Abstract: According to embodiments of the disclosure, there is provided a device comprising: processing circuitry configured to: receive a polarised light image of an object at least in part made from polarising material; detect the outline of the object from the polarised image; determine the probability that the outline of the object is a stored outline; and on the basis of the determined probability being above a threshold; output a control signal indicating a positive match. In some embodiments the disclosure may provide for the sorting or distinguishing of plastic objects for manufacturing, recycling, reuse or repurposing.

Abstract: The present disclosure pertains to a circuitry for processing a target region configured to: determine a deviation in a scene based on background model data and current image data of the scene: determine a movement in the scene based on Doppler radar data of the scene; and determine a target region in the scene based on at least one of the determined deviation and the determined movement.

Abstract: A method of treating or preventing infection by an intracellular pathogen in a subject is described. The method includes administering to the subject a therapeutically effective amount of a composition including KH-1, KH-2, or a derivative and/or a pharmaceutically acceptable salt thereof. A method of treating or preventing bacterial inflammation in a subject is also described. New KH-1 and KH-2 derivatives are also described.
