Patent CA-2065803-A1 (CA)
Inventor: MURAKAMI TOKUMICHI
IPC: H04N19/503
Filed: 1992-04-10
Abstract: A motion compensation predicting coding apparatus includes a motion detector for comparing pixel data in an image signal with pixel data of the previous image signal to generate a motion vector. The motion vector is indicative of the displacement differences between the image signal and the previous image signal. The image signal may be organized into blocks of pixel data for a single field or for multiple fields when motion detection is performed on the image signal by the motion detector. A subtracter generates a prediction compensation error signal by subtracting the pixel data in the previous image signal from the pixel data of the image signal. A coder receives the prediction compensation error signal and generates an appropriate coded output. The apparatus may also include an adaptive blocking mechanism for receiving the prediction compensation error signal and organizing the data in the signal into blocks into one of several fashions as dictated by the motion vector.

Title: Personal computer with anticipatory memory control signalling
Inventor: FUOCO DANIEL P
IPC: G06F13/18
Filed: 1992-04-29
Abstract: This  invention  relates  to  personal  computers,  and  more particularly to personal computers in which arbitration for control over a data handling bus occurs among a plurality of "master"  devices coupled directly to the bus  and memory address signals are varied in response to such arbitration. The  personal  computer  system  has  a  high  speed  local processor   data bus,   an   input/output   data   bus,   a microprocessor coupled directly to the local processor bus, volatile memory  coupled  to  the  local  processor bus for volatile storage of data,  and a bus interface controller coupled directly to the local processor bus and directly to the  input/output  data  bus  for  providing  communications between the buses.   The bus interface controller provides for  arbitration  among  devices  directly  coupled  to  the input/output data bus for access to the input/output data bus and to the local processor bus,  and for arbitration among the input/output data bus and said microprocessor for access  to  the  local  processor  bus.   The  bus  interface controller  is  also  coupled  to  the  volatile  memory  for supplying row address select signals to the volatile memory and thereby selecting data storage areas to be accessed, and responds to a change in access granted to the local bus by changing the row address select signal supplied to the volatile memory in preparation for access to potentially different data storage areas of the volatile memory.

Title: Anticorrosive agent of steam and condenser systems and anticorrosive method of steam and condenser systems
Inventor: AKAMA SHUNICHI
IPC: C23F11/02
Filed: 1991-03-28
Abstract: ABSTRACT    The present invention relates to a method of preventing the occurrence of corrosion in pipes and devices of steam and condenser systems.    In case that steam generated in boilers is to be used for food processing and the production process of pharmaceutical agents, and for humidification of air conditioning of buildings, a high degree of hygienic safety is required for steam.  However, there have not been any anticorrosive chemical agents with the certification such that the agents can be used safely with no concerns about the objective of the use of steam and about the concentration of the agents in steam.  When the use of hygienic steam is desirable, there have been frequently the cases in which anticorrosive chemical agents are not used even if there are concerns about the corrosion of pipes and devices of steam and condenser systems.    The present invention is thus to provide an anticorrosive method of steam and condenser systems, comprising adding the anticorrosive agent containing as the effective component thereof at least one compound selected from the group consisting of vitamin A and vitamin E, whereby hygienically safe steam can be used for food processing and the like, with no concerns about the occurrence of steam contamination and corrosion of pipes due to chemical agents and the like.

Title: Multi-port microwave coupler
Inventor: TONDRYK WIESLAW J
IPC: H01P5/16
Filed: 1992-07-14
Abstract: A multi-port microwave coupler has six input ports In 1, In 2, In 3, In 4, In 5 and In 6 and six output ports Out 1, Out 2, Out 3, Out 4, Out 5 and Out 6 and is synthesised from nine 2 x 2 90° hybrid couplers which are arranged as three sets, that is a first set A, B and C, a second set D, E and F and a third set G, H and I. A first group of transmission lines 11, 12, 13, 14, 15 and 16 interconnect the first and second sets of hybrid couplers, and a second group of transmission lines 21, 22, 23, 24, 25 and 26 interconnect the second and third sets of hybrid couplers.     The first and third sets of couplers each give a 3dB power reduction, but the second set give a 1:2 power split between their outputs. Three 90° phase shift devices X, Y and Z correct the phase of the signals in the transmission lines 21, 25 and 24 respectively. When equal amplitude signals are applied to all of the input ports, the combined signal can be directed to any one of the output ports by appropriately selecting the respective phases of the input signals. The first and second groups of transmission lines can be arranged as respective transmission rings so that all cross-overs in the transmission lines are avoided thereby providing a planar realisation of a 6 x 6 multi-port microwave coupler. The invention is of application to higher order n x n multi-port microwave couplers where n = 2p x 2q with both p and q as whole numbers.

Title: Powered diving board
Inventor: SEPT GORDON
IPC: A63B5/10
Filed: 1992-08-07
Abstract: ABSTRACT OF THE DISCLOSURE A power assisted diving board with the object of maximizing vertical upward thrust and comprised of an electrically controlled pneumatic actuator affixed to the underside of a hinged platform which incorporates at one end a foot activated electrical switch. A microswitch is incorporated in a platform support structure such that as the hinged platform reaches the limits of its travel the microswitch is activated. The signals from the foot switch and the microswitch form a binary equivalent number which is presented to an Electronic Control Unit (ECU) for processing. The ECU, depending upon the binary number present at the switch inputs, produces an appropriate output signal to a solenoid which, in turn, operates a 4-way fluid valve controlling the flow of fluid to either the upper or lower chambers of a double acting actuator.

Title: Poker and other gaming chip cleaning and sanitizing device
Inventor: KEATE PETER B L
IPC: B08B11/02
Filed: 1993-02-22
Abstract: B) ABSTRACT Existing methods used to clean gaming chips include washing by hand and using a standard dish or clothes washing machine. The disadvantages of these methods are the time taken when washed by hand, the time and damage caused when washing by the dish or clothes washing machine and the delays caused by having to take the chips out of the trays and resort them into similar currency denominations after cleaning. Existing machines do not bath the chips in ultraviolet light to destroy bacteria, analysis has shown that chips handled constantly in gambling casinos are heavily contaminated with bacteria that can result in infections being passed from one person to another without the persons actually having to have made contact with each other. The containers, (Figs. 1,2,3,4,5 & 6. item 1) which hold the trays of poker style and other gambling chips of various values and denominations and dollar coins during the cleaning process are designed in a manner to be able to enclose trays of various sizes complete with chips. The tray containers are further designed in a manner which allows the chips to move whilst in the trays and the CONTAINER in the upright, sideways and inverted position and be fully exposed to the cleaning process (Figs. 2 & 6, item 1), this exposure and movement allows the chips to drift apart to ensure that the cleaning process can access the inside and all around the chips whilst they are being cleaned, sanitized and dried. The tray counting mechanism (Fig. 1, item 2), ensures that an exact count can be maintained of the trays and chips being cleaned at all times.
