Abstract: An optical system for a head-worn computer includes an upper optical module adapted to convert illumination into image light by illuminating a reflective display through a field lens, wherein the image light is transmitted back through the field lens, then through a partially reflective partially transmissive surface and into a lower optic module adapted to present the image light to an eye of a user wearing the head-worn computer and the upper optical module being positioned within a housing for the head-worn computer and having a height of less than 24 mm, as measured from the reflective display to the bottom edge of the rotationally curved partial mirror.

Abstract: Aspects of the present invention relate to a head-worn computer, comprising a removable and replaceable adjustable nose bridge assembly, wherein the adjustable nose bridge assembly has at least three user adjustable features to adapt the adjustable nose bridge assembly to the user's nose, wherein a first adjustment of the at least three user adjustable features is adapted to move the adjustable nose bridge up and down relative to a lens of the head-worn computer, wherein a second adjustment of the at least three user adjustable features is adapted to rotate a nose pad of the adjustable nose bridge about an axis substantially perpendicular to a top frame of the head-worn computer, and wherein a third adjustment of the at least three user adjustable features is adapted to flare the nose pad to the side of the axis.

Abstract: Aspects of the present invention relate to methods and systems for the see-through computer display systems with integrated IR eye imaging technologies.

Abstract: Aspects of the present invention relate to methods and systems for providing a high transmission see-through view of the environment while trapping escaping light from the display system. In embodiments, a camera system is also provided that is aligned with the display system to provide images of the environment in a viewing direction of the user.

Abstract: Aspects of the present disclosure relate a head-worn computer with a see-through display wherein computer content is presented to a user wearing the head-worn computer and through which the user sees a surrounding environment, wherein the see-through display generates image light comprised of narrow bandwidths of red, green and blue light and wherein the see-through display further includes a tristimulus notch mirror positioned to reflect the image light towards the user's eye, and wherein the tristimulus notch mirror reflects less than a full width half max of the red image light.

Abstract: Aspects of the present invention relate to methods and systems for measuring and managing the brightness of digital content in a field of view of a head-worn computer.

Abstract: Methods and systems for presenting digital content on a see-through display are disclosed. In some embodiments, the digital content is presented based on a display attribute associated with personal information related to a user of a wearable head device comprising the see-through display. In some embodiments, the digital content is associated with a geo-spatial location of a physical structure, and presenting the digital content on the see-through display comprises indicating a spatial relationship between the digital content and the physical structure.

Abstract: Disclosure herein concerns a method that includes illuminating a user's eye with an illumination source in a head-worn display, capturing an image of the user's eye with an eye camera in the head-worn display, wherein the image includes an eye glint produced by light from the illumination source that is reflected from a surface of the user's eye, determining a size of an eye glint in the captured image, and identifying a change in focus distance for the user's eye in correspondence with a change in the size of the eye glint.

Abstract: Head-worn computers include a front frame mechanically adapted to secure a see-through computer display and an arm, secured to the front frame, mechanically adapted to secure the front frame to a head of a user. The arm includes an internal speaker system, enclosed by the arm, wherein the internal speaker system comprises a speaker having a first side and an opposing second side and a first cavity positioned along the first side of the speaker, the arm further comprising a vent positioned to vent the first cavity and a second cavity positioned along the second side of the speaker.

Abstract: Aspects of the present invention relate to methods and devices for receiving and presenting content. In an example method, content is received, the content to be delivered to a plurality of recipients. Each recipient of the plurality of recipients has a preference for a respective first physical location at which the content is to be presented on a display of a wearable head device associated with the recipient. A sender of the content has a preference for a second physical location at which the content is to be presented to the respective recipient of the plurality of recipients. A respective final physical location for the presentation of the content for the respective recipient of the plurality of recipients is identified. The respective final physical location is based on the respective recipient's preference and the sender's preference. It is determined whether the respective recipient is proximate to a zone associated with the respective final physical location.
