This technology aims at developing an unobtrusive and minimally invasive assistive technology for people with severe disabilities.Tongue controlled technology detects the user’s voluntary tongue movement and translates it into user defined commands. Since the tongue is connected to the hypoglossal cranial nerve, it escapes damage in most spinal cord injuries. Hence it can be used to drive the assistive technology. This technology uses Hall Effect sensors fixed on a head mounted device for detecting the proximity of a permanent magnet which is placed on the tongue. When the sensor senses the magnetic field generated by the magnet, it sends an output signal to the micro-controller which acts as an interface between the sensors and the PC. A Visual Basic ...

Description of "Personal Viewer Eyewear Display":

The Personal Viewer is an eyewear display (i.e. worn on the face like sunglasses) that presents its user with an ultra-wide field of view and has a low profile on the user's face and has very low weight. Additionally, the display does not block the users' view of their surroundings in any way.

Applications

There are many eyewear display applications that will benefit greatly from provision of a full breadth of human visual field, which is approximately 180 degrees horizontally and 100 degrees vertically (see Figure xx1). These include gaming, telepresence, training, augmented reality and cinema. Gamers are generally displeased that they cannot see to the sides of their current ...

When you’re walking in the hallways, have you ever imagined building an extra cool device, which would enable you to navigate large objects without sight?

Well, let’s meet the ULTRASONIC HAPTIC VISION SYSTEM. It uses an ultrasonic rangefinder that interfaces with the user via tiny vibrating motors and allows the user to wear it on their head.

The main goal of this project is to develop a sixth sensory system that can easily interact with the body in an intuitive way, while keeping the user friendly fashion in the same time. The best part about this device is the user can navigate with the device without using their vision at all!

The rangefinder is rotated by ...

The electric eel generates large electric currents by way of a highly specialized nervous system that has the capacity to synchronize the activity of disc-shaped, electricity-producing cells packed into a specialized electric organ. The nervous system does this through a command nucleus that decides when the electric organ will fire. When the command is given, a complex array of nerves makes sure that the thousands of cells activate at once, no matter how far they are from the command nucleus. The electric eel has three abdominal pairs of organs that produce electricity: the Main organ, the Hunter’s and the Sachs organ. These organs comprise four fifths of its body.

These organs are made of electrocytes, lined up so that ...

The growth of technology is witnessed every day and everywhere. From rural to urban areas we have technological innovations working and growing. There are medical experts in cities who treat and diagnose diseased people. But people in urban areas do not stand a chance to get treated by medical experts, because the medical experts hesitate to travel to villages and treat the people there.

In order to reduce the human effort in treating and diagnosing of diseases, a virtual environment called V-Doctor is created which checks for diseases and prescribes medicines accordingly. The main aim of the project is to offer medical services to people in urban areas across the country at free of cost. The process is that, ...

Often in our life we come across people with upper limb amputation. They face many troubles in performing chores of their daily life. The present assistive techniques available in the market are either only for cosmetic purpose or mechanical that is bulky and is highly expensive. Our goal is to provide a prosthesis that is easily operable through voice inputs, light-weight and uses wireless communication.

The assistive hand is controlled by a microcontroller unit and used with the help of an android app. Initially the Bluetooth is activated in the phone. By switching on the power supply the Bluetooth module on the assistive hand also gets activated. When the instructions are given by the person, the voice ...

Background :
When an emergency braking situation occurs, people panic to control the vehicle to avoid the accident. But unlikely we should not be able to control the vehicle (refer Fig 1 to 5 without wind catcher). Why? Because all our primary, secondary, parking brake system depends upon surface contact between tyer and road. Even ABS/ESP can’t prevent the above situation. We have air bags to save us from an accident, but don’t have any emergency brake system to keep away from accident.

Panic braking causes mass transfer from rear to front, means people in the vehicle pushed towards front, this may cause some injury/pain leads to death (mostly driver/front seat passenger). Preventing the vehicle lifting is also important.

Short Message Service (SMS) has become a user friendly way of communication between people because of its ability to convey information when unable to make a voice call. In this paper, we have explained on how messaging can be done between two landlines similar to mobile phones by attaching a display along with the phone set which was also demonstrated as a project. This concept is also applicable to make messaging between landline and mobile phone and vice-versa. This application comes handy to people without mobile phones as SMS can be done using landlines which still dominate the telecommunication industry and hence proves to be a beneficial gadget.

It requires readily available electronic components like a microcontroller, ...

Today everywhere in the world use of mobile is increasing day by day because communication anywhere in the world is possible only in few seconds. In early days mobiles was used for calling and sending messages but now a mobile phone can do anything which a laptop or computer do. But there is still one problem which a mobile is facing is battery discharging, more the number of apps early the battery will discharge and it is difficult to put mobile on charging every time due to the wire.

In this idea we are charging our mobile phone without wire, here we are plugin our mobile adapter in the supply board and the power from the board will transmitted ...

The technology developed is a monitoring system that includes a base station and at least one sensor unit mounted some distance away, which is in wireless, one-way communication with the base station. The sensor lies dormant until it receives a voltage trigger from a vibration-sensitive switch which consumes no stored power from the battery. When activated, the sensor takes a measurement, transmits the data to the base station, and then returns to its dormant state. The measurement taken is recorded and time stamped. The system can be utilized in commercial applications that require long term monitoring of events associated with different types of strain, cryogenic temperatures, ambient temperatures, limit switches, 4-20 milliamp signals, 0-10 volt signals and magnetic fields. ...
