Abstract: A readout circuit for an amplitude modulating sensor includes a first and second wavelength light source; an optical coupler coupled to receive a first light signal from the first wavelength light source and a second light signal from the second wavelength light source; a frequency selector that allows for the first light signal to pass to the amplitude modulating sensor; and a detector system coupled to the optical coupler to receive the first light signal and the second light signal after the first light signal is modulated by the amplitude modulating sensor and independently detect the two signals. The detector system generates electronic signals representing the modulated first light signal and the second light signal and removes a common mode signal of the modulated first light signal and the second light signal, removing common mode noise or attenuation in the modulated first light signal.

Abstract: A vehicular cabin monitoring system includes a camera disposed within a cabin of a vehicle. Image data captured by the camera is transferred to and is processed at an electronic control unit (ECU). A light emitter that, when electrically operated to emit nonvisible light, illuminates at least a portion of the interior cabin that is viewed by the camera with nonvisible light. The vehicular cabin monitoring system, via processing at the ECU of image data captured by the camera and transferred to the ECU, determines illuminance of nonvisible light at a region of interest within the illuminated portion of the interior cabin that is viewed by the camera. The vehicular cabin monitoring system, responsive to determining that the illuminance of nonvisible light at the region of interest is greater than a threshold illuminance, reduces intensity of nonvisible light emitted by the light emitter.

Abstract: A system for characterizing a light beam includes a detector that includes at least one detector unit, and a micro-opto-electromechanical system that includes an array of mirrors. Each mirror is switchable between a first sand a second witching states. In the first switching state, the mirror reflects light emitted by a light source onto the detector. In the second switching state, the mirror reflects the light away from the detector. The system further includes a controller configured to cause a beam profile measurement to be performed on the light detected by the detector unit while selectively switching the mirrors between the first and the second switching states, and an optical unit configured to direct the light in a form of two different input light beams onto the micro-opto-electromechanical system. The controller is configured to cause the beam profile measurement to be performed on each of the two input light beams.

Abstract: A method and apparatus for an indoor horticultural system that utilizes a wired network to control lighting. The wired interface is used to relay both analog and digital intensity control information, whereby an analog signal is used to control the intensity of all LED arrays in each lighting fixture during a first mode of operation and a digital signal is used to control the intensity of each individual LED array in each lighting fixture in a second mode of operation. Both the analog and digital signals utilize the same physical interface.

Abstract: A method of improving performance of an averager is provided. The method includes steps of: (a) multiplying a value of a (n−1)th piece of output data by a value “N” to calculate a temporary value; (b) determining whether or not a difference between an nth piece of input data and the (n−1)th piece of output data is larger than or smaller than a zero value, if yes, compensating the temporary value to obtain a correction value and performing step (c), if no, setting the correction value and performing step (c); (c) dividing the correction value by the value “N” to obtain a first value; (d) subtracting the first value from the correction value and adding up the correction value and the nth piece of input data to obtain a second value; and (e) dividing the second value by the value “N” to calculate an output value of the averager.

Abstract: A handheld system for the objective measurement of compliance with a clinical study protocol, such as an ETDRS BCVA study protocol. The system and methods use a handheld device application and associated sensors of the device to measure ambient light, and the distances between objects in an examination lane to determine compliance. The system may also identify objects in the room and provide an interface for users to understand compliance and receive training.

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: Estimating a propagation environment of a radio wave using a scale model. The method includes the following steps. The scale model is created. In the scale model, a light source capable of emitting directional light and scanning an irradiation direction is installed, regarding the light source as a transmission station of a radio wave. The light source scans an inside of the scale model, and a center light generation state in which center light directed to a measurement point set in the scale model is generated is detected in a process of scanning. A light receiving sphere is installed such that a center coincides with the measurement point. A direction connecting a position of an irradiated point appearing on the light receiving sphere and a position of the center under the center light generation state is estimated as an arrival direction of the light reaching the measurement point.

Abstract: Light mapping devices and systems for use in indoor or vertical farming are disclosed herein. In particular, a light detection device is provided that includes a plurality of light sensors configured for detecting light emitted from one or more light sources at distinct positions across a grow plane. The light detection device will also include a microcontroller and one or more signal routing circuit boards, or junctions, for making electrical connections between the light sensors and the microcontroller in a multiplex architecture to enable the microcontroller to cycle through and read the Lux values from each of the light sensors with sub-second frequency and in real-time. The light detection device may also be part of a light mapping system that converts the Lux values to PPFD and generates a heatmap of PPFD intensity at distinct locations across the grow plane. Also provided herein are methods of using the light detector device and/or the light mapping system to determine the PPFD distribution across a grow plane in 2-dimensions or 3-dimensions in order to adjust the lights and/or position of growing plants, if necessary, to ensure that each plant in the grow bed receives sufficient light for optimal growth.
