Abstract: An apparatus and method for controlling a DC-to-AC inverter is disclosed. The DC-to-AC inverter may be configured to convert DC power received from an alternative energy source to AC power for supplying an AC grid or load. The inverter may determine whether the power presently supplied by the alternative energy source is less than a predetermined amount of power and, if so, disable an output converter of the inverter. Additionally, the inverter may predict the voltage of a DC bus of the inverter at a future point in time and, if the predicted DC bus voltage is greater than a predetermined maximum DC bus voltage, enable the output converter to transfer energy from the DC bus to the AC grid to reduce the DC bus voltage.

Abstract: An energy recovery circuit receives and stores energy associated with switching transitions in a power converter having a first switch and a second switch configured to be operated to selectively apply a voltage source to an output load. The energy recovery circuit includes an inductive element, a diode, and a capacitive element. The inductive element receives at least a portion of electrical current flowing through one of the first switch and the second switch. The at least a portion of the electrical current flows through the diode to charge the capacitive element with a voltage. The energy recovery circuit includes a recovery power converter to transfer the voltage from the capacitor.

Abstract: An apparatus and method for controlling the delivery of power from a DC source to an AC grid includes an inverter configured to deliver power from the unipolar input source to the AC grid and an inverter controller. The inverter includes an input converter, an active filter, and an output converter.

The output converter is configured to control the output converter to deliver power to the AC grid. Additionally, the active filter controller is configured to control the active filter to supply substantially all the power that is deliver by the output controller to the AC grid at a grid frequency.

Abstract: An inverter for converting an input direct current (DC) waveform from a DC source to an output alternating current (AC) waveform for delivery to an AC grid includes an input converter, an output converter, and an active filter, each of which is electrically coupled to a bus. The bus may be a DC bus or an AC bus. The input converter is configured to convert the input DC waveform to a DC or AC bus waveform. The output converter is configured to convert the bus waveform to the output AC waveform at a grid frequency. The active filter is configured to reduce a double-frequency ripple power of the bus waveform by supplying power to and absorbing power from the power bus.

Abstract: The invention provides a method for determining a degree of phosphorylation of a substrate, for example a peptide substrate, using a fluorescence probe that acts alone or with another material and has a lifetime that varies when in proximity to a phosphate, the method comprising: causing the fluorescence probe to fluoresce; measuring a time response of the fluorescence, and analysing the fluorescence time response to identify a fluorescence component having a lifetime associated with phosphorylated substrate and a fluorescence component having a lifetime associated with un-phosphorylated substrate.

Abstract: The present invention provides a method and a system for connecting together, in a VLSI chip, a plurality of macros which require data flow connections between each other. A simple standard interface is realised between all macros. Any number of macros can be connected together, also allowing concurrent transactions between 4 or more macros using a cross-bar switch. Each macro may be a master (capable of requesting connections), a slave (capable of receiving connections from a master) or both. The centralised inter-connect logic includes three major components: the cross-bar switch, which makes the connections between the macros, the address decoder, which determines which slave each master wishes to connect to and an arbiter, which arbitrates between the macros when two or more masters request a connection simultaneously.

Abstract: A cap for installation over the open end of a tubular member that has a pipe or pipes of smaller diameter projecting through the open end of the tubular member. The cap has a rubber discoid portion that covers the open end of the tubular member and a rubber apron extending from the discoid portion and adapted to encircle the tubular member adjacent to its open end. An aperture or apertures for the pipes of smaller diameter are provided in the discoid portion. The cap is split except at the back where a portion including the apron provides a hinge. The split intersects the aperture or apertures. A split, flexible metal band is embedded in the apron and has a latch for tightening and locking the apron about the tubular member. To install the cap, it is hinged open and placed over the end of the tubular member with the smaller diameter pipes passing through the apertures, and is then closed around the tubular member and locked.
