IPC: H04L12/56
Filed: 1990-09-04
Abstract: A data flow fed to the transmission medium is composed of data cells which are each transmitted via one of said transmission channels and which each comprise a control word group containing one or more control words, and also an information word group containing one or more information words, which control words are read out in the monitoring device; at least one variable being maintained, in addition, in the monitoring device which, on arrival of a data cell, is mutated in accordance with a mutation algorithm containing one or more mutation parameters, and said mutated variable then being processed in accordance with an assessment algorithm containing one or more assessment parameters to form an assessment signal. The method according to the invention is characterized in that, on arrival of a data cell, a number of variables can be mutated and processed in the monitoring device to a corresponding number of assessment signals as mentioned, and furthermore, in that, for each data cell, the control word group mentioned comprises a control word which, on arrival of a data cell, is read out in the monitoring device and which gives an indication of those variables which have to be mutated and then processed and of the mutation and assessment algorithms to be used in doing so. Furthermore, it is characteristic of the invention that one or more of the assessment signals mentioned are processed in accordance with a combination algorithm containing one or more combination parameters to form a control signal, and furthermore that, for each data cell, the control word group mentioned comprises a control word, which on arrival of a data cell is read out in the monitoring device and which gives an indication of the assessment signals which have to be processed and of the combination algorithm to be used in doing so. A device for implementing the method according to the invention preferably comprises a reading unit (1) to which the data cells are presented for reading out at least the control words of said data cells, a setting device (2) for setting, on the basis of the data read out in the reading unit, which variables, or algorithms or parameters have to be used for generating the control signal (c), furthermore a number of mutation units (4a,b,c,..) for mutating the respective variables indicated by the setting unit, and also a number of assessment units (5a,b,c,..) for processing the respective mutated variables to form the respective assessment signals (b), one or more combination units (6) for combining the assessment signals concerned to form one or more control signals (c), and a switching unit (7) for temporarily storing the contents of the data cell and transmitting or not transmitting the data cell depending on the control signal concerned.

Patent CA-2029429-A1 (CA)
IPC: G05D19/02
Filed: 1990-11-07
Abstract: ABSTRACT OF THE DISCLOSURE The electric energy generated by an electric gener-ator driven by an engine on a motor vehicle is stored in a large-capacity capacitor when the rotational speed of the engine increases while the engine is idling, thereby impos-ing a load on the engine.  At this time, the increase in the rotational speed of the engine is suppressed.  The electric energy stored in the capacitor is supplied to a battery on the motor vehicle, charging the battery.

Title: Plaque removing toothbrush
Inventor: CURTIS JOHN P
IPC: A46B9/04
Filed: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE     A toothbrush comprising a head having a  flat  surface  facing upwardly, the head joined to a handle.  The tufts of bristles are arranged in two groups of rows, each row extending transversely of the head.  The rows of the first and second groups alternate with each other along the longitudinal axis of the head.  In the first group, the two laterally outermost tufts of each row tilt sidewise towards their respective nearest side of the head, this tilt being about 12 degrees. The middle tuft of each of the second group extends substantially vertically upwardly from the head.   The laterally  outermost tufts of the second group tilt laterally inwardly toward each other by about 8 degrees.  The tufts define three functional groups of tufts.  The tuft arrangement is such that the  cleaning action  is  substantially independent of any particular brushing technique employed by the user.

Abstract: In a speech recognition system for deciding an input pattern as  one  of  reference  patterns  by  calculating dissimilarities of the input pattern and the reference patterns and selecting a particular one of the dissimilarities which is lower  than  a  threshold value,  in order  to  reduce  noise accompanying an input speech pattern in the input pattern, an average noise level is detected from an input pattern before the input speech pattern is detected and a noise factor is produced  corresponding  to  the  average  noise  level.  The dissimilarities are multiplied by the noise factor to produce products.  The products are compared with the threshold value to recognize the input speech pattern.  In a system using the known clockwise DP matching with the beam search technique, the beam width factor is determined as a function of the noise level.

Title: Self centering elevator cable safety brake
Inventor: BURRELL MICHAEL P
IPC: B66B5/16
Filed: 1992-03-27
Abstract: BP File No. 6225-001 ABSTRACT OF DISCLOSURE                      An elevator cable safety brake is disclosed. The brake includes a first housing which is slidably mounted in a second housing. The first housing has an opening through which the elevator cables can pass. On one side of the elevator cables is located a first brake pad which is carried by the first housing. On the other side of the opening is located a second brake pad which is generally wedge shaped. The second brake pad is carried on a sled which is slidably housed within the first housing. The second brake pad may be moved between a free running position and a braking position. The wedge shaped second brake pad may be selectively released under certain trip conditions from the free running position to the braking position. Such conditions include the unintended overspeed operation  of  the  elevator,  a  power  failure,  or  the elevator commencing movement before the elevator doors are fully closed. A governor trips a trip lever effecting the release of the second wedge shaped brake pad. The slidable interaction between the sled and the first housing and the second  housing  enables  the  brake  device  to  be  self centering around the cables during the braking action. In an alternate embodiment the safety brake works in both the up and down directions.
