摘要:
A speaker system for reproducing low frequency sound includes a plurality of substantially rigid panels driven in unison via a mechanical linkage to a common high speed servomotor. The motor is driven by a separate amplifier together with negative feedback from motion of the panels to enhance accurate reproduction of sound.

A microelectromechanical structure, comprises a first element that includes a first element surface, and a second element that includes a second element surface, and an element gap between the first element surface and the second element surface. At least one of the first element and the second element is mobile. One of the first and second element surfaces includes a convex contact surface and the other one of the first and second element surfaces includes a concave contact surface.

An apparatus and method for optimizing a parametric emitter system having a pot core inductive device coupled between an amplifier and emitter. The pot core inductive device allows for adjustments of the air gap formed between the two halves of the pot core structure to adjust its inductive value. This post-manufacture adjustability allows for corrections of differences caused by operations of other components in the audio system and to account for slight differences in the electrical circuit of different amplifier/emitter combinations. As efficiency of the system is dependent on the functional relationship between the amplifier, inductive device, and emitter, this allows for fine tuning of the signal to obtain high quality.

摘要:
A system for enhancing the separation of particles or fluids from water is disclosed. A settling tank or skim tank is provided with an open submersible acoustophoretic separator. In a skim tank, the separator captures and holds oil droplets or particles, permitting them to coalesce until they are large enough and have sufficient buoyant force to float to the top of the tank. In a settling or sediment tank, separator captures and holds particles until they are large enough that the force of gravity causes them to settle out of the water. The acoustophoretic device thus speeds up separation of the particles or droplets from the water.
摘要:
The present PCT application relates to harmful electromagnetic waves, in particular electromagnetic waves that are harmful for optical articles that are passed through by or that emit light such as visual media where a type of impairment, image and color processing distortions, and impaired optical information are observed where the sound or electromagnetic radiation modifies the images or colors conveyed. The eCRT devices correct all these interferences via a looping of the electronic information which stabilizes the electron flows. The materials in the path of the light rays are not amorphous, they react during the passage of the light rays generating distortions. Optical transparency does certainly not rule out the stresses undergone by the electrons to which the structures that convey the electromagnetic energies of all types of frequencies are subjected. Molding and polishing operations excite the electrostatic charges generated by the friction of the polishing itself at the surface or internally. Sound radiation also excites silica-based structures which are agitated, which impairs the transparency and performances thereof. Devices according to all the claims can be used for safety and comfort, devices relating to optical articles, terrestrial or onboard lighting systems, all glazing units in housing, technical glazing units that may or may not be transparent, for example for the use of infrared rays or other rays for ballistics, and uses for the transport and production of information, generally audiovisual information, and telescopes for astronomy.
摘要:
The invention relates to an eCRT electronic component that belongs to a new generation due to the high resolution thereof for sensing electromagnetic information, and that makes it possible to process the generation of self-induced currents of a mechanical pr electromagnetic nature. Knowing that a wheel rolling on the aluminium or metal rim thereof and on the spokes thereof is considered as a Barlow wheel or a Telma, the electronic functions for managing the self-control of the vibrations are made possible as they are all based on the electronic structure that is subjected to and stressed by the mechanical stresses, and all the structures are concerned, whether chemical, mechanical, fluid or gaseous. In a wheel, an axle or a tyre, all these electromagnetic applications are concerned. All the technical fields in dynamic phase, by the single structure of matter comprised of electrons. The functions are the use of the control of the mechanical vibratory and electronic undulating performances, and relate to the use of mechanics, solids, fluids and gases. Nanotechnology gives rise to a new relation in terms of information and electronic management without electric wires, thereby unifying the different sciences of solid, liquid and gas mechanics, and active electricity in dynamic phase. It can be said that the inner particularity of each "proper-reactivity" part erased for the benefit of a single "global-reactivity" function unifying the single quality of the requested function. The eCRT probes unify and concentrate forces into a single action polarity and provide each part with the correct behaviour information.
