Abstract
Residual magnetic locks, brakes, rotation inhibitors, clutches, actuators, and latches. The residual magnetic devices can include a core housing and an armature. The residual magnetic devices can include a coil that receives a magnetization current to create an irreversible residual magnetic force between the core housing and the armature.
Claims59
A method of preventing actuation of an ignition switch in a vehicle, the method comprising:
- forming a substantially closed magnetic path between an armature and a core housing in order to create an irreversible residual magnetic force;
- and
- substantially preventing actuation of the ignition switch due to the irreversible residual magnetic force.
An ignition actuation blocking device for use in a vehicle having an ignition assembly, the ignition assembly including an input device and an ignition switch, the ignition actuation blocking device comprising:
- a core housing coupled to one of the vehicle and the ignition switch;
- an armature coupled to one of the vehicle and the ignition switch;
- and
- a coil adjacent to the core housing, the coil receiving a magnetization current to create a substantially closed magnetic path between the armature and the core housing in order to create an irreversible residual magnetic force and to prevent actuation of the ignition switch.
