Computer method and apparatus manage requests to make changes to a given software system. The power switch is so avoided to operate at highest gate and drain voltages simultaneously even a non-uniform turn on happens, and is thereby away from avalanche breakdown. A support which has a standard mini-card format is provided with a cavity having the dimensions of the device with a reduced format. Such a handle configuration can facilitate positioning of the teeth of the comb substantially flat against or parallel to the scalp, which makes removal of lice and nits more effective. The method further includes attaching a plurality of hair strands including at least one of natural hair and synthetic hair to at least one support member, and spirally wrapping the at least one support member around at least one of the first end, the middle, and the second end of the member. Data associated with identified transient events may be filtered from or otherwise removed from a given signal.
