  • Publication number: 20120143279
    Abstract: Disclosed herein are kits and methods for treating appetite suppressing disorders and disorders with an increased metabolic rate by neuromodulation. A method of treating an appetite suppressing disorder or a disorder with an increased metabolic rate in a patient may include identifying the brain structure that is subject to modulation in the patient; and modulating the activity of one or more brain structures by applying electrical stimulation to one or more brain structures of a patient. A kit may include: a neuromodulation device; and instructions for using the neuromodulation device to modulate activity of a brain structure by applying electrical stimulation to one or more brain structures of a patient for treatment of an appetite suppressing disorder or a disorder with an increased metabolic rate.

  • Publication number: 20110112603
    Abstract: The present disclosure relates to methods, devices, and systems used for the treatment of mood, anxiety, cognitive, and behavioral disorders (collectively, neuropsychiatric disorders) via stimulation of the superficial elements of the trigeminal nerve (“TNS”). More specifically, minimally invasive systems, devices and methods of stimulation of the superficial branches of the trigeminal nerve located extracranially in the face, namely the supraorbital, supratrochlear, infraorbital, auriculotemporal, zygomaticotemporal, zygomaticoorbital, zygomaticofacial, nasal and mentalis nerves (also referred to collectively as the superficial trigeminal nerve) are disclosed herein.

  • Publication number: 20110106220
    Abstract: The present disclosure relates to methods, devices and systems used for the treatment of neurological disorders via stimulation of the superficial elements of the trigeminal nerve (“TNS”). More specifically, minimally invasive methods of stimulation of the superficial branches of the trigeminal nerve located extracranially in the face, namely the supraorbital, supratrochlear, infratrochlear, auriculotemporal, zygomaticotemporal, zygomaticoorbital, zygomaticofacial, nasal, infraorbital, and mentalis nerves (also referred to collectively as the superficial trigeminal nerve) are disclosed herein. Systems and devices configured for therapeutic stimulation of the branches of the trigeminal nerves, such as the superficial trigeminal nerve, and their methods of application are also described.

  • Publication number: 20090010462
    Abstract: A rechargeable battery module for powering an external electronic device comprises a rechargeable thin film battery, a receiving induction coil, and a battery control circuit. The battery control circuit comprises a rectifier circuit, a battery charging circuit to limit the charging voltage provided by the direct current to the battery to a maximum charging voltage, and a battery discharging circuit to terminate a discharge voltage from the battery to less than a predetermined discharge voltage. A pair of output terminals to provide an output voltage to an external electronic device.

  • Patent number: 6330794
    Abstract: The invention is directed to an apparatus and a method for the reduction of pollutants in the exhaust stream of a combustion engine. Radicals are produced using a corona discharge in the combustion gas stream of the engine, either in the precombustion gas stream or from water in the exhaust gas. When the radicals are produced from the exhaust gas stream, the radicals may be produced using a corona discharge placed directly in the exhaust stream leading to the catalytic convertor, or a portion of the exhaust stream may be diverted to a remote corona discharge radical generator. The corona discharge in the generator produces radicals in the diverted exhaust gas, and the exhaust gas containing radicals is then conveyed to the exhaust gas stream at a point upstream of the catalytic convertor.

  • Patent number: 4862160
    Abstract: A computerized transceiver repeatedly sweeps through a set of transmit/receive frequencies to interrogate collectively a plurality of groups of items in a stocking area. Items in each group are tagged with a printed circuit transponder tuned to frequencies uniquely assigned to each group. Data returned is stored and combined mathematically by the computer to arrive at the total number of items in each group. The system is particularly adapted for taking inventory of a large number of retail shelf goods using a mobile transceiver.

  • Patent number: 4624140
    Abstract: The inside surface of a conductive vessel (preferably spherical) with insulated adjacent segments is coated with a dielectric layer. The vessel is then partly filled with a conductive liquid-like material such as mercury having an upper surface which remains approximately horizontal irrespective of the inclination of the vessel. The capacitance between the segments and liquid varies as a function of the vessel's inclination. Vibration-induced surface action also produces varying capacitance which can be detected for seismometer applications and the like.
