Abstract: A method of automatically mounting a sheet from a cutting table onto a spacer frame of an insulating glass unit begins with identifying a position and orientation of a specified sheet on the cutting table and moving a robotic sheet pickup apparatus to a corresponding position to that identified for the sheet. An edge of the specified sheet is lifted off of the table, beginning with mechanical suction that brings a corner of the sheet to within proximity of a primary vacuum suction of the pickup apparatus. In particular, the pickup apparatus may have a substantially planar platen with a set of channels coupled to a vacuum source. Once the sheet is fully picked up by vacuum suction, the sheet is laid upon a top surface of a tilt table, which can be simply the platen inverted. The table (or platen) is tilted to bring a corner of the sheet to abut against physical fences. Once the position and orientation of the sheet is so known, the sheet is oriented to correspond to a frame, and attached thereto.

Abstract: An LED-based color measurement instrument including an illumination system and a sensing system. The illumination system includes modulated LEDs and a temperature control system for regulating the temperature of the LEDs, thereby improving the consistency of their performance. The sensing system includes a photodiode, a transimpedance amplifier, and an integrator in the first stage to cancel the effect of ambient light on the output of the first stage. The sensing system also includes a lens system for imaging a target area of the target sample onto the photo sensor in a manner so that the product of the target area times the solid angle captured by the lens system is generally uniform over a selected range of distances, thereby reducing the positional sensitivity of the instrument with respect to the target sample.

Abstract: A color measurement system includes a hand held color measurement instrument, which may be provided with a wireless interface to a computer. The color measurement system includes a scanning guide for holding the hand held color measurement instrument in proper alignment with a color target. The scanning guide includes a calibration reference to allow convenient calibration of the hand-held color measurement instrument. The hand-held color instrument includes an illumination ring to provide visual feedback to the user. The color of the illumination ring changes in order to display a color similar to that being read by the hand-held color measurement instrument. Color management profiling of the hand held color measurement instrument illumination ring improves the color rendition capability of the illumination ring.
