Abstract: A device casing includes a casing body and a detachable bracket. The casing body has first and second supporting frames opposite to each other, and first and second guiding slots formed on the first supporting frame. The first guiding slot has a first open end and a first closed end. The second guiding slot has a second open end and a second closed end. The detachable bracket is detachably disposed between the first and second supporting frames and has first and second sliding posts. The first sliding post is rotatably disposed at the first closed end. The second sliding post is slidably disposed at the second closed end. By the structural constraint between the first and second guiding slots and the first and second sliding posts respectively, the detachable bracket can stably rotate relative to the casing body and can be installed onto the casing body easily.

Abstract: A chassis includes a bottom plate, a fastener and a supporting component. The bottom plate includes a screw hole. The fastener comprises a threaded portion and a smooth portion that are connected to each other, and the threaded portion is configured to be screwed into the screw hole. The supporting component includes a through hole. The smooth portion of the fastener is configured to be disposed through the through hole so that the supporting component is rotatably disposed on the bottom plate so as to include a supporting position and a stored position. The supporting component is integrated.

Abstract: This disclosure relates to a computer case configured to fix an interface card. The computer case includes a main body, a plurality of mount brackets and a framework. The main body includes a first hole and a plurality of second holes. The plurality of second holes are located at a side of the first hole. The plurality of mount brackets are located at the first hole. The framework is conductive. The framework includes a plurality of protrusion portions and a plurality of main portions. The plurality of protrusion portions are connected to the plurality of main portions and are respectively inserted in the plurality of second holes. The framework is disposed on the main body via the plurality of protrusion portions. The plurality of main portions are respectively in contact with the plurality of mount brackets.

Abstract: A vehicle safety method includes steps: monitoring a face state of a driver and determining whether the face state satisfies a tired state or not; sensing a physiological state of the driver and determining whether the physiological state satisfies a conscious state or not; sending a warning query when the face state satisfies the fired state and the physiological state satisfies the conscious state; determining whether a response corresponding to the warning query is received or not; and activating a vehicle safety mechanism if the response corresponding to the warning query is not received.
