System and methods are disclosed for fluid measurements which may be utilized to determine mass flow rates such as instantaneous mass flow of a fluid stream. In a preferred embodiment, the present invention may be utilized to compare an input mass flow to an output mass flow of a drilling fluid circulation stream. In one embodiment, a fluid flow rate is determined by utilizing a microwave detector in combination with an acoustic sensor. The acoustic signal is utilized to eliminate 2pi phase ambiguities in a reflected microwave signal. In another embodiment, a fluid flow rate may be determined by detecting a phase shift of an acoustic signal across two different predetermined transmission paths. A fluid density may be determined by detecting a calibrated phase shift of an acoustic signal through the fluid. In another embodiment, a second acoustic signal may be transmitted through the fluid to define a particular 2pi phase range which defines the phase shift. The present invention may comprise multiple transmitters / receivers operating at different frequencies to measure instantaneous fuel levels of cryogenic fuels within containers positioned in zero or near zero gravity environments. In one embodiment, a moveable flexible collar of transmitter / receivers may be utilized to determine inhomogenuities within solid rocket fuel tubes.

An improved durable golf tee comprises a separate upper portion and a separate lower portion that are axially aligned and enclosed within a flexible collar. The upper portion has an upper end for supporting a golf ball, an upper shank and a lower end having an upper annular flange. The lower portion has a pointed lower end for inserting the tee into the ground, a lower shank and an upper end having a lower annular flange. The flexible collar encloses the lower end of the upper portion and the upper end of the lower portion, forming an integral golf tee, whereby the upper portion and the lower portion are independently flexible within the collar.In a second embodiment, the interior tee portions are molded as a single tee component having the upper portion and the lower portion interconnected by a reduced-diameter (break-away) center portion. The center portion and the respective inner ends of the upper and lower portions are enclosed within the flexible collar. Once the break-away center portion is fractured, the upper portion and the lower portion are independently flexible within the flexible collar.The durable golf tee is formed by a method including the steps of: molding the upper portion and lower portion of a strong, tough plastic (nylon) material; and over-molding the upper shank, upper flange, lower shank, and lower flange with a flexible (rubber) collar.

An inflatable evacuation slide system includes a slide pack that is ejected from its enclosure by means of an ejection bag, which inflates rapidly to force the evacuation slide out of the enclosure. The high accelerations imposed on the uninflated evacuation slide by the ejection bag make the slide prone to tearing on the edge of the fuselage as the slide pack is forced through the opening. Accordingly, the enclosure is provided with a chafing skirt, which comprises a flexible collar that deploys outward from the enclosure and lays flat against the aircraft fuselage to provide a smooth transition region between the enclosure and the aircraft skin.

A footwear upper having a collar assembly that is joined at its forward edge to the lower portion of the upper by a flexible region of material so that the collar may flex forward and rearward in relation to the lower portion of the upper. In one aspect of the invention, the upper includes a neck portion that is telescopically overlapped by the collar. In another aspect, the upper includes a gusset that extends between the lower portion and the collar, with at least a portion of the gusset being substantially hidden from view.

A universal adapter device facilitates transfer of liquid from a neck of a liquid dispenser to a receiving container. The device includes a hollow body. The hollow body includes a flexible liquid inlet with an inwardly sloping flexible collar, a liquid outlet, and a one-way valve for allowing air into the hollow body when a pressure within the hollow body is less than ambient pressure.

An ostomy coupling is disclosed comprising a floatable coupling part. The coupling part is supported with respect to an adhesive wafer by means of a flexible support collar that permits displacement of the coupling part in a floatable manner. The flexible collar comprises plastics film and has bistable shapes. The collar is configured to hold the coupling part stably in (i) an extended position spaced from the adhesive wafer, to facilitate an ostomate to manually brace the coupling part in order to relieve the attachment force when an ostomy appliance is press fitted to the coupling part, and (ii) in a retracted position close to the adhesive wafer.

An adapter is disclosed for an ostomy coupling. The adapter provides a floatable coupling characteristic to an ostomy body fitment that has a non-floatable coupling part. The adapter comprises a first coupling part for attaching to the non-floating coupling part of the body fitment, a second coupling part for releasably attaching to an ostomy appliance, and a flexible collar between the first and second coupling parts. The flexible collar permits the second coupling part to be displaced away from the first coupling part, thereby creating a space for an ostomate to manually brace the second coupling part against an attachment force when an appliance is fitted.

A neck support / brace for protecting a neck has a flexible collar with a top wall, bottom wall, sidewalls and sectional walls disposed therebetween that form compartments therein. A plurality of cells are disposed within the compartment. Each of the fluid cells have a valve element disposed therein. When the pressure acting upon the cells is below a threshold pressure, fluid or air flows through the valve element to allow movement of the neck. Alternatively when the pressure on the cells is above the threshold pressure the valve element closes preventing fluid or air flow out of the fluid cell thus causing the cell to stay inflated and provide resistance to a neck movement.
