Abstract: A removable protective nose cover for a submersible structure having a nose section is disclosed. The removable protective nose cover can include a plurality of shell members, each of the shell members having a forward end and an aft end. Each shell member can also be dimensioned to fit adjacent to and around the nose section of the submersible structure and thereby form a protective shell. A central nose member having a locking member can also be included, the locking member being operable to attach the central nose member to each of the forward ends of the shell members. The aft ends of the shell members can be attached to each other using a plurality of attachment clips such that the attachment of the central nose member to each of the forward ends of the shell members and the attachment of the adjacent aft ends of the shell members form the removable protective nose cover for the submersible structure.

Abstract: Disclosed is a beam strain gauge to measure strain in a material which incorporates the theory of beam mechanics and the use of a full Wheatstone bridge circuit. In all cases the beam or beams used are not attached directly to the material to be measured, thereby making the beam or beams insensitive to transverse strain. The use of beam mechanics allows the use of the full Wheatstone bridge circuit, which has many desirable properties for strain measurement. Some of these properties are self compensation for temperature and a higher gauge output signal. The beam strain gauge can be employed using silicon chip technology and provides many advantages over the current conventional strain gauges.

Abstract: An accelerometer includes a bottom leg, two side legs, a beam, two support strips, a mass, a loading column, and at least one resistor mounted on the beam. The two side legs extend upwardly from the bottom leg, and a lower end of each side leg is connected to the bottom leg. The beam is fixed above the bottom leg and between the side legs, and is connected to each of the side legs. The two support strips extend from the side legs toward each other, and the mass is mounted above the beam and connected to the side legs by the support strips. The loading column connects the mass and the beam, such that an acceleration experienced by the mass causes a bending in said beam.

Abstract: This invention is a fishing fly lure of a flat-bodied nymph hook comprising a fishing hook; a double-bowed center section attached to the fishing hook and a fishing eye attached to the double-bowed center section. The double-bowed center section is wrapped with fly preparation threaded to form a flat center section of the fishing lure.
