Patent CA-2091920-A1 (CA)
Title: Apparatus and method for picture representation by data compression
Inventor: YOMDIN YOSEF
IPC: H04N19/80
Filed: 1993-03-18
Abstract: A method and all apparatus for representing picture by data compression are provided. The method comprises dividing the picture into regions, registering the value of a brightness function, fixing a characteristic scale for each region, dividing the region into cells having a linear dimension in the order of the characteristic scale, identifying basic structures in each cell, representing said structures by models, and storing and/or transmitting data defining the models, which data represent the primary compression of the picture and can be further compressed or otherwise processed. The apparatus comprises means for carrying out the several steps of the method. The basic structures may be chosen from among predetermined lists and such structures are described. In a preferred aspect of the invention they are identified and represented by constructing geometric models representing them, associating to each geometrical model a mathematical model, condensing said geometrical or mathematical models to define a global model for each cell and encoding and quantizing the data defining the global model. Methods are described for constructing the geometric models, based on the distribution of the values of the brightness function by determining a grid, determining an approximating function, at each point of the grid, and comparing the values of the derivatives and gradients of the approximating function with a predetermined set of thresholds. When representing color pictures, the method is applied successively to each of the basic colors or to a luminance signal and two reduced bandwidth colour-information carrying signals obtained by known transformation of colour data.  An image of the original picture can then be produced from the compressed data, and it may be a faithful image or a desired transformation thereof, if the compressed data have been correspondingly transformed.  Various application of the invention are described, comprising the application to video sequences.

IPC: H04M11/06
Filed: 1993-05-12
Abstract: A multimode service system processes calls routed to it by a digital switch in a telecommunications system wherein choices are selectable by the user. Calls are processed by automatically determining the mode of communication utilized by the calling party and communicating with the calling party utilizing the calling party's communication mode to obtain information needed to route the call or implement user selectable features. A reply from the user provides information which determines feature selection or a call routing path. The multimode servicesystem transmits a signal to the telecommunications system which defines the feature or path selection based on the reply from the user.
Patent CA-2099277-A1 (CA)
Inventor: BERLINGER WILLIBALD G
IPC: F02F3/00
Filed: 1991-11-29
Abstract: The design and construction of past piston assemblies having a wrist pin bolted to a connecting rod have excessive weight and structural components, and requires more complex machining techniques and tooling. The present invention overcomes these problems by providing a piston assembly (30) with a wrist pin (36) attached to a piston member (32). Thus, the length of the leg members (80) are short and do not require a portion surrounding the wrist pin (36). The results being reduced piston member (32) and piston assembly (30) weight and lower inertia, a simplified forging or casting process, a more easily machinable cavity (86) within the piston member (32) and a higher quality piston assembly (30).

Title: Humanised antibodies having modified allotypic determinants
Inventor: CLARK MICHAEL R
IPC: C07K16/00
Filed: 1992-03-12
Abstract: The invention relates to molecules which have an amino acid sequence derivable from part or all of the constant region of an immunoglobulin heavy chain. The constant regions are of a particular isotype and have one or more allotypic determinants. The amino acid sequence is substantially homologous to the amino acid sequence of the constant region. However, it has been altered so that it is without at least one of said allotypic determinants by making its sequence the site for an allotypic determinant identical to the amino acid sequence from the corresponding position in another equivalent immunoglobulin constant region of a different isotype. The invention provides synthetic immunoglobulins with reduced allotypic differences as compared to a given wild-type immunoglobulin.

Patent CA-2119335-A1 (CA)
Title: Packet data communication system
Inventor: HEIMAN FREDRIC
IPC: H04L12/56
Filed: 1994-03-17
Abstract: A packet data transmission system is used to link a number of remote hand-he ld data-gathering units such as bar code readers to a central computer which maintains a database management system. Data packets are sent from the remote units by a n RF link to intermediate base stations, then sent by the base stations to the central computer by a serial link. A frequency-hopping transmission method is used for the RF  link. The remote units and base stations are all synchronized to a repeating pseud o- random sequence of frequencies in a band (902-928 MHz) which allows this type of transmis- sion. The remote hand-held units initiate an exchange using RF transmission to and from the base stations, receiving only during a rigid time window following a transmission from the remote unit. The base stations cannot initiate communication to the remote units, but instead send data to the remote units only as part of the exchange. The reply messages from the base stations to the remotes contain synchronizi ng information to maintain coherence with the pseudo-random sequence.

IPC: G03D3/08
Filed: 1994-08-12
Abstract: When a ring with an exposed dental X-ray film mounted thereon is thrown into a first tank filled with a processing solution, the ring is scooped into a space of a ring-holding portion of a rotating arm through a first opening.  As the ring-holding portion is moving in the tank, the ring is pushed by a tilted bottom portion while being held within the space by a release preventing wall and a door so that the ring is also moving together with the ring-holding portion.  When the ring-holding portion has fully moved out of the tank, the door is opened and the ring is released from the space into an adjacent tank through a second opening.           As the door is kept closed until the ring-holding portion fully moves out of the tank, the automated development processor according to this invention is free of the conventional problem that the ring could fall and sink to a bottom of the tank during its movement through the tank.
