The test device may comprise a wire spool rotatably coupled to the connector and a cable configured to wind on the wire spool. According to some examples, the cable comprises a test end located on a first end of the wire spool and buried in the goaf. The cable may comprise an output end located on a second end of the wire spool, the second end opposite the first end.

Abstract: The present disclosure includes a method of testing for gas and temperature distribution in a goaf, wherein the test device comprises a cable coupled to a cable dragging machine, the cable including a test end configured to be buried in the goaf; a gas temperature tester configured to test a gas for composition and temperature; and a gas pump configured to continuously pump gas from the test end and transmit it to the gas temperature tester. In some examples, the method comprises placing the test end of the cable in the goaf. According to some examples, the method comprises starting the cable dragging machine and starting the gas pump simultaneously with starting the cable dragging machine. The method may comprise withdrawing the cable, via the cable dragging machine, at a constant speed and analyzing, via the gas temperature tester, the composition and temperature of the gas.

Abstract: An integrated photovoltaic cable having a connecting terminal and a housing injection-molded on the connecting terminal. The connecting terminal has a connecting sheet, a through hole, and a plurality of U-shape groove sheets. Exposed conductors obtained by peeling front ends of the photovoltaic cable are respectively placed into corresponding U-shape groove sheets and crimped by a crimping plier. A manufacturing method for manufacturing the integrated photovoltaic cable includes three steps of manufacturing a connecting terminal, crimping photovoltaic wires, and injection molding a housing. An improvement of the cable connecting structure simplifies the production, improves the connecting quality, and reduces a volume of an adapter. The conductor end and the U-shape groove are firmly and conveniently connected to ensure the connection quality, reduce a contact resistance of a connecting wire, and cause a smaller volume of the adapter.

Abstract: The invention discloses an oil-free additive for hair and scalp conditioning, which includes the following ingredients in percentage: 50% pure water, 5% sodium stearoyl lactylate, 10% vitamin E, 10% histidine, 1.5% anhydroxylitol, 3.5% hydrolyzed wheat protein, 7% allantoin, 5% hydrolyzed albumen and 8% carnosine. The invention has following characteristics: 1. It is the first oil-free formula in the field of hair care, so related products produced with the additive will not block hair follicles on scalps, thus leaving no residue and bringing no burden to hair care; 2. It can effectively reduce chemical damages occurred during hair perming and dyeing, and neutralize chemical residue; 3. Being non-irritating and corrosion preventing, it neutralizes residual calcium compounds in the hair, calcium carbonate and magnesium carbonate, thereby inhibiting hair splitting effectively; 4.

Abstract: An illumination unit for emitting light along an optic axis for a projection system includes an LED die and a collimator lens. The collimator lens includes a central part and a peripheral part. The central part has a first light transmission surface and a second light transmission surface opposite to the first light transmission surface. The peripheral part which is around the central part has an inner refraction wall coupled to the first light transmission surface to form a hollow for situating the LED die, an outer reflection wall opposite to the inner refraction wall, and a refraction surface connecting to the second light transmission surface and the outer reflection wall. Both the central part and the peripheral part of the collimator lens are rotationally asymmetrical corresponding to the optic axis.
