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: A single junction sorter for a microfluidic particle sorter, the single-junction sorter comprising: an input channel, configured to receive a fluid containing particles; an output sort channel and an output waste channel, each connected to the input channel for receiving the fluid therefrom; a bubble generator, operable to selectively displace the fluid around a particle to be sorted and thereby to create a transient flow of the fluid in the input channel; and a vortex element, configured to cause a vortex in the transient flow in order to direct the particle to be sorted into the output sort channel.
