more IT in modern application through sensors

Third application: municipal surveillance

Municipal surveillance is the constant monitoring behaviour using surveillance tools to gather information about a specific location such as a city. Surveillance is the monitoring of behaviour, many activities, or information for the purpose of information gathering, influencing, managing or directing.

This can include observation from a distance by means of electronic equipment, such as closed-circuit television (CCTV), or interception of electronically transmitted information like Internet traffic.

example: facial recognition

Facial recognition identifies unique features and patterns of an individual’s facial appearance. Face recognition systems use computer algorithms to pick out specific, distinctive details about a person's face.

These details, such as distance between the eyes or shape of the chin, are then converted into a mathematical representation and compared to data on other faces collected in a face recognition database. This tool uses visual sensors to identify the data that it collects if first must have an optical view of the subject and it also cannot work without a camera.

example: spy cameras

These devices are used to collect non-consensual visual data and information about a subject. A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image. When all those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image. This tool uses visual sensors since it relies on camera lenses to capture the specific data that is wants to capture this like images of videos.

examples: listening devices

These devices are used to collect non-consensual acoustic data and information about a subject. A microphone converts sound into a small electrical current. Sound waves hit a diaphragm that vibrates, moving a magnet near a coil. In some designs, the coil moves within a magnet. This tool uses acoustic sensors because the data that it collects is audio. Meaning that it is a microphone that is used in order to record a variety of sounds.

example: close circuit television

This device collects data about public spaces such as municipal areas. CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it. This tool uses visual sensors because the data that it collects are visual data like sound and images.

fourth application: GPS

GPS stands for global positioning system, and it is a utility owned by the United States government which provides its users with navigation services.

Examples of global positioning system uses include:

Location: Determining a position.

Navigation: Getting from one location to another.

Tracking: Monitoring objects or personal movement.

Mapping: Creating maps of the world.

Timing: Making it possible to take precise time measurements.

example: GPS compass

There are two pieces of data this tool collects. The first one is the current direction in which the subject using it is heading towards called the heading. And the second one is the desired direction in which the subject wishes to be called the bearing. This device works by using magnets. A compass works by detecting and responding to the Earth's natural magnetic fields.

example: satellite

There are three main data provided by this tool. The first one is imagery which is all visual information we get from outer space. The second one been communication which is how international networking works. And the third one been navigation. Which is how we can create direction to get from one place to another desired place. A satellite works by sending and receiving microwaves.

This tool can be under visual, positional and weather sensor. Since it is used to capture visual data such as images but also to track and identify location meaning that it also falls under positional. And it is also used to identify weather changes in a specific location which is mainly the planet earth meaning that meaning that it also falls under weather.

example: altimeter

This is a device that is designed to measure a specific altitude. An altitude is the vertical height of an object at a given location.

An altimeter works by measuring air pressure, utilizing the fact that the air pressure of the atmosphere decreases by approximately 1 millibar for each 10 meters in height.

This tool is false under positional since it is used to measure a specific distance from one point to the other in the forms of heights of altitude.

example: GPS alarm clock

A fully mobile alarm with GPS tracking is a personal alarm that can be taken and used anywhere. A GPS alarm works by been connected to the internet. A GPS alarm can be classified under positional sensor because it relies on a GPS system which identifies what is the movement orbit of the earth to identify what time it is.
