Abstract: Some embodiments of the present disclosure relate to a processing tool. The tool includes a housing enclosing a processing chamber, and an input/output port configured to pass a wafer through the housing into and out of the processing chamber. A back-side macro-inspection system is arranged within the processing chamber and is configured to image a back side of the wafer. A front-side macro-inspection system is arranged within the processing chamber and is configured to image a front side of the wafer according to a first image resolution. A front-side micro-inspection system is arranged within the processing chamber and is configured to image the front side of the wafer according to a second image resolution which is higher than the first image resolution.

Abstract: A free walking training machine includes a chassis having a left supporting frame and a right supporting frame, a left swing arm having a left axial portion extending laterally, a right swing arm having a right axial portion extending laterally, a left lifting mechanism, a right lifting mechanism, a first linking unit, and a second linking unit. The left lifting mechanism makes the left swing arm move upward and downward relative to the left supporting frame. The right lifting mechanism makes the right swing arm move upward and downward relative to the right supporting frame. The first and second linking mechanisms are connected with the left and right swing arms for enabling the left and right axial portions and the left and right swing arms to make coordinated movement and move in opposite directions, respectively. The first and second linking mechanisms are operable independently.

Abstract: An elliptical exercise apparatus includes a base frame with two supporting frames, two swing sleeves each pivotally connected with one supporting frame, two sliding arms each having a top portion slidably inserted through one swing sleeve and a bottom portion extending transversely inwardly and coupled with a treadle, two swing arms each having an end pivotally coupled with the base frame, and two sliding sleeves each axially slidably sleeved onto one swing arm and pivotally connected with the bottom portion of one sliding arm through a pivot. A rotational shaft is transversely and rotationally coupled with the base frame. Two links each have an end vertically coupled with one of two ends of the rotational shaft, and an opposite end pivotally connected with a lower portion of one of the sliding sleeves.

Abstract: A free walking training machine includes a chassis having a left supporting frame and a right supporting frame, a left swing arm having a left axial portion extending sidewards, a right swing arm having a right axial portion extending sidewards, a left lifting mechanism, a right lifting mechanism, a first linking unit, and a second linking unit. The left lifting mechanism makes the left swing arm move upward and downward relative to the left supporting frame. The right lifting mechanism makes the right swing arm move upward and downward relative to the right supporting frame. The first and second linking mechanisms are connected between the left and right swing arms for enabling the left and right axial portions and the left and right swing arms to make linking movement and move toward contrary directions, respectively. The first and second linking mechanisms are operable independently.
