Signal and information management of neural recordings for complex neural interface system become a very difficult task. Recently we develop a framework for complex neural interface system aimed at processing neural signals with multisensor fusion approaches. The relationship of the data fusion with the whole system is detailed discussed. A general fusion and control architecture for complex neural interface system is proposed. In this work, using the proposed approach we make an illustrative experiment by exploiting the Sleep Heart Health Study Polysomnography (SHHS) Database to seek to integrate with the ECG, EEG, EOG and other neural signals, and propose a good solution to the investigation of clinical neural medicine.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121743838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first device developed uses standard CMOS IC, and it can provide bipolar interval pulse sequence as electrical stimulation in order to avoid the effect of direct current The function of the second device is specified by software rather than by silicon hardware, allowing a single device to be programmed for different functions.

It's desirable to create intelligent computer systems that understand users' emotional states. In this paper we report on our efforts in developing multimodal affective user interface system used in emotion assessment. First, we discuss the importance of emotion research. Secondly, we introduce the prototype MAUI system built in BABYLAB. There are different modalities of synchronous inputs from the user using wireless sensors and multimedia computer sensing, including physiological signals, facial expressions, speech signals, and behavioral data. The physiological signals are collected using wireless remote sensors in real time. The images of facial expression and the ongoing videos of behavior and gesture are recorded by several cameras connected to different controlling computers. Signals captured simultaneously during experiments are saved in order to discern emotional state from processing sensory modalities over time. All these signals and experiments are collected synchronously in real time to make multimodal signal analysis convenient. Then, using this system, we present preliminary results from an exploratory study that aims to estimate emotion state with non-invasive technologies, which are mapped to their corresponding emotions. Finally, we discuss usages of this system in educational area, and people may benefit from improved satisfaction in learning and training.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133563933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then with the Adaboost classifier, the satisfactory classification results on test data can be obtained. The maximum classification accuracy reaches to 89.29% and the maximum mutual information is 0.59bit.

In previous many works, researchers have dealt with steady EMG and have proposed analyzing methods being suitable for the EMG, for example FFT and STFT. Therefore, it is difficult for the previous approaches to discriminate motions from the EMG in the different phases of muscle activity, i.e., pre-activity, in activity, post-activity phases, as well as the period of motion transition from one to another. In this paper, we introduce the wavelet transform using the Coiflet mother wavelet into our real-time EMG prosthetic hand controller for discriminating motions from steady and unsteady EMG. A preliminary experiment to discriminate three hand motions from four channels EMG in the initial pre-activity and in activity phase is carried out to show the effectiveness of the approach. However, future research effort is necessary to discriminate more motions much precisely.","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115723716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The action potential can be simulated by the general-purpose circuit simulation program, such as HSPICE. The responses of the microelectrodes act as a function of several parameters, such as the sealing resistance and input resistance of the preamplifier. The responses are not sensitive to the changes of the microelectrode parameters. However, appreciable influence of the parasitic capacitance was obtained when the sealing resistance was large (e.g. 100M/spl Omega/).","PeriodicalId":169717,"journal":{"name":"Proceedings. 2005 First International Conference on Neural Interface and Control, 2005.","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125390992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to various sources of noise, such as, seal leakage, electronic noise in the equipment, and shot noise in the channel. Firstly wavelet packet (WP) analysis is applied denoise, the error analysis shown that max error is 10.658fA, the result shown patch-clamp signals exist partially noise eliminated.
