Abstract: A bladeset for a hair clipper includes blade teeth configured to guide hair strands toward a cutting zone and to retain hair strands in the cutting zone. By more effectively guiding and retaining the hair strands into the cutting zone, more complete hair cutting may be achieved. Another feature of the present self-cutting hair trimmer is a housing configured to provide a cutting line associated with a generally elongate handle, which in turn provides a bladeset angle of attack substantially perpendicular to hair to be cut on all parts of a self-user's head or a subject's head when the present trimmer is held by a user in either hand.

Abstract: The present invention relates to a method and apparatus for selectively receiving radio frequency (RF) signals which utilizes an array of antenna elements including a center antenna for receiving the RF signal, a navigational controller using coordinate information to determine pointing vectors pointing to respective RF signal sources, and beam-forming electronics connected to the array of antenna elements and the navigational controller for forming reception lobes. Each reception lobe points in the direction of a determined pointing vector. For accurate and precise measurements, a constant phase center is maintained by adjusting the center antenna to the same phase shift for each of the lobes and steering the lobes by adjusting the phase shift of the antenna elements surrounding the center antenna.

Abstract: A cord wrap for use with a clipper is provided. The cord wrap accommodates a power cord associated with the clipper and has at least one retaining structure for retaining the power cord on the clipper. Provided on the at least one retaining structure is a cord channel which supports at least one loop of the cord.

Abstract: A hand-held comb has a set of fine teeth and a set of coarse teeth joined by a center section. The center section preferably has an opening large enough for a finger. The fine teeth and coarse teeth extend in opposite directions away from a longitudinal axis. Some or all of the teeth can have at least one undulation, to remove loose hair and at least some of the teeth can have barbs, to remove partially cut hair strands. The teeth can have sharp edges, which also remove partially cut hair strands.
