Patent number: 11414991Abstract: Provided are a system and a method for monitoring bearing compression rate of a filler in a coal mine gob area. An ground information processing system, a vibration source control system, and a monitoring system are arranged on the ground according to a buried depth of the filler in the gob area. The vibration source control system generates vibration, and transmits a signal to the filler. The monitoring system on the ground receives different reflected waves according to different elasticities of the fillers under different compaction degrees. Final data is transmitted to the ground information processing system for data processing. The monitoring of the filler starts when the filler is filled in the gob area; the filler is gradually compacted. The filler is monitored until the thickness of the filler does not change. Finally, a bearing compression rate formula is utilized to calculate the bearing compression rate of the filler.Type: GrantFiled: June 24, 2019Date of Patent: August 16, 2022Assignee: CHINA UNIVERSITY OF MINING AND TECHNOLOGYInventors: Jixiong Zhang, Yang Ju, A.

Patent number: 11296810Abstract: An optical circuit includes: a multicast-and-select (MCS) switch and multiple optical selective devices coupled to output ports of the MCS switch. The selective devices may select a single optical channel by blocking some of wavelengths of light passing therethrough and passing at least one other wavelength. The selective devices may be wave blockers or tunable optical filters. The optical circuit further includes an optical amplifying array, wherein each amplifier has an input port optically coupled to one of the selective devices. At least some of the amplifiers have pump light ports for receiving at least a portion of the pump light from one or more laser pumps or from another of the optical amplifiers, wherein the pumps are capable of providing pump light sufficient to fully saturate all of the rare earth doped optical fibers in the array.Type: GrantFiled: December 27, 2017Date of Patent: April 5, 2022Assignee: Accelink Technologies Co., Ltd.Inventors: Alan Solheim, Qinlian Bu, Weiqing Zhang, Chengpeng Fu, Lijie Qiao
