Abstract: A cleaning device is provided for removing debris from rotating conveyor rollers, and includes a housing constructed and arranged for insertion between two adjacent rotating rollers, the housing having a first set of cleaning wheels at a first housing end associated with a first of the conveyor rollers, and a second set of cleaning wheels located on an opposite end of the housing and associated with a second of the conveyor rollers. At least one of the cleaning wheels is reciprocable relative to the housing between a retracted position permitting insertion of the housing between the rollers, and a extended position extending the reciprocating wheel towards the adjacent roller for limiting lateral movement of the housing between the rollers. Upon movement of the housing between the rollers in a direction parallel to a longitudinal axis of the rollers, the cleaning wheels operationally engage and remove residue collected on the rollers.

Abstract: Provided, in one embodiment, is a fuel cell interconnect comprising: a first primary conduit located at the periphery of the interconnect; a second primary conduit located at the periphery of the interconnect; a fuel cell distribution plate located at the top or bottom of the interconnect adapted to interface with a fuel cell and comprising: (i) an internal distribution conduit through the fuel cell distribution plate, and (ii) two or more second distribution conduits through the fuel cell distribution plate located peripheral to the internal distribution conduit but interior to the primary conduits, the internal and second distribution conduits adapted to convey fluid from one to the other along the top or bottom, as relevant, of the interconnect; and one or more manifold plates comprising a conduit from the first primary conduit to the internal distribution conduit and a conduit from the second primary conduit to two or more said second distribution conduits.

Abstract: Systems and methods enable numerically creating a flat field in a compact radar range with a curved reflector, and without use of a separate phased array of elements, at frequencies lower than those that are possible with currently known, reflector-only compact radar ranges. A compact radar range is calibrated to enable weighting factors to be computed. The weighting factors may be computed by performing an optimization algorithm. The weighting factors are used to weight separate target signals sequentially returned from a target zone such that, when combined, a numerically composite measurement has a substantially constant magnitude across the target zone.

Abstract: A method and apparatus are provided for imaging a narrow body lumen, the method comprising maintaining separation between a distal end of an optical viewing scope and a lumen wall with a spacing structure which extends distally from the distal end of an access catheter. Optional spacing structures include distal cages and a guidewire which is fixed to and extends distally from the access catheter body. The invention is beneficial during either retrograde imaging of the fallopian tube, and also allows antigrade imaging and advancing the access catheter and scope under the direction of the image provided, as it prevents the tubal wall from coming into such close proximity to a falloposcope as to produce “white-out” on the imaging monitor.
