Abstract: The present invention provides an energy delivery device for use with a medical treatment system for the more efficacious treatment of patients during laser surgery which limits the number of uses or prevents reuse of the energy delivery device after a certain threshold limit has been reached. The energy delivery device comprises a diffusing optical fiber and a memory device having data programmed therein and being operatively connected to an energy generator the optical fiber includes a temperature sensor for generating a temperature signal in a closed loop manner. The data stored in the memory device includes a multiplicity of use parameters, usage limits, usage counts, and count limits all relating to the properties of the medical treatment system. The use parameters may include an elapsed time, a total treatment time, and a number of treatment sites.

Abstract: In a device and a method for a tree harvester head for trimming tree trunks, the device includes a frame (1) supporting feed rollers (2), one or more trimming knives (4) that pivot towards and away from the tree trunk, as well as a trimming knife (6) permanently fixed to the frame (1) and with a radius of curvature that is essentially equivalent to the radii of curvature of the pivoting trimming knives (4).

Abstract: A tree delimbing apparatus has a boom with a delimbing head and a set of traction arms to drive the log through the delimbing head. The boom is utilized to grasp the log and allow the traction arms to grip it, following which the traction arms then drive the log through the delimbing head to remove the branches.
