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 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 applys 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 unit verification method to be performed on a unit under test (UUT) comprises connecting a verification device to the UUT. The verification device applies a set of challenge signals to the UUT and then measures the responses of the UUT to the challenge signals. The responses of the UUT are based on the challenge signals and the physical properties of the UUT. A registration key is generated based on the measured responses and is stored. The registration key is unique to the UUT.

Abstract: A phased array antenna comprises an array of reflective cells, each cell being defined by a wall positioned within the array the wall arranged to define a waveguide, and having a moveable reflector positioned within the wall. Each reflector is arranged such that it is not in electrical contact with its respective wall and such that, in use it can be moved to tune the antenna. A feed and subreflector are positioned within the array and arranged to transmit and/or receive electromagnetic signals to and/or from the array.

Abstract: A liquid droplet production apparatus comprising a perforate membrane and an actuator. The actuator is configured to vibrate the perforate membrane such that a liquid in contact with the perforate membrane during use is caused to pass through at least one aperture of the perforate membrane and to be ejected as liquid droplets from the perforate membrane. The perforate membrane includes one or more stiffening structures for increasing the stiffness of the perforate membrane, the one or more stiffening structures each being defined by a local transverse deformation of the perforate membrane. A removable cartridge, a perforate membrane, an actuator assembly for use in such a liquid droplet delivery apparatus, and a method of manufacturing a perforate membrane for such a liquid droplet apparatus.

Abstract: An aerosol delivery system includes a perforate membrane comprising a plurality of apertures, as well as a fluid reservoir reservoir in fluid communication with a first side of the perforate membrane and actuation means configured to vibrate the perforate membrane to cause a liquid in the fluid reservoir during use to be ejected as liquid droplets from a second side of the perforate membrane. The plurality of apertures comprises first and second arrays of apertures of first and second configurations which are grouped together in first and second discrete regions of the perforate membrane. The fluid reservoir includes first and second reservoir portions and a liquid barrier by which the first and second reservoir portions are separated. A removable cartridge for an aerosol delivery system.

Abstract: A droplet dispenser comprises a chamber (3) with a fluid inlet valve (2) and a fluid outlet valve (4). The chamber (3) is arranged such that the volume of the chamber may be varied in use to cause fluid to be alternately drawn in to the chamber (3) through the inlet valve (2) then subsequently expelled from the chamber through the outlet valve (4) to dispense a droplet. The droplet dispenser is capable of dispensing from an open reservoir and one may change the dispensed drop volume simply and easily. The droplet dispenser can also handle liquids which are normally seen as difficult to dispense, such as cyanoacrylate adhesives.

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.

Abstract: A sample preparation cartridge for use with a sample preparation device, the cartridge includes a housing defining plural separate segments, at least one of said segments comprising a fixed section of a pipette component; and a moveable head comprising a pipette tip, the head being configured, in use, to be moved between a position in which the pipette tip is in sealed engagement with the fixed section of pipette component and a position in which pipette tip is positioned adjacent to another of said plural segments. With the present invention a disposable sample preparation cartridge and corresponding analytical reader can be provided in a very cost effective and simple manner.
