Patent number: 7797843Abstract: An optical sight comprises an elongate housing defining a light channel. A lens is provided at one end of the light channel and has a partially reflecting surface. A laser diode is energised by a pulsating electric current delivered by a battery powered energising circuit, and the energised laser diode emits light towards the reflecting surface to produce a light spot by direct imaging of the laser diode on the surface. The light spot shall be superimposed on the target when sighting through the light channel from the other end thereof.Type: GrantFiled: March 7, 2000Date of Patent: September 21, 2010Assignee: GS Development ABInventors: Valerie Anne Scott, Alan Edward Green, Euan Morrison

Publication number: 20090291758Abstract: One embodiment of the invention provides a method of televising a card game. Each playing card in the card game has a value. The method includes providing the back surface of each playing card with a marking that is substantially invisible to the naked eye. The marking indicates the value of the playing card. An infrared detector is used to access the marking to identify the value of a playing card involved in the card game. Visual information indicative of the identified value of the playing card is generated and included in a broadcast of the card game.Type: ApplicationFiled: May 30, 2006Publication date: November 26, 2009Applicant: IKNOWLEDGE LTD.Inventors: Kevan Moretti, Nick Bryan, Alan Edward Green, David John Stocks
