Abstract: An unmanned aerial vehicle (UAV) has: a body for carrying an article; at least one rotor; and a light source for generating a light beam to indicate the landing zone for the UAV. The UAV, in use, is flown to a desired location, that might be a site of an emergency with no defined landing zone. The UAV descends, and, while descending the light source is operated to illuminate and to define a landing zone. The UAV can be provided with lights and an audio source to warn and advise bystanders that the UAV is landing and to stand clear of the landing zone.

Abstract: A computer-implemented method and system are provided for generating an encoded representation for one or more images. The method involves operating a processor to, for at least one image portion of a plurality of image portions of the image, receive a set of projection data representing an image intensity of the image portion along a plurality of projection directions; and identify a subset of projection data from the set of projection data associated with one or more dominant features. The set of projection data includes a subset of projection data for each projection direction of the plurality of projection directions. The processor is operable to generate the encoded representation based at least on a data variation within the subset of projection data for the at least one image portion.

Abstract: Embodiments of the invention relate to systems and methods for multi-player gaming. Some embodiments relate to systems having an improved communications infrastructure and improved handheld game controllers, while other embodiments relate to improvements in handling large numbers of players in the multi-player game when played in a game arena with a single large display screen showing the multi-player game images. In one particular embodiment, a system is provided that has a game server controlling a display system to display the multi-player game on the large screen and a plurality of game controllers. Each game controller has a secondary display means for providing a secondary game display and input means for receiving player input. The system further comprises communication means for enabling communication between the game server and each of the plurality of game controllers. The plurality of game controllers are located in proximity to the large display screen such that it is visible to game players manipulating the game controllers while playing the multi-player game.

Abstract: The various embodiments disclosed herein relate to systems and methods for generating a derived media clip corresponding to a live event. In particular, the system comprises a processor configured to receive a plurality of content streams corresponding to the live event, each content stream corresponding to a content source. The processor is further configured to generate an annotated timeline for one or more of the plurality of content streams and receive a first user input requesting the derived media clip. The processor is then configured to generate the derived media clip based on the user input and the annotated timeline.

Abstract: A surface cleaning apparatus has a cyclone bin assembly having a cyclone chamber. The cyclone chamber with a physical filtration member defining the cyclone air outlet. The physical filtration member extends from the cyclone air inlet end of the cyclone chamber towards an openable bottom end of the cyclone chamber. The physical filtration member comprises a conical section which decreases in diameter towards the openable bottom end of the cyclone chamber, wherein a projection of the conical section meets at a location that is positioned between the physical filtration member and the openable opposed end. An openable bottom end of the cyclone bin assembly and the openable bottom end of the cyclone chamber are openable concurrently.

Abstract: The present disclosure provides a method of inducing a cross-protective immune response in a subject against a pathogen, such as influenza, comprising administering a first unique pathogen antigen to the subject; and administering a second unique pathogen antigen 3-52 weeks after a); wherein the second unique pathogen antigen and the first unique pathogen antigen are immunologically distinct but share conserved sites that are not normally immunogenic for antibodies. Also disclosed herein are assays for detecting cross-protective antibodies, methods of generating novel cross-protective antibodies. Further provided are novel antibodies against influenza.
