BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the 15 information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Now a days neural diseases affecting a large portion of the elderly population across the globe. It mainly affects a cognitive functions and memory. 20 Alzheimer disease is considered a more specific form of neural disease as it mainly affects the memory of the individual. Memory loss or forgetfulness is only few of the many symptoms that indicate the onset of neural disease.
[0004] A potential cause of injury to elderly individuals is the increased risk of 25 falling. Falls at such an age cause fractures which can eventually to rapid degradation of health and even death in some cases. The risk increases drastically when the elderly suffers from neural disease. An elderly individual who is suffering from neural diseases is most likely be under the care of family or a home nurse in case that the individual is at their own residence. Elderly individuals suffering from 30
3
neural diseases are usually disoriented and confused when left alone. Neural diseases are irreversible, progressive brain disease that slowly destroys memory and thinking skills, eventually even the ability to carry out simple daily tasks.

[0026] The communication module (104) sends an alert to electronic devices (200) linked to the device (100). The communication module (104) is connected to the controller (107). The communication module (104) is allowed to send the alert(s) to the electronic devices (200) by the controller (107) based on the inputs received to the controller (107). 10
[0027] A well-known communication module is a Global System for Mobile Communications (GSM). Moreover, the alert includes a text message, an audio message, a video message, a live location, an email and a call. More particularly, the electronic devices (200) are a mobile phone, a laptop, a computer, a tablet, an 15 artificial intelligence based electronic device and a personal digital assistant.
[0028] The input module (105) receives inputs from the patient. The input module (105) allows the user to pair the device (100) with a pill box (300). The input module (105) is connected to the controller (107). When an input is given to 20 the controller (107) using the input module, the controller (107) tries to pair the device (100) with a pill box (300).
[0029] The input module (105) may include a button, a touch screen, a switch, a mechanical switch, an electromechanical switch and a magnetic switch and an 25 electromagnetic switch. More specifically, the input may include an electric single, an electro-magnetic single, a magnetic actuation and a mechanical actuation or a virtual command.

[0033] The timer circuit (110) include a digital or an analog clock for measuring time. The timer circuit (110) enables the buzzer (111) to generate an alarm when reaches to a predefined time limit. The buzzer (111) reminds the patient the time to 25 take pills (medicines).
[0034] The controller (107) receives the heart rate from the heartbeat sensor (101). When the measured heart rate is not in range of a threshold value of the heart rate, the controller (107) generates the alert for sending to the electronic devices 30
14
(200) through the communication module (104). Similarly, the controller (107) receives the live location from the navigation module (103). When the patient’s location is changed from a predefined location to a new location, the controller (107) generates the alert for sending to the electronic devices (200) through the communication module (104). 5
[0035] Further, the controller (107) is integrated with a memory unit (108). The memory unit (108) stores an information received from the electronic devices (200).

The electronic devices (200) are linked with the device (100). The device (100) pairs with the pill box (300) upon receiving the input to find the pill box (300). The timer circuit (110) enables the buzzer (111) to generate the alarm when 5 the timer circuit (110) reaches the predefined time limit. When the measured heart rate is not in range of a threshold value of the heart rate, the controller (107) generates the alert for sending to the electronic devices (200) through the communication module (104). Similarly, when the patient’s location is changed from the predefined location to the new location, the controller (107) generates the 10 alert for sending to the electronic devices (200) through the communication module (104).
[0038] Referring now to the figure 4, the device (100) further includes a fastening member (112). The fastening member (112) allows the patient or the care 15 taker to fasten the device (100) around a body part of the patient. The present device (100) is preferred to fasten around a hand.

The controller (107) sends the images or videos to the electronic devices (200) through the 25 communication module (104).
[0040] In one more alternative embodiment of the present invention, the device (100) is provided with a temperature sensor and a sweat sensor. The temperature sensor measures the temperature of patient’s body. The well-known temperature 30
16
sensors are thermocouples, thermistors, resistance-based temperature sensors. The sweat sensor measures the sweat rate from the patient’s body. The temperature sensor and sweat sensor are connected to the controller (107). If the temperature and the sweat rate are not in range of a threshold value, the controller (107) sends the alert to the electronic devices (200) through the communication module (106). 5
[0041] As an advancement, the device (100) is capable of reminding the patient about functionality of the device (100) on the body of the patient if the patient forgets the same. If in case, the patient forgets about functionality of the device (100) on the body and throws the device (100) away from the body. The controller 10 (107) is stopped from receiving the heart rate from the heartbeat sensor (101). When the measured heart rate is zero, the controller (107) activates the speaker (106) and generates the alert for sending to the electronic devices (200) through the communication module (104). The speaker (106) helps the patient in reminding functionality of the device (100) on the body by playing the same instruction in 15 form of sound waves. The electronic devices (200) notify the caretaker and closed ones as a case of emergency.
[0042] The present invention has an advantage of providing the IOT based wearable device (100) and the system (400) for assisting neurologically affected 20 patients by alerting caretakers and closed ones in case of emergency of any sort and by notifying the caretakers if any sharply change in heartbeat.
