摘要:
A method of extracting significant phrases from one or more documents stored in a computer-readable medium. A sequence of words is read from the one or more documents and a score is determined for each word in the sequence based on the length of the word. The score for each word in the sequence is compared against a threshold score. The sequence of words is indicated to be a significant phrase if the number of words in the sequences that have a score greater than the threshold score equals or exceeds a predetermined number. A sentence containing the sequence of words is retrieved from the document, if the sequence of words is a significant phrase. An abstract of the document is searched to determine if the sentence has been previously included in the abstract. If not, the sentence is added to the abstract.

Drive circuit and method for a gated semiconductor switching device A drive circuit and method for a gated semiconductor switching device (10) comprising providing coupling such as a mutual inductance between a gate drive circuit (21) for the device and a drain to source current supply circuit (22) for the device in order to change a gate voltage provided by the gate drive circuit dependent on a rate of change of a current in the drain to source current supply circuit. The change in gate voltage has a magnitude and phase arranged to increase or decrease a switching speed of the gated semiconductor switching device.

There is provided an improved roof solar panel, embodying a photovoltaic panel mounted on a frame for easy installation onto a conventional sloped roof and integration with conventional roof coverings. Such panel includes a roof covering mounting surface on an outside support of the frame, a photovoltaic panel mounting surface on an inside support of the frame, and when installed on the roof, a retainer trim for securing the roof covering and photovoltaic panel mounted on said supports while mounting to the frame. The frame also serves to provide means for securing the panel onto roof trusses. Integration with the conventional roof covering provides, inter alia, an attractive low profile with improved water shedding, wind resistance, and thermal regulation properties. The invention also relates to a kit comprising, inter alia, said roof solar panel, and to a method of installing said roof solar panel.

A bed for use with two adjacent seats separated from each other so that a gap is defined therebetween, which may include adjacent seats within or outside of a vehicle. The bed comprises a body comprising a first end disposed on one of the passenger seats and a second end disposed on the other seat. The body bridges the gap defined between the seats. The bed may further include means for securing the body into a position relative to the seats, and/or means for securing the body about the back of at least one seat.

The invention relates to systems and methods that improve distribution of fuel cartridges. The cartridges include compatibility information. A controller on the device validates the compatibility information before permitting fuel provision from the cartridge to the device. Invalid compatibility information, or absence of the compatibility information, then denies fuel flow to the device. This permits the device to validate that the cartridge and its contents are acceptable. This improves distribution by allowing the device or fuel cell manufacturer to implement cartridge selectivity by permitting cartridges from select manufacturers to provide fuel and denying cartridge of other manufacturers from providing fuel. Compatibility information stored in the cartridge memory may also be encrypted to prevent open access to the compatibility information. The compatibility information also improves fuel refilling distribution. In this case, the compatibility information permits a cartridge or device manufacturer to selectively control who can refill their cartridges.

An event materials organizer is provided. The organizer includes a panel having a first notch capable of supporting a necklace and a second notch capable of supporting a holder attachment. The first notch and the second notch extend from a first edge of the panel. The panel has a second edge wherein the second edge of the panel is opposite and parallel to the first edge of the panel. A third notch capable of supporting a necklace and a fourth notch capable of supporting a holder attachment may extend from the second edge of the panel. The panel may further include a first slit capable of supporting an item wherein the first slit is cut through the face of the panel. The panel may further include a second slit capable of supporting an item wherein the second slit is cut through the face of the panel.

A pulse generator comprises a capacitor, means for periodically discharging the capacitor to generate pulses of electricity and means for recharging the capacitor between pulses. Means is included for sensing a residual reverse polarity charge on the capacitor after generation of a pulse and for using the energy stored in it to assist in recharging the capacitor for the next pulse.

A fire hose coupling, such as a quarter-turn Storz-style coupling, comprises a substantially annular body having a first end connected to a fire hose and a second end having internal engagement lugs for connecting to lugs on another coupling. The coupling includes at least one locking lever movable between an unlocked position and a locked position, the lever locking the annular body of the coupling to the other coupling. The one or more locking levers comprise a light-reflecting surface to improve visibility of the lever. This facilitates assembly and disassembly of the couplings in conditions of poor visibility.
摘要:
A kick plate for a base bracket of a shelving unit, comprising an elongated panel having longitudinal and vertical axes, and an imaginary plane substantially coincident with the panel, and a substantially L-shaped member projecting from an end of the panel and integral with the panel, the L-shaped member having a longitudinal axis substantially parallel to the panel vertical axis, the L-shaped member further having a distal end extending further from the plane than the horizontal surfaces past the nominal width of the panel, wherein the distal end has a lip, wherein the lip removably attaches the panel to the shelving unit after the L-shaped member is inserted into the base bracket of the shelving unit, wherein the panel is removably attachable to the base bracket.
