TL;DR: This methodology, based on a balancing between processing and transmission tasks, can be applied in all those situations where subjective image based measurements are required and tries to find the best compression ratio able to give a significant reduction of transmission time.
Abstract: The paper presents a methodology to reduce the energy consumption of visual sensor node in wireless sensor networks. This methodology, based on a balancing between processing and transmission tasks, can be applied in all those situations where subjective image based measurements are required. Considering that in a sensor node, the communication task is the most energy consumption, the proposed method tries to find the best compression ratio able to give a significant reduction of transmission time, returning adequate and objective image quality and compression time. Some results are presented applying the proposed methodology to the particular case study: the use of wireless visual sensors to the remote metering of water counters.

TL;DR: SSVEP based BCI through Emotiv EPOC is implemented and the online experiments have the accuracy of 95.83±3.59 % and the information transfer rate (ITR) with 22.85±1.85 bits/min.
Abstract: In recent years, steady-state visual evoked potential (SSVEP) based brain-computer interface (BCI) has received much attentions. However, most SSVEP based BCI devices are not portable and have high price, which are not suitable to be used for clinical and commercial purpose. Thanks to the low cost and portable Emotiv EPOC, it brings BCI into daily life. In this paper, SSVEP based BCI through Emotiv EPOC is implemented. BCI 2000 is employed to connect Emotiv EPOC and Matlab to implement the online system. The online experiments have the accuracy of 95.83±3.59 %, information transfer rate (ITR) with 22.85±1.85 bits/min and detection duration of 5.25±2.14 sec.

TL;DR: This paper presents a robust and intelligent scheme for driver drowsiness detection employing the fusion of eye closure and yawning detection methods, and proves the high efficiency of the proposed idea.
Abstract: Driver drowsiness is a major factor in most driving accidents In this paper we present a robust and intelligent scheme for driver drowsiness detection employing the fusion of eye closure and yawning detection methods In this approach, the driver's facial appearance is captured via a camera installed in the car In the first step, the face region is detected and tracked in the captured video sequence utilizing computer vision techniques Next, the eye and mouth areas are extracted from the face; and they are studied to find signs of driver fatigue Finally, in a fusion phase the driver state is determined and a warning message is sent to the driver if the drowsiness is detected Our experiments prove the high efficiency of the proposed idea

TL;DR: A new concept of low-cost, high-resolution, lightweight, compact and highly-portable tactile display based on shape memory alloy (SMA) technology that allows the development of 60 g weight tactile devices of compact dimensions easily carried in the user's hand.
Abstract: This paper presents a new concept of low-cost, high-resolution, lightweight, compact and highly-portable tactile display. The prototype consists of an array of 8 /spl times/ 8 upward/downward independent moveable pins based on shape memory alloy (SMA) technology. Each actuator is capable of developing a 320 mN pull force at 1.5 Hz bandwidth by using simple forced-air convection. The proposed concept allows the development of 60 g weight tactile devices of compact dimensions easily carried in the user's hand. SMA active element, tactile actuator and tactile display are presented and discussed.

TL;DR: To increase the computational efficiency of the proposed system, a virtual ambisonic approach is used, that result in a bank of time-invariant HRTF filter independent of the number of sources to encode.
Abstract: Convincing binaural sound reproduction via headphones requires filtering the virtual sound source signals with head related transfer functions (HRTFs). Furthermore, humans are able to improve their localization capabilities by small unconscious head movements. Therefore it is important to incorporate head-tracking. This yields the problem of high-quality, time-varying interpolation between different HRTFs. A further improvement of human localization accuracy can be done by considering room simulation yielding a huge amount of virtual sound sources. To increase the computational efficiency of the proposed system, a virtual ambisonic approach is used, that result in a bank of time-invariant HRTF filter independent of the number of sources to encode.
