Abstract: A label printer is provided. The label printer comprises a stationary housing (100) and a side cover (200) which are rotationally connected; a mechanism set is fixed in the stationary housing; at least two fixed shafts are set between a first side plate (800) and a second side plate (801) of the printer module frame; a pinch plate (5) used to support the second side plate is rotationally installed at the side of the mechanism base; a printer set (10,2,1) between the first side plate and the second side plate. The label printer in the invention is convenient to change or assemble the consumable.

Abstract: An autonomous mobile device system includes a plurality of magnetic components and an autonomous mobile device. The magnetic components are adapted to be arranged on a surface in a space-apart manner and produce a magnetic field serving as a virtual boundary on the surface. The autonomous mobile device is configured to move on the surface, and includes a housing, a magnetic sensor for detecting the magnetic field, and a motion control module for controlling movement of the autonomous mobile device. The motion control module is operable in a first movement mode, in which the autonomous mobile device is restrained from crossing the virtual boundary when the magnetic sensor detects the magnetic field.

Abstract: Embodiments of the present disclosure provide an Ethernet ring protection switching method, network device and system. In the embodiments of the present disclosure, a node obtains bandwidth information of a first link on an Ethernet ring on which the node is located, and determines that bandwidth of the first link changes, where there is at least one Ethernet ring protection instance on the Ethernet ring, and then the node determines ports of the node, where the at least one Ethernet ring protection instance passes through the ports, so that the node can query pre-configured correspondence between bandwidth information and switching information of each link on the Ethernet ring, and execute, through the ports of the node, a switching operation corresponding to the bandwidth information of the first link.

Abstract: A quaternary oxide includes a dopant metal, a dopant nonmetal, titanium, and oxygen. The atomic ratio of titanium, oxygen and dopant nonmetal may be 1:0.5-1.99:0.01-1.5. Quaternary oxides may be used in catalytic compositions, in coatings for disinfecting surfaces and in coatings for self-cleaning surfaces. A method of making a quaternary oxide includes combining ingredients including a titanium source, a dopant nonmetal source, a dopant metal salt, and a polar organic solvent to form a reaction mixture; and heating the reaction mixture.

Abstract: A first pilot signal is transmitted at a first frequency for a first coverage area (e.g., an outdoor area). A second pilot signal is transmitted at a second frequency for a second coverage area (e.g., an indoor area). The first pilot signal at the second frequency is transmitted into a portion of the second coverage area, the second coverage area at least overlapping with the first coverage area. Further, the first pilot signal is transmitted at the second frequency in the second coverage area. In an example, the first pilot signal at the first frequency is transmitted from an outdoor base station, the second pilot signal at the second frequency is transmitted by an indoor base station, the first pilot signal at the second frequency is transmitted into the second coverage area (e.g., an interior of a building from a building exit point) by an antenna (e.g., not necessarily at a base station) and the second pilot signal at the first frequency is transmitted by the indoor base station.

Abstract: A system and method for analyzing data from a gel permeation chromatography (GPC) or size exclusion chromatography (SEC) system fro determining a polymeric sample's radius of gyration. Data from two or more detectors is used with a least-squares minimization fit. A novel method includes the simultaneous determination of a sample's radius of gyration using data from a light scattering detector that collects data from at least two incident angles. Detectors within the inventive method include a multi-angle light scattering (LS) detector, viscometer (V) and a refractive index (RI) detector.

Abstract: The photosensitive compound of the present invention contains the following unit: ##STR1## and is particularly expressed by the following formula: ##STR2## Different photosensitive resin compositions can be prepared from this novel photosensitive resin compound, and the resulting photosensitive resin compositions do not raise the problem of environmental pollution, exhibit high resolution, possess a high level of sensitivity, and exhibit excellent adhesion with substrates, coating characteristics and storage stability.
