摘要： An elastic wave filter device includes a piezoelectric film, a high acoustic velocity support substrate in which an acoustic velocity of a propagating bulk wave is larger than an acoustic velocity of a main mode elastic wave propagating in the piezoelectric film, and IDT electrodes in contact with the piezoelectric film. A serial arm resonator and a parallel arm resonator are defined by the IDT electrodes such that, a direction in which tips of first and second electrode fingers are connected defines a tilt angle with respect to a propagation direction of elastic waves excited by the IDT electrodes. A tilt angle of the serial arm resonator is different from a tilt angle of the parallel arm resonator.

摘要： Introduced here are methods and systems to create a relief on an electronic display. In one embodiment, the relief is created by micro-electromechanical systems (MEMS) placed above a cover layer of the electronic display. Each MEMS when activated can protrude or depress, thus creating the relief on the electronic display. In another embodiment, the relief is created by a plurality of resistors placed beneath the cover layer. The cover layer is made out of an elastically deformable material that, when heated, expands, thus creating a protrusion on the electronic display. Each resistor when activated heats a section of the cover layer, causing the cover layer to protrude.
