Abstract: Disclosed is a brassiere having breast cups configured with inflatable bladders specifically positioned and configured to manipulate the breast tissue of a target breast into a lifted position whilst simultaneously displacing laterally sideways/outward and downward a contra-lateral breast. The brassiere is configured to lift the target breast away from the chest wall and to stabilise the breast so as to increase treatment accuracy and reduce radiation dosage to high risk organs such as the heart and lung. The brassiere according to the subject invention is advantageous to be worn by women for the treatment of either the left or right breast whilst providing modesty during treatment delivery.

Abstract: Computer implemented methods of compressing and decompressing image data are described. A discrete cosine (DCT) transformation is applied to each of a plurality of pixel blocks to generate a set of DCT coefficients for each pixel block comprising a DC DCT coefficient and a plurality of AC DCT coefficient. Each set of DCT coefficients is quantized. A DC array is formed from the set of quantized DC OCT coefficients and an AC matrix is formed from the set of quantized AC DCT coefficients. The AC matrix is compressed by eliminating blocks of data having only zero values and forming a reduced AC array from blocks including non-zero values. The reduced AC array is compressed using a key to form a coded AC array. The DC array and coded AC array are arithmetically coded to form arithmetically coded data which is included in a compressed image file. The decompression method is essentially the reverse process.

Abstract: A respiration monitoring device configured to provide quantitative data output of respiration cycles of a human or animal. The device may be configured to output a respiration rate and/or a respiration waveform expressed as temperature verses time. The device comprises a temperature modifier to heat or cool a flow of exhaled air. This heated or cooled air then flows past a temperature sensor to determine a temperature change associated with each exhaled air cycle.

Abstract: A PVD coating is disclosed, and in particular a nanoscale multilayer superlattice PVD coating comprising high hardness, a low friction coefficient and increased chemical inertness. The multilayer coating comprises a repeating bilayer represented by (VxMe(i-x))CyN(i-y)/(MezV(1-z))CyN(i-y) where 0.1?x?0.9; 0.01<y<0.99 and 0.1?z?0.9 and Me is a substantially pure metal or a metal alloy. The composition of the coating through the layers alternates from layer to layer according to a V-rich layer and a Me-rich layer modulated sequence. Vanadium is incorporated within the layer composition and has been found to act as a lubricating agent during sliding wear. Carbon, also incorporated within the coating, serves to further stabilize the friction coefficient thereby increasing the chemical inertness between cutting tool and workpiece material.
