Abstract: A charge/discharge circuit includes a power supply module, a switch module, an energy storage module, and a charge-discharge switching module connected in parallel. A first terminal of the energy storage module is connected to the switch module, and a second terminal of the energy storage module is connected to the charge-discharge switching module. The switch module and the charge-discharge switching module are configured to perform an action in response to a charge/discharge enable signal to produce an alternating current in the charge/discharge circuit. A waveform of the alternating current includes at least one of a triangular waveform, a quasi-triangular waveform, a sinusoidal waveform, or a quasi-sinusoidal waveform.

Abstract: The present disclosure provides application of a compound in conformity with a general formula I and an isomer or pharmaceutically acceptable salt thereof to preparation of a medicinal composition for treating or preventing a high altitude disease. The high altitude disease is selected from an acute high altitude disease and a chronic high altitude disease generated in a high altitude environment with an altitude of 2,000 m or above.

Abstract: An intelligent diaper includes an inner layer configured to be substantially liquid-pervious; a transparent outer layer configured to be substantially liquid-impervious; a middle layer disposed between the inner layer and the transparent outer layer and configured to absorb liquid from a diaper wearer's body; a core member disposed between the transparent outer layer and the middle layer, and the core member including an identification zone having a 2D barcode, a color calibration zone, and a test zone having two spaced test paper strips; urine indication strips disposed between the transparent outer layer and the middle layer and being adjacent to the core member; a negative comparison zone having two spaced negative color comparison cards; and a positive comparison zone having two spaced positive color comparison cards. Color of the urine indication strips changes in response to expelled waste.
