    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 a plurality of temperature compensation particles are arranged throughout the media, where the temperature compensation particles have a temperature coefficient selected such that they compensate for temperature-related effects in the PUF device by making the permittivity and/or permeability of the media substantially temperature independent. Circuitry applies an electrical challenge signal to at least one or the conductors and receives 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 cartridge for an aerosol delivery system. The cartridge includes a fluid reservoir including a first reservoir portion, a second reservoir portion, and at least one liquid barrier configured to separate the first and second reservoir portions. The first and second reservoir portions have respective first and second openings at a first end of the cartridge. The cartridge further includes a perforate membrane located at the first end of the cartridge and over the first and second openings. The first and second openings are configured to supply first and second liquids to a first side of the perforate membrane during use and the perforate membrane comprises a plurality of apertures configured to eject one or both of the first and second liquids from a second side of the perforate membrane in the form of liquid droplets when the perforate membrane is vibrated. An aerosol delivery system includes the cartridge.

    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: An acoustic sensor, comprising: a side wall, closed by first and second end walls to form a substantially cylindrical cavity for containing a fluid, wherein a radius, a, of the cavity and an axial height, h, of the cavity satisfies the inequality a/h is greater than 1.2; a transmitter, operatively associated with one of the first and second end walls; a receiver, operatively associated with the other of the first and second end walls; and a first stiffener plate, comprising an outer peripheral edge and an aperture which defines an inner peripheral edge, and located on an outer face of the first end wall such that the aperture overlies the axis of the cavity; wherein: the first end wall comprises at least one through-hole, located radially of the axis of the cavity between the inner and outer peripheral edges of the first stiffener plate; the first stiffener plate comprises at least one duct, which connects the at least one through-hole, of the first end wall, to at least one of the inner and outer peripheral edges of the first stiffener plate, thereby to provide at least one fluid passageway between the cavity and the external surroundings of the acoustic sensor via the first end wall; and in use: the transmitter causes oscillatory motion, of the one of the first and second end walls with which the transmitter is associated, in a direction substantially perpendicular to the plane of that end wall, such that axial oscillations of that end wall drive substantially radial oscillations of a fluid pressure in the cavity; and the substantially radial oscillations in the pressure of the fluid drive oscillatory motion of the other of the first and second end walls, with which the receiver is associated, generating an electrical signal.

    Abstract: A counting mechanism (100) for a dispenser comprising: a first and a second housing part (110, 120) that are rotatable relative to each other; and a counting ring (130) disposed between the housing parts. The first housing part has a protrusion (111) which abuts the counting ring, holding a portion of the counting ring in contact with the second housing part. The relative rotation of the housing parts causes the protrusion to slide against the surface of the counting ring to drive a rolling movement of the counting ring around the circumference of the second housing part, such that a predefined rotation of the housing parts produces an incremental rotational displacement between the counting ring and second housing part to record a count. The counting mechanism provides a large gear reduction ratio in a compact form which is straightforward to manufacture and provides an accurate and reliable record of counts.
