent analysis.
