However, in comparison to DIFF measurements (highest diffuse irradiance with negligible direct irradiance), we found significant differences in NDVI from SUN and VAR conditions for both classes. For CRI, under highly variable illumination, we found no significant difference between canopy and herbaceous...
The lighting will replace 21 Xenon spotlights that have illuminated the falls for the last 20 years. The new lighting system features more than 100 panels containing 12,600 LED lights that will provide 2-3 times the lighting intensity levels of the xenon spotlights they replace. The LED light ...
for a virtual-reality experience, the display device may be an opaque light-emitting diode (LED) display, a liquid crystal display (LCD), a micro-electromechanical system (MEMS) scanner display system, or any other suitable type of opaque display device. In some implementations...
The similarity of the operation of Wollaston prism to a Ronchon prism and to a single birefringent crystal of quartz or calcite is also disclosed. A comparison viewer illustrated in U.S. Pat. No. 3,450,480 discloses a mechanism which can be manipulated to provide either stereoscopic or mono...
Methods and systems are provided for illuminating various materials using an LED system. These methods and systems can be applied to a plurality of materials, including biological e
(X, Y, Z)target provided by an external input 18, wherein the color point may for example be expressed by CIE tri-stimulus values. Based on the result of this comparison, the color control unit 16 sends adjusted drive signals to the LED drivers 17, which are coupled to the LEDs Ll,...
At the conclusion of the blanking period the ramp and comparison of decoded image data begins. At a time shortly after the beginning of the ramp, the red LED is turned on. Halfway through the ramp, for this exemplary pixel displaying 50% brightness, the comparator detects equality of the ...
The values of the heartbeat and SpO2 are then stored alongside the comparison data from the reference monitor. 3. Experimental Setup The various hardware components described above were integrated into an Incubator 8000 IC (Drägerwerk AG & Co KGaA, Lübeck, Germany). To evaluate the camera-...
