    Abstract: A fluid infusion pump includes a disposable cassette having an inlet, an outlet, and a fluid chamber between the inlet and the outlet. There is a fixed wall of the fluid chamber and a movable wall of the fluid chamber. A pump body receives the cassette in a fixed operating relationship such that an actuator in the pump body is activatable for reciprocal advancement and retraction with respect to the cassette and is adapted to confront the movable diaphragm when the cassette is received in the pump body. There is a detachable coupling between the actuator mounted in the pump body and the movable wall so that fluid is expelled from the fluid chamber on advancement of the actuator and positively drawn into the fluid chamber upon retraction of the actuator.

    Abstract: A piezoelectric microblower includes a vibrating plate including a piezoelectric element and arranged to be driven in a bending mode by applying a voltage of a predetermined frequency to the piezoelectric element, and a blower body arranged to fix both ends or a periphery of the vibrating plate and to define a blower chamber between the blower body and the vibrating plate, an opening being provided in a portion of the blower body facing a central portion of the vibrating plate. In a portion of the blower chamber corresponding to the central portion of the vibrating plate, a partition is provided around the opening and a resonance space is defined inside of the partition. A size of the resonance space is set such that a driving frequency of the vibrating plate and a Helmholtz resonance frequency of the resonance space correspond to each other.

    Abstract: A marine steering system operable in either power steering or manual hydraulic modes. The system employs a modified helm pump having a single rotatable input shaft connectable to a steering wheel and dual hydraulic and electronic output. An encoder, such as an optical incremental encoder or hall effect device, is mechanically coupled to the input shaft for generating an electronic steering control signal representative of the change in position of the steering wheel. In the power steering mode, the electronic steering signal is processed by an amplifier controlling the operation of an auxiliary pumpset connected to the rudder steering cylinder. A bypass manifold disposed between the helm pump and the steering cylinder disables the hydraulic steering system in the power steering mode. In the event of power failure, the bypass manifold valves are opened and the system automatically switches to manual hydraulic steering.

    Abstract: A method and apparatus for preventing accidental manual rotor reversal in a peristaltic pump is provided. A peristaltic pump may be provided with a hand crank or the like to drive a rotor assembly of the pump manually in the event of failure of the electric motor drive of the pump. An indicator may provide information to the pump operator to inform the operator of the direction in which the pump was rotating when last driven by the electric motor. Further an alarm device may alert the operator when the operator is attempting to rotate the pump in the direction opposite the direction in which the pump was rotating when last driven by the electric motor or the direction last selected by the operator before loss of power.
