They are used for security and operations on the streets, airports and train stations. They are used in retail stores to prevent loss and to understand shopper behaviour. Surveillance systems are also used in casinos and museums. They are used in casinos to detect, record and index cheating or suspicious behaviour, find valued customers and banned or ‘watchlist’ customers. Studies show that manual surveillance is impractical due to lack of attention span, increasing number of channels and increasing ‘situation awareness’ needs.
Abstract— In recent years, video surveillance systems become more important to enhance the security and safety of people. These systems can use in various fields such as smart home, office, bank security, monitoring the traffic and in public like shopping malls, railway stations, airports and so on. By using this system, it offers realtime display of the monitoring scene and video playback. Besides that, more comprehensive and specific monitoring with no limit of the line-of-sight can be achieved. In this paper, a study of video surveillance system which focusing on using wireless sensor network has been done.
Various types of sensors, such as an ultrasonic sensor, a laser scanner, a microwave radar, heat and optical sensors and different kind of cameras, have been used to detect pedestrians. Algorithm used for segmentation consisting of shape based techniques, thresholding based on the brightness of the pedestrian, and a edge based techniques etc. Selecting a more efficient segmentation algorithm is important because it reduces the number of blocks that are passed to the next stage for detection, also reduce the
Most likely, they are admitted to a nursing home or hospital, but this is not the permanent solution for them and also an expensive way. In that case, wearable technology is playing an important role to solve this particular problem. It continuously monitors the physical activities of elder people which minimizes the risk of illness and injuries. With the help of wearable devices, they can observe their own health activities and measure, blood pressure, heart rate, calories burned etc. (Chan et al.
Accessible Technology Accessibility in technology is, broadly, having technology be accessible to all people, regardless of physical and/or mental disability. Accessibility to technology is vital to the well-being and quality of life of those who are disabled. According to the World Health Organization, more than a billion people (around 15%) around the world have some form of a disability (“Disability and Health”). Major types of technology that are currently in use to help people with disabilities include: closed captioning, text-to-audio readers, cochlear implants, wheelchair technology, eye tracking software, and miscellaneous other technology (“Disability and Health”). All types of technology are vital to the well-being and quality of life of those who are disabled.
The wireless sensor equipment is often used in healthcare applications while applying many types of portable sensors. These wearable sensors are placed on the patient body surface. They are composed of small devices like heart rate, blood pressure, thermometer, glucose sensors to measure the biophysical patient state, as illustrated in Figure 1.1. Hospital Doctors can ask about a patient's history by an application on the devices that communicate with the patient's wearable sensor network. The deployed Sensor network on the patient body surface consists of several components like thermometer for measuring body temperature, an ECG monitor and an activity recognition system that uses accelerometers.
Electronic senses to touch us all Dr. S. S. Verma, Department of Physics, S.L.I.E.T., Longowal, Distt.-Sangrur (Punjab)-148106. Development and use of electronic devices from day to day life activities of human to its industrial & business applications have already revolutionized our world. Besides, electronic devices/sensors are being developed to work at par with the functions of human sense organs. Human has in general five sense qualities like touch, taste, smell, hear, vision and the whole actions of human body are controlled on the basis of electric signals through their respective body parts as: skin, tongue, nose, ear and eye. Electronic development has progressed well to replicate these sense functions with electronic devices/sensors called: e-skin, e-tongue, e-nose, hearing aids and electronic-eye.
Sensors are the input devices of the robots which provide information about the external environment that what is happening and act accordingly. This information might be any color, quantity of light, distance of an object or it can be temperature etc. There are also different types of sensors like light sensor, IR sensor and Temperature sensor etc. which are used depending on the type of information. Motors are the output devices in the robots which let the robot move according to the program encoded.
Today, patients are all using medical technology in their daily life such as blood pressure machine, heart rating machine, thermometer and weighing machines. These equipment help in analysing the whole scenario and patient gets an early call towards his/her health. These technological instruments also help the Hospital staff to take action towards the problem which patient is having. May be in few cases these instruments are not able to save the life of the patient. Sometimes it happens that even the skilled nurses and doctors are not able to do their
