Abstract: A method of using a conveyor system comprising capturing, with a first camera of the conveyor system, a first image of a server tray and a plurality of hard disks received along a first conveyor belt of the conveyor system, checking, with one or more processors of the conveyor system, a first serial number associated with the server tray and a second set of serial numbers associated with the plurality of hard disks against a reference list of serial numbers, capturing, with a second camera of the conveyor system, a second image of the server tray and the plurality of hard disks, and verifying an integrity status of the server tray and plurality of hard disks based on the second image.

Abstract: A method for expanding human corneal endothelial cells includes: (a) providing an amniotic membrane with or without amniotic cells, wherein the amniotic membrane has an extracellular matrix; (b) placing onto the amniotic membrane, a sheet of endothelial layer, or a cell suspension including human corneal endothelial stem cells; and (c) culturing the corneal endothelial cells on the amniotic membrane for a duration sufficient for the corneal endothelial stem cells to expand to an appropriate area. The invention also relates to a method for creating a surgical graft for a recipient site of a patient using the method for expanding human corneal endothelial cells, and the surgical graft prepared therefrom.

Abstract: A lamp having a planar light-emitting source includes a light-guiding structure, a light-emitting portion, and a shading supporting seat. The point-shaped lighting units of the light-emitting portion emit the point-shaped light beams toward the side plane of the light-guiding structure. Then, these beams enter the light-guiding structure. After turning approximately 90 degrees, a uniformly distributed planar light generated from the light-emitting plane of the light-guiding structure. So, a planar light source is obtained. In this invention, it has a planar light-emitting function with better lighting efficiency. The planar lighting is evenly distributed without shadow. Its energy consumption and heat generation are low. The product's life is prolonged. Its volume is small and it is portable.
