  • Patent number: 8401469
    Abstract: Embodiments described herein include a computing device that is capable of inductive signal transfer with other computing devices. Such computing devices are provided a shield that protects the device and other components from electromagnetic interference and unwanted electrical affects resulting from the inductive signal transfer.
    Type: Grant

  • Publication number: 20110037321
    Abstract: An inductive signal interface comprises a coil assembly including one or more inductive coils, a bridge circuit including a plurality of switches, and control circuitry. The control circuitry is configured to individually operate the plurality of switches to enable the inductive signal interface to dynamically switch between a power-transmit mode and a power receive mode.

  • Patent number: 7889477
    Abstract: A high voltage power supply for a static neutralizer is disclosed. The high voltage power supply includes a resonant converter and a load with an emitter module having an emitter, reference electrode, and a capacitance value. The resonant converter is disposed to have a resonant frequency and an output coupled to the load. The resonant converter generates an output waveform with an amplitude sufficient for generating to ions by corona discharge when the load receives the output waveform. The load is predominantly capacitive when the resonant converter is operating at the resonant frequency.

  • Patent number: 6234464
    Abstract: A microencapsulated unsaturated fatty acid or fatty acid compound or mixture of fatty acids and/or fatty acid compounds, and particularly an omega-3-fatty acid or omega-6-fatty acid or an ethyl ester or a glyceride thereof or a mixture of such fatty acids and/or fatty acid compounds. Fatty acid compounds are understood to include derivatives. Particles of the compounds are provided with capsule walls composed of two layers. The inner layer is composed of gelatin A, gelatine B. casein or an alginate, or of a derivative or salt of one of these polymers. The outer layer is composed of gelatin B, gum arabic, pectin or chitosan or a derivative or salt of one of these polymers.

  • Patent number: 5793875
    Abstract: A directional acoustic receiving system is constructed in the form of a necklace including an array of two or more microphones mounted on a housing supported on the chest of a user by a conducting loop encircling the user's neck. Signal processing electronics contained in the same housing receives and combines the microphone signals in such a manner as to provide an amplified output signal which emphasizes sounds of interest arriving in a direction forward of the user. The amplified output signal drives the supporting conducting loop to produce a representative magnetic field. An electroacoustic transducer including a magnetic field pickup coil for receiving the magnetic field is mounted in or on the user's ear and generates an acoustic signal representative of the sounds of interest.The microphone output signals are weighted (scaled) and combined to achieve desired spatial directivity responses. The weighting coefficients are determined by an optimization process.
