Abstract: A solenoid system for a vehicle can include an electromagnetic device, permanent magnet, and sensor. The electromagnetic device can include a housing, armature, and solenoid to move the armature axially relative to the housing. When the armature is in an extended position, a first end of the armature can extend further in a first direction relative to the housing than when in a retracted position. The sensor can be fixedly coupled to the housing and can detect a magnetic field of a permanent magnet based on the position of the armature.

Abstract: A spring-driven permanent magnet generator comprising a bobbin-mounted coil, inner and outer frame members defining diametrically opposite pole pieces and a structure which cages or essentially surrounds the bobbin and coil combination. A rotor comprising the integral combination of disc and shaft portions carries a two-pole permanent magnet and is, in the assembled structure, located such that the shaft portion extends through the frame structure and the caged coil to place a permanent magnet between the pole pieces which are defined by the caging frame structure. A flat wound spring drives the shaft portion relative to the frame structure to induce a short duration voltage in the coil which can be used, by way of example, as an electronic fuse in an explosive device such as a hand grenade.

Abstract: A clockspring driven permanent magnet generator comprising a bobbin-mounted coil, inner and outer frame members defining diametrically opposite pole pieces and a structure which cages or essentially surrounds the bobbin and coil combination. A rotor comprising the integral combination of disc and shaft portions carries a two-pole permanent magnet and is, in the assembled structure, located such that the shaft portion extends through the frame structure and the caged coil to place a permanent magnet between the pole pieces which are defined by the caging frame structure.
