Abstract: The present invention is directed to a fluid resistant structure to be incorporated with conventional fastening systems such as slide fasteners. Two sheaths are attached or incorporated into a closable structure, in overlapping fashion, at or near the opening of the structure. Each sheath has associated therewith a semi-rigid bead portion at its mesial portion. The length of the bead portions is generally longer than the chord length of the opening so that a slight, to pronounced, arch or bow of the beads is formed. When the structure is closed, one bead is manipulated over and laterally adjacent to the other bead, thereby forming a lateral compression abutment between the two beads. The lateral abutment is maintained due in part to the arch or bow formed by the difference between the bead length versus the chord length.

Abstract: Improved methods and apparatus are disclosed for remapping Asynchronous Transfer Mode ("ATM") cells in an ATM switch to convert a single Virtual Path Identifier ("VPI")/Virtual Connection Identifier ("VCI") address pair to multiple outgoing VPI/VCI pairs for multicast transmission. An incoming cell is examined to determine the ports through which the cell will exit and a local header is generated which includes a field specifying the I/O modules ("IOMs") through which the cell will exit. The VPI/VCI pair of an incoming multicast cell is mapped to a global multicast identifier ("MID") which is written into the local header. The cell, including the local header is then forwarded to the IOMs specified in the header. A first lookup table on each IOM is employed to provide a port bitmask indexed by MID to direct the cell to the previously identified ports, and to map the MID into a connection identifier ("CID").

Abstract: A membrane probing assembly includes a support element having an incompressible forward support tiltably coupled to a rearward base and a membrane assembly, formed of polyimide layers, with its central region interconnected to the support by an elastomeric layer. Flexible traces form data/signal lines to contacts on the central region. Each contact comprises a rigid beam and a bump located in off-centered location on the beam, which bump includes a contacting portion. After initial touchdown of these contacting portions, further overtravel of the pads causes each beam to independently tilt locally so that different portions of each beam move different distances relative to the support thus driving each contact into lateral scrubbing movement across the pad thereby clearing away oxide buildup. The elastomeric member backed by the incompressible support ensures sufficient scrub pressure and reliable tilt recovery of each contact without mechanical straining of the beam.

Abstract: A casting device 10 for positioning and supporting legs L and other lower extremities of a patient P is provided. The casting device 10 includes a center frame rail 20 which adjustably supports a series of components thereon. A gluteal support section 40 is adjustably connected to the center frame rail 20 through a slit 30. A sub-perineal spacer 50 having a desired minimum width for spacing between legs L of the patient P is slidably supported along the slit 30 of the center frame rail 20. A knee support section 70 is also slidably supported by the slit 30 of the center frame rail 20. A stance width section 90 is adjustably attached to the center frame rail 20 and supports foot positioning supports 100 extending upward therefrom. Each foot positioning support 100 is adjustable to modify a stance width W of the casting device 10.

Abstract: A method and apparatus are disclosed for multicasting through a single physical port in a switch, i.e., logical multicasting. An incoming cell is logically multicast by providing a first copy of the cell to the desired output port and providing a second copy of the cell to a loop-back element which includes standard input and output ports dedicated to loop-back operation. The cell provided to the loop-back element is subsequently provided to the desired output port such that the first and second copies of the cell are serially transmitted from the single desired output port. Further, the cell provided to the loop-back element may be repeatedly copied, provided to the loop-back element, and provided to the desired output port. Thus, the incoming cell may be transmitted through a single output port as many times as is desired.

Abstract: A fork for a fork lift truck is attached to the typical mast mounted carriage by means of upper and lower hangers. Lateral adjustment of the position of the fork relative to the carriage involves engagement and release of a pin structure carried by the upper hanger. The upper hanger incorporates a pin which is vertically movable between a first position in which the pin engages slots in the upper mounting bar of the carriage and a second position in which the pin is recessed permitting lateral, relative movement between the fork and the carriage. A spring urges the pin to the first position where the pin engages slots in then carriage mounting bar. By lifting and turning the pin can be held in a second position so that the fork is slidable laterally along the carriage mounting bar.

