Abstract: An apparatus for actuating a valve includes an actuator body with a proximal end having a connector for coupling to a valve assembly, and a distal end. A piston assembly having a piston disposed in a piston cylinder is located within the proximal end of the actuator body. A telescoping port assembly extends from the distal end to the piston assembly, the telescoping port assembly having an inner telescoping member and an outer telescoping member. The outer telescoping member has an inner cavity that reciprocatingly receives an end of the inner telescoping member. A bore extends axially through the telescoping port assembly and communicates pressure from a pressure source to the piston cylinder, so that when a pressure media is supplied from the pressure source to the bore, the piston actuates the valve assembly, and the outer telescoping member telescopes outward from the inner telescoping member.

Abstract: Flowmeters are disclosed herein that include one or more flow path features for improving the measurement accuracy or other aspects of the flowmeter. In some embodiments, the flowmeter includes a measurement section having a non-circular transverse cross-section in which one or more sensors for measuring flow are disposed. The non-circular measurement section can reduce distortion of ultrasonic waves, facilitate chordal measurements with flush-mounted transducers, and reduce the propagation distance between paired transducers. In some embodiments, the flowmeter includes a conditioning section with diametrically opposed longitudinal rib protrusions. The protrusions can reduce swirling flow, direct liquid components of a multi-phase flow towards the sidewalls of the flow path, and guide ballistic particles through the center of the flow path away from sensitive measurement devices.

Patent number: 9083183
Abstract: A method for use in monitoring a utility network includes identifying, via a computing device, at least one contingent performance violation associated with a first element of a plurality of transmission elements of a utility network. The method includes presenting by the computing device a risk indicator corresponding to the contingent performance violation around a graphical representation of the first element.

Patent number: 9083220
Abstract: A method for servicing a rotor of a generator includes the steps of, dismantling a non-drive end of the generator, removing insulation from portions of an existing Wye ring and existing connection lugs, removing portions of the existing Wye ring near the existing connection lugs, installing a replacement Wye ring in the generator, connecting the replacement Wye ring to the existing connection lugs, and insulating the replacement Wye ring and the existing connection lugs. The method is performed on the generator in-situ.

Patent number: 9083233
Abstract: Systems, methods, and apparatus for providing a dynamic break and distortion filter. In one embodiment, an apparatus can include an inverter providing alternating current (AC) power at one of a first and second chopping frequency and a filter. The filter can include an input port receiving the AC power and an output port providing output power by selectively passing the AC power from the input port to the output port. The filter may further include an inductor electrically connected to one of the input port and output port and a capacitor electrically connected to the inductor and to a resistor, wherein current does not substantially flow through the inductor and capacitor at the first chopping frequency and does substantially flow through the inductor and capacitor at the second chopping frequency, and wherein the AC power with the second chopping frequency is dissipated in the resistor.

Patent number: 9083242
Abstract: An interleaved LLC converter, a method of operating an LLC converter and a power supply are disclosed herein. In one embodiment, the LLC converter includes: (1) a plurality of LLC power channels, with each of the plurality having an independent power input and (2) a compensation controller configured to actively adjust the independent power inputs to substantially match output voltage and current levels for a given load condition and a common operating frequency of the plurality of LLC power channels.

Patent number: 9083261
Abstract: A control system includes a fundamental control unit, first and second compensation control units, a switch control unit, and a switch implementation unit. The fundamental control unit generates fundamental commands to implement fundamental power conversion operation for a converter. The first compensation control unit generates a first compensation signal for injection into the fundamental command to balance neutral point voltage when the converter is in operation in a first state. The second compensation control unit generates a second compensation signal for injection into the fundamental command to balance neutral point voltage when the converter is in operation in a second state. The switch control unit detects first and second states of the converter and provides first and second switch signals respectively.

Patent number: 9083374
Abstract: Decomposing a value range of the respective syntax elements into a sequence of n partitions with coding the components of z laying within the respective partitions separately with at least one by VLC coding and with at least one by PIPE or entropy coding is used to greatly increase the compression efficiency at a moderate coding overhead since the coding scheme used may be better adapted to the syntax element statistics. Accordingly, syntax elements are decomposed into a respective number n of source symbols si with i=1 . . . n, the respective number n of source symbols depending on as to which of a sequence of n partitions into which a value range of the respective syntax elements is sub-divided, a value z of the respective syntax elements falls into, so that a sum of values of the respective number of source symbols si yields z, and, if n>1, for all i=1 . . . n?1, the value of si corresponds to a range of the ith partition.

Patent number: 9083537
Abstract: An energy management system comprises one or more appliances, a remote device, and a communication device. In one embodiment, the communication device forms a physical connection with the remote device and thereafter a physical connection with an associated appliances. The first physical connection binds the communication to the remote device, thereby forming a secure connection over which inputs and outputs can be exchanged between the remote and the associated appliance when the communication device is connected to the appliance.
