RC Circuits: Charging A Capacitor01:30

RC Circuits: Charging A Capacitor

4.6K
A circuit containing resistance and capacitance is called an RC circuit. A capacitor is an electrical component that stores electric charge by storing energy in an electric field. Consider a simple RC circuit having a DC (direct current) voltage source ε, a resistor R, a capacitor C, and a two-way position switch. In the circuit, the capacitor can be charged or discharged depending on the position of the switch.
When the switch is moved to connect the battery, the circuit reduces to a simple...

Design Example

563
The innovation of touch-tone telephony revolutionized the telecommunications industry by replacing the traditional rotary dial with a dual-tone multi-frequency (DTMF) signaling system. This system uses a matrix-style keypad with buttons arranged in four rows and three columns, creating 12 distinct signals each assigned to a pair of frequencies. Each button press results in a simultaneous generation of two sinusoidal tones – one from a low-frequency group (697 to 941 Hz) and one from a...

Light Acquisition02:16

Light Acquisition

9.7K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

    Summary

    A novel coded access optical sensor (CAOS) smart camera effectively images bright targets using code division multiple access (CDMA) mode. This high dynamic range imaging technology offers robust performance in challenging bright light conditions.

    Area of Science:

    • Optics and Photonics
    • Image Sensors
    • Digital Signal Processing

    Background:

    • Traditional imaging systems struggle with bright light, leading to saturation and loss of target detail.
    • High dynamic range (DR) imaging is crucial for applications involving diverse and intense light sources.

    Purpose of the Study:

    • To demonstrate a novel smart camera system capable of high dynamic range imaging in bright target scenarios.
    • To introduce and validate the code division multiple access (CDMA)-mode coded access optical sensor (CAOS) camera.

    Main Methods:

    • Utilized a hybrid camera design integrating a CMOS sensor and a digital micro-mirror device (DMD).
    • Employed DMD starring mode for initial unsaturated image acquisition, followed by time-modulated CDMA-mode for robust imaging.
