摘要： A device includes multiple payloads that are adjusted by actuators. The payloads may be optical elements such as lens assemblies. The actuators may be disposed within edge gaps of the payloads in order to reduce the footprint of the structure. One actuator may be configured to adjust more than one payload to reduce the number of actuators.

摘要： A device includes a pair of electrodes and a dynamic material disposed between the pair of electrodes, the dynamic material including a crystalline microstructure configured to change between at least two states in response to a change in an electric field between the two electrodes. A material includes tetragonal lead magnesium niobate-lead titanate (PMN-PT) and at least one lanthanide series element. A method includes doping a lead magnesium niobate-lead titanate material with at least one lanthanide series element, and processing the PMN-PT material to form tetragonal PMN-PT. A further method includes forming a low refractive index nanostructured grating over a carrier substrate, forming a high refractive index layer over the low refractive index grating to produce a nanostructured coupling element, forming an adhesive layer over the nanostructured coupling element, and affixing the nanostructured coupling element to a high index waveguide.

摘要： Disclosed devices may include a membrane having a membrane curvature, a substrate, an enclosure (defined at least in part by the membrane and the substrate) enclosing a fluid, a peripheral structure configured to adjust the membrane curvature, and a sensor configured to provide a sensor signal that is a function of the membrane curvature. The device may also include a controller configured to control the membrane curvature using a control signal. For example, the control signal may be provided to at least one actuator. The controller may receive a sensor signal from the sensor and modify the control signal based on the sensor signal. Examples also include associated methods and systems.

摘要： An adjustment image of a projected image is captured by a disparity image sensor. A first defocus factor in generated response to comparing the adjustment image with a reference image driven onto a display projector assembly the generated the projected image. A second defocus factor is generated in response to an alignment of a first intensity profile of the adjustment image and a second intensity profile of the adjustment image. A focusing lens of the display projector assembly is adjusted in response to at least one of the first defocus factor and the second defocus factor.

摘要： An apparatus, system, and method for micro-electro-mechanical system (MEMS) micromirror including a plurality of stiffening structures is described. The MEMS micromirror includes a mirror surface to reflect light, a support platform coupled along a mirror surface, and a plurality of stiffening structures formed from or coupled to the support platform. In some examples, a dimensionality or density of the stiffening structures scale across an area of the support platform in a manner to assist in keeping the mirror surface flat under torsional force.

摘要： Disclosed devices may include a membrane, a first electrode supported by the membrane, a second electrode, a capacitance sensor configured to determine a capacitance measurement between the first electrode and the second electrode, and a controller configured to control an electrical potential applied between the electrode and the second electrode. The controller may be configured to modify the electrical potential based on the capacitance measurement. Example devices may include one or more flexible membranes that may, at least in part, define an enclosure that is at least partially filled with a dielectric fluid. Examples also include associated methods and systems.

摘要： An actuator assembly includes a primary electrode, a secondary electrode overlapping at least a portion of the primary electrode, and an electroactive polymer layer disposed between the primary electrode and the secondary electrode, where the electroactive polymer layer includes a non-vertical (e.g., sloped) sidewall with respect to a major surface of at least one of the electrodes. The electroactive polymer layer may be characterized by a non-axisymmetric shape with respect to an axis that is oriented orthogonal to an electrode major surface.

摘要： An actuator may be integrated into an optical element such as a liquid lens and configured to create spherical curvature as well as a variable cylinder radius and axis in a surface of the optical element. An example actuator may include a stack of electromechanical layers, and electrodes configured to apply an electric field independently across each of the electromechanical layers. Within the stack, an orientation of neighboring electromechanical layers may differ, e.g., stepwise, by at least approximately 10°.
