Abstract: A physically unclonable function (PUF) device comprises a plurality of optical fibres, at least some of which are arranged such that they are optically coupled. A media surround at least a portion of the optical fibres and at least one light source is configured to transmit light through one or more of the optical fibres. There is provided at least one light sensor configured to receive the transmitted light from one or more of the optical fibres and provide an output. Circuitry applies a challenge signal to at least one of the fibres using at least one light source and receives the output from the at least one light sensor, using the output to generate an identifying response to the challenge signal. The fibres are arranged such that the identifying response is unique to the device.

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.

A feeding line is provided to carry RF signals of two orthogonal polarizations from the input port P1, and at least one antenna feed element with an aperture or cross section having an order of symmetry C4 and supporting RF signals of two orthogonal polarizations is provided. At least one first substrate contains a plurality of antenna elements integrated into the substrate, with each antenna element capable of operating at two orthogonal polarizations. A plurality of phase shifters are connected to corresponding antenna elements, each phase shifter operating at two orthogonal polarizations, the output port of each phase shifter being connected to a short circuit.

Abstract: There is provided a sample ejection system for ejecting a sample from a flow of fluid, the system comprises: a fluid flow channel for receiving, in use, the flow of fluid; a fluid inlet channel connected to the flow channel and arranged to receive, in use, pressurised fluid; a fluid outlet channel connected to the flow channel at a location downstream in the flow direction of the flow of fluid and comprises an outlet. The system is arranged such that, in use, pressurised fluid is applied to the fluid flow channel via the fluid inlet channel to drive fluid from the region of the fluid flow channel between the fluid inlet and outlet channels through the fluid outlet channel and out of the outlet.

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.
