    摘要: An oven for heating, cooking, or toasting a food product. The oven can comprise a conveyor for conveying the food product, and a parabolically shaped top surface with a plurality of reflectors connected thereto, to direct heat back toward the conveyor. The oven can also comprise a fan for circulating air within the oven cavity. The oven can also comprise a controller that can place the oven in an energy savings mode, when it detects that the oven is not in use. The controller can place the oven in energy savings mode by adjusting the speed of, or shutting off the conveyor, or by adjusting the amount of energy supplied to heating elements disposed within the oven.

    摘要: An exemplary WDM coupling device may include optical fibers. The coupling device may also include region(s) having varying coefficients of thermal expansion. During a temperature variation, one or more of the region(s) may alter in size to substantially cancel temperature-dependent changes associated with the WDM coupling device.
