Abstract. A new sensor for measuring low-amplitude magnetic fields that is ideal for small spacecraft is presented. The novel measurement principle enables the fabrication of a low-cost sensor with low power consumption and with measuring capabilities that are comparable to recent developments for CubeSat applications. The current magnetometer, a software-modified version of a commercial sensor, is capable of detecting fields with amplitudes as low as 8.7 nT at 40 Hz and 2.7 nT at 1 Hz, with a noise floor of 500 pT/√(Hz) @ 1 Hz. The sensor has a linear response to less than 3 % over a range of ±100 000 nT. All of these features make the magneto-inductive principle a promising technology for the development of magnetic sensors for both space-borne and ground-based applications to study geomagnetic activity.

Abstract. A new sensor for measuring low-amplitude magnetic fields that is ideal for small spacecraft is presented. The novel measurement principle enables the fabrication of a low-cost sensor with low power consumption and with measuring capabilities that are comparable to recent developments for CubeSat applications. The current magnetometer, a software-modified version of a commercial sensor, is capable of detecting fields with amplitudes as low as 8.7 nT at 40 Hz and 2.7 nT at 1 Hz, with a noise floor of 4 pT∕Hz at 1 Hz. The sensor has a linear response to less than 3 % over a range of ±100 000 nT. All of these features make the magneto-inductive principle a promising technology for the development of magnetic sensors for both space-borne and ground-based applications to study geomagnetic activity.

Aimed at the problem of the embedded multi-channel video acquisition and display system, a new one based on FPGA is put forward. The configuration of the system is given. The principle and key issue is analyzed. Using of the state shift mechanism, t the controlling time sequence signals of TFT-LCD are produced; The synchronization among multi-channel video acquisition is realized by using time-division multiplexing technology; The problem of conflict between reading and writing frame cache is solved through the two SRAM switch; The frames composition technology is applied to accomplish the change from interlaced scanning to progressive scanning. The result of project application shows the virtues of system, such as good effect of acquisition and display, low cost and low power consumption.

This article studies the embedded SPC and its application in roundness measuring system by analyzing the current roundness measurement principle and technology. With analyzing the process of data collection, date treatment and various kinds of tool graphic construction, we study the feasibility of integrating SPC into roundness measurement and finally apply the embedded SPC as pure software into roundness measuring system. We design the roundness measuring system based on embedded SPC and develop the roundness measuring system of low power consumption, high accuracy and easy application, which is suitable for industry field usage.

In order to process and analyze the signal of frequency modulated continuous wave (FMCW) radar, a radar semi-physical simulation(RSPS) system based on STM32F103VE6 chip is designed in this paper. By designing the hardware and software of system, the RSPS system can process the radar signal, detect the target, verify the data process algorithm and display the result on TFT-LCD screen. In addition, the collected data can be uploaded to PC by RS-232 interfaces which improves the reliability, stability and practicability of system. The waveform and spectrum maps are utilized to show the feasibility of RSPS system in analysing FMCW radar signal. Experimental results show that this system has many advantages, such as multifunction, low power consumption and low cost.

Wireless technology has walked into the People's Daily life, Bluetooth technology comes to the fore in so many wireless technologies with its low power consumption, low cost and other characteristics. Bluetooth technology is used widely, we can see it in mobile phones or in our cars, it seems that Bluetooth technology has penetrated into every aspect of our lives. Even so, the combination of Bluetooth technology and fixed telephone still has a very big development space. If the stability of the fixed telephone combined with the flexible of Bluetooth technology, it will give the life of people a lot of convenience. This paper will introduces the Bluetooth hands free system for fixed telephone, it is such a product that it will make Bluetooth technology and common fixed phone combined, and make it a reality that people can use common Bluetooth headset to answer or call a fixed telephone.

A high-performance and low power consumption triple-node upset self-recoverable latch (HTNURL) is proposed. It can effectively tolerate single-node upset (SNU), double-node upset (DNU), and triple-node upset (TNU). This latch uses the C-element to construct a feedback loop, which reduces the delay and power consumption by fast path and clock gating techniques. Compared with the TNU-recoverable latches, HTNURL has a lower delay, reduced power consumption, and full self-recoverability. The delay, power consumption, area overhead, and area-power-delay product (APDP) of the HTNURL is reduced by 33.87%, 63.34%, 21.13%, and 81.71% on average.
