The ACCELERATION DISTORTION RESISTANT RING LASER GYRO (RLG) (10) shown here includes a control mirror (12) subject to distortion beyond the path length control capabilities of the RLG (10) when subjected to intense translational acceleration in the direction (20) perpendicular to the face of the control mirror (12). An anti-parallel compensating mirror (14) is provided to offset the path length change. Additional design flexibility may be obtained by replacing the compensating mirror (14) with a compensating group of mirrors.

Acceleration distortion resistant ring laser gyro

An alignment and path length control apparatus having a mirror housing having a base and a closed wall. The base has a mirrored external surface. The closed wall has a central axis. The closed wall is joined to the base at a base end of the closed wall by a flexible web. The closed wall extends above the base and terminates at a rim defining an aperture. The base has a central region coupled to the cylindrical wall. A post extends from the central region of the base within the cylindrical wall to a top end. A mirror axis extends from the mirrored external surface through the post. The central axis is substantially parallel to the mirror axis. An alignment transducer responds to a first alignment control signal by applying at least a first force between the post and the wall to deflect the mirror axis with respect to the central axis. A linear transducer responds to a linear displacement control signal by applying an axial force to the post to displace the central region longitudinally along the central axis.

Interferometer alignment control apparatus

A bowling apparatus is provided for use by an operator in a wheelchair to triggerably launch a ball, the ball rolling in a preselected direction on a navigable surface such as a bowling alley. The bowling apparatus is further adapted to control the terminal velocity and spin of the ball at release. The bowling apparatus comprises:
