  • Patent number: 10429420
    Abstract: A system for measuring and mapping sheet resistivity of the film on flat-panel has a frame, a collection of leveling chucks, a probe-mounting assembly, and a collection of four-point probes. The probe-mounting assembly is a frame that holds the four-point probes in place. The leveling chucks and the probe-mounting assembly are mounted onto the frame, within the probe chamber. The flat panel is positioned in between the probe-mounting assembly and the leveling chucks. The sheet resistivity measurement by each of the collection of four-point probes can be done by electrical switching instead of mechanical repositioning and the flat panel transportation to and from the measurement position only needs to be done in one round trip instead of two, thus much time is saved. Also, the leveling chuck's speed in pressing the flat panel against the collection of four-point probes can be well controlled to avoid damaging of the flat panel.

  • Patent number: 10429434
    Abstract: Disclosed are an on-chip reliability monitor and method. The monitor includes a test circuit with a test device, a reference circuit with a reference device, and a comparator circuit. The monitor periodically switches from operation in a stress mode, to operation in a test mode, and back. During each stress mode, the test device is subjected to stress conditions that emulate the operating conditions of an on-chip functional device while the reference device remains essentially unstressed. During each test mode, the comparator circuit compares a parameter of the test device to the same parameter of the reference device and outputs a status signal based on the difference between the parameters. When the status signal switches values, it is an indicator that the functional device has been subjected to a predetermined number of power-on-hours. Optionally, multiple monitors can be cascaded together to more accurately monitor stress-induced changes over time.

  • Patent number: 10429464
    Abstract: In a magnetic resonance apparatus having a scanner that generates a basic magnetic field in an imaging volume, and an operating method to acquire data from an entirety of a recording volume, wherein the scanner has a global shim coil acting on the entire imaging volume, and a local shim coil acting, with the global shim coil, on a sub-volume containing a region of interest, a first adjustment volume is established that contains the recording volume. A smaller, second adjustment volume is established containing the region of interest, and at most, the sub-volume. Using a field map of the basic magnetic field that covers the first adjustment volume, shim currents are respectively identified for the global shim unit, for homogenizing the first adjustment volume, and for the local shim unit, for homogenizing the second adjustment volume, accounting for the effect of the first shim currents on the second adjustment volume.

  • Patent number: 10416106
    Abstract: A remote wireless moisture sensing unit is insertable into soil. The sensing unit includes at least three capacitive sensors positioned at three spaced apart levels with respect to the surface of the soil. The capacitance of each sensor increases in the presence of increased moisture content of the soil proximate to the sensor. An analog multiplexer selectively routes each sensor to an input to a capacitively-controlled oscillator to cause the oscillator to generate a clock signal having a frequency responsive to the capacitance of the currently connected sensor and thus responsive to the moisture content proximate to the currently selected sensor. A processor generates a respective data value for the frequency corresponding to each sensor and transmits the data values for the sensors via a radio frequency transceiver. The data values are processed to determine the moisture content of the soil at the three sensor levels.

  • Patent number: 10401203
    Abstract: A flowmeter for use in a borehole that includes a transmitter and receivers spaced axially away from the transmitter. Energizing the transmitter creates electrical field lines that extend between the transmitter and the receivers, and that pass through fluid flowing past the flowmeter. The magnitude of the electrical field lines at each of the receivers is measured, and varies in response to different types of fluid flowing past the flowmeter, and changes in phase of the fluid. Example transmitters and receivers include coils and electrodes. The transmitters and receivers can define elongate arrays, where the arrays are arranged parallel to, oblique, or perpendicular to an axis of the borehole. Multiple array orientations provide a radial cross sectional image of the flowing fluid. Thus not only can multi-phase flow be detected, but the type of flow regime can be identified.
