A removably mounted wheelchair lift device that can elevate the wheelchair and its user. The lift device has a novel lifting mechanism which has an upper plate, a lower plate, a knee plate, an upper interior link, an upper exterior link, a lower interior link, a lower exterior link and a transfer link. The various parts of the lifting mechanism are pivotally attached to one another in a manner which provides a linear and precise extension and retraction. Extension and retraction of the lifting mechanism is achieved by a rotary electric motor and gear drive which introduce a torque between adjacent parts of the lifting mechanism. The lifting mechanism maintains a parallel relationship between its top and bottom plates throughout its range of motion. The lift device may also be used in other applications where the level or angle of the equipment or surfaces being supported must remain constant regardless of height. Other applications may include, but are not limited to, supporting hospital beds, medical operation tables, manufacturing work stations, office work stations, pallet stand, and other warehouse and storage applications.

A mounting system capable of mounting objects to support structures is disclosed. The mounting system includes a wall mount including a display bracket configured to hold the object, a fixed support bracket couplable to a vertical support structure, and a linkage assembly. The linkage assembly has a low-profile stowed configuration in which the object is held in a raised position close to the support structure. The linkage assembly moves to another configuration to move the object. The object can be held in a lowered position. A pinion adjustment mechanism can be used to control a biasing mechanism for facilitate convenient movement of the object.

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 multifunctional apparatus to lift and support a computing device includes a base assembly, an oblique arm assembly, a power arm assembly, a head assembly, and a board assembly. The base assembly is adaptable to secure with a platform. The oblique arm assembly is pivotally connected with the base assembly. The power arm assembly is pivotally connected with the oblique arm assembly. The head assembly having a proximal end, and a distal end, wherein the proximal end is pivotally connected with the power arm assembly. The board assembly is rotatably connected with the distal end of the head assembly. The board assembly is adaptable to securely support the computing device.”

Knuckle joint assembly for a medical device support system. The knuckle joint assembly includes a cartridge assembly that includes a cartridge housing and a rotary bearing. The cartridge housing includes a bore having a central axis and a bearing mount in the bore. The rotary bearing is press fitted in the bearing mount and configured to receive axially therethrough a spindle to rotatably support the spindle about the central axis. The knuckle joint assembly includes a retaining clip and a retaining pin. The retaining clip is selectively movable to disengage and engage a groove in a spindle to respectively support or release the spindle along a central axis. The retaining pin is movable between a first position to allow movement of the retaining clip between positions but prevent removal of the retaining clip, and a second position to block movement of the retaining clip from the engaged position.

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.

The description relates to cooperatively controlling devices based upon their location and pose. One example can receive first sensor data associated with a first device and second sensor data associated with a second device. This example can analyze the first sensor data and the second sensor data to determine relative locations and poses of the first device relative to the second device and can supply the locations and poses to enable content to be collectively presented across the devices based upon the relative locations and poses.

The present disclosure provides a display screen bracket. The display screen bracket includes a first support body configured to carry a display screen, a second support body disposed opposite to the first support body, and a first linkage mechanism configured to connect the first support body to the second support body. By means of linkage of the first linkage mechanism, a display screen is swingable about a first axis of the display screen. In this way, watching requirements for different positions and angles are satisfied.

Improved support structures and systems are disclosed for installing tablet devices, display screens, flat screen monitors, or medical devices within a wide variety of environments. A core arm extends from a rear end, toward a front end, in which the rear end is configured to be pivotably mounted either directly to a mount structure, or to an extension arm that in turn is mounted to a mount structure. The front end is configured to be pivotably mounted to a front-end panel mount structure. The structures and systems can be configured for light or heavy configurations, with or without the use of an extension arm, and can provide fully concealed cable routing, in which one or more cables are readily accessible, via snap fit covers, for easy installation and maintenance, which can provide a clean structure that can readily be serviced and cleaned as desired.

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.
