Abstract: A computational device energizes, at different times, a first set of display elements in a display in accordance with differing values and/or display parameters in response to differing energy management requirements.

Abstract: A radiocommunications terminal includes a send circuit and a receive circuit connected to a send/receive antenna of the terminal and respectively defining, when in operation, a send mode and a receive mode. The terminal also includes a circuit in a common part of the connection of the send and receive circuits to the antenna for matching the send and receive circuits to the antenna. A device for controlling and monitoring the power of signals sent/received by the terminal decenters the impedance matching of the antenna of the terminal only when the device is in send mode. Applications include reducing the energy impinging on the user of a mobile radio communications terminal.
