Abstract: A low-power wireless communication device is in a sleep or standby mode of operation for extended periods of time, periodically becoming fully operational and issuing a “check in” message to a base station, thereby inhibiting the ability of the base station to assist in the locating of device, and remotely updating the settings or operational programming of the device much of the time. Upon receipt of a command to locate a misplaced low-power wireless device or to update the device, a base station queues an associated command in a task queue. Upon receipt of a check-in message from an associated low-power wireless device, indicating it is in a fully powered and communicative state of operation, the base station searches its task queue for applicable commands relative to the specific wireless device and executes them via communication with the now fully-operational wireless device.

Abstract: An apparatus including a fairing operable to suppress a vortex-induced vibration of a tubular, the fairing having a body portion and a tail portion that tapers from the body portion to an end portion, the body portion defining an annulus dimensioned to encircle a tubular. The apparatus further including a stabilizing member positioned along the body portion, the stabilizing member being dimensioned to stabilize the fairing along a tubular positioned within the annulus.

Abstract: An apparatus including a fairing having a tail portion and an end portion capable of suppressing a vortex-induced vibration of a tubular. The apparatus further including a stabilizing member attached to the end portion of the fairing, the stabilizing member dimensioned to increase a thickness of the end portion of the fairing and a flange member attached to the stabilizing member, the flange member dimensioned to increase a chord dimension of the fairing so as to improve a stability of the fairing.

Abstract: An apparatus including a strake section having a plurality of helical fins separated by at least one helical opening. A method including forming a helically shaped fin that independently maintains the helical shape once formed.

Abstract: A sprung caster wheel assembly includes a base member supporting an object thereon and a swivel member mounted for rotation about a vertical swivel axis below the base member. Two spaced apart pivot arms are pivotally coupled to the swivel member for pivotal movement about a first lateral axis and rotatably support a wheel between the free ends thereof. The wheel rotates about a second lateral axis parallel to the first lateral axis and offset to one side of the vertical swivel axis. A torsion spring is helically wound about the first lateral axis and is coupled between the pivot arm and the swivel member to provide a sprung suspension to the base member supported above the wheel.
