Abstract: An infusion pump which may include a control unit and a pump engine may be used to facilitate administration of medicinal fluids to a patient. A control unit may include a motor, a controller, a housing, and a motor coupling, where the motor coupling includes two protruding motor coupling tabs extending in a direction parallel to an output shaft of the motor. A pump engine may include a housing, a rotor disposed in the housing, and a pump coupling, where the pump coupling includes at least two protruding pump coupling tabs extending in a direction parallel to an input shaft of the rotor. The controller may be configured to change an operational mode of the infusion pump, where when the infusion pump is in a positioning mode, the controller activates the motor to move the output shaft to a predetermined angular position.

Abstract: Polynucleotides and polypeptides incorporated into expression vectors have been introduced into plants and were ectopically expressed. The polypeptides of the invention have been shown to confer at least one regulatory activity and confer increased yield, greater height, greater early season growth, greater canopy coverage, greater stem diameter, greater late season vigor, increased secondary rooting, more rapid germination, greater cold tolerance, greater tolerance to water deprivation, reduced stomatal conductance, altered C/N sensing, increased low nitrogen tolerance, increased low phosphorus tolerance, or increased tolerance to hyperosmotic stress as compared to the control plant as compared to a control plant.
