Abstract: A radio frequency filter includes at least a first sub-filter and a second sub-filter connected in parallel between a first port and a second port. Each of the sub-filters has a piezoelectric plate having front and back surfaces, the back surface attached to a substrate, and portions of the piezoelectric plate forming diaphragms spanning respective cavities in the substrate. A conductor pattern is formed on the front surface of the plate, the conductor pattern includes interdigital transducers (IDTs) of a respective plurality of resonators, with interleaved fingers of each IDT disposed on a respective diaphragm of the plurality of diaphragms. A thickness of the portions of the piezoelectric plate of the first sub-filter is different from a thickness of the portions of the piezoelectric plate of the second sub-filter.

Abstract: A container includes a base; side walls extending upwards from an upper face of the base; and at least one support plate which is spaced apart from a lower face of the base and is connected to the lower face of the base by ribs extending transversely to the base and transversely to the at least one support plate. At least two laterally protruding projections are formed at least on an edge portion of the support plate extending along one of the side walls. At least two support recesses for receiving at least two projections of a support plate of an identical container stacked thereon are formed in the upper edge portion of the at least one side wall.

Abstract: A multi-component snap assembly is disclosed herein in which a snap flange has a snap nose with a contact face including a relief. The relief is configured to prevent undesirably high stress in the snap flange during assembly with another component that includes a retention pocket. A method of attaching or connecting two components with each other using a snap flange with a relief is also disclosed herein.

Abstract: A strain gauge assembly is provided comprising a base including a core and at least one gauge support. The core is longer than the at least one gauge support and the at least one gauge support is fixed to an outer surface of the core. The at least one gauge support has a greater stiffness than the core. The strain gauge assembly also includes at least one strain gauge fixed on an outer surface of the at least one gauge support.
