Abstract: A wheel assembly has a wheel with a hub. A rotation surface disposed in the hub has a bore. A sleeve insertable in the bore of the rotation surface has an outer surface with a circumferential groove and first and second opposite axial ends. The first axial end has a shoulder extending radially outward. A resilient ring disposed in the circumferential groove is compressible to a compression diameter sufficient to enable the sleeve to be inserted in the bore of the rotation surface. The resilient ring is expandable to an expansion diameter greater than the inner surface diameter of the bore of the rotation surface when unconstrained. The circumferential groove is spaced from the shoulder at a distance sufficient to enable the resilient ring to expand to the expansion diameter when the sleeve is inserted in the bore of the rotation surface and the shoulder is adjacent the rotation surface.

Abstract: A dual-mode rapidly-passing type moving target radiation inspection system comprises a radiation source, a collimator, sensor units, a control module, a radiation detector and a radiation imaging device, wherein the sensor units are used for identifying the type of a moving target and monitoring the position of the moving target in an inspection channel; the control module is used for controlling the radiation source to emit rays in a preset working mode on the basis of the type and the position of the moving target; the preset working mode corresponds to the type of the moving target, and the rays emitted by the radiation source in different working modes differ in dosage rate. Also disclosed is a dual-mode rapidly-passing type moving target radiation inspection method. The inspection system and method described above are capable of radiation inspection of the entire moving targets such as vehicles.

Abstract: A system and method for radiation inspection on a moving object. The system comprises a radiation source and a radiation detector. Rays emitted by the radiation source are limited in a scanning area. The scanning area is provided by a first boundary surface and a second boundary surface. The system also comprises: multiple detection units arranged along a detection channel in turn and used for triggering and sending a signal when detecting that the moving object arrives or leaves; and a control module used for receiving signals sent by the multiple detection units and controlling the radiation source according to the received signal. The first to third detection units among the multiple detection units are located at one side of the scanning area and near the first boundary surface. The fourth to sixth detection units among the multiple detection units are located at the other side of the scanning area and near the second boundary surface.

Abstract: A USB printer sharing switch device with automatic switching capabilities is provided for multiple computers to share a USB printer. The sharing switch device transfers USB data between the computers and the printer without changing the data format. The automatic switching function is performed by hardware and firmware of the sharing switch device in cooperation with driver software on the computers. In one implementation, the sharing switch device includes multiple USB device controllers corresponding to the multiple computers, and employs multiple switches and a USB hub so that each computer is connected to its corresponding controller and the computer that is currently connected to the printer can communicate with its controller while printing. The current computer transmits a spooling finished command to its controller when spooling is finished. After receiving the spooling finished command, the sharing switch device automatically switches the printer to another computer.
