Embedded systems’ hardware can be impacted by soft errors, which causes either a data flow error or a control flow error in the systems’ software. To counter such errors, numerous software-implemented techniques have been proposed to detect either one of them. However, there exist few techniques that are designed to detect both types of errors. This paper aims to fill that gap by proposing a software-implemented technique that has been designed to detect both data flow and control flow errors, called Data and Control Flow Error Detection (DCFED). We verified the technique using a fault injection campaign and compared the measured results to those of a similar technique, called Software Implemented Error Detection (SIED). The results show that DCFED achieves a higher error detection ratio.

The current report proposes a non-contact and non-destructive method for characterisation of cosmetic foams. The method is based on using ultrasonic emitter and receiver which detect the reflected signals from the irradiated object. The results were processed by spectral analysis of signals method - Discrete Wavelet Transform (DWT) of Haar implemented with fast conversion.

The Voltage Controlled Oscillator is replaced by Digitally Controlled Oscillator in the digital Phase Locked Loop systems. The Digitally Controlled Oscillator has several differences and limitations which require further study in order to compare the different circuit variations and to choose the most appropriate circuit for the application. The frequency range, frequency step and the frequency change delay are examined in this paper. The results from the testing of the different circuit variations are compared and represented in graphical form. The useful range of working frequencies is discussed.

In this paper we present and demonstrate a cost-effective alternative of infrared cameras - wireless sensor device that can be applied in the field of AAL, health care and security smart systems in home environment. It is designed as an IoT solution and it employs a new infrared array sensor MLX90640. For this purpose a Wi-Fi open source hardware board is used both for gathering the data from the sensor, processing the data and presenting it to Internet connected devices. The paper demonstrates the benefits of using relatively inexpensive sensor and open source hardware board for developing a solution with multiple applications and flexible connection to other smart devices via web interface.

In this paper the use of Adaptive Frequency Hopping (AFH) as a solution to interference problems caused by the proximity and simultaneous operation of radio systems in the 2.4 GHz band is discussed. The main algorithms for AFH that attempt to avoid frequency collisions are considered. A comparative analysis of their respective performance is conducted. The trends and trade-offs for different interference levels are discussed. Performance is analyzed in terms of collision frequency and channel usage distribution frequency.

Incontinence is a very common condition among nursing home residents. This not only leads to physical and mental burden for the elderly residents, but also to an increased workload for care personnel. In order to lower this imposed workload, numerous technologies exist to support incontinence care. These systems, however, are expensive for the nursing homes and inconvenient for the residents. To solve these problems, we propose a new sensor system now attached to the bed that is able to monitor and detect incontinence events. Using Bluetooth Low Energy and the time-based database InfluxDB a prototype was built. The sensor data can be stored in real-time and can be made available to other systems for further processing. In future systems, security measures can be added, and energy measurements can be done to make the system fully portable.
