A radiation image pick-up apparatus includes a conversion element, accumulation element, read element, detection element, driving circuit, and controller. The conversion element converts radiation into an electrical signal. The accumulation unit accumulates the electrical signal converted by the conversion element. The read unit reads out the electrical signal accumulated in the accumulation unit. The detection element detects the start and end of irradiation of the radiation. The driving circuit accumulates the electrical signal in the accumulation element responsive to the detection of start of irradiation of the radiation, and drives the read element responsive to the detection of the end of irradiation of the radiation, based on the detection result of the detection element. The controller controls the driving circuit. A radiation image pick-up system is also disclosed.

A fuel pump and filter assembly includes a housing supporting a filter in a filter chamber, which is at least partially defined by first and second end walls, an outer wall extending therebetween, and an inner side wall disposed radially inwardly of the outer side wall. A fuel pump assembly is carried by the housing radially inwardly of the inner side wall and includes a sleeve that extends from the first end wall of the housing to the second end wall of the housing.

The invention discloses a structure of a case connection scheme without cables. The structure comprises a case component (13), a bottom board (10), a plurality of rear plugboard (3), an aviation plugboard component (2), a rear panel component (1) and a fixed device (4), wherein the aviation plugboard component (2) comprises an aviation plug printed board (9), a plurality of aviation plugs (5) anda fixed block (6); the aviation plugboard component (2) is connected with the rear plugboard (3) through a connector A; the rear plugboard (3) is connected with the bottom board (10) through a connector B; the fixed device (4) ensures that the rear plugboard (3) is smoothly plugged into a guide rail (12); all the rear plugboards (3) are plugged into the case component (13) through the guide rail (12). The structure cancels wire harnesses inside a case, improves the reliability of the case, reduces assembly hours, and further improves the heat dissipation performance of the case.

A sensor is used for judging the position state of a first tested object and a second tested object adjacent to each other and comprises an air valve which is arranged on the first tested object, wherein the air valve comprises a shell and a cavity formed in the shell; a first sound production device which is fixedly arranged at one end of the shell and is communicated with the cavity; a second sound production device which is fixedly arranged at the other end of the shell and is communicated with the cavity; and a piston which is connected with the second tested object and the air valve, wherein the piston comprises a plug body and a push rod extending out from one side of the plug body, the plug body is slidably connected to the inner side wall of the cavity to form an air chamber, and the tail end of the push rod is connected with the second tested object. A monitoring system comprises a monitoring module and the sensor installed on the second tested object, and is used for monitoring the position state of the first tested object and the second tested object adjacent to each other. The sensor does not generate noise during working, and does not need a power supply. Wire arranging and replacement of a battery are avoided, and the installation and maintenance are convenient.

The invention discloses a wireless blasting vibration monitoring system capable of freely networking and a control method. A vibration sensor interface is respectively connected with a multi-channel analog switch which is connected with an attenuator and an amplifier which are in parallel, the attenuator and the amplifier are respectively connected with a low pass filter, the output end of the low pass filter is connected with the input end of an A / D converter, the output end of the A / D converter is connected with a CPLD (Complex Programable Logic Device) control logic which is respectively connected with a crystal oscillator, a DPRAM (Double Port Random Memory) and an EEPROM (Electrically Erasable Programmable Read - Only Memory), an MCU 224 (Microprogrammed Control Unit) is connected with the CPLD control logic, and a wireless transmission module is connected with the MCU through an RS232 interface.
