Abstract: A method and system for calibrating a measurement from a shoe-based sensor device for measuring pressure at one or more parts of a shoe sole and providing at least one pressure sensor measurement signal indicating the measured pressure, the method being performed at a processor that receives the at least one pressure sensor measurement signal and including: determining a minimum value for the at least one pressure sensor measurement signal and storing the determined minimum value as a correction constant in a data memory associated with the processor; and correcting a value for the at least one pressure sensor measurement signal received subsequent to the step of storing, by the stored correction constant.

Abstract: A method and system for measuring at least one metric associated with foot-based movement include: receiving at a processor a plurality of sensor measurement signals for a foot, each pressure sensor measurement signal indicating one or more pressure measurements taken at a respective, different part of the foot during movement; and computing, at the processor, the at least one metric associated with foot-based movement based on a combination of the received at least three pressure sensor measurement signals from the foot.

Abstract: A magnet assembly for use in carrying out nuclear magnetic resonance experiments on a body or sample. The assembly comprises a set of superconducting coils within a cryostat, located about a bore, and arranged to generate a substantially uniform magnetic field in a primary working volume within the bore, and to generate a substantially uniform magnetic field in a secondary working volume within the coil structure and separate from the bore. At least part of a hyperpolarisation system intersects the at least one secondary working volume so as to hold a sample to be hyperpolarised in the secondary working volume.

Abstract: Magnet apparatus (2) is provided comprising a magnet chamber (20), a magnet (2) positioned within the magnet chamber (20) and a quantity of superfluid coolant (30) which partially fills the magnet chamber (20) such that at least part of the magnet (2) is cooled by a superfluids film (31) of the coolant.

Abstract: A magnet assembly for use in carrying out nuclear magnetic resonance experiments on a body or sample. The assembly comprises a set of superconducting coils (12) within a cryostat, located about a bore, and arranged to generate a substantially uniform magnetic field in a primary working volume (101) within the bore, and to generate a substantially uniform magnetic field in a secondary working volume (100) within the coil structure and separate from the bore. At least part of a hyperpolarisation system intersects the at least one secondary working volume (101) so as to hold a sample to be hyperpolarised in the secondary working volume.

Abstract: A cryostat assembly includes a thermal shield, a cooling system including a cold member maintained in use at a temperature lower than that of the thermal shield, a first adsorption pump assembly located at least partly within the thermal shield, a first switch thermally connecting the adsorption pump to the thermal shield, a second switch selectively, thermally connecting the adsorption pump to the cold member, and a first thermal link. The first adsorption pump includes a pumping chamber containing a working fluid and an adsorption pump in fluid communication with the pumping chamber. The first thermal link couples the pumping chamber to the cold member. During adsorption of the working fluid by the adsorption pump, a portion of the working fluid evaporates so as to cause the temperature within the pumping chamber to fall below the temperature of the cold member.

Abstract: A cryogenic flow valve system for controlling the flow of a cryogenic fluid is disclosed. The system has a valve and an adsorption pump. The valve includes a flow chamber and a moveable member. The cryogenic fluid flows the flow chamber, and the moveable member is in contact with a control fluid. The position of the moveable member controls the flow in the flow chamber. The pressure of the control fluid controls the position of the moveable member. The adsorption pump includes a chamber and a heater. The chamber is in contact with the moveable member and contains an adsorption material for retaining control fluid. The heater heats the adsorption material to control the pressure of the control fluid.

Abstract: An adsorption refrigeration system and method are provided, the system comprising an adsorption pump which, in use, is arranged in communication with a chamber containing liquid and gaseous coolant. The associated method comprises expanding the gaseous coolant into an auxiliary volume member so as to cause the removal of part of the gaseous coolant from the chamber. This causes a reduction in the temperature and pressure of the gaseous coolant in the chamber. The adsorption pump is then operated so as to further cool the chamber by causing the evaporation of the coolant liquid within the chamber.
