Patent number: 12099214Abstract: A near-eye display includes a light-guide optical element (LOE) (10) having first and second major external surfaces (11A, 11B) that are planar and mutually parallel. An image projector (2) introduces into the LOE illumination corresponding to an image so that the illumination propagates within said LOE by internal reflection at the major external surfaces. A coupling-out arrangement couples the illumination out of the LOE towards the eye of the observer. The coupling-out arrangement may be a set of mutually-parallel, partially-reflective surfaces (12A) deployed at an oblique angle within the LOE. Various arrangements for suppressing reflections of ambient light sources include obstructing baffles oriented so as to avoid reduction of peripheral field of view, various non-reflective coatings and various deployments of polarization filters.Type: GrantFiled: August 26, 2019Date of Patent: September 24, 2024Assignee: LUMUS LTD.Inventors: Eitan Ronen, Yochay Danziger, Jonathan Gelberg, Tsion Eisenfeld, Amir Shapira

Patent number: 12099258Abstract: Techniques are described for applying an edge sealant to the edge of a multi-layer optical device. In particular, embodiments provide an apparatus that performs a precision measurement of the perimeter of an eyepiece, applying the edge sealant (e.g., polymer) based on the precision-measured perimeter, and subsequently cures the edge sealant, using ultraviolet (UV) light that is directed at the edge sealant. The curing process may be performed within a short time following the application of the edge sealant, to ensure that any wicking of the edge sealant between the layers of the eyepiece is controlled to be no greater than a particular depth tolerance. In some examples, the edge sealant is applied to the optical device prevent, or at least reduce, the leakage of light from the optical device, and also to ensure and maintain the structure of the multi-layer optical device.Type: GrantFiled: November 10, 2022Date of Patent: September 24, 2024Assignee: Magic Leap, Inc.Inventors: Wendong Xing, Neal Paul Ricks, Thomas Mercier, William Hudson Welch

Patent number: 12099261Abstract: A system includes an electronic contact lens that obtains sensor measurements from integrated motion sensors or other types of sensors and a processing module that estimates a mental state of an individual based on the sensor measurements. The processing module identifies patterns of eye movements and analyzes how these patterns change over time. Based on anatomical relationships between eye movement and mental state, the processing module estimates characteristics of the individual such as fatigue, intoxication, injury, or a medical condition that have known effects on eye movement patterns. The electronic contact lens system generates an output indicative of the estimated mental state to alert the individual to the detected condition or to initiate an automated action.Type: GrantFiled: August 10, 2021Date of Patent: September 24, 2024Assignee: TECTUS CORPORATIONInventors: Ramin Mirjalili, Abhishek Deepak Bhat
