    摘要： A method of controlling a brushless motor that includes rectifying an alternating voltage to provide a rectified voltage, and exciting a winding of the motor with the rectified voltage. The winding is excited in advance of predetermined rotor positions by an advance period that is updated in response to a zero-crossing in the alternating voltage. Additionally, a control system that implements the method, and a motor system that incorporates the control system.

    摘要： There is presently provided a device for detecting an analyte particle in a sample. The device comprises a chamber having an interior surface upon which is located an electrode array. The electrode array comprises pairs of electrodes, each pair having an inner electrode and an outer electrode that substantially surrounds the inner electrode. Each pair of electrodes is coated with a capture molecule that recognises and binds the analyte particle that is to be identified and quantified. The device uses a combination of dielectrophoresis and impedance measurements to capture and measure analyte particles from a sample.

    摘要： A concentrated solar energy device is connectable to a solar array and includes a photovoltaic cell that provides electrical energy and heat from a solar energy source, a thermally conductive element, concentrating optics, and a housing. The concentrating optics are positioned between the solar energy source and the photovoltaic cell and are aligned with the solar energy source. The thermally conductive element functions to dissipate heat from the photovoltaic cell. The housing and the concentrating optics are attached to one another and together enclose the photovoltaic cell and a portion of the thermally conductive element. An optical film may be positioned over the concentrating optics during assembly, installation, and/or maintenance of the concentrated solar energy device.

    摘要： The object of the present invention is to provide a method and an apparatus for performing synchronization among neighboring base stations in the wireless communication network. According to the technical solution of the present invention, a base station turns off a transmitter randomly to receive a synchronization signal from neighboring base stations, and obtains a new local synchronization reference time based on the synchronization reference time of other neighboring base station. With the apparatus and the method provided by the present invention, the strongly robust synchronization among base stations is realized.

    摘要： A non-linear element is formed on a flexible substrate by securing the substrate to a rigid carrier, forming the non-linear element, and then separating the flexible substrate from the carrier. The process allows flexible substrates to be processed in a conventional fab intended to process rigid substrates. In a second method, a transistor is formed on a insulating substrate by forming gate electrodes, depositing a dielectric layer, a semiconductor layer and a conductive layer, patterning the conductive layer to form source, drain and pixel electrodes, covering the channel region of the resultant transistor with an etch-resistant material and etching using the etch-resistant material and the conductive layer as a mask, the etching extending substantially through the semiconductor layer between adjacent transistors. The invention also provides a process for forming a diode on a substrate by depositing on the substrate a first conductive layer, and a second patterned conductive layer and a patterned dielectric layer over parts of the first conductive layer, and etching the first conductive layer using the second conductive layer and dielectric layer as an etch mask. Finally, the invention provides a process for driving an impulse-sensitive electro-optic display.

    摘要： A method of calibrating a metabolic analyzer incorporating an oxygen analyzer and a NDIR carbon dioxide analyzer in the field that does not require the use of gas cylinders containing gases of known concentration is described. In calibrating the CO2 detector, at the time of factory setup, the detector output for a gas of a known concentration is measured and stored in the memory of the metabolic analyzer's microprocessor, as is the detector output voltage when the IR source is dimmed by a known percentage. Subsequently, in the field, CO2 levels in ambient air and cell pressure are measured at two different flow rates through the sample chamber and the IR source is again dimmed by the same percentage as had been used at the time of factory setup. Based upon the resulting readings, both the zeroing and span adjustment factors can be computed.
