An apparatus for training the ocular muscles and measuring the angles of squint has two housings 7 and 8 pivotable about axes A-A by means of pivot pins 2 and 3 which are slidably adjustable to allow for different pupillary distances and carry mirrors 17, which are rotatable about axes A...
1 N·m of torque applied to a rigid body while it turns through a 1 radian angle around its axis will add 1 J to its kinetic energy. Some people call the unit of torque ‘Joules per radian’. As JC says, apply a factor of 2π if it makes a full turn, in some applications this...
They were children with convergent fixed squint (angle: from +4 degrees to +26 degrees) with convergent fixation. The patients were treated in accordance with the localizing method -stage II/III. Visual acuity of the master eye was equal 1.0, and of the squinting eye-from 0.3 to 0.8 after...
In general, measurement errors can be divided into three parts with respect to their effect on focus depth of the dot target. (1) Gyroscope north bias: The yaw angle of the platform is measured by a gyroscope, which is an important component of an INS. However, this bias affects the ...
