Abstract: A catheter system for treating a vascular lesion within or adjacent to a vessel wall within a body of a patient includes a single light source that generates light energy, a first light guide and a second light guide, and a multiplexer. The first light guide and the second light guide are each configured to selectively receive light energy from the light source. The multiplexer receives the light energy from the light source in the form of a source beam and selectively directs the light energy from the light source in the form of individual guide beams to each of the first light guide and the second light guide.

Abstract: A pre-welding positioning system includes a frame body, a controller, a three-axis mechanism arranged on the frame body, and a vision acquisition system and a fixing component arranged on the three-axis mechanism. The controller is configured to control the three-axis mechanism to move to a designated position based on product information of a battery pack to be welded. The vision acquisition system is configured to acquire, at the designated position, an image of a positioning component of the battery pack, in response to the three-axis mechanism reaching the designated position, and determine a distance deviation value between the positioning component and a preset reference point based on the acquired detection image. The controller is further configured to control the three-axis mechanism to drive the fixing component to the positioning component based on the distance deviation value to fix the battery pack to the frame body by the fixing component.

Abstract: This application provides a stirring impeller type washing machine including a washing machine body, a washing assembly, and a water level assembly. The washing assembly includes a mode switch and a program controller connected to each other, the program controller has at least two switching positions, each corresponding to a working mode, different rotation orientations of the mode switch correspond to different working modes of the stirring impeller type washing machine. The water level assembly includes a water level sensor, an encoder connected to the water level sensor, and a water level switch and a water injection controller connected to the encoder, wherein a preset water level is adjustable through different rotation orientations of the water level switch. With the stirring impeller type washing machine, the operation and the control become more convenient and sensitive, and the washing degree is higher.
