In this paper we present a vanishing point algorithm variation oriented to a VLSI ASIC. We proposed a simplified voting process and analyze the minimum resolution that can be used for the input image and the filter kernels in order to obtain a good performance.
The demonstration will show ECG signal acquisition and processing on a dedicated System-on-a-Chip (SoC) [1], and display of the raw and processed data on the screen of a laptop. This SoC has been developed within the European project IcyHeart [2]. The objective of the IcyHeart project was to investigate and demonstrate a highly integrated and power-efficient microelectronic solution for remote monitoring...
This paper describes a complete low-power System-on-Chip (SoC) dedicated to Electrocardiogram (ECG) monitoring, and focus on the analog front-end sensor interface. The SoC mainly embeds a three channels ΣΔ-ADC-based sensor interface, an energy-efficient ECG signal processing and a low power radio-frequency transceiver (RF). The whole SoC was fabricated in TSMC 0.18µm General Purpose CMOS process....
Particle Filter is an algorithm that provides system state estimation even for non-linear and non-gaussian systems. For applications that require a large number of particles, real time constraint is hard to accomplish since the algorithm is computationally expensive and the resampling step becomes a bottleneck. In this work, a VLSI architecture for particle filtering in real time is presented. The...
When mining vehicle operators take risks, there is a increased probability of an accident that can cause injuries, fatalities and large financial costs to the mine operators. It can be assumed that the operators do not intentially take unnecessarily high risk, and that the risks are hidden due to factors such as adverse weather, fatigue, visual obstructions, boredom, etc. This paper examines the potential...
A fast low power time delay estimator for the localisation of impulsive sounds is shown. The system is based on a simplified Kalman filter structure and is implemented on a 0.5 m standard CMOS architecture. Tests show that the circuit is faster than equivalent systems, and that its energy requirements are lower than the best results reported so far.
The present paper reports the design and implementation of a system which purpose is the prevention of fires in forest areas. The system is based on the application of sensor networks, mobile telephony and data processing. Immediate availability of the values of different environmental variables and the application of several models, allow to assess the risk of fire in an area of interest very quickly...
An amperometric ATP microbiosensor was developed to determine the role of ATP in mediating maturation of chemosensitivity of peripheral arterial chemoreceptors at the carotid body (CB) to physiological stimuli. The carotid body regulates ventilation via the release of neurotransmitters detected by the brain. Clinical studies to determine the age-dependent release of ATP stimulated at the rat carotid...
