Abstract: Some embodiments relate to methods and systems for gaming monitoring. An example method comprises: receiving by a computing device a series of images and timestamp information of a capture time of each image in the series of images, wherein each image of the series of images is an image of a gaming environment; processing by the computing device a first image in the series of images to determine an event trigger indicator in the first image; identifying a gaming monitoring event based on the determined event trigger indicator; transmitting image data of the first image and images proximate to the first image in the series of images to an upstream computing device; wherein determining the event trigger indicator comprises detection of a first game object in the first image, wherein the first game object was not detected in an image captured prior to the first image in the series of images.

Abstract: An apparatus (100) for mixing a liquid (160) containing particulates (106, 108) comprising: a vessel (102) for containing the liquid (160) with a sidewall (120) and bottom (124); an impeller (300) rotates about a substantially vertical axis (X-X), the impeller submerging below the liquid surface (162) by a distance approximately one-tenth to one-half of the liquid (129) height; at least two spaced apart blades (310) extending radially outwardly of the vertical axis, the blades including back-swept blades pitched substantially parallel to the vertical axis, at least 50% of the length of each blade comprising an angled section (312) extending through a chord angle of 20 to 60 degrees to produce: an inner, upward flow region (164) along said vertical axis, a transition flow region (166) around the impeller in which liquid moves radially outwardly toward the vessel sidewall, and an outer, downward flow region (168) along the sidewall.

Abstract: A device for reducing friction of a viscous fluid flow in a conduit is disclosed. The device comprises a body positionable to define at least a segment of a flow path for the viscous fluid in or contiguous with the conduit, a cavity in the body for retaining lubricating fluid, and at least one port in the body for delivering lubricating fluid to the cavity. A fluid outlet arrangement from said cavity delivers lubricating fluid to the flow path to form a downstream lubricating film at the conduit surface. The fluid outlet arrangement comprises a substantially continuous opening or ring of close spaced openings, effective collectively to reduce the pressure variation and therefore velocity variation of the delivered lubricating fluid along said outlet arrangement.

Abstract: There is disclosed a device for improving flow of a viscous fluid in a fluid transport conduit, the device comprising: a porous conduit having a passage through which the viscous fluid may pass between upstream and downstream sections of the fluid transport conduit; and a casing member having a wall which extends around the porous conduit, the device being configured such that, when it is in situ, a fluid transfer chamber having at least one fluid inlet is defined between the casing member wall and porous conduit, whereby lubricating fluid may pass under pressure through the inlet(s) into the fluid transfer chamber and through the porous conduit into the passage to lubricate the flow.

Abstract: A device for reducing friction of a viscous fluid flow in a conduit includes a body (10,110) positionable to define at least a segment of a flow path for the viscous fluid in or contiguous with the conduit, a cavity (40,140) in the body for retaining lubricating fluid, and at least one port (42,142) in the body for delivering lubricating fluid to the cavity. A fluid outlet arrangement (48,148) from the cavity delivers lubricating fluid to the flow path to form a downstream lubricating film about viscous fluid flowing therein. The fluid outlet arrangement comprises a substantially continuous opening or ring of close spaced openings about the flow path. The cavity comprises an array of passages in the body that includes a plurality of elongate passages (55,155) that extend about the flow path effective collectively to reduce the pressure variation and therefore velocity variation of the delivered lubricating fluid along the outlet arrangement. A corresponding method is also disclosed.
