A piezoelectric micropump is disclosed for pumping fluid from a container to a delivery point in low volumes and at controlled flow rates. The pumping action is created by movement of two or three diaphragms. The movement of each diaphragm is caused by expansion and contraction of an attached piezoelectric actuator. Coordination of the movement of the diaphragms creates unidirectional flow of the fluid. The piezoelectric actuators are cantilevered between the pump body and the diaphragms to provide greater deflection of the diaphragms. The piezoelectric actuators preferably are piezoelectric bimorphs such that the diaphragms can function as both seals and pumps.

A preferred embodiment of the invention includes a control system (and corresponding method) which monitors and controls both joint torque and arm position during operation of a device such as a manipulator, whereby oscillation is rapidly removed when the system is disturbed by either movement, stopping of the system after completing a movement, by disturbance from external forces, or any other disturbance. Furthermore, the system can achieve rapid motion over a wide manipulator payload range. This is achieved in a preferred embodiment by providing control of torque and thereby allowing control of the arm deflection. In this illustrative arrangement, the joint torque takes on high levels (below the arms elastic limit), allowing rapid motion without causing arm oscillation. It has been found that the arm can be transformed from a cantilever-type structure to a pin-free-type structure. The invention allows for high joint torque levels with low frequency content, thereby enabling rapid arm movement without induced oscillation.

An apparatus for the detection of extravasation in an imaging procedure includes at least a first source of energy to supply imaging energy to tissue in the vicinity of a site and at least a first sensor to measure a signal resulting from the energy supplied to the tissue by the first imaging energy source. In preferred embodiment, the energy may be one of X-ray, gamma ray or ultrasound energy.

A protection circuit, configured to detect and suppress electrical pre-arcing and arcing conditions in a resistive heater wire circuit, comprises a transient voltage suppressor, signal level sensing load coupled to the output of the voltage suppressor, detection and control circuitry, and a high-speed switch or electrical gate. The control circuitry is configured to control the operation of the switch, coupled between said control circuitry and the heater wire, wherein the switch is opened in response to an electrical pre-arcing or arcing condition or a short circuit condition.

A method is disclosed for determining the operating condition of a medical pump based on data derived from a pressure sensor and a position sensor. The pressure sensor generates pressure data by sensing the force on the pumping element. The position sensor generates position data by tracking the pumping cycle and determining the position of the pumping element. The pump pressure data and pump position data are processed and the calculated results compared with a pre-determined threshold value to determine the operating condition of the pump. The three main types of operating conditions of concern are the following: normal condition, where liquid is present and no leaks exist in pumping chamber; leak condition, where liquid is present but a leak exists in the pumping chamber; and air stroke condition, where the chamber contains some air.

A method of detecting a change (that is, an increase or a decrease) in the level of fluid in tissue in a first area of a body includes the steps of: applying electromagnetic energy, preferably in the frequency range of approximately 300 MHz to approximately 30 GHz, to a first volume of the body; measuring a resultant or returned signal; comparing the signal to a reference signal to determine if the fluid level in the tissue has changed. In one embodiment, the method detects changes in the level of fluid in tissue of a body by applying electromagnetic energy to a first volume of the body over a period of time (for example, using an antenna or antennae); measuring a resultant signal or a signal returned from the tissue; and comparing the signal to a reference signal to determine if a level of fluid in the tissue has changed during the period of time.

Tissue sensors house one or more sensor elements. Each element has a housing mounted substrate and a superstrate with a planar antenna between. A transitional periphery (TP) of a superstrate outer surface interconnects a base to a plateau. At least some of the TP has a generally smooth transition. Plural elements are spaced by the housing. Alternately, the superstrate TP is flat, the housing extends to the outer superstrate surface and a shield surrounds the element. The housing is flush with or recessed below the superstrate and defines a TP between the housing and superstrate. A method converts a reference signal to complex form; plots it in a complex plane as a reference point (RP); converts a measurement signal to complex form; plots it in the complex plane as a measurement point (MP); determine a complex distance between the MP and the RP; and compares complex distance to a threshold.
