But direct images are rare because exoplanets are dim and hide in the glare of their stars. Researchers at the Observatoire de Paris-PSL, working with Université Grenoble Alpes, used a new tool ...

We present a true random number generator (TRNG) using dark noise of a CMOS image sensor. Because the proposed TRNG is based on the dark characteristics of the CMOS image sensor, it does not require ...

In this letter, we proposed an ultrasonic sensor-based resolution tunable displacement measurement system by using an extension spring. In the proposed method, a linear extension spring is vertically ...
