Title: Method and system for data communications using synchronizing signals of different data length
Inventor: ANDO TOSHIHIDE
IPC: G07B15/00
Filed: 1998-01-30
Abstract: A  road  side  communication  equipment  is  provided crossing over lanes of an expressway, so that a communication processing for toll collection is executed between the road side equipment and an on-board equipment passing a communication area.          The  road  side  equipment  sends  signals  using  a  32-bit synchronizing signal for the start slot of each frame and a 16-bit synchronizing signal for subsequent slots of the frame.  The on-board equipment receives this to perform signal receiving processing.  The received communication signals are then digital-demodulated and entered to a shift register  so that the bit pattern  is  compared  in  two  comparators  to  detect  the synchronizing signal.  According to the output from AND circuits, the synchronizing signal is distinguished from the synchronizing signal to determine the received data and receive subsequent data.
Patent CA-2231644-A1 (CA)
Inventor: HOLDAWAY CHARLES R
IPC: H02P8/28
Filed: 1996-09-11
Abstract: A motor control system that reduces noise while reducing power requirements but providing sufficient torque. A one-phase-on drive mode modified to microstep between "one phase on" positions is used to accelerate the motor in a non-linear manner to a maximum speed. The microstep drive modes have a constant period, and the step rate of the motor is increased by decreasing the number of microsteps in succeeding steps of the motor. A modified full step waveform maintains the motor at the maximum speed, where the current to one winding of the step motor changes polarity within one motor step while the other remains approximately constant providing increased smoothness in the drive and reduced noise. The polarity changes in accordance with the inductance and the compliance voltage of the motor. A one-phase-on waveform modified to include microsteps between "one phase on" positions later decelerates the motor in a non-linear manner, and the motor stops in a detent position until another waveform of steps is delivered to the motor.

Title: Cbi analogs of cc-1065 and the duocarmycins
Inventor: BOGER DALE L
IPC: C07D487/04
Filed: 1996-10-03
Abstract: Analogs of the antitumor antibiotics CC-1065 and the duocarmycins incorporate the 1,2,9,9a-tetrahydrocyclopropa[c]benz[e]indol-4-one (CBI) alkylation subunit. The CBI-based analogs have potent cytotoxic activity and are useful as efficacious antitumor compounds. A direct relationship between functional stability and in vitro cytotoxic potency is disclosed. The CBI-based analogs are easily synthesized and are 4x more stable and 4x more potent than the corresponding analogs containing the authentic CPI alkylation subunit of CC-1065 and comparable in potency to agents containing the authentic alkylation subunit of duocarmycin SA. Similarly, the CBI-based agents alkylate DNA with an unaltered sequence selectivity at an enhanced rate and with a greater efficiency than the corresponding CPI analog and were comparable to the corresponding analog incorporating the duocarmycin SA alkylation subunit.  Systematic and extensive modifications and simplifications in the DNA binding subunits attached to CBI are also described.

Title: Modified kaolins
Inventor: MACKINNON IAN DONALD RICHARD
IPC: C01B33/40
Filed: 1996-10-23
Abstract: A process for the preparation of a modified kaolin from a kaolin group mineral which includes expansion and contraction of layers of the kaolin group mineral. The layers comprising one Si-tetrahedral sheet and one Al-octahedral sheet. The expansion and contraction may be initiated by initial intercalation of a reagent which can penetrate kaolin layers to reach an interlayer region therebetween to form an intercalate. Subsequently, the intercalation may be followed by de-intercalation which involves removal of the reagent. By the above process, there is provided crystalline modified kaolins having the following properties: (i) an increased interlayer space compared to corresponding kaolin group minerals; (ii) an increased susceptibility to intercalation by cations, anions or salts compared to corresponding kaolin group minerals; and (iii) an increased exfoliated morphology compared to corresponding kaolin group minerals.

Title: Fault data collection as part of computer unit restart
Inventor: TATTARI LAURI
IPC: G06F/
Filed: 1996-10-29
Abstract: In problem situations of a computer controlling a process, such as transmission of calls, it is very important to direct the maintenance operations in the correct manner at the correct places as rapidly as possible. In the fault data collection method according to the invention, fault data is collected selectively by using empirical data about what type of information is useful in solving problems. Data (P10A  - P40A) about each process family is searched for from the list of process families PL in the data area (DA) of the computer's operating system. By means of the first process (P10) of the process family, data is obtained about the other processes (P11 - P14) of the family. The data structures (PA) of the processes (P10 - P14) provide data about the memory resources reserved by the process, time supervision, etc.. By comparing the content of the data structures (PA) to the empirical base values, data structures (PA) are copied to the storage area (SA) from the processes that are to be examined in greater detail. The data structures are collected after the restart has been activated but before new data has been written into the part of the main memory where these data structures (PA) are stored.

Inventor: HA-DUONG TUAN
IPC: H04Q3/00
Filed: 1998-05-11
Abstract: In order to sort data elements each including a sort key, storage means are organized according to a binary tree of 2"-1 nodes which are each able to contain an element and are distributed in n successive stages numbered from 0 to n-1, stage q containing nodes 2q to 2q+1-1. The elements are dispersed within the tree in such a way that each element contained in a node i has a smaller sort key than those of the elements contained in nodes 2i and 2i+1. The trees managed by m successive controllers (21q) each associated with a stage (20q) or with several consecutive stages of the tree (2~m~n), with n-1 interface registers (26q) between successive stages, among which those located between the controllers are pipeline registers allowing parallel working of the controllers so as to modify the contents of the tree upon exchange or insertion command propagated from stage 0 to stage n-1.

Title: Method and apparatus for multiplexing and distributing data with preformatted real-time video
Inventor: SHEN PAUL
IPC: H04N7/52
Filed: 1996-11-08
Abstract: A system for providing efficient constant bit rate distribution of variable bit-rate encoded video programs while facilitating the distribution of encoded video programs, along with Auxiliary Data of a general character, to one or more receivers. At a particular receiver, a customized augmented video program is created by inserting selected portions of the Auxiliary Data into a selected encoded video program. The encoded video portion of the augmented video program can be transmitted, decoded and displayed in real time, while the Auxiliary Data need not be transmitted in real time but can be stored locally at the receiver for real-time presentation at a later time. Real-time presentation might include insertion into the video program while non-real-time presentation might include insertion into non-video applications separate from the video program.

Filed: 1997-03-25
Abstract: A method of and system for detecting the possible fraudulent use of a telecommunications network involves applying rule-based criteria to generate a plurality of fraud alarms, each corresponding to an individual rule. Each alarm is associated with a particular customer, and for each individual customer a note is made of the total alarms generated by that customer and the grouping of individual alarm types generated.
