RESUMO
Objective To improve the DXC series of psychology test instrument and its supporting software.Methods The nRF905 chip and STC89LE516AD chip were used to design the question system.Results Such shortcomings in the DXC-5 system were improved as overweight,too many link-wires,too much time in the initial deployment,etc.Conclusion The system can be used to select not only flight personnel and cosmonauts,but also personnel in other special professions.
RESUMO
For the purpose of monitoring real-time information of infant bed-wetting,this paper presents a medical digital wireless monitoring system with low-cost and high-performance. Its hardware is based on micro-controller,MSP430 ultra low-power and RF IC,nRF905 single wireless chip. With this wireless system,real-time information of infant bed-wetting can be monitored,and thus the nurses' work load can be reduced.
RESUMO
Objective To design pedometer shoes through wireless transmission step calculation.Methods The transmitting terminals in the soles acquired the pressure signals,and then the signals were transmitted to the SCM after conversion,amplification and comparison.AT89S52 SCM was used for step calculation and then the results were sent to the receiver through nRF905.Results The receiver had three modes,such as the step-calculation mode with the time and step calculation result displayed,the running mode with the distance displayed and the function of stopwatch,and the prompt mode with the distance and consumed power displayed.Conclusion The wireless embedded pedometer shoes are multifunctional,easy to operate and reliable.
RESUMO
A system adapted for depot management in hospital based on RFID technology is introduced. With resolution of RFID from PHILIPS and RF transmission from Nordic VLSI Norway, the storage of medical materials and medical equipments can be identified, labeled and statistically controlled accurately and expediently. The system can not only save a mass of work force, but also improve work efficiency.
