Wireless power transfer (WPT) via magnetic resonance coupling is considered a promising outlet for electric vehicle (EV) charging due to the noncontact method. Unlike a traditional transformer, with WPT, the relative spacing and lateral distance between the primary and secondary coils are highly variable, which can affect the wireless power delivery and lower the efficiency. A magnetic positioning...
In this paper, we present the “Adventure-I” mini-AUV prototype developed for educational and research tasks. The mini-AUV is simply equipped with one main propeller and two rudders, without any vertical and lateral thrusters. First, the whole structure and the main dimension of the “Adventure-I” mini-AUV is described. Second, the detailed specifications of the hardware system are illustrated, including...
Data acquisition systems used as Internet of Things (IoT) devices are generally developed for applications such as renewable energy, vehicles, or biological data collection. Methodology adapted from IoT can be used in numerous applications including sensors for underwater vehicles. Autonomous Underwater Vehicles (AUV) have become more prevalent for military use. Coincidentally, modular sensor attachments...
This paper presents a conceptual design and field test validation of a network of surface nodes providing a communication bridge between underwater sensors and Unmanned Vehicles (UV). Here we describe the combined operations of custom made low-cost buoys and Unmanned Aerial Vehicles (UAV), linked together within one network. Buoys equipped with an underwater acoustic telemetry receiver and water parameter...
In this paper, we develop the base-station platform for in-vehicle wireless sensor network system. The base-station platform is a component of in-vehicle wireless sensor network system which includes wireless sensor nodes platforms, an OBD (On-Board Diagnostics) module, and a user device (e.g., smart-phone, head-unit, and navigation). The in-vehicle wireless sensor network system applies wireless...
Overtaking traffic on undivided roadways is one of the major causes of accidents that results in fatalities and severe injuries. This is especially true in developing countries such as India, where roads are narrow, yet traffic is heavy and fast. The primary cause of such accidents is the inability of drivers to gauge the speed and distance of oncoming traffic as well as the impairment of vision due...
Using vehicles as sensors for traffic and environment monitoring is a new paradigm that opens the way to worthwhile applications. Data collected on board are usually delivered through the cellular network, with the consequent overloading risk. This paper focuses on the alternative adoption of short range vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) communications, with particular reference...
The internet of things (IoT) is a network to realize interconnects between almost any object and web services. It can be applied in many domains, such as radio frequency identification (RFID), wireless sensor network(WSN) and so on. The application of IoT brings us the higher efficiency and the more convenient life. In this paper, we propose a new IoT application framework to search the optimal routes...
The paper presents the implementation of wireless sensor system to California launch vehicle education initiative (CALVEIN) program. The CALVEIN program provides student the opportunity to build, design, and flight test low cost launch vehicles for education and technology development purposes. This enables the researchers to rapidly test new wireless aerospace technologies, which can be used in the...
This paper presents an overview of self-contained automated video analytics units that are man-portable and constitute nodes of a large-scale distributed sensor network. The paper highlights issues with traditional video surveillance systems in volatile environments such as a battle field and provides solutions to them in the form of Rapidly Deployable Video Analysis sensors. We discuss scientific...
We introduce integrated parking management system (IPMS) based on wireless sensor network. The system was designed with the object of a large scale deployment in existing facilities, and has been actually deployed to monitor over 400 parking spaces. This paper describes the fundamentals of hardware and software design, and several efforts to facilitate a long-term operation and ease of management...
Vehicle access control system is an important sub-system of the intelligentized residence section. Today, in a growing emphasis on personal and property safety, the control of vehicles' access authorization and the management of the vehicles' access authority, access time and access method via computer, is safe and convenient. This paper describes a set of vehicle access control system based on ZigBee...
This paper presents the Inter-Module Communication (IMC) protocol, a message-oriented protocol designed and implemented in the Underwater Systems and Technology Laboratory (LSTS) to build interconnected systems of vehicles, sensors and human operators that are able to pursue common goals cooperatively by exchanging real-time information about the environment and updated objectives. IMC abstracts hardware...
Teams of autonomous cooperating vehicles are well-suited for meeting the challenges associated with mobile marine sensor networks. Swarms built using a physicomimetics approach exhibit predictable behavior - an important benefit for extended duration deployments of autonomous ocean platforms. By using a decentralized control framework, we minimize energy consumption via short-range communication and...
Wireless sensor nodes capable of vehicle speed measurement can replace traditional speed measurement systems such as dual loop detectors. We designed a wireless sensor node for vehicle velocity measurement using two magnetic sensors. We present the sensor node architecture, velocity measurement methods, algorithms, and propose an implementation method for the SAD algorithm for which a hardware accelerator...
