Abstract: Some embodiments are directed to a biometric authentication system including headwear having a plurality of biosensors each configured to sample muscle activity so as to obtain a respective time-varying signal, a data store for storing a data set representing characteristic muscle activity for one or more users, and a processor configured to process the time-varying signals from the biosensors in dependence on the stored data set so as to determine a correspondence between a time-varying signal and characteristic muscle activity of one of the one or more users, and in dependence on the determined correspondence, authenticate the time-varying signals as being associated with that user.

Abstract: A method and apparatus for autonomous control of unmanned aircraft. A method includes, in a memory of a flight controller associated with an unmanned aircraft, identifying a target to be captured, the identifying comprising a plurality of target variables, identifying a type of the unmanned aircraft, selecting one or more capture routines, defining desired data parameters, and storing the plurality of target variables, the one or more capture routines and the desired data parameters in the memory as a flight path.

Abstract: The present invention provides a combination of a door and door frame defining a door opening. The door frame comprises a horizontal header beam. The door opening has a horizontal top side and a horizontal bottom side, with the horizontal header beam defining the horizontal top side. The door comprises a top panel, a middle panel, a bottom panel, a first horizontal hinge member, a second horizontal hinge member and a third horizontal hinge member, each panel having a horizontal upper edge and a horizontal lower edge. The door is in the closed position when the top panel, the middle panel and the bottom panel are vertically aligned with one another and hanging downwardly from the horizontal header beam in a vertical plane of the door opening, with the horizontal upper edge of each panel above the horizontal lower edge of each respective panel, and the horizontal lower edge of the bottom panel is located in the lowermost position proximate to the horizontal bottom side of the door opening.
