A scanning assembly is disclosed for providing controlled movement of a mirror. The scanning assembly includes a motor shaft of a limited rotation motor, a scanning device, and a scanning device mounting unit. The mirror mounting unit includes a tapered base for coupling the scanning device mounting unit to the output shaft of the limited rotation motor. One of the tapered base and the output shaft includes a cylindrical tapered male plug having a decreasing inner diameter that decreases along a direction of coupling of the tapered base and the output shaft for engaging the tapered base to the output shaft. The tapered base includes an overall taper angle of at most about 4. 0 degrees from the rotational axis of the output shaft.

A test fixture for facilitating connection between a pin grid array, such as those found on multi-lead electronic components, and the test leads of a diagnostic device, useful for testing such components after they are mounted on printed circuit boards. A base element is formed of transparent plastic material and carries an array of connectors, the number and arrangement of which depend upon the component to be tested. Each connector includes a test lead connector, adapted for attachment to a test lead, and a pin engagement member, adapted for making and retaining physical contact with a component pin. The pin engagement member is carried resiliently in the connector body, able to move longitudinally therein. A resilient seal means extends around the outer periphery of the underside of the base member, defining a well in the space below the base member. The seal means may include multiple resilient seal layers, separated by stiffeners.
