The adjustor is linked with the first and second adjustable members and configured to be driven to rotate at a rotatable direction along a centerline of the adjustment channel to selectively adjust a width of the adjustment channel so as to selectively adjust the distance between the first and second seat bodies.

Abstract: An electrical responsive graphene-PVDF material and the manufacturing method thereof is disclosed in the present invention. The method includes three steps. Firstly, prepare a mother solution of PVDF. Then, add graphene powders into the mother solution of PVDF to prepare a graphene-PVDF slurry. At last, remove the solvent from the graphene-PVDF slurry to directly form an electrical responsive graphene-PVDF material. Due to the ability of transforming the non-electrical energy into the electrical energy, the electrical responsive graphene-PVDF material can be formed for many different applications in the form of individual film or of film with a substrate via various film formation methods.

Abstract: A robotic cleaner may include one or more driven wheels, at least one environmental sensor, and a mop module. The mop module may include a tank having a tank inlet and a tank outlet, a pad coupled at a bottom side of the tank, the pad configured to contact a surface to be cleaned and to receive liquid from the tank outlet, and a latch configured to transition between a latched position, a release position, and a refill position. When in the latched position and in the release position, at least a portion of the latch may extend over the tank inlet and, when in the refill position, the latch may be displaced from the tank inlet, exposing the tank inlet.

Abstract: A connection manner identification method includes power sourcing equipment separately sending load adjustment indications to powered devices by using data ports, where each load adjustment indication in the load adjustment indications indicates a corresponding powered device to adjust a load. The powered devices are separately connected to power supply ports of the power sourcing equipment by using power supply cables, and the powered devices are separately connected to the data ports of the power sourcing equipment by using data cables. The power sourcing equipment obtains output power changes of the power supply ports caused by load adjustment of the powered devices, and the power sourcing equipment determines, based on the output power changes, a first data port and a power supply port that are connected to a same powered device in the powered devices.
