Abstract: A holographic HMI allows data and commands to be entered into electronic equipment. The HMI involves no tangible physical contact between the human operator and the control elements because the input devices are holographic images of keys or other customarily touch-activated tangible input elements. Operator interaction is detected through electromagnetic means, obviating the need for direct physical contact with any solid input object or surface. Such HMIs generate a holographic image of a tangible input object of the tangible control mechanism. An illumination device illuminates the hologram to produce the holographic image. An actuation detection device detects the selection by the operator of a holographic image, and a signal generator receives the detection of the actuation detection device and provides an input signal to the electronic or electro-mechanical device thereby to produce the response. The hologram is affixed to a transparent or translucent material.

Abstract: A facade system for concealing a thermostat housing including: a hinge being selectably positional in at least first and second positions; and, a cover adapted to be coupled to the hinge; wherein, when the hinge is positioned substantially adjacent to the thermostat housing and coupled to the cover, the hinge and cover cooperate to facilitate access to the thermostat housing when the hinge is in the first position and to substantially conceal the thermostat housing when the hinge is in the second position.

Abstract: A holographic HMI is described by which data and commands can be entered into computers and other electronic equipment. The holographic HMI involves no tangible physical contact between the human operator and the control elements of the HMIs because the input devices are holographic images of keys or other customarily touch-activated tangible input elements. Operator interaction with those holographic images is detected through electromagnetic means or other means, obviating the need for direct physical contact with any solid input object or surface. Such holographic HMIs comprise a hologram for generating a holographic image of a tangible input object of the tangible control mechanism for the electronic or electro-mechanical device. An illumination device illuminates the hologram to produce the holographic image.
