Abstract: An improved method and apparatus for electrically coupling the bond pads of an integrated circuit to a tester. One embodiment the invention includes a probe card having a plurality of test probes and a means for placing the test probes in intimate contact with a corresponding set of bond pads located along the surface of an integrated circuit. Electrical contact is achieved between the test probes and bond pads by inducing a small and rapid cyclic movement between the test probes and bond pads such that the test probes pierce a dielectric layer on the surface of the bond pads. In one embodiment, the cyclic movement between the test probes and bond pads is achieved by the use of a piezoelectric actuator.

Abstract: A method and apparatus for electrically coupling the bond pads of an integrated circuit to a tester using a probe card having a biasing element supporting a plurality of tests probes. In one embodiment, the method includes the steps of placing the test probes in contact with the bond pads and providing a vibrational movement to the biasing element such that the test probes move relative to the bond pads and such that the test probes remove an electrically non-conductive material on the surface of the bond pads to establish an electrical connection between the test probes and the bond pads.

Abstract: A rectilinear drive assembly for a bicycle. The drive assembly includes a pair of tracks that each have a pair of opposing side portions joined by a pair of opposing radial end portions which together define a rectilinear path. The drive assembly also has a pair of pedals that are coupled to the track by a pair of wheel assemblies. The wheel assemblies follow the outline of the tracks so that the pedals move in a rectilinear path. The linear movement of the pedal provides a more efficient transfer of power from the rider's legs to the drive assembly. Each wheel assembly has a pair of inner wheels that roll along an inner surface of the track and a pair of outer wheels that roll along an outer surface of the track. The outer wheels are separated by a distance greater than the separation of the inner wheels to compensate for the different radiuses of the inner and outer surfaces at the radial end portions of the track. The wheel assemblies are connected to chains which rotate a number of sprockets.
