Abstract: A control method includes sending, by a controller, a created context-aware model to a context-aware engine. The context-aware model is used to define a preset control performed when target data meets a trigger condition and to instruct the context-aware engine to send indication information to the controller when the context-aware engine determines that the target data meets the trigger condition. The preset control is used to implement a context-aware function. The indication information is used to indicate that the target data meets the trigger condition. The method also includes receiving, by the controller, the indication information. The method further includes performing, by the controller, the preset control based on the indication information.

Abstract: A surface acoustic wave filter includes a support substrate with a first acoustic velocity layer disposed above. The first acoustic velocity layer is silicon dioxide with a piezoelectric layer above. Euler angles of a cut of the piezoelectric layer are (−5° to 5°, 81° to 83°, 85° to 95°), and an interdigital electrode is disposed above the piezoelectric layer. A second acoustic velocity layer included between the first acoustic velocity layer and the support substrate; and a material of the second acoustic velocity layer is aluminum nitride or silicon nitride, where a longitudinal wave acoustic velocity in the first acoustic velocity layer is lower than a longitudinal wave acoustic velocity in the piezoelectric layer, and a longitudinal wave acoustic velocity in the second acoustic velocity layer is higher than the longitudinal wave acoustic velocity in the piezoelectric layer.
