  • Publication number: 20130104387
    Abstract: A method which relates to fabricating a dielectric waveguide (WG) on a PCB for RF communication between ICs on the PCB. The WG can replace a baseband copper bus and resulting in the PCB being smaller and/or cheaper. The WG may be printed, stamped, cut or prefabricated onto the PCB.

  • Publication number: 20130049883
    Abstract: Conventional technologies using copper tracks to couple integrated circuits (ICs) disposed on printed circuit boards (PCBs) face limitations in scaling beyond a certain transmission rate, restricting their future applications. Described herein is a waveguide network, in which the network comprises ICs on a PCB coupled via a dielectric waveguide, which advantageously overcomes these limitations. The dielectric waveguide is able to transmit radio frequency (RF) signals and has a bandwidth of at least 100 GHz, among other features. Further, the network can be arranged with different topologies such as ring, star or bus based, and is also couplable to other equivalent networks on the PCB using suitable waveguide-based networking devices.

  • Patent number: 8229135
    Abstract: 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.

  • Patent number: 7732987
    Abstract: A transducer array comprises a conductive back plate 32, a conductive front plate 33 having openings 62, and a plurality of piezoelectric vibrator elements 31 located in an array between the plates. The vibrator elements 31 are two-layer elements which each include a metal portion 311 and a PZT element 312. These elements 311, 312 are in electrical contact with the respective plates. The vibrator elements 31 are attached to support elements 51 upstanding as part of the back plate 32. The transducer array can be formed as a batch process in which the vibrator elements 31 are formed simultaneously, and then simultaneously attached to the support elements 51.

  • Patent number: 7480981
    Abstract: 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 4, and the substrate is subsequently cut to simulate the rotor elements, and turn them into rotors.

  • Patent number: 7239054
    Abstract: A micro-rotating device has a rotor 200 (of diameter not more than 1.5 cm), a shaft 202 threaded through the rotor 200, and a shaft holder 207 for holding the shaft. The shaft holders are formed by etching an Si substrate 501 to form multiple shaft receiving openings 508. The rotors and shafts too are formed from respective Si substrates 301, 401. The rotors 200 are located over the shaft holders 207, and the shafts threaded through the rotors 200 into the openings 509 and attached there by a wafer bonding process. Then the substrate 501 is partitioned to give individual motor elements. Protrusions 206 extend from the rotor in the direction towards the stator to space the rotor from the shaft holder.

  • Patent number: 7088019
    Abstract: A MEMS (micro-electromechanical system) device having a rotor 44, a stator 43 and a shaft 27 connected to the stator 43 and around which the rotor 44 rotates. Grooves 47 are formed in a portion of the rotor 44, such that when the rotor 44 rotates an air bearing is formed for supporting the rotor 44 and maintaining its distance from the shaft 27 and stator 43. The rotor 44 is formed from joining two substrates 13, 23. One of the substrates 13 includes a surface having openings 7 including frustoconical walls, and one of the substrates 23 includes a surface having openings 15 including 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 24. Each chamber 24 is provided with a shaft 27, which is positioned with a wide section of the shaft trapped in the chamber 24. The wide section of the shaft has a frustoconical surface facing the frustoconical walls of the chamber 24.
