Patent CA-2275662-A1 (CA)
Inventor: TRUMP TONU
IPC: H04M1/60
Filed: 1997-12-12
Abstract: A double talk and echo path change detector is provided for use in an echo canceller that makes a determination about whether a residual signal is dominated by echo or by a "near end" signal. In order to make this determination, a first measure of linear dependency is computed between the residual signal and an echo estimate, and a second measure of linear dependency is computed between the residual signal and a desired signal. The two results are compared with each other, and if they are of about the same order, no further action is needed. However, if the comparison determines that the dependence between the residual signal and the desired signal is much stronger than the dependence between the residual signal and the echo estimate, the present detector assumes that double talk has been detected and a signal denoting that result is output. On the other hand, if the dependence between the residual signal and the desired signal is much weaker than the dependence between the residual signal and the echo estimate, the detector assumes that an echo path change has been detected and a signal denoting that result is output. As such, a reliable and computationally effective method and apparatus are provided to give the echo canceller useful information about double talk and echo path changes that have occurred.

Abstract: A work platform (48) is supported by a sleeve (46) which is movable along a tower (40) having a plurality of vertically equally spaced rungs (45). The raising system (50) of the invention comprises two hydraulic rams (52), pivotably attached to the sleeve (46) and equipped with corresponding hooks (58) at the extremity of their piston rods (52a). The rams (52) are activated simultaneously in up and down movement but in alternate directions, bearing in a hooking engagement in turn on the rungs (45) of the tower (40) to pull the sleeve (46) upwards along the tower (40). When a rung (45) is in the path of a hook (58) in the upward movement, the latter pivots backwards to clear the rung (45) and is pivoted back by means of springs (66). The lowering operation of the sleeve (46) is done similarly to the raising operation, but there is provided latch levers (82) that an operator must unlatch to allow springs (86) to pivot the hooks (58) in a rung clearing position during the retraction of the corresponding ram's piston rod (52a), so that the hook (58) will clear the rungs (45).

Title: Biological waste treatment process and apparatus
Inventor: COOPER LINDY TY
IPC: C02F3/04
Filed: 1999-12-16
Abstract: An apparatus for wastewater treatment, includes a calorie reducer first vessel having an inlet and an outlet, the outlet adapted to control the retention time of wastewater within the first vessel. A first recycle pump is connected to the first vessel to recycle wastewater from a bottom of the first vessel to a top of the first vessel through a recycle conduit, at a high velocity. The recycle conduit provides an air gap for drawing air into the first vessel. Bacteria within the calorie reducer vessel consume biodegradable food with a minimum number of bacteria while in the log growth phase. A second bio-reducer vessel is connected to the calorie reducer vessel. The bio--reducer holds a media supported above a bottom reservoir. A bio-reducer recycle pump recycles wastewater within the reservoir to be sprayed onto a top of the bio--reducer, to wash over the media. Further bio-reducers can be arranged downstream of the first bio-reducer. In the bio-reducers, protozoa attached to the media consume the bacteria which wash over the media.
