Dimmable screw-in compact fluorescent lamp having integral electronic ballast circuit

A dimmable ballast circuit for a compact fluorescent lamp controls the intensity of a lamp tube in response to a phase-control voltage received from a dimmer switch. The ballast circuit generates a lamp current through the lamp tube having a substantially constant envelope such that flicker in the lamp tube and electromagnetic interference (EMI) noise on an AC voltage supply are minimized. The dimmable ballast circuit comprises a high speed control circuit characterized by a cutoff frequency much greater than a frequency of a voltage ripple on a bus voltage of the ballast circuit. The dimmable ballast circuit may also comprise a non-linear amplifier circuit amplifying a lamp-current-feedback signal representative of the magnitude of the lamp current through the lamp.

Use of Demand Response (DR) and Distributed Energy Resources (DER) to mitigate the impact of Variable Energy Resources (VER) in Power System Operation

A system and process / method of modeling demand-response (DR) and distributed-energy resource (DER) assets is provided, facilitating the aggregation of said assets in virtual power plants (VPPs), and using VPPs to provide energy balancing services needed to minimize the impact of Variable Energy Resources (VER) on power system. The method accurately accounts for assets by qualifying assets based on various parameters and by forecasting the capabilities of the resulting VPPs for provision of balancing services. Asset performance factors that may affect the aggregated VPP's capabilities are monitored and recalculated when necessary. Near-term forecasted VPP capability is compared to near-term forecasted imbalances in the electric-power-supply system, and the VPP is dispatched to minimize the system imbalances. The dispatch signal is disaggregated to control commands to individual assets. This process provides a reliable and cost effective approach to support higher penetrations of renewable generation in the electric power system.

Differential pressure gauge for cryogenic fluids which selects a density value based on pressure measurement

A differential pressure gauge for a cryogenic storage tank provides onboard entry, by an operator, of tank dimensions, tank orientation stratification coefficient, and the type of liquid stored within the tank. A differential pressure sensor supplies a signal corresponding to a differential pressure. A pressure sensor supplies a signal corresponding to the head pressure. The gauge uses the information supplied by an operator, combined with stored formulas and liquid characteristics, to perform real-time liquid volume computations. The liquid volume may be displayed on the gauge itself or may be transmitted via telemetry to an external device.

A method and system for supply voltage regulation in a motor circuit protector (MCP) that includes a current transformer coupled to a rectifier and a stored energy circuit. A solenoid is actuated by that circuit when a sufficient voltage is present. A controller having a configurable input is coupled to the stored energy circuit. Upon startup of the motor circuit protector, the controller causes the stored energy circuit to be charged to a startup voltage level via secondary current from the current transformer. The controller periodically interrupts the charging to measure the secondary current to detect fault levels. During startup, the configurable input is set to a comparator input for rapid current measurements. During run mode, the configurable input is set to an A / D input for accurate measurements. The controller measures the voltage of the stored energy circuit while charging it to a power level sufficient to actuate the solenoid.

Converter and inverter including converter circuit

In an inverter comprising a converter circuit that converts an alternating current into a direct current and an inverter circuit that inverts the direct current into the alternating current, supply of energy from a voltage smoothing capacitor to a load or recovery of energy from the load is facilitated without the necessity of increasing the capacitance of the voltage smoothing capacitor interposed between the converter circuit and inverter circuit. In the converter circuit, before the supply of energy to the load is started, the voltage on a dc link is raised. Before collection of energy from the load is started, the voltage on the dc link is lowered.

Manufacturing method for semiconductor device

A manufacturing method includes the step of laminating a sheet assembly onto chips arranged on a processing tape, where the sheet assembly has a multilayer structure including a base and a sinter-bonding sheet and is laminated so that the sinter-bonding sheet faces the chips, and subsequently removing the base B from the sinter-bonding sheet. The chips on the processing tape are picked up each with a portion of the sinter-bonding sheet adhering to the chip, to give sinter-bonding material layer-associated chips. The sinter-bonding material layer-associated chips are temporarily secured through the sinter-bonding material layer to a substrate. The sinter-bonding material layers lying between the temporarily secured chips and the substrate are converted through a heating process into sintered layers, to bond the chips to the substrate. The semiconductor device manufacturing method is suitable for efficiently supplying a sinter-bonding material to semiconductor chips while reducing loses of the sinter-bonding material.

An elongated movable contact arm (18) is cantilever mounted at one end in the recess and mounts a second movable contact (18a) on a free end of the arm which is adapted to move into and out of engagement with the stationary contact. A heater (20) is mounted in the recess in heat transfer relation with a snap acting thermostatic disc (22) disposed adjacent to the movable contact arm so that upon reaching a preselected temperature the disc will snap from one dished configuration to an opposite dished configuration with its motion transferred to the movable contact arm to move the contacts out of engagement. The cover is formed with a first multiple wall barrier (122) in the form of a triangular body when seen in a lateral cross section closing a first terminal receiving opening and a second multiple wall barrier (124) closing a second terminal receiving opening to interrupt the travel of arcs and the inlet of explosive gas to the enclosure.
