Abstract: Control of the operation of mobile communication equipment is provided in a power-off state, wherein a part of the mobile communication equipment is kept in operation for receiving and analyzing at least one of a set of excitation signals (VBAT, VCHAR, PWR_BTN, ALARM). Only a first part (30) of the mobile communication equipment, which essentially consists of timing means, is kept in operation continuously. A second part (29, 31, 32, 18) of the mobile communication equipment, provided for receiving and analyzing the signals, is controlled by means of the first part (30) to operate and analyze the signals during specified time intervals (t1), and to be inoperative at another time (t2). Power for a radio frequency (RF) transmitter and receiver of the second part is switched off during the power-off state. Analysis of the signals is accomplished during the power-off state.

Abstract: A start up charger and a method of providing an initial charge for a significantly depleted battery of a cellular phone is described in which the charging switch is cycled to provide a pulsed charge to the battery until said battery is charged to the operational voltage threshold of the cellular telephone controller.

Abstract: A start up charger and a method of providing an initial charge for a significantly depleted battery of a cellular phone is described in which the temperature of the battery is sensed and compared to a predetermined limit and further the battery condition is sensed and compared to preset conditions. If the battery temperature exceeds the temperature limit or the battery does not meet the preset conditions, the charging cycle is disabled.
