Publication number: 20220233763Abstract: Peristaltic pumps are described herein. In certain embodiments, a peristaltic pump includes a plunger, a first biasing member, and a second biasing member. The plunger is movable to selectively engage a pumping volume of a tubing segment to expand the pumping volume to draw fluid flow into the pumping volume and to contract the pumping volume to conduct fluid flow from the pumping volume. The first biasing member is configured to urge the plunger toward the tubing segment to maintain contact with the tubing segment during the expansion of the pumping volume. The second biasing member is configured to urge the plunger toward the tubing segment to contract the pumping volume.Type: ApplicationFiled: January 27, 2022Publication date: July 28, 2022Inventors: Lun Zhang, Frank Cai, Derek Alan Carroll, Siddarth Shevgoor

Publication number: 20220086544Abstract: A bandwidth allocation method and a related device are disclosed. An exemplary method includes: when a total sum of a cumulative sum of fixed bandwidth configuration upper limits of traffic bearing entities and a cumulative sum of assured bandwidth configuration upper limits of the traffic bearing entities is greater than a maximum bandwidth value of a passive optical network (PON) port of a piece of central office equipment, determining, by the central office equipment based on a bandwidth configuration upper limit of each traffic bearing entity and a required bandwidth value of the traffic bearing entity, a bandwidth value actually allocated to the traffic bearing entity. In this way, a part of bandwidth is allocated to each traffic bearing entity. This avoids a case in which no bandwidth is allocated to some traffic bearing entities. Therefore, resource allocation is more appropriate.Type: ApplicationFiled: November 24, 2021Publication date: March 17, 2022Inventors: Lun ZHANG, Gang ZHENG
