20110139004 | SPRAY DRYER ABSORPTION PROCESS FOR FLUE GAS WITH ENTRAINED COARSE PARTICLES - Disclosed herein is a method for reducing the amount of coarser particles from a stream of flue gas prior to treatment by a spray dryer absorption process (SDA). The method comprises the steps of directing a stream of flue gas containing entrained particles of varying sizes through a curve, thereby subjecting the particles to a centrifugal effect, collecting the particles predominately of the coarser size at a particles collecting means provided in the outer circumference of the curve, dispersing the flue gas reduced in particles of coarse particle sizes into the chamber of a spray dryer absorption apparatus, wherein the particles content of the original flue gas stream is above 20 g/Nm | 06-16-2011 |
20130302229 | SPRAY DRYER ABSORPTION APPARATUS WITH FLAT-BOTTOMED CHAMBER - In the application a spray dryer absorption apparatus for treating a stream of flue gas containing acidic components is disclosed. The apparatus comprises a chamber having vertical cylindrical walls, said chamber comprises (i) an inlet for a flue gas stream containing an acidic component, (ii) an atomizer for spraying droplets of an absorbent slurry into said flue gas stream to effect a chemical reaction between the droplets and the acidic component of the flue gas, thereby forming a particulate reaction product, and (iii) an outlet for the treated flue gas and entrained particulate reaction product, wherein the bottom of the chamber having vertical cylindrical walls is substantially horizontal and impervious to gases. The apparatus of the invention has the advantage of a simplified geometry accounting for lower building and maintenance costs. | 11-14-2013 |
20140165627 | METHOD FOR CHILLING A BUILDING - A method for chilling a building includes the steps of: heating a working solution contained in a solar panel using solar radiation, separating the heated working solution in vapor and a concentrated working solution, condensing the vapor to liquid refrigerant, evaporating the liquid refrigerant, (i) in a building to be chilled or (ii) outside a building to be chilled, wherein the cooling obtained by evaporation is transferred to a cooling liquid outside the building and transported to the building to be chilled for delivery of the cooling, absorbing in an absorber the vapor in the concentrated working solution, and returning the working solution to the first step. | 06-19-2014 |

20100320840 | Method and Apparatus for Driving Low-Power Loads from AC Sources - Method and apparatus for providing controllable power to the load via AC-line power source where load is less than minimal required for proper operation of said source. In one example LED lamp connected to AC power source via conventional triac-based dimmer uses less power than minimum required for proper operation of said dimmer. In another example LED lamp connected to AC power source via device known as electronic transformer uses less power than required for proper operation of said electronic transformer. | 12-23-2010 |
20120248636 | HEATER UNIT HUMIDIFICATION CHAMBER MONITOR - A heater unit is adapted to determine if a humidification chamber thermally coupled to a hot plate of the heater unit is effectively dry based on determining a thermal response of a hot plate of the heater unit. Also, the activation period during which the hot plate is being heated is adjusted toward an optimum period by adjusting the energization or power level to the heater element thereof in relation to the duration of a prior activation period. Further, the air flow rate of gas through the humidification chamber may be estimated based on a temperature of the hot plate determined in predetermined relationship to the beginning of an activation period. | 10-04-2012 |
20140168443 | REMOTE SURVEILLANCE SENSOR APPARATUS - In a surveillance system including a remote sensor apparatus and a portable receiver, a method is provided for collecting and processing data related to a surrounding environment of the remote sensor apparatus including image data for a scene external to the housing of the apparatus. The method includes receiving, at the processing unit, raw image data simultaneously from a plurality of image sensors as the raw image data is being captured by the plurality of image sensors. One or more light sources are placed around a wide-angle lens fitted to each of the image sensor. Infrared or near-infrared light emanating from the plurality of light sources is used in a dark environment. The method also includes processing, at the processing unit, the simultaneously received raw image data to generate pre-processed image data. The method further includes transmitting the pre-processed image data to the portable receiver using the wireless transceiver. | 06-19-2014 |
20140266773 | REMOTE SURVEILLANCE SYSTEM - A method is provided for a system including a plurality of remote sensor apparatus and a portable receiver. The portable receiver includes an RFID reader. The remote sensor apparatus has an RFID unit. The method includes reading RFID stored in the RFID unit of one or more of the plurality of remote sensor apparatus using the RFID reader. The method also includes registering the one or more of the plurality of remote sensor apparatus using the received RFID. The method further includes receiving data from a first active remote sensor apparatus. The data includes sensor data collected from sensors installed in the first active remote sensor and RFID of the first active remote sensor apparatus. The method also includes processing the sensor data, if the RFID of the first active remote sensor apparatus matches the RFID of any of the one or more of the plurality of remote sensor apparatus. | 09-18-2014 |
20140267586 | SYSTEMS, METHODS AND MEDIA FOR GENERATING A PANORAMIC VIEW - A method is provided for a surveillance system including a remote sensor apparatus a portable receiver. The method includes receiving, at the portable receiver, image data collected simultaneously from a plurality of image sensors installed in the remote sensor apparatus. The method also includes processing, at the portable receiver, the received image data by, for each of the first plurality of captured images, detecting image features and performing feature matches by matching control points across neighboring images based on a control-point assumption that the control points are relevant only in areas of field of view overlap. The areas of field of view are determined by positions of the plurality of image sensors and a field of view of a wide-angle lens fitted with each of the plurality of image sensors. The method further includes generating a panoramic view by blending the processed first plurality of captured images. | 09-18-2014 |
