Patent CA-2141171-A1 (CA)
Title: System and method for resource assignment and scheduling
Inventor: SISLEY ELIZABETH M
IPC: G06Q10/10
Filed: 1995-01-26
Abstract: A system and method for assigning and scheduling resource requests to resource providers use a modified "best-first" search technique that combines optimization, artificial intelligence, and constraint-processing to arrive at near-optimal assignment and scheduling solutions.  In response to changes in a dynamic resource environment, potential changes to an existing assignment set are evaluated in a search for a better solution.  New calls are assigned and scheduled as they are received, and the assignment set is readjusted as the field service environment changes, resulting in global optimization.  Each search operation is in response to either an incremental change to the assignment set such as adding a new resource request, removing a pending resource request, reassigning a pending resource request, or to a request for further evaluation.  Thus, the search technique assumes that the existing assignment set is already optimized, and limits the task only to evaluating the effects of the incremental change.  In addition, each search operation produces a complete assignment and scheduling solution.  Consequently, the search can be terminated to accept the best solution generated so far, making the technique an "anytime" search.

Patent CA-2145316-A1 (CA)
Title: Prioritization of microprocessors in multiprocessor computer systems
Inventor: TIPLEY ROGER E
IPC: G06F13/36
Filed: 1993-09-24
Abstract: Three prioritization schemes for determining which of several CPUs receives priority to become bus master of a host bus in a multiprocessor system, and an arbitration scheme for transferring control from one bus master to another.  Each prioritization scheme prioritizes n elements, where a total of (n/2)x(n-1) priority bits monitors the relative priority between each pair of elements.  An element receives the highest priority when each of the n-1 priority bits associated with that element points to it.  In the arbitration scheme, the current bus master of the host bus determines when transfer of control of the host bus occurs as governed by one of the prioritization schemes.  The arbitration scheme gives EISA bus masters, RAM refresh and DMA greater priority than CPUs acting as bus masters, and allows a temporary bus master to interrupt the current bus master to perform a write-back cache intervention cycle.  The arbitration scheme also supports address pipelining, bursting, split transactions and reservations of CPUs aborted when attempting a locked cycle.  Address pipelining allows the next bus master to assert its address and status signals before the beginning of the data transfer phase of the next bus master.  Split transactions allows a CPU posting a read to the EISA bus to arbitrate the host bus to another device without re-arbitrating for the host bus to retrieve the data. The data is asserted on the host bus when it is idle even if the host bus is being controlled by another device.

Title: Bucket Elevator Conveyors
Inventor: CHORLTON DEREK CARR
IPC: B65G17/16
Filed: 1993-10-15
Abstract: A bucket elevator conveyor comprises a frame housing (1) incorporated a track to route a pair of parallel chains (2) carrying buckets (3) pivotally mounted (11a, 30) therebetween through an endless circuit including loading (14) and discharge (20) stations. The chains consist of links (12) connected together by pins (11) pivoting in elongated holes (25) such that the chains are shorter in compression than when under tension, the ends of adjacent links (12) including interengaging portions (40, 41) to cause the chains to adopt a relatively stiff state when in compression. The chains (2) are maintained under compression in a section of track at the loading station (14) by two pairs of sprockets (6, 8) positioned at the entry and exit ends of the section and spaced apart to maintain the chains under compression, the sprockets (6) at the entry end being driven by an electric motor drive (15). The spacing of the buckets (3) is such that when the chains (2) are in compression at the loading station (14) the end edge portions of adjacent buckets (3) are in contact, and when the chain is under tension at the discharge station (20) the buckets (3) can be rotated through 360° without colliding.
Patent CA-2149350-A1 (CA)
Title: Master-slave data communication system
Inventor: OSADA TOMIO
IPC: H04Q11/04
Filed: 1995-05-15
Abstract: Upward/downward data arranged in a time-division multiplexed frame, including a common subchannel for priority transmission and private subchannels for transmission request/enable signals, are exchanged via an upward/downward data signal line between a plurality of slave stations and a master station having a priority circuit and an internal communication device.  A slave station establishes the transmission request signal and transmits it to the priority circuit through the upward data signal line.  The priority circuit selects one transmission request signal to assign priority for transmission to a corresponding slave station and then establishes the transmission enable signal and transmits it through the downward data signal line based on the selected signal.  When the signal is acknowledged, the corresponding slave station establishes a message signal and transmits to the master station through the upward data signal line.

IPC: H04L27/14
Filed: 1995-05-31
Abstract: A signal modulated by frequency-shift keying is input to a detector consisting of an instantaneous phase detection circuit that detects the instantaneous phase of the input signal, a differentiating circuit that differentiates the instantaneous phase to obtain the instantaneous frequency, and a baseband processing circuit that recovers clock and data signals from the instantaneous frequency.  To detect the instantaneous phase, the instantaneous phase detection circuit compares the logic levels of the input signal and a clock signal, and filters the resulting bit stream with a digital low-pass filter.  The detector consists entirely of digital circuits that are well suited for large-scale integration.

Patent CA-2173302-A1 (CA)
Inventor: GANDHI MALAN BHATKI
IPC: G10L17/00
Filed: 1996-04-02
Abstract: A new speaker verification method, termed Mixture Decomposition Discrimination, (MDD) and a new apparatus for using MDD are presented. MDD takes mixture component score information from a speaker independent recognizer and transmits this information while it is still decomposed as a mixture of component scores that indicate the response of the states of the HMM before this information is combined into a single speaker independent recognizer parameter. MDD can be veryeffective in improving the performance of existing verification methods based onspeaker dependent HMMs with cohort normalization because the errors of the two speaker verification methods are very uncorrelated statistically. Experimental results have shown that when MDD is incorporated into a system that also uses speaker dependent HMMs, the resulting hybrid system has its average equal error rate reduced by 46% compared to cohort normalized speaker independent HMM. MDD is used with a speaker dependent linear discriminator which has relatively low computational and storage requirements. Thus, the increased performance of a hybrid MDD/CNHMM system may be achieved with minimal increase in computational and data storage assets.
