Single-chip microcomputer(SCM) Temperature Light iIn view of domestic scientific and technological achievements at present,real-time control circuit for greenhouse temperature and light intensity has been designed in line with the principle of cost saving and easy control.With advanced temperature sensor...
1. A LED driver circuit, comprising: a control circuit, generating a LED current for controlling the LED; a first resistor, connected to the control circuit for determining the value of the LED current; a control terminal of the control circuit, coupled to receive a control signal fo...
A light emitting diode circuit with an emitter coupled logic (ECL) interface is provided with temperature compensation by a series circuit consisting of a pair of resistors which are separated by at l
A unique property of photothermal effect-based shape-memory polymers (SMPs) is demonstrated using a chemically cross-linked poly(ethylene oxide) (PEO) loaded with a small amount (0.5 wt %) of gold nanoparticles (AuNPs). We show that controlled surface plasmon resonance absorption of AuNPs allows...
In summary, we have demonstrated temperature-controlled asymmetric transmission of linearly polarized THz waves. By exploiting the insulator-to-metal phase transition of VO2, we switch a metamaterial structure between anisotropic 3D-chiral and isotropic achiral configurations, which turn the transmission as...
However, the time instant of extraction could not be selected simultaneously to light emission, since all SiC MOSFETs of the power switching circuit do not emit light simultaneously. EL extraction from SiC MOSFET has also been implemented in high voltage applications, such as traction inverters, ...
The radiometric calibration target (the CRP) is a white balance card that provides the reflectance properties of the card across the spectrum of light captured by the Altum. The process included the user holding the drone over the CRP and taking an unshaded image of the CRP to discern the ...
when the external voltage of LiB is dropped to 2.7 V where it is set as the voltage where all the stored charges are discharged, the actual voltage within the LiB is actually higher than 2.7 V and hence not all the stored charges in the cell are extracted to the external circuit....
ARAMIS digital speckle is a non-contact measurement system that is capable of measuring the three-dimensional deformation of the specimen using the natural light or white light. ARAMIS can identify the surface of the tested specimen using the camera images where different coordinates are being assigne...
All parameters setting can be saved after short circuit.Relay output.High Control precision 0.1 centigradeCan be used for domestic freezer, water tanks, refrigerator, industrial chiller, steamer, industrial equipment and other temp...
