摘要:
An apparatus and method for arbitrating bus ownership of a first communication bus ("C1-bus") for a plurality of C1-bus masters and arbitrating bus ownership of a second communication bus ("C2-bus") for a plurality of C2-bus masters. The apparatus further performs a DMA transfer, without processor assistance, between a first component coupled to the C1-bus and a second component coupled to the C2-bus.

The present invention refers to new classes of polymerisable monomers, to molecularly imprinted polymers obtainable by polymerisation of at least one of the monomers and a crosslinking monomer in the presence of a template molecule. The obtained polymers may be used for separation of enantiomers, diastereomers of the template molecule, and also for separation of the template molecule or template molecule analogues from structurally related compounds.

A method of producing a molecularly-imprinted material comprises synthesizing a peptide, oligosaccharide or oligonucleotide on a disposable surface modified support to produce a support surface-attached peptide, oligosaccharide or oligonucleotide, providing a selected monomer mixture, contacting the monomer mixture with the support surface-attached peptide, oligosaccharide or oligonucleotide, initiating polymerisation or at least one crosslinking reaction, dissolving or degrading the support surface-attached peptide, oligosaccharide or oligonucleotide and support, and obtaining molecularly imprinted material.

A vehicle dynamic-body-control actuator includes a fluid-powered-cylinder reservoir tube, a piston, a rod, and a directional lip seal. The reservoir tube has a longitudinal axis and has a first tube end attachable to one of a first vehicle component and a second vehicle component. The piston is positioned within the reservoir tube. The rod has first and second rod end portions, wherein the first rod end portion is attached to the piston and wherein the second rod end portion is attachable to the other of the first and second vehicle components. The directional lip seal surrounds at least one of the rod and the piston, extends to the reservoir tube, and is movable with the rod and the piston.

An apparatus for operating a circuit breaker. The circuit breaker includes a housing, a cradle mounted in the housing and coupled to a handle and to a movable contact. The apparatus comprises a latch frame mounted in the circuit breaker housing. A latch roller is mounted on the cradle. A latch member is configured to selectively engage the latch roller and the latch member is rotatably coupled to the latch frame. A latch shaft assembly is rotatably mounted in the latch frame and selectively engaged by the latch member. Upon rotation of the latch shaft assembly, the latch shaft assembly will disengage from the latch member and cause the movable contact to move.

A display device for large scale billboard displays comprises a set of image carriers each defining a respective sequence of image frames and each having directional properties such that different image frames are viewable from different viewing directions relative to the image carrier. A support device supports the image carriers such that they together form a composite display and an adjustment device is provided operable to adjust the orientation of the image carriers relative to the support device such that corresponding frames of each image carrier are simultaneously viewable by an observer at a predetermined position relative to the display apparatus. The image carriers may be lenticular members in which lenticular lenses overlay interdigitated strips of image elements.

A ball valve assembly for use as a control valve for controlling the flow of gas through a continuous stroke pneumatic tool. The valving element is generally spherical and non-magnetizable. The generally spherical valving element is loosely confined between two concave generally conical surfaces, which are provided on valve seat members. The concave generally conical surfaces are opposed to one another to define a valve chamber therebetween. Sufficient clearance is provided so the generally spherical valving element is free to roll and tumble as it moves in the valve chamber between the concave generally conical surfaces. This allows the ball valve assembly to be self purging of excess lubricant, dust, and the like. Wear is distributed over the entire generally spherical surface of the valving element. The loose confinement is also sufficient to provide a relatively large cross-section of gas passageway through the control valve assembly. The two valve seat members are suitably ported to permit the ball valve assembly to be used as a drop-in replacement for prior pneumatic tool control valves.

A user logic design for a mask-programmable logic device (“MPLD”) may be designed on a comparable or compatible user-programmable logic device (“UPLD”) and migrated to the MPLD, or may be designed directly on an MPLD. If the design is designed on a UPLD, the constraints of the target MPLD—i.e., differences between the devices—are taken into account so that the migration will be successful. If the design is designed directly on an MPLD, constraints of a comparable compatible UPLD are taken into account if the user indicates that the design will be migrated to the UPLD for testing. This means that when a logic design is intended to be migrated back-and-forth between a UPLD and an MPLD, only the intersection of features can be used. To facilitate migration, fixed mappings between pairs of devices may be created.
