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: 11077308Abstract: Certain embodiments of the present technology relate to temperature sensors for using in an implantable medical device, and methods for use therewith. Such a method can include alternating between producing a first base-to-emitter voltage drop (VBE1) and a second base-to-emitter voltage drop (VBE2), and alternating between using a capacitor to store the VBE1, which is complimentary to absolute temperature (CTAT), and using the same capacitor to store a ?VBE=VBE2?VBE1, which is proportion to absolute temperature (PTAT). The method also includes using a sigma-delta modulator that includes the capacitor to produce a signal having a duty cycle (dc) indicative of the ?VBE stored using the capacitor, and producing a temperature measurement based on the signal having the duty cycle (dc) indicative of the ?VBE.Type: GrantFiled: October 25, 2018Date of Patent: August 3, 2021Assignee: Pacesetter, Inc.Inventors: Ion Opris, Dean Andersen

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

Patent number: 10580349Abstract: An eye-mounted display includes a femtoprojector, which includes a backplane and a frontplane. The backplane receives data (e.g., data packets) that specify the image to be projected by the eye-mounted display. It converts this data to drive signals (e.g., current) to drive the frontplane. The frontplane contains an array of light emitters (e.g., LEDs) that produce light according to the drive signals, thus generating the desired image. In one approach, the image is deconstructed and transmitted to the backplane as needed as microframes which are displayed asynchronously and only for regions where the image has changed, rather than continuously scanning full picture frames at the full frame rate. In another aspect, the femtoprojector has variable pitch between adjacent light emitters.Type: GrantFiled: February 9, 2018Date of Patent: March 3, 2020Assignee: Tectus CorporationInventors: Paul Scott Martin, Renaldi Winoto, Ion Opris, Mihai-Costin Manolescu

Patent number: 10349161Abstract: A circuit for biasing a transducer including a first plate and a second plate includes a front-end buffer and a charge pump. The front-end buffer generates an internal signal at an internal node in response to a voltage signal of the second plate. The transducer receives the incident sound wave at the first plate to generate the voltage signal at the second plate. The charge pump boosts the internal signal into a boost voltage at the first plate according to a first clock signal.Type: GrantFiled: October 12, 2017Date of Patent: July 9, 2019Assignee: FORTEMEDIA, INC.Inventors: Ion Opris, Abu Hena M Kamal, Ramesh Prakash, Lee Tay Chew

Patent number: 10250980Abstract: A digital microphone is provided. The digital microphone includes an acoustic sensor, a bias generator, first and second attenuators, a buffer, an amplifier, an ADC, and a controller. The acoustic sensor transfers an acoustic signal to a voltage signal. The bias generator provides a bias voltage to the acoustic sensor. The first attenuator attenuates the voltage signal by a first attenuation value. The buffer buffers the voltage signal to generate a buffered voltage signal. The amplifier amplifies the buffered voltage signal to generate an amplified signal. The ADC converts the amplified signal to a data signal with a digital format. The second attenuator attenuates the data signal by a second attenuation value. The controller determines whether the amplified signal is larger than a reference value and adjusts the bias voltage and the first and second attenuation values of the first and second attenuators according to the result determined by the controller.Type: GrantFiled: October 11, 2017Date of Patent: April 2, 2019Assignee: FORTEMEDIA, INC.Inventors: Ion Opris, Abu Hena M Kamal, Lee Tay Chew, Ramesh Prakash, Shomo Chen, Qiang Wei, Lung-Chu Joseph Chen
