Abstract: A computer-implemented method includes receiving design and/or engineering data (D/E data) corresponding to a prototype representation of a product and transmitting one or more inputs derived from the D/E data to one or more digital engineering tools for processing. The method also includes receiving engineering-related data outputs from the one or more digital engineering tools and receiving data corresponding to one or more common validation and verification (V&V products). The method further includes identifying one or more requirements for the product based on the data corresponding to the one or more common V&V products; determining whether or not the one or more requirements have been satisfied; and presenting information corresponding to the engineering-related data outputs and/or the data corresponding to the one or more common V&V products. The method also includes receiving instructions from the user device, and performing one or more manipulations of the D/E data.

Abstract: An outdoorsman's support or chair is comprised of a substantially filled flexible container provided with shoulder straps for easy transport. The flexible container is filled with pellets and is preferably waterproof. It is adaptable to conform to the shape of a person providing comfortable support and insulation from the environment. The flexible container may be provided with a plurality of other straps which may be utilized for attaching other objects or gear to it during transport and for mounting the chair to various other structures, such as the trunk and limbs of trees. The chair is comprised of a spherical structure at one end and an elongated portion at a second end. The elongated portion at the second end may be folded over and juxtaposed to the spherical structure and secured by a folding strap for ease in transport.
