A biaxial pivoting mechanism configured for connecting an object to a holder includes a mount component, a rotatable connector, a main body and a mount base. The mount component is configured to be fixed to the object. The rotatable connector is rotatably disposed on the mount component about a first axis. The main body is fixed to the rotatable connector. The mount base is configured to be fixed to the holder, and the main body is rotatably disposed on the mount base about a second axis not parallel to the first axis. The main body has a first surface, a second surface, and an accommodating space. The first surface is located closer to the rotatable connector than the second surface. The accommodating space extends to the second surface from the first surface. At least part of the mount base is located in the accommodating space.

Method and system allowing more accurate detection and identification of unwanted arcing include novel processing of signal voltage representing recovered power-line current. In one implementation, arc-faults are detected based on numerical analysis where individual cycles of line voltage and current are observed and data collected during each cycle is processed to estimate likelihood of presence of arc-event within each individual cycle based on pre-defined number of arc-events occurring within pre-defined number of contiguous cycles. In another implementation, fast transient current spikes detection can be done by: computing difference values between consecutive line-current samples collected over a cycle, average of differences, and peak-to-peak value of line-current; comparing each difference value to average of difference; comparing each difference value to peak-to-peak value; and, based on calculation of composite of two comparisons, using thresholds to determine if arcing is present within processed cycle.

This application is directed to a passively-cooled electronic device including a housing, a plurality of electronic assemblies and a plurality of thermally conductive parts. The electronic assemblies are enclosed in the housing, and include a first electronic assembly and a second electronic assembly. The first and second electronic assemblies are disposed proximately to each other within the housing, and the second electronic assembly is substantially sensitive to heat, including heat generated by operation of the first electronic assembly. The thermally conductive parts are coupled between the first electronic assembly and the housing, and configured to create a first plurality of heat conduction paths to conduct the heat generated by the first electronic assembly away from the second electronic assembly without using a fan. At least a subset of the thermally conductive parts mechanically supports one or both of the first and second electronic assemblies.

A system includes a robotic camera and a robotic display. The robotic camera has a robotic camera mount that moves an image capture device such as a camera and the robotic display has a robotic display mount that moves an image display device, such as a video display. The robotic mounts are used to synchronously move the camera and display so that they are in positions where captured images are displayed in the same orientation, e.g. images captured in a portrait orientation are displayed by the display in the same orientation and images captured in a landscape orientation are displayed by the display in the same orientation.

A robotic mount is configured to move an entertainment element such as a video display, a video projector, a video projector screen or a camera. The robotic mount is moveable in multiple degrees of freedom, whereby the associated entertainment element is moveable in three-dimensional space. In one embodiment, a system of entertainment elements are made to move and operate in synchronicity with each other, such as to move a single camera via multiple robotic mounts to one or more positions or along one or more paths.

A gimbal control method, a gimbal and a computer-readable storage medium including the gimbal control method are provided. The gimbal control method may include determining a target attitude angle of a gimbal, determining an attitude deviation value of the gimbal based on the target attitude angle and a current attitude angle of a clamping portion of the gimbal, generating a corresponding centering control instruction based upon the attitude deviation value, and executing the centering control instruction to control the gimbal to return to a center position.

A gimbal and a gimbal control method are disclosed. The gimbal control method may include: acquiring attitude information of a gimbal; determining whether the gimbal is in a falling state based upon the attitude information; and when the gimbal is in the falling state, triggering a protection mode and controlling the gimbal to rotate to a set attitude. The set attitude may be an attitude at which the gimbal is not easy to be broken from falling, thereby reducing the probability of the gimbal being broken from falling.

A handheld gimbal. The handheld gimbal may include a handle; a first shaft assembly including a first rotating shaft, a first shaft motor for driving the first rotating shaft, and a first connecting arm connected with the first rotating shaft; a second shaft assembly including a second rotating shaft, a second shaft motor for driving the second rotating shaft, and a second connecting arm connected to the second rotating shaft; a third shaft assembly including a third rotating shaft and a third shaft motor for driving the third rotating shaft; and a bearing portion connected with the third shaft assembly and configured to carry a shooting equipment. When the handheld gimbal is changed from the usage state to a storage state, the second shaft motor may be configured to provide driving force to rotate the second connecting arm to fold the handheld gimbal.

A multi-dimensional microphone stand includes a first rotational module, a first rotational arm, a second rotational module, a second rotational arm, and a third rotational module. The first rotational arm is connected to the first rotational module, and the second rotational module is connected to the first rotational arm, and the first rotational module is rotatable relative to the second rotational module. The second rotational arm is connected to the second rotational module, the third rotational module is connected to the second rotational arm, and the second rotational module is rotatable relative to the third rotational module. In addition, in a folded state, the first rotational arm and the second rotational arm are arranged side by side and connected to the second rotational module in parallel.

The handheld gimbal includes a plurality of use modes corresponding to a plurality of attitudes of the first bracket. When the handle part is substantially in a vertical state, the handle part is tilted counterclockwise or clockwise to rotate the handle part around a roll axis, and the first motor follows the handle part to rotate to drive the first bracket to rotate around the roll axis. When the handle part is substantially in a horizontal state, the handle part is tilted counterclockwise or clockwise to rotate the handle part around a yaw axis, and the first motor follows the handle part to rotate to drive the first bracket to rotate around the yaw axis.
