Walking Stick

Visually challenged people (VCPs) face many difficulties in their routine life. Usually, in many cases, they need to depend upon others, which makes them unconfident in an unfamiliar environment. Thus, in this paper, we present an aid that helps in detecting obstacles and water puddles in their way. This system comprises a walking stick and Android-based applications (APPs). The walking stick is embedded with Raspberry Pi and programmable interface controller (PIC) as a control kernel, sensors, a global position system (GPS) module, and alert-providing components. Sensors help to detect obstacles, and the VCP is informed through vibrations or a buzzer according to the obstacle detected. The GPS module receives the coordinates of the VCP’s location, and the location can be tracked by parents using an APP. Another important APP is used, called an emergency APP, by which the VCP can communicate with parents or friends immediately by just shaking his/her cell phone or pushing the power button four times in 5 s in panic situations. We used fewer components to make the device simple, lighter, and cozy with very good features. This device will help VCPs to live an independent life up to some extent (with security), which ultimately will increase their confidence level in an unknown environment.

Dead In Bed Syndrome

Intensive insulin therapy has an inherent risk of hypoglycemia that can lead to loss of consciousness, cardiac arrhythmia, seizure, and death (“dead-in-bed syndrome”). This risk of hypoglycemia is a major concern for patients, families, and physicians. The need for an automated system that can alert in the event of severe hypoglycemia is evident. In engineering systems, where there is a risk of malfunction of the primary control system, alert and safety mechanisms are implemented in layers of protection. This concept has been adopted in the proposed system that integrates a hypoglycemia prediction algorithm with a global position system (GPS) locator and short message service such that the current glucose value with the rate of change (ROC) and the location of the subject can be communicated to a predefined list. Furthermore, if the system is linked to the insulin pump, it can suspend the pump or decrease the basal insulin infusion rate to prevent the pending event. The system was evaluated on clinical datasets of glucose tracings from the DexCom Seven® system. Glucose tracings were analyzed for hypoglycemia events and then a text message was broadcast to a predefined list of people who were notified with the glucose value, ROC, GPS coordinates, and a Google map of the location. In addition to providing a safety layer to a future artificial pancreas, this system also can be easily implemented in current continuous glucose monitors to help provide information and alerts to people with diabetes.

Kemajuan teknologi informasi telah mempengaruhi berbagai bidang kehidupan, tidak terkecuali bidang bisnis pariwisata. Salah satunya adalah digunakannya teknologi internet sebagai media informasi. Tujuan dari penelitian ini adalah memberikan masukan kepada pelaku bisnis tour and travel akan manfaat pengembangan arsitektur bisnis dalam usaha kepariwisataan agar perusahaan dapat berperan serta memajukan pembangunan nasional khususnya dalam usaha kepariwisataan. Enterprise arcitecture planning menurut Spewak ini pemodelan sistemnya menggunakan Unified Modeling Language (UML) dan menggunakan software bahasa pemrograman PHP dan menggunakan database MySQL untuk penanganan database. Hasil dari program perancangan ini adalah berupa aplikasi berbasis web yang menyediakan informasi mengenai destinasi wisata, rute perjalanan wisata yang dapat ditempuh, serta fasilitas transportasi dan akomodasi yang tersedia. Diharapkan aplikasi ini dapat menjadi salah satu website kepariwisataan yang dapat dimanfaatkan juga oleh pemandu wisata. Penyediaan informasi kepariwisataan berbasis web selain akan memudahkan wisatawan dalam  mengenal dan merencanakan perjalanan wisata, juga menunjang pengembangan database sektor kepariwisataan di Indonesia. Diharapkan wisatawan dapat memanfaatkan aplikasi Maps API  juga Global Position System untuk memperoleh informasi kepariwisataan yang dibutuhkan.

This paper presents the design and implementation of control strategy for both the speed and direction of a direct current (DC) motor using Android-based application in smart phone. The Raspberry Pi 3 with a motor driver controller has been used to implement the control action via Python-based user-defined programming. The Android application has been developed using Android Developer Tools (ADT) in Java platform. The Android apps work like a client and communicates with Raspberry Pi through wi-fi connectivity. Finally, a small graphical user interface (GUI) has been created in Python in order to interface and control the motor with buttons in GUI. The advantages of GUI are that it is attractive, user friendly, and even a layman can work with the application developed in GUI.

Smart static and dynamic obstacle walking stick with EMF detector is an upgraded smart stick designed for blind people for optimal navigation and electrical safety.  An advanced blind stick prototype that allows visually challenged people to navigate walking paths and identify electronic gadgets with ease using modern technologies is hereby developed. The blind stick is integrated with ultrasonic sensor along with an EMF detector. This prototype first uses ultrasonic sensors to sense obstacles ahead using ultrasonic waves. On sensing obstacles, the sensor directs this data to the microcontroller. The microcontroller then processes this data and examine if the obstacle is close enough. If the obstacle is not that close the circuit does nothing. If the obstacle is close the microcontroller sends a signal to sound a buzzer. One more feature is that it allows the blind to detect the presence of EMF (electromagnetic field/electromagnetic waves) in the region he/she is, if there is, the microcontroller also sends a signal to a vibration motor (i.e. the output is in form of vibration), and if otherwise, the circuit does not trigger and thus, the vibration motor does nothing. The results obtained from the measurements have shown that this project work is optimally working and indeed operative.
