Abstract: A power system includes an output voltage terminal that is coupled by a first conductor to one pressed power contact which is then coupled by a second conductor to an electronic device. Also, the electronic device is coupled by a third conductor to one pressed signal contact which is then coupled by a fourth conductor to an output voltage feedback terminal on the power supply. Further, the power system includes a fault detection circuit which is coupled to the fourth conductor. In operation, the fault detection circuit senses if the pressed signal contact is open at a time when the pressed signal contact is supposed to be closed. If an open contact is sensed, the fault detection circuit sends a signal to an operator which indicates that corrective action is needed.

Abstract: A connector for sending power to an IC-chip thru two pressed joints in series; includes a solid block having a top surface, a bottom surface, and a side with a slot that extends from the top surface to the bottom surface; and 2) a springy strip of metal having a center section which is held by the slot in the block. The springy strip also has a first end section which extends from the center section and includes a springy input contact that is cantilevered above the top surface of the block. The springy strip further has a second end section which extends from the center section and includes a springy output contact that is cantilevered below the bottom surface of the block.

Abstract: A connector for sending power to an IC-chip thru four pressed joints in series includes a solid conductive block having a top surface with a first pair of spaced-apart channels and a bottom surface with a second pair of spaced apart channels. The connector also includes a first springy contact having a center section which touches the top surface of the block in the space between the first pair of channels, and having two ends which are held by the first pair of channels. The connector further includes a second springy contact having a center section which touches the bottom surface of the block in the space between the second pair of channels, and having two ends which are held by the second pair of channels.
