摘要:
A method of localising a transportable apparatus (102) within an environment around the apparatus is disclosed. The method comprises obtaining a sequence of images (200) of the environment and generating one or more sequences of transformed images (204) from the sequence of images wherein an image from the sequence of images has undergone a transformation to provide a transformed image within the sequence of transformed images. Processing circuitry (112) is then used to compare one or more images from the sequence of transformed images (204) and one or more images from at least one of the sequence of images (200) and a further sequence of transformed images against a representation of the environment. The comparison determines corresponding features within the images (200) and/or transformed images (204) and the representation. The transportable apparatus (102) is then localised according to a position of the one or more corresponding features.

The present invention relates to a method for diagnosis of acute myeloid leukaemia comprising: i. contacting an isolated sample containing a blood cell population with a screen that detects at least the following cell surface polypeptide markers: CD34 + ; CD45RA + ; CD123 + ; and CD38 - ; wherein (+) indicates the presence and (-) indicates the absence of said cell surface polypeptide markers; and ii. confirming the presence of a blood cell that has a cell surface phenotype comprising: a. CD34 + ; b. CD45RA + ; c. CD123 + ; and d. CD38 - . Also encompassed are related methods for prognosis, identifying a therapeutic candidate, and monitoring efficacy of a therapeutic molecule.

A method of producing a localised concentration of energy includes: creating a shockwave propagating through a non-gaseous medium so as to be incident upon a boundary between the non-gaseous medium and a gaseous medium formed by at least one hole in a barrier separating the non-gaseous medium from a gaseous medium. This forms a transverse jet on the other side of the hole which is incident upon a target surface comprising a depression which is spaced from the barrier in the gaseous medium. An apparatus for producing a localised concentration of energy is also described.

Objects within a three-dimensional (3D) environment are detected by obtaining a point-cloud environment representation (e.g. from LIDAR) comprising a set of point locations, and converting the point-cloud to a 3D feature grid by dividing the 3D space into cells according to a grid size, determining whether the cells contain point-cloud points, and mapping any that do to a feature vector, and mapping any that do not to a zero feature vector. A detection window is also generated containing an integral number of the cells and having a set of positions which can be occupied. A detection score for each position is calculated by: voting for each cell within the window which includes at least one point, each vote being calculated using the cell feature vector (e.g. fixed-dimensional feature vector) and a weighting vector (e.g. obtained from a linear classifier), and summing the votes. The score provides a basis for determining whether each position contains an object of interest, each position with a score above a threshold being classified as containing an object of interest. The vote may comprise a scalar product of the cells feature vector and the weighting vector. A system performing the method may be provided on a vehicle.

A method of producing a localised concentration of energy includes: creating at least one shockwave propagating through a non-gaseous medium so as first to be incident upon a focusing pocket of fluid within the medium. The focusing pocket of fluid is positioned relative to a differently sized target pocket of gas within the medium, and is arranged to shield the target pocket of gas from the initial shockwave, such that the incidence of the shockwave on the focusing pocket of fluid concentrates the intensity of a shockwave subsequently incident upon the target pocket of gas. An apparatus for producing a localised concentration of energy is also described.
