A track for an adjustable blind assembly comprises a base and a slot. The motor controller outputs an excitation signal to the resolver and an AD converter thereof alternately applies analoguedigital conversion to a sine wave signal and a cosine wave signal outputted from the resolver so that a rotation position of the motor is calculated. The recent patient activities are non-claim-based activities from a number of healthcare organizations received from the electronic devices associated with the plurality healthcare organizations. The method comprises providing a such drilling assembly, placing a drill pipe onto the drilling assembly, moving the thrust frame to a desired drilling angle, moving the rotary and carriage assembly into direct contact with the drill pipe, applying rotational, thrust and pull-back forces to the drill pipe, drilling the pipe into the drilling surface and controlling the load on the drill bit.
