Patent CA-2259609-A1 (CA)
Inventor: FERTNER ANTONI
IPC: H04B3/23
Filed: 1997-07-08
Abstract: In a digital communications system, a sampled signal is precisely reconstructed (rather than approximated) even in situations where the phase of the sampling signal is adjusted. More particularly, the sampled signal is compensated in the frequency domain for phase adjustements to the sampling instance in the time domain. In the context of echo cancellation, an echo transfer function is generated representing the echo channel impulse response. Aliased components present in the echo impulse response are specifically identified and compensated for in the frequency domain by treating each spectral filter coefficient of the echo transfer function as the sum of a baseband component and an aliased component. In addition to accurately compensating for sampling phase adjustments, this technique considerably relaxes traditional sampling constraints.

Patent CA-2279778-A1 (CA)
Title: System and method for using precalculated strips in calculating scatter radiation
Inventor: SIOCHI RAMON ALFREDO CARVALHO
IPC: G06F19/00
Filed: 1999-08-06
Abstract: The present invention relates to a fast and accurate method for calculating fluence of a calculation plane (210) over a patient. According to an embodiment of the present invention, only a subset (560, 562) of the collimator leaves (104) are analyzed for the fluence calculation, thus reducing the number of calculations required. Additionally, pre-integrated values of scatter strips (520), associated with each point of the calculation plane (210), may be referenced in a lookup table (1010). The use of these pre-integrated values allows the avoidance of adding the fluence contribution of each square on the scattering plane (202). Rather, pre-calculated values of a subset (560, 562) of the scattering plane (202) (scatter strip (520)) may be referenced and combined, thus reducing the number of calculations required for a final scatter contribution to a point (500, 500a, 500b, 500c) on the calculation plane (210). Further, the thickness of the collimator leaves (104) is considered in the fluence calculation, thus providing a more accurate model for the scatter contributions of points on the scattering plane (202).

Title: Isoflavone rich protein isolate and process for producing
Inventor: GUEVARA BALAGTAS F
IPC: A23J1/14
Filed: 1999-11-17
Abstract: A process for providing a isoflavone rich protein isolate is provided, along with the isoflavone rich protein isolate produced thereby. A vegetable material containing protein and at least one isoflavone compound is extracted with an aqueous extractant having a neutral pH. The protein and isoflavones are extracted into the extractant, and the extractant containing the protein and isoflavones is separated from insoluble vegetable materials to form a protein extract. The pH of the protein extract is adjusted to about the isoelectric point of the protein to precipitate the protein. The extract containing the precipitated protein is cooled to a temperature of from 30°F to 90°F, and then the protein is separated from the extract. The cool separation temperatures unexpectedly significantly increase the concentration of isoflavones recovered in the separated protein, while the neutral extract pH inhibits loss of protein normally observed at cool or cold separation temperatures.
