摘要： The present application relates to a pneumatic device for cleaning ventilation ducts, which includes a guiding air hammer, a turning conduit, an air-supply pipe and a slewing mechanism for the conduit. The guiding air hammer has a hollow spherical or hemispherical shape and is connected to the turning conduit. A cleaning fumarole and a guiding fumarole are provided on the rear arc wall of the guiding air hammer. When in operation, the air-supply pipe stretching means retracts and stretches the air-supply pipe, which enables the guiding air hammer to clean out the dust on the inner walls and in the corners of a ventilation duct without the need of an operator entering the ventilation duct. The air-supply pipe stretching means may be controlled by manual operation or program composition. The device may be used for cleaning ventilation ducts with a polygonal section.

摘要： An exemplary embodiment in accordance with this invention is a method for determining the number of interfering streams. The method includes calculating statistical information based on one or more received OFDM signals. The number of interfering streams is estimated from the statistical information in this method. The OFDM signal(s) are received via a plurality of antennas. Storing the OFDM signal(s) in a square matrix may be included in the method. A covariance matrix of the square matrix can be determined; and a noise subspace and a signal plus interference subspace can be determined based on a SVD of the covariance matrix. The statistical information may be based on the signal plus interference subspace. Apparatus, computer programs and computer-readable media are also disclosed.
