摘要:
A method for the startup of a solar power three-phase inverter in which a waiting period is increased between successive attempts to start the inverter. This method allows the inverter to start up in a reasonable amount of time while avoiding excessive cycling during prolonged periods of low light.

Disclosed herein is a grid interactive inverter capable of multiple modes of operation including: a normal mode for transferring DC power to a utility grid, a constant AC current mode for limiting inverter output, a constant DC voltage mode used for DC testing, and a PV array simulation mode for testing of other inverters in the manufacturing process.

A system and method are disclosed for automatically limiting the drainage of a bodily fluid such as cerebrospinal fluid (CSF) from a patient into a collection chamber. The collection chamber includes a vent having an hydrophobic filter for the passage of air to facilitate the movement of CSF yet to maintain a closed system. The system includes a buoyant float hingedly connected with the top of the collection chamber in one embodiment. When fluid rises in the collection chamber to a predetermined volume, buoyant force raises the float and causes a seal plug mounted on top of the float to seal one of an inflow port or a vent port. The float is limited to pivoting movement in one plane and to a certain angle within that plane. The system and method avoid overdrainage of CSF from the patient and overfilling of the collection chamber.

An blank firing attachment, with enhanced operating life, for use with gas-operated weapons; wherein, a tungsten carbide stem extending from the attachment is inserted into the bore of the weapon's barrel, the stem having a cross-sectional area less than the cross-sectional area of the bore, to provide backpressure within the barrel to properly cycle the weapon.

There is provided a system and method for ablating a surface of a work-piece comprising a radiation source for providing an ablating beam and a plurality of adjustable reflective masks having predetermined mask patterns thereon. The reflective masks are sequentially positioned relative to said radiation source and in the path of said ablating beam for reflecting said ablating beam onto the surface of the work-piece to ablate the work-piece.

A reciprocally-cycled weapon delinks and fires cartridges in open-end linked ammunition belts or close-end linked ammunition belts. The weapon has first round select and first cycle fire capabilities. The bolt carrier assembly translates out of phase with the extractor assembly. The extractor assembly is configured for rearward extraction of the cartridges in close-end linked ammunition belts. The weapon works seamlessly with open-end linked and close-end linked ammunition belts.

A reciprocally-cycled, externally-powered weapon may include a rotative driver connected via a crank and connecting rod to the operating group of the weapon. The connecting rod may be connected to a pinion that meshes with a translating rack and a stationary rack. The translating rack may be connected to the operating group, and the stationary rack may be fixed to the receiver of the weapon. The energy needed to fire the weapon may be supplied by an energy generator. The minimum amount of energy supplied by the energy generator may be independent of the speed of translation of the operating group and may be sufficient to reliably result in cartridge ignition, thereby providing an infinitely adjustable firing rate.
