The stand may be completely passive and use conductive antenna elements and passive resonance matching circuit elements to provide efficient coupling. In another aspect a thin profile passive keyboard adapted for use with a near field enabled tablet is provided. In another aspect a mounting bracket or holder, embedded antenna, and passive keyboard combination is provided adapted for converting a tablet into a notebook type configuration.

Provided is a closure device including a first closure part that includes a locking element, a force transmission element operatively connected to the locking element, which can be loaded along a force direction, and an actuating element movable relative to the locking element, and a second closure part that includes an engagement element. The locking element and the engagement element can be attached to each other for connecting the first closure part and the second closure part to each other and are connected to each other in a closed position. In the closed position, when the force transmission element is loaded along the force direction, the locking element is loaded in a locking direction towards contact with the engagement element by the action of force of the force transmission element. The actuating element can be actuated in order to adjust the locking element against the locking direction.

A mounting assembly includes a mounting block. A first shaft is supported by the mounting block and movable about a first rotational axis and a first extension axis with respect to the mounting block. A second shaft is coupled to the first shaft and movable about a second rotational axis.

A track dolly to mount a camera and accessories thereon is provided. The track dolly includes a steering mechanism to enhance directional control of the dolly when in motion. The track dolly includes a plate, at least one rail coupled to the plate and designed to permit attachment of the camera or accessories thereto, a plurality of wheels rotatably mounted to the plate, a handle rotatably mounted to the plate, and a plurality of linkage members adjustably mounted to the bottom surface of the plate and operably connected to the handle. The linkage members are operably connected to any number of the plurality of wheels. The handle is maneuvered to permit the plurality of linkage members to rotatably adjust any number of the plurality of wheels relative to the plate, thereby adjusting the directional control of the dolly.

A method for controlling a gimbal configured to carry a load includes detecting a motion state of a motion of the gimbal or the load, comparing the motion state to a preset threshold to obtain a comparison result, and controlling the gimbal to maintain the load in an original posture based on the comparison result.

A display device can include a display; a mounting bracket coupled to a rear surface of the display; a first arm connected to the mounting bracket for tilting the mounting bracket up and down; a second arm connected to an end portion of the first arm and the first arm being configured to rotate based on a first swivel shaft disposed in the second arm; a third arm connected to an end portion of the second arm and rotates based on a second swivel shaft disposed in the third arm; a pillar connected to the third arm and the pillar being configured to move up and down; and a fixing part configured to be fixed to an external object, in which the pillar is connected to an upper surface of the fixing part and rotates based on a third swivel shaft disposed in the fixing part or the pillar.

A crossbar assembly for facilitating isolation of a sensor assembly from vibration of a payload mounting system on a vehicle comprising an outer crossbar segment, an inner crossbar segment, an isolator, and a damper. The outer crossbar segment comprises a payload mount interface operable to mount to a payload mount, and an outer isolator interface operable to mount to an isolator. The inner crossbar segment comprises a structure interface to mount to a structure, and an inner isolator interface operable to mount to the isolator. The isolator can be supported by the outer and inner crossbar segments. The damper is adjacent the isolator. The isolator is operable to deform in response to relative movement between the outer and inner crossbar segments. The isolator operates to partially decouple the outer crossbar segment from the inner crossbar segment and the damper dampens vibrations propagating between the outer and inner crossbar segments.

A dynamic balance type vertical vibration isolator includes slide blocks, balance springs, mass blocks, a fixed block, rotation shafts, stiffness-adjustable springs, etc. When an earthquake force is upward, the stiffness-adjustable springs are compressed, upward forces of the stiffness-adjustable springs are increased, meanwhile, the slide blocks and the mass blocks move away from the fixed block, the balance springs are stretched to generate pull forces, and the pull forces have vertically upward components, so as to reduce compression degrees of the stiffness-adjustable springs, and further to reduce the upward forces of the stiffness-adjustable springs. Similarly, when the earthquake force is downward, the stiffness-adjustable springs are stretched, downward forces of the stiffness-adjustable springs are increased, meanwhile, the slide blocks and the mass blocks move close to the fixed block, the balance springs are compressed to generate compression forces, and the compression forces have vertical downward components.

A lifting support device that includes a linear actuator including a first end configured to support an object, and a load sensor positioned to determine application of a first load on the load sensor by at least the object. The linear actuator is maintained in equilibrium when supporting the first load. The lifting support device further includes a controller coupled in communication with the load sensor, and the controller is configured to selectively actuate the linear actuator in response to application of a second load on the load sensor.
