Abstract: A location-based message processing system may include one or more internet of things (IoT) devices, a cloud processing unit, a message exchanging system (MXS), and one or more mobile terminals, wherein the IoT device is configured to transmitted location-based information to the cloud processing unit, which is configured to save, maintain and analyze the location-based information, and transmit customized information for each user to the MXS, and the MXS is configured to deliver such information to an application software (APP) of the mobile terminal of each user. In one embodiment, the IoT devices in the present invention are wireless charging devices including but not limited to, wireless chargers, charging tables, wearable charging devices, portable/non-portable chargers. In another embodiment, the cloud processing unit may include at least a processor and memory device to process, save and maintain data transmitted from the IoT devices.

Abstract: A wireless charging receiver may include a main body, a connecter to electrically connect to batteries or other electronic devices, a receiving unit to pick and receive wireless power transmission, and a wireless charging module to convert the power into an electrical current. In one embodiment, a coil may be included in the receiving unit to realize the wireless charging. In another embodiment, the magnetic strip can be used to attach to a surface of other devices to secure the wireless charging receiver thereon. When a wireless power transmission comes in, the receiving unit can realize the wireless charging and pick it up from an electromagnetic field, and the wireless charging module is configured to convert it into an electric current that can be stored in the rechargeable battery through the electrical connection between the receiver and the battery.

Abstract: A remote wireless charging device may include a power source, an antenna, a wireless charging transmitter to receive electrical power from the power source, and a power control circuit to manage usage of the battery. In one embodiment, the wireless charging transmitter receives the input energy from the power source and generates the radiated energy field, which is sent out through the antenna. A receiver of a mobile device, separated from the transmitter within a predetermined distance, is configured to receive and generate an output power for the mobile device. It is noted that a mutual resonant frequency exists between the transmitter and the mobile device, and the energy loss during the energy transmission can be minimized when the transmitter and the receiver both reach the mutual resonant frequency.

Abstract: A portable wireless charging apparatus may include a battery; a coil configured to detect whether a receiver of a first mobile device is nearby and to emit electrical magnetic pulses to realize the wireless charging; a wireless charging modulator configured to take direct current from the battery, transform the direct current into alternate current pulses and send the alternate current pulses to the coil; and a power control circuit to manage usage of the battery. In an exemplary embodiment, the power control circuit has a power managing unit and a detecting unit, said power managing unit configured to raise a battery level of the battery to a predetermined charging level, and said detecting unit continuously monitoring battery levels of the battery and a first battery in the first mobile device respectively to determine whether to terminate the wireless charging of the first mobile device.
