TEMPERATURE SENSING USING OPTICAL SENSORS (18191824)

Main Inventor

Wegene H. TADELE

Brief explanation

This abstract discusses the use of LEDs and photodiodes on a device that comes in contact with a user for temperature sensing. By applying different bias currents to the LEDs and PDs and measuring the resulting diode base-emitter voltages, changes in voltage can be used to estimate the user's temperature. A measurement circuit with a current source or sink, amplifier, and ADC can be connected to each LED and PD to obtain these measurements. The differences in voltage measurements can then be used in equations to estimate the user's temperature.

Abstract

This relates to using light emitting diodes (LEDs) and/or photodiodes (PDs) on a device intended to come in contact with a user for temperature sensing. In some examples, the LEDs and PDs can be used for both biometric sensing and user temperature sensing. By biasing the LEDs and PDs with different bias currents and obtaining different diode base-emitter voltages (V) having known negative temperature coefficients, changes in V (ΔV) can be computed and used to estimate user temperature. In particular, a measurement circuit including a current source or sink, an amplifier, and an analog to digital converter (ADC) can be connected to each LED and PD. Different bias currents can be applied to the LEDs and/or PDs (the PDs being forward-biased instead of their normal reverse-biased mode for biometric sensing) to obtain different V measurements, and those differences can be used in equations to estimate the temperature of the user.

Configurable array of single-photon detectors (18337064)

Main Inventor

Nadav Fine

Brief explanation

The abstract describes a method for optical sensing that involves sending a series of light pulses towards a target scene and capturing the reflected light using an array of single-photon detectors. These detectors produce electrical pulses in response to the incoming photons. The electrical pulses are then counted in different time intervals that are synchronized with the light pulses. The time intervals include a first and second interval with different delays relative to the light pulses. The delays are varied over a sequence of different delay times during the series of light pulses. By comparing the counts of electrical pulses in the first and second intervals, the time it takes for the light pulses to travel to the target scene and back (time of flight) can be calculated.

Abstract

A method for optical sensing includes directing a series of optical pulses toward a target scene and imaging optical radiation that is reflected from the target scene onto an array of single-photon detectors, which output electrical pulses in response to photons that are incident thereon. The electrical pulses output by the single photon detectors are counted in multiple different gating intervals that are synchronized with each of the optical pulses, including at least first and second gating intervals at different, respective delays relative to the optical pulses, while the delays are swept over a sequence of different delay times during the series of the optical pulses. A time of flight of the optical pulses is computed by comparing respective first and second counts of the electrical pulses that were accumulated in the first and second gating intervals over the series of the optical pulses.

Optical Systems for Providing Polarized Light to a Waveguide (18188322)

Main Inventor

Vikrant Bhakta

Brief explanation

The abstract describes a display that uses a waveguide to provide light to a specific viewing area. The display includes structures that recycle polarization, allowing for maximum efficiency of the light transmission. These structures consist of a polarizing beam splitter and a prism, which separate the light into two portions with different polarizations. One portion is transmitted as image light, while the other portion is reflected. Waveplates are used to align the polarizations of the two portions of light before they are coupled into the waveguide. This ensures that the maximum amount of image light is transmitted into the waveguide, optimizing the display's performance.

Abstract

A display may include a waveguide for providing light to an eye box. The display may include polarization recycling structures having a polarizing beam splitter and a prism. The polarizing beam splitter may transmit a first portion of unpolarized light as first image light having a first polarization and may reflect a second portion of the unpolarized light as second image light having a second polarization. One or more waveplates may be mounted to the prism for transmitting the second image light. Upon transmission by the waveplate(s), the second image light may have the same polarization as the first image light. An input coupler may couple the first and second image light into the waveguide. Providing polarized light to the waveguide may maximize the optical efficiency of the waveguide. The polarization recycling structures may maximize the amount of the image light that is coupled into the waveguide.

Systems With Window Illuminators (18337360)

Main Inventor

David E. Kingman

Brief explanation

The abstract describes a system that includes windows with a special type of glass called laminated glass. These windows separate the inside and outside of a vehicle. Inside the window, there is a light guide illuminator that provides illumination for the interior of the vehicle. The light guide receives light from a light source and has structures that scatter light. These scattering structures become denser as you move away from the light source, ensuring that the interior illumination is even across the light guide. Additionally, there may be an adjustable optical component layer, like a light modulator or haze compensation layer, placed between the light guide and the laminated glass. This layer has scattering structures that become less dense as you move away from the light source.

Abstract

A system may have windows. A window may have a structural window layer such as a structural window layer formed from laminated glass layers. The window may separate an exterior region from an interior region within the vehicle. A light guide illuminator in the window may provide illumination for the interior region. The light guide illuminator may have a light guide that receives light from a light source. The light guide may have a density of light scattering structures that increases as a function of increasing distance from the light source so that the interior illumination is uniform across the light guide illuminator. An adjustable optical component layer such as a light modulator and/or a haze compensation layer with a density of light scattering structures that decreases as a function of distance from the light source may be interposed between the light guide and the structural window layer.

Display System (18212799)

Main Inventor

Fletcher R. Rothkopf

Brief explanation

This abstract describes a display system that consists of a head-mounted display unit and a wake control system. The head-mounted display unit is capable of providing content to the user in two different power states: a low-power state and a high-power state. The high-power state consumes more power but provides the content with better quality. The wake control system is responsible for determining when to switch to the high-power state. It does this by assessing certain wake criteria. Initially, it assesses a first wake criterion with low power. If this criterion is satisfied, it then assesses a second wake criterion with higher power. If the second wake criterion is also satisfied, the wake control system triggers the head-mounted display unit to operate in the high-power state.

