摘要: A method for verification of components installed on a printed circuit board includes the step of capturing an image of an entire printed circuit board and components mounted thereon using a scanning device. After it has been determined that a printed circuit board having no defects, the scanned image of the circuit board has no defects is stored in a memory. The image of the entire printed circuit board under test, and having potential defects is then captured using a scanning device. The image of the printed circuit board under test is then stored in a memory. The stored image of the printed circuit board having no defects is then overlaid in registration with the stored image of the printed circuit board with potential defects on a display in alternating sequence in order to visually provide an indication of a defective component or defective component placement on the printed circuit board under test to an operator.

摘要: A method for repairing a printed circuit board includes the step of generating fault data relating to the plots or layout of a printed circuit board from a circuit board testing device. The printed circuit board under test is positioned on a workstation. An image containing repair data based on the fault data is projected directly onto the printed circuit board and is overlaid in registration with the plot or layout of the printed circuit board to assist in operator repair.

摘要: A system for reducing the number of points to be tested on a printed circuit board where the printed circuit board includes a plurality of network traces each having end points and a plurality of pads provides for the identification of the end points of each network trace of the plurality of network traces. Certain ones of the plurality of network traces network located within a predetermined distance of one another are grouped to form a plurality of groups of network traces. The identified end points of the grouped network traces are connected together within each group of network traces to form a continuous trace having one pair of end points for each group of network traces. The end points are used for testing the printed circuit board.

摘要: A system for reducing the number of points to be tested on a dual sided printed circuit board. The circuit board includes a top and a bottom surface and a plurality of network traces extending across both sides of the printed circuit board. Each network trace includes end points. The system provides for identifying the end points of a network trace extending on both sides of the printed circuit board. The mid-point along the network trace which is common to both sides of the printed circuit board is identified. Structure is provided for independently testing each side of the printed circuit board between one end point and the mid-point on the top surface of the printed circuit board and between the mid-point and the second end point on the bottom surface of the printed circuit board.

摘要: A blending device is described for providing a uniform mix of particulate material. A pressurized fluid is conducted into a plenum surrounding a mixing chamber proximate the lower end thereof. An annular slit in the wall between the plenum and the mixing chamber allows the pressurized fluid to discharge through the slit for agitating particulate material contained in the mixing chamber.

摘要: A substance analyzer utilizing Prompt Gamma Neutron Activation Analysis for identifying characteristics of a substance and method of manufacturing the same are disclosed. The analyzer is small enough to be portable and to allow its use in many applications where current analyzers cannot be utilized. The analyzer uses a neutron radiation source and a gamma-ray detector to activate the sample material and detect the prompt gamma rays emitted by the sample material. A novel housing for such an analyzer and method for making the housing are also described. Novel methods of operating such an analyzer including via a communications network are also disclosed. Also disclosed are data analysis methods that improve the accuracy and sensitivity of the results of such material analysis.

摘要: Methods and compositions are provided for producing sterile drug formulations, where drugs are thermolabile and pH sensitive. The method provides formulating the drug with a physiologically acceptable inorganic or organic acidic buffer for buffering at a pH in excess of 6, reducing the pH below about 5 by adding carbon dioxide, and heat sterilizing the formulation in a gas permeable sealed container. The resulting formulation is substantially free of degraded drug and at the desired physiologically acceptable pH. Also, formulations are provided which do not cause clotting during administration.
