Abstract: The invention relates to a biofuel, particularly an advanced solid biofuel, comprising waste coffee grounds.

Abstract: A ring electrode design that produces a uniform mass sensitivity distribution across a TSM device is presented. A new technique and apparatus to measure this mass sensitivity distribution is also presented. Novel electrode geometries on thickness shear mode (TSM) quartz resonators achieve radial uniformity of mass sensitivity, how receptive the device is to mass loadings, and high frequency stability across the active sensing area of the sensor device. The device allows for absolute mass measurement down to the nanogram level. Fabricated devices utilizing model predictions were tested using this apparatus, and good agreement between theory and experiment is found.

Abstract: An air bubble detection system includes an air bubble detector which is disposed downstream from a syringe or manifold used during an angiography procedure. The air bubble detection system monitors contrast medium being injected into the patient and creates an alarm or other indication if the air bubble exceeds any desired threshold.

Abstract: A system for designing and ordering a stent graft is described. The system includes a user interface for designing and ordering the stent graft, and a centralised data processor remote from and in communication with the user interface for processing and storing entered information. The user interface further includes a selection portion for selecting a stent graft design and a design portion for entering a plurality of design parameters related to the stent graft design. A verification portion is also provided to verify details of a completed stent graft design with an ordering portion to order the completed stent graft design. In one embodiment the verification portion includes the capability to display a 3-dimensional view of the completed stent graft design.

Abstract: A mould assembly (60) and a method of use in injection moulding of a part having a functional cavity therein. The mould assembly has a recess (72) to receive a hollow tubular insert (48) intended to be placed in the mould assembly before the injection of a mouldable material into the cavity and to remain in the part after moulding. A gas supply arrangement supplies pressurised gas to the hollow tubular insert at a selected stage during the injection process whereby to form the functional cavity in the part.

Abstract: A wheel chair ramp comprises a plurality of leaves extending in the direction of intended use of the ramp. The leaves are joined together by flexible hinges so that the leaves may be folded to a stalked condition. The flexible hinges are formed by fabric straps attached to the sides of the leaves and passing between adjacent leaves.
