Abstract: A relay protection device is disclosed for use with a magnetic latching relay, the relay having two stable states. The relay comprises an electromagnetic device which under the effect of a switching impulse current, causes the relay to switch from one of the states to the other. The relay protection device comprises a current detector for connection with electrical control contacts of the relay, which measures a current induced by the switching mechanism, a comparator operable to determine if the current exceeds a predetermined threshold, and a controller for connection with the electrical control contacts and, based on the determination of the comparator, operable to apply a retention voltage across the electrical control contacts so as to cause the electromagnetic device to generate a magnetic field to retain the switching mechanism in its current state.

Abstract: A filter top assembly for a cage, wherein the assembly includes a bonnet having a perforated top wall to protect filter paper placed above the top wall. The perforations may be small enough to prevent an animal from getting a purchase position and spaced apart sufficiently to prevent the animal from biting the spacing between the perforations. The bonnet may also include one or more elevated ribs to retain the filter paper suspended above the bonnet.

Abstract: Provided are a method, system, and program for generating and indicating incremental backup copies from virtual copies of a data set. A virtual copy operation is initiated to create a virtual copy of a data set, wherein the virtual copy represents the data set at a point-in-time copy, and wherein the virtual copy is completed without transferring the data set to a backup location. An incremental backup operation is initiated with respect to an identified virtual copy, wherein the incremental backup operation copies changes to the data set that occur since a most recent creation of an incremental backup set.

Abstract: The present invention relates to a valve having a first assembly cooperating with a second assembly to create a seal, wherein the first assembly opens before the second assembly opens and closes after the second assembly closes. The invention also relates to a valve wherein the pressure required to open the second assembly is greater than the pressure required to open the first assembly.

Abstract: A tamper respondent system having: a physical volume containing an electronic device to be protected; an at least partially conductive surface proximate to the electronic device; and a tamper respondent sensor over the electronic device (the sensor comprising: a flexible, dielectric substrate; conductive traces on the substrate; a porous insulating layer having pores over the conductive traces; and adhesive within said pores of said porous insulating layer), wherein the adhesive is in contact with both the substrate and the at least partially conductive surface through the porous insulating layer.

Abstract: Embodiments of a rack assembly for housing cages comprise at least one shelf, the shelf having a shelf section comprising a runner capable of being positioned in a least a first position and a second position. The shelf section is constructed and arranged to accommodate two cages having a first and second widths when the runner is positioned in the first position. The shelf section is constructed and arranged to accommodate a single cage having a third width when the runner is in a second position, the first and second widths being less than the third width.

Abstract: A docking assembly for a ventilated cage and rack system that can facilitate installation and reduce leakage of air is provided. The docking assembly is connectable to air plena of the rack system and includes a cup, and a tubular body having a docking base. The tubular body is constructed and arranged to be slideably displaceable between the cup and the docking base when the tubular body is aligned coaxially with the cup and docking base. A spring may also be provided outside and surrounding the tubular body. The tubular body includes a plurality of displaceable legs. The legs are preferably urged outward in the absence of pressure and may be displaced inward, toward each other, for insertion into a docking aperture of a plenum. Once inserted, the legs return to their normal, non-displaced position to secure the docking assembly to the plenum.

Abstract: A locking assembly for securing and retaining a cage to a rack. The locking assembly is supported by a rack and includes a lock member. The lock member includes an obstruction member. The lock member is movable from an unlocked position to a locked position, wherein the default position of the lock member is the locked position. The lock member is designed and constructed such that the insertion of a person's hand into the hand space between the lock member and a cage is sufficient to cause the lock member to pivot into the unlocked position and move the obstruction member so that the cage can be removed from the rack.

Abstract: A fluid delivery adapter for use with a wire bar lid is provided.
