Abstract: A power output circuit supplies an audio power output signal that is adjusted to prevent clipping when needed based on an estimate of available energy from the power supply supplying the power output circuit. The power output circuit may be an audio power output circuit that generates an audio power output signal from samples of an audio program that are stored in a buffer. A processing block determines an energy requirement for producing the audio power output signal from the audio program and adjusts an amplitude of the audio power output signal in conformity with the determined energy requirement and an available energy determined for the power supply so that the audio power output signal is reproduced without clipping of the audio power output signal.

Abstract: A broom and dustpan combination, the broom and dustpan being connected by a flexible cord. A grip associated with a locking member slides up the hollow shaft of the broom and is capable of being secured in a locked position. The cord is at least partially disposed inside the hollow shaft of the broom and is connected at one end to the locking member and at the other end to the dustpan. The dustpan is configured to mate with the handle of the broom when the locking member is secured in the locked position. When the locking member is disengaged from the locked position, the dustpan is capable of being lowered to the ground where it is ready to collect dust or debris swept inside by the broom.
