A vacuum-operated vehicle glass handling system includes a plurality of suction cups movably disposed on a frame. A powered vacuum source is fluidly connected to the plurality of suction cups for providing a vacuum at each of the plurality of suction cups. A powered vacuum source includes a pair of vacuum pumps both fluidly connected to the plurality of suction cups for redundantly providing the vacuum to the plurality of suction cups. A power source is selectively electrically connected to the powered vacuum source. A pair of vacuum actuators is on the frame for selectively electrically connecting the power source to the powered vacuum source so the powered vacuum source can provide the vacuum at the plurality of suction cups. The power source is electrically connected to the powered vacuum source upon actuation of one or both of the pair of vacuum actuators. A pair of release actuators is on the frame for selectively releasing the vacuum provided at the plurality of suction cups. The vacuum is released only upon actuation of both of the pair of released actuators.

Vacuum-operated vehicle glass handling system

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.
