Abstract: An acoustic wave element includes: a substrate; a bonding structure on the substrate; a support layer on the bonding structure; a first electrode including a lower surface on the support layer; a cavity positioned between the support layer and the first electrode and exposing a lower surface of the first electrode; a piezoelectric layer on the first electrode; and a second electrode on the piezoelectric layer, wherein at least one of the first electrode and the second electrode includes a first layer and a second layer that the first layer has a first acoustic impedance and a first electrical impedance, the second layer has a second acoustic impedance and a second electrical impedance, wherein the first acoustic impedance is higher than the second acoustic impedance, and the second electrical impedance is lower than the first electrical impedance.

Abstract: A system for generating structured queries and carrying out searches using the structured queries may result in high quality queries and may adequately simulate natural language for suggested search queries. In embodiments, attributes and matching product/services may be extracted from various data sources. Structured queries that include the attributes, products/services, and/or additional terms may be combined to form a structured query. In various embodiments, each structured query may be structured according to a pre-defined pattern that is selected based on the type of relevant product and/or service.

Abstract: A network system control method includes intercepting a flow modification message sent by a controller from a network protocol path between a switch and the controller so as to obtain a new flow entry; accessing a flow table of the switch so as to obtain a plurality of flow entries; inserting at least one redundant flow entry according to the new flow entry and the plurality of flow entries; performing an aggregation operation to the new flow entry, the plurality of flow entries and the at least one redundant flow entry so as to generate a set of aggregated flow entries; and updating the flow table using the set of aggregated flow entries.

Abstract: A fire-proof wood board with tenon engagement comprises: a surface plate made by hard, fire-proof, water-proof, and wear-endurance wood textured plate; a fire-proof liner plate below the surface plate; and a substrate below the fire-proof liner plate and each end of the substrate being formed with a notch and a tenon; the tenon having a configuration corresponding to the notch so that the tenon and notch being engaged to connect two adjacent substrates together. The fire-proof liner plate is made of material selected from one of calcium silicic acid plate, magnesium oxide plates, cement plates, and gypsum plates. The substrate is selective from one of wood splint plates, wood compressing plates, decorative higher pressure plates. Furthermore, the fire-proof wood board is used as one of floorboards, wallboards and ceiling boards.
