Abstract: In a preferred embodiment, an optical inspection machine for fasteners, including: an inspection station; a main dial rotatable through the inspection station and carrying thereon a plurality of fasteners; a reflective surface surrounding each of the plurality of fasteners to permit inspection light to reflect from the reflective surface and permit viewing of an entire outer circumference of a head of each of the plurality of fasteners to detect head cracks and bursts; and a lower surface of each of the plurality of fasteners being raised above the reflective surface. A method of optically inspecting fasteners is also provided.

Abstract: In a preferred embodiment, a method of training a child for reporting an emergency on a telephone system of the type having an emergency access code, the method including: providing controllable memory apparatus in which at least one training scenario is recorded; providing a first telephone coupled to the controllable memory apparatus; providing a controller coupled to the controllable memory apparatus to cue selected portions of the recorded training scenario to transmit the same to the earpiece of the first telephone; having a child dial the emergency access code on the first telephone; and cuing successive selected portions of the recorded training scenario to elicit answers from the child, over the first telephone, to questions asked in the selected portions, such answers being of the type required by an emergency dispatcher to at least ascertain the location of the emergency.

Abstract: Apparatus and method are disclosed for inspecting a row of hollow pin receptacles in a housing to determine whether or not pins have been properly mounted in the receptacles. A collimated inspection light beam is directed toward one surface of the housing as it passes through an inspection position, so that the inspection beam successively impinges on the receptacles. A photodetector is disposed to face the opposing surface of the housing to receive light, if any, which has passed through the receptacles. Means responsive to the photodetector are provided for generating an output signal indicative of whether or not the pin has been properly mounted in the receptacle. The output signal generating means preferably comprises a threshold detector for detecting when the output of the photodetector exceeds a predetermined threshold.
