A driving system for a matrix type backlight module having a plurality of light spots is provided. The driving system includes a timing controller providing a timing signal to control a starting up sequence and a turning on time for each of the plurality of light spots, a row driver electrically connected to the timing controller and providing a turning on time of the matrix type backlight module in a row direction according to the timing signal, and a column driver electrically connected to the timing controller and providing a turning on time of the matrix type backlight module in a column direction according to the timing signal.

The invention discloses an underwater sub system-master system matrix type synchronous release apparatus, which comprises a control cabin, a motor, a threaded connecting rod, support rods, a multi-connecting rod combination mechanism and a bracket, wherein the rotating shaft of the motor and one end of the threaded connecting rod form transmission connection, the other end of the threaded connecting rod is provided with a bearing, the bearing is fixed at one end of the support rod, a traction tray is arranged on the threaded connecting rod, the multi-connecting rod combination mechanism comprises a plurality of connecting rod groups, each connecting rod group corresponds to the release of a sub system, the motor drives the threaded connecting rod to rotate, and the threaded connecting roddrives the traction tray to move linearly, such that the connecting rod groups are driven to be unfolded so as to release the sub systems. According to the present invention, the parallelogram connecting rod is formed by using the umbrella skeleton model principle, such that the sub system cannot shake left and right during the release; and the four groups of the parallelograms are fixed on the same traction tray, and the movement up and down of the traction tray drives the four groups of the parallel rod structures to perform the same stretching and contraction movements so as to ensure the identity of the release.

The invention provides an assistant measurement tool and method for detecting intervals between installation holes of aerospace products. The assistant measurement tool comprises a detection substrate and locating blocks, wherein the detection substrate is provided with scales, and the locating blocks are installed on the detection substrate and used for locating the lengths of hole intervals. The detection substrate comprises two matrix type scale boards perpendicular to each other in direction. Each locating block comprises a locating bottom block and a locating rod. The locating rods are connected with the matrix type scale boards through the locating bottom blocks. The centers of the locating rods coincide with the centers of the locating bottom blocks. The assistant measurement tool and method for detecting intervals between installation holes of aerospace products can conveniently and rapidly detect whether the intervals of installation holes of aerospace products meet the requirement or not, can efficiently and rapidly detect the intervals of installation holes of aerospace products of different sizes, improves the detection efficiency, and is easy to operate and convenient to use.
