A novel sundial system that uses fibre optics to display the time remotely. The system comprises a "sensor unit" placed in direct sunlight and a "display unit" located indoors, linked by flexible fibre optic cables. The sensor unit utilises a lens to focus sunlight onto a screen fitted with fibre optic ends positioned at five-minute intervals. These fibres transmit light to the display unit, which shows a moving point of light on a circular screen resembling a clock face. The system includes adjustments for latitude and Summer Time, and an extra fibre provides a double spot indication on the hour. The editor adds that this optical design, based on Benoy's patent, can indicate time even in hazy conditions and offers improved accuracy and contrast.
