    Abstract: This application provides a wireless power transfer unit, device, and method. The wireless power transfer unit includes a radiation source, a light-emitting body, a controller, and a metasurface. The radiation source is configured to emit an electromagnetic wave signal. The controller is configured to control the light-emitting body to provide light sources of different light intensities. The light-emitting body provides the light sources of different light intensities in response to control of the controller. The metasurface is configured to perform phase adjustment on the electromagnetic wave signal that is incident to the metasurface. Equivalent impedance of the metasurface varies with a change of the light intensity, so that an offset of a phase of the electromagnetic wave signal emitted through the metasurface also varies with the change of the light intensity.

    Abstract: Embodiments are provided for adding a token jump logic to an asynchronous processor with token passing. The token jump logic allows token forward jumps and token backward jumps over a cascade of token processing logics in the processor. An embodiment method includes determining, using a token jump logic coupled to a cascade of token processing logics, whether to administer a token forward jump or a token backward jump of a token signal passing through the token processing logics. The token forward jump and token backward jump allow the token signal to skip one or more token processing logics in the cascade. The method further includes monitoring, for each of the token processing logics, a polarity status of a token sense logic, and inverting the polarity status according to the determination at the token jump logic.
