    Abstract: A tube fitting for connection to a tube includes a main body structure and a tube liner. The main body structure is configured to receive an end of the tube and fluidly connect the tube to another component. The tube liner is positioned at least partially within the main body structure and is configured to extend into the tube. The main body structure and the tube liner are configured such that, when the tube is fully inserted into the tube fitting, the end of the tube is positioned at a predetermined depth within the tube fitting, and the main body structure and the tube liner cooperate together to provide an audible indication to indicate that the tube has been fully inserted into the tube fitting.

    Abstract: A bracket holds a rigid or flexible tube during the pouring of a concrete slab. The bracket has a base and a housing connected to the base. The tube curves around a first tube support on the housing before passing through an opening in the bottom of the housing. The tube and any members inside the tube are cut off so they end inside the housing and are then covered by a housing cap. The base is fastened to a form for the concrete slab. The height of the housing relative to the base is adjusted to place the cap at the planned surface of the concrete slab. After the concrete slab is formed the cap is removed and the cut members inside the housing are connected to other members or devices.

    Abstract: An improved cap and assembly is provided for a poured concrete deck. The improved assembly has a diaphragm seal over-molded to a top plate having a depending sidewall that is snap-fit to a base containing a fire ring. A tubular sleeve is connected to the over-molded top plate by snap fit connections to the sidewall and by threaded fasteners passing through sockets in the sleeve, sidewall and base. The over-molded diaphragm has a funnel shape. A first sleeve cap has depending positioning tabs that may be broken off to adjust the cap height relative to the sleeve, with an inwardly extending latching surface engaging the sleeve when the tabs are removed. A second cap has inwardly extending tabs that fit into channels on the sleeve fit between ridges on the sleeve when rotated to adjustably position the second cap on the sleeve.

    Abstract: A connector for a fluid line includes a sleeve having a hollow portion at least partway therethrough. The sleeve includes an engaging portion. A collet having an engaging part is secured to the engaging portion. A grab part has one or more teeth configured to retain the fluid line, and the teeth are located in the hollow portion. A locking part is provided having a locking portion, and the locking part is configured to move from a first position to a second position where the locking portion locks with a locking piece to assist with forming a fluid seal with the fluid line.

    Abstract: A valve assembly includes a body having a fluid inlet disposed on a first end of the body and a fluid outlet disposed on a second end of the body in fluid connection with the fluid inlet. The valve assembly further includes a push-to-connect fitting which is integral to the body and configured to connect to an end of a pipe, a stem configured to seal the body in a first position and configured to allow fluid to flow from the fluid inlet of the body to the fluid outlet in a second position, and a connector surrounding at least part of the push-to-connect fitting. The body is configured to house a sealing ring. The push-to-connect fitting is configured to communicate the fluid inlet with the end of the pipe. The sealing ring secured by the push-to-connect fitting is configured to provide a seal between the fluid inlet and the end of the pipe.

    Abstract: A fluid flow meter system for monitoring fluid flow through a lumen includes a first ultrasonic transducer configured to transmit one or more versions of a transmit (TX) signal through a fluid flowing within the lumen, and a second ultrasonic transducer configured to receive one or more respective receive (RX) signals. The fluid flow meter system includes an analog-to-digital converter (ADC) configured to sample, at a first frequency, the one or more RX ultrasonic signals and a processor configured to generate a fine resolution signal based on the one or more RX ultrasonic signals. The fine resolution signal is associated with a second sampling rate higher than the first sampling rate. The processor is also configured to compute a cross-correlation signal indicative of cross-correlation between the fine resolution signal and a waveform and determine an estimated fluid flow parameter based on the computed cross-correlation signal.
