Abstract: Embodiments of the present invention disclose a snap-in member, an assembled decking combination and a member of assembling decking, relating to the field of decking assembling. Among them, the snap-in member comprises a first snap-in seat, a second snap-in seat and a connecting base; wherein the other side of said first snap-in seat is configured with a driving groove for driving the rotation of said first snap-in seat, said second snap-in seat and said connecting base, such that the first snap-in seat and the second snap-in seat are snapped into and limit a joist and a decking body, respectively. The present invention mounts two adjacent decking bodies on the same joist only by adjusting the angle of a snap-in member, which is simple and easy to operate and effectively improves the efficiency of installation and disassembly of decking bodies.

Abstract: The provided is a visualized biological trawl net system based on a submersible. The visualized biological trawl net system based on a submersible includes a fixation frame, and further includes a collection net, a filtering mechanism, a fish school observation camera and a central control system. The collection net is arranged at a rear of the fixation frame and used for collecting marine creatures; the filtering mechanism is arranged inside the fixation frame, and the filtering mechanism is used for screening marine creatures entering the collection net; the fish school observation camera is arranged at a top of the fixation frame, and the fish school observation camera is used for observing marine creatures; and the central control system is electrically connected with the fish school observation camera and used for controlling the fish school observation camera to monitor marine creatures.

Abstract: The present description relates to devices, such as keyboards. One example can include a top portion and an opposing bottom portion and key switches that are mechanically retained in holes formed in the top cover. The example can also include electrical traces formed on the top cover that extend from the holes to a processing unit that is configured to receive electrical signals along the electrical traces when the key switches are closed.

Abstract: A deep-sea crawling robot and a crawling method thereof are provided. The deep-sea crawling robot includes a crawling robot body and a countertop, wherein a top of the crawling robot body is fixedly connected to the countertop, left and right sides of a bottom of the crawling robot body are respectively provided with crawler belts, and left and right sides of the countertop are respectively provided with weight-increasing auxiliary crawling mechanisms; and an outer plate is fixedly connected to a front side or back side of the countertop, a multifunctional propelling mechanism is arranged on the outer plate, and a rapid dewatering mechanism is arranged in a chamber of the countertop. The deep-sea crawling robot can not only accelerate the propulsion and crawling speed when it is on the seabed but also further enhance its stability during the crawling process on the seabed.

Abstract: A pointing device is provided. In one implementation, the pointing device includes a body, a control member received in a recess of the body and rotatable with respect to the body, a first rotation tracking sensor arranged in the recess and configured to track a rotation of the control member about a first axis and a second axis perpendicular to the first axis in a Cartesian coordinate system that is defined with respect to the recess, and a second rotation tracking sensor arranged in the recess and configured to track a rotation of the control member about a third axis perpendicular to the first and second axes in the Cartesian coordinate system. An associated method of manufacturing the pointing device is also provided.

Abstract: An error-correction apparatus and method and a three-dimensional (3D) pointing device using the error-correction apparatus are provided. The error-correction apparatus includes a data-collection module which collects current data and calculates an actual variation in the current data; an estimation module which calculates an estimated data variation for the current data based on a number of data variations for respective corresponding previous data; a threshold-calculation module which calculates a variable threshold based on the data variations for the respective previous data; and a determination module which compares the difference between the actual data variation and the estimated data variation with the variable threshold and determines whether the current data is erroneous based on the result of the comparison.
