摘要: Apparatus and methods can include an optical waveguide coupled to a photonic crystal comprising a dielectric material, the photonic crystal located on an exterior surface of the optical waveguide and comprising a first surface including a first array of periodic features on or within the dielectric material, the array extending in at least two dimensions and including an effective dielectric permittivity different from the surrounding dielectric material. In an example, the periodic features include a specified lattice constant, the periodic features configured to extract a portion of propagating optical energy from the waveguide through the photonic crystal, the portion determined at least in part by the specified lattice constant.

摘要: An insulated heating-unit cover having an opening to permit air to circulate around the heating-source when a vent disposed at the top of the cover is opened, allowing heat into a space. The cover can include a heating-unit temperature sensor disposed within a space covered by the cover and a controller in wireless communication with a space temperature sensor located at a distance away from the heating-unit. The controller can be configured to operate an actuator such that the vent is open when the space temperature sensor indicates that the ambient temperature is below a set point temperature and such that the vent is closed when the ambient temperature is greater than the set point temperature. The controller can communicate with a plurality of other similar controllers and a central server to effect changes in the output of a central heating source coupled to a plurality of individual heating-units.
