Abstract: The disclosure generally describes fluid delivery devices that include both active and passive fluid delivery. In one example, a therapeutic fluid delivery device includes a first reservoir configured to house a first therapeutic fluid and a second reservoir configured to house a second therapeutic fluid. The first reservoir is configured to passively transfer the first therapeutic fluid to a patient. In addition, the therapeutic fluid delivery device includes a fluid delivery pump configured to actively transfer the second therapeutic fluid from the second reservoir to the patient.

Abstract: A system employing multiple implantable therapy delivery devices may be configured to provide coordinated or synchronized therapy by allowing the devices to communicate with each other, directly or indirectly. Fault tolerance or redundancy may be incorporated into the system to allow for correction of failed devices in real time or pseudo real time.

Abstract: A standoff arm and probe assembly for a helicopter has a standoff mounting arm that extends outwardly from the helicopter body in a selected direction, preferably forwardly. The standoff arm has an outer end that mounts a low lateral speed sensing probe that is positioned with an axis substantially parallel to the axis of a helicopter rotor, and within the downwash region of air movement causes by the rotor. The low lateral speed sensing probe has ports that are arranged annularly around the probe, and the pressures sensed at selected annular or peripheral locations on the probe are measured to determine low air speeds. Additionally, the standoff arm can mount a plurality of other sensors such as a pitot pressure probe extending forwardly from the arm, a lateral pressure sensing probe along a lateral side of the arm, and the arm can mount outside air temperature sensors, ice detectors, and total air temperature sensors, if desired.
