Abstract: The present invention discloses a tripod for rifle hunting comprising a connecting head with legs hinged thereto. The legs can rotate inwardly or outwardly relative to the connecting head around a hinge axis, and a locking component is installed on the connecting head to limit inward rotation of the legs. Compared to existing technology, the locking component on the connecting head restricts the legs after they are extended, preventing inward rotation relative to the connecting head. This ensures that the legs do not rotate inward due to kick recoil during shooting, thus maintaining the stability of the tripod and preventing collapse due to kick recoil force.

A locking assembly is provided in the first mounting chamber for sleeving on the first movable tube and locked with the first locking seat, a transmission assembly is mounted on the first locking seat to drive the locking assembly to be unlocked or locked, and a driving assembly is used to drive the transmission assembly. Compared to the prior art, the support reduces the size of the product, which is advantageous for carrying and storage.

Abstract: An actuator for moving an ultrasound transducer has a main body configured to be positioned adjacent to a target region of interest to be examined; and, a motor mounted on the main body. The motor is configured to have an ultrasound transducer connected thereto to simultaneously translate and rotate the ultrasound transducer to perform a compound scan of the target region of interest when the ultrasound transducer is connected to the motor. An ultrasound device has an ultrasound transducer movably mounted on the actuator. The actuator requires only single motor to effect both translation and rotation of the transducer thereby simplifying operation and providing a more compact device.

Abstract: A method for decoding a 360-degree image includes: receiving a bitstream obtained by encoding a 360-degree image; generating a prediction image by making reference to syntax information obtained from the received bitstream; combining the generated prediction image with a residual image obtained by dequantizing and inverse-transforming the bitstream, so as to obtain a decoded image; and reconstructing the decoded image into a 360-degree image according to a projection format. Here, generating the prediction image includes: checking, from the syntax information, prediction mode accuracy for a current block to be decoded; determining whether the checked prediction mode accuracy corresponds to most probable mode (MPM) information obtained from the syntax information; and when the checked prediction mode accuracy does not correspond to the MPM information, reconfiguring the MPM information according to the prediction mode accuracy for the current block.

The accommodating member includes an accommodating body and a connecting plate rotatably connected to the accommodating body. The mobile phone clamp assembly is disposed on the connecting plate and configured to be received in the accommodating body. The connecting plate rotates to allow the mobile phone clamp assembly to be received in the accommodating body. When the mobile phone clamp assembly is not in use, the connecting plate is rotated to allow the mobile phone clamp assembly to be received, so that space is saved and the accommodation and placement of the clamping and supporting apparatus are facilitated. The accommodating body is a handle, so that one can conveniently hold the accommodating body with one hand and open or close the connecting plate with the other hand.
