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: Method for producing an electrical impedance tomographic image of an acoustic field within a fluid, comprising the steps of: a) positioning a plurality of electrodes within a fluid; b) applying an electrical signal to each electrode within a first subset of electrodes, wherein the electrical signal applied to each electrode has a different carrier frequency and/or phase; c) measuring the electrical potential at each electrode within a second subset of electrodes, wherein the electrical potential is measured using a potential divider or a Wheatstone bridge; and d) processing the measured data to provide an acoustic map of the acoustic field at the required acoustic frequencies. There is also provided a system for producing an electrical impedance tomographic image of an acoustic field within a fluid using this method.

Abstract: A liquid droplet production apparatus comprising a separable perforate membrane (44), a means for supplying liquid to one side of the membrane, an actuator (41) for vibrating a membrane, so that the vibration causes liquid droplets to be ejected from the other side of the membrane, in which a magnetic force is used to connect the actuator to the membrane so that the vibration can be transmitted, wherein the magnetic force is generated by one or more arrays of magnets (43), eventually on a substrate (42), each array containing either a plurality of magnets or at least one magnet having a multiple pole configuration.

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: A receiver for a lidar system. The receiver comprises a monolithic block of optically transmissive material, the block shaped to define a planar light receiving surface, a first reflective surface and a second reflective surface positioned adjacent to the light receiving surface. The surfaces are positioned such that light from a distant on-axis source passing through the light receiving surface passes through the block to the first reflective surface and is reflected thereby towards the second reflective surface and in turn reflected thereby to pass through a receiving aperture formed in the first reflective surface and to come to a focus at or after the receiving aperture.
