Abstract: An automatically adjustable radiofrequency link system includes a radiofrequency transmitter configured to transmit a signal at a frequency of transmission within an extremely high frequency (EHF) band. The system further includes a receiving device configured to receive the transmitted signal and provide feedback to a processing circuit communicatively coupled to the transmitter and the receiving device, wherein the feedback is related to the received signal. The processing circuit is configured to determine required signal properties based on the feedback and determine signal loss properties including an effect of atmospheric absorption, as a function of frequency; determine a modification to the transmitted signal using the signal loss properties and the required signal properties; and adjust the frequency of transmission to obtain a desired transmission signal using the modification.

Abstract: A vehicle collision detection system may be configured to coordinate with collision detection systems of other vehicles. The coordination may comprise sharing sensor data with other vehicles, receiving sensor information from other vehicles, using sensor information to generate a collision detection model, sharing the collision detection model with other vehicles, receiving a collision detection model from other vehicles, and the like. In some embodiments, vehicles may coordinate sensor operation to form a bistatic and/or multistatic sensor configuration, in which a detection signal generated at a first land vehicle is detected at a sensing system at a second land vehicle.

Abstract: A method of pumping an optical resonator includes directing light generated by a pumping light at the optical resonator, exciting a propagating surface state of the optical resonator at an interface of the optical resonator, and changing a propagating frequency of the light proximate the interface, where the changed frequency corresponds to a propagation frequency of the surface state. The optical resonator includes a photonic crystal and a material, where the interface is formed between the photonic crystal and the material.
