摘要： A method and apparatus for testing complex processor-based computer modules and their associated computer systems by allowing the normal initialization path between a memory component storing code utilized during initialization and the processor to be interrupted and test code from an external test system to be substituted for initialization code. Following initialization, a two-way communication link between the processor and the test system is created to allow interactive testing and status reporting. The testing method and apparatus maximizes the likelihood of precisely identifying defects on the module under test.

摘要： A device for measuring the level of a bed of finely divided solid such as a catalyst or the like. It can make the level measurement both near the center and near the periphery of the bed from a relatively small opening in the top of a container for the bed. It employs an angled tube with a line extending through the tube. The line has a weight attached to the free end of it. There is a spool mounted on a cross bar at one end of the tube for winding the line and so as to adjust the vertical position of the weight relative to the outer end of the tube.
