Patent number: 11874961Abstract: An augmented reality device manages display of an interactive icon in a manner that enables selection by a simple and intuitive gesture. The interactive icon may initially be displayed at a predefined target position outside the fovea where it is visible in the near peripheral vision without being distracting to the user. The augmented reality device may control the icon to behave like a stationary object with respect to changes in orientation until selection or repositioning criteria are met. Upon detection repositioning criteria, the augmented reality device may reposition the icon to the target position. Selection of the icon may control functions such as alerting the user to an available notification, opening or closing a menu, or performing other actions associated with operation of the augmented reality device.Type: GrantFiled: May 9, 2022Date of Patent: January 16, 2024Assignee: TECTUS CORPORATIONInventors: Ben Rafael Kimel Green, Dominic Philip Haine

Patent number: 11741863Abstract: Advanced display devices are integrated into glasses so that they look and feel more like normal glasses. They are based on pupil replication using multiple, small projectors. A number of projectors are embedded in the eyeglasses, for example embedded in the rim of the eyeglasses or in a periphery of the lens. The projectors generate (partial) images based on a common image to be displayed to the user. These images are optically coupled through the lens, for example using waveguide coupling, to different display windows in the lens. The display windows couple the images out of the lens and towards the user's eye.Type: GrantFiled: January 13, 2022Date of Patent: August 29, 2023Assignee: Tectus CorporationInventors: Paul Scott Martin, Brian Elliot Lemoff

Patent number: 11686953Abstract: A contact lens having a cap, core, and base forming three layers to allow for the contact lens to be thick enough to accommodate a payload, while ensuring sufficient oxygenation of the wearer's eye. The cap and base are each a thin layer of gas-permeable material, each shaped to form an air gap between them and the core. The two air gaps are connected by air passages that traverse the core. Oxygen from an outside environment passes through the gas-permeable cap to reach the outer air gap, through the air passages to the inner air gap, and through the gas-permeable base to reach the cornea of the wearer's eye. The cap may be annular in form, having a center hole such that the cap does not extend over the central zone of the core, reducing a thickness of the contact lens.Type: GrantFiled: December 6, 2021Date of Patent: June 27, 2023Assignee: Tectus CorporationInventors: Benjamin Lyle Hackett, Eric Johnson, Michael West Wiemer, Donald Arthur Ice

Patent number: 11681164Abstract: An electronic contact lens contains electrical components connected by an electrical interconnect. The electrical interconnect has a flat body, with electrical conductors running length-wise along the body. The flat body is oriented perpendicular rather than parallel to the inner and outer surfaces of the contact lens to reduce a visible profile of the interconnect, reducing the amount of light blocked from entering the eye. The body has a curvature shaped to conform to the curvature of the contact lens. As examples, the interconnect may be connected with an electrical component using a tab perpendicular to the flat body of the interconnect, or by forming an edge connection with electrical contacts of the component located along an edge of the component, or through one or more exposed vias formed on the component.Type: GrantFiled: July 27, 2018Date of Patent: June 20, 2023Assignee: Tectus CorporationInventors: Babak Jamshidi, Ben H.

Patent number: 11662807Abstract: The present disclosure relates generally to eye-tracking systems and methods that provide a user the ability to efficiently activate the system and select and dismiss virtual objects within an augmented reality (“AR”) and/or virtual reality (“VR”) environment. A user may activate the user interface by glancing beyond an activation threshold positioned close enough to the edge of the field of view to reliably infer an intent to activate the virtual controls. Subsequently, the user interacts with virtual tools, first virtual “peek” windows and secondary virtual windows to obtain content or virtual control across a variety of granular levels. Subsequently, the user may glance away at virtual content or to other predefined areas within their eye's range of motion to dismiss the tool and/or deactivate the system.Type: GrantFiled: July 27, 2020Date of Patent: May 30, 2023Assignee: Tectus CorporationInventors: Dominic Philip Haine, Scott Herz

Patent number: 11626551Abstract: Additional “auxiliary” bumps are used to stabilize alignment and reduce slippage of dense arrays of interconnect bumps on opposing die during a bonding process. One example of auxiliary bumps are interdigitated bumps. Interdigitated bumps are more self-aligning and laterally stable because bumps do not meet head-to-head. Rather, the head of a bump on one die falls into the space between bumps on the other die. Another example of auxiliary bumps are nail bumps. In nail bumps, one bump is harder (the nail) and “drives” into the opposing softer bump during bonding. This constrains the lateral movement of the two bumps relative to each other and reduces lateral slippage. In some embodiments, the auxiliary bumps and interconnect bumps are formed in the same process, and also bonded in the same process.Type: GrantFiled: January 29, 2021Date of Patent: April 11, 2023Assignee: Tectus CorporationInventors: Nachiket Raghunath Raravikar, Arnold Daguio, Kwong-Hin Henry Choy, Tigran Nshanian, Paul Scott Martin
