A system determines a centerline of a vehicle to adjust a forward aim of a camera or ranging unit. The vehicle has a forward axle transverse to the centerline, a first and second wheels at distal ends of the forward axle, a rearward axle transverse to the centerline, and a third and fourth wheels at distal ends of the rearward axle. The system includes a jig for engagement under the vehicle, a light source attached to the jig for projecting light forward of the jig along the centerline of the vehicle when the jig is fully engaged, and a target placed on the centerline of the vehicle so as to be illuminated by the light source at a fixed distance from the vehicle.

The present invention is directed to an apparatus for testing a plurality of on/off solenoid valves and a plurality of proportional solenoid valves of an automotive transmission. The apparatus includes an on/off valve switch for each of the on/off solenoid valves and a series of preset current switches for each of the proportional solenoid valves. An on/off solenoid circuit is electrically connected to the on/off valve switches and includes a plurality of outputs for connection to the on/off solenoid valves. In response to actuation of the on/off valve switches, the on/off solenoid circuit is operable to generate electrical actuation signals for transmission through the outputs to the on/off solenoid valves, respectively. Proportional solenoid circuits are electrically connected to the series of the preset current switches, respectively. Each proportional solenoid circuit has an output for connection to one of the proportional solenoid valves. Each proportional solenoid circuit is operable in response to selective actuation of the associated series of preset current switches to generate and transmit electrical preset current signals to one of the proportional solenoid valves through the output, wherein said preset current signals have different preset current levels.

An apparatus for measuring tension of piston rings includes a cylindrical support fixture having a circumferential groove formed therearound for receiving and holding a piston ring. A rigid base supports a plurality of components of the apparatus. A strong, thin band, formed from a material sufficiently strong to withstand repeated applications of pulling force thereto, is mounted to the base, and is held between two clamps. The band has a loop formed therein, for receiving the support fixture with a piston ring mounted therein. The apparatus also includes reciprocally movable structure for tightening the band around the support fixture, such as a slidably movable clamp assembly at one end of the band. The apparatus further includes mechanism for measuring tension on the band, and fluid activatable mechanism for vertically reciprocating a portion of the support fixture. In a preferred embodiment, the reciprocating mechanism is pneumatically activatable, such as by compressed air.
