Patent CA-2219478-C (CA)
Inventor: WILLEN DENNIS E
IPC: G01V1/28
Filed: 1996-06-13
Granted: 2000-11-28
Abstract: A frequency domain method (figures 3A & 3B) of processing geophysical data on a computer (18) having massively parallel processors (2). The method involves assigning data slice partitions to each processor (46), precomputing a velocity model corresponding to the geophysical data (72), and migrating the data on each slice within each processor using a one-pass, split wave equation finite difference technique for depth migration (50, 54) and either phase shift (230) or recursive techniques for time migration. A sequence of transforms and stranspositions (160) between processors assigned partitions on each frequency slice transforms into the frequency-wavenumber domain and allows the migration calculations to be directly performed by each processor to be independent of each other processor. The transforms and transposes also allow for depth migration error correction and filtering (184) in the frequency-wavenumber domain.

Abstract: Oil-in-water dispersions of .beta.-carotene and other carotenoids that are stable against oxidation, even in the presence of polyphosphates, especially sodium hexametaphosphate. These oil-in-water dispersions are typically prepared by contacting a water-dispersible beadlet comprising at least about 5 % colloidal carotenoid with the water phase to form droplets of the carotenoid that are in intimate contact with sufficient oil phase such that the carotenoid is stable against oxidation, even in the absence of an effective antioxidant such as ascorbic acid. The oil-in-water carotenoid dispersions of the present invention are especially useful in dilute juice beverages for providing vitamin A fortification and color, as well as other oil/water food and beverage products where vitamin A fortification and/or color are desired.

Title: Routing area update in packet radio network
Inventor: PUUSKARI MIKKO
IPC: H04B7/26
Filed: 1999-02-11
Granted: 2008-05-13
Abstract: A method of transmitting data in a packet radio network to a mobile station (MS) performing a routing area update. The packet radio network transmits data (2-0, 2-3a) to the mobile station (MS) via a first support node (SGSN,).  The mobile station (MS) sends a routing area update message (2-1) to a second support node (SGSN2) which sends to the first support node (SGSN,) a request (2-2) for context data (2-5) of the mobile station from the first support node. The first support node sends the requested context data of the mobile station (2-4), waits for a predetermined period of time (3-b), and sends additional data to the second support node (3-c). The predetermined time (3-3b) may be fixed, depending preferably on the quality of service of the connection used by the mobile station. Alternatively the predetermined period of time expires when the second support note (SGSN2) sends to the first support node (SGSN,) a separate acknowledgement message indicating that the second support node has received the context data of the mobile station.

Title: Shorting rings in dual-coil dual-gap loudspeaker drivers
Inventor: BUTTON DOUGLAS J
IPC: H04R9/04
Filed: 1999-03-19
Granted: 2006-02-07
Abstract: Loudspeakers and other transducers of the dual-voice-coil/dual-magnetic-gap type can be improved by the addition of one or more annular shorting rings (16A-16S) strategically located in the vicinity of the two magnetic gaps. The shorting rings have no effect on a steady state magnetic field but act in opposition to any change in flux density or any displacement of the flux lines such as those that occur under the loading imposed when the voice coils (10A, 10B) are driven hard with audio frequency current. Thus a plurality of rings can be strategically deployed at different locations so as to optimally suppress both even and odd order harmonic distortion and to reduce the voice coil inductance.
