摘要： A pump comprises a diaphragm assembly which includes a first diaphragm (22) having a first diaphragm edge (28) and a second diaphragm (24) having a second diaphragm edge (30). The first diaphragm edge (28) and the second diaphragm edge (30) are bonded together so that a bellows chamber (26) is formed between the first diaphragm (22) and the second diaphragm (24). At least one and possibly both of the first diaphragm (22) and the second diaphragm (24) is a piezoelectric diaphragm which displaces in accordance with application of an electrical signal. A driver applies the electrical signal to whichever of the first diaphragm (22) and the second diaphragm (24) is the piezoelectric diaphragm. The first diaphragm and the second diaphragm bow outwardly together and shrink in diameter during a suction stroke but flatten out and increase in diameter during a pump stroke.

In some example implementations, the first piezoelectric assembly and the second piezoelectric assembly are constructed and arranged so that a temperature dependency of the first piezoelectr assembly is cancelled by the temperature dependency of the second piezoelectric assembly. In a first example embodiment, a first piezoelectric assembly comprises a first piezoelectric diaphragm connected to the actuator element for displacing the actuator element response to displacement of the first piezoelectric diaphragm. In a second example embodiment, the actuator element is at least partia situated in a housing wherein the actuator element is capable of reciprocating movement.

摘要： A diaphragm assembly (20) comprises at least two piezoelectric diaphragm members (22) arranged in a stacking direction (23). An interface layer (24) is situated between adjacent piezoelectric diaphragm members (22). The interface layer (24) in the stacking direction (23) is displaceable but incompressible. The interface layer (24) permits lateral movement of the adjacent piezoelectric diaphragm members (22) relative to the interface layer (24) in a direction perpendicular to the stacking direction (23). The interface layer (24) can comprise, for example, an incompressible liquid or a semi-liquid. A gasket (26) can be used to seal the incompressible substance in the interface layer if necessary.

摘要： A drive circuit (18) produces a drive signal having a waveform of a predetermined waveform shape for a device (10) having a piezoelectric actuator (14). The drive circuit (14) includes a memory (140) which stores waveform shape data which is utilized by the drive circuit in producing the drive signal. The drive circuit utilizes the waveform shape data so that, for each of plural points comprising a period of the waveform, the drive signal has an appropriate amplitude for the predetermined waveform shape. The waveform shape data has preferably been prepared to optimize one or more operational parameter(s) of the device. Preferably the waveform shape data has been prepared by solving a waveform equation, the waveform equation having coefficients determined to optimize at least one operational parameter of the device. The number of coefficients determined for the waveform equation depends on the number of harmonics of the waveform that are within a bandwidth of the device. Other aspects concerns devices which utilize the drive circuit, methods for operating devices, the memory (212) which is utilized by the drive circuit (e.g., the drive circuit which produces the drive signal for the device having the piezoelectric actuator) to store the waveform shape data, as well as apparatus and method for generating the optimized waveform shape data.

摘要： An electrically driven actuator (20, 120) comprises a deformable member (22, 122) which deforms as a function of applied voltage. A coupler (30) connects the deformable member to a shaft (40, 140) which, depending on embodiment and mode of operation, may be either displaceable along its axis or stationary. A controller (50, 150) actuates the deformable member by applying voltage in a manner to cause the coupler, as a function of applied voltage, either to engage or slip relative to the shaft, thereby causing relative displacement of the shaft and the deformable member. In one embodiment and mode of operation, the shaft (40) is displaceable and comprises an actuator element, whereas in another embodiment and mode of operation the deformable member ( 122) comprises the moveable actuator (121). Preferably, the controller actuates the deformable member to cause linear relative displacement of the shaft and the deformable member. In yet other embodiments and mode of operation, a deformable assembly (222) comprises a first deformable member (222A) and a second deformable member (222B), with the first deformable member (222A) being connected to a shaft (240) through a coupler (230) and the second deformable member (222B) being connected to a sleeve (270) which fits over the shaft (240) and allows relative translation of the shaft (240) and sleeve (270).
