Abstract: The present invention discloses a high-precision and miniaturized on-orbit calibration device for a six-dimensional force sensor of a space station manipulator and a calibration method thereof, which include an inverted ? shape fixing bracket, three force applying devices, and a cubic stress block. Each force applying device includes a force applying head, a single axis force sensor, a force source part and a fastening part. The force source part includes an upper support plate, a second electrode plate, piezoelectric ceramic plates, a first electrode plate and a lower support plate, which are coaxially arranged sequentially from top to bottom. The single axis force sensor is mounted on the top of the upper support plate, and the hemispherical force applying head is mounted on the top of the single axis force sensor. The cubic stress block is mounted on the top of the six-dimensional force sensor.

Abstract: The present invention relates to a method for reducing dynamic power consumption and an electronic device. The method includes: receiving a bus signal; when information about access to the slave device exists in the bus signal, inputting a clock signal into the slave device and detecting a status signal sent by the slave device; and stopping inputting the clock signal into the slave device when the status signal of the slave device indicates that the slave device is in an idle state. A working clock of a device module, such as a slave device, in a chip is controlled by using a status signal of the slave device and a bus signal, which prevents unnecessary circuit turnover from occurring to the device module in the chip in a non-working state, thereby achieving a purpose of reducing dynamic power consumption of the device module in the chip.
