    摘要: An Inductively Coupled Power Transfer (ICPT, or IPT) pick-up circuit is provided which includes an inductive element L2 provided between a resonant circuit and a rectifier means. A DC inductor is not required. The inductive element L2 is chosen to have substantially the same inductance as that of the pick-up coil L1, reducing or eliminating the reactive component of the reflected impedance.

    摘要: An Inductive Power Transfer (IPT) pick-up apparatus includes a magnetically permeable core, a first coil, being wound about the core so as to be inductive coupled therewith such that a current induced in the first coil is most sensitive to a first directional component of magnetic flux and a second coil, being wound about the core so as to be inductively coupled therewith such that a current induced in the second coil is most sensitive to a second directional component of magnetic flux. The first directional component is substantially orthogonal to the second directional component.

    摘要: The present invention is concerned with methods for the assessment of pulmonary function and/or disorders, and in particular for diagnosing predisposition to and/or severity of chronic obstructive pulmonary disease in smokers and non-smokers using analysis of genetic polymorphisms and altered gene expression, particularly with regard to genes involved in matrix remodelling, anti-oxidant defence and the inflammatory response.

    摘要: The present invention provides a system for controlling one or more operating unites in an inductive power transfer (IPT) system. Each operating unit includes a pick-up coil that takes power from a primary conductor or track over an air gap. The operating unit is controlled by frequency modulating the primary conductor power supply to send a control instruction which is decoded by the operating unit. The instruction is decoded by generating a signal using a local oscillator in the operating unit and using the signal to detect changes in the frequency of the current in the primary conductor. Such a system can be used, for example, to control inductively powered road-studs that include a light source for controlling traffic on a roadway. A narrow band modulated data transmission system and method for controlling an operating unit are also provided.

    摘要: PCT No. PCT/NZ97/00053 Sec. 371 Date Nov. 3, 1998 Sec. 102(e) Date Nov. 3, 1998 PCT Filed May 2, 1997 PCT Pub. No. WO97/42695 PCT Pub. Date Nov. 13, 1997Loosely coupled inductive power for charging batteries is rectified from a first power pickup winding and the resulting current source is connected to a battery unit. Each current source is controlled by shorting a second resonant winding. Battery banks may be charged using multiple isolated position-tolerant pickups independently controlled according to the condition of the connected battery unit and by overall commands communicated over an isolated link. The battery unit may be a single cell. In a self-stabilizing bank or monoblock a primary inductive conductor is energized using all the cells, individual cells are separately monitored by control means and any below-average cell can be individually charged from the inductive conductor, thus correcting between-cell variations. The charge in all cells within a bank can be held within 30% to 70% of full charge and prevented from drifting towards full or empty during repetitive charge and discharge times.

    摘要: A resonant converter is provided which may be used for supplying power to the primary conductive path of an inductively coupled power transfer (ICPT) system. The converter includes a variable reactive element in the resonant circuit which may be controlled to vary the effective inductance or capacitance of the reactive element. The frequency of the converter is stabilised to a nominal value by sensing the frequency of the converter resonant circuit, comparing the sensed frequency with a nominal frequency and varying the effective inductance or capacitance of the variable reactive element to adjust the converter frequency toward the nominal frequency.
