Abstract: An instant osteoarthritis test paper is used to detect a urine sample and comprises a substrate, a test result layer arranged on the substrate, a water absorption layer connecting with the substrate and partially covering the test result layer, an antibody release layer connecting with the substrate and partially covering the test result layer, and a sample reception layer connecting with the substrate and partially covering the antibody release layer. The test result layer includes a result indication zone and a control zone. The antibody release layer includes a plurality of test complexes each containing a colloidal gold and a plurality of polyclonal antibodies to COMP binding to the colloidal gold. The instant osteoarthritis test paper provides a non-invasive inspection method, and thereby favors early detection and therapy of degeneration of articular cartilage to slow down the deterioration speed of the disease.

Abstract: In a method of recording and outputting messages using an electronic device, a message is recorded using an input device and is stored into a storage device of the electronic device. When a person appears within a detection range of a detection device of the electronic device, the detection device identifies the person, and the message corresponding to the identified person is outputted using an output device of the electronic device.

Abstract: A stove and a method for preventing a cooked material from being burnt dry are provided. The stove includes a stove body for heating the cooked material, a weighing unit for generating a weighing signal of the cooked material, a monitoring unit for judging whether the user is managing the cooked material, and a computing unit. The weighing signal is changed with time. A plurality of weighing signal change amounts respectively generated within a plurality of time intervals are calculate by the computing unit. According to the weighing signal change amounts, the heat source of the stove body is adjusted. Consequently, the function of preventing the cooked material from being burnt dry will be achieved.

Abstract: A charge controller has a printed circuit board (PCB), a first transmission interface, a second transmission interface, and a recognition integrated circuit (IC). The recognition IC of the charge controller recognizes a type of a second electronic device coupled to the second transmission interface, so that a power source of a first electronic device coupled to the first transmission interface in the charge controller is charged in the second electronic device. A portable device applying the charge controller is also described.
