Abstract: An apparatus is described for burn-in and/or functional testing of microelectronic circuits of unsingulated wafers. A large number of power, ground, and signal connections can be made to a large number of contacts on a wafer. The apparatus has a cartridge that allows for fanning-in of electric paths. A distribution board has a plurality of interfaces that are strategically positioned to provide a dense configuration. The interfaces are connected through flexible attachments to an array of first connector modules. Each one of the first connector modules can be independently connected to a respective one of a plurality of second connector modules, thereby reducing stresses on a frame of the apparatus. Further features include for example a piston that allows for tight control of forces exerted by terminals onto contacts of a wafer.

Abstract: A commodity trading system having a centralized computer and data base. Each commodity, such as a bale of cotton, or a block of bales, is represented in the data base as a file having all the information unique to such bale, including a title flag. The title flag field of bale record and block record indicates whether the title to the cotton bale, or block of bales, is carried by way of a card-type warehouse receipt, or electronically. The electronic representation of title eliminates the transferral of documentary type title which is traditionally mailed to various locations to follow the trading transactions.
