Patent number: 7099692Abstract: An infrared transceiver module for enabling a multiple direction infrared communication includes a transfer element for enlarging the working angles of infrared emission and reception of a transmitter and receiver portion. The transfer element has a surface area larger than the surface area of the transmitter and receiver portion. Infrared signal beam transmitting from the transmitter and receiver portion is repeatedly refracted by said transfer element and transmitted in multiple directions from the transfer element. Exterior signal beams coming to any portion of the transfer element are also repeatedly refracted by said transfer element and received by said transmitter and receiver portion. Therefore, a multiple direction infrared transmission and reception is obtained.Type: GrantFiled: May 22, 2003Date of Patent: August 29, 2006Assignee: Lite-On Technology CorporationInventor: Wen-Kuan Lin
