    摘要: The invention relates to a coil arrangement comprising at least one transmitting coil for generating a primary magnetic field; and a plurality of measurement coils; wherein the at least one transmitting coil (408, 409) and the plurality of measurement coils (410, 411) are arranged in such a way that the flux curve of the primary magnetic field generated by a transmitting coil (409) among said at least one transmitting coil (408, 409) passes into and out of a first measurement coil (410) among said plurality of measurement coils (410, 411), the first measurement coil being the coil closest to the transmitting coil. By enabling the flux of the primary magnetic field to pass into and out of a first measurement coil, the signal induced on the first measurement coil by the positive and negative flux can be compensated, resulting in a reduction of the signal strength of the induced signal on the measurement coil and the signal dynamic range.

    摘要: A linearized thermal and optical model of an optical integrated circuit can be used to temperature-stabilize one or more optical elements of the circuit (455) using active temperature regulation. To stabilize a single optical element, such as an arrayed waveguide grating (AWG), a temperature sensor (425) and a heater (427) can be provided proximate to the grating. Thermal and optical coefficients can be then used to select an appropriate temperature set-point for the temperature controller (400) that receives readings from the sensor and determines the power dissipated in the heater. Multiple AWG's can be stabilized individually, lumping cross- heating factors together with other environmental factors.

    摘要: The method of positioning a Doppler ultrasound transducer for performing blood flow measurement according to the invention comprises the steps of: detecting a pressure oscillation signal from an inflated cuff placed on patient's artery; detecting an ultrasound pulse signal from the Doppler ultrasound transducer placed along the artery; deriving a first signal from the pressure oscillation signal and the ultrasound pulse signal, the first signal indicating the degree of synchronization between the pressure oscillation signal and the ultrasound pulse signal; and outputting an indication signal to indicate the Doppler ultrasound transducer is in a desired position when the first signal satisfies a predefined condition. Since the synchronization property of the cuff pressure oscillation signal and the ultrasound signal caused by the blood flow is utilized to determine whether the transducer is well positioned or not, ultrasound signal, which is a pulse signal but not reflecting the blood flow of the artery, could be determined as not in synchronization with the oscillation signal and therefore the accuracy of the positioning could be improved.

    摘要: The invention relates to a method and a system for magnetic induction tomography, the system comprising: at least one transmitting coil (312, 314) for generating a primary magnetic field to be applied to the object of interest (301); and at least one measurement coil arrangement (315, 317) for measuring electric signals induced by a secondary magnetic field which is generated by the object of interest in response to the primary magnetic field, wherein the at least one measurement coil arrangement comprises a plurality of measurement coils which are positioned in substantially the same plane. By using a plurality of independent measurement coils positioned in a plane so as to replace a conventional single measurement coil, the measurement coil across which the measured difference voltage is most sensitive to a change of the secondary magnetic field can be selected for calculating the change of conductivity distribution, resulting in an improved sensitivity of a MIT system.
