1. A wireless power receiver system operatively associated with eyewear including a load, the eyewear comprising:
a front face;
a first arm connected to the front face via a first hinge, the first arm comprising a first receiver antenna and a first repeater antenna, wherein the first receiver antenna and the first repeater antenna are configured to receive wireless power signals from a wireless transmission system comprising a first transmitter antenna and a second transmitter antenna, and wherein the first repeater antenna is configured to transmit first repeated wireless power signals;
a second arm connected to the front face via a second hinge, the second arm comprising a second receiver antenna and a second repeater antenna, wherein the second receiver antenna and the second repeater antenna are configured to receive the wireless power signals from the wireless transmission system, wherein the second repeater antenna is configured to transmit second repeated wireless power signals, and wherein the first receiver antenna is configured to receive the second repeated wireless power signals and the second receiver antenna is configured to receive the first repeated wireless power signals;
wherein the first arm and the second arm are configurable to be folded inward toward the front face in at least a first folded configuration and a second folded configuration, wherein the first folded configuration comprises the first arm folded in closer proximity to the front face than the second arm, and wherein the second folded configuration comprises the second arm folded in closer proximity to the front face than the first arm, and
wherein, in the first folded configuration the second receiver antenna is configured to receive first wireless power signals from the first transmitter antenna, the second repeater antenna is configured to receive second wireless power signals from the second transmitter antenna, and the first receiver antenna is configured to receive the second wireless power signals via the second repeated wireless power signals transmitted by the second repeater antenna; and
wherein, in the second folded configuration the first receiver antenna is configured to receive the second wireless power signals from the second transmitter antenna, the first repeater antenna is configured to receive first wireless power signals from the first wireless transmitter antenna, and the second receiver antenna is configured to receive the first wireless power signals via the first repeated wireless power signals transmitted by the first repeater antenna.
