The channel characteristics of the body area network are important to transmission rate and transmission robustness. Current explorations mainly concern the channel characteristics in static state of the human body. In this paper, we establish human motion models of sitting to standing, walking and running postures, and calculate the path loss values in 2.4GHz for the models. The experimental results show that the path loss values vary sharply in the process of human movement, which is very helpful to determine the transmission power and design BAN sensor nodes.

Peak Delay (PD) of two different blood pulse waves measured at the same site is intensively studied in this paper. The derived expression, based on Womersley theory and simplified Navier-Stokes equations, implies that PD is closely related to the change of the Young's modulus of the blood vessel, which is promising in noninvasively BP monitoring. Traditionally, BP is estimated with Pulse Transit Time (PTT) or Pulse Arrival Time (PAT). Experiment results show that PAT and PD are inversely related with correlation coefficient from 0.78 to 0.95 when BP is relatively stable. If BP changes remarkably, calibration should be conducted to better trace PAT with PD. Therefore PTT or PAT can be replaced by PD for continuous and noninvasive BP monitoring, with the convenience that the measuring site is concentrated on fingertip.

Ultrasound thyroid nodules segmentation is a much tough task due to the speckle noise, intensity heterogeneity, and low contrast. In this paper, we introduce an effective segmentation method to make the problem better. Our works are composed of pre-processing, extracting boundaries, postprocessing. First, we suppress the speckle noise by speckle reducing anisotropic diffusion method. Second, we introduce a reasonable and effective speed stopping term based local phase symmetry feature which is theoretically intensity invariant, and the new speed stop term is incorporated into distance regularized level set evolution. Then, to remedy the emerging problems, we do some effective post-processing. Qualitative and quantitative comparative results demonstrate the superiority of our proposed method.

The Circle of Willis (CoW) is a circulatory anastomosis that supplies blood to the brain and surrounding structure. Detecting and quantifying the CoW is essential for the prevention and treatment of aneurysm rupture and cerebral Infarction. In this paper, we present a robust interactive method to segment CoW mesh model from the whole cerebrovascular mesh base on graph-cut. First we construct the weighted graph G based on the input sketch. Then we find the minimum cost along the partitioned edges with Min-Cut/Max-Flow method. Moreover, we combine the shape-diameter function (SDF) and the angles between the normal vector of the neighbor face to construct the penalty energy which makes the method stable. Computational results show that the proposed interactive algorithm is robust, real time performance and friendly to user.

In this paper, a wideband Current Source (CS) for System on Chip (SoC) Bio-Impedance Spectroscopy (BIS) application is presented. The circuit consists of a load-in loop inverting amplifier current source back-end with a PMOS Pseudo-Resistor (PR) feedback, and a Norton current source front-end drive in the form of a Second Generation Current Conveyor (CCII). The load-in-loop structure allows a differential interface to the Sample Under Study (SUT) permitting the four-point probe interface. The use of a PR array results in the creation of a high impedance feedback while consuming small chip area. The CCII drive increases the output impedance of the CS towards the MHz range. Comparison of 6 load-in-loop CS (LL-CS) structures confirm the performance of our design in terms of output impedance, and excitation current precision over a wide frequency range covering the beta-dispersion range of BIS (~10MHz). The LL-CS structures are realized using TSMC 0.35um CMOS 2P4M Mixed Mode Technology.

This paper was proposed for the feature extraction problem in Brain Computer Interface (BCI) which was based on the motor imagery. Common Spatial Pattern (CSP) was used to extract useful features from the Electroencephalograph (EEG) signals. Firstly, a preprocessing step was applied to remove noises. Secondly, CSP was used to analyze with EEG signals. Support Vector Machine (SVM) was investigated to classify motor imagery state. The EEG signals of motor imagery provided by dataset I of 2004 BCI Competition III were used for the validation. The results showed that the algorithm can extract the obvious characteristics efficiently. Finally, the proposed method was used in a wheelchair application. Experimental results showed that the proposed approach was promising for implementing human-computer interaction, especially for EEG-based brain controlled wheelchair.

In this paper, we used an experimental platform based on cellular impedance sensors to study cellular changes after hyperthermia treatments. Impedance profiling showed high correlation with traditional MTT results, thus the impedance data represent cell viabilities very well. Then, status of cells under six typical hyperthermia treatments with different temperatures between 41-46 °C and different treating durations (0-30 min, 45 °C) were examined by the platform separately. The results showed increasing cell damage occurred when temperature or duration increased, and indicated the thresholds of temperature (~43 °C). Moreover, it is possible that a thermal isoeffect dose (TID) threshold exists in the two cell lines (equivalent time at 43 °C EM43=30~40 min). These results fit previous theories of hyperthermia, demonstrating that the cellular impedance sensor is a useful analytical tool for the in vitro research of thermal therapy.

Below-knee amputation is one of the most critical types of amputations related to gait disability. A very effective therapy is to replace the amputated part by a robotic prosthetic lower limb. This limb consists of different design parameters with most important and crucial being its actuator. Since the power transmission to the foot and movement control is directed through the actuator, it is very important to use an actuator which fulfills all the vital parameters required for the prosthesis to work effectively i.e. weight, torque and speed. Conventional actuators available on the market do not control all these parameters. The purpose of this paper is the development of an effective actuator design, for assisting robotic prostheses that can be used by amputated people in the everyday environment to obtain natural gait. The presented design has been validated using finite element analysis (FEA).
