Walky talkies aid the Police force in such a massive way, not only whilst trying to contact them to go to a scene of crime but also whilst the crime is being committed, in car chases for example. They work by……… If this technology was not invented or used by the Police force then either crime would be much higher as no one would be able to contact the police men, or the amount of police men employed would be greatly increased to cover a larger distance where their naked eye would be the only tool of their trade
They way in which these devices work is their own hindrance, they are limited to a certain area
A fingerprint scanner works by taking and exact replica 2-D version of a print that is placed on the scanning surface. This enables a positive identification to take place if fingerprints are found at a crime scene. Fingerprints are unique to every person so when a fingerprint has been found and this person is on the offenders database then they can be recognised by the system immediately in most cases with no mistake. Without this technology fingerprints would be no use because with the naked eye most fingerprints do not look much different to others.
The disadvantage of this system is………….
To most people this technology is a nuisance; it slows traffic down, costs people money and aggravates the highly-strung. To others it is a lifesaver, it is true that it slows down traffic, because when they see the cameras they slow to avoid a fine, if they do not slow they get a fine. In the process of slowing traffic it makes it safer for drivers and pedestrians as drivers tend to obey the actual speed limit for which it is safe to travel on that particular piece of road. This technology aids police in catching speeders when they do not expect it. It works as a hand held device………..
The disadvantage with this technology is that the police men cannot be everywhere at the same time so speeders cannot be watched over constantly, as the devise is hand held the operator is required to stand relatively close to the road, this is a hazard as to my knowledge they are frequently on bends in the road, so if a car judges the corner wrongly and goes onto the verge they are likely to hit a Police man.
Call Connect Bus Service
The call connect bus service is a type of taxi which runs in the countryside to connect the villages without a regular bus route with towns that do. To get a bus you have to call the central telephone system and ask for a bus at a certain time and tell them where you are leaving from and your destination. They then contact the busses and find out which is nearest and tell them where to go.
- GPS (Global Positioning System)
A GPS is a navigation device, which uses satellites positioned in the Earths atmosphere to triangulate a fixed position on Earths surface. A most up to date GPS now can use up to 21 satellites in the atmosphere to find a position, but more commonly an 8 satellite GPS is used. In this particular case the GPS is used to determine the position of the busses, it also helps them navigate through unknown places. The job of a GPS receiver is to locate four or more satellites (there are 27 in orbit, 24 working and 3 spares), work out the distance to each satellite and use this information to figure out its location. This is based on a simple mathematical principal called trilateration. Once the receiver has made this calculation to make it more user friendly it converts the raw data into map forms stored in its memory.
The disadvantage with a GPS is that some people may not be aware of how to uses them; although once they have been used a few times the operations become second nature.
Mobile telephones, or mobiles are telephones that can be taken anywhere. They have such capabilities as, a telephone to call people, SMS service, (simple messaging service) using the Internet, playing games and taking and sending photographs and pictures. In this case it is used to give the drivers names and places of where their pick-ups are and the names of the travellers, this helps the driver a lot because he/she can quickly obtain the information they need.
The major drawbacks of this are that mobile telephones can go everywhere but this doesn’t necessarily mean they will work everywhere. With Lincolnshire being the rural county that it is the variety in signal quality is clear to see. In one town the signal may be the best possible, but two miles down the road and signal may become non-existent which stops you from receiving calls or making them
This is the phone number you ring when you would like to book a bus, they then take your details and contact individual busses to give them your information.
The good thing about having a central phone centre for an operation like this is that all of the calls can be processed in the same way with lots of people there. This helps when there’s a query because instead of just one person there are many to confer with, it is also helpful because if the calls were directly to a driver it may cause an accident. It also allows all drivers to be contacted simultaneously to find the closest to you. This can provide jobs for people willing to work in a call centre; this could be a huge impact in certain places.
The only disadvantage I can think of is that you cannot actually speak straight to the driver, this may end up with a message not being heard properly and altered. This could cause major problems.
Spilsby Surgery
- Database of patients records
This database provides the Doctor with all the information he needs when prescribing a drug, for example if he/she prescribes a drug that the patient is allergic to the computer will issue a warning telling the doctor not to administer it. If this were not available then many patients would be given a drug that may be harmful to them or would not work. This database also gives the doctor information of previous prescriptions, illnesses and current medication.
The disadvantage is that with the surgery in Spilsby having used the same computer system for a great number of years it is difficult for them to adapt to new technology although they seem to be getting on very well with the new system a few months on and were able to get to grips with it a few days afterwards.
- Online contact Information
This enables people to find out the telephone number, address and fax number of the surgery. This can prove to be vital when people move into the area from away and need to find out about their local services, all they need to do is type into an online search engine like google a phrase like “Spilsby surgery” and will quickly be able to navigate and find the information needed.
This works by when an order of drugs is delivered it is counted and entered into the database, which then displays a warning saying that the stock is getting low, this alerts the administrative assistants to reorder more stock. This stops the Surgery from ever running out of drugs because if they get close a new order will be made.
The disadvantage with this is that to program it is time consuming with the input of raw data; a way in which it could be improved would be with a bar code scanner, which would speed up the input process, with just a simple swipe it would instantly recognise a specific drug, than all you have to do is type in the quantity
Spilsby Town Hall
- Traffic light noise detector
This works on the principal that when the noise level is not disturbing the neighbours the light lights up green, when it is on the verge of disturbing them it goes amber, and when it gets to red the power is automatically switched off to the PA system and speakers. This is because with the general public in mind this was introduced as many residents around the hall complained about the high volume of functions going on inside. This means that the residents and the hall proprietors can live in peace with one another
Somerfields Supermarket
This works in an identical way to the drug database for Spilsby Surgery, just input the stock and amounts and it will tell you when the stock is getting low. It also has the same time consuming disadvantages.
Automatic doors open as soon as you stand near them, there are different systems, and for example some work on pressure mats, some on motion detecting sensors. The ones in Somerfields works on a proximity device, which measures how far away you are before opening the doors. This makes it easier for disabled or elderly shoppers to get in and out of the shop.
The disadvantage that comes with this is that the doors have to be set back, not to close to the street because people walking past will set the doors off opening and closing, this wastes electricity which in turn is bad for the company (costs more money in electric bills) and bad for the environment (more energy needs to be produced).
