How fMRI Works Medical technology has come so far in recent years that it's now possible for imaging scans to dissect the body into wafer-thin pictures and create three-dimensional models of organs and tissues to find abnormalities and diagnose disease. Yet a relatively new type of scan c...
Investopedia / Dennis Madamba What Is a Command Economy? A command economy is a key aspect of a political system in which a central governmental authority dictates the levels of production that are permissible and the prices that may be charged for goods and services. Most industries in command...
Driving higher loads from a 555 Timer with an NPN transistor If you want to use a MOSFET on the output, make sure you use a MOSFET with a VGSthat is lower than the output voltage from your 555 timer. The resistor is there to protect the output pin from high spikes of current when t...
Your IC should look like this: Here is what is happening. In TTL, +5 represents a binary "1" and ground represents a binary "0." If an input pin to a gate is not connected to anything, it "floats high," meaning the gate makes an assumption that there is a 1 on the pin. So ...
How a Photovoltic Cell Works. When photons strike a PV cell, they may be reflected or absorbed, or they may pass right through. Only the absorbed photons generate electricity. When this happens, the energy of the photon is transferred to an electron in an atom of the cell (which is actu...
Step 5.1: Place the crystal close to the IC pins Position the crystal as close as possible to the relevant IC pins. This reduces the trace length and helps maintain signal integrity. While placing the crystal, connect it directly to the IC pins using the interactive routing tool (X key) ...
How it works Bendix® ESP® works with vehicle sensors to constantly monitor the status of the chassis and anticipate and adapt to loss-of-control and rollover events. In addition to notifying the driver though automatic alerts, the system can also quickly and automatically intervene to assist...
The Bose QC 35 II headphones are more comfortable than theShure AONIC 50. However, the AONIC 50 headphones has the best noise canceling on the market when it comes to low-frequency attenuation. Additionally, Shure’s headset offers aptX, aptX HD, aptX Low Latency, AAC, and LDAC. But the...
How Integrated Circuit Cards Are Used to Combat Identity Theft Magnetic stripe cardshave been frequently duplicated, allowing identity thieves to create copies of the original card, as well as sell the account information they have illegally accessed. The use of the embedded chip in a payment card...
