Latest Patents

One of David Dearn's latest patents is an optical touch screen with a lossy dispersive FTIR layer. This touch-sensitive screen arrangement features an optically dispersive base plate and structures that transmit light onto the base plate. When an external body touches the screen at a specific point, the location of the incident light on the surface of the base plate indicates the relative position of the touch point. The base plate captures and disperses the incident light, with the decrease in light intensity approximating a substantially exponential function. A sensor detects the intensity of light at the edge of the base plate, allowing the arrangement to calculate the relative position of the touch point and generate a control signal representative of the control input derived from that position.
