摘要： In some examples, techniques are provided for quick haptic feedback, without the use of a controller, which is local to individual, non-actuating keys, such as keys of a thin keyboard or keypad. The haptic feedback may be in the form of a simulated “key-click” feedback for an individual key that is pressed by a user such that the finger used to press the key feels the tactile sensation. The haptic feedback mimics the tactile sensation of a mechanical key (e.g., buckling spring, pop-dome key switch) to give a user the perception that they have actuated a mechanically movable key.

摘要： A resonant member of a MEMS resonator oscillates in a mechanical resonance mode that produces non-uniform regional stresses such that a first level of mechanical stress in a first region of the resonant member is higher than a second level of mechanical stress in a second region of the resonant member. A plurality of openings within a surface of the resonant member are disposed more densely within the first region than the second region and at least partly filled with a compensating material that reduces temperature dependence of the resonant frequency corresponding to the mechanical resonance mode.

摘要： A vibrator includes: a base portion; a vibrating arm including an arm portion which extends from the base portion, and a weight portion which is located on a tip end side of the arm portion and which has a first main surface and a second main surface that are in a front-back relationship; and a weight film disposed at the first main surface of the weight portion. The first main surface includes a first planar surface, a second planar surface which is located closer to the second main surface than is the first planar surface and which is parallel to the first planar surface, and an inclined surface which couples the first planar surface and the second planar surface and which forms an angle of 100° or less with the first planar surface. A method for manufacturing a vibrator includes: a preparation step of preparing the above-described vibrator; and a removing step of removing a part of the weight film by emitting an energy ray to the weight film from a normal direction of the first planar surface.

摘要： A method of manufacture for an acoustic resonator device. The method includes forming a nucleation layer characterized by nucleation growth parameters overlying a substrate and forming a strained piezoelectric layer overlying the nucleation layer. The strained piezoelectric layer is characterized by a strain condition and piezoelectric layer parameters. The process of forming the strained piezoelectric layer can include an epitaxial growth process configured by nucleation growth parameters and piezoelectric layer parameters to modulate the strain condition in the strained piezoelectric layer. By modulating the strain condition, the piezoelectric properties of the resulting piezoelectric layer can be adjusted and improved for specific applications.

摘要： In some embodiments, in response to the user selecting a first node in the tree to be pinned, the system displays a first detail panel for the first node, wherein the first detail panel displays state information for the first node, wherein the state information is frozen at the time of pinning. Moreover, in response to the user selecting a second node in the tree to be pinned, the system displays a second detail panel for the second node, wherein the second detail panel displays state information for the second node, wherein the state information is frozen at the time of pinning. Note that the first detail panel is displayed concurrently with the second detail panel to facilitate comparing state information between the first and second nodes.

摘要： An application displaying primary content, such as a webpage, may include unused space. The unused space may exist within the application displaying the primary content (e.g., within the browser window) or on other portions of the display (e.g., outside of the browser window). The unused space is identified and leveraged to display secondary content on the client display along with the primary content. The secondary content may be adaptable to conform to different sizes and/or configurations of the unused space. The secondary content may be updated as the user interacts with elements on the client display.

摘要： A lithium niobate semiconductor structure includes: a first lithium niobate material layer, a second lithium niobate material layer and a third lithium niobate material layer. A polarization direction of a ferroelectric domain of the first lithium niobate material layer is a first direction. The second lithium niobate material layer is spaced apart from the first lithium niobate material layer, and a polarization direction of a ferroelectric domain of the second lithium niobate material layer is the first direction. The third lithium niobate material layer is sandwiched between the first lithium niobate material layer and the second lithium niobate material layer, and a polarization direction of a ferroelectric domain of the third lithium niobate material layer is a second direction; the first direction is opposite to the second direction.
