A settling basin of a wastewater treatment system includes a collector chain including chain links having a plurality of side bars, stepped connecting pins configured to join the plurality of side bars and including a first end including a head portion having a cross-sectional area larger than portions of the plurality of side bars through which the stepped connecting pin extends, end caps configured to receive second ends of the stepped connecting pins, and apertures defined in the end caps and second ends of the stepped connecting pins configured to receive a retaining element that holds the end caps in position on the second ends of the stepped connecting pins.

Delivery devices and methods for delivering a stented prosthesis to a target site are disclosed. Disclosed delivery devices include a handle assembly including an actuator, an inner shaft assembly interconnected to the handle assembly, and are configured to releasably retain the stented prosthesis to the delivery device with at least one elongate tension member. The delivery devices further include a tension management device that is configured to limit the amount of tension that can be applied via the actuator to the at least one tension member. Certain embodiments are configured to apply different tension limits to different tension members that are controlled by a one or more actuators. Other various embodiments include one or more tension adjustors to selectively adjust one or more tension limits.

Systems and methods for measuring web tension distribution in roll-to-roll processes, for example, such as R2R processes employed in the fabrication of printed devices. Such systems and methods entail a web that travels between first and second rollers in a longitudinal direction of the web, inducing tension in the web in the longitudinal direction thereof such that tension is present in a flexible substrate of the web between the first and second rollers, and operating the system to determine an average tension and linear variation of tension present in the flexible substrate resulting from the tension induced in the web inducing a nonuniform tension distribution in the flexible substrate between the first and second rollers. The systems and methods utilize one or more devices that induce deflection in the web between the first and second rollers.

The tensile force sensor comprises at least one strain gauge in a tension piece comprising a central rectilinear segment and two folds at an angle, significantly thicker than the central rectilinear segment. The strain gauge is arranged in said central rectilinear segment in such a manner that a traction force on the fastening ends of the tension piece results in a U-shaped buckling of the central rectilinear segment. The invention also comprises a processing module connected to the strain gauge, adapted to detect and process as data the elastic deformations caused in the central rectilinear segment by the longitudinal stresses generated by traction on the fastening ends of the tension piece. The invention allows a portable and low cost wireless sensor to be produced.

A method includes providing a strap having a length enabled to encircle one side of a user's hand and tricep area when the user's elbow is bent at 90, and creating a loop with the strap. The loop closing with a buckle, and positioning the inside of one end of the loop around a ventral or dorsal portion of a user's hand or fingers. A step is provided for positioning the inside flat surface of a second end of the loop around at an area at a back side of the user's upper arm, above the elbow, with the elbow bent at approximately 90 degrees. The strap is then tightened to achieve an effective stretch as determined by the user and the stretch may be held for a determined amount of time thereby increasing strength and flexibility and lessen pain in the user's hand, wrist and forearm.

A sensor roller for determining planarity errors and/or for determining the tension of a strip tangentially engaging the roller has a roller body rotatable about an axis, having an outer surface, and formed with a plurality of radially outwardly open recesses axially spaced on the surface. Rigid sensor bodies each in a respective one of the recess each have an outer surface generally flush with the outer surface of the roller body. Each sensor body forms with a side surface of the respective recess a peripheral circumferentially fully extending gap. Respective force-measuring sensors in the recesses are each braced between a respective one of the sensor bodies and the roller body radially inward of the respective sensor body. An annular weld seam of welding compound is formed in each of the gaps

Disclosed is a method for assessing application and/or tightness of a cuff, comprising: determining a capacitance between a conducting component embedded in the cuff and earth, wherein the conducting component is electrically insulated from earth and from a patient; and determining application and/or tightness of the cuff based on the determined capacitance between the conducting component embedded in the cuff and earth.
