Claim 8

A system for handling variable digital information comprising: a key having a leading edge at one end thereof and a longitudinal axis along the length thereof, an active integrated circuit component, a DC battery for powering the component, leads extending between the component and the battery, unplated leads including male contacts extending from the component parallel with the axis, the male contacts having upper contact surfaces located in a plane of contact, the unplated leads being down turned at the leading edge of the key; a container for sealing the component, battery and leads except adjacent to the leading edge of the key; a receptacle having a longitudinal axis along the length thereof parallel with the axis of the key, the receptacle also having plurality of unplated leads with inboard portions couplable to electronic machinery and with outboard portions having lower contact surfaces slidingly, resiliently contactable with the upper contact surfaces of the unplated leads of the key adjacent to the leading edge of the key; and resilient means in the form of a block positioned in contact with the sides of the outboard portions remote from the leads of the key to urge the lower contact surfaces of the receptacle downwardly toward the plane of contact into sliding, resilient contact with the upper contact surfaces of the key whereby, when the key is moved along its axis into sliding contact with the leading portions of the receptacle, high normal forces are generated therebetween to break corrosion existing on the contacting surfaces thereof.

Claim 10

A system for handling variable digital information comprising: a key having a leading edge at one end thereof and a longitudinal axis along the length thereof, an active integrated circuit component, a DC battery for powering the component, leads extending between the component and the battery, unplated leads including male contacts extending from the component parallel with the axis, the male contacts having upper contact surfaces located in a plane of contact, the unplated leads being down turned at the leading edge of the key with one of the unplated leads extending forwardly of others of the unplated leads for the initial grounding of the card; a container for sealing the component, battery and leads except adjacent to the leading edge of the key; a receptacle having a longitudinal axis along the length thereof parallel with the axis of the key, the receptacle also having a plurality of unplated leads with inboard portions couplable to electronic machinery and with outboard portions having lower contact surfaces slidingly, resiliently contactable with the upper contact surfaces of the unplated leads of the key adjacent to the leading edge of the key; and resilient means adjacent to the outboard portions to urge the lower contact surfaces of the receptacle downwardly toward the plane of contact into sliding, resilient contact with the upper contact surfaces of the key whereby, when the key is moved along its axis into sliding contact with the leading portions of the receptacle, high normal forces are generated therebetween to break corrosion existing on the contacting surfaces thereof.
