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.

Abstract: A photoelectric conversion device includes a photodiode configured to perform avalanche multiplication, a recharging circuit configured to perform a recharging operation to bring the photodiode after the avalanche multiplication into a state in which the avalanche multiplication can be performed again based on a first control signal including pulses that periodically repeat transitions from a first level to a second level, and a counter configured to count the number of occurrences of the avalanche multiplication by being enabled based on a second control signal. Before the counter is enabled based on the second control signal, the first control signal transitions from the first level to the second level and transitions from the second level to the first level.

Abstract: A pixel disclosed includes an anti-blooming injection transistor (DI) transistor under the control of a BDI amplifier/transistor combination. The “turn on” of the anti-blooming injection transistor is offset from the turn on of the BDI transistor by an offset. When the offset is overcome, excess charge can be diverted (iDiverted) away from an integration capacitor. This can allow the BDI transistor/amplifier combination to hold the detector at nominal bias over an extended range and may reduce blooming. The pixel can be implemented in manner that adds a second transistor and a capacitor to prior BDI designs.
