Publication number: 20210223576Abstract: 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: ApplicationFiled: April 8, 2021Publication date: July 22, 2021Inventors: Brian Elliot Lemoff, Flint Orin Hamblin, George Michael Mihalakis

Publication number: 20210223555Abstract: 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: ApplicationFiled: April 8, 2021Publication date: July 22, 2021Inventors: Brian Elliot Lemoff, George Michael Mihalakis, Gregory David Miller, Ronald Maynard, Michael West Wiemer

Patent number: 11029535Abstract: 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 8, 2020Date of Patent: June 8, 2021Assignee: Tectus CorporationInventors: Gregory David Miller, Brian Elliot Lemoff, Kuang-mon Ashley Tuan, Herbert John Kniess, Ion Opris, Michael West Wiemer, Drew Daniel Perkins

Publication number: 20210071830Abstract: 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: ApplicationFiled: August 27, 2020Publication date: March 11, 2021Inventors: Brian Elliot Sinofsky, Michael Justin Wright, Lim Peng Huay, Low Hong Yeap, Voon Yeow Seng

Publication number: 20210072561Abstract: 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: ApplicationFiled: November 18, 2020Publication date: March 11, 2021Inventor: Brian Elliot Lemoff

Patent number: 10831269Abstract: A system controls a brightness of an augmented reality (AR) eye-mounted device. The system includes an eye-mounted display, a photodetector system, and a controller. The eye-mounted display includes a contact lens and a femtoprojector. The femtoprojector is contained in the contact lens and is configured to project an AR image to a user's retina. The AR image is overlaid on an external scene viewed by the user through the contact lens. The photodetector system detects a brightness level of the external scene. Based on the brightness level of the external scene, the controller adjusts a brightness level of the AR image projected to the user's retina. In some embodiments, the eye-mounted display receives image data defining the AR image and the controller adjusts a bit depth of the image data based on the brightness level of the AR image.Type: GrantFiled: September 6, 2019Date of Patent: November 10, 2020Assignee: Tectus CorporationInventors: Brian Elliot Lemoff, Michael West Wiemer, Paul Scott Martin, Hansong Zhang, Drew Daniel Perkins

Patent number: 10775884Abstract: An eye-mounted display can be calibrated relative to a user's gaze. A calibration system causes the eye-mounted display to project a calibration image onto the user's retina. The system detects eye movement as the user looks towards the calibration image. Once the detected eye movement indicates that the user's gaze is centered gaze on the calibration image, the system determines a calibration parameter representative of the user's gaze or the detected eye movement. The calibration parameter can be, for example, a pixel offset relative to an initial image source location or an image source pixel corresponding to the user's centered gaze. Subsequent images are then projected by the eye-mounted display onto the user's retina based on the calibration parameter.Type: GrantFiled: May 11, 2018Date of Patent: September 15, 2020Assignee: Tectus CorporationInventors: Gregory David Miller, Brian Elliot Lemoff

Publication number: 20200271957Abstract: 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: ApplicationFiled: February 5, 2020Publication date: August 27, 2020Inventors: Babak Jamshidi, Flint Orin Hamblin, Brian Elliot Lemoff, Michael West Wiemer

Patent number: 10673414Abstract: An augmented reality system including a source and a contact lens display can be used to project information from the contact lens display onto the retina of the wearer's eye. The source provides energy to the contact lens display and operates at a source frequency. The source includes a source circuit including a conductive coil. The contact lens display includes a resonant circuit including another conductive coil and a capacitive circuit. The resonant circuit receives energy from the conductive coil of the source via a magnetic field inductively coupling the conductive coils. The contact lens display additionally includes a feedback circuit to adjust the capacitance of the capacitive circuit to control a resonant frequency of the resonant circuit. The feedback circuit can control the capacitive circuit to maintain the resonant frequency of the resonant circuit near the source frequency as the wearer's eye blinks.Type: GrantFiled: February 5, 2018Date of Patent: June 2, 2020Assignee: Tectus CorporationInventors: Brian Elliot Lemoff, Gregory David Miller, Ion Opris, Hawk Yin Pang
