  • Patent number: 10986881
    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.

  • Patent number: 10432971
    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.

  • Publication number: 20140084151
    Abstract: A method of preparing a sample for matrix assisted laser desorption ionisation mass spectrometry imaging analysis by a two-step process. Firstly, a MALDI matrix is dusted on to the sample followed by a spray of a suitable solvent onto the dusted sample. The present method has been successfully applied to the detection and mapping of several analyte classes in latent fingermarks. Using the present two-step method, fingermark enhancement, recovery and analysis from different substrate surfaces is now possible enabling visual and chemical information to be obtained simultaneously via remote testing.

  • Patent number: 8173248
    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.
