摘要:
A golf club system has at least one golf club shaft assembly and a plurality of detachable golf club head assemblies. The golf club shaft assembly includes a shaft segment, a grip, and a coupler. The golf club head assembly includes a golf club head, a head shaft segment, and a head coupler pin to reversibly mate the golf club head assembly to a golf club shaft assembly to make a golf club. Any one of the golf club head assemblies can be attached to the golf club shaft assembly using a coupler. A second coupler allows the at least one golf club shaft assembly to be split into an upper shaft segment and a lower shaft segment to reduce the size of the golf club system. The golf club system can include a golf bag to hold the at least one shaft and plurality of detachable golf club head assemblies.

Spectral tuning of heat source to emit radiation at a desired frequency or frequency band is accomplished using metamaterials. The metamaterials include a structured geometry having holes with dimensions and spacing chosen such that the resulting surface will emit radiation in the desired spectrum. A collector can be made of a similar metamaterial or antenna array to detect the emitted radiation and transfer it to a converter device that converts the detected radiation to electricity. Embodiments also provide efficient coupling to the converter device for energy harvesting. Cooling of the converter devices can be accomplished using a cooling sink or deep space.

摘要:
A substrate, resonant structures, a ground plane, a thermal optimization layer and energy transfer structures are combined to receive and convert incoming electromagnetic radiation into electrical energy. This combination of materials may be housed in various configurations near heat sources to maximize surface area for heat contact as well as cooling. All structures are designed so as to be manufactured in low cost processes such as roll to roll.
