Abstract: A pressure transducer suitable for use as a component of a passive occupant detection system installed in a passenger vehicle. The transducer comprises first and second contact members separated by a spacing member. The first contact member has on a surface thereof a primary contact comprising first and second terminations and portions spaced apart in a first direction. The second contact member has on a surface thereof a plurality of secondary contacts crossing and facing the spaced-apart portions of the primary contact through an opening in the spacing member. Application of an increasing force causes the contact members to move toward each other, causing an increasing number of the spaced-apart portions to be shorted out by the secondary contacts and causing an increasing number of secondary contacts to contact the primary contact, thereby altering the electrical path between the terminations of the primary contact.

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.

Abstract: A connector for making multiple pressed co-axial connections is comprised of an electrically conductive block which has a top surface, a bottom surface, a plurality of signal holes which extend from the top surface to the bottom surface, and a ground terminal. Top and bottom electrically insulative plates are respectively attached to the top and bottom surfaces of the block. Each plate has alignment holes that are aligned with the signal holes; lying in each signal hole is the body of a respective signal contact; and each signal contact has two springy probes which extend from the body thru respective alignment holes in the top and bottom plates. These springy probes are for contacting external signal pads, and they hold the body of each signal contact such that it is surrounded by a uniform air gap in the center of its respective signal hole.
