A non-invasive tension measuring system is provided with at least one pair of sensors positioned longitudinally and at a predetermined distance from each other along a linear system. At least one operationally connected processor executes instructions to detect, using the sensors, a transverse wave propagating along the linear system in order to determine a time delay of the transverse wave, to determine a propagation speed of the transverse wave based on the time delay, and to determine a tension of the unit length of the linear system based at least in part on the propagation speed and a mass per the unit length of the linear system.

A twistless cable deployment apparatus is provided for deploying cable. The apparatus includes a level winder that can be joined to a winch. The level winder is in a fixed position relative to the cable winch. The level winder has a non-rotating fixed spool that stores the cable by wrapping the cable around the spool. A rotating base is disposed coaxially with the fixed spool and rotates around the axis of the fixed spool. A post is mounted on the rotating base, and a traveler is slidably mounted on the post. A traveling guide eye is joined to the traveler. By rotation of the rotating base, cable is deployed from the fixed spool. A primary guide eye can guide the cable to the winch.

A tension sensor includes a planar tab having a first and second side, first and second end sections and an aperture through each of the end sections. A first strain gage is attached to the first side of the tab. The first strain gage has a tension grid aligned to a longitudinal axis of the tab and a cross-tension grid perpendicular to the tension grid. A second strain gage is attached to the second side of the tab. The second strain gage has a tension grid aligned to the longitudinal axis of the tab and a cross-tension grid perpendicular to the tension grid. The first strain gage and second strain gage are wired in a Wheatstone bridge in which the tension grid and the cross-tension grid of the first strain gage form one side and the tension grid and the cross-tension grid of the second strain gage form another side.

A cable tray and method of use is provided with the cable tray having a bottom extending along a horizontal panel with two opposite side edges. A pair of side walls attaches to the two opposite side edges. A first positioning rack extends between the side walls. The first positioning rack is orthogonal to the tray bottom and the side walls. A second positioning rack extends between the side walls. The second positioning rack is orthogonal to the tray bottom and the side walls. A first foot bar affixes to an underside of the tray bottom. The first foot bar is vertically aligns with the first positioning rack. A second foot bar affixes to the underside of the tray bottom. The second foot bar vertically aligns with the second positioning rack. Each of the first positioning rack and second positioning rack includes cable support apertures.

Compact stackable trays with positioning racks

A strength member sewing machine is provided which comprises upper and lower feeder spools, a collection spool and idlers positioned on a support structure. A cord supply, a fabric shaper, a speed control and a pressure foot lift are positioned on the structure. Fabric from the spools is kept in tension with the idlers while moving toward the fabric shaper. The fabric from the upper spool is crimped while the fabric from the lower spool remains flat underneath the shaper. Between the fabric layers, pull cords are pulled through from the cord supply thru the fabric shaper. The fabric with crimps and with the pull cords inside the crimps is sewn to the fabric from the lower spool to create casings with a pull cord in the internal space of each casing. The joined fabrics with the pull cords are collected by the collection spool as a finished product.
