Abstract: The present invention provides a device with a pressure control system and methods for controlling the application of negative pressure to an external surface of an individual for creating and/or maintaining patency of the upper airway passage. The device is configured to fit under the chin of a subject at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The pressure control system contains control module elements that may include circuit board elements, digital output barometer elements, sensor elements, processing elements and memory elements to optimize device function and safety of the device through regulation of the flow rate of the air pump.

Abstract: There is provided a sample preparation device comprising a sample preparation vessel and a bead manipulation mechanism for manipulating sample preparation beads in the vessel. The bead manipulation mechanism comprises: one or more magnets arranged to produce a magnetic field for manipulating, in use, one or more beads in the vessel. Each magnet is attached to a support frame by a biasing support arranged to support the magnet in contact against an outer surface of the vessel such that the magnet maintains contact with the vessel during relative movement between the magnets and the vessel.

Abstract: A sensing system for determining the location and orientation of an object which comprises a magnetic tag. The sensing system comprises selection coils and interrogation coils. The selection coils are arranged to generate a spatially-varying DC magnetic field from which the location of the tag can be determined in use. At least some of the interrogation coils are arranged to generate one or more AC magnetic fields and at least some of the interrogation coils are arranged to receive harmonics, intermodulation products or time dependent variations of the AC magnetic fields, from which the orientation of the tag is determined in use.

Abstract: A cap and seal system for a liquid medicament container. The system comprises a cap formed from a substantially rigid material and has a retention component integrally formed therewith. A seal is formed from a material which is less hard than the cap and positioned within the cap such that, when the retaining component retains the cap on a container in use the seal is positioned such that it forms a fluid tight seal between the cap and the container. A recess is formed in the seal through which a liquid outlet channel can pass in use to access the contents of the container via the cap and the seal.

Abstract: A physically unclonable function (PUF) device comprises a plurality of conductors, at least some of which are arranged so that they interact electrically and/or magnetically with one another. A media surrounds at least a portion of each of the conductors, and circuitry applies an electrical challenge signal to at least one of the conductors and for receiving an electrical output from at least one of the other conductors to generate an identifying response to the challenge signal that is unique to the device.

Abstract: A medicament delivery device for dispensing discrete doses of medicament comprises: first and second medicament carriers each comprising said doses of medicament contained in a plurality of individual compartments spaced along a carrier strip and sealed by a sealing layer; first and second opening mechanisms each arranged to handle a respective one of the first and second medicament carriers and to open each compartment of the respective medicament carrier by separating the sealing layer from the carrier strip as the medicament carrier is advanced through the device; a take-up spool arranged to wind the separated sealing layers thereon such as to maintain the separated sealing layers in tension, each separated sealing layer having a path of travel between a respective one of the first and second opening mechanisms and the take-up spool; and a tension control element in contact with each of the separated sealing layers, wherein at least a part of the tension control element is arranged to be movable by a biasing force, which is exerted on the tension control element by the separated sealing layers as a result of any inequality in the tensions of the separated sealing layers wound by the take-up spool, to alter the length of the path of travel of each separated sealing layer so as to substantially equalise the tensions in the separated sealing layers.

Abstract: An apparatus for inductive temperature sensing comprises a coil configuration, a target, and an impedance measurement circuit. The target has a non-zero conductivity and susceptibility and the impedance measurement circuit measures the apparent inductance of the coil configuration at a measurement frequency close to the crossover frequency to provide an indication of temperature of the target.
