A network node discovery method allows multiple enumerators to concurrently accept and interpret the same enumeration responses from responder nodes on a network. The lensed fiber generates a Gaussian Beam and moves vertically with respect to the material. The grating includes a grating face surface that is in a grating plane. The thermoelectric cooling plate includes first and second electrical connections on opposite sides of the jaw member. In a specific embodiment, a GaSbAlSb buffer is utilized to form an InSb-based quantum well transistor on a silicon substrate. The boosting circuit includes: a first discharge circuit for discharging a voltage of a first output terminal when a boosting unit stops a boosting operation; and a second discharge circuit for discharging a voltage of a second output terminal.
