An automotive engine has a turbocharger, a wastegate valve for controlling flow rate of exhaust gas applied to a turbine of the turbocharger, and an actuator for controlling the wastegate valve. A standard supercharging pressure is determined dependent on characteristics of the wastegate valve, and a desired supercharging pressure is set in accordance with engine operating conditions. A difference...

A new and improved polymeric membrane for use in biological assays is provided. A blotting assay employing 1,2-dioxetanes as a source of chemiluminescent employs, as an improved membrane, a polymer comprised of at least one monomer of the formula: The membranes reduce background signal, improve sensitivity and reliability.

Oriented polyester film primer coated with a hydrolyzed aminosilane IS disclosed. The aminosilanes in the unhydrolyzed state have the formula: (R<1>)aSi(R<2>)b(R<3>)c wherein R<1> is a functional group with at least one primary amino group; R<2> is a hydrolyzeable group such as a lower alkoxy group, an acetoxy group, or a halide; and R<3> is a nonreactive, nonhydrolyzeable group such as a lower a...

The invention is a modular and hierarchically organized set of computer programs which comprise methods for controlling a system of semi-autonomous automatically guided vehicles, such as mobile robots. The methods include control programs which: execute in stationary control computers; communicate between the stationary control computer programs and corresponding programs which execute in mobile c...
