Patent number: 11971614Abstract: A contact lens comprises a variable focal length lens embedded within the contact lens and a plurality of oxygen channels extending from an oxygen-permeable outer layer of the contact lens to an oxygen-permeable inner layer of the contact lens. The variable focal length lens is embedded within a non-oxygen-permeable core layer of the contact lens. The contact lens comprises a controller configured to change the operating mode of the contact lens by adjusting the focal distance of the variable focal length lens, for instance in response to an input from a user or in response to determining that the user is looking at a nearby object. For instance, the controller can configure the contact lens to operate in a reading mode or in a normal focus mode.Type: GrantFiled: November 18, 2020Date of Patent: April 30, 2024Assignee: Tectus CorporationInventor: Brian Elliot Lemoff

Patent number: 11927836Abstract: Small optics (femtooptics) may be made with optical metasurfaces or diffractive surfaces. Baffles may be formed in the femtooptics with through-glass-via techniques or a variety of etching strategies. Femtooptics may in addition be made using wafer stacking techniques. Variations and combinations of these approaches lead to femtooptics manufacturable in vast quantities by semiconductor wafer processing techniques, also referred to as wafer level optics.Type: GrantFiled: August 9, 2021Date of Patent: March 12, 2024Assignee: Tectus CorporationInventors: Brian Elliot Lemoff, Michael West Wiemer

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: 11740445Abstract: An eye-mounted device includes a contact lens and an embedded imaging system. The front aperture of the imaging system faces away from the user's eye so that the image sensor in the imaging system detects imagery of a user's external environment. The optics for the imaging system has a folded optical path, which is advantageous for fitting the imaging system into the limited space within the contact lens. In one design, the optics for the imaging system is based on a two mirror design, with a concave mirror followed by a convex mirror.Type: GrantFiled: April 8, 2021Date of Patent: August 29, 2023Assignee: Tectus CorporationInventors: Brian Elliot Lemoff, Flint Orin Hamblin, George Michael Mihalakis

Patent number: 11624938Abstract: An unobtrusive augmented reality (AR) system can be used to assist the wearer in every day interactions by projecting information from the contact lens display onto the retina of the wearer's eye. The unobtrusive augmented reality system includes a necklace and a contact lens display that are unobtrusive to the wearer and the wearer's surrounding environment. The necklace of the unobtrusive augmented reality system generates power and data for the contact lens displays. The necklace and contact lens display include conductive coils inductively coupled by a magnetic field. The inductive coupling allows data and power generated by the necklace to be transferred to the contact lens display. A projector in the contact lens display projects images generated from the data onto the retina of the wearers eye.Type: GrantFiled: April 22, 2021Date of Patent: April 11, 2023Assignee: Tectus CorporationInventors: Gregory David Miller, Brian Elliot Lemoff, Kuang-mon Ashley Tuan, Herbert John Kniess, Ion Opris, Michael West Wiemer, Drew Daniel Perkins

Patent number: 11619813Abstract: A small imager mounted on a user's eye (referred to as a femtoimager) is coordinated with an external camera. The femtoimager may be contained in a contact lens, and it may be aligned with the gaze a user's eye. The femtoimager and external camera capture images with overlapping views of the external environment. Images from the two imagers may be compared with one another to estimate the femtoimager's view of the external environment relative to the camera's view of the external environment. This may then be used for different applications.Type: GrantFiled: January 25, 2022Date of Patent: April 4, 2023Assignee: Tectus CorporationInventors: Brian Elliot Lemoff, Ritu Raj Singh, Michael West Wiemer

Patent number: 11604355Abstract: A variety of femtoprojector optical systems are described. Each of them can be made small enough to fit in a contact lens using plastic injection molding, diamond turning, photolithography and etching, or other techniques. Most, but not all, of the systems include a solid cylindrical transparent substrate with a curved primary mirror formed on one end and a secondary mirror formed on the other end. Any of the designs may use light blocking, light-redirecting, absorbing coatings or other types of baffle structures as needed to reduce stray light.Type: GrantFiled: April 8, 2021Date of Patent: March 14, 2023Assignee: Tectus CorporationInventors: Brian Elliot Lemoff, George Michael Mihalakis, Gregory David Miller, Ronald Maynard, Michael West Wiemer

Patent number: 11396985Abstract: LED board interconnect schemes for illuminable assemblies are provided. Multiple LED boards may form a partial perimeter along an illuminable assembly. The multiple LED boards and interconnects must fit within a limited width and height of the illuminable assembly. In some implementations, an interconnect board and spring connectors are used to provide a low-profile electrical interconnection while maintaining co-planarity of the LEDs across the LED boards.Type: GrantFiled: August 27, 2020Date of Patent: July 26, 2022Assignee: Illumina, Inc.Inventors: Brian Elliot Sinofsky, Michael Justin Wright, Lim Peng Huay, Low Hong Yeap, Voon Yeow Seng

Patent number: 11327340Abstract: A variety of femtoprojector optical systems are described. The optical bodies for the systems may be made in batches by wafer-level optics. Each individual system may be made small enough to fit in a contact lens. In some designs, the optical systems include a solid transparent body with a curved primary mirror, a secondary mirror, an entrance window, an exit window, and at least one groove. The grooves function as a light trap that reduces the amount of stray light exiting the body of the optical system. The grooves may also create a snap point which allows removal of individual bodies from the wafer through controlled breakage. The designs may also include various light blocking, light-redirecting, absorbing coatings, or other types structures to reduce stray light.Type: GrantFiled: February 5, 2020Date of Patent: May 10, 2022Assignee: Tectus CorporationInventors: Babak Jamshidi, Flint Orin Hamblin, Brian Elliot Lemoff, Michael West Wiemer

Patent number: 11276188Abstract: An imaging device contained in a contact lens captures images of the external environment, which for convenience will be referred to as real-world images. These real-world images are used to stabilize images produced by a femtoprojector also in the contact lens. For convenience, the images produced by the femtoprojector will be referred to as augmented reality or AR images. The femtoprojector is inward-facing (i.e., facing towards the interior of the eye) and projects the AR images onto the user's retina, creating the appearance of virtual images in the external environment. The imaging device, referred to as a femtoimager for convenience, is outward-facing and captures a sequence of actual real-world images of the external environment. Because the femtoimager and femtoprojector move together, the real-world images captured by the femtoimager reflect the motion of the virtual AR images from the femtoprojector relative to the external environment.Type: GrantFiled: May 1, 2020Date of Patent: March 15, 2022Assignee: Tectus CorporationInventors: Abhishek Deepak Bhat, Ramin Mirjalili, Brian Elliot Lemoff, Joseph Czompo, Michael West Wiemer