Abstract: A dash mat assembly (10) for installation in a vehicle includes an acoustic barrier layer (12) attached to an absorber layer (14). The acoustic barrier layer (12) is formed of relatively stiff material while the absorber layer (14) is formed of relatively flexible material. The inner surface of the acoustic, barrier layer (12) is in direct contact with the outer surface of the absorber layer. Fasteners (16) are provided for attaching the layers together. Each fastener has an elongate pin (22) with opposite ends and a flexible holding flange (24, 26) integrally molded at each end of the pin (22). The flanges (24, 26) normally extend generally transverse to a central axis of the pin and the length of each flange is greater than a cross-sectional dimension of the pin. The fasteners (16) extend completely through the acoustic barrier layer (12) and can, extend either partially or completely through the absorber layer (14).

Abstract: An acoustical barrier (10) for a vehicle having a barrier wall which includes a floor area (23) and a fire wall area (25) extending between a wheel well area (41) and a drive train area (42). The acoustical barrier (10) includes a mass layer (12) that covers at least a portion of the barrier wall. The mass layer (12) has an inner surface (16) that faces the barrier wall with an integrally formed peripheral rib (52) projecting therefrom. A first set of elongate ribs (48) intersects and joins with a second set of elongate ribs (50). The first and second sets of elongate ribs (48, 50) are located within the enclosed area. Each elongate rib (48, 50) includes an upper portion integrally formed with the inner surface (16) of the mass layer and a lower portion with an outer edge (54, 60) adapted to at least face the barrier wall.

Abstract: An interconnect assembly for evaluating a probe measurement network includes a base, respective first, second and third device-probing areas arranged on an upper face of the base in spaced-apart relation so that first, second and third device-probing ends belonging to the measurement network can be simultaneously placed on these respective areas, a reference junction, and a high frequency transmission structure connecting the probing areas and the reference junction so that high-frequency signals can be uniformly transferred therebetween despite variable positioning of the device-probing ends on the probing areas. Because the transmission structure uniformly transfers signals despite variable positioning of the device-probing ends, the measurement network can be accurately calibrated with reference, in particular, to the device-probing ends of the network by a reference unit connected to the reference junction.

Abstract: A mold for molding thermoplastic parts having a plurality of pinholes wherein at least one of the mold cavities has a number of projections in the form of three-dimensional tapering shapes, for example, cones, which extend to a point near to but spaced from the confronting surface of the other mold half cavity. The taper of the angle of the projection and spacing between the apices of the projection and the surface of the other mold half are selected so that molten thermoplastic freezes before it covers the apices of the projections during the molding process to thereby form pinholes in the resulting plastic part. A method for molding plastic parts with pinholes with the use of the mold cavity with multiple projections is also disclosed.

Abstract: A dispenser for dispensing individual pre-formed bags from a stack of pre-formed bags has a body part and an anchor part for the stack of bags. The anchor part includes a catch means for engaging the stack, whereby the stack of bags depends from the catch means, and may be grasped for removal. A stack restraining member bears against the stack to restrain the stack of bags, but can be deflected against a gravitational restoring force when one side of the first bag of the stack is drawn past it to open the first bag for loading prior to removal from the stack.

Abstract: A barrier wall (24) separating a passenger compartment from an engine compartment of a motor vehicle has an acoustical barrier assembly (102) mounted thereto.

The acoustical barrier assembly (10) includes a sound barrier layer (12) of a molded construction and sound dampening characteristics. At least one fastener (28) is integrally molded as a single piece with the sound barrier layer (12). The fastener (28) includes a plurality of outer spacer ribs (30) that project laterally from a tube (32) and space an inner surface (24) of the sound barrier layer (12) away from the barrier wall (20). A circumferentially extending flange head (34) is integral with the tube (32) and includes a first frusto-conical section (36) and a second inverse frusto-conical section (38).

Abstract: Prioritized subclasses of cells within at least one quality of service (QoS) level in an asynchronous transfer mode (ATM) network element are described. Corresponding QoS queues are provided with one or more thresholds for intelligent discard of incoming cells within a QoS, based upon cell priority, at the onset of queue congestion. Cells having a first priority within a QoS are discarded as a first queue threshold is achieved; cells having a higher priority are enqueued. A cell loss priority (CLP) bit is employed to provide a further degree of cell discard prioritization. Different traffic streams within a single queue have different priorities, enabling intelligent discard of lower priority traffic prior to complete queue congestion.
