The present invention relates to the technical field of photography and videography, in particular to a gear fine-tuning pan-tilt. The gear fine-tuning pan-tilt includes a rotating base, a roll worm support seat, a roll adjusting assembly, a pitch adjusting assembly, and a bearing seat arranged in sequence from bottom to top; the pitch adjusting assembly of the complete gear structure is located on the above, providing large-angle pitch ability, and the roll adjusting assembly located below adopts an arc-shaped rack structure, which reduces the interference to the pitching movement of the upper assembly and makes the height of the pan-tilt smaller. The arc opening of the arc-shaped rack faces upwards, so that the rotation axis is closer to the center axis of the lens, the camera displacement is small during the leveling process, and the unintended picture movement is small. The upper and lower combination of the two structures strengthens the swing ability of the top of the pan-tilt in the limited size, and is therefore more convenient to use: firstly aiming at the subject through the rotating base, and then leveling the left and right, and then determining the pitch angle. The camera always maintains the left and right level during pitching process. There is no need to level the left and right again after the pitch angle is changed, and roll deviation will not occur when the camera pitches and the lens is moved.

In embodiments, a connector for setting a layout of a brake hose includes a first coupling member coupled to one end of the brake hose; a second coupling member disposed to be spaced apart from the first coupling member, and coupled to the caliper housing or the frame of the master cylinder; and an adjusting unit connected at one end thereof to the first coupling member, connected at other end thereof to the second coupling member, and configured to adjust a shortest length between a bottom surface of the first coupling member and an outer circumferential surface of the second coupling member and to adjust a line passing through a center of the first coupling member with respect to the second coupling member to be positioned in one of up/down/left/right directions, in a test for setting the layout of the brake hose.

A mounting system is disclosed that includes a bracket configured to mount an object on a structure. The bracket includes a front panel, two side panels extending from the front panel, and a plurality of slots. Each slot is configured to accept a projection connected to the object and retain the projection within the slot. The bracket further includes a plurality of apertures. The mounting system further includes a retainer configured to extend into the bracket through the plurality of apertures and prevent, at least in part, the plurality of projections, retained by the bracket in the plurality of slots, from being withdrawn from the plurality of slots.

A robotic assistant includes a base; an elevation mechanism positioned on the base; a display rotatably mounted on the elevation mechanism; a camera positioned on the display; and a control system that receives command instructions. In response to the command instructions, the control system is to detect movement of a face of the user in a vertical direction based on the images captured by the camera. In response to detection of the movement of the face of the user in the vertical direction, the control system is to rotate the display and actuate the elevation mechanism to the move the display up and down to allow the camera to face the face of the user during the movement of the face of the user in the vertical direction.

An exemplary embodiment of the present invention provides a solar panel truss mounting system comprising a base and a truss assembly coupled to the base. The truss assembly comprises a first panel rail mount, second panel rail mount parallel to the first panel rail mount, base rail mount parallel to the first and second panel rail mounts, and a plurality of support members. A first portion of the plurality of support members extends between the first and second panel rail mounts. A second portion of the plurality of support members extends between the first panel rail mount and the base rail mount. A third portion of the plurality of support members extends between the second panel rail mount and the base rail mount. The system can further comprise a plurality of connectors for coupling a plurality of photovoltaic solar panels to the truss assembly.

An assembly includes an attachment arm having an axle extending from a first end of the attachment arm. The attachment arm of the detachable wheel assembly further includes a securing portion forming a second end of the attachment arm, the securing portion of the attachment arm including a pin positioned to extend above a first frame member of a gantry truss and to secure the first frame member between the pin and a portion of the attachment arm. The attachment arm also includes a frame support corresponding to a second frame member of the gantry truss such that the frame support supports the second frame member when the assembly is secured to the gantry truss, and the assembly includes a wheel rotatably attached to the axle of the attachment arm.

A cup holder insert for increasing the depth of an existing cup holder includes a generally cylindrical body with an open top, a bottom and a sidewall. The body also includes an upper lip extending outwardly from the sidewall and surrounding the top. An engagement system having a flexible lip, an engagement aperture and an alignment flange functions to secure the cup holder insert into an existing cup holder to increase the existing cup holder depth. A method for inserting the cup holder insert into an existing cup holder is also disclosed.

A method and an apparatus for isolating a vibration of a positioning device are provided. The apparatus includes a base plate for the positioning device, at least one active bearing element for bearing the base plate on/at a foundation and at least one evaluation and control device. The apparatus includes at least one means for determining a foundation movement-dependent quantity, wherein the active bearing element is controllable by the at least one control and evaluation device on the basis of the foundation movement-dependent quantity.

An explosion-proof housing 10 having at least one pressure relief body 15 arranged in a pressure compensation vent opening 14 of one of the housing parts 12, 13. In order to secure the pressure relief body 15 to the housing part 12, a thickened region 20 of the housing part 12 engages over an edge zone 24 of the pressure relief body 15 along its entire peripheral surface 23 on both of its flat sides 16, 17. A resulting engaging depth Si, which is measured parallel to the flat sides 16, 17, is preferably greater than a thickness D1, D2 of the part of the thickened region 20 engaging over the edge zone 24. The pressure relief element 15 consists of sintered wire mesh. This connection is pressure-resistant and stable over a wide temperature range.
