Abstract: A signal processing system and method for a radiation detector based on a metal oxide semiconductor (MOS) transistor are disclosed. The signal processing system includes a power supply generation module, an analog signal processing module, and a digital signal acquiring-processing module. The power supply generation module provides a novel power supply method, and converts a positive high voltage power supply into a negative high voltage power supply to supply power to a last dynode of a photomultiplier tube (PMT). The analog signal processing module converts a negative current pulse signal into a voltage difference signal. The digital signal acquiring-processing module acquires a signal of the analog signal processing module, and converts the signal into a digital signal for identification.

Abstract: An intelligent vacuum device is provided. A main body of the vacuum device has a dust bin and a main vacuum port formed on a bottom side thereof and communicated with the dust bin. An extendable suction arm is switchable relative to the main body between a first position and at least one second position. The extendable suction arm has at least one actuator and at least one arm vacuum port thereon, and the arm vacuum port is communicated with the dust bin. At least one detection sensor is disposed on the main body to detect a surrounding environment of the vacuum device and generate corresponding sensing signals. A controller is used to control movement of the vacuum device based on the sensing signals, and control the at least one actuator to switch the extendable suction arm between the first position and the at least one second position.

Abstract: An autonomous mobile steam cleaning device includes a mobile robot being formed with a hot steam/vapor generator and a first water tank with hot water during autonomous steam cleaning; a base station providing either hot water or water and power to pre-heat water to the first water tank before autonomous steam cleaning commences; and a steam dispersing apparatus provided with at least one steam port in communication with the hot steam./vapor generator.

Abstract: An end effector for a robotic arm. The end effector includes an angle compensator for attaching a suction cup, a vacuum control valve, a vacuum generator, a level compensator, and an extension tube which are sequentially connected along a central axis and in fluid communication, and a vacuum sensor connected to the vacuum control valve for measuring vacuum, a proximity sensor attached to the extension tube 121 for determining position of the level compensator. The vacuum is generated when compressed air passes the extension tube, the level compensator and the vacuum generator along the central axis. The level compensator provides compensation along the central axis.
