Patent CA-2419849-A1 (CA)
Title: Filter structure with two or more layers of fine fiber having extended useful service life
Inventor: CROFOOT DOUGLAS G
IPC: B01D46/52
Filed: 2001-08-21
Abstract: The use of fine fiber of fiber having a fiber diameter of about 0.0001 to 0. 5 microns has become an important design tool for filter media. Common filter media have been prepared with a layer of fine fiber on typically formed the upstream or intake side of the media structure. The fine fiber increases the  efficiency of filtration by trapping small particles which increases the overall particulate filtration efficiency of the structure. Improved fine fiber structures have been developed in which a controlled amount of fine fiber is placed on both sides of the media to result in an improvement in filter efficiency but a substantial improvement in lifetime.

Title: Method and apparatus for determining available transmit power in a wireless communication system
Inventor: BAO GANG
IPC: H04B7/005
Filed: 2001-09-27
Abstract: Techniques to (more accurately) estimate the transmit power available for da ta service in a future time period (e.g., the next frame). In accordance with o ne aspect, variation in the available transmit power over time is estimated. A first margin is then computed and used to account for the estimated variatio n in the available transmit power. The available transmit power at a future ti me instance (e.g., the beginning of the next frame) is predicted and reduced by  the first margin to derive a more accurate estimate of the available transmi t power for the next frame. In accordance with another aspect, variation in th e required transmit power for a particular data user is estimated and used in scheduling data transmission to this data user. A second margin can be computed and used to account for the estimated variation in the required transmit power for the data user. Whereas the first margin accounts for variation in the (overall) available transmit power, the second margin is specific to the particular link conditions experienced by the data user.</SD OAB>

Patent CA-2458289-A1 (CA)
Title: Viscometer
Inventor: DRAHM WOLFGANG
IPC: G01N11/16
Filed: 2002-08-17
Abstract: The viscometer provides a viscosity value (X .eta.) which represents the viscosity of a fluid flowing in a pipe connected thereto. It comprises a vibratory transducer with at least one flow tube (13) for conducting the fluid, which communicates with the pipe. Driven by an excitation assembly (16), the flow tube (13) is vibrated so that friction forces are produced in the fluid. The viscometer further includes meter electronics (50) which feed an excitation current (i exc) into the excitation assembly (16). By means of the meter electronics (50), a first internal intermediate value (X1) is formed, which corresponds with the excitation current (i exc) and thus represents the friction forces acting in the fluid. According to the invention, a second internal intermediate value (X2), representing inhomogeneities in the fluid, is generated in the meter electronics (50), which then determine the viscosity value (X .eta.) using the two intermediate values (X1, X2). The first internal intermediate value (X1) is preferably normalized by means of an amplitude control signal (y AM) for the excitation current (i exc), the amplitude control signal corresponding with the vibrations of the flow tube (13). As a result, the viscosity value (X .eta.) provided by the viscometer is highly accurate and robust, particularly independently of the position of installation of the flow tube (13).
