Abstract: A wireless force sensor includes a flexible structure supported opposing a rigid structure with a gap between the flexible structure and the rigid structure. Contact traces on opposing surfaces of the flexible structure and the rigid structure form transmission lines. The contract traces are aligned to contact when a force is applied the flexible structure to cause contact between the traces on the opposing surfaces. Radio-frequency switches modulate a reflected signal from the transmission lines. An antenna receives an interrogation signal transmits the reflected signal.

Abstract: A method, a system, and a computer program product for enabling reliable millimeter links in wireless communications systems. One or more beams associated with a plurality of communication paths is trained to determine one or more angles corresponding to the beams at which the beams are received by at least one of a first communication device and a second communication device. Using the determined one or more angles, at least one communication path in the plurality of communication paths is selected for transmission of one or more data packets between the first and second communication devices. Using the selected communication path, one or more data packets are transmitted.
