Abstract: A fishing sinker is comprised of a polyhedron body having a rectangular base and triangular sides with a common blunt vertex, adapted to generate a net upward lifting force during forward motion. The streamlined shape of the sinker also makes it more aerodynamic during casting and minimizes splashing during entry into water. A central channel is formed in the body for receiving an eyelet pin with a swaged end, a straight section extending through said central channel and an integrally formed eyelet portion protruding from the blunt vertex. A plurality of symmetrically arranged stabilizer fins extending along angles of intersection of each adjacent triangular side. The eyelet portion is a resilient eyelet with a slip-on opening biased into a closed position. The vertex makes the sinker quite aerodynamic, as it leads the way on casts through the air and into the water.

Abstract: A scalable cable management system comprises an electronics module with a microcontroller; a plurality of drive modules and a releasably engaged cable cartridge for each drive module. Each cable cartridge houses a lead wire cable spool with an electrical slip ring connected to the wire. Stationary electrical contacts pickup signals from the slip ring for use by the electronics module. A device such as an electric or spring-driven motor, with a gear train and an optional clutch, controllably rotate the cable spool. A cleaning assembly cleans portions of the lead wire as it is extended or retracted. The microcontroller receives strain signals representative of tension on a lead wire from cable strain gauge. The electronics module may also include a defibrillator protection sub-system, a crossbar transfer switch, an instrumentation amplifier and a communications unit. Test terminals are also provided for assessing integrity of each lead wire.
