  • Patent number: 11940641
    Abstract: A light pipe includes at least two optical structures having different refractive indices. An interface between the two optical structures is oblique to a longitudinal axis of the light pipe such that an output ray from an output surface at a distal end of the light pipe is non-parallel to an input ray that is parallel to the longitudinal axis at an input surface at a proximal end of the light pipe. Light refracts inside the light pipe between the (at least) two optical structures altering the direction of an optical path of the light through the light pipe, thereby allowing higher degrees of freedom for the selection of the angle of deviation (folding angle) of the light pipe. By optimizing various parameters of the light pipe, a desired output optical axis angle (i.e., folding angle) can be achieved that suits the desired optical engine envelope.

  • Patent number: 11907426
    Abstract: An electronic device has a housing that forms an exterior surface of the electronic device. An array of actuators is coupled to the housing and is operable to move the housing in order to produce sound waves and/or haptic output via the exterior surface. In this way, less space is consumed by acoustic and haptic devices as compared to similar conventional devices, thereby allowing for thinner electronic devices and/or room for other components within the housing. The actuators may be operable to move different regions of the housing to produce sound waves and/or haptic output within different frequency ranges.
