摘要:
A cold weather breathing device that protects the face including the mouth and nostril area from direct exposure to the external environment, prevents a user's goggles from fogging in cold environments, and keeps moist exhaled breath away from the user's face. In a preferred embodiment, the device is configured to provide separate breathing channels for exhaled air from the mouth and nose. To promote ease of cleaning, the breathing device can be attached to a head garment with a simple interlocking design that allows its removal and separate cleaning. The breathing device provides a nose-channel-forming member and mouth disc that are mounted on the head garment and inset into a mouth-channel-forming member which is thus attached to the head garment.

A method, system and apparatus for testing an integrated circuit chip. The system including: means for forming a liquid polyalphaolefine layer on a bottom surface of the integrated circuit chip, a top surface of the integrated circuit chip having and a bottom surface not having signal and power pads; means for placing a surface of a heat sink into physical contact with the bottom surface of the polyalphaolefine layer; means for electrically coupling the integrated circuit chip to a tester; means for electrically testing the integrated circuit chip; means for electrically de-coupling the integrated circuit chip from the tester; means for removing the heat sink from contact with the polyalphaolefine layer, all or a portion of the polyalphaolefine layer remaining on the bottom surface of the integrated circuit chip; and means for removing the polyalphaolefine layer from the bottom surface of the integrated circuit chip.
