System and method for monitoring body movement

Drone Loading System

An unmanned aerial vehicle (UAV) 100 for transporting a payload 106 comprises a vehicle body and a retractable rail 105 exposed on an underside of the vehicle body. A retraction mechanism 104 coupling the rail to the vehicle body causes the rail to raise and lower relative to the vehicle body. A barrier 103 is located on the vehicle body so as to confront the rail when the rail is in its raised position to block the removal from the rail of a payload slidably engaged with the rail. The UAV may also provide a mechanism for advancing a payload onto and along the rail and pushing it off the rail. A method of loading and unloading a UAV, and a UAV comprising a payload carrier and latching mechanism are also disclosed.

Flexible circuit for detecting liquid presence

A flexible circuit 200 comprises two or more circuit layers 201, 202 separated by one or more insulating layers, one or more nodes 203-206 are located on each of the circuit layers, and a processor configured to estimate the distribution of liquid within the circuit from the electrical conductance measured at two or more of the nodes. The circuit may be used in clothing, dressings, or bandages to identify a liquid, pH or salinity. Distortion of the circuit may be measured from the measured parameters. Cardiovascular and other physical parameters may be determined. Stimulations and medicaments may be released from the circuit.

System and method for monitoring body movement

A method for determining the flexion or extension of a joint of a human or animal subject 502, comprising applying a plurality of strain gauges 504, 506, 508, 510, 512 to the joint in a known configuration, receiving strain data from each of the strain gauges, and calculating the flexion or extension of the joint in dependence on the received data and the configuration of the strain gauges. In another aspect there is a medical dressing comprising a strain gauge, measuring the strain applied to the dressing surface. An interface is configured to enable data from the strain gauge to be offloaded to an external system. A power management unit causes the interface to enter a reduced power mode in which data offload is reduced in response to detecting a predefined strain pattern. In another aspect the medical dressing comprises a strain gauge and first and second inertial measurement units (IMUs, 308, 310, fig.3), arranged at opposing ends of the dressing (206, fig.3). A controller (202, fig ...

Media playback system

A media playback system 100 comprising a transmitter 102 configured to transmit an indication of a media item; a plurality of drones 104; a controller 108 to control the spatial configuration of the drones 104 and, in response to receiving the indication, to control the drones 104 to adopt a predefined 3D spatial configuration. The system 100 further comprises a mobile device 110 comprising a camera 112 and a media playback unit 118, wherein the camera 112 is capable of capturing an image of the drones 104; a processor 114 configured to analyse the image to determine the media item that corresponds to the predefined spatial configuration; and wherein the media playback unit 118 is configured to play the media item. The position of the mobile device 110 may be used to determine a playback time of the media item. Further aspects disclose a location estimation system defining intended movements of a plurality of drones 104 and configured to receive an image and correlate the image with a projection ...
