Abstract: An illuminance calibrating device includes a reference light source and an illuminance detection device. The reference light source, which generates light with a specific wavelength and a source illuminance, adjusts the source illuminance to be a first illuminance according to a control signal. The illuminance detection device includes a shading plate, an illuminance detector, and a controller. The shading plate is configured to lower the first illuminance to a first shading illuminance. The illuminance detector detects the first shading illuminance to generate a detection signal. The controller generates the control signal and calculates a ratio of the first illuminance to the first shading illuminance according to the detection signal.

Abstract: Color calibration for digital pathology is provided. A standard glass slide is prepared with a specimen having zero or more stains. The specimen is scanned a first time using a hyperspectral imaging system to produce a first digital image having XYZ color values. The specimen is scanned a second time using a digital pathology imaging system to produce a second digital image having RGB color values. The first and second digital images are then registered against each other to align the digital image data. Individual pixels of the first and second images may be combined in the registration process so that the first and second digital images have substantially similar pixel sizes. A lookup table is generated to associate XYZ color values to RGB color values. Once the lookup table has been generated, it can be used to present RGB color on a display using the corresponding XYZ color.

Abstract: Various implementations disclosed herein includes a method for operating lighting fixtures in horticultural applications. The method may include receiving a user input of a desired irradiance for a first color channel of one or more lighting fixtures that irradiates a plant bed, in which each of the one or more lighting fixtures comprises at least one light emitting diode (LED) array, determining, for each of the one or more lighting fixtures, a PWM setting of the first color channel such that each of the one or more lighting fixtures irradiate the plant bed at the desired irradiance based on calibration data stored in each of the one or more lighting fixtures, and applying, to each of the one or more lighting fixtures, the determined PWM setting of the first color channel.

Abstract: A pulse oximetry measurement system uses a pseudo-random noise generator to stimulate one or more light emitting diodes (LEDs). The light amplitudes from these LEDs, after passing through a part of a body, are detected by a phototransistor or photodiode and digitized with an analog-to-digital converter (ADC). The digitized ADC light amplitude values are re-correlated with the outgoing pseudo-random noise stimulus. Spread spectrum techniques are known for their noise mitigation properties, and ability to pass multiple signals through the same medium without interference. Thus, these measurements can be performed substantially simultaneously with minimal interference from each other. The pulse oximetry measurement system correlates the measured light intensities using pseudo-random noise generation and phase division multiplexing, and computes the measured and correlated peak-to-peak detected light amplitudes to obtain a ratio between these light amplitudes for determining oxygen saturation in the blood, and may also be used for heart rate monitoring.
