In this work, we approach this detection problem based on the use of a small magnet marker attached to a finger and a miniature magnetometer installed within the eButton. Our experimental results indicate that our magnetic approach is effective when the distance between the marker and the wearable computer is within 12cm, and the range of detection is approximately 15cm. We also found that the proximity signal patterns corresponding to eating and other daily activities are different, which can be used to reduce the false detection rate. In addition, our approach is convenient, low-cost and energy efficient, suitable for practical applications.</p>","PeriodicalId":74545,"journal":{"name":"Proceedings of the IEEE ... annual Northeast Bioengineering Conference.

In this paper, a new framework, 3D/2D model-to-image registration, is presented for estimating food volume from a single-view 2D image containing a reference object (i.e., a circular dining plate). First, the food is segmented from the background image based on Otsu's thresholding and morphological operations. Next, the food volume is obtained from a user-selected, 3D shape model. The position, orientation and scale of the model are optimized by a model-to-image registration process. Then, the circular plate in the image is fitted and its spatial information is used as constraints for solving the registration problem. Our method takes the global contour information of the shape model into account to obtain a reliable food volume estimate. Experimental results using regularly shaped test objects and realistically shaped food models with known volumes both demonstrate the effectiveness of our method.</p>","PeriodicalId":74545,"journal":{"name":"Proceedings of the IEEE ... annual Northeast Bioengineering Conference.

However, the current EEG technology cannot be utilized quickly and conveniently at the point of care due to the complex skin preparation procedures required and the inconvenient EEG data acquisition systems. This work presents a portable amplifier design that integrates a set of skin screw electrodes and a wireless data link. The battery-operated amplifier contains an instrumentation amplifier, two noninverting amplifiers, two high-pass filters, and a low-pass filter. It is able to magnify the EEG signals over 10,000 times and has a high impedance, low noise, small size and low weight. Our electrode and amplifier are ideal for point-of-care applications, especially during transportation of patients suffering from traumatic brain injury or stroke.</p>","PeriodicalId":74545,"journal":{"name":"Proceedings of the IEEE ... annual Northeast Bioengineering Conference.

Effects of lipids on dissolution of poorly water-soluble drugs 脂类对难水溶性药物溶解的影响

In order to determine the impact of lipid and lipid digestion on drug dissolution and absorption, an updated in vitro lipid digestion model has been designed based on knowledge of gastrointestinal contents. The digestion kinetics sensitivity to key parameters, including pH, calcium concentration, and lipid substrate, has been studied. In vitro lipolysis experiments have been coupled with several techniques, such as dynamic light scattering (DLS), and electron paramagnetic resonance (EPR), to characterize respectively: size and morphology of colloidal particles, and dynamic drug partitioning between phases.","PeriodicalId":74545,"journal":{"name":"Proceedings of the IEEE ... annual Northeast Bioengineering Conference.
