Patent Images
1. A wireless communications device comprising:
- a housing;
a microphone integrated with the housing to capture a user'"'"'s voice;
a camera integrated with the housing to capture images;
a transceiver in the housing to transmit the user'"'"'s voice and the captured images in a half-duplex mode to a remote party; and
a push-to-talk actuator integrated with the housing to trigger the microphone to capture the user'"'"'s voice, and to trigger the camera to capture the images responsive to the user depressing the push-to-talk actuator.

Abstract
A hand-held wireless communications device, for example, a cellular telephone, comprises a housing, a microphone to capture a user'"'"'s voice, a camera to capture images and/or video, a transceiver to communicate with a remote party in a half-duplex mode, and a push-to-talk actuator. A controller detects an operational state of the push-to-talk actuator, and activates the microphone, the camera, and the transceiver based on the operational state.

15. A method of transmitting voice and image data to a remote party via a wireless communications network comprising:
-
establishing a push-to-talk communications session with a remote party over a wireless communications network;
detecting operational state of a push-to-talk actuator integrated with a housing of a wireless communications device, the operational state including a depressed state and a released state;
activating a microphone integrated with the housing to capture a user'"'"'s voice responsive to detecting the push-to-talk actuator being in the depressed state;
activating a camera integrated with the housing to capture an image responsive to detecting the push-to-talk actuator being in the depressed state; and
transmitting the user'"'"'s voice and the captured image in a half-duplex mode to the remote party responsive to detecting the push-to-talk actuator being in the depressed state. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)
