In the rehabilitation field, there is a need for quantitative evaluation independent of the therapist’s subjective evaluation. In our previous work, we developed a binary-valued quantitative evaluation algorithm for the motor function of the shoulder joint based on sensor data from a test performed by therapists. In this paper, we developed a quantitative evaluation support system by implementing the binary-valued quantitative evaluation algorithm of the motor function and verified the effectiveness of the proposed system. The quantitative evaluation support system uses a three-dimensional force display robot that can imitate the test motion and the evaluation by the therapist. For this purpose, we analyzed the test motion and the evaluation by the therapist for ten subjects to determine two threshold parameters used in the binary-valued quantitative evaluation algorithm. In order to verify the evaluation accuracy in the test using the developed quantitative evaluation support system, we conducted the test using the developed system for three subjects. The sensitivity was 75% and the specificity was 75% in the test using the developed system. We plan to improve on the evaluation accuracy in our future work.

We have developed a new rehabilitation support system, UR-System 2, for restoring the motor function of a plegic upper limb after a stroke. Its design is based on knowledge gained during clinical testing of the UR-System. The UR-System 2 was equipped with the facilitating function of elbow extension based on the proprioceptive neuromuscular facilitation technique and the measurement function for evaluating isolated movements. In this study, we verified the effectiveness of the facilitating function on a patient. In addition, we verified the immediate recovery effect of training with the UR-System 2 on a patient. In this training, elbow flexion and extension of the paralyzed forearm were repeated 150 times. As a result, we confirmed the improvement of isolated movements, namely the decrease in pronation torque of the paralyzed forearm during training and the suppression of the pronation angle before and after training. Moreover, the active ranges of motion and the modified Ashworth scale score improved after training, which indicated a reduction in spastic paralysis. These results show the immediate recovery effect of training with the UR-System 2 for restoring the motor function of the upper limb.
EMBROIDERY PATTERN GENERATION BY SEWING MACHINE
Yasumichi Hasegawa,Kihachi Takeichi,Tsuyoshi Matsuo 전력전자학회 1995 ICPE(ISPE)논문집 Vol.1995 No.10
It is proposed that embroidery patterns are generated by using sewing machine. The equipment with sewing machine are mainly composed of a mathematical model which may be constructed by switching and other circuits. The model is called the commutative linear representation systems. Many methods of image generation being mainly intended for the realism of images, this method is a very different graphic generation from them. Embroidery pattern generation is a trial for a sort of graphic art by using sewing machine with computer, Being executed in linear operations, this generation method may be very suitable for computer algorithm or electric circuits. The effectiveness of this method is illustrated with several examples.

This paper is suggesting a new technology for refrigerant amount detection of a system air-conditioner installed under various installation conditions. System air-conditioner was introduced to domestic market first in 2000. It consists of one or a series of outdoor units and a number of indoor units connected with single pipe line to the outdoor unit. The system can vary the capacity from 2.0 kW to 186 kW. For the system Installed under long and high-elevated condition, about 100 kg of refrigerant is charged in the whole system. In this paper, the new technology RAD (Refrigerant Amount Detection) with edge technology of refrigerant cycle control and measurement of a system air conditioner was developed and investigated for its application for the various installation conditions.
