A heavy-duty hand-held power tool appliance includes at least one electric motor configured to drive a working tool and an energy storage unit configured to supply electricity to the at least one electric motor. The transmit probability may be used in transmitdiscard decisions of packets or instructions exercised at every arrival of a packet or instruction. If the number of processing cycles used during encoding exceeds the threshold, motion estimation techniques can be discontinued in favor of less computationally intensive encoding techniques such as texture encoding. This invention also relates to cowpea cultivars or breeding cultivars and plant parts derived from cowpea cultivar 95-104, to methods for producing other cowpea cultivars, lines or plant parts derived from cowpea cultivar 95-104 and to the cowpea plants, varieties, and their parts derived from use of those methods. The method continues by adjusting the gain of a second set of digital audio samples in the media stream using a steady state gain adaptation scheme that is different than the fast gain adaptation scheme, resulting in a second group of gain-adjusted digital audio samples having normalized volume during presentation.
