Patent number: 6574209Abstract: Communication speed of a radio communication device such as a portable telephone is controlled according to temperature of a transmitting amplifier to avoid overheating of the device. The transmitting amplifier temperature is detected by a temperature detector installed in the device. When the transmitting amplifier temperature is lower than a first temperature, the communication speed is set at a high level to transmit both voice and image data. When the transmitting amplifier temperature exceeds the first temperature, the communication speed is automatically switched to a low level to avoid overheating of the device. Under the low speed communication, only the voice data are transmitted. When the transmitting amplifier temperature becomes below a second temperature that is lower than the first temperature, the communication speed is switched back to the high level to resume transmission of both voice and image data.Type: GrantFiled: August 16, 1999Date of Patent: June 3, 2003Assignee: Denso CorporationInventor: Akio Kosaka
