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 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: 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.

Abstract: A nozzle plate (201) for use in a liquid droplet production apparatus and such apparatus, the nozzle plate comprising a flexible substrate having a linear array of nozzles that extend through said plate, said nozzles being arranged in at least one line, forming thereby a nozzle-bearing region, wherein the substrate is curved so as to impart an increased longitudinal stiffness to it. The apparatus comprises a piezo actuator (202, 203), which may have slots (211) separating fingers acting on the nozzle plate (201). The nozzle plate may be separable form the actuator.
