“…Fundamentally, the time-triggered approach depends on the timer interrupts, thus, this approach can be imposed into or integrated with other time-triggered systems such as TMO [3]. The TMO uses clock interrupts for scheduling and dispatching the processor to SpM's and SvM's in TMO objects.…”

Abstract.Recently, the battery and low-power H/W technologies for mobile and wearable computing devices have been advanced rapidly. But on the other hand the computation and communication demands of the embedded applications are increasing more rapidly. Therefore, the application developers are still required to develop their codes to utilize the available energy as efficient as possible. The provision of software power measurement with reasonable accuracy, consistency and low overhead is an indispensable factor for software power engineering. In this paper, we present a time-triggered mechanism for providing energy consumption profiles in the level of C functions. The similar mechanisms have already been introduced at the previous researches such as PowerScope and ePRO. Instead, we, in this paper, introduce our efforts to extend these researches to incorporate power domains and DVS(Dynamic Voltage Scaling), then interpret these mechanisms as the view of time-triggered approach for better understanding to the relationships among timer interrupt, context switching, DAQ triggering, multi-channel DAQ delay, and etc. From our experimental results, we could conclude that the timetriggered approach for the function level energy measurement properly worked with low overheads and produced consistent energy consumption profiles on the DVS-applied program codes running upon the platforms supporting multiple power domains.

“…The section 4 will present our experimental results with our interpretation in the view of consistency and overhead. The section 4 will conclude this paper with suggestions for further research directions such as imposing our efforts into other time-triggered engines like TMO (Time-triggered and Messagetriggered Object) [3].…”

“…The system consists of related services such as location tracking service, healthcare information and supporting service. To facilitate information collection and sharing in this environment, we adopted the TMO scheme and TMOSM [5] into the development environment of the system that we implemented. The architecture of the system is shown in Figure 1 and is organized in five layers.…”

Abstract. The distributed object group framework (DOGF) enables easier integration of distributed objects to healthcare home applications. This paper describes a healthcare information management system for supporting healthcare home services based on DOGF. The system architecture consists of healthcare database management tool, framework, sensor manager and physical elements such as sensors, devices and appliances. The focus of this paper is on the design and construction of a database system in a framework to support home healthcare services. Healthcare information is organized using database schemes based on the specific types of data collected from various typedsensors. The database constructed from this information for the purpose of home healthcare services is divided into the base information that uses the real schemes and the context based information that uses the view schemes. To verify the practical use of the healthcare information management system proposed in this paper, we created a prototype healthcare home monitoring service using information, emergency call, and home appliance control. The result of the experimental evaluation shows the comparison of the execution service time of the base information and the context based information in our simulated scenario of a home healthcare application.

Abstract. The technologies for designing and validating computer-control systems subject to challenging timing and reliability requirements have been advancing slowly. One such type of systems are unmanned aerial vehicle (UAV) control systems. The functional complexity of UAV control systems is steadily increasing. Enabling the design of such complex systems in easily understandable forms that are amenable to rigorous analysis is a highly desirable goal. In this paper, we discuss our experimental application of the Time-triggered Message-triggered Object (TMO) structuring scheme to the design of a UAV control system. The TMO scheme enables high-level structuring together with design-time guaranteeing of accurate timings of various critical control actions with significantly smaller efforts than those required when using lower-level structuring schemes based on direct programming of threads, UDP invocations, etc. An experimental 2-step validation of a UAV control system is also discussed. The first step was to validate the system by use of an environment simulator and then real flight tests were involved only in the second step.
