摘要:
A foldable dot sight device is provided that includes a body capable of being assembled into a firearm. A dot generator is disposed on the body, and is capable of generating a dot for aiming at a target. A reflective mirror is provided, which transmits an image of a target toward the user and reflects the dot generated by the dot generator. A housing is connected to the reflective mirror. A protective cover includes a sliding guide rotatably connected to the body and rotates the housing in a folding or unfolding direction according to a rotational position.

A sighting device includes a body, a light emitting unit, a bracket, a first adjusting unit and a second adjusting unit. The body couples to an arm having a barrel. The body is disposed relative to the arm in a first direction defined on an up and down axis. A third direction is defined as a direction of the barrel on a front and back axis. A second direction is defined as a left and right axis. The bracket couples to the light emitting unit. The first adjusting unit couples the bracket to the body and moves the bracket relative to the body. The second adjusting unit couples the bracket to the body and moves the bracket relative to the body.
摘要:
A media transmission method based on telepresence is disclosed, comprising: during connection establishment, a master telepresence terminal of a local media transmission system and a remote endpoint perform signaling exchange, to establish a media logical channel between the local media transmission system and the remote endpoint; and transmits the same type of media streams between the local media transmission system and the remote endpoint through a media logical channel or respectively through multiple media logical channels, and receives the same type of media streams through a media logical channel or respectively through multiple media logical channels. A media transmission system based on telepresence is further disclosed correspondingly. Through the disclosure, when a telepresence system of a certain conference site is called, only one number needs to be called, which is easy to operate; moreover, agent information exchange can be performed in the telepresence system, thereby achieving the effect of sound-based localization, solving the problem such as synchronization between streams, and improving user experience.

A fixing mechanism includes a mounting plate of a small arm accessory, a fixing member and an adjusting member. The mounting plate has a surface that faces the small arm when the mounting plate is fixed to the small arm. A first direction is defined as normal to the surface. The fixing member extends from the surface of the mounting plate in the first direction. The fixing member includes an aperture defined therein having an axis that defines a second direction different from the first direction. The adjusting member provides a fixing force to fix the small arm accessory to the small arm when inserted into the aperture of the fixing member.
