A connection apparatus of a detachable gimbal and an unmanned aerial vehicle are disclosed. The connection apparatus of a detachable gimbal includes: an alignment component, where the alignment component is configured to align a circuit connection terminal of an unmanned aerial vehicle with a circuit connection terminal of a gimbal; a pre-installed component disposed on the alignment component, where the pre-installed component moves relative to the alignment component to fixedly connect the gimbal to a fuselage of the unmanned aerial vehicle; and a locking component disposed on the pre-installed component, where the locking component locks the pre-installed component when the pre-installed component moves relative to the alignment component to a preset location.

The present invention discloses a display stand has a mounting seat connected on a support structure, internally provided with an accommodating cavity and having a slot communicated with the accommodating cavity at the top in an open way, a supporting arm having an insertion end capable of being inserted into the accommodating cavity of the mounting seat from the slot of the mounting seat, and a locking mechanism disposed on the mounting seat or supporting arm, for locking or unlocking the insertion end of the supporting arm in the accommodating cavity. When the insertion end of the supporting arm is locked, the supporting arm is limited within the accommodating cavity of the mounting seat, and when the insertion end of the supporting arm is unlocked, the insertion end of the supporting arm may be taken out from the slot of the mounting seat.

A display stand holder with slide rail structure includes a stand body, a pivot member, a display assembly module, and one or more constant-force springs. The stand body has a top end. The pivot member has a first end and a second end. The first end is provided with a pivot portion. The pivot portion is pivotally connected to the top end of the stand body, and the second end is away from the top end with respect to the first end. The display assembly module is disposed at the second end of the pivot member. The display module includes a slide rail assembly. The slide rail assembly includes a guide member and a slide member, and the slide member is slidably assembled on the guide member. The constant-force spring is connected between the guide member and the slide member.

A structural mount is used for attaching devices to a gutter. The mount includes a gutter engaging portion and a device engaging portion. The gutter engaging portion including two gutter mounts. The gutter mounts include a spiral hook and a stabilizer. The spiral hook extends above a gutter lip and into a gutter channel such that a proximal point of the spiral hook is positioned against an inner surface of a front wall of the gutter, and the stabilizer contacts an outer surface of the front wall of the gutter when the attachment device is engaged with the gutter. The device engaging portion includes a mounting surface and a mounting plate. The mounting plate is capable of receiving a securing clip attached to a device such that the device may engage with the mounting surface via the mounting plate and the securing clip.

A method for detecting a payload on a carrier configured to support the payload includes obtaining a obtaining at least one motion characteristic of the carrier. The at least one motion characteristic is indicative of a coupling state between the carrier and the payload. The method further includes assessing the coupling state between the carrier and the payload based on the at least one motion characteristic. Assessing the coupling state between the carrier and the payload includes at least one of assessing whether the payload is coupled to the carrier or assessing whether the payload is correctly mounted at the carrier.

A solar tracker assembly is provided which includes a support column, a torque tube or torsion beam connected to the support column, a mounting mechanism attached to the torque tube or torsion beam, a drive system connected to the torque tube or torsion beam, and a spring counter-balance assembly connected to the torque tube or torsion beam. An exemplary spring counter-balance assembly comprises a bearing housing and a bushing disposed within the bearing housing and configured to be slideably mounted onto the torque tube or torsion beam, and one or more compressible cords made of a flexible material. The compressible cords are located between the bushing and the bearing housing and provide damping during rotational movement of the solar tracker assembly. An exemplary spring counter-balance assembly is provided including at least one top bracket and at least one bottom bracket, at least one spring, a damper, and a bracket. An exemplary spring counter-balance assembly comprises a bearing housing and a bushing disposed within the bearing housing and configured to be slideably mounted onto the torque tube or torsion beam. The spring counter-balance assembly may include at least one coil spring and a rotational stop. The bushing may be made of an elastomeric material and define one or more air spaces.

A system can include a stand that includes a base and an upright; at least one arm mountable to the upright; and serial transmission port circuitry operatively coupled to a plurality of serial transmission ports disposed along the upright.

An angle adjustment and rotation system comprising a first element attachable to a luminaire stand, and a second element configured to be attachable to a luminaire head, the first element and second element comprising substantially complementary shapes, and an attaching element configured to have a first state in which it tightly attaches the first element to the second element and a second state in which it movably attaches the first element to the second element. In the second state, the attaching element enables a rotation over substantially 180 degrees of the second element with respect to the first element. A method of controlling the orientation of a luminaire head connected to a luminaire stand is also proposed, preferably using the proposed system.

A screen support frame includes a base and a supporting member that includes a supporting member mounting portion, which has one end mounted to the base and an opposite end formed with a protrusion, and a supporting member rotating portion including a receiving hole in which the protrusion of the supporting member mounting portion is received. The supporting member rotating portion includes rails, between which a longitudinally movable member is arranged. A frontward projection arm extends from one side of the longitudinally movable member. A screen fixing portion is mounted to the frontward projection arm of the longitudinally movable member of the supporting member rotating portion and includes symmetrically arranged elastic members and symmetrically arranged friction members. The screen fixing portion further includes a rotating disc. The present invention provides effects of adjusting of angle of rotation, vertical position, elevational angle, and sideway rotating angle.
