Recently, integration of different radionavigation systems has become very popular, since it improves system integrity, availability, accuracy and reliability. This paper discusses a new, flexible and cost-effective approach to system integration, centred on a single-chip application specific processor (ASP). An overview of this integrated system is presented and the application of the ASP for the implementation of a six-channel GPS, OMEGA, Loran-C and MLS receiver is given. The ASP is currently being implemented on a 180000 transistor 1·6μ, m CMOS Sea of Gates chip, and is expected to run at 100 MHz clock speed.

Gradual Development

With the gradual development of economy, the scale of transportation industry continues to expand. The problem of overload or overrun in the vehicle transport has emerged. Therefore, how simply and conveniently to know the vehicle load and how to effectively limit overload has become a key issue. This paper demonstrates the feasibility of vehicle load control system from the above problems. Through the pressure sensors installed in the vehicle suspension, the single-chip microprocessor receives the information transmitted by the pressure sensors, and calculates the total weight of the vehicle load; if overweight, the single-chip microprocessor will send commands to the ignition system, to stop the ignition system working. Its purpose is to improve vehicle safety and effectively reduce heavy workload of the vehicle detection station to improve their work efficiency.

Wide Range

The development of renewable energy, especially solar, is essential for meeting future energy demands. The use of a wide range of the solar spectrum through the solar cells will increase electricity generation and thereby improve energy supply. However, solar photovoltaics (PV) can only convert a portion of the spectrum into electricity. Excess solar radiation is wasted by heat, which decreases solar PV cells’ efficiency and decreases their life span. Interestingly, thermoelectric generators (TEGs) are bidirectional devices that act as heat engines, converting the excess heat into electrical energy through thermoelectric effects through when integrated with a PV. These generators also enhance device efficiency and reduce the amount of heat that solar cells dissipate. Several experiments have been carried out to improve the hybrid PV-TEG system efficiency, and some are still underway. In the present study, the photovoltaic and thermoelectric theories are reviewed. Furthermore, different hybrid system integration methods and experimental and numerical investigations in improving the efficiency of PV-TEG hybrid systems are also discussed. This paper also assesses the effect of critical parameters of PV-TEG performance and highlights possible future research topics to enhancing the literature on photovoltaic-thermoelectric generator systems.

This paper introduces the conceptual system design of micro-hydro/solar hybrid system for Kampung Semulong Ulu, Sri Aman, Sarawak. Currently, Kampung Semulong Ulu is powered by solar and diesel-generator energy systems. The existing solar system generates less than 160 W for each door of the longhouse. With the completion of micro-hydro system along with the existing solar panel in the village, the community is hoping to get the proper and continuous power generation. Community in Kampung Semulong Ulu is facing difficulties since solar is only available for a limited period and yield electricity within a limited range of load. On the other hand, the running cost of diesel-generator is very expensive and unaffordable. However, even with the existence of power generated by micro-hydro system, better utilization of the energy produced is still of vital importance due to the fact that the amount of energy generated is limited. Therefore, the conceptual system design of the hydro-solar system integration is presented. The proposed system is to ensure that the energy produced will be well-distributed and at the same time, both systems must be utilized sufficiently to ensure their sustainability. In overall, this paper presents the micro-hydro/solar hybrid system framework for off-grid application toward the community in Kampung Semulong Ulu.

Two Alternatives

The main goals for developing hybrid power train system are reducing emissions and providing commercially viable low cost transportation solutions. To achieve these goals, a well defined set of targets and specifications are necessary for the hybrid system development. These targets and specifications are needed for design, analysis, and validation of the power train subsystems, components, and successful system integration. During hybrid system design and development, there are many alternatives and design configurations to choose from. To select the most efficient systems duty cycle data and profiles are needed to assist in defining the design targets and specifications. For buses, due to their well defined routes the duty cycles can be achieved through data acquisitions or by using the American Public Transit Association (APTA) standard duty cycle. In this paper, the APTA duty cycle profiles are used to evaluate two alternatives power train configurations for a bus series hybrid system. The first configuration consists of two electric motors and one speed transmission while the second configuration consists of one electric motor with two speed transmission. The simulation and analysis results of both configurations are presented.
