In management of power in a radio base station, a power allocation controller allocates a prescribed transmission power to a communication channel requested for set-up within an allocatable power range, and forgoes allocation of transmission power when allocation is not possible. The non-interruptible code portions prevent implementation of a real time interrupt that would corrupt the code so that execution could not be resumed. A plurality of spaced-apart electrodes are operably attached to the flexible body near the distal end.
