Patent CA-2202284-A1 (CA)
Title: Blood processing system
Inventor: POWERS EDWARD T
IPC: A61M1/00
Filed: 1995-10-10
Abstract: A rotor (2a-2e) for collecting and centrifuging biological fluids in a range of volumes. The rotor includes an elastic impermeable diaphragm (31) which defines at least a portion of a variable-volume processing chamber (30), where the fluid is centrifuged. The rotor includes a rigid mounting member (28), to which the diaphragm is mounted and which is held and spun by a chuck. Preferably, this rigid mounting member includes a boundary wall (10) which together with the elastic diaphragm defines the chamber. The boundary wall may be a substantially imperforate circular wall which extends to the periphery of the processing chamber but defining one opening, preferably near the axis of rotation, permitting a conduit (13) or conduits (83, 93, 163, 165, 188) to pass therethrough so as to be in fluid communication with the processing chamber.      The rotor may include a separate structure (40, 190, 244) for controlling the flow of liquid out of the chamber into the conduit. In a preferred embodiment, this outlet-control structure is a perforate, substantially rigid wall or plate (40), located within the processing chamber and mounted adjacent the rigid boundary wall. In an alternative embodiment, the outlet-control structure for controlling flow from the processing chamber to the conduit may include at least one tube or preferably a set of tubes (190), wherein each tube provides fluid communication between the chamber and the conduit. In one preferred embodiment, grooves (244) in the boundary wall may be used as the outlet-control structure.

Title: Transmission of data items
Inventor: VAN GESTEL HENRICUS ANTONIUS W
IPC: H04N7/16
Filed: 1997-01-16
Abstract: An arrangement and method is disclosed for transmitting data items to a receiver for selective display on said receiver. The data items may collectively constitute an electronic television program guide or a database of products and services for electronic shopping purposes. By transmitting auxiliary presentation and navigation information, the informati on provider may determine how a receiver displays the data items and how the receiver needs to respond to user actions. Sometimes, however, it is desirable for a receiver to respond in a setmaker-defined manner, even if navigation and presentation data are provided by the setmaker. I n order to solve possible conflicts between the information provider's interests and the setmaker industries' interests, the tra nsmission includes a copyright bit which allows an information provider to indicate explicitly whether or not a receiver is allowed to ignore t he transmitted presentation and/or navigation data.

Patent CA-2233523-A1 (CA)
Inventor: SHIN HYUN-SOO
IPC: H04N5/44
Filed: 1998-03-30
Abstract: L'invention porte sur un récepteur pouvant recevoir des signaux TVHD et NTSC et sur une méthode de sélection des signaux reçus. Dans la méthode de l'invention, un mode de diffusion est choisi à l'extérieur. Quand ce mode est un mode NTSC, un signal NTSC est sélectionné. Quand c'est un mode TVHD, un signal à haute définition («ATV») est sélectionné. Quand le mode de diffusion examiné est un mode automatique, le récepteur de l'invention détermine si le signal reçu a une composante NTSC. S'il n'y a pas de composante NTSC dans le signal reçu, le signal ATV est sélectionné. S'il y a une composante NTSC dans le signal reçu, un canal choisi à l'extérieur est identifié. Si ce canal est un canal NTSC, le signal NTSC est sélectionné; si ce canal est un canal TVHD, le signal ATV est sélectionné. Les signaux TVHD et NTSC peuvent donc être reçus tous les deux et, quand un canal contient à la fois un signal NTSC et un signal TVHD, l'un ou l'autre de ces signaux peut être sélectionné.

The multiple zoom lens groups comprise a first zoom lens group of negative optical power that is axially movable, and a second zoom lens group of positive optical power that is axially movable and contains an optical stop or iris. The single auxiliary lens group is of relatively weak positive optical power compared to the other lens groups is axially stationary and contains at least one non-spherical, non-plano optically refractive surface. The remaining optically refractive surfaces of said zoom lens system being substantially spherical or plano. By axial positioning of said multiple focus lens groups and said multiple zoom lens groups, the zoom lens system provides a high level of optical performance at said real image through its entire and substantial focusing and zooming ranges.

Abstract: A noise reduction structure for a vehicle driveshaft assembly insures that each of the interior chambers of the driveshaft tube is properly vented during use. The noise reduction structure is a solid member having a predetermined length and a cross sectional shape which corresponds generally to the cross sectional shape of the driveshaft tube. Preferably, the noise reduction structure has an outer diameter which is approximately equal to, or slightly larger than, the inner diameter of the driveshaft tube. As such, the noise reduction structure engages the inner surface of the driveshaft tube in a light press fit relationship. Each noise reduction structure has a passageway, groove, or other opening formed therein which extends axially throughout its length. In a preferred embodiment, an axially-extending groove is formed on the outer circumferential surface of the noise reduction structure. The groove provides for free air flow from one end of the noise reduction structure to the other, thereby insuring that each of the interior chambers of the driveshaft tube is properly vented during use.
