Abstract: A system and a method for contactless power generation for a lighting arrangement configured on an aircraft propeller. Power is produced when a magnetic field produced by an arrangement of magnets on an airframe magnetically interacts with coils configured on an aircraft propeller. When the propeller spins, rotation of the mounted coils through the magnetic fields of the magnets generate power. Electrical wiring carrying charge from the coils to the lights is laid into grooves formed in propeller blades which connect to lights inserted in formed sockets.

Abstract: An attachment for conventional weapon mounted lasers that provides a larger and more convenient and ergonomic interface of actuating the laser. The laser attachment is molded or formed as a single piece from a pliable rubber or similar material and has a switch cover and a pair of opposed side straps. The side straps are dimensioned and configured to wrap around the laser and affix to the bottom of the laser. The switch cover is dimensioned and configured to seat and nest over the activation switch on the top of the laser. The switch cover has interior (bottom) and exterior (top) surfaces that substantially mirror the profile to the activation switch; however, the switch cover has a diameter larger than the activation switch. Depressing any area of the switch cover actuates the laser. The larger surface area of the switch cover provides improved acquisition for the user without increasing size or footprint of the laser.
