Patent CA-1282195-C (CA)
Title: Apparatus and method for flexible data base access
Inventor: MASSEY JAMES H
IPC: G06F17/30
Filed: 1988-01-22
Granted: 1991-03-26
Abstract: ABSTRACT            In order to access a data base system, a system user establishes communication with an interface unit associated with the data base system by means of telephone apparatus.  Upon being connected with the data base system, the user is presented with a predetermined verbal message produced by a digitizing speech unit responding to preestablished logic signal sequences.  In response to this message, the user can select from a plurality of verbally presented options by an appropriate activity, such as depressing the appropriate key on the dialing apparatus of a touch-tone telephone apparatus.  By providing a verbal response from the interface unit that is determined by the user response to presented options, the system user can communicate with the interface unit, the verbal responses from the interface unit representing an abbreviated menu for the system user.  As a result of this communi-cation, a system user can interrogate and retrieve data from a data base without data processing apparatus.  The retrieved data can be provided to the system user by a speech synthesizing pro-cedure or can be transmitted to the system user by another procedure determined by the interaction between the data base system and the system user.  This type of interaction between the system and the system user can permit unsophisticated persons to access data bases without operator assistance and without the requirement of availability of data processing apparatus.  When data processing apparatus is available, the user can access the system data bases by menu-driven interaction with interface unit in a conventional manner.

Title: Material layer volume determination with correction band
Inventor: RODRIGUEZ RODOLFO R
IPC: G01N9/12
Filed: 1988-06-30
Granted: 1992-12-22
Abstract: ABSTRACT OF THE DISCLOSURE           A centrifuge tube is used to hold a mixture of several constituents, and also contains a generally cylindrical float.    The float settles,   after cen-trifugation, into the zone occupied by the constituent whose volume is to be measured.  The constituent layer will settle,  after centrifugation,  into the annular space between  the tube bore and the outside of the float  and  will  be  expanded  axially  due  to  the restricted volume of the annular space.  The degree of expansion is dependent upon  the respective sizes of the float O.D.  and the tube bore ID,  both of which must be closely controlled for accurate results.   A known volume of a control material is placed in the tube  to  settle  into  the  annular  space  during centrifugation  in  an  area  thereof  outside  of  the constituent layer zone.  The length of the band of the control material is measured after centrifugation and is compared to a known length which will result if the annular space  is of  the proper  target volume.    A correction factor is thus obtained and applied to all of the other constituent layers which were measured. The band thus forms a varying reference which reflects the actual volume of the annulus.

Title: Thermal compensation mechanism for magnetic disk drive data storage units
Inventor: CAIN MICHAEL A
IPC: G11B5/55
Filed: 1988-11-21
Granted: 1993-01-05
Abstract: ABSTRACT OF THE DISCLOSURE    A magnetic disk memory data storage device has a unitary arm assembly mounted for rotation by an actuator for carrying the transducers and  shifting them across the disk surfaces.         The assembly is subjected to varying temperature during normal operation of the device which causes differential rotation of the individual arms and consequent misalignment of them.  In a design of interest, the arm nearest the deck is most affected.  At least some of this misalignment can be compensated for by placing a slot in the edge of at least one arm and placing a body with a different thermal coefficient into the slot with an interference fit.  If the body has a smaller thermal coefficient than the arm assembly's, the slot should be on the edge opposite the direction in which the misalignment occurs.

Title: Preprocessing implied specifiers in a pipelined processor
Inventor: FITE DAVID B
IPC: G06F9/318
Filed: 1989-08-01
Granted: 1993-11-02
Abstract: PREPROCESSING IMPLIED SPECIFIERS    IN A PIPELINED PROCESSOR                        ABSTRACT    An instruction decoder generates implied specifiers for certain predefined instructions, and an operand processing unit preprocess most of the implied specifiers in the same fashion as express operand specifiers.  For instructions having an implied autoincrement or autodecrement of the stack pointer, an implied read or write access type is assigned to the instruction and the decode logic is configured accordingly.  When an opcode is decoded and is found to have an implied write specifier, a destination operand is created for autodecrementing the stack pointer.  If an opcode is decoded and found to have an implied read specifier, a source operand is created for autoincrementing the stack pointer.  A register or short literal specifier can be decoded simultaneously with the generation of the implied operand.  Therefore some common instructions such as "PUSH Rx" can be decoded in a single cycle.  The preprocessing of implied specifiers in addition permits more complex instructions such as "BSR DEST" to be executed in a single cycle.  Conflicts created by the implied specifiers are handled in the same manner as conflicts for express specifiers.  Moreover, by using the same data paths for both the implied specifiers and the express specifiers, and by inserting queues between the instruction unit and the execution unit, performance gains are realized for instructions having implied specifiers as well as just express specifiers.
