    • A secondary power source system for a communication device includes a charging unit configured to receive a primary power input and restrict a current used for charging to a predetermined amount. The current is part of a first output of the charging unit. The system further includes a storage unit including a device that stores electrical energy, the storage unit configured to receive the first output from the charging unit with restricted current and generate a second output, a regulating unit configured to receive the second output from the storage unit and generate a third output, a selector unit configured to perform a logical OR operation with the primary power input, the first output from the charging unit and third output from the regulating unit, and to generate a fourth output, and a shutdown unit configured to shutdown operation of the secondary power system when the storage unit has been expended.

    • A refrigerant recovery unit includes a refrigerant storage unit, a refrigerant circuit, a processor, and a memory. The refrigerant storage unit is configured to store a refrigerant. The refrigerant circuit is in fluid connection with refrigeration system. The refrigerant circuit is configured to recover refrigerant from the refrigeration system and recharge the refrigeration system with the refrigerant. The processor is configured to control the refrigerant recovery unit and the processor is configured to control a fan. The fan is configured to provide a flow of air to the refrigeration system. The memory is to store diagnostic software and operating software to operate the refrigerant recovery unit.
    • 制冷剂回收单元包括制冷剂储存单元,制冷剂回路,处理器和存储器。 制冷剂储存单元构造成储存制冷剂。 制冷剂回路与制冷系统流体连接。 制冷剂回路被构造成从制冷系统回收制冷剂并且用制冷剂对制冷系统再充电。 处理器被配置为控制制冷剂回收单元,并且处理器被配置为控制风扇。 风扇构造成为制冷系统提供空气流。 存储器是存储诊断软件和操作软件以操作制冷剂回收单元。
