This paper presents a low-cost open source prototype of a gesture recognition and interpretation glove that aids audio-vocally impaired individuals in communication. A sensor based glove for recognition of the gestures in the American Sign Language (ASL) is the input module to the system. It incorporates resistive flex sensors and contact sensors appropriately positioned to obtain a theoretical efficiency of 96% in character recognition. When the sensors are subjected to change in orientation by the user, the variation in electrical resistance of each of the individual sensors is obtained as the input to an Arduino ATMega328 microcontroller that accurately maps it to the letters of the English alphabet through an efficient algorithm. An elegant methodology that is easy to implement using a microcontroller is employed for the mapping process to minimize the complexity of the system. The paper also presents a detailed study of the efficiency characteristics involved in the construction of the custom-designed flex sensors utilized in the system. The paper outlines the calibration and testing results of the sensors .The highlights of the system are its ergonomic and economical design, portability and intelligent gesture recognition and interpretation ability. The implemented system achieves a practical efficiency of up to 80% of theoretical efficiency. The cost of the system is approximately less than USD 5 at laboratory condition using off the shelf components.
This paper details the implementation of a lowcost, open hardware, cloud-based intelligent farm automation system. Physical parameters such as soil moisture, temperature and humidity are measured by employing sensors sited across the monitored area. The parametric data is transmitted to the Atmel ATmega328P microcontroller from the sensors using Bluetooth Low Energy (BLE). The cloud performs real time intelligence operations based on periodic sensor inputs obtained from the farm and transmits control commands to the microcontroller. The novelty of the system lies in the use of BLE and in the intelligence provided by the cloud. The physically monitored, as well as virtually obtained parameters, at the cloud level allow intelligent command generation, facilitated by a data exchange system that leverages the existing telecom network prevalent in developing countries. Based on the cloud commands, the ATmega328P microcontroller controls the operation time period of the irrigation system thus conserving both water and energy. The approximate cost of implementing the proof of concept system elaborated in this paper by using off the shelf components at retail price is about USD 16. It is expected that the system cost will further reduce on mass production and commercialization.
In this paper we present a combination of technologies to provide an Energy-on-Demand (EoD) service to enable low cost innovation suitable for microgrid networks. The system is designed around the low cost and simple Rural Energy Device (RED) Box which in combination with Short Message Service (SMS) communication methodology serves as an elementary proxy for Smart meters which are typically used in urban settings. Further, customer behavior and familiarity in using such devices based on mobile experience has been incorporated into the design philosophy. Customers are incentivized to interact with the system thus providing valuable behavioral and usage data to the Utility Service Provider (USP). Data that is collected over time can be used by the USP for analytics envisioned by using remote computing services known as cloud computing service. Cloud computing allows for a sharing of computational resources at the virtual level across several networks. The customer-system interaction is facilitated by a third party Telecom Service provider (TSP). The approximate cost of the RED Box is envisaged to be under USD 10 on production scale.
Regarding development in the request and utilization of vitality. India is developing exponentially. With the request of spotless and environmentally friendly power vitality, it is important to tackle the tremendous potential from the sustainable power source part. With the GOI strategy and rules, around nine level of the aggregate introduced limit originates from the inexhaustible sources. With the expanded to the framework and observed to keep up the recurrence and members in the age administration framework. Given the vulnerability and inconstancy in the yield of generator, it is a noteworthy test to keep up the matrix with this vacillation. Under this viewpoint, this paper underscores the technique to address the difficulties in incorporating the power from sustainable power sources. Quantum of wind vitality is corresponded with the breeze speed and heading, shrewd estimate motor is embraced to lessen the uncertainly.
