Abstract: An attachment comb is provided for a hair clipper, and includes a comb body having a leading edge and an attachment edge, a blade-engaging surface and an opposite outer surface, and a plurality of teeth projecting from the leading edge. Sidewalls on the comb body project from the body, and at least one of the sidewalls defines a magnet opening. The blade-engaging surface has a magnet recess located adjacent a corresponding magnet opening, the magnet recess defining a magnet pocket. A magnet has a peripherally projecting base flange and is constructed and arranged for insertion through the magnet opening and such that the flange is insertable into the recess and the magnet is disposed in the magnet pocket so that a blade contacting surface of the magnet is in direct contact with a corresponding clipper blade upon assembly of the comb upon a clipper blade.

Abstract: An apparatus for comminuting biological specimens includes a receiving component provided with a drive source, a sample retainer configured for retaining at least one biological specimen and for engagement in the receiving component, and a single use comminution mechanism in operational relationship with the sample retainer. The drive source is configured for driving the comminution mechanism. A collector is associated with the receiving component for receiving comminuted product generated by the comminution mechanism. A method for comminuting biological specimens is provided so that, upon comminution, the specimen is readily subject to rapid extraction and detection of drugs and their metabolites, compounds, chemicals, pesticides, steroids, growth enhancers, contaminants or other pharmacologic agents which may reside in the specimen.

Abstract: A hair clipper assembly configured for attachment to a user's clothing, including a battery pack having a housing at least one battery, a belt clip, and a holster recess; a holster having a holster belt clip; a hair clipper configured to slidably fit within the holster; and a cord connecting the clipper to the battery pack.

Abstract: A blade calibration gauge for a bladeset for a hair cutter has a moving blade laterally reciprocating relative to a stationary blade, where the moving blade and the stationary blade are adjustable relative to one another in a direction normal to a direction of reciprocation. The blade calibration gauge has a base defining a recess configured for receiving the stationary blade and providing a first stop for engaging a toothed edge of the stationary blade, and a second stop on the base disposed relative to first stop for providing a designed offset spacing for a toothed cutting edge of the moving blade relative to the corresponding toothed edge of the fixed blade.

Abstract: An apparatus for comminuting biological specimens includes a receiving component provided with a drive source, at least one sample retainer configured for accommodating at least one biological specimen and constructed and arranged for engagement in the receiving component. The sample retainer includes a first component configured for receiving a specimen prior to comminution and a second component for receiving the specimen after comminution. In addition, the sample retainer is insertable into the receiving component as a single piece.

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.
