Abstract: In a first aspect of the present invention, implementing a fast, wide decode in a field programmable gate array by selecting a test probe circuit associated with a column in the array, selecting at least one logic module associated with the test probe circuit, driving the test probe circuit in the at least one logic module by an output of the at least one logic module, and sensing a logic level in the test probe circuit to determine whether a match in the decode at the inputs of the at least one logic module occurred.

Abstract: A field programmable gate array architecture comprises a plurality of horizontal and vertical routing channels each including a plurality of interconnect conductors. Some interconnect conductors are segmented by user-programmable interconnect elements, and some horizontal and vertical interconnect conductors are connectable by user-programmable interconnect elements located at selected intersections between them. An array of rows and columns of logic function modules each having at least one input and one output is superimposed on the routing channels. The inputs and outputs of the logic function modules are connectable to ones of the interconnect conductors in either or both of the horizontal and vertical routing channels. At least one column of random access memory blocks is disposed in the array.

Abstract: An asymmetric microporous membrane with exceptional solvent resistance and highly desirable permeability is disclosed. The membrane is made by a solution-casting or solution-spinning process from a copolyamic acid comprising the condensation reaction product in a solvent of at least three reactants selected from certain diamines and dianhydrides and post-treated to imidize and in some cases cross-link the copolyamic acid. The membrane is useful as an uncoated membrane for ultrafiltration, microfiltration, and membrane contactor applications, or may be used as a support for a permselective coating to form a composite membrane useful in gas separations, reverse osmosis, nanofiltration, pervaporation, or vapor permeation.

Abstract: An enzyme-linked immunoassay for the determination of cyclosporin A levels in whole blood samples is provided based on the utilization of .beta.-D-galactosidase as an enzyme label and chlorophenol red-.beta.-D-galactopyranoside or resorufin-.beta.-D-galactopyranoside as a .beta.-D-galactosidase substrate.

Abstract: The presence and location of amyloid deposits in an organ or body area of a patient is effected by intravenous administration of novel radioactive iodine-labeled amyloid binding compounds and preferably .sup.123 I-labeled compounds to the patient and sensing radiation emitted from the organ or body area.

Abstract: The presence and location of amyloid deposits in an organ or body area of a patient is effected by intravenous administration of novel radioactive iodine-labeled amyloid binding compounds and preferably .sup.123 I-labeled compounds to the patient and sensing radiation emitted from the organ or body area. Novel non-radioactive iodine substituted amyloid binding compounds and amyloid binding compounds which are readily iodinated are further aspects or the invention.

Abstract: A single-chip microprogrammable sequence controller includes a subroutine stack and conditional branching facilities. The controller performs a test and mask operation followed by comparison with a user-defined constant to effect a Boolean sum-of-product function. Address control logic includes a flag signal set by compare logic; the flag is available to a microinstruction decoder where it can be used during a subsequent conditional branch operation based on the setting of the flag.

Abstract: An integrated circuit package having a plurality of pins and a plurality of output structures connected, respectively, to the plurality of pins. Each output structure selectively provides any one of four signals including a registered signal, non-inverted or inverted, or a non-registered signal, non-inverted or inverted, to a pin. Each output structure is configurable or field-programmable by a user or purchaser of the package to provide it with any desired combination of registered and non-registered outputs.

Abstract: An improved circuit for serial scan diagnosis is provided. A state register in the signal path of the digital system under diagnosis is coupled to a diagnostic shift register. Test data is introduced and removed through the diagnostic shift register through a serial input terminal and serial output terminal. For certain operations the serial input terminal becomes a control terminal whereby a minimum number of control lines is required.
