The control module controls the height adjustment mechanism to adjust a relative distance between the coaxial light source and the carrier platform. The inspection device for a sub-element of a reticle pod performs optical inspection on the sub-element of a reticle pod.

Abstract: A high-speed surface inspection system for a reticle pod and method comprises a cabinet, a clamping module, a first inspection device, a second inspection device, and a travel stroke controller. An interior of the cabinet is divided into an automated device area, a first inspection area, and a second inspection area. The travel stroke controller controls the clamping module to reciprocate between the automated device area and the first inspection area so as to transport a first portion of the reticle pod, and controls the clamping module to reciprocate between the automated device area and the second inspection area so as to transport a second portion of the reticle pod. A high-speed surface inspection method for a reticle pod is further provided. The present application solves the issue of an inability for efficient surface inspection of a reticle pod.

Abstract: A gripping mechanism for inspection of a reticle inner pod includes a quadrilateral frame and fourth gripper units. The four gripper units are respectively disposed at four border strips of the quadrilateral frame and are opposite in pairs. Each gripper unit has a body, a first gripping portion and a second gripper portion. The first and second gripping portions are respectively located on different positions of the body. The first gripping portions form a first gripping plane, and the second gripping portions form a second gripping plane. At least two adjacent gripper units have a power member, which is in power connection with the body so as to adjust a distance between two bodies opposite to each other. The gripping mechanism for the inspection of the reticle inner pod is capable of securely gripping the reticle inner pod during transportation or turning of reticles.

Abstract: Exemplary methods, apparatuses, and systems include firmware for the non-volatile storage device, during boot up, dynamically allocating volatile memory to a plurality of storage management components. The allocation includes detecting an indicator of a total amount of volatile memory to be allocated to the storage management components. The firmware maps the indicator to a first amount of volatile memory to allocate to a first set of one or more components and allocates the first amount of the volatile memory to the first set of components. The firmware allocates remaining volatile memory to a flash translation layer.

Abstract: Methods and systems configured to increment one or more counters, including read command total, write command total, total blocks written and read, and low read or write queue depth, when a read or write command is received. When a request for a total device busy time is received, a total device busy time is determined and provided using one or more of the counters and one or more corresponding timing factors.

Abstract: A stackable computer housing assembly includes at least two computer housings. Each of the computer housing has a frame body, two first sliding rails and two second sliding rails. The frame body has a top portion and a bottom portion. The two first sliding rails are assembled at the top portion of the frame body, and the two second sliding rails are assembled at the bottom portion of the frame body. Two of the computer housings slidably engage each other through the two first sliding rails and the two second sliding rails, such that the two computer housings are stackingly coupled. The first sliding rail, the second sliding rail and the frame body are independent pieces. The first sliding rail and the second sliding rail fixed to the frame body by assembly, to facilitate application on different computer housings, have preferred compatibility and reduced production cost.

Abstract: A variably threaded screw has a first end and a second end, the first end of the shaft terminating in a tip and the second end having a widened head thereon. A first helical thread portion is located on the shaft adjacent the widened head. A second helical thread portion is located on the shaft adjacent the tip of the shaft.
