Abstract: An apparatus comprises a first mirror; a second mirror; a modulation layer positioned between the first mirror and the second mirror and comprising a plurality of modulation regions; a diffraction layer positioned between the modulation layer and the second mirror, and an input port admitting a light beam into the apparatus. The light beam passes through the diffraction layer and is modulated by the modulation layer to create a first modulated beam before being reflected by the first mirror, the first mirror reflecting the first modulated beam toward the second mirror, the second mirror reflecting the first modulated beam toward the modulation layer to be modulated for at least a second time.

Abstract: A scheduling method, including: listening to, by a station, a first beacon frame containing a DTIM message used for indicating a beacon interval allocated for each group of stations within a current scheduling period; determining the beacon interval allocated for the station within the current scheduling period according to the DTIM message contained in the first beacon frame; listening to, by the station, within the beacon interval allocated for the station, a second beacon frame containing scheduling information of the current beacon interval used for indicating a time period allocated to each group of stations for data transmission within the current beacon interval; when data transmission is required, transmitting, by the station, data within the time period allocated to the group of the station according to indication of the scheduling information. The present invention improves utilization of time periods, saves time resources and enhances transmission efficiency.

Abstract: A sensor includes: two friction layers and at least one electrode layer. The two friction layers are respectively made of materials with different electron gain and loss capabilities, and a surface of at least one friction layer includes a multi-level micro-nano structure, so that when there is pressure, equal-quantity and opposite net charges corresponding to the applied pressure are induced on the two friction layers. The multi-level micro-nano structure includes micro-nano columnar structures with at least two different heights. The electrode layer is configured to generate a current based on the net charges. The multi-level structure with different heights is designed.
