A fluidic-device valve may include a valve guide having a guide wall surrounding a central axis. The guide wall may include a first guide section, a second guide section, and an interior surface that defines a valve cavity extending longitudinally along the central axis from the first guide section to the second guide section. The valve may also include a valve member having a ferromagnetic material disposed within the valve cavity, and the valve member may extend longitudinally along the central axis. The valve member may also have a first plug section and a second plug section and may define a fluid conduit between the first plug section and the second plug section. Various other methods, systems, and computer-readable media are also disclosed.

Electromagnetically actuated fluidic-device valve apparatuses, systems, and methods

An optical sensor measures displacement of a haptic plate that provides haptic sensation to a user. The optical sensor comprises a light source, a plurality of optical detectors, and a controller. The light source is configured to illuminate a surface of the haptic plate in which a haptic wave propagates causing displacement of portions of the haptic plate in one or more directions. The plurality of optical detectors is configured to detect light reflected from the surface of the haptic plate. At least two optical detectors of the plurality of optical detectors are positioned relative to the light source such that an amount of light received at each of the optical detectors is based at least in part on a direction of displacement of the haptic plate. The controller is configured to monitor the haptic wave using the detected light from the plurality of optical detectors.

Optical sensor for measuring displacement of a haptic plate

A haptic device provides haptic sensation to a user. The haptic device comprises a haptic plate and a plurality of actuators. The haptic plate includes a center portion and an outer portion that circumscribes the center portion. The plurality of actuators is coupled to the outer portion of the haptic plate. Of the plurality of actuators, one or more actuators are configured to generate, in accordance with haptic instructions, a haptic wave that converges to a specific waveform at a specific region of the center portion of the haptic plate. The shape of the specific waveform and the location of the specific region on the center portion of the haptic plate are based in part on the haptic instructions.
