    Abstract: A tactile overlay for a touchscreen includes one or more button structures, a flexible resilient membrane, and one or more nibs corresponding to the one or more button structures. The overlay is disposed over and in propinquity with the touchscreen display, with button and corresponding nib structure(s) of the overlay corresponding to virtual buttons that are displayed by the touchscreen display. The button structure(s) and corresponding nibs are positioned on the overlay so that a user can press a button structure, which causes the corresponding nib to touch a desired virtual button being displayed by the touchscreen display. The flexible resilient layer causes the nib to return to original position, breaking contact with the touchscreen display.

    Abstract: A fire retardant intumescent coating composition comprises: (a) 30 to 60% by weight of a phosphorous containing material which decomposes to produce phosphoric acid when the coating is exposed to fire; (b) 10 to 30% by weight of a thermosetting binder; (c) 2.5 to 10% by weight of a curing agent for the thermosetting binder; and (d) 5 to 40% by weight of a thermoplastic binder, wherein the active groups of the thermosetting and thermoplastic binders are chosen so as to impart charring and blowing functions to the intumescent coating composition. The thermosetting binder is advantageously a hydroxylated thermosetting binder, suitably an epoxy resin. The thermoplastic binder is advantageously an oxygenated heterocyclic thermoplastic binder, suitably an aldehyde and/or ketone resin. The coating composition may contain I to 10% by weight of a colouring agent, suitably titanium dioxide. The coating composition may contain 0.1 to 10% by weight of melt viscosity modifier, suitably hydrogenated castor oil.

    Abstract: A MEMS optical display system includes an illumination source for providing illumination light, a collimating lens for receiving the illumination light and forming from it collimated illumination light, and a microlens array having an array of lenslets for receiving the illumination light from the collimating lens. The converging microlens array directs the illumination light through an array of pixel apertures in an aperture plate to a microelectrical mechanical reflector array positioned opposite the aperture plate. The microelectrical mechanical reflector array includes an array of microelectrical mechanical actuators that support reflectors in alignment with the array of pixel apertures and selectively orients the reflectors to direct the illumination light back through the pixel apertures (to form part of a display image) or against the aperture plate (to be blocked). The illumination light passing back through the pixel apertures passes through the microlens array and a beamsplitter to a display screen.
