  • Patent number: 10224908
    Abstract: An integrated circuit may include path delay calibration circuitry. The calibration circuitry may be configured to calibrate respective delay paths so that data and control signals travelling through the respective delay paths experience proper propagation delays during normal user operation. The calibration circuitry may include a high frequency error calibration circuit, a monitoring circuit, and a calibration processing circuit. The high frequency error calibration circuit may be used to compute first calibration settings that take into account jitter and process variations. The monitoring circuit may be used to measure a proxy parameter of interest.

  • Patent number: 10215587
    Abstract: A method for detecting a human's steps and estimating the horizontal translation direction and scaling of the resulting motion relative to an inertial sensor is described. When a pedestrian takes a sequence of steps the displacement can be decomposed into a sequence of rotations and translations over each step. A translation is the change in the location of pedestrian's center of mass and a rotation is the change along z-axis of the pedestrian's orientation. A translation can be described by a vector and a rotation by an angle.

    Abstract: A circuit comprising a substrate with sectors on the substrate is provided, each sector comprising clock and data lines, a controller in electrical communication with the clock and data lines, a counter bias line, an amplifier input line and nano-electronic measurement devices on the substrate. A source of each device is coupled to the counter bias line and a drain of each device is coupled to the amplifier input line to obtain an electrical signal on the drain, the identity of which is determined by electrical interaction between the device and a charge label. Each device drain is gated by a corresponding switch between an on state, in which the drain is connected to the amplifier input line, and an off state, in which the drain is isolated from the amplifier input line. The controller controls switch states responsive to clock signal line pulses and data input line data.

  • Patent number: 9645282
    Abstract: An adaptive weather interrogation system capable of determining whether currently available weather for a particular trajectory or portion thereof, a particular volume of space or geospatial point meets subscriber operations and requirements. More specifically, the system provides the capability to determine the “best” weather information by evaluating the weather data and associated weather quality, accuracy or confidence attribute values against subscriber operations and requirements. If the weather data, quality, accuracy, and confidence do not meet the subscriber's requirements, the system is capable of interrogating weather data sources for additional or updated weather data to meet the subscriber's needs.

  • Patent number: 9581018
    Abstract: Disclosed is a system and method for horizontal directional drilling (HDD). The system and method utilize predictive algorithms to both characterize the soil within the borehole and to quantify instability within the drillstring. The soil characteristics are represented by a soil coefficient (?) which relates the curvature of the borehole with the length of thrust of the drill rig as well as by comparison of thrust while thrusting with torque while drilling. The value of (?) is obtained by comparison of the historical orientation of the drilling head over the length of the borehole and the borehole shape as determined by an arbitrary navigation sensor. Drillstring instability is determined as a function of historical thrust and torque efficiencies and windup over the length of the borehole.

    Abstract: Systems, apparatus and methods for quantifying and identifying diversion of electrical energy are provided. Bypass and tap diversions may be identified in an electric utility power distribution inventory zone having both bypass and tap diversions. Bypass diversion factors for consumer nodes in an inventory zone are determined by finding a solution to a system of load balance equations having slack variables representing aggregate tap loads for the inventory zone and in which consumer load profile data is scaled by the bypass diversion factors, which solution minimizes an objective function whose value is positively related to the sum of the slack variables representing the aggregate tap loads.

  • Patent number: 9228945
    Abstract: A sensor chip includes a substrate, a relief structure composed of protruding sections formed so as to be arranged on a surface of the substrate to have a lattice shape and a recessed section between the protruding sections, and fine metal particles arranged along upper ridge lines of the respective protruding sections of the relief structure, the protruding sections being adjacent to each other, having a minute gap with which the surface plasmon resonance occurs. By irradiating the gap between the fine metal particles with a laser beam, the localized surface plasmon resonance occurs more efficiently. As a result, the sensor chip capable of taking out the surface enhanced Raman scattering to thereby detect the substance with high sensitivity can be realized.

  • Patent number: 9176121
    Abstract: A method of identifying the elements of a blood sample including placing an aliquot of blood on a transparent substrate such as a coverslip. The blood is allowed to stand and the cells to settle to form a layer or matrix. Inverted microscopy is used to identify the elements in the sample. Various forms of illumination may be used alone or in multiple combinations. The method improves the accuracy due to homogenous distribution of formed elements in the wet drop or aliquot, simplifies the method, lowers the cost of the test and results in a shortened analytical cycle time.

  • Patent number: 8817270
    Abstract: An apparatus and associated method for testing a non-symmetric (e.g., phi-polynomial) surface. The apparatus uses several simple (singlet) optical elements (e.g., an Offner null configuration) and a tilted optic under test in combination with an active optical element (e.g., actuated, deformable membrane mirror, optical phase modulator, etc.) that together form a null or quasi-null that allows for conventional null-based interferometry. This solution solves the problem of exceeding the dynamic range of a conventional interferometer when trying to test non-symmetric optical surfaces.
