A method for transforming an audio signal and a system employing that method is disclosed. The method proceeds by extracting from the signal components that fall within a stop band, for example, using one or more low-pass filters. Then, a set of one or more harmonics of the extracted components is generated by down-sampling to create an intermediate signal, which is then repeated. Each harmonic is then weighted by controlling its gain by application to it of a respective weighting factor, the factors being determined by the psychoacoustic properties of a system that will reproduce the signal. Then, the weighted harmonics are added to the audio signal (which may have been subject to a delay to ensure synchronization) to create an output signal.

Audio enhancement method and system

A transducer array comprises a conductive back plate, a conductive front platehaving openings, and a plurality of piezoelectric vibrator elementslocated in an array between the plates. The vibrator elementsare two-layer elements which each include a metal portionand a PZT element. These elementsare in electrical contact with the respective plates. The vibrator elementsare attached to support elementsupstanding as part of the back plate. The transducer array can be formed as a batch process in which the vibrator elementsare formed simultaneously, and then simultaneously attached to the support elements

Ultrasonic transducer array and a method for making a transducer array

A method of producing hard disk drives of reduced size including using a one or more MEMS spindle motors, and one or more magnetic heads. Each spindle motor includes a rotor and a stator. The rotor carries a film of magnetic film, and a head is arranged to communicate data with the magnetic film. The rotors are formed by MEMS technology. Rotor elements are formed within a substrate, and the substrate is subsequently cut to simulate the rotor elements, and turn them into rotors.

Method of producing hard disk drives of reduced size

A micro-rotating device has a rotor(of diameter not more than 1.5 cm), a shaftthreaded through the rotor, and a shaft holderfor holding the shaft. The shaft holders are formed by etching an Si substrateto form multiple shaft receiving openings. The rotors and shafts too are formed from respective Si substrates. The rotorsare located over the shaft holders, and the shafts threaded through the rotorsinto the openingsand attached there by a wafer bonding process. Then the substrateis partitioned to give individual motor elements. Protrusionsextend from the rotor in the direction towards the stator to space the rotor from the shaft holder.

Method of forming a micro-rotating device, and a micro-rotating device produced by the method

A MEMS (micro-electromechanical system) device having a rotor, a statorand a shaftconnected to the statorand around which the rotorrotates. Groovesare formed in a portion of the rotor, such that when the rotorrotates an air bearing is formed for supporting the rotorand maintaining its distance from the shaftand stator. The rotoris formed from joining two substrates. One of the substratesincludes a surface having openingsincluding frustoconical walls, and one of the substratesincludes a surface having openingsincluding walls perpendicular to the surface of the substrate. The openings in the two substrates are in register with each other so that pairs of the openings form chambers. Each chamberis provided with a shaft, which is positioned with a wide section of the shaft trapped in the chamber. The wide section of the shaft has a frustoconical surface facing the frustoconical walls of the chamber
