Non-contact electro-magnetic actuator and method

A Non-Contact Electro-Magnetic Actuator configured for use in a firearm assembly configured to work with user-actuable systems with sensors, comprising:

• a receiver assembly attached to and responsive to a trigger assembly is configured with a stock or chassis having a middle section that defines a lumen or cavity having a trigger motion sensing sidewall segment which is configured proximate said trigger assembly, wherein said stock or chassis is configured to receive, support and operate with the user-actuable systems with sensors;
• wherein said trigger motion sensing sidewall segment includes a trigger motion sensor which does not physically contact or attach to said trigger assembly and is instead spaced from every component of said trigger assembly by a selected trigger-to-sensor distance when said receiver carrying said trigger assembly is installed in said stock or chassis;
• wherein said trigger assembly comprises a trigger assembly housing which supports a safety mechanism actuable by a safety lever;
• said trigger assembly being configured to provide movement in response to a force applied by a user;
• wherein said trigger assembly housing comprises first and second spaced wall plates, and further comprises a trigger bracket pivotally mounted between said first and second spaced wall plates and configured to pivot within the housing about a pivot point positioned within the housing and a trigger shoe carried by said trigger bracket which is configured to disengage a firing mechanism in response to said force applied by said user;
• said trigger assembly being configured to provide a first stage movement in response to a first force applied by a user and, if the user applies a second force greater than said first force, a second stage movement.

• and wherein said trigger assembly comprises a trigger assembly housing which supports a safety mechanism actuable by a safety lever;
• said trigger assembly being configured to provide movement in response to a force applied by a user;
• wherein said wherein said trigger assembly defines a transverse trigger motion sensing axis;
• wherein said transverse trigger motion sensing axis is aligned to intersect said trigger motion sensor which is proximate to but not part of or in contact with said trigger assembly;
• wherein said trigger motion sensor is configured to sense, without contacting or interfering with the trigger assembly in any way, at least one of (a) said first stage movement or (b) actuation of said safety lever, and generate a “trigger motion sensed” signal in response thereto.
