Patent ID: 8708112

Claim:
An inertial braking system controller comprising an elongated casing member defining an axis along its elongated length, and having an opening at one end of said elongated length; a movable plate housed within said casing and including at least one opening adapted to allow light to pass therethrough; a piston member including a pad member at a distal end thereof and placed inside of said one end of said casing member with said pad member facing outwards from the interior of said casing member and adapted to move along said axis, and is rigidly connected at an opposite end to an adjacent end of said movable plate; an electronic circuit board rigidly connected within said casing and including at least one opto-coupler positioned such that said at least one opening in said movable plate is aligned with a light beam produced by said at least one opto-coupler and allows said light beam to pass therethrough, and a biasing member positioned between said movable plate and a portion of the interior wall of said casing member, such that when said braking system controller is in a static state said light beam passes through said at least one opening, and when said piston member is pushed inwardly said movable plate moves with it, thereby moving said at least one opening along said axis and thereby blocking said light beam resulting in an electronic signal being produced by said electronic circuit board to be sent to said at least one coil member, which thereby produces power adapted to be sent to braking members of trailer member.
