摘要： A convertible, integrated handling and testing system is described for interfacing a printed circuit board or card having electronic devices at predetermined locations thereon to a probe plate having electrical contacts at predetermined locations. A method is also described for converting a conventional vacuum test fixture to a mechanical test fixture on tester apparatus, and for converting it back to a vacuum fixture again when desired. The board handling system includes a unique conveyor system which is capable of staging one board while testing another. The conveyor system can be disengaged from one board (for testing) while another board is advanced toward the test fixture.

摘要： A board fixturing system is described for interfacing a printed circuit board having electronic devices at predetermined locations thereon to a probe plate having electrical contacts at predetermined locations. The fixturing system is mechanical and avoids the problems and limitations of the conventional vacuum fixturing systems. The fixturing system includes a unique conveyor system which is capable of staging one board while testing another, i.e. one board can be tested while another board is advanced toward the test fixture. A cassette system for the probe plates is also provided.

摘要： An illumination system for illuminating a scan region on an object and for providing a white level reference for a detector may comprise a light source for producing light rays and an elongate lens having a first end and a second end positioned between the light source and the scan region. The lens collects some of the light rays from the light source and directs them onto the scan region. A first spot lens is positioned adjacent the first end of the elongate lens and a second spot lens is positioned adjacent the second end of the elongate lens. The first and second spot lenses direct some of the light rays from the light source toward first and second ends of the scan line. A white level reference mark is positioned adjacent the lens and the light source so that some of the light rays from the light source are reflected by the white level reference mark to the detector.

摘要： Page sensor apparatus for producing a signal related to a thickness of a sheet of paper may comprise a base plate and a foot plate positioned in opposed relation. The base and foot plates are arranged to allow the paper to pass therebetween, so that the base and foot plates become separated by a distance substantially equal to the thickness of the sheet of paper. Capacitance sensing apparatus connected to the base plate and the foot plate senses changes in the electrical capacitance of the base and foot plates and generates an output signal related thereto, the output signal being related to the plate separation, thus paper thickness.

摘要： A document scanner method and apparatus is provided which allows for the detection of the presence and size of a document to be scanned. The scanner would also determine whether the document being scanned is crooked. The document scanner includes an automatic document feeder, which feeds the document into the scanner. As the document is being fed into the scanner by the automatic document feeder, an array of CCDs detects the size of the document using a code strip. The CCD signal of the detected document size is then converted to an electronic signal which is sent to application software. The application software then instructs the scanner as to the area to be scanned.

摘要： Grounding technology is provided for a short-wire, circuit board test fixture. As a result of the grounding technology, the ground between a circuit board test system and a circuit board under test can be reliably controlled. The grounding technology provides testing at extremely higher speeds by minimizing ground bounce. An internal ground plane is situated in the test fixture. Pursuant to one embodiment of the invention, a coax assembly at ground potential surrounds critical signal paths between the internal ground plane and an alignment plate situated at the bottom of the test fixture. Either a conductive alignment plate or a conductive ground comb affixed to a non-conductive alignment plate is implemented to permit conduction of the ground signal between the board test system and the coax assembly. In another embodiment, an array of ground personality pins provides conduction of the ground signal between the internal ground plane and the board test system. The ground personality pins are clustered around critical signal paths to control impedance.
