Simeonovo, ul. "74", No. 36Stolichna obshtina/oblast SofiaSofia This invention relates to a method and an apparatus for cleaning a flue-gas, which are applied in thermal engineering and in particular in thermal power plants and industrial enterprises with combustion installations. The apparatus for cleaning a flue-gas comprises horizontal absorber with absorption section (1) and gas-inlet conduit (5) on its one side, and outlet conduit (6) for cleaned gas, as in the lower end and longitudinal the absorption section (1) is implemented by areas (2.1, 2.2, 2.3, and 2.4) for solutions or suspensions. Between the individual areas (2.1, 2.2, 2.3, and 2.4) are located partitions (11), and at the end of the absorption section (1) separation section (3) and adsorption section (4) with outlet conduits (9.1, 9.2, and 9.3) are located next to each other. Absorption (1), separation (3) and adsorption (4) sections are mounted in a common housing (10), and inlet conduits (7.1, 7.2, 7.3, and 7.4) are provided to each zone (2.1, 2.2, 2.3, and 2.4 ) for supplying the absorbing agents in the relevant area, and outlet conduits (8.1, 8.2, 8.3, and.4) for product discharging after absorption. The outlet conduit (6) for cleaned gases is located after adsorption section (4).

[TODORIEV NIKOLA HRISTOV, HRISTOV HRISTO MARINOV, GANTCHEV RUMEN LYUBENOV, BONEV DRAGOMIR ENTCHEV] The vortexing apparatus has a flow divider and axles (7) immovably attached to a housing (1) by mounts, the axles having paddles (6) immovably mounted thereon. The flow divider is composed of a head (3) and an outlet part (4) which form a cavity (5). The head (3) of the flow divider carries a ring of radially arranged bracket bearings (9) in which the axles (7) are mounted, at the inner ends of which axles in the cavity (5) bevel gears (11) are attached, which mesh with at least one crown wheel (12). One of the axles (7) is connected at its outer end by a coupling (15) to a drive shaft (16) which passes through into the housing (1) in a sealed manner and is mounted in an external bearing (20). The drive shaft (16) is connected to a servomotor (23) via a lever system (22). At least one mount (2) of the flow divider is hollow. <IMAGE>

Each frame indicates a pattern of reflection at a particular time that corresponds to the frame. A trajectory generator receives the frame data and uses it to identify of a subject's trajectory through the space. An identification module identifies the subject based at least in part on the trajectory.

[Hristo Hristov, Rumen Peev, Kalin Petrov] BE Leper A 2-phase BLDC motor is driven by a trapezoidal waveform. For one-half of the motor rotation period T, the phase is driven by the trapezoidal waveform and for the other half-period, the coil remains undriven. An up down counter is operable to increment at a first frequency f1 and to decrement at a second frequency f2. Incrementing operation is initiated at the start of the driven period of the waveform and stopped at the start of the down slope of the waveform. Decrementing operation is initiated at the start of the down slope of the waveform and stopped at the end of the down slope. The ratio of frequencies f1:f2 is used to measure the relative duration of the slope to the driven period and is selected to mirror the desired ratio of slope duration:driven period duration.

[Yuqing Ai, Rumen Hristov, Dina Katabi, Bruce Maggs, Hariharan Rahul, Shichao Yue] US MA Cambridge Breathing signals are extracted from reflected wireless signals that are reflected from objects and/or people in a room. Feature maps are formed for the breathing signals at respective time intervals, each feature map representing a correlation of the breathing signals at each voxel in a plurality of voxels that represent three-dimensional locations within the room. The identity of the source of the breathing signals can be determined by statistically comparing the features maps with one or more location templates. Alternatively, at least some of the feature maps can be grouped into clusters. The distance between a respective cluster and a predetermined sleep area of at least one person can be used to identify the source of the breathing signals associated with the respective cluster.
