Inventor: IRESON RICHARD LINNEY
IPC: G01V1/32
Filed: 1996-11-19
Abstract: The processing of surface seismic data may be monitored where vertical seismic profile data are available for the same region. A trace (45) of the vertical seismic profile data recorded from a geophone at the surface is compared with data generated by the data processing before completion of migration and provides a measure of the quality of the data processing. Alternatively, a derived trace may be derived by taking sections of the vertical seismic profile data traces along a section curve (47). The derived trace may be thought of as partially migrated data and may similarly be used for monitoring the quality of surface seismic data processing.

IPC: H04B7/26
Filed: 1996-05-01
Abstract: An apparatus and method for reducing interference between an uplink transmitter of a fixed satellite service (FSS) system (150) and an uplink or downlink receiver of a local multipoint distribution service (LMDS) system (100) are described. An ordered list of the preferred uplink transmission frequencies is assigned to all FSS uplinks located in a particular cell of the LMDS system (100). Different ordered lists are used in different cells (105-1 105-3) of the LMDS system (100), while uplinks located in the same cell can utilize the same order list. Further, the ordered list may be selected by the LMDS service provider such that the impact of interference from FSS uplinks can be readily predicted and minimized. Therefore, the system allows simultaneous access to a shared frequency band for both LMDS and FSS systems (100 and 150).

Patent CA-2251660-A1 (CA)
Inventor: KRAFT CLIFFORD H
IPC: G01N21/86
Filed: 1996-04-15
Abstract: L'invention porte sur un procédé et un appareil détectant la présence d'une goutte de liquide dans une chambre de réaction transparente ou d'autres surfaces réfléchissantes en présence de lumière ambiante et d'un mouvement passager de la chambre. Une source lumineuse (4) est modulée en deux ou plus de deux niveaux séparés selon un rythme de modulation fixe ou variable par un modulateur (3). Ces niveaux comprennent un niveau d'obscurité où la source ne produit pas de lumière. La lumière de la source est réfléchie sur un détecteur optique échantillonné au moins une fois pour chacun des niveaux de lumière modulée. Les différences entre les niveaux modulés et le niveau d'obscurité représentent le taux de réflectivité de la surface ou de la chambre. Lorsque du liquide entre dans la chambre ou est déposé sur la surface, la réflectivité change, ce qui entraîne des variations détectables entre les niveaux modulés et le niveau obscur. La lumière ambiante produit simplement un décalage de la valeur absolue des niveaux. Les différences d'amplitude sont comparées à des seuils pour permettre de déterminer si la réflectivité a suffisamment changé pour indiquer la présence de liquide. Si c'est le cas pendant trois ou plus de trois cycles complets de modulation, on peut attester la présence de liquide.

Patent CA-2253092-A1 (CA)
Inventor: BARMAN BRUCE G
IPC: A47C27/06
Filed: 1998-11-06
Abstract: A mattress employs a high density, high ILD convoluted polyurethane foam topper as a major transition layer over the supporting surfaces of an innerspring assembly in order to provide a smooth transition from the support characteristics of the padding and upholstery layers to the innerspring assembly. A high density, high ILD foam material of substantial thickness is positioned between a padding or insulating layer over the innerspring assembly and overlying upholstery, with convolutions in the high density transition layer oriented to extend away from the innerspring assembly. The high density transition layer dominates or masks the support characteristics of the innerspring assembly so that the perception of stiffness or board-like feel of an innerspring is greatly reduced upon initial loading of the mattress.
