We have developed a new portable surface plasmon resonance (SPR) sensor with multi detection points, which consists a single LED and a linear CCD. The size and weight of this sensor are 170 mm (W) x 110 mm (D) x 150 mm (H) and 1.5 kg, respectively. The sensitivity of the SPR sensor is comparable to that of a conventional SPR sensor. A novel strategy for patterning antibodies inside a microchannel of the SPR sensor chip has also been developed for multi immunoassays. © 2007 CBMS.

InAs layers were deposited on glass and plastic (polyimide) film substrates by molecular-beam deposition at substrate temperatures of 180-280degC. Atomic force microscopy revealed flat surfaces with RMS roughness of about 10 nm. X-ray diffraction patterns indicated that the InAs layers are poly crystalline textured in the (111) plane with crystallite sizes around 30 nm. Hall effect measurements showed that the films exhibit the n-type conduction with electron concentrations around 5 times 10 18 cm -3 . An InAs film deposited on polyimide showed electron mobility of 460 cm 2 /Vs at room temperature.

It has been found that some huge overshoot in the sense of sup-norm may be observed when typical iterative learning control (ILC) algorithms are applied to LTI systems, even though monotone convergence in the sense of λ-norm is guaranteed. In this paper, a new ILC algorithm with adjustment of learning interval is proposed to resolve such an undesirable phenomenon, and it is shown that the output error can be monotonically converged to zero in the sense of sup-norm when the proposed ILC algorithm is applied. A numerical example is given to show the effectiveness of the proposed algorithm.

IEEE International Conference on Robotics and Automation (ICRA)

作者： Thomas Delwiche Michel Kinnaert Faculty of Applied Science Department of Control Engineering and Systems Analysis Université Libre de Bruxelles Brussels Belgium

In this paper, an adaptive control structure based on the well-known four-channel (4C) control architecture is proposed to achieve transparency in non-ideal (high friction) teleoperation devices. The choice of the parameters to be adapted is motivated using a modified version of the 4C model. Next, two experiments are proposed to define the boundaries of the parameters values to be tuned during the adaptive process. Finally, the adaptive control scheme is successfully applied experimentally to a one degree of freedom (dof) teleoperation device.

An artificial realization of decision making for sleep stages of EEG (electroencephalograph) contaminated with artifacts was developed in order to construct a reliable sleep stage recognition system for clinics. The methodology was based on the conditional probability of knowledge-base of expert visual inspection. Expert visual inspection was the manual scoring result of sleep stages by a qualified EEGer (F.K.). Knowledge-base was constructed in terms of probability density functions of characteristic parameters with each sleep stage, according to the expert visual inspection. Artificial realization of decision making for sleep stage was based on the value of conditional probability. Totally, the overnight sleep EEG recordings of four subjects were analyzed. The results showed a close agreement with the expert visual inspection by EEGer. ©ISAROB 2007.

Active Eye-tracking System by Using Quad PTZ Cameras

Active Eye-tracking System by Using Quad PTZ Cameras

Annual Conference of Industrial Electronics Society

作者： Chao-Ning Chan Shunichiro Oe Chern-Sheng Lin Department of Intelligence Systems and Information Science Faculty of Engineering University of Tokushima Japan Department of Automatic Control Engineering Feng Chia University FCU Taichung Taiwan

There have been many researches on eye-tracking systems to estimate eye gaze and integrated with head movement tracking. In this paper, we describe an active eye- tracking system that can provide usability improvement of human-machine interface (HMI) with quad PTZ cameras. We propose an active tracking architecture for real-time eye- tracking in an open environment to get a wide-angle and long-distance available range. We implemented four following parts: face tracking module by Adaboost algorithm, eye detection module by Cognitive calibration algorithm, active control module by integration algorithm and input control module by diagonal-box checker search. We presented an active eye-tracking system that users can use it in unrestricted posture with different angles and distance to the pc. It can calculate the camera target position and then map the gazing point to screen coordinate. We can choice any user to track eye gazing when there are multi-users in front of the pc. The results provide a useful HMI for large head motion and long distance usages.

In this paper we describe an active gaze-tracking system that can provide an interactive interface with computer by using PTZ cameras. We propose an active tracking architecture for real-time gaze-tracking in an open environment and recorded the data into the database for diagnosis. When the cursor is out of control by gazing, a technical improvement theory is used to account for the reflective action of psychological natural reaction to correct the relevant process automatically. This architecture consists of four following parts: face tracking module, eye tracking module, active control module and input control module. We present a high accuracy gaze tracking system which can dynamically estimate the better target position of four PTZ and map the gazing point to screen coordinates. A user can use the active gaze-tracking system without difficult calibration and restricted posture.

The so called "super-exponential" methods (SEMs) are attractive methods for solving multichannel blind deconvolution problem. The conventional SEMs, however, have such a drawback that they are very sensitive to Gaussian noise. To overcome this drawback, the robust super-exponential methods (RSEMs) were proposed for single-input single-output infinite impulse response (SISO-IIR) channels and for multi-input multi-output (MIMO) static channels (instantaneous mixtures). While the conventional SEMs use the second-and higher-order cumulants of observations, the RSEMs use only the higher-order cumulants of observations. Since higher-order cumulants are insensitive to Gaussian noise, the RSEMs are robust to Gaussian noise. We proposed an RSEM extended to the case of MIMO-FIR channels (convolutive mixtures). To show the validity of the proposed RSEM, some simulation results are presented. © 2007 EURASIP.
