Wearable Healthcare monitoring system is very important and necessary especially in remote areas. The problem under study is to improve healthcare systems. In existing systems, the power consumption, cost is too high. Also there is no privacy in the system for the database protection which is prone to security attacks. The proposed system will implement a sensor interface with ultra low power msp430 microcontroller, physiological sensors such as Heart rate sensor, Temperature sensor, Humidity sensor, Acceleration sensor, Zigbee transceiver for wireless transmission integrated in jacket. The proposed system designs a healthcare monitoring system which is connected to physician server or medical server through the internet.

To realize the efficient and stable real-time monitoring and intelligent management of the urban public lighting, the remote monitoring system is developed. The system is composed of monitoring center and monitoring terminals, and realizes network connection via the advanced remote wireless communication technology GPRS. It uses TI Company's msp430 processor chip as the monitoring terminal controller, which integrates automatic control, data acquisition, communication and other technologies and has such functions as monitoring, remote control, anti-electricity theft, remote meter reading and communication. It's proved by practice that the designed controller features reliable running, sound real-time performance and low cost, and has a broad and bright application prospect. The monitoring and management of public lighting is a typical sector and important part of the civil work. Due to the continuous development of urban construction and ever-enlarging lighting coverage, the traditional lighting management methods can not realize centralized monitoring, have poor real-time performance and cost lots of human and material resources;thus, can not satisfy the requirements of energy saving and efficiency improvement[1]. GPRS (General Packet Radio Service), the wireless packet exchange technology based on the second generation mobile communication system GSM, is very suitable for transmitting non-continuous, unexpected and small sets of street lamp monitoring data. Also, quick & easy log-on, real-time online, high-speed transmission, sound economical efficiency and many other advantages make GPRS become the first choice for remote measurement and control system[2]. Therefore, the development of GPRS-based public lighting remote monitoring system becomes a necessity. The designed monitoring system in this article is a typical distributed monitoring and data acquisition system integrating computer technologies, modern communication technologies and automatic control technol

In view of the problem that the large room switches and other network equipment were damaged by lightning and other disasters for lack of timely protection, so the remote control system based on Embedded Web server has been put forward. The system connects the ultra low power consumption microprocessor msp430 SCM with CS8900A Ethernet network control chip, based on C programming language by transplanting the open-source uIP embedded TCP/IP protocol stack, so that the users can use the browser to login webpage embedded Web remote control system, and realize the remote control of network equipment room. What's more, the system has been put into use in Nantong University network and server computer room, and its practical application has shown that the system is stable and reliable. Thus, it has good application value.

This paper describes our custom-designed wireless gait analysis sensor (WGAS) system developed and tested for real-time fall detection. The WGAS is capable of differentiating falls vs. Activities of Daily Living (ADL) and the Dynamic Gait Index (DGI) performed by young volunteers using a Back Propagation Artificial Neural Network (BP ANN) algorithm. The WGAS, which includes a tri-axial accelerometer, 2 gyroscopes, and a msp430 microcontroller is worn by the subjects at either T4 (at back) or the belt-clip positions (in front of the waist) for the various falls, ADL, and Dynamic Gait Index (DGI) tests. The raw data is wirelessly transmitted from the WGAS to a nearby PC for real-time fall classification, where six features were extracted for the BP ANN. Overall fall classification accuracies of 97.0% and 97.4% have been achieved for the data taken at the T4 and at the belt position, respectively. The preliminary data demonstrates an overall sensitivity of 97.0% and overall specificity of 97.2% for this WGAS fall detection system, showing good promise as a real-time low-cost and effective fall detection device for wireless acute care and wireless assisted living.

In this paper, a wireless electroencephalography (EEG) acquisition analog front-end (AFE) circuit design is presented. The wireless EEG acquisition system includes an analog front-end readout chipset (AFERC) with extendable channel, a low-power msp430 microcontroller from Texas Instruments and a commercial Bluetooth 2.0 module (BTM). The front-end readout chipset not only applies the ability of noise attenuation but also modulates the EEG signal into appropriate amplitude. It has individual 10-bit successive approximation register analog-to-digital converter (SAR-ADC) for each EEG channel, and it transmits the EEG signals which have been serially converted to digital format to msp430. msp430 is responsible for rearranging the converted digital bits and controlling the BTM with built-in Universal Asynchronous Receiver/Transmitter (UART) interface. The AFERC maximumly reaches to 64 channels, and single channel consumes 80.268 uW. Total power consumption of AFERC is 2.6 mW at with 32 channels, and its Common-Mode-Reject-Ratio (CMRR) is 75 dB.

Optimal power and performance trade-offs for dynamic voltage scaling in power management based wireless sensor node

Perspectives in Science 2016年 8卷 536-539页

Dynamic voltage scaling contributes to a significant amount of power saving, especially in the energy constrained wireless sensor networks (WSNs). Existing dynamic voltage scaling techniques make the system slower and ignore the event miss rate. This results in degradation of the system performance when there is non-stationary workload at input. The overhead due to transition between voltage level and discrete voltage levels are also the limitations of available dynamic voltage scaling (DVS) techniques at sensor node (SN). This paper proposes a workload dependent DVS based msp430 controller model used for SN. An online gradient estimation technique has been used to optimize power and performance trade-offs. The analytical results are validated with the simulation results obtained using simulation tool “SimEvents” and compared with the available AT9OS8535 controller. Based on the stochastic workload, the controller's input voltage, operational frequency, utilization, and average wait time of events are obtained.