PROGRAMMABLE DIGITAL-TO-ANALOG CONVERTER DECODER SYSTEMS AND METHODS (18338920)

Main Inventor

Yi Zhao

Brief explanation

The abstract discusses the use of a digital-to-analog converter (DAC) and the variations that can occur in the analog output depending on which unit cells are activated. Each unit cell in the DAC is generally the same, but factors such as non-linearity or noise can affect the output. The fill order, or the order in which the unit cells are activated, can impact the linearity and noise of the DAC. To address this, the decision units in the DAC can be programmed to select which branches to activate, allowing for changes in the fill order based on a fill-selection signal. This flexibility in fill order can account for manufacturing variations, supply voltage gradients, output line routing, and environmental factors like temperature.

Abstract

A number of unit cells of a digital-to-analog converter (DAC) may be simultaneously activated to generate an analog signal. However, while each unit cell may be generally the same, there may be variations such as non-linearity or noise in the analog output depending on which unit cells are activated for a given digital signal value. For example, as additional unit cells are activated for increased values of the analog signal, the fill order in which the unit cells are activated may affect the linearity/noise of the DAC. The decision units may be programmable to select which branches of the fractal DAC to activate, changing the fill order based on a fill-selection signal. The fill order may be set by a fill controller via the fill-selection signal to account for manufacturing variations, gradients in the supply voltage, output line routing, and/or environmental factors such as temperature.

Communication Between Devices During Wireless Power Transfer (18341538)

Main Inventor

Jeffrey D. Louis

Brief explanation

This abstract describes a wireless power system that consists of a transmitting device and a receiving device. These devices can communicate with each other using in-band communication.

Communication Coordination and Reduced Processing Techniques for Enhanced Quality of Service Procedures (17785387)

Main Inventor

Pavan Nuggehalli

Brief explanation

This abstract describes a system where a base station receives data packets from a network node, which contain reflective quality of service (QoS) indicator markings. The base station uses these markings to determine the active uplink (UL) QoS rules associated with a user equipment (UE). It also considers timers, status information from the UE, and the active UL QoS rules to decide whether to include or exclude the RQI markings in the transmission of the data packets to the UE. If it determines that the RQI markings should be included, the base station transmits the packets with the RQI markings to the UE.

Abstract

A base station (BS) may receive, from a network node, one or more data packets including one or more reflective quality of service (QoS) indicator (RQI) markings. The base station may then determine, based on a value of the one or more RQI markings, one or more active uplink (UL) QoS rules associated with a user equipment (UE). The base station may further determine, based on at least one of one or more timers, the one or more active UL QoS rules, and status information received from the UE, to include or refrain from including the one or more RQI markings in a transmission of the one or more data packets to the UE. Accordingly, in response to the determining that the RQI markings should be included, the base station may then transmit the one or more packets including the RQI markings to the UE.

Main Inventor

Qiming Li

Brief explanation

This abstract describes a technology that allows a user device (UE) to switch between different communication protocols in a frequency range above 24 GHz. The UE can inform a base station that it is capable of performing this type of handover. The UE then receives a command from a target cell to switch from a source cell to the target cell. During the handover process, the UE continues to maintain a data connection with the source cell. It performs measurements on the target cell and then goes through a physical random access channel procedure. Finally, the UE receives a command from the target cell to release the data connection with the source cell.

DYNAMIC MAXIMUM TRANSMISSION POWER (17720581)

Main Inventor

Lorenzo Bertizzolo

Brief explanation

This abstract describes a wireless communication device that receives a limit on the average power it can transmit over a certain period of time. It sets an initial maximum transmission power based on this limit and transmits a signal using this power. If the actual transmission power used is lower than the initial limit, the device calculates the remaining power and adds it to the initial limit to determine a new maximum transmission power for the next transmission. The device then transmits a signal using this new limit.

Abstract

A wireless communication device receives an average transmission power limit for a time period, and determines a first MTPL for a first time of the time period by setting the first MTPL to the average transmission power limit. The wireless communication device then transmits a signal at the first time using a first transmission power not to exceed the first MTPL. If the first transmission power is less than the first MTPL, then the wireless communication device determines residual transmission power based on a difference between the first MTPL and the first transmission power. The wireless communication device determines a second MTPL for a second time of the time period by adding the residual transmission power to the first MTPL. The wireless communication device then transmits a signal at the second transmission power not to exceed the second MTPL.

Displays Having Transparent Openings (18006519)

Main Inventor

Yuchi Che

Brief explanation

This abstract describes an electronic device that has a display and an optical sensor underneath the display. The device has transparent windows that overlap the sensor, which can reduce the resolution of the display in some areas. To address this issue, the device uses two sensors with different patterns of transparent windows to sense light. These different patterns result in different diffraction artifacts. By comparing the images captured by the two sensors, the device can correct for these artifacts and improve the overall image quality.

Abstract

An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To mitigate diffraction artifacts, a first sensor (-) may sense light through a first pixel removal region having transparent windows arranged according to a first pattern. A second sensor (-) may sense light through a second pixel removal region having transparent windows arranged according to a second pattern that is different than the first pattern. The first and second patterns of the transparent windows may result in the first and second sensors having different diffraction artifacts. Therefore, an image from the first sensor may be corrected for diffraction artifacts based on an image from the second sensor.
