The axial C4D (Capacitively Coupled Contactless Conductivity Detection) measurement electronics for capillary electrophoresis is considered and a new improved C5D compensated detection concept is proposed and tested. Using the idle compensation channel with inversed signal and immediate analogue summation of the active and idle channel currents yields effective suppression of the influence of the parasitic stray capacitance. Preliminary experiments have confirmed at least threefold improvements of measurement resolution. Realisation of electronics allows flexible tuning of frequency from 0.2 MHz to 2 MHz. The relatively high voltage supply of 15 V for the AC measurement units together with 24bit accurate analogue-to-digital converter yields additional improvement for the sensitivity.

<span lang="EN-US">Traffic jam that is resulted from the buildup of vehicles on the road has become an important problem, which leads to an interference with drivers. The impacts it has on cost and time effectiveness may take the form of increased fuel consumption, traffic emissions, and noise. This paper offers a solution by creating a smart traffic light using a fuzzy-logic-based microcontroller for a greater adaptability of the traffic light to the dynamics of the vehicles that are to cross the intersection. The ATMega2560 microcontroller-based smart traffic light is designed to create a breakthrough in the breakdown of congestions at road junctions, thereby optimizing the real-time happenings in the road. Ultrasonic, infrared, and light sensors are used in this smart traffic light, resulting in the smart traffic light’s effectiveness in parsing jams. The four sets of sensors that are placed in four sections determine the traffic light timing process. When the length of vehicle queue reaches the sensor, a signal is sent as the microcontroller’s digital input. Ultrasonic and infrared sensors can reduce congestions at traffic lights by giving a green light time when one or all of the sensors are active so that the vehicle congestions can be relieved.</span>

“…As it can be seen in this table, UCOADP module has the converter with the highest resolution and it is the only one which includes a PGA. Although the resolution of the converters embedded in the microcontroller can be increased using additional external electronics [27], this would increase the complexity of the system and the consumption.…”

In this work, a low power datalogger with a wireless connection is described. The datalogger can be used as a portable and stand-alone device, as well as a wireless sensor network node. A flexible architecture, which combines a microcontroller with external local buses (data and address) and a complex programmable logic device (CPLD), has been used. The system has two special characteristics: one of them is the high resolution of A/D converters; the second is based on the incorporation of a non-volatile random-access memory (NVRAM) that allows fast access to stored data and a low consumption. Storing data in an NVRAM implies an extra security level for the maintenance of data even when the batteries of the system have been exhausted. The complete glue logic has been integrated into a Zero-Power CPLD in order to reduce size. In addition, in each specific application, the CPLD allows the implementation through hardware of some interfaces to sensor module, saving computation time.
