Abstract: An integrated device for rapid detection of SARS-CoV-2 is disclosed. The integrated device includes a front-end system, a back-end system, and a microfluidic channel. The front-end system includes a detection region and a control region. The detection region and the control region have similar structures, each including an interdigital electrode and a graphene film. The microfluidic channel is arranged to cover the detection region so as to allow the interdigital electrode of the detection region to be exposed to the breath sample. The graphene film of the detection region has a surface resistance higher than that of the graphene film of the control region when the detection region is exposed to a selected virus. The back-end system is configured to detect and compare the surface resistance of the graphene films of the detection region and the control region for determining whether the selected virus is present in the breath sample.

Abstract: A cap has a body with an opening defined in one end of the body. A floor is formed in the opening and is parallel to an end wall of the body defining the opening. An annular flange perpendicularly extends from the floor in the opening. With a specific mold and a specific process, the cap can be formed with a die casting process without draft allowance. The process for forming the cap is simple and the cost for manufacturing the cap is low.

Abstract: A strip safe-releasing device using ratchets is disclosed. A body and handle is connected by a shaft. Since the stopping piece of the body with respect to the handle is installed with a sliding groove. Thereby, the handle can be rotated so that the stopping piece is inserted into the sliding groove, then the convex portion ejects the buckle to release the ratchet. Thereby, the shaft is driven by the reaction force of the strip so as to release the tension of the strip. Since the rotation of the ratchet will synchronously drive the convex portion of the handle not to eject the buckle. Thus, the buckle moves forwards to engage the ratchet and confine the rotation of the shaft. Therefore, each time the shaft rotate through a few angles, the tension releases a little. Therefore, the tension of the strip is released step by step in a safe way.

Abstract: A power-saving infrared-detecting receiving system composed of a micro-controller serving as a main control unit of the receiving system, an infrared module powered through the micro-controller for receiving a modulated infrared signal emitted by a remote controller used together with the receiving system, and an ultra-low power-consuming and independently powered predetector For detecting a low-frequency infrared front guide signal emitted by the remote controller. The receiving system is normally in a standby state in which only a very low power is consumed by the predetector to detect the infrared front guide signal emitted by the remote control for triggering the micro-controller. When the micro-controller is triggered, the receiving system enters into an operational state and sufficient current is supplied to the infrared module for it to receive a complete modulated infrared signal emitted by the remote controller.
