Patent CA-2080630-A1 (CA)
Inventor: AMINI NADER
IPC: G06F13/28
Filed: 1992-10-15
Abstract: A computer system is provided comprising system memory and a memory controller for controlling access to system memory, a central processing unit electrically connected with the memory controller, and a bus interface unit electrically connected to the memory controller by a system bus and electrically connected to a plurality of input/output devices by an input/output bus. The bus interface unit is able to sense when said one of said input/output devices has completed a read or write operation over said input/output bus, and includes a buffer circuit wherein read and write data transferred between the system bus and the input/output bus via the bus interface unit is temporarily stored during the transfer. Arbitration control logic resides in said bus interface unit and interacts with a central arbitration controller which resides on the system bus. The central arbitration controller responds to the arbitration control logic to simultaneously perform (i) arbitration cycles wherein the central arbitration controller arbitrates between the plurality of input/output devices and the central processing unit to determine which of the input/output devices or the central processing unit should be granted control of the input/output bus and (ii) grant cycles wherein the central arbitration controller grants control of the input/output bus and extends control of the system bus to one of the input/output devices or the central processing unit.

Title: Liquid composition analyzer and method
Inventor: PAULONIS MICHAEL A
IPC: G01N1/00
Filed: 1991-04-29
Abstract: ABSTRACT OF THE DISCLOSURE         An   apparatus    (30)    which   determines concentrations of each of three components that are intermixed  in  a  homogeneous  solution  (34).    Each component is detectable by at least one characteristic and more than one characteristic is associated with more than one component.   First, characteristics that are quantitatively   detectable   in   relation   to   the concentrations of the components are identified.   A mathematical relationship is then developed between the components and the detectable characteristics using the detectable characteristics as independent variables.  A sample of  the solution is then analyzed to obtain quantitative data of each of the characteristics.  The obtained quantitative data is then employed in the mathematical relationship to obtain the concentration of each of the components.

Patent CA-2083035-A1 (CA)
Inventor: HAVENS DALE I
IPC: F16D55/30
Filed: 1992-11-16
Abstract: The present invention is a brake lever arrangement for a small transmission. The brake mechanism is actuated by the rotational movement of the brake lever which causes friction pucks to move into the brake disc. A spring coupled to the brake lever biases the brake lever in a non-braking position and aligns the brake lever with its plane of rotation to prevent dragging of the friction pucks on the brake disc. Also, a bracket may be provided which has an elongated slot for receiving the upper portion of the brake lever. The bracket aligns the brake lever and guides the movement of the brake lever along one direction.

Title: Dispersion compensating devices and systems
Inventor: ANTOS ANTHONY J
IPC: G02B6/036
Filed: 1992-12-01
Abstract: Disclosed is a family of dispersion compensating optical fibers that are adapted for use with conventional single-mode transmission fibers that are optimized for zero dispersion operation at a wavelength in the range from 1290 nm to 1330 nm to form a transmission link suitable for low dispersion operation in the 1520-1565 nm wavelength window.      The dispersion compensating fibers are capable of providing a dispersion more negative than -20 ps/nm-km and attenuation less than 1 dB/km at wavelengths in the 1520-1565 nm region.      Certain of the dispersion compensating fibers also exhibit a dispersion versus wavelength relationship having a negative slope in the 1520-1565 nm region, to compensate for the dispersion versus wavelength slope of the trandsmission fiber. The dispersion compensating fiber can be advantageously combined with a fiber amplifier to form a compensator that is adapted to overcome attenuation introduced into the system by the dispersion compensating fiber. In one embodiment, the dispersion compensating fiber is also a distributed fiber amplifier.

Title: Real-time dot generator for multiple-channel, slanted, matrix printhead
Inventor: ENTER RUDOLF
IPC: G06K15/10
Filed: 1993-06-07
Abstract: Within a document printing system, a dot generator for determining dot ON/OFF states for a multiple channel matrix print head includes a RAM memory in which is stored print characters received from the print system. The received print characters are stored in ASCII format in predetermined character box memory locations within the RAM memory. The dot generator further includes a ROM memory having (1) a first storage area containing an association table correlating each one of the dot print addresses or locations within the document print zone with one of the character box memory locations within the RAM memory; (2) a second storage area containing an association table correlating each one of the dot print locations with a character box print location row and column number; and (3) a third storage area containing dot state ON/OFF values corresponding to each row of each standard ASCII character. A ROM lookup procedure is utilized to determine the ON/OFF state for each dot location within the print zone. In brief, the dot generator performs the followings steps: (1) The dot generator receives a dot address from the print system and utilizes this address to fetch the character box memory locations (BOX#) for that dot from the first storage area within the ROM. (2) The dot generator fetches the ASCII character from RAM for the BOX# provided by step 1. (3) Simultaneously with step 2, the dot generator fetches the ELEMENT#, a number describing a dot's relative position within a character box, from the second storage area within the ROM, (4) The dot generator then extracts the dot's printing state,i.e. ON or OFF, from the third storage are within the ROM using the ASCII character provided by step 2 and the ELEMENT# from step 3. (5) This process repeats until all channels in the printhead have been determined.
