ABSTRACT:
A wireless remote control transmitter for remotely controlling the operation of home entertainment devices. In one embodiment, the transmitter comprises a generally rectangular housing having a top end, a bottom end, a front, a back, a right side and a left side. An L-shaped printed circuit board is disposed within the housing, the board having a front portion and a right side portion. The printed circuit board includes a first LED adapted to transmit a beam of infrared light through a window in the top end of the housing, a second LED adapted to transmit a beam of infrared light through a window in the right side of the housing, suitable electronics and a printed circuit coupling the LED's to the electronics. A first keyboard, whose keys are accessible from the front of the housing, is positioned over the front of the printed circuit board. A second keyboard, whose keys are accessible from the right side of the housing, is positioned over the right portion of the printed circuit board. A second keyboard, whose keys are accessible from the right side of the housing, is positioned over the right portion of the printed circuit board. Depression of the keys of the first keyboard against the portion on the printed circuit on the front of the printed circuit board causes the first LED to emit appropriately coded signals through the top end of the housing. Depression of the keys of the second keyboard against the portion of the printed circuit on the right side of the printed circuit board causes the second LED to emit appropriately coded signals through the right side of the housing. The keys of the second keyboard preferably correspond to functions of the remotely controlled device that are most often controlled by users.
