Patent number: 10038470Abstract: The invention relates to network communication safety, and provides an intelligent socket and an intelligent system. The intelligent socket includes a first control module, and a second control module connected with the first control module. The first control module is configured to receive a data signal, transcode the received data signal, and transmit the transcoded data signal. The second control module is configured to receive a data signal, modulate the data signal, and transmit the modulated data signal. The intelligent socket is configured to achieve communication between a control terminal and a controlled terminal and achieve data transmission, demodulation, transcoding and other functions, thereby reducing the burden on the control terminal, improving the intelligence level of the intelligent socket to a certain extent, and bringing more convenience to users.Type: GrantFiled: November 13, 2017Date of Patent: July 31, 2018Assignee: Minwa Auto-Protection (Smart Plug) Technology Co. LimitedInventor: Hak Wah Lau

Patent number: 9882411Abstract: A lithium-ion battery includes a lithium-ion cell, a positive electrode terminal, a positive/negative electrode insulation sheet, a connector and a housing used as a negative electrode. The lithium-ion cell is arranged in the housing, the connector is arranged between the lithium-ion cell and the housing. The positive electrode terminal is installed on one end of the lithium ion cell. A circuit board is arranged between the battery positive/negative electrode and the lithium-ion cell. A voltage/current control and overcharge/over-discharge protection circuit is integrated on the circuit board. The voltage/current control and overcharge/over-discharge protection circuit can adjust the voltage of the lithium-ion battery to be a voltage of 1.5V/1.2V. The shape and size of the housing can be designed to be any shapes to replace traditional dry batteries according to requirements. The lithium-ion battery can be designed to be using the same port to do the discharging and charging work.Type: GrantFiled: June 22, 2016Date of Patent: January 30, 2018Assignee: MINWA ENERGY LITHIUM BATTERY TECHNOLOGY CO.

Patent number: 9235224Abstract: A voltage regulating device includes a power supply adapter, a voltage and current signal processing module, a control module, and a voltage regulating module. The power supply adapter supplies voltage to an electronic device. The voltage and current signal processing module detects the current and voltage supplied by the power supply adapter, and calculated the desired voltage adapted for the electronic device according to the detected current and voltage and a preset voltage for the electronic device. The control module generates a control signal according to the calculated desired voltage. The voltage regulating module regulates the voltage supplied by the power supply adapter according to the control signal, to cause the voltage supplied by the power supply adapter to adapt for the electronic device. As a result, the voltage regulating device can regulate the voltage supplied by the power supply adapter to adapt for the electronic device, which can be used conveniently.Type: GrantFiled: August 6, 2013Date of Patent: January 12, 2016Assignee: MINWA ENERGY AUTO SWITCH TECHNOLOGY COMPANY LIMITEDInventor: Hak Wah Lau
