Abstract: Control systems for liquid lenses can use feedback control using one or more measured parameters indicative of a position of the fluid interface in the liquid lens. Capacitance between a fluid and an electrode in the liquid lens can vary depending on the position of the fluid interface. Current mirrors can be used for making measurements indicative of the capacitance and/or the fluid interface position. The liquid lens can be calibrated using the measurements indicative of capacitance and/or fluid interface position as the voltage is driven across an operational range. A control system can use pulse width modulation (PWM) for driving a liquid lens, and a carrier frequency for the PWM signals can be varied to control power consumption in the liquid lens. The slew rate can be adjustable to control power consumption in the liquid lens.

Abstract: Sheets having thicknesses of from 1000 to 10,000 microns which are useful for the production of thermoformed semi-crystalline articles are based on polyaryletherketones having viscosities at 360° C. of at least about 400 Pas at 100 s?1 as measured by parallel plate rheometer. The polyaryletherketones are in a pseudo-amorphous state in the thermoformable sheets.

Abstract: A liquid lens can be coupled to ground, such as to impede charge from building up in the liquid lens during operation thereof. For example, an electrode that is in electrical communication with a conductive fluid of the liquid lens can be coupled to ground. A switch can be used to selectively couple the liquid lens to ground, such as for discharging the liquid lens. An electrode can be selectively coupled to ground and to driving signals using a switch. In some cases, drive signals can be provided to electrodes other than the grounded electrode for driving the liquid lens. In some cases, the liquid lens can be driven using feedback control based on one or more measured parameters indicative capacitance between a fluid and one or more electrodes in the liquid lens.

Abstract: A hanger clip is disclosed comprising: a housing and a clip member for attaching the hanger to a surface or protrusion. The clip member is connected to the housing and comprises a follower, wherein the clip member is configured to move between an open configuration and a closed configuration based on the position of the follower. The housing and clip are configured to receive a cam member which is configured to rotate within the housing to change the position of the follower to move the clip member between an open configuration and a closed configuration. The hanger clip can therefore be remotely actuatable using a tool attached to a pole which can be manipulated from ground level.

Abstract: Apparatus and methods of measuring the level of materials within a sand separator are disclosed. Embodiments include mounting the source and detector on an expandable band to facilitate moving the detector between separators, and embodiments in which the detector is configured to provide a response when the level exceeds a threshold level. The response may include an audio-visual alert or controlling dumping of sand from the separator.

Abstract: A method for separating solid and liquid components from gas components in a hydrocarbon production stream. The method includes the steps of: conveying the production stream into a cylindrical vessel having an inner cavity; creating an initial drop in velocity of the production stream; directing the production stream to flow around the inner cavity; collecting the gas components from the production stream at a top end of the vessel; and collecting the solid and liquid components at a drain in a bottom end of the vessel.

Abstract: An apparatus and method for separating a natural gas production stream from hydrocarbon well operations into a gas component and a sand and liquid component is described. More specifically, a sand separator comprising a cylindrical body, a production stream inlet port, a gas outlet port and a solid and liquid drain port is described. The cylindrical body has an inner cavity with an inner cone having one-way gas vents and a stationary auger wrapped around the inner cone. The production stream inlet port includes a pipe having a curved tip that directs the production stream into the body and around the inner cone and stationary auger, causing the production stream to slow down and the components to separate.

Abstract: A collapsible bladder system for the storage and disposal or re-use of cement returns from oil and gas wells is described. The collapsible bladder system includes a flexible storage bag having an input valve, an output valve and a vent that can be easily set up and transported by a single person. Cement returns are pumped into the flexible storage bag and allowed to harden into a cement block. The cement block covered with the storage bag can be hauled away for disposal or re-used for a secondary purpose, such as a barricade.

Abstract: A computer controlled roll-forming apparatus is adapted to provide a repeating pattern of different longitudinal shapes to a continuous beam “on the fly” during the roll-forming process. A sweep station on the apparatus includes a primary bending roller tangentially engaging the continuous beam along the line level and an armature for biasing the continuous beam against the primary bending roller for a distance partially around a downstream side of the primary bending roller to form a sweep. Further, actuators adjustably move the armature at least partially around the downstream side of the primary bending roller between at least first and second positions for imparting multiple different longitudinal shapes into the continuous beam. In one form, the apparatus also includes a coordinated cut-off, so that when separated into bumper beam segments, the ends of the individual beam segments have a greater sweep than their center sections.
