Abstract: What is disclosed is a novel device and method to manage displays in a device with a camera. In one example, a first display is on a first side of the wireless device and a second display along with a camera is on the second side of the device. A facial detector detects a presence of a human face in an image captured by the camera. A power control circuit turns on the first display and/or second display in response to receiving a signal from the facial detector that a human face is detected. In a further example, a matching algorithm is used to determine if the human face in front of the camera matches a previously stored human face. In response to a match being found, an image associated with the previous stored human face is presented on the second display.

Abstract: A communication device (100) having a receiver circuit (110), signal processor circuit (120), controller circuit (130), either embodied by integrated circuits or on a single integrated circuit. The transfer of signals between the circuits is timed so as to minimize the effects of noise introduced into any one of the circuits, particularly the receiver circuit (110). The center of a symbol of a received RF symbol is detected and, through hardware control or software control, the transfer of a data signal generated by the signal processor circuit (120), for example, is permitted to occur only during a period(s) of time determined to have minimal effects on the sampling of a symbol in a received signal by the receiver circuit (110).
