Abstract: Systems, devices, and methods for preventing eyebox degradation in wearable heads-up displays (“WHUDs”) are described. A WHUD may provide an eyebox defined by multiple spatially-separated exit pupils, where the size of the eyebox is influenced by the spacing between the exit pupils. A larger eyebox is achieved with larger spacing between the exit pupils but a larger spacing between exit pupils is susceptible to the formation of gaps or blind spots in the eyebox (eyebox degradation) if bright environmental light causes the user's pupil to constrict to a size that is smaller than the spacing between the exit pupils. A material of variable chromism is included in the user's field of view to reduce the perceived brightness of environmental light and thereby prevent the user's pupil from constricting to a size smaller than the spacing between the exit pupils.

Each pin actuation unit can also include an angular position sensing system for monitoring, for example magnetically, a passage of the shaft through a reference angular position, and deriving information about a current angular position of the shaft.

Abstract: Systems, devices, and methods for eyebox expansion by exit pupil replication in wearable heads-up displays (“WHUDs”) are described. A WHUD includes a scanning laser projector (“SLP”), a holographic combiner, and an optical splitter positioned in the optical path therebetween. The optical splitter receives light signals generated by the SLP and separates the light signals into N sub-ranges based on the point of incidence of each light signal at the optical splitter. The optical splitter redirects the light signals corresponding to respective ones of the N sub-ranges towards the holographic combiner effectively from respective ones of N spatially-separated virtual positions for the SLP. The holographic combiner converges the light signals to respective ones of N spatially-separated exit pupils at the eye of the user. In this way, multiple instances of the exit pupil are distributed over the area of the eye and the eyebox of the WHUD is expanded.

Abstract: A rejuvenation and massage device is provided for treating mucosa tissue, such as vaginal tissue, affected by Vaginal Relaxation Syndrome (VRS) or other conditions, through vibration, thermal loading, and light emittance for a duration of time. In one embodiment, the device is an insertable device that includes Low-Level Laser Light (LLLT) therapy to treat the vaginal tissue. The light emittance by one or more light emitters is in a range sufficient to provide therapeutic effects through light radiation. To enhance the therapeutic effects of light radiation provided by the device, the device is configured to provide increased energy density into target tissue of vaginal muscles though a light configuration component (e.g., a focusing component, such as a concave lens assembly, a convex assembly, a pre-lensed light emitter or other focusing optical mechanism) associated with the light emitter that concentrates the light emitted from the light emitter.

Abstract: A light emitting module and massage device provide vaginal rejuvenation. The device exposes collagen in the vaginal area or mucosa to temperatures elevated over normal body temperature to cause the collagen to reversibly or irreversibly denature while simultaneously applying vibration. Once thermally-induced collagen denaturation has occurred, both neoelastogenesis and neocollagenesis may occur and may be initiated with fibroblast proliferation, which may be promoted with vibration. Neofibrogenesis also occurs due to the fibroblastic activity, responsible for secretion of new collagen matrix to effect tissue repair. Thus, the device exploits thermally-induced collagen denaturation and repair along with simultaneous vibration to improve tissue tone, connective tissue tension and bulk tissue regeneration.

Abstract: Systems, devices, and methods for engineering the eyebox of a display using multiple heterogeneous exit pupils are described. The eyebox of a display includes at least two heterogeneous exit pupils that are different from one another in terms of size and/or shape. Heterogeneous exit pupils may overlap, one may encompass another, or they may be completely spatially-separated from one another. Such configurations enable specific eyebox and/or visual display configurations that can be advantageous in certain applications. An example in which a scanning laser-based wearable heads-up virtual retina display implements a holographic combiner that is engineered to provide multiple heterogeneous exit pupils is described.

Abstract: Systems, devices, and methods for eyebox expansion by exit pupil replication in wearable heads-up displays (“WHUDs”) are described. A WHUD includes a scanning laser projector (“SLP”), a holographic combiner, and an exit pupil selector positioned in the optical path therebetween. The exit pupil selector is controllably switchable into and between N different configurations. In each of the N configurations, the exit pupil selector receives a light signal from the SLP and redirects the light signal towards the holographic combiner effectively from a respective one of N virtual positions for the SLP. The holographic combiner converges the light signal to a particular one of N exit pupils at the eye of the user based on the particular virtual position from which the light signal is made to effectively originate. In this way, multiple instances of the exit pupil are distributed over the eye and the eyebox of the WHUD is expanded.

Abstract: Systems, devices, and methods for spatial multiplexing in holographic optical elements (“HOEs”) are described. A spatially-multiplexed HOE includes multiple spatially-separated holographic regions and each spatially-separated region applies a respective optical function to light that is incident thereon. An exemplary application as a spatially-multiplexed holographic combiner (“SMHC”) in a scanning laser-based wearable heads-up display (“WHUD”) is described. In this exemplary application, a scanning laser projector directs multiple light signals over the area of the SMHC and the SMHC converges the light signals towards multiple spatially-separated exit pupils at or proximate the eye of the user. The particular exit pupil at the eye of the user towards which any particular light signal is converged by the SMHC depends on the particular region of the SMHC upon which the light signal is incident.
