Frequently Asked Questions

Will the signal travel through walls?

Purdue University Calumet | CTIS - Wireless
Yes. CalNet uses radio waves, which can pass through glass and standard walls. It can also travel around corners, so you can still receive a signal on the other side of a more solid barrier (metal and cement are harder for the 2.4GHz signal to penetrate). No. Bluetooth is a 1Mbps (Megabits per second) standard for connecting small devices in close proximity, like connecting a palmtop computer to a cell phone. CalNet uses IEEE 802.

Can the signal go through walls/buildings?

Tangent: Mobile Wireless Classroom, Wireless Lab - FAQ
Yes, it can go through walls and buildings, but it also depends on what the wall is made of or what is in the wall. Walls with sheet metal covering may reflect the signals and the radio waves will not penetrate it. Also walls with lots of wiring and poor wiring insulation may cause interference and a degradation of signal, hence poor performance.

Why can spirits travel through walls?

Untitled Document
One theory is that they are made up of energy and as you know energy is not solid, giving them the ability to travel through a wall. Another one is that if it is a residual haunting, the entity is oblivious to a newly contructed wall etc. Others say, that the spirit is made of fine matter which is less dense than that of a wall.

What is the penetration ability of the signal through walls/ceilings/objects?

BigSecurity.com | Support
Our standard 700 feet LOS (line of site) system can typically penetrate 6-8 interior walls with ranges up to 400 feet and is designed to work comfortably in a 5500 square foot home or office. The signal penetrates most solid objects, including glass, plastic, wood, fiberglass and some metals. The denser a material, the more the signal is weakened.

What are the walls made of?

FAQ
The sink and shower walls are covered with a moisture resistant wallboard. Inside the shower the finished walls have pre-moulded shelves for toiletries. All surfaces are designed to be easy to clean. It's a vitreous china low-flow (1.6 gallon) standard toilet with a great track record. We can also install a 'high mount' toilet which is easier on the knees.

WILL OZONE TRAVEL INTO WALLS AND KILL MOLD INSIDE A WALL?

Frequently Asked Questions about Ozone, Air-Zone Ozone Gener...
If mold is living inside the walls the ONLY way to kill the mold is to take down the wall and then blast the inside of the walls with High Ozone Shock Treatments to make sure it is all dead. Some companies are now saying that they have "specially created" ozone or that they use a form of "negative pressure" that will get the ozone inside of walls to kill the mold and bacteria inside them. This is simply not true.

What do the signal names 'signal 0', 'signal 1', ... mean?

Frequently Asked Questions about PhysioNet
noted in the answers to the previous two questions, signal names recorded in header files describe the signals in each record. In rare cases, however, this information is missing, usually because it was not preserved when the signals were recorded. Names of the form 'signal N' are default signal names used in such cases; they may appear in header files explicitly, or they may be displayed by PhysioToolkit software if no explicit signal names appear in a header file.

What is a signal?

FAQ
Technical indicators generate various types of signals based on such events as the crossing of two lines, a line crossing an important threshold, or a particular pattern such as divergence between the price and the indicator. These events may provide an early warning of a price move and often provide investors with specific buy and sell signals.

How do I crawl on walls?

Natural Selection FAQ
Alien players always spawn in at a hive and as a Skulk. The skulk has the ability to crawl on walls and ceilings. Just look up a wall and move forward. It takes some practice (and some getting used to), but good players will learn to use it to outflank their enemies and move quickly across the map. Wall-running can be disabled by holding the "crouch" key. This can be useful for dropping to the ground or in conjunction with the leap ability.

How do spiders climb walls without falling?

Objective Consulting, Inc. :: Spider Information :: FAQs
According to a BBC science website, some spiders secrete a small amount of the sticky silk they use for their webs onto their feet and use that to move across walls. Other spiders have specially designed feet that allow them to grasp the irregular surface of walls and ceilings. They cannot climb slick surfaces, because their feet have nothing to grasp.

How do cockroaches walk on walls?

Liz, The feet of insects including cockroaches are made up of a brush like pile which reacts with a surface like myriad weak suction cups. The weak forces involve adding together thousands of such individual adhering pillus ends and result in a strong enough force to suspend the body of a fly, a roach or even larger non-insectal critters such as lizards. To step the cockroach must remove the pilli individually in a wave, like ripping off some cellophane or an adhesive bandage.

How do I turn a stereo signal into a mono signal?

Car Audio Installation FAQs - WikiFAQ - Answers to Frequentl...
Creating a mono signal is often necessary when you are powering a subwoofer by bridging the amplifier. Many people do not realize that bridging an amplifier does not always provide a mono signal - many amplifiers will simply use only one input channel, which means that the subwoofer won't be receiving the full signal. Some amplifiers have a switch that will allow you to combine the left and right channels into a mono signal.

What is the format of the signal files?

Frequently Asked Questions about PhysioNet
Many formats are supported. Most signal files are written in "format 212", in which two 12-bit samples are bit-packed into three 8-bit bytes. See signal(5) in the WFDB Applications Guide for details on format 212 and on the other supported formats. To determine which format is used for a given signal file, look in the associated header file. (This is a text file that usually has the same name as the signal file, except for a suffix of .hea instead of .dat.

How can I read signal files?

Frequently Asked Questions about PhysioNet
If you would like to read signal files within a C, C++, Fortran, Java, Perl, or Python program, see the WFDB Programmer's Guide for information on doing this using the WFDB library. Other programming languages supported by SWIG may also be usable with the WFDB library, but have not been tested. Briefly, use isigopen() to open the files, and getvec() to read them.

What is signal conditioning?

PC/104 Embedded Systems FAQ, EBX, Linux, Real Time, data acq...
More generally, signal conditioning is converting a signal from some transducer to whatever your receiving system needs. Frequently it's a matter of amplifying the microvolt or millivolt signals you get from (for instance) a strain gauge to the 10V span you need to get good resolution for your analog to digital converter. However, many transducers give you strange things that you have to convert.

How do I find my own signal on AO-40?

AO-40 FAQ
Check that AO-40 is in range and in the correct mode for the equipment you plan to use. e.g. U/S bands Tune your receiver to the beacon frequency on 2401.323 MHz +/- Doppler shift, and peak this signal by moving your antennas. Next, tune your transmitter to a frequency that corresponds to a quiet area of the transponder. Make sure you stay clear of the beacon! This is important as you will not be popular if you cause QRM to other users or interrupt the telemetry.

How strong is the signal?

University Radio Hilo & Campus AM FAQ
This depends on where you are. If you are on campus, it is best in the areas around the Theatre. The UHH campus is mostly covered. The HawCC campus is covered with decent reception; if you have a good radio you can get it better. There are spots around town where the signal is good, and other spots where it does not reach. The signal comes in most clearly away from powerlines.
