  • Publication number: 20160303694
    Abstract: A steam generator includes a lower integrated tubesheet and plenum (ITP) configured to receive feedwater and a first set of heat transfer tubes fluidly coupled to a plurality of stubs protruding from a first side of the lower ITP. A second set of heat transfer tubes fluidly couples to plurality of stubs protruding from a second side of the lower ITP. The first set of heat transfer tubes is coiled in a substantially clock-wise direction, and the second set of heat transfer tubes is coiled in a substantially counter-clockwise direction. The steam generator further includes an upper ITP fluidly coupled to the first and second set of heat transfer tubes, wherein the feedwater entering the lower ITP is converted to steam in the first and second sets of heat transfer tubes. The upper ITP is configured to transport the steam away from the steam generator.

  • Publication number: 20160246975
    Abstract: A multi-functional device is attached to a secure network and includes a control circuit. The control circuit receives indications as to whether a user is authenticated to use the multi-functional device and in response, generates and sends a control signal to the multi-functional device. As long as the multi-functional device continues to receive the control signal, the multi-functional device remains in an operational mode to allow the authenticated user to access the multi-functional device functions. If the multi-functional device ceases to receive the control signal, the multi-functional device deactivates itself.

  • Patent number: 9264077
    Abstract: A mobile communications device may include an RF signal source configured to generate RF signals over an RF frequency band(s), and an RF transmitter coupled to the RF signal source. The RF transmitter may include an RF amplifier configured to operate over a plurality of different power control levels. The RF amplifier may have an input configured to receive the RF signals from the RF signal source and an output having an impedance which changes based upon changes between the different power control levels. The RF transmitter may further include a shunt resistor(s) coupling the output of the amplifier to a voltage reference, and the shunt resistor(s) may be configured to decrease a highest impedance change of the RF amplifier output to below a threshold impedance level. An antenna(s) may be coupled to the output of the RF amplifier to operate over the at least one RF frequency band.

  • Patent number: 8980395
    Abstract: A composite part includes a first composite section and a second composite section connected by a flexible section. The first composite section has a laminated structure including multiple layers of reinforcement material supported by a matrix material. The second composite section has a laminated structure including multiple layers of reinforcement material supported by a matrix material, and a flexible composite section joins the first composite section to the second composite section. The flexible composite includes multiple layers of a fabric material supported by a flexible elastomer. The multiple layers of the fabric material overlap with the first composite section and the second composite section by being layered in between at least a portion of the multiple layers of reinforcement material forming the laminated structures of the first composite section and the second composite section.

  • Patent number: 8881109
    Abstract: Embodiments of a system (such as a computer system), a method, and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to test software that includes instructions for a graphical user interface with objects that receive values in associated fields. In particular, during testing, the system identifies the objects and associated expected values in the software, tests the software based on the identified objects and the expected values, and generates a flow file which includes the testing operations and corresponding results. Moreover, during the testing, the system may generate a compliance document which includes the testing operations and the results.
