31. These instruments may also have a relay contact for use by external control circuits , to indicate synchronism. 32. Reed relays can switch faster than larger relays and require very little power from the control circuit . 33. They consist of only four elements, combined in different ways : cylinders, ball-and-socket joints, motors, and control circuits . 34. For high voltages under very low In-Out difference there will be significant power loss in the control circuit . 35. The low voltage power supply provides 74 V DC power for the doors, communications, toilet, and control circuits . 36. The external control circuits remove power when the wipers reach the desired position; that could be the home position. 37. The serial nature of the G-15's memory was carried over into the design of its arithmetic and control circuits . 38. The design of the control circuits allows for an Collins-built A . P . 103 autopilot to be incorporated. 39. Aspiring BEAM roboticists often have problems with the lack of direct control over " pure " BEAM control circuits . 40. In the 1950s, the diode-matrix control circuits were not widespread due to their significant dimensions and high power consumption.
