Downward migration of knee exoskeletons under external forces is one major concern against their normal operations. It may be reduced by increasing the friction between and human thigh. However, effectiveness control remains questionable, as natural inverted-cone shape thigh will aggravate downward migration, overwhelming strapping intensity degrade activation level muscles. In this paper, we p...

Contemporary land-survey micro-satellites have general mass up to 100 kg and are placed on the orbit altitudes from 600 up to 800 km. For such spacecraft some principle problems on attitude determination, in-flight calibration and alignment are considered and elaborated methods are presented for their solving. We present discrete algorithms for calibration and alignment of the low cost strap-do...

We report the imaging and pathologic findings of fishbone-associated actinomycosis of the anterior cervical space in a 57-year-old man, misdiagnosed preoperatively as a malignancy originating from thyroglossal duct cyst. CT revealed an enhancing mass containing a small abscess pocket and two sharp linear calcifications within it, which infiltrated into the strap muscle. Pathologic examination d...

Background and purpose The direct forces exerted by the brace pad were analysed, on 44 idiopathic scoliotic patients (38 girls, 6 boys) treated with a DDB [1]. Twenty seven patients had a single right thoracic curve and 17 had a single left or right thoracolumbar curve. The aim was the analysis of the corrective forces, exerted at the skin-brace interface, by altering the posture, activity and ...
