A gimbal arrangement includes a static structure, a gimbal supported for rotation relative to the static structure, an actuator operably connected to the gimbal and configured to rotate the gimbal relative to the static structure, and a magnetic soft stop. The magnetic soft stop is connected between the static structure and the gimbal to limit rotation of the gimbal relative to the static structure to within a predetermined range. Sensor systems and imaging methods are also described.

An object or body-mounted camera apparatus for recording surgery is provided that is adapted for tracking a relevant visual field of an on-going operation. To help maintain visibility and/or focus of the visual field, specific machine learning approaches are proposed in combination with control commands to shift a physical positioning or a perspective of the camera apparatus. Additional variations are directed to tracking obstructions based on the visual field of the camera, which can be utilized for determining a primary recording for use when there are multiple cameras being used in concert.

A reel assembly for an agricultural header includes a reel arm configured to couple to a frame of the agricultural header and configured to support a reel of the reel assembly. The reel assembly further includes a device mounting assembly movably coupled to the reel arm and configured to support a device that is configured to monitor a terrain feature. The device mounting assembly is configured to move between an extended position and a retracted position relative to the frame to move the device between a first position corresponding to the extended position of the device mounting assembly and a second position corresponding to the retracted position of the device mounting assembly. The device mounting assembly is configured to enable the device to monitor the terrain feature at the first position and the second position.

A reel assembly for an agricultural header including a reel arm configured to rotatably couple to a frame of the agricultural header and configured to support a reel of the reel assembly. The reel assembly further includes a device mounting assembly coupled to the reel arm and configured to support a device that is configured to monitor a terrain feature. The device mounting assembly is configured to maintain an orientation between the device and a ground on which the agricultural header is positioned as the reel arm rotates relative to the frame of the agricultural header.

A method for aligning the field of view of a user with the field of view of a camera mounted on the user's head may include providing at least one head-mounted camera module that includes at least one sensor that in turn includes an image sensor, where the said image sensor outputs video of an area; receiving a first input from a user to expect a second input relating to the field of view; receiving the second input relating to the field of view; and aligning the field of view of the user with the field of view of the camera.

A laser tool comprises at least one laser emitter, a housing, and a support. The laser emitter is for emitting at least one laser beam from the tool. The housing supports and at least partially contains the laser emitter, and the housing and the laser emitter may comprise a laser unit. The support is external to the housing, for supporting the housing, and the support is adjustable for orienting the housing and thereby orienting and positioning the laser beam. The support preferably is a gimbal support, having at least two, preferably at least three, for example exactly three, non-parallel rotational axes, for adjusting the support to orient the housing and thereby orient the laser beam. A laser tool system may comprise two or more laser units and the support.

A system and method for guiding placement of a vehicle service external fixture relative to a vehicle undergoing service or inspection. A vehicle service system support structure having at least one camera module is positioned at an initial location within a vehicle service area, and a location of the initial location within a vehicle reference frame is established from images of optical targets secured to the vehicle. The vehicle service system support structure is subsequently repositioned relative to the vehicle to a new position located outside of an external fixture placement region, while maintaining at least one of the observed optical targets within a field of view of the camera module. The new position of the vehicle service system support structure within said vehicle reference frame is determined from target images, and a placement location within the placement region for the external fixture is identified relative to the vehicle.

A load-stabilizing apparatus includes a load-connecting member configured to carry a load, a connecting assembly connected to the load-connecting member, and a stabilizing motor drivingly connected to the connecting assembly and configured to drive the connecting assembly to move, such that the connecting assembly drives the load-connecting member to move translationally.

A support device includes a support structure and a carrier assembly. The support structure includes a connection groove. The carrier assembly is configured to support a host system and/or a display device and includes a first connector. At least a part of the first connector is located in the connection groove and sliding in the connection groove. An angle between the host system and/or the display device and the support structure is adjusted in a first direction and/or a second direction by sliding the first connector in the connection groove.

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.
