摘要： A waveguide system for radiating sound waves. The system includes a low loss waveguide for transmitting sound waves, having walls are tapered so that said cross-sectional area of the exit end is less than the cross-sectional area of the inlet end. In a second aspect of the invention, a waveguide for radiating sound waves, has segments of length approximately equal to A ⁡ ( y ) = A inlet ⁡ [ 1 - 2 ⁢ Y B + ( y B ) 2 ] where l is the effective length of said waveguide and n is a positive integer. The product of a first set of alternating segments is greater than the product of a second set of alternating segments, in one embodiment, by a factor of three. In a third aspect of the invention, the first two aspects are combined.

摘要： An electromagnetic actuator includes a stator assembly mounted to a center pole formed of material having high magnetic permeability and functions as a return path for the magnetic field generated when current is passed through coils in the stator assembly. When current is applied to one or more coils within the stator assembly, a magnetic field is generated that interacts with a magnetic field generated by one or more magnets disposed within the armature assembly and causes the armature to move relative to the center pole thus, for example, opening or closing a valve.
摘要翻译：电磁致动器包括安装到由具有高磁导率的材料形成的中心极的定子组件，并且用作当电流通过定子组件中的线圈时产生的磁场的返回路径。当电流施加到定子组件内的一个或多个线圈时，产生磁场，其与设置在电枢组件内的一个或多个磁体产生的磁场相互作用，并使电枢相对于中心磁极移动，因此，为例如，打开或关闭阀门。
