Abstract: Differential signaling between integrated circuit chips uses fewer than 2 external wires per bit transmitted. Rather than pairing wires into groups of two, the external wires are part of a larger group of 2i+2 wires. Half of the wires in the group are driven low while the other half of the wires are driven high. Since the wires are not paired, adjacent wires can have the same logical state. Differential comparators in the receiver chip compare each wire with all other wires in the group. All outputs of comparators that have a wire as one of its two inputs are input to a majority logic block that evaluates the logical state of the wire. Since half of the wires are in one state, the majority of the remaining wires are in the opposite state of the wire being evaluated. Thus the majority of the comparator outputs indicate the opposite state of the wire being evaluated.

Abstract: A high strength, high clamp blind bolt for fastening structural workpieces, which blind bolt has a core pin with a blind side head and a plurality of locking grooves or threads, a high stand-off collar adapted to be swaged into the locking grooves or a nut adapted to be threaded onto the pin threads, a compression frangible main sleeve structure and an expandable, short fixed length blind side sleeve structure; the blind bolt is set by a relative axial force applied to the pin which forces the short blind sleeve structure against the main sleeve structure causing the blind side sleeve to expand and form a blind side structural load bearing blind head; the relative axial force can be applied by pulling in a swage configuration or by torque in a threaded configuration; the core pin head acts on the main sleeve structure to cause a frangible portion to shear and reduce the main sleeve structure length after which the blind head engages the blind side of the workpieces; the high stand-off collar is then swaged in

Abstract: A swage type fastener including a pin and a collar adapted to be swaged onto the pin by the application of a relative axial force by an installaiton tool, with the pin having a lockgroove portion, a tubular collar having an inner and outer end and adapted to be located on the pin and having a collar shank portion adapted to be swaged into the lock groove portion by the relative axial force applied between the pin and the outer end of the collar by the installation tool, the collar having a through bore which has a reduced diameter bore portion whereby the collar is generally piloted on the pin, and the collar shank portion being generally frusto conically shaped from the reduced diameter bore portion to an enlarged bore portion at the outer end, the collar shank portion having a generally uniform wall thickness from the outer end for a distance over its swageable length whereby the frusto conical shape of the collar shank portion provides a high hold-off to resist initiation of swage of the outer end of the c
