Abstract:
A method for generating information regarding a 3D object from at least one 2D projection thereof. The method includes providing at least one 2D projection (40) of a 3D object, generating an array of numbers (50, 60) described by: aijk = vi'bik - vj''ajk (i,j,k = 1,2,3), where ajk and bjk are elements of matrices A and B respectively and vi' and vi'' are elements of vectors v' and v'' respectively, wherein the matrices (50) and vectors (60) together describe camera parameters of three views (102) of the 3D object and employing the array to generate information regarding the 3D object (70).
Abstract:
A multi-room air conditioning system (10) comprising a controller (90), a compressor (87), a first heat exchanger (30) in refrigerant fluid communication with said compressor (87), a second heat exchanger (40) in refrigerant fluid communication respectively with said first heat exchanger (30) and said compressor (87), said second heat exchanger also being in heat exchange communication with a stream of air (73), a plenum (50) arranged to receive said stream of air downstream of said second heat exchanger, a plurality of air flow ducts (66, 68) for distributing said stream of air from said plenum to a plurality of rooms (62, 60) a plurality of fans (74, 76), each fan associated with one of the plurality of air flow ducts, a plurality of motors (80, 82) each motor drivingly associated with one of said plurality of fans, at least one temperature controller (91) located in at least one of said plurality of rooms, and wherein said controller (90) is operative to selectively control a speed of rotation of at least one of said plurality of motors at least partially in response to a signal from said at least one temperature controller.
