SYSTEM/METHOD TO CREATE AND VALIDATE SMART BLIND STICK USING ARDUIUNO

Abstract

At the moment, there are thousands of blind people living in different parts of the world. These individuals range from having a limited ability to see to having a full lack of vision. When it comes to crossing the street or getting to their destination with the assistance of another person, they have a highly difficult time doing either of these things. It is not possible for the standard stick to assist in identifying the obstructions in front of you or the potholes that are in the path. It is no longer relevant. As a result, it is necessary to bring it up to date by utilizing the technology that is available today. The smart stick for the blind is a device that, as its name suggests, is designed to assist visually impaired individuals in navigating their way to their desired destination while avoiding bumping into any obstacles that may be in their path. Ultrasonic sensors HC SR 04 are utilized in order to determine the depth below or the barriers that are there in between. Additionally, Arduino is utilized as the primary controller for this device. In addition to that, there is a water sensor that is able to detect the presence of water on the driveway or walkway. When there is any kind of obstruction in front of you An ultrasonic sensor will determine the distance from the obstruction, and a water sensor will determine whether or not there is water there and then relay that information to the controller. Afterwards, the controller will convert the data into an aural format (buzzer). 5 Claims & 1 Figure

In the (US2021/10960225B2), patent classification also includes devices, systems, and methods for treating dementia or Alzheimer's disease in a subject in need of such treatment. In one example, the subject receives persistent visual stimuli in a non-invasive manner, ranging from about 30 Hz to about 50 Hz, and specifically about 40 Hz, to entrain gamma oscillations in various parts of their brain. These regions include the prefrontal cortex (PFC) and the hippocampus. The entrained gamma oscillations modulate neuronal activity across multiple regions of the brain (for example, they facilitate the functional binding of neural networks at low gamma frequencies). This allows for the induction of a variety of neuroprotective effects (for example, the amelioration of amyloid plaques and tau hyperphosphorylation), as well as the reduction of neurodegeneration. Chronic visual stimuli, through neuronal activity, reduces an immunological response in microglia. Additionally, this activity ameliorates aberrantly changed genes and proteins involved in membrane trafficking, intracellular transport, synaptic function, neuroinflammation, and DNA damage response. This activity alters various behaviors, including improved learning and memory.

Detailed Description of the Invention
The World Health Organization estimates that there are 30 million social classes that are permanently impaired whereas there are 285 billion social classes who have vision weakness. If you spot them, you might think that they are unable to get what they require without the assistance of other people. A person is required to make a request in order to arrive at their desired destination. The ultrasonic sensor is employed to differentiate the thing that is located in front of the individual by determining the distance that exists between the stick and the item. People with disabilities that are visible to the naked eye are the smallest detail with clear eyes.

People who are visually impaired have a tough time interacting with others and feeling their surroundings. It is difficult for them to interact with their surroundings. Individuals who are visually impaired face difficulties in moving around physically due to the fact that it can be difficult for them to differentiate between the various obstacles that appear in front of them, and they are unable to travel from one location to another. The operation of these devices is quite similar to that of radar systems, which make use of ultrasonic fascicles or sonar to identify obstacles, both stationary and moving. In order to record information regarding the existence of obstacles on a road, ultrasonic sensors can be utilized.
These guidelines have a number of important shortcomings, the most essential of which are the following: fundamental abilities and the preparation stage, the breadth of movement, and extremely irrelevant information that has been transmitted. Through our methods, this stick was altered. Such problems are intended to be addressed by the electronic aiding gadgets, which are equipped with certain segments and sensors at their disposal. For the purpose of gathering information regarding the presence of obstacles in the surrounding area, ultrasonic sensors and water sensors are utilized. The ultrasonic sensor is able to identify any type of deterrent used.
