Patent CA-2350149-A1 (CA)
Title: Inflatable packer with feed-thru conduits
Inventor: TURLEY ROCKY A
IPC: E21B17/02
Filed: 2001-06-08
Abstract: An expandable packer provides a crescent-shaped cross-sectional area for more and larger diameter data cable and fluid control conduits by eccentrically offsetting the packer mandrel relative to the expandable element. The expandable element of the packer eccentrically surrounds the mandrel to provide an eccentric volume zone between the packer collars. One or more data cable or fluid carrier conduits may be laid between the collars within this eccentric zone, all of greater diameter than would be possible within an annulus between two concentric mandrels. The eccentric zone conduits are secured and protected by a compliant filler material such as rubber or other elastomer that is applied around and between the control conduits within the eccentric zone. This filler material is trimmed or cast to a substantially cylindrical surface about an axis that is substantially coextensive with the expandable element axis.

Title: Lumber trimmer
Inventor: HENDERSON DEANE R
IPC: B27B25/02
Filed: 2001-09-26
Abstract: A lumber trimming device for trimming elongate workpieces conveyed on an infeed conveyor in a laterally disposed orientation relative to an infeed direction.  The lumber trimming device includes a gang of laterally spaced apart drop saws wherein the drop saws are independently actuable according to generally optimized trimming instructions from an optimizer. At least on end-trimming saw is mounted adjacent the gang. The end-trimming saw or saws is or are selectively laterally translatable according to optimized end-trimming instructions from the optimizer so as to cooperate with the gang. The end-trimming saw or saws cooperate with the optimizer and the drop saws so that a first drop saw of the drop saws is actuated simultaneously with optimized lateral positioning of a first end-trimming saw so as to trim a first workpiece of the workpieces on the infeed conveyor simultaneously by both the first drop saw in a first trim cut and the first end-trimming saw in a second trim cut. Where a second end-trimming saw is employed, the first end-trimming saw cooperates with the optimizer to laterally re-position the first end-trimming saw subsequent to the second trim cut simultaneously with the second end-trimming saw actively laterally pre-positioning for an end trim cut on a second and next-adjacent workpiece on the infeed conveyor.

IPC: H02M7/49
Filed: 2002-04-15
Abstract: The circuit arrangement for transmitting real power from a DC voltage side to AC voltage-side connections has a first power converter (4) with load connections (5), in series with each of which second power converters (7) with a lower intermediate-circuit capacitor voltage are connected. This makes it possible to achieve finer voltage graduation of a sum voltage at the AC voltage-side connections (10). According to the invention, the second power converters (7) do not have their own real power supplies. There is thus no need for the previously used rectifiers for supplying the second power converters (7).      In the method according to the invention, voltages of intermediate-circuit capacitances of power converters (4, 7) and a common-mode voltage of the AC voltage-side connections of the circuit arrangement are regulated by means of joint regulation. The intermediate-circuit capacitor voltages are, in particular, kept essentially constant, although the second rectifiers (7) interchange real power with a load (11) and with the first power converter (4). To this end, a change in the intermediate-circuit capacitor voltages is calculated in advance using a model of the converter, and the common-mode voltage is selected such that a weighted sum of the squares of the errors between the intermediate-circuit capacitor voltages and the respective nominal values is minimized.

Title: Interference diversity in frequency hopping communications networks
Inventor: EDGREN ERIK
IPC: H04B1/713
Filed: 2000-07-31
Abstract: In a cellular radio telecommunications system that employs frequency hopping , system performance can be significantly improved by more fully exploiting interference diversity, while maintaining frequency diversity, which is already associated with frequency hopping techniques. In order to more fully  exploit interference diversity, each mobile station operating in a cell is allocated, in addition to a frequency hopping sequence, a frequency offset hopping sequence such that each mobile station hops from one frequency to th e next frequency as a function of the frequency hopping sequence and its allocated frequency offset hopping sequence. This technique is readily applicable to increase both intercell and intracell interference diversity i n unsynchronized or synchronizhed cells.
