A device, for trapping an item in an intake hose of a vacuum before the item reaches a collection bin of the vacuum, includes a body and a screen. The body has a chamber, an entrance, and an exit. The chamber is configured such that when the chamber is coupled to an intake hose of a vacuum and the vacuum draws fluid into the intake hose, the fluid flows through the chamber. The entrance is couplable with an intake hose of a vacuum and configured such that when fluid flows through the body's chamber, the fluid enters the chamber through the entrance. The exit is coupleable with the intake hose of a vacuum and configured such that when fluid flows through the body's chamber, the fluid leaves the chamber through the exit. The screen of the device is disposed inside the body's chamber, and sized and configured to allow fluid that the vacuum draws in to flow through the body's chamber while preventing large objects suspended in the fluid from flowing through the body's chamber.

A coaxial cable may include an inner conductor, an outer conductor coaxially disposed about the inner conductor, and a proximal end sized and shaped for insertion into a connector. The proximal end may have an outer conductor contact coupled electrically to the outer conductor, and an extended section of the inner conductor that extends axially beyond the outer conductor contact. The extended section may include an inner conductor contact having an electrically conductive material disposed at least partially around the inner conductor, and an insulated area positioned to isolate electrically the outer conductive contact from the inner conductive contact, and having an electrically insulating material disposed at least partially around the inner conductor.

The present invention relates to a method for merging regions in the image/video, capable of merging plural of image regions into an image merging region. In the disclosed method, these image regions are first sequenced basing on their compactness value. Then, one of these image regions is designated as a reference image region, and a merging test process is executed by merging the reference image region with one of the nearby image regions thereof in sequence, for forming a temporal image merging region. Later, the compactness value of the temporal image merging region is compared with the compactness value of the two consisting image regions thereof, respectively. When the compactness value of the temporal image merging region is larger than either one of the compactness value of the two consisting image regions thereof, the temporal image merging region is designated as an image merging region.

An expandable trailer that is easy to store and transport yet is still large enough for most applications. The expandable trailer is shiftable between a relatively compact, retracted configuration for easy storage and/or transport and a relatively larger, expanded configuration for use in hauling items. Improved structures and mechanisms for selectively shifting the trailer between the retracted and expanded configurations are also disclosed.

An exemplary welding nozzle has a smooth, highly polished bore of circular cross-section. The bore has a forward portion of generally flared, gradually curving shape, joined with a narrowing inner portion along a gradual curve. Hence a concentrated surface flow of shielding gas may be directed out the nozzle's mouth to reliably provide a flared shielding envelope having reinforced boundaries. The inner portion tapers inwardly at a constant angle for a length sufficient to dampen flow disturbances. Hence an inner core of shielding gas of high ionization potential may be directed in laminar flow out the nozzle's mouth for concentration immediately about the exposed electrode to stabilize the electric arc at the electrode tip. The diverging gas flows enable significantly reduced gas consumption while reliably maintaining weld quality, a reduced rate of spatter buildup within the nozzle, and increased versatility of welding tip operation in both automated and manual environments.

A firmware bundle is download to a non-operational storage area without changing a live copy of firmware in a device. The firmware bundle is downloaded in order to reboot the device to deploy one or more downloaded firmware packages from the non-operational storage area to the device, launch an Early Boot Installer manager to spawn and monitor the status of one or more Early Boot Installer processes contained in the firmware bundle download, determine in parallel whether a firmware install to one or more subsystems of the device is desire, and install the downloaded firmware package in parallel to one or more subsystems of the device.
摘要:
A gypsum slurry is described that includes water, a hydraulic component comprising at least 50% calcined gypsum by weight based on the dry weight of the hydraulic component, foam, a defoamer and a polycarboxylate dispersant. In some embodiments of the invention, the defoamer is combined with the dispersant prior to being added to the gypsum slurry. The defoamer and dispersant can be added as a physical mixture, wherein the defoamer is attached onto the dispersant polymer, or a combination thereof. In some embodiments, a gypsum building panel is made from the gypsum slurry.
