    Abstract: In accordance with a first aspect of the present invention, there is provided an ambient backscatter circuit arranged to generate a varying circuit reflection coefficient. The ambient backscatter circuit comprises: a modulation member; a switching device in electrical communication with the modulation member; a first load having a first load reflection coefficient in communication with the switching device; a second load having a second load reflection coefficient in communication with the switching device; and an antenna terminal in communication with the switching device. The modulation member comprises: a baseband processor; and a chirp spread spectrum generator. The baseband processor is configured to generate a signal plan. The chirp spread spectrum generator is configured to generate a modulation signal based on the signal plan. Finally, the switching device is configured to switch, based on the modulation signal, between: the first load; and the second load such that the load reflection coefficient changes at the antenna terminal according to the modulation signal.

    Abstract: A contrast element tracking method comprises obtaining a sequence of frames each comprising ultrasound or other medical imaging data representing an anatomical region of a human or animal subject at a respective different time; for each frame, identifying one or more portions of the ultrasound or other medical imaging data as single or multiple contrast element signal portions representative of a contrast element or plurality of contrast elements; assigning respective position data to each of the single contrast element signal portions and each of the multiple contrast element signal portions; and using a linking model that uses at least said assigned position data to link single or multiple contrast element signal portions represented in at least one of the frames to single or multiple contrast element signal portions represented in at least one other of the frames thereby to track movement of contrast elements through said region of the subject.

    Abstract: A gripper for handling objects is provided. The gripper comprises a body (12) containing a drive mechanism, and a pair of arms (18,20). Each arm (18,20) comprises a proximal arm member (22) rotatably connected to the body (12), and a distal arm member (24) rotatably connected to the proximal arm member about a first axis of rotation. Each arm (18,20) also has a link drive member (68) rotatably connected to the body (12), and a proximal link (84) arranged within each proximal arm member (22). The proximal link (84) has a first end connected to the link drive member (68), and a second end connected to the distal arm member (24) at a location offset from the first axis of rotation. For each arm (18,20) the drive mechanism rotates both the proximal arm member (22) and the link drive member (68) relative to the body (12).
