Abstract: A piezoelectric sensor is provided. The piezoelectric sensor comprises a first base, a first conductive layer adjacent to the first base, a second base, a second conductive layer adjacent to the second base; and a first structure between the first conductive layer and the second conductive layer. The first structure comprises a first layer with a first carbon-based material and a plurality of second structures with piezoelectricity. Each of the plurality of second structures comprises a second layer with a second carbon-based material and a third layer adjacent to the second layer. The third layer comprises a material of two-dimensional crystals of unconventional stoichiometries such as Na2Cl crystals.

Abstract: A continuously variable transmission with both equal-difference output and equal-ratio output includes an input mechanism, a hydraulic transmission mechanism, a planetary-gear-set convergence mechanism, an equal-difference output mechanism, an equal-ratio output mechanism, a clutch assembly, and a brake. The clutch assembly connects an output end of the input mechanism to an input end of the hydraulic transmission mechanism and the planetary-gear-set convergence mechanism and connects an output end of the hydraulic transmission mechanism to the planetary-gear-set convergence mechanism. The clutch assembly connects the planetary-gear-set convergence mechanism to the equal-difference output mechanism and the equal-ratio output mechanism. The clutch assembly connects the equal-ratio output mechanism to the equal-difference output mechanism.

The method includes obtaining a first image corresponding to a to-be-processed image, obtaining a second image corresponding to the to-be-processed image, wherein the first image and the second image are obtained in response to an image degradation processing being performed with respect to the to-be-processed image, and an image quality of the first image and an image quality of the second image are different. The method further includes obtaining image structural information corresponding to the to-be-processed image, and performing an image fusion processing with respect to the first image and the second image to image fusion based at least in part on the image structural information corresponding to the to-be-processed image, wherein a target image is obtained based at least in part on the image fusion processing, and the target image corresponds to the to-be-processed image.

Abstract: In a push-to-talk communication system, a domain name server transfers a registration server role, call server role, and media server role. A first server receives the registration server role and responsively registers push-to-talk users and maintains a first time of day. A second server receives the call server role and responsively establishes push-to-talk calls and maintains a second time of day. A third server receives the media server role and responsively transfers push-to-talk media and maintains a third time of day. A management system receives and processes data from the servers to verify that their time of day is synchronized and to verify that the servers are performing their assigned push-to-talk roles.

Abstract: The thermal insulating material of the present invention allows for the use of microballoons as an insulating material for the exterior surface of pipes. In the present invention, microballoons are mixed with a water based epoxy while in its liquid state. To absorb the water from the water based epoxy, cement is added to the mixture. The mixture of water based epoxy, microballoons and cement is then extruded or thrown onto the exterior surface of pipes.
