Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: The present disclosure discloses a method for recycling all types of lithium batteries. First, the lithium battery waste is acid-leached to obtain a solution containing most of metal ions. After filtering, the solution is separated from the remaining solids, and then the obtained solution is subjected to separate precipitation many times. After separately adjusting the pH value of the solution many times, adding precipitants with a high selectivity ratio, and matching with filtration and separation reaction, all ions in the lithium battery waste are sequentially precipitated in forms of iron phosphate (FePO4), aluminum hydroxide (Al(OH)3), manganese oxide (MnO2), dicobalt trioxide (cobalt oxide, Co2O3), nickel hydroxide (Ni(OH)2), and lithium carbonate (Li2CO3).

Abstract: The battery charging device contains at least a first charging battery, at least a second charging battery, and a control module parallel-connected to the first and second charging batteries. The control module contains a control unit, a detection element, and a switch element. The control unit is configured with a current threshold. The detection element detects a total current from the first and second charging batteries. The control unit triggers the switch element to disconnect the first charging battery when the total current is greater than the current threshold. The control unit then triggers the switch element to reconnect the first charging battery when the total current drops below the current threshold.

Abstract: A multifunctional electrical power output protection device includes a protection device having a circuit board. The circuit board is mounted in a receiving space of the protection device and includes an input port, an output port, a switching element, a detection element, and a manually-operating overriding device. The manually-operating overriding device is electrically connected to an end of the detection element. The switching element has an end electrically connected to the input port and an opposite end electrically connected to the output port. The detection element has an end electrically connected to the input port and an opposite end electrically connected to the output port. The switching element and the detection element that are connectable to an external power supply respectively provide an effect of preventing backward charging induced by a reverse electrical current and effects of over-loading interruption and current-limiting protection.

Abstract: The portable power supply contains a circuit unit and a rechargeable battery. The circuit unit contains a conversion circuit, an AC output port, a DC input/output port, and a coupling port. The rechargeable battery is coupled to the coupling port. The DC electricity stored in the rechargeable battery is delivered to the circuit unit through the coupling port, and then to a first branch and a second branch. Following the first branch, the DC electricity is transformed a pre-determined AC voltage by the conversion circuit, and the AC voltage is delivered to an external electronic device through the AC output port. Following the second branch, the DC electricity is directly delivered to another external electronic device through the DC input/output port. Without connecting the external electronic device, the DC input/output port is capable of connecting to an external DC power source for charging the rechargeable battery.
