20110076125	SINGLE-BRIDGE MANIPULATOR MANEUVERING SYSTEM - In one aspect, the invention is directed to a load maneuvering system that includes a pair of runway rails, a bridge that is movable on the runway rails and that includes a single bridge rail, a carriage that is movable on the single bridge rail, and a manipulator supported by the carriage. The bridge rail is configured to support the assembly of the carriage and manipulator when a load is carried by the manipulator and a resultant moment is imposed on the bridge rail. The moment may be imposed in a direction about the bridge axis, in a direction about the runway axis, or a combination of the two. By providing a single bridge rail with an enclosed member as part of (or the entirety of) the bridge rail, the overall system is lighter and requires less power for movement of the bridge on the runway rails, and requires less power to move the carriage on the bridge. Additionally, the assembly is simplified relative to some load maneuvering systems of the prior art thereby making it less expensive to manufacture.	03-31-2011

20090283490	COMPOUND-ARM MANIPULATOR - In a first aspect, the invention is directed to a manipulator that is relatively compact and has a relatively large range of motion. The manipulator includes a linkage that folds back on itself, which reduces the footprint of the linkage. In a particular embodiment, the manipulator includes a linkage and a load balancing device. The linkage includes a first link, a second link, a third link and a fourth link. The first link and second links are rotatably connected to a base about first and second connection axes. The third and fourth links are connected to the first and second links respectively about third and fourth connection axes respectively. The third and fourth links are rotatably connected to a lift arm about fifth and sixth connection axes respectively, wherein the fifth and sixth connection axes are horizontally displaced from the third and fourth connection axes in the direction of the first and second connection axes. The load balancing device is configured to support the linkage in a selected position against a load and configured to permit the load to be moved upwards or downwards with a selected amount of force on the lift arm. The manipulator may be provided as part of a load maneuvering system that further includes a transport system that may be similar to that used on an overhead crane.	11-19-2009

20090013860	PNEUMATIC MULTI-WEIGHT BALANCING DEVICE - A load balancing pneumatic manipulator comprising an inflatable reservoir for establishing via an amplifier a pressure within a lift cylinder that is sufficient to balance the weight of an object being lifted. The reservoir is inflated and deflated by inflation and deflation valves, respectively, that may be operated from an operator control center proximal an end effector of the manipulator. The valves may be actuated via pushbuttons or actuated in a mutually exclusively fashion via a neutrally biased reciprocating actuator. The manipulator advantageously allows loads of different weights to be lifted in a semi-automatic fashion with operator involvement to select the load balancing pressure. The manipulator further comprises an air release system that closes a blocking valve in the event of release of the object being lifted and optionally in the event of a loss of air supply pressure. The pressure within the lift cylinder is thereby preserved and can be vented at different rates, depending upon the condition causing closure of the blocking valve.	01-15-2009
