The knee joint functions as a stabilizer for the lower extremity during weight bearing and allows large range of motion for various functional activities. The two primary articulations of the knee joint are the tibiofemoral joint and the patellofemoral joint.
1. electrocardiogram recorded between one limb and two other limbs. The augmented leads are designated aVF, aVL, and aVR for recordings made between the foot (left), left arm, and right arm, respectively, and the other two limbs. The definition information for augmented lead is provided by Stedman's.
with a single-cell Li-Ion source, the sum of the voltage drop across the white LED and the current source can be lower or higher than the battery voltage. This means that a white LED requires the battery voltage to be occa-sionally boosted. The best way to accomplish this is to use a step-up DC-DC converter. This method significantly optimizes efficiency at the expense of cost and PCB area. An alternative method of boosting the battery voltage is to use
