Abstract: A base, a laundry treatment device and a cleaning system are provided. The base includes a pedestal and a water inlet assembly. The pedestal includes a washing portion and a robot vacuum cleaner chamber. The washing portion is configured to wash a cleaning member of a robot vacuum cleaner. The water inlet assembly includes a primary water inlet path, and a first water inlet branch in fluid communication with the primary water inlet path and/or a second water inlet branch in fluid communication with the primary water inlet path. The primary water inlet path is configured to be fluidly connected to a tap water path. The first water inlet branch is in fluid communication with the washing portion. The second water inlet branch is configured to be fluidly connected to a liquid container of the robot vacuum cleaner.

Abstract: The disclosure relates to an oscillator control system with dynamic control for power saving.

Abstract: This application provides a lens element, an optical lens group, a mold, and spectacles. The lens element includes: a base region, where the base region includes a prescription region for correcting a refractive error of an eye; and a plurality of insular regions, where the insular regions include regions for inhibiting development of the refractive error of the eye, where at least some of the insular regions are adjacent to each other and have a shared edge; and for edges of all the insular regions on the lens element, a length of a shared edge portion is L1, a length of a non-shared edge portion is L2, and a ratio of L1 to L2 is 0.3 or more. The optical lens group includes a first lens element and a second lens element. When the first lens element and the second lens element are placed parallel to each other and coaxially, at least one relative position exists for the first lens element and the second lens element, to make the first lens element and the second lens element meet a specific relationship.
