Inventor: SCHREUDER JAMES D
IPC: H04L12/24
Filed: 2003-11-05
Abstract: The present invention is directed to the measurement of service levels provided by a communication network, including an Internet protocol communication network. In accordance with the present invention, test packets are sent from a first edge muter across the communication network to a second edge muter. The time required for the test packets to be transmitted across the communication network is then determined, and that time compared to the time specified by the governing service level agreement. A failure of the communication network to deliver test packets as guaranteed may be used as an indication that the service level agreement has been violated. Packet loss and packet fitter may also be measured and compared to levels guaranteed by the service level agreement. The present invention may be used to determine whether the delivery of data packets using requests for expedited service levels is necessary or desirable.

Title: Architecture de circuit de transmission permettant de reduire le bruit intrabande dans des systemes de communication point a multipoint
Inventor: SHIELDS NICHOLOS PAUL
IPC: H04B7/005
Filed: 2002-06-27
Abstract: L'invention concerne un nouveau système de communication point à multipoint sans fil permettant de porter au maximum le nombre de stations distantes pouvant communiquer avec une station de base. Ce système est conçu pour commander de manière indépendante le gain de l'émetteur situé dans les stations distantes en fonction de la distance séparant la station distante de la station de base. La commande du gain peut être effectuée par des affaiblisseurs faisant partie du circuit de transmission RF des stations distantes. Ces affaiblisseurs peuvent être disposés juste en amont des amplificateurs RF dans le circuit de transmission RF des stations distantes. La quantité d'affaiblissement réalisée par les affaiblisseurs peut être commandée par un microprocesseur. La minimalisation du gain des émetteurs situés dans les stations distantes permet de minimaliser le bruit de fond du récepteur de la station de base et ainsi d'accroître la performance de ce dernier. Grâce à cette augmentation de performance, plus de stations distantes peuvent communiquer avec la station de base.

Title: System and method for synthetic aperture radar mapping a ground strip having extended range swath
Inventor: TSUNODA STANLEY I
IPC: G01S13/90
Filed: 2003-12-22
Abstract: A system and method for mapping a ground strip having an extended range swath includes a synthetic aperture radar (SAR) mounted on a moving platform. The ground strip is divided into columns they extend from the near-range edge of the ground strip. Each column contains two or more portions and has an azimuthal length equal to the radar's near-range beamwidth, W.     Each column is sequentially illuminated while the platform moves through a distance, L illum, (equal to the near range beamwidth). During column illumination, portions within the column are sequentially mapped by altering the depression angle, .phi., of the radar beam. Each portion is SAR mapped using a respective SAR apertur a length with the sum of aperture lengths for the column being less than or equal to the distance the platform moves during illumination. The resultant maps are mosaicked together to produce one contiguous SAR map of the ground strip.

Patent CA-2455691-A1 (CA)
Inventor: DYMENT BOB
IPC: B28C7/06
Filed: 2004-01-23
Abstract: The present invention is directed to an apparatus used for loading concrete components through a loading hopper of a mixing truck. It comprises a substantially vertically-disposed cement discharge pipe substantially centered within the discharge hopper. A water inlet is also provided in the discharge hopper. An aggregate feeding mechanism having an outlet above the discharge hopper allows providing aggregates to the mixture. This apparatus is less vulnerable to congestion since cement falls directly into the mixing truck and is encapsulated in the other concrete components. It also provides less and possibly no airborne dust particles because of encapsulation. Overall, the apparatus and the corresponding method provide an increase in flow and discharge of concrete components, thereby allowing faster loading of mixing trucks.

IPC: G05D23/13

Abstract: By means of a temperature measuring device (34) and a throughflow measuring device (32) which are both connected to a regulating unit (16), the mixing temperature of the mixing water flowing through a supply line (32) and the throughflow are determined.        The regulating unit (16) serves for controlling a mixing valve (14) and a shut-off valve (38). So that, at the end of the filling operation, the overall volume introduced into a container (22) and input via a control apparatus (18) has the likewise input desired temperature, the regulating unit (16) continuously determines, on the basis of the throughflow and the measured mixing temperature, since a starting time point, the actual heat quantity contained in a part volume which has already flowed out. By virtue of this determination, and based on the desired heat quantity to be stored in the respectively predetermined overall volume in the case of the predetermined desired temperature, if appropriate, the regulating unit (16) causes the mixing temperature to be increased or reduced by changing the mixing ratio between the hot water supplied to the mixing valve (14) via a first supply line (58') and the cold water supplied via a second supply line (58).

Abstract: A simple yet effective method of increasing production of a thermo-stable virus, such as adenovirus and picornavirus, is presented. The method entails a temperature shift strategy whereby the culture of host cells are shifted to a sub-optimal temperature for a period of time prior to virus infection or cells are grown at a sub-optimal level for the entire cell expansion process including one or more than one passages of cell growth from cryopreserved cells, followed by a shift back to a more optimal temperature at or near the time of virus infection of the respective host cells. Adaptation of such a temperature shift strategy present a simple yet effective method to substantially increase recoverable virus within a respective host cell/virus production scheme without the need to further manipulate other culture and/or media conditions within an established host cell / virus production scheme.
