  • Publication number: 20240103068
    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.

  • Patent number: 9181505
    Abstract: The instant invention pertains to new processes which produce an energy source effectively, efficiently, and in a more environmentally friendly manner. The process comprises hydrolyzing a lignocellulosic feedstock to form lignocellulosic hydrolyzate and a hydrolyzate residue. The lignocellulosic hydrolyzate is treated to produce hydrogen. The hydrolyzate residue may be reacted with hydrogen in the presence of a catalyst to yield the energy source.

  • Patent number: 7384621
    Abstract: Methods for converting hydrocarbon fuels to hydrogen-rich reformate that incorporate a carbon dioxide fixing mechanism into the initial hydrocarbon conversion process. The mechanism utilizes a carbon dioxide fixing material to remove carbon dioxide from the reformate product stream. The removal of carbon dioxide from the product stream shifts the reforming reaction equilibrium toward higher hydrocarbon conversion with only small amounts of carbon oxides produced. Repeated absorption/desorption of carbon dioxide by the fixing materials tends to decrease the fixing capacity of the materials. Hydration of the carbon dioxide fixing materials between one or more cycles serves to sustain their fixing capacity and to enhance the efficiencies of the reforming and shift reactions occurring in the catalyst bed. Hydration can occur during reactor start-up or shut down, periodically over a number of cycles, and/or upon a monitored change in the reformate composition.
