Thermal imaging cameras.
Convert invisible infrared radiation into visible images.
the fire and rescue services used this to seek people who are trapped in a burning building or to locate hidden fires/hot spots and to check that fires are properly extinguished.

Once an image has been picked by the camera it is taken to the monitor and then recorded on video tape or DVR. The ability of the camera to zoom in and out is determined by the type of lens it has. 

 CCTV helps protects people’s homes/ businesses/ properties. All public services will use CCTV but for different reasons. For example policemen/ paramedics have CCTV on their car recording on call incidents.  An example of when the Fire Service use CCTV when they are called to a fire they may use nearby cameras to see if they have evidence to how the fire was set etc.

Positives-  It will reduce crime and it has 24 hour protection. Alert people and will be safer.

Negatives- People cant have privacy and it could get expensive when buyin the cameras.

Basically you wear a tag if you’ve done something bad but not bad enough to be jailed for an example anti-social behaviour. The time length of wearing them can be different depending what you have done the minimum is a month but you can wear it for much longer such as 6 months onwards. 

A tag doesn’t allow the police to track you, it just alerts them if you are out past curfew. Curfew times can vary normally between 6pm-9pm they have to be home. Police officers get alerted if not, they also get alerted if the tag has been tampered with, like if someone has tried to cut it off.

As they pass through the body, the energy from X-rays is absorbed at different rates by different parts of the body. A detector on the other side of the body picks up the X-rays after they've passed through and turns them into an image.

Regton Security Metal Detectors can help with the following:
 

airplanes or into other secure places such as prisons and hospitals) and in many kinds of scientific research. Archeologists often frown on untrained people using metal detectors to disturb important artifacts but, used properly and with respect, metal detectors can be valuable tools in historic research.~

Select an airport from any of our ten destinations, the time of day and weather conditions, and pilot the plane through a take-off, landing or advanced landing.

flight simulator is a device that artificially re-creates aircraft 

flight and the environment in which it flies, for pilot training, design, or other purposes. It includes replicating the equations that govern how aircraft fly, how they react to applications of flight controls, the effects of other aircraft systems, and how the aircraft reacts to external factors such as 

air density, turbulence, wind shear, cloud, precipitation, etc. Flight simulation is used for a variety of reasons, including 

flight training (mainly of pilots), the design and development of the aircraft itself, and research into aircraft characteristics and control handling qualities

It is essential that fire crews attending this variety of calls are able to access as much information relating to the individual call-outs as possible. 

When you use another mobile network to access the internet on your phone while still being billed by your normal provider. It can be pricey, so many experts advise people to turn data roaming off while they are abroad. You can then switch data roaming on and off.

•What is it? An X-ray machine is a device that produces X-rays. It is commonly used in a variety of applications including medicine, fluorescence, electronic assembly inspection, and measurement of material thickness in manufacturing operations. In medical applications, X-ray generators are used by radiographers to acquire x-ray images of the internal structures (e.g., bones) of living organisms, and also in sterilization.

•How does it work? An X-ray machine generally contains an X-ray tube to produce the X-rays. The heart of an X-ray machine is an electrode pair, a cathode and an anode, that sits inside a glass vacuum tube. The cathode is a heated filament, like you might find in an older fluorescent lamp. The machine passes current through the filament, heating it up. The heat sputters electrons off of the filament surface. The positively-charged anode, a flat disc made of tungsten, draws the electrons across the tube. 

•How can it be used? X-rays are recorded on film or recorded digitally. A radiologist, who is a physician with specialized training in X-ray and other imaging tests, will analyze and interpret the results of your X-ray and then send a report to your personal physician.

•Advantages? 

– X-ray exam is fast and easy and the equipment used is relatively inexpensive and widely available.

•Disadvantages? – Women should inform their doctor if they are or may be pregnant or nursing prior to any radiological imaging. Your doctor may recommend another type of test to reduce the possible risk of exposing your baby to radiation. Also there is a rare risk of a major allergic reaction to the contrast agent.

Resonance frequency is the key factor in a geophone, and it has to be low for the measurement of low-frequency signals. On the other hand, geophone must exhibit high bandwidth to measure high-frequency signals as well. However, most of the currently available geophones include mechanical springs that decrease the performance of the device

Sometimes an X-ray exam includes contrast. For a contrast study, you will receive a drug called a contrast agent, which will highlight or contrast parts of the body so they show more clearly on the X-ray image.

Example of Uses:       X-ray exams can be used to view, monitor, or diagnose

•What is it? A PASS device (Personal Alert Safety System) also known as a ADSU (Automatic Distress Signal Unit), is a personal safety device used primarily by firefighters entering a hazardous environment such as a burning building.

•How does it work? The PASS device sounds a loud audible alert to notify others in the area that the firefighter is in distress. Older models required the wearer to manually signal a distress, whereas modern units retain a manual alarm but also monitor the wearer’s motion via a ball bearing or accelerometer that triggers an alert should the wearer be inactive for a preset amount of time.

•How can it be used? It can be activated manually by the firefighter, or activates automatically if the firefighter stops moving. 

•Advantages? Allows firefighters to not have to rely and shouting and waste their oxygen when they are in smoke.

•Disadvantages? Could not work correctly or be faulty.
