Patent number: 9332601
Abstract: A two-stage AC-DC power converter for powering a load at a substantially constant current, and related methods and systems. The first stage of the AC-DC power converter includes a conventional power factor correction (PFC) circuit that outputs a direct current (DC) voltage and a DC current. The second stage of the AC-DC power converter includes a low voltage flyback circuit that receives the DC voltage and the DC current. The low voltage flyback circuit includes a flyback transformer and a switch circuit that selectably toggles the substantially constant output current provided by the low voltage flyback circuit to the load between a first and a second, preset constant current. The secondary windings of the flyback transformer are split into two sections, and the switch circuit toggles the two sections of the secondary windings between a series and a parallel configuration to provide the first and second, preset constant currents.

The method includes determining region of interest (ROI) candidates in an image, extracting features from each of the ROI candidates, selecting the optimum ROI based on weighted score of each of the ROI candidate, and calculating brightness value of the selected optimum ROI candidate as brightness feedback. The method and apparatus for image automatic brightness detection according to embodiments of the present invention, can automatically detect the point of interest for clinicians, and then provide a more accurate feedback to the imaging system, in order to provide a more efficient dose management in the imaging system and thus to achieve constant image quality without wasting any dose, thereby further optimizing the dose/IQ performance and the high efficient utilization of the system.

Patent number: 9329065
Abstract: A variable orifice fluid flow sensor is provided that includes a fluid flow passage therethrough formed with a first port portion adjacent to one end of said passage and a second port portion adjacent to the other end of said passage. A bending member is mounted in the fluid flow passage between the first and second port portions and having a fluid flow limiting flapper extending across the fluid flow passage for creating a fluid flow opening in the passage, the size of the opening being variable responsive to fluid flow in said fluid flow passage. A biasing member is also mounted between the first and second port portions and includes at least one biasing element extending away from the biasing member into contact with the bending member to exert a contact force on the bending member.

Patent number: 9329248
Abstract: A non-cylindrical cable balun design having reduced space requirements and that provides for a lighter-weight RF coil is disclosed. The balun includes a balun shell having a non-cylindrical profile, a dielectric foam positioned within the balun shell so as to fill an interior volume defined by the balun shell, and one or more capacitors formed on the balun shell. A non-cylindrical coaxial cable that transmits electromagnetic signals to the balun extends through a length of the balun and is surrounded by the dielectric foam.

Patent number: 9329102
Abstract: A system for optically monitoring a gas turbine engine includes a viewport having an opening disposed within a casing of the gas turbine engine. The opening extends from an interior side of the casing to an exterior side of the casing, and the viewport is configured to receive an image from inside the casing. The system also includes an optical connection positioned outside the casing and optically coupled to the viewport. The optical connection is configured to convey the image from the viewport to a detector array, and the optical connection includes multiple optical fibers fused to one another to form a unitary substantially rigid fiber bundle.

Patent number: 9330876
Abstract: A system for regulating a pressure of a filled-in gas is presented. The system includes a reservoir that stores a reservoir gas adsorbed in a sorbent material at a storage temperature, a gas-filled tube containing the filled-in gas, a controller configured to determine a pressure change required in the filled-in gas based upon signals representative of a pressure of the filled-in gas inside the gas-filled tube and a required pressure threshold, determine an updated temperature of the sorbent material based upon the pressure change required in the filled-in gas, and regulate the pressure of the filled-in gas by controlling the reservoir to change the storage temperature of the sorbent material to reach the updated temperature of the sorbent material.

Patent number: 9330469
Abstract: Systems and methods for boil detection are provided. One example system includes a vision sensor positioned to collect imagery depicting the cooktop and one or more processors implementing instructions to perform operations. The operations include obtaining a first frame of imagery and a second frame of imagery from the vision sensor. The first frame of imagery and the second frame of imagery respectively depict the cooktop. The operations include identifying a plurality of motion vectors based on the first and second frames of imagery. The operations include generating a histogram describing a characteristic of the plurality of motion vectors. The operations include calculating a dissimilarity score. The dissimilarity score describes a difference between the histogram and a pre-learned histogram. The pre-learned histogram describes the characteristic for imagery depicting boiling liquid.
