  • Patent number: 11019194
    Abstract: A non-transitory computer-readable storage medium includes instructions for commissioning a power meter that has a Bluetooth Low Energy (BLE) communication capability, the instructions, when executed by one or more processors of a mobile device, cause the mobile device to discover the presence of the power meter by recognizing a signal produced by the Bluetooth Low Energy (BLE) communication capability of the power meter and receive a unique identifier for the power meter. When the received unique identifier matches a unique identifier stored by the power meter, the mobile device will establish a communication link between the mobile device and the power meter using the Bluetooth Low Energy (BLE) communication capability of the power meter and will transmit one or more commissioning parameters to the power meter via the established communication link between the mobile device and the power meter.

  • Publication number: 20200257749
    Abstract: An objective of the present application is to provide a method and a device for friend recommendation. The present application implements reverse friend recommendation according to a contact list by the following steps: obtaining user information of a first user and indication information of a second user; determining the second user according to the indication information of the second user; sending the user information of the first user to a recommended user list of the second user. Further, information on a contact list of the first user is compared with information on a friend list of the first user, and a contact not in the friend list but in the contact list is identified as the second user, so that recommending friends repeatedly which causes a waste of system resources is avoided.

  • Patent number: 10594207
    Abstract: In many power electronics systems, there is an intermediate DC-link stage for facilitating the power processing of different sources to their loads. A device called a plug-and-play ripple pacifier (RP) directly plugged into the DC-link, and actively removes undesired DC-link ripple, thereby eliminating the reliance on electrolytes capacitors for stabilizing the system and remove ripple. Importantly, the use of this device is non-invasive to the operation of its host systems, and requires no modification of existing hardware. It is suitable for the protection of DC utilities/systems and can also be used as a direct replacement of ripple-canceling E-Caps in power converters device.

  • Patent number: 10212770
    Abstract: A single-stage AC-DC single-inductor multiple-output (SIMO) LED driver uses a single inductor (L) to drive multiple independent LED strings (341-34n) with Power Factor Correction (PFC). The driver uses a diode bridge (20) to achieve initial AC to DC conversion. The output of the bridge (20) is provided to a buck converter whose output is shared with multiple LED strings by a time division multiplex circuit. Feedback is used to separately control the current supplied to each LED string by using a separate reference for each string and controlling the width of the current pulse provided to a string. Current balancing in every LED string can be achieved with the same voltage reference without the need for additional circuitry.
