Distress caused by a verbal barrier which hinders the subjects from being able to communicate freely and easily to sign language incapable individuals and vice-versa is the focal point of concern this project aims to resolve. This communication device consists of two major parts: (1) a surface consists of two Bare Conductive Touch Boards preloaded with the twelve phrases and words with its corresponding display of hand sign images converted to its English translation and (2) two TFT Touch Shields mounted in Arduino Mega 2560 Rev3 respectively, preloaded with the standard English alphabet and American Sign Language symbols. The impaired subjects have two options either to tap the desired electrode pads on the Touch Board or to communicate using the TFT Touch Shield like a multi-touch texting option. On the other hand, the normal user communicates only via TFT Touch Shield. Chat Box is a communication device that bridges the language gap of a deaf, mute and deaf-mute, sign language capable individuals to those of normal, non-sign language people. The Chat Box indeed is an innovative piece of technology that has a potential of altering the inconvenient manner of conversing with the speech and hearing impaired community. The third-party programs and software proved the authenticity of the device by verifying its accuracy, consistency, speed (timing and delay) and responsiveness in terms of transmitting data from one LCD shield to the other, as well as the rate of the instantaneous audio produced once the electrode pads were tapped.
由于语言障碍而造成的痛苦，阻碍了受试者能够自由和轻松地与不具备手语能力的人交流，反之亦然，这是该项目旨在解决的关注焦点。该通信设备由两大部分组成:(1)表面由两块Bare Conductive Touch board组成，预加载12个短语和单词，并显示相应的翻译成英文的手势图像;(2)两块TFT Touch shield分别安装在Arduino Mega 2560 Rev3上，预加载标准英语字母和美国手语符号。受损受试者有两种选择，要么点击触摸板上所需的电极垫，要么使用TFT触屏进行交流，就像多点触控短信选项一样。另一方面，普通用户只能通过TFT触屏进行通信。Chat Box是一种沟通工具，它可以弥合聋哑人、聋哑人、手语使用者与正常人、非手语使用者之间的语言差距。聊天盒确实是一项创新的技术，它有可能改变与语言和听力受损人士交谈的不方便方式。第三方程序和软件通过验证其从一个LCD屏蔽到另一个LCD屏蔽传输数据的准确性，一致性，速度(定时和延迟)和响应性，以及触点电极垫后产生的瞬时音频速率来证明设备的真实性。

NFC chip can capture power from antenna when it is in magnetic field. At the same time, NFC chip may also be powered by battery at IoT application, and it needs to shutdown battery supply to save battery energy, which makes it complex for power switch architecture. This paper presents an architecture and circuit design for NFC chip to switch power between battery and magnetic field inducing energy. An offchip 1 uF capacitor is used to filter the magnetic field power swing in wireless communication time. This circuit also collects the magnetic field inducing energy and output a current as large as 5mA (3.3V) for other IoT chip or charging battery.

In this paper, we reported a supercritical treatment technology to suppress the positive shift in threshold voltage. After treatment, threshold voltage shift ($triangle$ Vth) under forward gate bias stress decreased from 4.05V to 0.15V, gate leakage current was reduced from 10-9mA/mm to 10-11mA/mm. It was suggested that nitrogen ions could modify interface state traps with a broad distribution of trapping, leading to suppressed gate leakage current and threshold voltage drifts.

Microfluidic devices and electrical techniques based on electrical impedance and viscoelastic changes can be used in the measurement of cancer cells in the epithelial-mesenchymal transition (EMT) process. Electrical impedance and transmission time were investigated when a single CRC cell passed the measurable tiny channel which was designed with width smaller than the average diameter of a single cell. The experimental data showed that the electrical impedance characteristics and viscoelasticity of the cells were changed after PMA induction. This property is expected to become a new biomarker for studying EMT.

A modified lateral DMOS-SCR with high holding voltage for electrostatic discharge (ESD) protection applications has been proposed in this paper. The proposed MLDMOS-SCR possesses a lower trigger voltage as well as a higher holding voltage, which is very suitable for 18V/20V ESD applications. The operation mechanism of MLDMOS-SCR device is discussed in detail, and the effect of floating P+ region on the MLDMOS-SCR’s I-V characteristics is analyzed by TCAD simulation as well.

The electronic and optical properties of Zn-doped sphalerite BN crystals were investigated by first-principles calculations based on density functional theory. The results show that the intrinsic c-BN is an indirect bandgap semiconductor and exhibits a certain degree of P-type traits. The incorporation of Zn reduces the band gap of BN, but introduces more carrier density near the Fermi level of the valence band. Compared with pure BN, the real spectrum of the dielectric function of Zn-doped BN is less stable in the low-energy region, but there is still a range of available light transmission, while the imaginary part has less variation and has a similar absorption range. It is shown that Zn-doped BN can be used for light-emitting elements in a certain spectral range.

In order to overcome the shortcomings of existing location algorithms, which can’t make full use of the location information of multi-hop anchor nodes, and obtain the ideal result of node localization, a new range-free location algorithm for wireless sensor networks is proposed in this paper—n-hop anchors’ connection relationship-based localization (NHCRL) algorithms. The key point of this algorithm is that to use anchor nodes with different hop values as geometric constraints of unknown node positions, and then to reduce their location areas continuously to achieve the purpose of accurate positioning. The simulation results show that under the same conditions, compared with the traditional location algorithm, NHCRL has higher location accuracy.

A novel dual-mode ridge waveguide structure is proposed to design dual-band bandpass filter in this paper. This new configuration achieves to realize two orthogonal resonant modes which allows for independent control of the two resonant frequencies. In addition, a transmission zero is introduced in the guard-bands improving the filter selectivity, while keeping a simple and compact inline topology.

Automated bioelectric signal analysis has an important application in the wisdom medical care. In this work, we focus on ECG-signal and address a novel approach for cardiac arrhythmia diseases classification. We designed a novel analysis framework which extract different feature transformations from ECG signals. And we trained the SVM model for multi-feature to obtain the prediction. Finally, we tested our approach on the public database of MIT-BIH arrhythmia. And the results of experiments on the database demonstrate our model has better classification performance than other approaches.

This paper introduces a design scheme of a software defined radio (SDR) processing platform based on ZYNQ7000 and AD9371. Supports signal acquisition and processing in the 300MHz-6000MHz tunable range with up to 100 MHz bandwidths. The system was implemented on a 160mm*100mm board, greatly reducing the number of chips and PCB layout space. The transceiver performance of the system was tested and verified, especially spurious suppression and IQ balance.
