Abstract: Examples relate to communicating synchronization information from a satellite to a power supply device to enable time synchronization between the satellite and the power supply device. The power supply device includes a port to receive, from a modulator, a modulated current corresponding to a power consumption across a dummy load, where a level pattern of the modulated current indicates the synchronization information received from the satellite. The power supply device includes a power consumption analyzer configured to receive a modulated voltage, across a shunt resistor, corresponding to the modulated current and recover, from the modulated voltage, the synchronization information.

Abstract: Embodiments of the present disclosure relate to a power supply device, an electronic system and a method. The electronic system comprises an electronic device and the power supply device transmitting synchronization information from a satellite to the electronic system. The power supply device comprises a first modulator configured to receive a signal from a satellite and to generate a first modulated supply voltage, a level pattern of the first modulated supply voltage indicating synchronization information included in the satellite signal; and a first transformer configured to provide the first modulated supply voltage to an electronic device to enable a synchronization between the satellite and the electronic device based on the synchronization information. The electronic device demodulates the first modulated supply voltage to determine the synchronization information for synchronizing with the satellite. By using the embodiments of the disclosure, cost for manufacturing the electronic devices can be significantly reduced.

Abstract: A power-over-Ethernet (PoE) powered device (PD) comprises a PoE interface to receive a connector of an ethernet cable to connect the PD to a PoE power sourcing equipment (PSE). The PD comprises a first power line connected to the PoE interface to receive PoE power from the PSE in a connected state of the PD to the PSE. The PD also comprises a rectifier comprising a first input connected to the first power line, a first output connected to a first terminal of a PD chip, and a first rectifying element connected between the first input and first output. The PD further comprises a first capacitor connected in parallel to the first rectifying element between the first input and the first output. AC noise appearing on the first power line is bypassed around the first rectifying element via the first capacitor.

Abstract: In embodiments of the present disclosure, a method is provided for managing an AP position for an access point. In the method, a magnetic distribution map is obtained for an indoor area, the magnetic distribution map representing a plurality of reference magnetic values that are collected at a plurality of reference positions in the indoor area. A plurality of magnetic measurements are received, here the plurality of magnetic measurements are respectively collected at a plurality of access point (AP) positions at which a plurality of APs are deployed within the indoor area, and the plurality of AP positions are unknown. The plurality of AP positions are mapped to a portion of the plurality of reference positions based on the plurality of magnetic measurements and the plurality of reference magnetic values. The plurality of AP positions are determined based on the portion of the plurality of reference positions. Therefore, AP positions may be determined accurately and effectively in an indoor environment.
