  • Patent number: 10718786
    Abstract: A flow cell and cartridge assembly may be loaded into a processing system, such as for genetic sequencing. The system locates the assembly and is then actuated to move the assembly to a desired reference position in both X- and Y-directions. Further actuation causes clamps to contact the flow cell, the cartridge, or both to exert a hold-down force during processing. Further hold-down forces may be provided by a vacuum chuck. Fluid connections are also made by manifolds that contact the flow cell. The hold-down forces counteract the forces needed for sealing the manifolds to the flow cell.

The first receiver measures an output signal from the DUT responsive to the stimulus signal, and the second receiver measures the reference signal from the second signal source. The processor mathematically suppresses a carrier of the output signal by determining a difference between the measured output signal and the measured reference signal, and determines the residual phase noise of the DUT based on the difference.

  • Patent number: 10718813
    Abstract: A method of automatically identifying an anomalous condition of an induction motor by normalizing the voltage measured across its terminals relative to the power flow to the motor or the motor's impedance. The starting and/or run current and associated voltage of the motor is measured, and a voltage variation between the measured voltage and the motor's rated voltage is determined. The power flow or impedance at the voltage variation is calculated to determine an expected power flow or impedance at the measured voltage variation. The actual power flow or impedance is compared against a nominal or expected power flow or impedance or a statistical comparison is carried out on a historical set of power flow or impedance values within an expected range at the voltage variation. When the measured values deviate from the expected ones, an alarm is triggered to indicate a potential anomaly with the motor or external thereto.

  • Patent number: 10718822
    Abstract: To reduce the rate at which a false alternating current (“AC”) loss alarming signal is generated, but at the same time detect an actual AC loss situation in a timely manner, the disclosed method describes an AC line power loss detection and active verification method. If the AC line input voltage dips momentarily lower than a standard sine wave amplitude, the AC line may not be considered lost as long as it still has energy to drive a load. The method inserts a momentary load across the AC line and compares the AC line voltage before and after the extra load is applied. If the AC power is present, this extra loading will increase the AC loading current momentarily, but will not affect the AC line voltage. However, if the AC power is lost, such loading will lower the AC line voltage, indicating a loss of power.

  • Patent number: 10718823
    Abstract: A device for open load diagnosis of a signal line in a digital system in which a logic state is represented by a band of voltages lying between first and second voltage limits is described. The device is configured to cause the signal line to reach a first, stable voltage lying in the band, to apply a second, different voltage to the signal line lying in the band and without leaving the band, to perform a time constant dependent measurement so as to determine a value of a parameter which is or depends on resistance of a load between the signal line and a reference line, to compare the value of the parameter with a reference value of the parameter and, in dependence on comparison, to signal the result.

  • Patent number: 10718825
    Abstract: A magnetic field sensor includes a magnetic sense element and a shield structure formed on a substrate. The shield structure fully encircles the magnetic sense element for suppressing stray magnetic fields along a first axis and a second axis, both of which are parallel to a surface of the substrate and perpendicular to one another. A magnetic field is oriented along a third axis perpendicular to the surface of the substrate, and the magnetic sense element is configured to sense a magnetic field along the first axis. A magnetic field deflection element, formed on the substrate proximate the magnetic sense element, redirects the magnetic field from the third axis into the first axis to be sensed as a measurement magnetic field by the magnetic sense element. At least two magnetic field sensors, each fully encircled by a shield structure, form a gradient unit for determining a magnetic field gradient.

  • Patent number: 10718829
    Abstract: Methods, apparatuses, and computer program products for optimizing utilization of a wireless position sensor are disclosed. In a particular embodiment, a controller of the wireless position sensor receives output from a magnetic-field-dependent sensor of the wireless position sensor. The magnetic-field-dependent sensor is configured to register the strength of a magnetic field of a magnet attached to a mechanical component. In this example, the registered strength corresponds to a position of the mechanical component along a directional path. According to this embodiment, the controller generates a comparison of the output to one or more predefined movement signatures and based on the comparison, determines whether to change an operating state of one or more components of the wireless position sensor.

  • Patent number: 10718833
    Abstract: A magnetic resonance imaging (MRI) system uses a superconducting magnet having a primary coil structure and a shielding coil layer. The primary coil structure comprises at least three sets of coils with significantly different inner diameters, forming a three-bore magnet structure. The three bores are coaxially aligned with a longitudinal axis, with the largest diameter first bore on one side of the magnet and the smallest diameter third bore on another side of the magnet, as well as a medium diameter second bore located axially between the first and the third bores. The first bore allows access for the head and shoulders and permits the head to enter into the second bore for imaging, while the patient's extremities (hands, legs) may access through the third bore for producing images of the extremity joints. The magnet may also be used for other specialist imaging where use of a whole-body MRI is unwarranted, such as the imaging of neonates.
