Disclosed is an articulated support arm for an elongated flexible medical instrument, including: a segment rotating about an axis of rotation, a radial brake for preventing rotation of the segment about the axis of rotation, including: a supply of hydraulic fluid, a piston whose stroke along the direction of the axis of rotation, due to the pressure of the hydraulic fluid, prevents rotation of the segment about the axis of rotation, the piston being an annular piston having a hollow center about the axis of rotation, the supply of hydraulic fluid passing through the hollow center.

A display apparatus including a display, and a support member including a fixing member to be fixed to a wall surface, a mounting member on which the display is to be mounted and connected to the fixing member, and a connector attaching the mounting member to the fixing member and supported for rotation in forward, backward, leftward, and rightward directions, in which the connector includes a plurality of rotatable supports connected to the fixing member and supported for rotation in the leftward and rightward directions, a plurality of movable supports connected to the rotatable supports and supported for slidable movement in the leftward and rightward directions, and a plurality of connecting supports connected to the mounting member and supported for rotation in the forward and backward directions, and connected to the movable supports to rotate in the leftward and rightward directions.

An apparatus includes a head portion, an undercarriage portion, and a telescopic portion configured to adjustably move into a plurality of different lengths. A first end of the head portion is rotatably attached to a first end of the undercarriage portion and a second end of the undercarriage portion is rotatably attached to a first end of the telescopic portion. A second end of the head portion is rotatably attached to a second end of the telescopic portion. In a first position, the telescopic portion has a first length of the plurality of different lengths and the head portion and the undercarriage portion form a first angle. In a second position, the telescopic portion has a second length of the plurality of different lengths and the head portion and the undercarriage portion form a second angle different from the first angle.

Embodiments relate to a cellphone self-standing device that allows any cellphone to stand in position and angles that are more suited for selfie and two way video communication. The device of this invention integrates with the cellphone such that it can be carried around easily, the same way that cellphones are; store with the cellphone in where cellphones are normally stored; and operate on demand with minimal set up, to facilitate ease of use.

A support system for a display device includes a first arm configured to extend from a support surface. A second arm is rotatably connected to the first arm. The second arm has a range of movement relative to the first arm. A tilt head is rotatably connected to the second arm and configured to connect to a display. A first biasing member is positioned in the second arm and configured to provide a first counterbalancing force to the second arm to offset a load of the display. A second biasing member is positioned in the second arm and configured to provide a second counterbalancing force to the second arm to offset the load of the display. A lockout mechanism is configured to disengage the second biasing member and eliminate the second counterbalancing through at least a portion of the range of motion.

A coupling system for peripheral devices may include a housing and a shaft assembly. An end of the shaft assembly is threaded and couples to and uncouples from a peripheral device by relative rotational movement between the peripheral device and the shaft assembly. An inner cavity of the housing and another end of the shaft assembly defines a limited range of rotational motion between first and second rotational positions. Rotating the shaft assembly to the first rotational position allows for the peripheral device to be rotated relative to both the shaft assembly and the housing to couple the peripheral device to the housing via the shaft assembly. With the peripheral device coupled to the shaft assembly, relative rotational motion between the peripheral device and the housing is allowed between the first rotational position and the second rotational position without rotating the peripheral device relative to the shaft assembly.

A foldable bracket moveable between opened and folded positions. The foldable bracket including first and second bracket arms rotatably coupled to each other, where the second bracket arm includes a second bracket arm slot, a bracket arm linking member rotatably coupled to the first bracket arm and slidably coupled to the second bracket arm, first and second pins slidably disposed in the second bracket arm slot, where the second pin slidably couples the bracket arm linking member to the second bracket arm, a pin connecting member having an aperture and a pin connecting member slot, where the second pin is disposed in the aperture and the first pin is slidably disposed in the pin connecting member slot, and a release lever rotatably coupled to the second bracket arm and adapted to rotate between first and second positions.

A supporting apparatus and a display device are disclosed. The supporting apparatus is configured for supporting an external apparatus, and includes: a bracket supported on a supporting surface and having a waist-shaped hole; and a rotating member with one end passing through the waist-shaped hole and the other end connected to the external apparatus. Under action of an external force, the rotating member is slidable and rotatable relative to the bracket in the waist-shaped hole. When the external force disappears, the rotating member remains stationary relative to the bracket.

A supporting and fixing structure and a photovoltaic tracking and mounting system. The supporting and fixing structure includes a main support rod, a mounting rod, a rotary power device and a plurality of auxiliary support rods. The mounting rod is rotatably mounted on the main support rod through the rotary power device. The auxiliary support rods are rotatably matched with the mounting rod. The auxiliary support rod is configured to support the mounting rod. It further includes a valve stem, a housing, an inner housing plate and a plunger rod. The inner housing plate is disposed in the housing, and separates a space in the housing to be two chambers. The plunger rod is movably installed on a housing wall of the housing, and is configured for blocking or communicating the first housing chamber. The valve stem is in sliding and sealing fit with the second housing chamber.

An apparatus includes a head portion, an undercarriage portion, and a telescopic portion configured to adjustably move into a plurality of different lengths. A first end of the head portion is rotatably attached to a first end of the undercarriage portion and a second end of the undercarriage portion is rotatably attached to a first end of the telescopic portion. A second end of the head portion is rotatably attached to a second end of the telescopic portion. In a first position, the telescopic portion has a first length of the plurality of different lengths and the head portion and the undercarriage portion form a first angle. In a second position, the telescopic portion has a second length of the plurality of different lengths and the head portion and the undercarriage portion form a second angle different from the first angle.
