    Abstract: An apparatus for locating a workpiece on a processing surface includes a first locator arm assembly, a second locator arm assembly, and a pivotal member. The first locator arm assembly includes a first surface disposed for lateral movement and mating engagement with a first portion of the workpiece. The second locator arm assembly includes a second surface disposed for lateral movement parallel to the first surface, the second surface further for mating engagement with a second, opposite side, portion of the workpiece. Lastly, pivotal member is disposed for pivotal movement about a pivot point and symmetrically coupled, with a zero tolerance buildup, between the first locator arm assembly and the second locator arm assembly for inducing an equal but opposite lateral movement in the first and second mating engagement surfaces of the first and second locator arm assemblies, respectively, whereby the workpiece is accurately located on the processing surface between respective first and second mating engagement surfaces as the surfaces are moved towards one another.

    Abstract: A substrate tester and method of testing are disclosed in which the tester moves a substrate to be tested into a precise location within the tester prior to making contact with fragile tester pins. The substrate is then clamped in a precise X-Y location relative to the tester contact pins, also without making contact with the tester pins. Next the substrate top surface is moved quickly to a precise Z-axis location, whereupon the tester contact pins are finally applied to the substrate using Z-axis motion only. In addition, a mechanism is included that features a cam-pivot arm micro-switch combination to sense when a product is not properly positioned in or missing from the test station.

    Abstract: An apparatus for locating a workpiece on a processing surface includes a first locator arm assembly, a second locator arm assembly, and a pivotal member. The first locator arm assembly includes a first multiple position locator jaw disposed for lateral movement and mating engagement with a first portion of the workpiece. The second locator arm assembly includes a second multiple position locator jaw disposed for lateral movement parallel to the first multiple position locator jaw and further for mating engagement with a second, opposite side, portion of the workpiece. Lastly, the pivotal member is disposed for pivotal movement about a pivot point. The pivotal member is symmetrically coupled between the first locator arm assembly and the second locator arm assembly for inducing an equal but opposite lateral movement in the first and second locator jaws to accurately locate the workpiece on the processing surface between the first and second locator jaws as the locator jaws move towards one another.

    Abstract: Methods of creating libraries of biological polymers are provided. The construction of a library employs a probability matrix for a reference sequence, and a constraint vector for which is applied to the probability matrix to produce a substitution scheme. The substitution scheme is then used to generate a library comprising substitutions recommended by the substitution scheme. The library members, or host cells comprising and/or expressing them, can be screened for desired changes in a property of interest in the biological polymers in the library.
