Abstract: A method of operating a master control device includes obtaining, at a input-output interface, first measurement data for a zone of a physical space based on signals from a first group of presence sensors covering the zone of the physical space, obtaining, at the input-output interface, second measurement data for the zone of the physical space, based on signals from a second group of presence sensors covering the zone of the physical space and identifying, based on the first or second measurement data, one or more moving objects within the zone of the physical space. The method further includes associating, each of the one or more moving objects with an object class, determining, for each of the one or more moving objects, a track within a coordinate system for the physical space and outputting, a signal associated with the one or more determined tracks.

Abstract: A grip for holding a tablet computer in one hand while activating and using the device with the other hand comprises a stem connecting a base portion attached to the tablet and a top portion, with a central hole of appropriate size in the stem to accommodate a finger inserted through the grip. Opposing walls of the stem are biconcave in the plane perpendicular to the plane of the hole in the stem, defining a shape convenient for gripping between two fingers.

Abstract: The performance of electro-wetting displays can be improved by: (a) providing a concealment member (112) which conceals the moving fluid (108) when that fluid (108) is confined to a small area; (b) using the moving fluid to cover one or more sections of a filter or reflector having differently-colored sections; (c) moving the moving fluid between the rear surface and a side surface of a microcell; (d) using as a substrate for a moving fluid a substrate resistant to wetting by the fluid but pierced by multiple conductive vias capped with a material wetted by the fluid; and (e) coloring the moving fluid with pigments or nanoparticles.
