AbstractA method for EEG-based distraction detection during motor-rehabilitation tasks is proposed. A wireless cap guarantees very high wearability with dry electrodes and a low number of channels. Experimental validation is performed on a dataset from 17 volunteers. Different feature extractions from spatial, temporal, and frequency domain and classification strategies were evaluated. The performances of five supervised classifiers in discriminating between attention on pure movement and with distractors were compared. A k-Nearest Neighbors classifier achieved an accuracy of 92.8 ± 1.6%. In this last case, the feature extraction is based on a custom 12 pass-band Filter-Bank (FB) and the Common Spatial Pattern (CSP) algorithm. In particular, the mean Recall of classification (percentage of true positive in distraction detection) is higher than 92% and allows the therapist or an automated system to know when to stimulate the patient’s attention for enhancing the therapy effectiveness.

Good Agreement

In this paper, low pass band filter with via holes and using artificial ground structure are proposed. The design contains a u-shaped parasite element and gives via hole which is connected to the ground on the adjacent side with a copper. A hole in this design has a diameter 1 mm. The A have the form square 15mm x 17.5mm, given an effect, if compared with the non-artificial ground structure system, this addition show that the bandwidth of the low pass filter is shifting regarding this condition with value 400Mhz at frequency 1GHz.On this paper, the low pass filter also gives the pass band filter on frequency 3.2GHz which is constructed by the artificial ground structure. The simulation results with this design are simulated by computer based on finite integration method and show a good agreement and can be performed for a low pass band filter applications in the future. Keywords: low pass filter, less via, artificial ground structure

Reconfigurable Device

ABSTRACTStacked layered pin a-SiC/a-Si devices based on a filter design are approached from a reconfigurable point of view. This paper shows that a double SiC/Si pin photodiode can be de-composed into two photonic active filters changeable in function. Reconfiguration is provided by optical control signals to the optoelectronic front and back pin building blocks. Depending on the wavelength and irradiation side of the external optical bias the device acts either as a short- and a long- pass band filter or as a band-stop filter, amplifying or rejecting a specific wavelength range. Particular attention is given to the amplification coefficient weights, which allow taking into account the wavelength background effects. We illustrate these effects in detail and discuss the filters transfer function characteristics. We present examples of filters and we propose a reconfigurable device for directed optical logic. An algorithm to decode the information is presented. An optoelectronic model supports the optoelectronic logic architecture.
