  • Publication number: 20210091979
    Abstract: Embodiments of the present disclosure provide a method, device, and computer readable medium for channel equalization. The method comprises receiving, at a first device, a first signal from a second device via a plurality of subcarriers over a communication channel; sampling the first signal to obtain sampled symbols; and generating a second signal based on the obtained sampled symbols using a direct association between sampled symbols and payloads, the second signal indicating a payload of the first signal carried on an effective subcarrier of the plurality of subcarriers. Through the use of the direct association between sampled symbols and payloads, it is possible to achieve channel equalization in a less complicated, more reliable, and cost-effective manner, so as to extract the payload in the received signal.

  • Patent number: 9998212
    Abstract: Provided are a method, a system and a node for implementing APS in an OBRing network. The method comprises: a master node and a slave node separately perform optical power monitoring on respective channels, and aggregate monitoring results to the master node; when determining, according to the monitoring results, that a fault occurs, the master node sends a switching operation instruction to the slave node; and the slave node performs a switching operation and enters a protection working state. With the disclosure, a protection switching mechanism is introduced to the OBRing, which implements the processing on fault and ensures the communication quality of the OBRing.

  • Patent number: 9362798
    Abstract: An outer-rotor motor includes a stationary portion, a rotating portion, and a bearing mechanism arranged to support the rotating portion such that the rotating portion is rotatable about a central axis extending in a vertical direction with respect to the stationary portion. The stationary portion includes a stator, a mounting plate, and a circuit board. The rotating portion includes a shaft, a rotor holder, and a rotor magnet. The mounting plate includes a projecting portion arranged to project radially. The outer-rotor-motor further includes a guide structure connected with the projecting portion. The guide structure is arranged to extend axially, radially outside the rotor holder. A leadwire is electrically connected to the circuit board, and is guided along the guide structure. Provision of the guide structure, which is arranged to guide the leadwire radially outwardly of the rotor holder, contributes to preventing a contact between the leadwire and the rotor holder.

  • Patent number: 9071103
    Abstract: A color wheel driving motor includes a magnet arranged radially outward of a rotor holder. The ring-shaped magnet includes n number of N-pole and n number of S-pole and magnetic pole changeover portions arranged between the poles. The magnetic pole changeover portions are arranged at an angular interval of 360°/2n, the n being a positive integer. On an imaginary plane perpendicular to the center axis, a first straight line passing through the center axis and at least one of the 2n magnetic pole changeover portions makes a specified angle ? with respect to a second straight line extending from the center axis toward the ring-shaped magnet. A first mark is arranged in a region of a surface of the ring-shaped magnet where the second straight line overlaps with the ring-shaped magnet, the specified angle ? being equal to or larger than 0° and equal to or smaller than 360°/2n.
