Inventor: MACFARLANE TREVOR
IPC: F16L41/06
Filed: 1996-12-31
Abstract: A hot tap connection comprising: (i) a main supply pipe, (ii) a side branch pipeconnected to the main supply pipe, (iii) a reinforcing saddle surrounding the main supply pipe and the side branch pipe, (iv) a first gap between the main supply pipe and the reinforcing saddle, (v) a second gap between the side branch pipe and the reinforcing saddle, and (vi) a solid material substantially filling the first gap and the second gap. The method for producing the hot tap connection is also described. The method comprises the steps of: (i) connecting a side branch pipe to a desired location on a main supply pipe; (ii) surrounding the side branch pipe and the main supply pipe with a reinforcing saddle; (iii) defining a first gap between the main supply pipe and the reinforcing saddle, and a second gap between the side branch pipe and the reinforcing saddle; (iv) injecting a pumpable material into the first gap and the second gap; (v) curing the pumpable material to produce a solid material; (vi) cutting a coupon of the main supply pipe within the side branch pipe to produce an opening in the main supply pipe to allow gas to flow therethrough; (vii) removing the coupon from the side branch pipe. The hot tap connection is advantageous as, in most installations, it can be used as a permanent connection between a main supply pipe and a side branch pipe.
Patent CA-2195547-A1 (CA)
Inventor: LANIADO SHLOMO
IPC: A61B5/024
Filed: 1995-02-14
Abstract: L'invention se rapporte à un procédé de contrôle de consommation de nourriture d'un sujet et qui indique si l'ingestion de nourriture dépasse une quantité autorisée prédéterminée. Ce procédé consiste à contrôler le patient sur une durée prédéterminée afin d'établir une relation empirique concernant ce sujet entre une modification d'au moins une variable physiologique et une cadence d'ingestion et/ou quantité de nourriture ingérée. Au début de chaque repas, la modification de chacune des variables physiologiques appropriées est mesurée de façon à déterminer, à partir de la relation empirique, une cadence d'ingestion et/ou quantité estimée de nourriture ingérée. Ceci permet de calculer, pour un sujet, un temps maximum d'ingestion de la quantité de nourriture autorisée et prédéterminée, et, lorsque ce temps est écoulé, un signal est donné pour qu'il s'arrête de manger. Un système comprend une montre-bracelet (20) dotée d'un transducteur ultrasonore Doppler (13) qui se place sur l'artère radiale de l'utilisateur et déclenche une alarme audible lorsque le patient a mangé sur une durée suffisante pour consommer la quantité autorisée et prédéterminée de nourriture. La montre peut également comporter, le cas échéant, une fonction d'autoprogrammation pour pouvoir déterminer la relation empirique concernant le sujet.

IPC: H04N21/47
Filed: 1997-11-12
Abstract: A system and method  for displaying MPEG-2  packets  as  a hierarchy of tables within a window of a graphical display.  This hierarchial display is updated continuously as new packets are received, thus providing a real time display.  When a packet is received, and the location of that packet has not been identified, the packet  is  placed at  the  top of  the  hierarchy.   Once a subsequent  packet  is  received  wherein  the  subsequent  packet identifies the location of the earlier received packet, the earlier received packet  is  moved  to  its  correct  location within the hierarchy.   When a user of the system clicks one of the tables within the hierarchy,  the system saves the next data packet or packets containing data for the table into a display table buffer.        The system then displays a second window and formats the data from the display table buffer into the second window.

Title: Processing a video signal so as to modify an image represented thereby
Inventor: MACHIN DAVID JOHN
IPC: G06T13/80
Filed: 1996-07-23
Abstract: To overcome the problem in a video telephony system that a caller looking at his display will not at the same time be looking at a video camera positioned beside the display, the video signal produced by the camera is processed so that the caller's eyes appear to be indeed looking at the camera. Parts of the video signal which represent the eye or eyes of the caller are located and modified so as to move the pupils and irises in the represented image. These parts of the signal are moreover modified to apply a polynomial spatial warp to the surroundings of each iris in the represented image, which warp is such as to cause these surroundings to accommodate the movement of the pupil and iris of the corresponding eye.
