摘要： A single piezoelectric is excited at a first frequency to cause two vibration modes in a resonator producing a first elliptical motion in a first direction at a selected contacting portion of the resonator that is placed in frictional engagement with a driven element to move the driven element in a first direction. A second frequency excites the same piezoelectric to cause two vibration modes of the resonator producing a second elliptical motion in a second direction at the selected contacting portion to move the driven element in a second direction. The piezoelectric is preloaded in compression by the resonator. Walls of the resonator are stressed past their yield point to maintain the preload. Specially shaped ends on the piezoelectric help preloading. The piezoelectric can send or receive vibratory signals through the driven element to or from sensors to determine the position of the driven element relative to the piezoelectric element or resonator. Conversely, the piezoelectric element can receive vibration or electrical signals passed through the driven element to determine the position of the driven element. The resonator is resiliently urged against the driven element, or vice versa. Plural resonators can drive common driven elements.

摘要： The invention relates to a piezoelectric motor comprising a piezoelectric component that is connected to a resonator and a two-dimensional resonator that interacts with a movable. element, the resonator having principal surfaces that are parallel to each other and that are also identical in shape and size. The invention further relates to methods for producing such piezoelectric motors, wherein the resonators are manufactured by cutting a profiled, extruded bar into lengths or by cutting, preferably by punching, from sheet metal having constant thickness. Finally, this invention relates to a method for exciting such a piezoelectric motor, wherein the excitation frequency or frequencies is/are generated by the control electronics as a function of time in response to the respective peak current and/or in response to the respective phase minimum between current and voltage and/or in response to the change in phase.

摘要： The present invention relates to an apparatus and method for the generation of directed vapor from a liquid source. Vaporization takes place within a device capable of confining boiling to a geometrically small volume, and expelling it as heated vapor via capillary vaporization. The foregoing is accomplished through the use of a lightweight, compact and portable personal vaporization device that generates heated vapor by the flash boiling of small volumes of aqueous liquid in a safe and energy-efficient manner. Further, the production of vapor absent microbes in aqueous systems is accomplished through the combination of microporous componentry and flash vaporization. The apparatus and methods are directed toward personal humidification for comfort and therapeutic purposes in the case of aqueous liquids, but may also be used with other, non-aqueous liquids.

摘要： The present invention concerns capillary force vaporizers for use in vaporizing liquids and emitting pressurized vapors. In one embodiment, the inventive capillary force vaporizer includes a porous member, a heater component to convey heat to the porous member, and a vapor containment region. The porous member further includes a capillary network, a surface for receiving liquid and a vaporization area in which vapor is produced from the liquid. The vapor is collected and pressurized within the vapor containment region, which includes one or more openings for the release of vapor at a velocity greater than zero. Several different embodiments for capillary force vaporizers and systems comprising capillary force vaporizers are disclosed along with methods for their use.
