  • Patent number: 11772099
    Abstract: The present invention relates to a microfluidic system including a temperature controller and a thermoplastic microfluidic chip that enables rapid PCR in a PCR chamber of the microfluidic chip. Thermal control of the PCR chamber is achieved by applying voltage to heater electrodes patterned directly onto one layer of the microfluidic chip. The temperature controller adjusts the voltage applied to the heater electrodes by changing temperature controller parameters selected to minimize duration of each PCR cycle. Furthermore, simple operation of the microfluidic chip is provided through using an integrated passive capillary valve, requiring minimum operator intervention and eliminating the need for fluidic interfacing, pumping, or metering during chip loading.

  • Patent number: 11534763
    Abstract: Droplet interfaces are formed between droplets in an electro-wetting device comprising an array of actuation electrodes. Actuation signals are applied to selected actuation electrodes to place the droplets into an energised state in which the shape of the droplets is modified compared to a shape of the droplets in a lower energy state and to bring the two droplets into proximity. The actuation signals are then changed to lower the energy of the droplets into the lower energy state so that the droplets relax into the gap and the two droplets contact each other thereby forming a droplet interface. The use of sensing electrodes in the device permit electrical current measurements across the droplet interface. The sensing electrodes can be used for either (i) applying a reference signal during droplet actuation or (ii) recording electrical current measurements.

  • Patent number: 10120056
    Abstract: A method of calibrating an impedance-matching current sensor (IMCS) is provided. The IMCS has an equivalent sensing impedance and is connected in parallel to an object under test. The method includes steps of: using an alternating-current (AC) current source to provide a first AC current flowing through the object under test and provide a second AC current flowing through the IMCS; designing the equivalent sensing impedance to make the first AC current much greater than the second AC current; proportionally converting the second AC current into a sense voltage; and adjusting a magnitude of the sense voltage to be proportional to a magnitude of the first AC current. Accordingly, it is to significantly overcome problems of unreliability and instability of the DC-to-DC conversion system caused by temperature, aging, DC bias variation, or parasitic effect, thus maintaining correct sensed results of the current sensor in transient response optimization.

  • Patent number: 9000778
    Abstract: A method for underground pipeline monitoring in which a continuous alternating electrical current having a current frequency in a range of about 1 kHZ to about 8 kHz is imparted onto a pipeline, producing an alternating magnetic field at the current frequency along the pipeline. Distributed along the pipeline is a network of RFID tag sensors which absorb an amount of energy from the alternating magnetic field. The impedance of the sensors is modulated, producing a modulated sensor impedance which is detected at a location proximate the location at which the continuous alternating electrical current is imparted onto the pipeline.

  • Patent number: 9000774
    Abstract: A system for measuring the conductivity of a material-under-test includes a support structure, an upper magnet mounted to the support structure and a free-floating magnet below the fixed magnet. The system includes a diamagnet positioned between the fixed magnet and the free-floating magnet such that the free-floating magnet floats in the air beneath the diamagnet and a rotation detection assembly configured to detect a rotation rate of the free-floating magnet, where the rotation rate is based on a drag torque effect of a material-under-test on the free-floating magnet. The system also includes a conductivity calculation unit configured to calculate at least one of a conductivity or a resistivity of the material-under-test based on the detected rotation rate of the free-floating magnet.

  • Patent number: 8994383
    Abstract: The invention disclosed enables sensing of the electrical permittivity of an object. A sensor is provided that includes a dielectric layer that presents a surface defining the base of a volume in which a test object may be placed and an electrically active layer beneath the dielectric layer, comprising a first set of electrodes that extend in a first direction and a second set of electrodes that extend in a second direction that is perpendicular to the first direction. By applying a signal to a first electrode in said first set of electrodes, an electric field is generated that extends outside of the sensor. An output signal is then produced in each of the second electrode set by capacitive coupling to the first electrode. The electrical permittivity of the volume above the first receiver electrode is then determined based on the output signals in the said set of electrodes.
