Abstract: A method for evaluating a weld in a formed object includes performing a contact mechanics test of a first region that includes the weld and storing one or more corresponding weld surface mechanical property measurements, performing a contact mechanics test of a second region that excludes the weld and storing one or more corresponding base material surface mechanical property measurements, determining a relative difference in the weld surface mechanical property measurements and the base material surface mechanical property measurements, determining one or more weld width measurements on the exterior surface of the formed object, and evaluating the weld based on the determined relative difference in the weld surface mechanical property measurements and the base material surface mechanical property measurements in relation to the determined weld width measurements in order to provide an index of weld quality that is traditionally measured through a destructive test or examination.

Abstract: A deployment module according to the present application enables both compact stowage of a sensor array and expansion of the sensor array into a three-dimensional volumetric array shape that enables improved directionality of the sensors during operation. The deployment module includes a support shell that is configured to retain a cable of the sensor array separately from sensors of the sensor array and an expandable deployment body formed of a superelastic shape memory alloy that uses superelasticity and stored energy for deployment of the sensor array. During deployment, the deployment body is removed from the support shell and the sensors are subsequently pulled out of the support shell. The deployment body then expands and holds the cable to retain the three-dimensional volumetric shape of the deployed array.

Abstract: A packing module includes a volumetrically efficient structure for separately retaining sensors and a cable of a sensor array. The packing module includes a tray that supports the sensors and a retaining leaf arrangement that extends outwardly from the tray to retain the cable on the tray. The retaining leaf arrangement includes a plurality of nested leaves that are spaced relative to each other. Packing the module includes placing the sensors separately and in succession on the tray and inserting a portion of the cable in the retaining leaf arrangement in between each placing of a sensor. The placement of a sensor and insertion of a portion of the cable occurs alternately until the entire sensor array is accommodated. Deployment of the sensor array may occur by alternately removing a sensor and a portion of the cable until the sensor array is displaced from the module.

Abstract: An apparatus includes a strain relief formed in helical shape and formed with a U-shaped channel. The strain relief can be used around a cable of a component or a spool extension of a fiber tray.

Abstract: Improved battery systems, apparatuses, and methods for use in electric air, land, and marine vehicles and mobile, portable, and stationary electrical appliances and devices are provided. The systems employ acoustic and current manipulation of anode interface deposits including dendrites on or proximate lithium and other anodes. This invention may employ multistatic ultrasonic phased arrays and current modulation to 1) minimize deposit, e.g., dendrite, initiation and formation by acoustic stirring, 2) acoustically image dendritic growths to monitor changes in dendrite growths, 3) cue dendrite cleaning and battery shutdown to avoid short circuit, 4) induce failure in dendritic structure and shearing of at least a portion of the dendrite from the anode, and 5) transport sheared dendrites and other dead metal to a graveyard.

Abstract: An apparatus for performing a contact mechanics test in a substrate includes a stylus having at least two contact elements. Each contact element has a contact profile, and the contact elements are disposed in the stylus to define a stretch passage therebetween. The stylus is configured to deform the substrate so as to cause the substrate to flow between the contact elements and induce tension in the substrate in order to generate and preserve micromodifications in the substrate. Methods of performing a contact mechanics test using the apparatus are also provided.

Abstract: An armrest assembly is disclosed herein. The armrest assembly includes a main body with a proximal adjustment assembly disposed at a first end and a distal adjustment assembly disposed at a second end. The proximal adjustment assembly provides for adjustment of the main body about a first axis. The distal adjustment assembly provides for adjustment of an arm pad about a second axis as well as a third axis. To prevent damage, a breakaway assembly is provided by the distal adjustment assembly to unlock the arm pad from a raised position and lower it into a lower position in the event a weight applied to the arm pad is beyond a particular weight threshold.
