Abstract (en)

[origin: WO0157346A1] A cam assembly (140) may be constructed with cylinder plug (116) perforated by a centrally positioned keyway (118), and having an exposed circumferential surface surrounding the keyway (118) rotatably fitted within a centrally positioned keyhole of a housing (126), and rotated within the centrally positioned keyhole in response to rotational force applied by a key (500) conformingly corresponding to the cylinder plug (116) through an arc. A cam (102) mounted either coaxially with the cylinder plug (116), or radially offset from the cylinder plug (116), is positioned within the housing (126) to rotate with the cylinder plug (116) as the key (500) conformingly corresponding to the lock (116) manually applies a rotational force to the cylinder plug (116) and rotates through the arc, while a member (110) attached to the cam (102) and eccentrically positioned relative to the keyway (118), drives the bolt (112) between extended and retracted positions as the cylinder plug (116) rotates through the arc. An electronic circuit (130) containing a memory (534, 536) and a microprocessor (530), is mounted upon and supported by the cam (102) to rotate with the cam (102) through the arc. The electronic circuit (130) operationally responds to digital data carried by the key (500) that is in electronic conformance to data stored within the memory (514, 516), by electrically energizing a release mechanism that is spaced-apart from the axis of rotation of the cylinder plug (116), to move between a deployed position preventing rotation of the cam (102) relative to the housing (126), and a released position accommodating the rotation of the cam (102) relative to the housing (126).
