The present eyewear includes a pair of lenses, a pair of releaseable connectors connected to respective inner ends of the lenses, a pair of temples pivotally connected to respective outer ends of the lenses and a rigid strap connected between rear ends of the temples. The fuel vapor treatment system includes a fuel tank, a canister, a drain cut valve, a purge valve, purge piping and a sensor. A signal generator generates a drive waveform signal, that has a fundamental frequency, and the drive waveform signal drives the inverter system. The multiple pairs of leads are electrically coupled to the corresponding heaters respectively, and the heaters are respectively adjacent to the corresponding ink channels. Preferably, the ball and body member comprises an engineering polymer, such as a glass-filled thermoplastic material, while the toggle member comprises a polyolefin, such as a homopolymer or co-polymer polypropylene material. The housing is configured to conform to the shape of the statorrotorbobbin assembly so that a curtain of air can be concentrated onto the motor to enhance performance, safety and motor longevity.
