Abstract: The present invention relates to methods of forming metal-pyridine derivative complexes using pericyclic reactions with metal-1,2,4-triazine derivative complexes and a dienophile as the reactants. The reactants are bioorthogonal and the methods are particularly useful in preparing imaging agents.

Abstract: There is provided a kit of parts for assembly into an impactor (100) for aerosol component collection, such as for exhaled breath. The kit of parts is configured such that an impactor component (128) is receivable into the assembly such that, when a sealing component (136) is in a sample collection configuration and an aerosol sample is being received at an aerosol inlet (110) of a housing of the kit, in use, an aerosol flow path (124) of the aerosol sample is directed onto an impaction surface (130) of the impactor component (128) to promote aerosol deposition thereon. The kit of parts is further configured such that the sealing component (136) is changeable in the assembly into a sample containment configuration before removal of the impactor component (128) from the assembly, so as to retain any aerosol components deposited on the impaction surface (130).

Abstract: A method of tracking an object. The method comprises imaging a marker on an object surface using a depth imaging camera, said marker comprising a three-dimensional pattern; generating a representation of the marker; matching the representation of the marker to a representation of a reference three-dimensional pattern in a reference orientation; comparing the representation of the marker to the representation of the reference three-dimensional pattern, and thereby determining a position and orientation of the object relative to the camera.

Abstract: A composite machining tool includes a tool body with at least one cutting edge and at least one grinding region. The grinding region is located adjacent to the cutting edge such that there is a gap between the grinding region and the cutting edge and such that when the tool performs a machining action the cutting edge and the grinding region act together on a material surface.

Abstract: Positioning apparatus comprises: a first surface; a tubular body having a longitudinal axis and a first end surface at a first end of the tubular body, the first end surface being arranged in contact with the first surface; and surface wave generation means arranged to generate a first travelling surface wave on the first end surface, the first travelling surface wave travelling along a first portion of the first end surface in a first direction around the first end surface, and, while the first travelling surface wave is travelling along the first portion of the first end surface, to generate a second travelling surface wave on the first end surface, the second travelling surface wave travelling along a second portion of the first end surface in a second direction around the first end surface, the second direction being opposite to the first direction.

Abstract: A hand-held device (10), comprising a computing application of the hand-held device which responds to directional commands of a user; an image registering unit to register a series of images; an image processing unit (162) to derive motion data from the series of images corresponding to translational and/or rotational movement of the hand-held device in free space; and a direction control unit (164) to convert the motion data into a directional command and to supply the directional command to the computing application.

Abstract: A microwave holographic measuring method is disclosed. A first electrical signal S of microwave frequency is provided. A first part S1 of the first signal S is directed to a first antenna (101). Predetermined changes of phase and amplitude are applied to a second part S2 of the first signal S to produce a second electrical signal S4 which is coherent with the first part S1 of the first signal S. Microwave radiation is detected at a plurality of locations by means of a second antenna (107) to generate a third electrical signal S5 at each location. The second S4 and third S5 electrical signals are combined to produce a fourth electrical signal.

Abstract: A device for positioning a patient for surgery. The device is used with an operating table, and includes two arms for resting on the operating table, a patient support, and a lifting mechanism arranged to move the patient support between a first position in which the patient support lies level with the operating table, and a second position above the table. The patient is rolled onto the support in the first position, and is then raised to the second position.
