Abstract: A battery charge and discharge protection method is to be implemented by a battery charge and discharge protection device, and controls power transfer to a load device based on results of detections of whether each of two batteries is correctly installed or reversely installed and whether each of the batteries is rechargeable or non-rechargeable. When any one of the batteries is reversely installed, power transfer from the batteries to the load device is disabled. When both of the batteries are correctly installed, the batteries are connected in parallel if they are both rechargeable and in series if they are both non-rechargeable, and power transfer from the batteries to the load device is enabled.

Abstract: A wireless microphone includes a tubular housing having top and bottom open ends. The housing has an outer surrounding wall and an inner partition wall. The inner partition wall cooperates with an upper portion of the outer surrounding wall so as to define a battery-receiving space. A battery module is received in the battery-receiving space. A head unit is mounted on the top open end of the housing, and covers the battery module. A positioning unit is disposed at an outer surrounding surface of the battery module and an inner surrounding surface of the outer surrounding wall of the housing for positioning the battery module in the battery-receiving space.

Abstract: The invention discloses an organic light-emitting display panel, which includes a substrate, an electrode layer, a light-emitting layer, upper conductors and assistant electrodes. The electrode layer is disposed on the substrate. The light-emitting layer is disposed on the electrode layer. The light-emitting layer includes organic light-emitting units and isolation units. The organic light-emitting units are separately disposed on the electrode layer. The isolation units are disposed between the organic light-emitting units. The upper conductors are disposed on the light-emitting layer. The assistant electrodes are respectively disposed on the isolation units. Each assistant electrode is electrically connected with one of the upper conductors, so as to reduce the equivalent resistance of the upper conductor with the assistant electrode.
