Abstract: A lightweight steel construction includes a plurality of beams and rafters. Each of the beams includes two opposite C-shaped steels. Two ends of the two C-shaped steels are respectively positioned by two first positioning members in a length direction of the C-shaped steels. Several beams can be assembled with each other via the first positioning members to be formed as a crossbeam and a column of a building. Each of the rafters includes a C-shaped steel. Two ends of the C-shaped steel are respectively positioned by two second positioning members in the length direction of the C-shaped steel. Several rafters can be positioned between adjacent beams via the second positioned members to be formed as a floor surface, a wall surface, and a roof of the supporting frame of the building.

Abstract: A method for automatically setting a panel parameter of a display device is provided. The display device includes a controller and a display panel. The method includes steps of: storing a plurality of panel parameters respectively corresponding to different types of panels to a non-volatile memory; detecting a status signal of a predetermined pin, the status signal corresponding to the type of the display panel; selecting one panel parameter from the panel parameters according to the status signal; and generating an output signal according to the selected panel parameter by the controller.

Abstract: A rail assembly is adapted for mounting a data storage device in a computer enclosure. The rail assembly comprises a rail and a conductive fastener attached to the rail for fixing the rail to a data storage device. The rail comprises a body and a latch so connected with the body as to be capable of a flexing movement relative to the body for engaging with a computer enclosure. The body defines a number of pairs of through holes and a first slot. The fastener comprises a pair of tabs for engagingly extending into a selected pair of the through holes of the rail and a pair of posts for extending through the first slot of the rail to securely engaging with the data storage device. The fastener can mount the rail to the data storage device with the rail attached at a number of different positions relative to the data storage device.
