Abstract: To mitigate undesirable outcomes due to crosstalk in an ambient light sensor reading resulting from light emission from an electronic display, statistics may be gathered to determine and compensate for the crosstalk. For example, the ambient light sensor may detect ambient light levels while the electronic display is temporarily paused to reduce or eliminate crosstalk between the light produced by the electronic display and the ambient light sensor. However, the ambient light sensor may retain charge from a previous light emission, creating back-emission crosstalk. The ratio of back-emission to front-emission (e.g., present light emission) may not be linear, and the degree of nonlinearity may vary with pixel value, color component, display brightness, temperature, and so on. As the ambient light sensor is affected by back-emission, compensation for the nonlinearity between the front-emission and the back-emission may be obtained to estimate the crosstalk induced on the ambient light sensor.

Abstract: Disclosed is a device for inspecting optical power measurement of a light emitter, the device including: a reference light emitter; a measurer configured to measure optical power by receiving light emitted from one of the reference light emitter and a plurality of inspection target light emitters, the measurer including an integrating sphere, a photodiode detector, and a photocurrent or photovoltage measurement device; and a controller configured to calculate a first average of optical power of the plurality of inspection target light emitters by measuring first optical power of a first inspection target light emitter among the plurality of inspection target light emitters, and generate an alarm to stop using the measurer when a difference between the first average and a second optical power of the reference light emitter exceeds a first threshold. Thus, the inspection is more accurately and reliably carried out.

Abstract: An opto-isolator has a light emitter, at least one light guide, a light recorder optically connected to the light emitter via the light guide, an optical signal modulator optically connected to the light emitter, the light guide or the light recorder, and an optical modulator memory connected to the optical signal modulator. The optical signal modulator modulates an optical signal within the opto-isolator, and is controlled by the optical modulator memory.

Abstract: Techniques for low power indoor/outdoor detection are disclosed. In the illustrative embodiment, an integrated sensor hub receives data from an accelerometer. The sensor hub processes the accelerometer data to determine an activity of the user. Depending on the activity of the user, the sensor hub may determine whether the compute device is indoors or outdoors or may receive data from additional sensors, such as a magnetometer, a gyroscope, or an ambient light sensor. The additional sensor data may be used to determine whether the compute device is inside or outside.

Abstract: An instrumented substrate may provide a metrology platform for monitoring extreme ultraviolet (EUV) radiation in an image plane of a EUV lithography tool. The instrumented substrate may include in-band dosage sensors. The in-band dosage sensors may generate dosage measurements corresponding to the illumination which is in-band. The instrumented substrate may also include out-of-band dosage sensors and in-band scattered dosage sensors. The instrumented substrate may be housed within a front opening unified pod (FOUP) of a system.

Abstract: An optical sensing device and a method for manufacturing the same are provided. The optical sensing device comprises a substrate, an optical acting area, a filter layer and a carbonized sidewall. The optical acting area is disposed on the substrate. The filter layer covers the optical acting area and selectively allows only a light beam with a specific wavelength to pass therethrough and be received by the optical acting area while blocking the light beams with other wavelengths. The carbonized sidewall covers the sidewall of the filter layer and a portion of the sidewall of the substrate to prevent the light beams with the other wavelengths from being received by the optical acting area through the sidewall of the substrate.
