optical technology is employed in fiber optic sensors to detect and measure various physical parameters like temperature, pressure, strain, and chemical concentrations. by utilizing the interaction of light with
It is good practice to measure this parameter to verify that the resolution of an ADC is not degraded too much by its implementation and configuration. The ENOB can be determined by several methods. In the context of this document, a formula that ...
A detector is used to measure the time this reflection took to return. By knowing the speed of light and round-trip time of the laser pulse, the distance can be calculated. Generally, the higher the amplitude of the pulsed laser, the larger the return signal will be. For long-range ...
CMOS (Complementary Metal-Oxide Semiconductor) is a digital device for capturing light and converting it into electrical signals. It has a photodiode and a transistor switch for each pixel. When light strikes the pixel, it creates a voltage proportional to intensity...
Recently, wearable devices that can quickly and accurately measure BP have gained great attention towards early detection of hypertension.13., 14. In contrast to the conventional method, which records the information about blood pressure via auscultation or a sensor by applying external pressure, the...
Figure 1. Internal power switch buck selection table showing the output current as a selection parameter. Compare Figure 1, a selection table of internal power switch bucks, to Figure 2, a selection table of internal power switch boosts. In the boost table, output current does not...
During measurements, the GUI remotely changes the PFC mode in order to measure the reported power. If the mode change fails (especially at full load), check the PFC behavior: if the PFC SW OVP is triggered, try to increase the "PFC Ki" and "PFC Kp" parameters, while if...
Once you know the expected location of the projector and screen, you can measure the approximate "throw distance" between the projector lens and the screen surface. This is a critical piece of information you'll need to choose a projector. Later on, you can useProjectorCentral's Throw Calcula...
A Coolidge tube’s method of operation deviates not too far from that of a diode. The heater is given a bit of current to warm it to incandescence, where the now hot tungsten cathode boils off a cloud of electrons while simultaneously focusing them into a beam. These electrons are then ...
an RC snubber (CSand RSin Figure 1) is to measure the period of the ringing at the LT3999’s SWA and SWB pins when its switchers turn off without the snubber, and then add capacitance—starting with something in the range of 100pF—until the ringing period lengthens by 1.5x to 2x. ...
