A microchannel device includes several mass transfer microchannels to receive a fluid media for processing at least one heat transfer microchannel in fluid communication with a heat transfer fluid defined by a thermally conductive wall, and at several thermally conductive fins each connected to the wall and extending therefrom to separate the mass transfer microchannels from one another. The brake bracket is mountable to a handlebar. A flexible thin film interconnect structure is formed over the first surface of the metal substrate and over the aperture. This is achieved by using a device as a navigation link essentially comprised of a grid-like component on which a plurality of measuring marks and a plurality of connecting elements each having a fastening device are attached. The linear voltage is utilized to control the operating speed of a direct current fan. The Gurley value of the foil is <250 s.
