The present disclosure provides a device for in-water automatic spreading configured to spread a medicament in a water body. The device includes a storage module configured to store a medicament to be spread and a driving module configured to drive the medicament to be spread to be separated from the storage module. The driving module is connected with the storage module. The device may also include a medicament outlet configured as an outlet for the medicament to be spread to enter a liquid after being separated from the storage module, a walking module configured to drive the device for in-water automatic spreading to move in the water body according to a walking route, and a control module configured to control the driving module and the walking module. The control module is connected with the driving module and the walking module.

Provided are a chip security module and a security encryption method. The encryption operation instruction is monitored, and whether the execution process of the encryption operation instruction matches a security sequence is determined. If the execution process of the encryption operation instruction matches the security sequence, the chip security module controls that an execution result is outputted based on the encryption operation instruction. If the execution process of the encryption operation instruction does not match the security sequence, a corresponding action is taken according to application requirements. The security sequence characterizes a preset execution process of the corresponding encryption operation instruction. The present invention improves chip security. Different security sequences are configured for different application needs. Design cost of the chip is reduced.

A foldable walking pad includes a first walking pad, a second walking pad and a folding assembly that connects the first fixing plate and the second fixing plate.

The present disclosure provides a laser power correction method, device, and laser for suppressing relaxation oscillation. The method includes: setting the laser to a first duty cycle and a first frequency, adjusting current so that the average power is a preset power, and recording the present current value; adjusting the frequency so that the average power is the preset power, recording all frequency values to obtain a frequency interval; changing the duty cycle to obtain frequency intervals at various duty cycles; setting the laser to a second duty cycle and the representative frequency, adjusting the current so that the average power is the minimum/maximum average power, recording the minimum and maximum currents, and determining a current-average power relationship; changing the duty cycle to obtain the current-average power relationship at various duty cycles and in different frequency intervals. The present disclosure is applicable to a pulsed laser control method that adds a small step signal to suppress relaxation oscillation. The current-average power relationship is determined by actually measuring the power output value, thereby achieving accurate correction of the laser.

Swimming pool robot, including: a body; two moving mechanisms (1071) provided on two sides of the body; and a lateral propulsion assembly (115). The lateral propulsion assembly includes: a lateral flow channel (115a) provided with a fluid inlet (115d) and a fluid spraying opening (115e); a lateral impeller (115c) provided inside the lateral flow channel; and a lateral motor configured to drive the lateral impeller to rotate. The fluid spraying opening is provided on one moving mechanism, so that the lateral flow channel communicates with the outside.
