Abstract: Some embodiments of the invention provide a method for defining code-based policies. The method generates a policy-builder first view of a policy for display in a graphical user interface (GUI) by processing a syntax tree that is generated from a code second view of the policy. The method receives, through the policy-builder first view, a modification to a portion of the policy. To reflect the modification, the method updates a portion of the syntax tree that corresponds to the portion of the policy that is affected by the modification. Based on the updating of the syntax tree, the method updates the code second view by modifying a portion of the code second view that corresponds to the updated portion of the syntax tree.

Abstract: The problem of contamination of sterile splash basins and surgical instrumentation used in operating rooms is solved by the use of an aqueous composition containing chlorhexidine gluconate in a concentration of sufficient strength to provide inhibition of bacterial growth and disinfection of surgical instruments, but is not harmful to non-mucosal tissues. Pre-filled bottles of the aqueous composition are also provided, with drip-free mouths that minimize contact with the exterior of the bottle. Also disclosed are pre-filled splash basins with removable covers that help maintain sterility. Also disclosed are pre-filled ampoules in sterile wrappers for dilution into sterile splash basins with dispensed sterile water.

Abstract: The present invention is directed to a scented picture frame having removable scent boards attached in spaced relation to provide an aromatic ambiance with the display of an item such as a picture. The present invention features a holder on the back of the frame, capable of holding one or more scent boards in parallel adjacent the back of the frame, whereby an aroma is dissipated from a scented oil on the scent board to enhance the experience of viewing the item. Scents are impregnated into the scent board and retained by individually wrapping the scent boards for future use. One or more scents may be used with the present invention by hanging multiple scent boards on the scented picture frame. The scent boards may be removed and replaced when the scent is dissipated or to change the aroma. A picture pouch is used to protect the item in the scented picture frame from absorbing an aroma of the scent board.

Abstract: A latch arrangement for a drawer includes a latching mechanism having a latch element and a latching mechanism-receiving structure formed as part of a drawer. The structure includes two integral spring elements for biasing the latching mechanism upwardly. The latching mechanism and the drawer have cooperating, snap-engageable retaining features that allow the latching mechanism to move over a vertical range of movement but retain the latching mechanism on the structure. The structure and the remaining portions of the drawer can be molded as a unitary plastic part. The latching mechanism can be molded as a second unitary plastic part.

Abstract: A method and apparatus for retaining heat at a pin-in-hole rework site on a printed circuit board during solder fountain rework of the board. A preheated heat retention plate is attached to the rework side of the printed circuit board. The heat retention plate covers a substantial portion of the board surface. During rework of the printed circuit board, the heat retention plate minimizes the temperature gradient between the rework site of the printed circuit board and the remainder of the printed circuit board. During the rework, the heat retention plate can be heated by an active heater in order to maintain a constant temperature gradient between the rework site of the board and the remainder of the board. By minimizing the escape of heat from the rework site, the number of solder cycles required to rework the board is decreased, resulting in reduced board rework times and increased board longevity.

Abstract: A clutch and a workpiece support incorporating the same selectively restrict rotation of a rotatable member through the use of one or more rollers that are pinched between the outer surface of the rotatable member and corresponding convergent surfaces disposed on a housing opposing such outer surface. In effect, each roller is interposed between a surface on a fixed housing and an outer surface of a rotatable member such that rotation of the rotatable member rolls the roller toward a converging gap to restrict further rotation of the rotatable member. A biasing mechanism biases the roller toward the converging gap, and a release mechanism is utilized to quickly and efficiently decouple the roller from the rotatable member by biasing the roller in a direction away from the converging gap and thereby preventing the roller from inhibiting rotation of the rotatable member.

Abstract: Circuit boards are formed within the boundaries of an insulative sheet or panel such that the panel may be automatably processed. The periphery of each printed circuit board is defined by at least a plurality of score lines which do not extend to the edge of the sheets and may include also uncut and/or unscored areas to provide stability to either the sheet or segments of scrap material, lending rigidity to the sheet. Following complete fabrication of the printed circuit board, the sheet is cut by a routing process to extend selected score lines to the edges of the sheet to destroy the integrity of the frame of scrap material surrounding the printed circuit boards.

Abstract: An electronic system contains a backplane circuit card assembly for distribution of electrical signals among component devices. Power is distributed in embedded power planes, one of which is associated with ground. The backplane also contains multiple embedded ground planes. The circuit card assembly is divided by an axis into two halves, each half receiving and consuming approximately equal power. Electrical couplings for power sources and power planes in each half of the backplane are located symmetrically with respect to the axis. A row of ground vias along the axis couples the ground planes to the associated power plane. At all other locations on the backplane, the ground planes are electrically isolated from the associated power plane. Preferably, the backplane assembly comprises a pair of base cards, connected by a single smaller jumper card in which all ground vias are located. Each base card lies on a respective side of the axis, the jumper straddling the axis.

Abstract: A papermaking vacuum apparatus having a web-facing surface adapted to support a papermaking belt and comprising a head, a body and at least one vacuum slot disposed in the head and defining an aperture on the web-facing surface. The vacuum slot is in fluid communication with the web-facing surface and extends from the web-facing surface to the body which is in further fluid communication with a vacuum source. The web-facing surface has a textured clothing interposed between the web-facing surface of the vacuum apparatus and a backside of the papermaking belt. The textured clothing creates leakage between the backside of the papermaking belt and the web-facing surface of the vacuum apparatus and effectively eliminates the vacuum seal between these two surfaces.
