Patent CA-1310425-C (CA)
Title: License management methods and systems
Inventor: BARBER JON H
IPC: G06F21/12
Filed: 1988-10-14
Granted: 1992-11-17
Abstract: ABSTRACT OF THE DISCLOSURE    License management systems and methods allow licenses for a computer program to be available for use at each of a plurality of nodes of a network.  If a valid license file at a local node contains an unexpired, available license, a license manager at the local node permits the computer program to be executed at the requesting local node.  If no such license is available in a valid license file at such local node, the license manager searches the other nodes for a valid license file containing an unexpired, available license.   In one embodiment, if an unexpired available license is located in a valid license file at a second for "remote") node, the license manager transfers such license to the local node, and assigns and encrypts a unique identification to such transferred license.   The original record of the transferred license is modified by erasing it from the license file at the remote node so that the transferred license is no longer available there. In a second embodiment, the license manager modifies the license file to indicate use of the license at the local node without such transfer.   The number of copies of the computer program that are authorized for execution simultaneously on the network is thus limited to the number of licenses that have been loaded into the license files on the network.

Title: High speed parallel multiplier circuit
Inventor: ADILETTA MATTHEW J
IPC: G06F7/52
Filed: 1988-11-23
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE The binary multiplier circuit for obtaining a product of a M-bit multiplier and a N-bit multiplicand includes a multiplier circuit which produces a matrix of original summand bits having M rows and M+N columns and a matrix reduction circuit,  In the ma-trix reduction circuit, for every column of the matrix having three or more original summand bits, groups of three bits are input into full adder circuits which output a sum bit for that column and a carry bit for the column in the next most signifi-cant bit position.  For every column having three or fewer oriqi-nal summand bits, and having the least significant column posi-tion that is not yet reduced to two or fewer bits, groups of two bits are input into a half adder circuit which outputs a sum bit for that column and carry bit for a column in the next most sig-nificant bit position.  Iterative reductions are performed for each column by using full adder circuits for every group of three bits in a column and by using a half adder circuit for any re-maining group of two bits in a column.  The reduction continues until each column of the matrix is reduced to two or fewer bits. The remaining two rows of bits can be input to a carry-propaga-ting adder circuit to output a sum equal to the product.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of measuring linewidth loss during the formation of microelectronic circuitry, including the formation of a test pattern constituted by a series of spaced bars on a photographic mask which is to be used to form a predetermined pattern on a substrate material. Either of the bars or the gaps between the bars have the same predetermined width.  In the former case the gaps, and in the latter case the bars, have widths which differ incremently stepwise from one to the next.  The series of bars are such that the ratio of the widths of one adjacent bar/gap pair is unity.      The resultant pattern which is formed on the substrate as a complement of the test pattern is then inspected, and the position where the bar/gap width ratio of the resultant pattern is unity is noted.  The linewidth can then be calculated loss from a knowledge of the size of the incremental step and the position of the bar/gap width ration unity point on the resultant pattern.

Abstract: A transfer device permits different moving sequences of holding devices for the sheet metal parts which are to be moved through the metal-forming machine.  The holding devices are fastened to carriages.  The carriages are cam-guided, in which case a fist carriage carries out a transfer movement from a working stage to an idle stage while taking along a sheet metal part.  The return movement is interrupted in an intermediate position during the deforming operation of the sheet metal parts.  A second Carriage carries out a transfer movement from the idle stage to a working stage and a return movement which is temporarily interrupted in an intermediate stage.  The vertically extending motional parts of curves are used for the picking-up and depositing of sheet metal parts in working stages; the extended lowering movement is used for the depositing of the holding devices on sliding tables which can be moved into the press. As a result of the low-mass construction by means of carriages, high accelerations are possible in the movements.  The transfer movements are shortened significantly by the use of intermediate depositing devices in the idle stages.
