RESUMO
OBJECTIVE: Assessing automatic feedback technologies to promote safe travel and speech loudness control in two men with multiple disabilities, respectively. METHOD: The men were involved in two single-case studies. In Study I, the technology involved a microprocessor, two photocells, and a verbal feedback device. The man received verbal alerting/feedback when the photocells spotted an obstacle in front of him. In Study II, the technology involved a sound-detecting unit connected to a throat and an airborne microphone, and to a vibration device. Vibration occurred when the man's speech loudness exceeded a preset level. RESULTS: The man included in Study I succeeded in using the automatic feedback in substitution of caregivers' alerting/feedback for safe travel. The man of Study II used the automatic feedback to successfully reduce his speech loudness. CONCLUSION: Automatic feedback can be highly effective in helping persons with multiple disabilities improve their travel and speech performance.

Objective To design and develop a cardiovascular automatic feedback control instrument for rescuing the critical patients.Methods Ten dogs used this kind instrument and the effects were obserred.Resuts The experiment of the dogs showed:the computer collected samples promptly,accurately and rapidly,and the instrument could help us to reach the expected goal.Conclusion In animal experiments,it showed that the whole cycle,from obtaining blood pressure to adjusting the amounts of medicine through feedback,was shortened.The calculating was accuratel and curative effect was reliable.This instrument is wait to be apprnsed by clinic.
