  • Publication number: 20170149437
    Abstract: Embodiments relate to a voltage oscillator (VCO) that uses a replica bias circuit to generate a cascode bias voltage. The VCO generate an output periodic signal having a frequency and phase that is less or not susceptible to voltage swings by using a bias voltage generated in a replica bias circuit that replicates a voltage-to-current converter in the VOC. The bias voltage is generated and regulated according to a power supply voltage that supplies power to the VCO to account for voltage variations in the power supply voltage.

  • Publication number: 20150093202
    Abstract: A new jacket design method is disclosed, especially for deepwater water heavy jacket applications. The method utilizes a special type of air bags, called Ship Launching Air Bags (SLAB), to provide low cost temporary buoyancy used for jacket installation purpose only. A designer only needs to satisfy the jacket stiffness for the resistance of environmental and gravity loads without the consideration of jacket reserve buoyancy. The required jacket reserve buoyancy could be increased with the utilization of temporally attached SLABs during the jacket installation.

  • Patent number: 8886267
    Abstract: A cryogenically-cooled HTS cable is configured to be included within a utility power grid having a maximum fault current that would occur in the absence of the cryogenically-cooled HTS cable. The cryogenically-cooled HTS cable includes a continuous liquid cryogen coolant path for circulating a liquid cryogen. A continuously flexible arrangement of HTS wires has an impedance characteristic that attenuates the maximum fault current by at least 10%. The continuously flexible arrangement of HTS wires is configured to allow the cryogenically-cooled HTS cable to operate, during the occurrence of a maximum fault condition, with a maximum temperature rise within the HTS wires that is low enough to prevent the formation of gas bubbles within the liquid cryogen.

  • Patent number: 8625012
    Abstract: Described herein is a circuit and related method for improving the dynamic range and the linearity characteristic of a CMOS image sensor. In various embodiments of the CMOS image sensor, a current sampler, a comparator, and a 1-bit memory are incorporated in each pixel circuit. In the image sensor, pixels are arranged in columns and a column slice is used to read the digital and analog singles from each column. In addition, a calibration circuit is incorporated in the sensor circuit for providing calibration current, which is used to generate calibration parameter. The image sensor operates in three non-overlapping modes: the difference mode, the WDR mode, and the calibration mode. The image sensor is switched among the three modes by control signals, which are provided to the image sensor by various control circuits. The image sensor normally operates in the difference mode and switches to the WDR mode when the difference between consecutive frames is over a threshold.
