Abstract: A line launcher includes a launcher body extending along a longitudinal axis between a rear end and a front end. The line launcher further includes a handle, a trigger, and a removable battery. The line launcher further includes a compressed gas charge assembly. The line launcher further includes an elongated barrel coupled to the body at the front end. The line launcher further includes a throwline assembly, the throwline assembly including a projectile and a throwline, the projectile insertable into and ejectable from the elongated barrel.

Abstract: A computer-implemented method and corresponding system perform generative design of an energy storage device. The method automatically builds at least one model of the energy storage device. The building is based on a design parameter space and employs a machine learning process. The method automatically performs a simulation of the energy storage device using the design parameter space, a design evaluation space, and the at least one model built. The performing produces at least one prediction. The method automatically evolves at least one of (i) the design parameter space and (ii) the design evaluation space. In an event the at least one prediction indicates that a product design objective or model design objective has been achieved, the method automatically converges on the design parameter space evolved, thereby completing a generative design of the energy storage device and, otherwise, repeats the building, performing, and evolving.

Abstract: A computer-implemented method and corresponding computer-based system generate a three-dimensional (3D) multi-scale model of a 3D system. The computer-implemented method generates, at a given scale, an artifact model that indicates properties, characteristics, and artifacts of the 3D system. The computer-implemented method modifies a series of representational models of the 3D system based on the artifact model generated. Modifying the series includes mapping the properties, characteristics, and artifacts to a representational model in the series of representational models at a higher scale or lower scale relative to the given scale. The mapping bridges a given representational model of the series of representational models at the given scale and the representational model at the higher scale or lower scale.

Abstract: The sprinter's training aid is a wearable athletic training apparatus designed to improve a sprinter's technique. The apparatus teaches proper arm-swing action and proper trunk attitude for sprinters. The apparatus is worn over the shoulders and down the back. The apparatus is lightweight and is attached to the body via shoulder straps and adjustable trunk straps. The apparatus provides physical landmarks and visual indicators for proper arm-swing and trunk attitude. The apparatus allows the athlete to move freely and does not encumber the arms, hands, legs or head. The apparatus teaches the athlete to see and feel the correct movement patterns and trunk attitude for maximum sprinting speed.
