Abstract: Integrated table motion includes a computer-assisted device. The computer-assisted device includes articulating means; means for receiving, via a means for communicatively coupling the computer-assisted device with a table means, a table movement request from a table command means, the table means being separate from the computer-assisted device; means for determining whether the table movement request should be allowed; and means for allowing the table means to perform the table movement request based on determining that the table movement request should be allowed.

Abstract: A robotic system comprises an input device movable by an operator and a processing unit. An operator reference frame is defined relative to the operator. The processing unit is configured to present, to the operator, a first image of a first tool captured by an imaging device, receive, from the operator, a first indication that a first axis of the input device is aligned with a corresponding axis of the first tool in the first image, and in response to the first indication, determine a first alignment relationship between the imaging device and the first tool based on a second alignment relationship between the operator reference frame and the input device.

Abstract: A packaged fuel unit and a refillable hydrogen generator that uses the fuel unit to produce hydrogen gas are disclosed. The fuel unit includes a reactant that can undergo a thermal decomposition reaction that produces hydrogen gas when heated to at least a minimum initiation temperature. The reactant is contained within a package that includes a poor thermal conductor with one or more thermal conductor sections for conducting heat from outside the package to the reactant. The hydrogen generator includes a holder with a cavity in which the fuel unit can be removably disposed and a heating system for heating the fuel unit when disposed therein. The hydrogen generator can be part of a fuel cell system including a fuel cell battery that is provided with hydrogen gas from the hydrogen generator.

Abstract: A heater assembly for use in a hydrogen generator can be retracted to facilitate insertion and removal of a replaceable fuel unit without damaging the heater assembly or the fuel unit and extended to provide good thermal contact with the fuel unit during use of the hydrogen generator. The heater assembly includes a support member, a heater, and an actuator for extending and retracting the heater assembly. When the heater is energized it heats the actuator, thereby extending the heater assembly to contact the adjacent fuel unit, and when the heater is deenergized the actuator cools to retract the heater assembly and provide a gap between the heater assembly and the adjacent fuel unit. The actuator is movably secured to the heater or the support member by a retainer such that an end of the actuator is movable within the retainer as the actuator changes shape during heating and cooling.

Abstract: A regulator is provided for supplying fluid, e.g., air, to a fluid consuming battery. The regulator includes a valve housing adapted to be in fluid communication with a fluid consuming electrode of a fluid consuming battery cell. The valve housing has an opening. The regulator also includes a valve member disposed in the opening of the housing and configured to move axial relative to the housing between an open valve position and a closed valve position, wherein fluid is able to pass to the fluid consuming electrode in the open valve position.

Abstract: An improved method of detecting, in a beta.sub.2 m containing clinical sample, a virus of the herpes group or an antibody to that virus, by assaying the sample with a reagent that will reveal the presence of the virus or antibody comprising, utilizing or removing the beta.sub.2 m prior to the assay by(1) removing beta.sub.2 m from at least the sample and reagent, or(2) contacting a sample that is to be assayed for virus with a reagent that reacts with beta.sub.2 m and which will form an anti-beta.sub.2 m/beta.sub.2 m/virus conjugate.
