A fire sprinkler of the preferred embodiments includes a frame, a trigger, and a deflector. The frame defines a duct to exhaust the flow of a fire suppressing or extinguishing substance, and includes a fastener to fasten the frame to a supply line. The trigger blocks the flow of the fire suppressing or extinguishing substance through the duct during a first mode, and permits the flow of the fire suppressing or extinguishing substance during a second mode. The deflector redirects the flow of the fire suppressing or extinguishing substance into a coverage area. The deflector also at least partially shields the trigger from the dispersal of a fire suppressing or extinguishing substance from an adjacent fire sprinkler and prevents a failure of the trigger.

A system for generating, delivering and distributing electrical power to network elements over a data communication network infrastructure within a building, campus or enterprise. Consolidating power distribution and data communications over a single network simplifies and reduces the cost of network element installation and provides a means of supplying uninterrupted or backup power to critical network devices in the event of a power failure. The invention includes power / data combiners that combine a data communication signal with a low frequency power signal. The combined signal is transported over the LAN infrastructure where a power / data splitter extracts the data signal and the power signal and generates two separate outputs. The power over LAN system of the present invention operates with high bandwidth data communication networks, i.e., 10 Mbps, 100 Mbps, 1000 Mbps. The electrical power distributed over the LAN can be delivered as DC or low frequency AC voltages which in either case will not interfere with data communications signals. The electrical power delivered over data communications cable can be transmitted using one or more spare pairs in the cable or over the receive and transmit wires.

An image capturing device employing as illumination source(s) (flash apparatus(es)) a plurality of light emitting diodes emitting light of different colors; wherein such light emitting diodes are respectively made to emit light in pulsed fashion in turn by emitted color during exposure time(s). Furthermore, during exposure time(s), such light emitting diodes may be made to sequentially emit light in pulsed fashion in turn by emitted color, and / or such light emitting diodes may be made to sequentially emit light in pulsed fashion in turn by emitted color over multiple iterations.

Power supply response to variations in power demand by a microprocessor is improved with a compensation loops that estimate changes in load current with improved speed. The load current estimate is performed in part with a capacitance feed forward compensation loop that senses voltage at output capacitors to replicate the current present in the capacitors and communicates the capacitor current adjusted by an optimized gain to the power supply for adjustment of power output. Capacitor current is replicated with a frequency domain filter having a pole that cancels out the zero created by power supply equivalent series resistance and capacitor capacitance. The capacitance compensation loop improves power supply response time to microprocessor power demand skews so that the size or number of output capacitors may be reduced while still maintaining power supply at the microprocessor to within desired voltage and current tolerances.

Provided is an image display apparatus including: a vacuum container having an electron source enclosed therein for displaying an image; an ion pump communicating with the vacuum container for discharging air therefrom and decreasing pressure therein; and a resistor connected in series with the ion pump with respect to a power supply for driving the ion pump. Even if internal resistance of the ion pump undergoes order-of-magnitude changes according to its operating state, current consumption can be suppressed and the ion pump can be driven efficiently.

The invention relates to a pressure boosting system for at least one fuel injector of a high pressure injection system of an internal combustion engine, having a hydraulic pressure booster that is actuated by a control valve. The hydraulic pressure booster is configured with a pressure boosting piston, which comprises a first pressure booster piston part having a first diameter and a second pressure booster piston part having a second diameter, wherein the first diameter is greater than the second diameter. The pressure booster piston is disposed within a hydraulic reservoir chamber, onto which pressure is applied, together with the first pressure booster piston part having the greater diameter, wherein the accumulator chamber in turn is configured within a base body. The base body has a piston guide body for at least one of the pressure booster piston parts. The piston guide body is at least partially surrounded by an annular space, which is part of the hydraulic accumulator chamber.

A method of reducing drip from a nozzle mounted to a generally horizontally oriented supply conduit comprises reducing the amount of air remaining in the supply conduit when the nozzles are spraying liquid. Conveniently the amount of air remaining in the supply conduit can be reduced by drawing liquid from an upper portion of the supply conduit to supply the nozzle. An apparatus for practicing the method comprises a nozzle secured at the output end of a nozzle conduit wherein the input end of the nozzle conduit is located in an upper portion of the supply conduit.

A method for operating an internal combustion engine (1), especially of a motor vehicle, is described. Air and fuel are supplied to a combustion chamber (4) of the internal combustion engine (1) and exhaust gas is recirculated to the combustion chamber (4). The exhaust gas is recirculated to the combustion chamber (4) during overrun operation of the internal combustion engine (1).
