Lab-on-chip systems comprise a class of devices that integrate fluidics and electronics on a single chip. Lab-on-chip devices are capable of handling and analysing chemical and biological liquid samples. Microfluidic devices comprise a broader group that includes lab-on-chip devices and also micro total analysis systems (μTAS). The formers are devoted to laboratory use, such as sample testing and handling, while the latter focuses mostly on biochemical analysis down to molecular level. Lab-on-chip devices facilitate automated operations such as sample handling, separation and liquid mixing. Furthermore, lab-on-chip devices force the development of point-of-care devices, which are expected to become the leading technology for diagnosis and therapeutics in personalized medicine.

An interface for impedance spectroscopy measurements of piezo-sensors has been developed, for a digital signal processor of Delfino series of Texas Instruments. DAC of the interface is based on a 16-bit PWM with extra 8-bit part of “high resolution” (of picoseconds), with external simple (3-rd order) analog filter. Internal 12-bit ADC is converting at rates of up to 10 MS/s with 2 simultaneous sample-and-holds. So, with few extra components, high-performance analog interface has been “improvised” (developed and investigated) with a frequency range 10 kHz −400 kHz about 0,1% of the full scale resolution and repeatability of measurements.

Communication modelling and synthesis plays an important role in the design of complex network-on-chip (NoC) based timing-sensitive systems-on-chip (SoC). To guarantee timing constraints without detailed know-how of communication might lead to unexpected results. In our previous work we have proposed an approach for communication modelling and synthesis to calculate communication hard deadlines that are represented by communication delay and guide the scheduling process to take into account possible network conflicts. In this paper we combine our communication scheduling approach with global optimisation techniques to perform design space exploration and/or improvement of the synthesised schedule.

In this paper, we introduce the wind-photovoltaic hybrid power system (WPHPS) installed in Mongolia and the safety assessment for the WPHPS, which was implemented to prevent the failure mode. In order to prevent desertification and build afforestation, two groups of photovoltaic systems were installed in the Gobi desert. One of the generators, which produces 70kW of the power, operates as the power plant for cultivation in this area and another one works with wind power generator. To operate these installed systems effectively, must be implemented the safety assessment. Failure Mode and Effect Analysis (FMEA) was used as a safety assessment method in this study. The 28 of important assemblies of WPHPS were evaluated by FMEA and the results carried out 47 failure modes.

Patient remote monitoring has continuously rising importance for aging countries. Computer based assisted living systems are too difficult to handle by elderly people, therefore it has been proposed to extend smart home control or entertainment systems with patient monitoring functionalities. However, such implementations are usually platform and data protocol specific making their extension time consuming and data interpretation complicated. We propose a semantics driven messaging system and agent based software architecture for home telecare that is open for adding any kind of medical or context sensors, either wired or wireless ones. System can be reconfigured during the operation and its output data is highly compatible with eHealth databases. The solution is prototyped.

Wireless Sensor Networks (WSN) are being used in growing numbers for monitoring industrial fields, agriculture storage and environment. The building bricks of these networks are the sensor nodes, which makes the design of the nodes a very important task. During the development a trade-off between complexity, functionality, power consumption and of course time and financial aspects has to be made. In this paper we are going to present our WSN which is designed for monitoring forest fires; low cost, low power consumption and flexibility in mind. Microchip PIC18F4685 MCU, Silicon Laboratories Si4432 ISM Band transceiver are the core components of the implementation. The basic functional principles and the results of the power consumption measurement are also presented.

This paper analyzes the most significant details of development of a modern luminary. One of the effective ways to improve the energy efficiency of lighting systems and luminaries is to use the so called smart luminaries. This means that the luminaries turn on exactly at the place and time when the light is required, as well as with the required intensity of light. Such approach is especially effective if LED elements are utilized. Development of the smart LED luminaries includes several tasks: elaboration of energy efficient power supply equipped with distance controllable dimming function; choice and implementation of sensors; choice and development of communications for data exchange between luminaries, sensors and overall control system. The paper briefly describes the main problems of development of the smart lighting systems with LEDs as well as their solutions.

Timing error detection (TED) is a method in which setup timing errors are detected during run-time. When a violation is found, the system reacts on it to prevent error propagation. Incorporating TED circuits to a design introduces overhead. Thus, understanding how to efficiently implement TED with respect to the design constraints is a key issue. In this paper we compare energies of a conventional design to a TED design using different logic styles with different logic imbalances to investigate the energy difference between the designs in subthreshold operation region. TED mitigates variation problems introduced by using subthreshold operation, which is discussed. Using a 65 nm CMOS process, four different blocks have been simulated and analyzed, and subthreshold energy curves based on the forementioned are presented. The results indicate possibility for energy saving by utilizing TED.

The research concentrates on the upgrades of the inefficient diesel-electric shunting locomotive powertrains, produced in the former Soviet Union. The existing diesel-generator unit (DGU), serving as an onboard power plant can be replaced by hybrid units, with an energy storage unit acting as a peaking power source for dynamic modes. By integrating an energy storage unit into the power plant, the locomotive traction drive becomes hybridised, consuming less fuel during transients and idling. The paper presents a method for conceptualising the novel hybridised locomotive powertrain.

A general purpose input output (GPIO) interface is briefly overviewed in current paper, with the main focus on the output circuitry portion. As a result a GPIO output buffer for portable applications is proposed with up to 5mA load driving capability, an overlap protection and ability for reverse current protection in off state when output is pulled above supply rail. The buffer is able to work at frequencies up to 10MHz with a maximum supply current of 70µA.
