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 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.

An RF generator power supply comprises a first switched mode power supply (SMPS) connected in series to a second SMPS by a DC bus. A capacitor is arranged between the outputs of the first SMPS and inputs of the second SMPS to act as a smoothing capacitor for the first SMPS and to supply pulse energy to the second SMPS. The second SMPS has an output connected to an input of a step-up transformer and an output of the step-up transformer is connected to an input of a rectifier connectable to the RF generator. An input of the first SMPS is connectable to a prime power supply to maintain a high power factor with low harmonic content while setting an operating voltage and peak current level for the RF generator. The second SMPS is arranged to feed the step-up transformer and is arranged to operate with a variable duty cycle and/or variable frequency to provide average power control of the RF generator. The second SMPS is rapidly switched off on detection of a power surge through the RF generator.
