Wind sensor devices, systems, and methods are provided in accordance with various embodiments. The wind sensor device may include: a first support ring; a second support ring; a first transducer coupled with the first support ring; a second transducer coupled with the first support ring; a third transducer coupled with the second support ring; and a fourth transducer coupled with the second support ring. A center of a face of the first transducer, a center of a face of the second transducer, a center of a face of the third transducer, and a center of a face of the fourth transducer may form four vertices of a tetrahedron, which may include an equilateral tetrahedron. The first transducer, the second transducer, the third transducer, and the fourth transducer are generally directed away from a center of the tetrahedron.

Methods, systems, and devices for acoustic structural reflection interference mitigation are provided in accordance with various embodiments. For example, some embodiments may provide for structural reflection interference mitigation for compact three-dimensional ultrasonic anemometers. Some embodiments include a method that may include transmitting a first acoustic signal from a first acoustic transmitter. At least a first portion of the first acoustic signal from the first acoustic transmitter may be hindered from being received at a first acoustic receiver. At least a second portion of the first acoustic signal from the first acoustic transmitter may be received at the first acoustic receiver along an acoustic propagation path. In some embodiments, the first acoustic transmitter may include a wide-beam transmitter. Some embodiments may utilize four wide-beam transducers positioned at apices of a tetrahedron.

Provided are holders for compactly storing infusion management systems to surfaces. In an embodiment the holder apparatus has a head portion for receiving and infusion management system trunk portion and a foot for receiving an apex portion of the infusion management system. The holder apparatus may be mounted to a wall so that the infusion management system is compactly stored and then mounted against the wall, thereby dramatically decreasing the storage footprint of the systems when not in use, without sacrificing the ability to conveniently and rapidly deploy the system when needed. Also provided are infusion management systems configured for use with the holder apparatus and related methods of storing the system.

A pipeline pig includes a venturi and a modulating valve located rearward of the inlet side of the venturi. When the valve is in the open position, a predetermined maximum bypass flow is allowed through the venturi. The closed position allows a predetermined minimum bypass flow. The valve may be a poppet-style valve or a frusto-conical shaped stopper. The stopper has sufficient mass and/or aerodynamic drag to overcome the spring force holding the valve in the open position. When the pig stalls, the valve closes and the stopper chokes bypass flow through the venturi. When the pig starts running again, the valve opens as inertia forces the stopper away from the inlet side of the venturi. Also, as friction of the pig increases due to changes in the internal diameter of the pipeline or accumulation of debris ahead of the pig, increased airflow across the valve creates drag sufficient to partially overcome the spring force, thus keeping the pig moving at a desirable rate of travel.

A bipolar electrosurgical instrument has a pair of pivotable juxtaposed jaw members and a locking mechanism operatively associated with a second of the jaw members. The locking mechanism has a first position engaged with the second jaw member for preventing movement of the second jaw member between an axially aligned orientation and at least one angled orientation, and a second position. The second position is disengaged from the second jaw member allowing for movement of the second jaw member between the axially aligned orientation and the at least one angled orientation. The instrument has an actuation mechanism operatively connected to a first of the jaw members with the actuation mechanism operable to move the first jaw member between an axially aligned first orientation and at least one angled orientation. An articulation knob is operatively associated with the locking mechanism and effectuates independent operation of the locking and actuation mechanisms.

A method for progressively dewatering a pipe or pipeline includes the use of a loose-fitting spherical- or quasi-spherical shaped pig body which rolls forward through the interior space of the pipe and temporarily captures and redistributes a portion of the volume of liquids available for capture and redistribution as the pig body rolls on past. Preferably, the portion captured is less than the volume available for capture. A part of the captured liquid may be redistributed to an upper quadrant of the pipe. Capture and redistribution are accomplished by way of a first bypass pathway and a second bypass pathway. One of the pathways may be a through-body pathway. The pig body may be a hollow pig body with a plurality of spaced-apart ports, a solid pig body with a plurality of paddle-like structures, or a cube-sphere type pig body with recessed external wall surfaces.

Progressive dewatering and inhibitor dispersal rolling pig

A method and system for launching a pipeline pig includes the steps of compressing a modulating bypass valve of a pipeline pig and installing a locking means to temporally maintain the bypass valve in the compressed state. Once the pig has travelled a predetermined distance through the pipeline, the locking means is released and retrieved through the launch trap door. The locking means is preferably a launching pin having a clip attachment that receives the clips of a retractable lead. The lead is housed by a retraction device that is detachably secured to the launch trap door. The modulating valve has sufficient mass and aerodynamic drag to overcome the force of a gas spring. The valve moves between a retracted and compressed position substantially instantaneously upon the pipeline pig stalling and between the compressed and retracted position substantially instantaneously upon the pipeline pig accelerating.
