Title: Enhanced pressure measurement flow control system
Inventor: KAMEN DEAN L
IPC: A61M39/26
Filed: 1988-09-06
Granted: 1991-10-08
Abstract: Abstract of the Disclosure The present invention provides a system for measuring flow of a fluid through a line.   In the system, a region of fluid along the line is isolated from pressure effects outside of the region.   A source region contains a measurement gas in communication with the isolated region, such that the source means and the isolated region together define a fixed volume, and such that a change in volume of fluid in the isolated region produces a complementary change in the volume of the source means with a resulting change in the pressure of the measurement gas contained in the source region.   Further provided is a reservoir in communication with the source means for containing a known volume of measurement gas, and means for pumping measurement gas from the reservoir.   The pressure of the measurement gas in the reservoir and the source region is monitored.   This pressure data is then analyzed to determine the volume of fluid in the isolated region

Title: Computer interface system
Inventor: MCKINNEY KENELM L
IPC: G06F3/00
Filed: 1988-09-14
Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE         A data transfer interface unit for use with a computer having a parallel data port to transfer data between the computer and one or more peripheral units.  The interface unit generates handshaking signals when the start of communication with a peripheral unit is initiated and temporarily stores blocks of data to be transferred between the computer and the peripheral unit.  The interface generates an interface clock signal which is synchronous with the computer's clock signal and begins the transfer of the data after a predetermined time delay from the time at which the start has been initiated, the time delay being an integral multiple of the interface clock period and the data transfer being completed in a time which is less than the time period required to generate an error difference between the computer clock and the interface clock.

Abstract: ABSTRACT     A testing circuit interfaces serially with the data path of an embedded memory circuit formed from at least one memory unit having separated data input and output lines and tandem addressing.  Part of the testing circuit is a series of two-input multiplexer units which are adapted to be embedded on the same chip as the memory circuit.  The outputs of the multiplexer units connect to a respective one of the data input lines of the memory circuit.  Excepting the first bit position, a first input of each multiplexer unit is adapted to connect to the data output line of the adjacent bit position in the memory circuit.  The second inputs of the multiplexer units are adapted to connect to the data bus of the chip.  A further part of the testing circuit is a finite state machine which is adapted to connect to the first input of the multiplexer unit at the first bit position and to the data output line at the last bit position.  During testing, the finite state machine actuates the multiplexer units to connect the first inputs, and for each address outputs a series of test bits, shifts those bits through the addressed word by a series of read and write operations, and examines those bits after their passage through the addressed word for defects in the memory circuit at that address.  The finite state machine may or may not be embedded on the same chip as the memory circuit.
