Abstract: Embodiments of this application disclose a method and a device therefor, applied to a scenario of Ethernet packet transmission. In an example method, a first device receives a first packet. Load data in the first packet includes padding redundant data. The first device deletes the padding redundant data. The first device generates a second packet. Load data in the second packet is payload data obtained after the padding redundant data is deleted from the first packet. The first device sends the second packet to a second device.

Abstract: A TOF sensor module is disclosed. The TOF sensor module includes a light source, a beam adjustment assembly, and a detection assembly. The light source is configured to emit m first beams at each of M moments, and transmit the m first beams to the beam adjustment assembly. The beam adjustment assembly is configured to: after adjusting the received m first beams into S second beams, project the S second beams to S regions of a detection surface, where M projection points that are in a same region of the detection surface and to which projection is performed at the M moments respectively have different locations. The detection assembly is configured to receive S optical echo signals from the detection surface at each of the M moments, and convert the S optical echo signals into S electrical echo signals for storage at each moment.

Abstract: This application provides example data packet transmission methods and example communications apparatuses. One example method includes receiving a data packet, where the data packet is in an undelivered state. The data packet can then be delivered during running of a reordering timer upon an arrival of a first delay cut-off moment corresponding to the data packet or an arrival of a second delay cut-off moment of an additional data packet before the data packet in a reordering window.
