Abstract: Devices and systems for producing rotational actuation are described. More specifically, hydraulic and pneumatic actuators that can produce and control rotational or joint-like motion are described. An actuator may be configured to allow parallel coupling of multiple actuators, and thus increase the range of rotation of the actuators when considered collectively.

Abstract: An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.

Abstract: An apparatus that supports a person in a variety of positions so that a tattoo artist can comfortably apply a tattoo to the skin of the supported person is herein disclosed. The apparatus can be articulated to cause a person's legs and arms to be optimally positioned and supported to receive a tattoo.

Abstract: A device for accessing tissue within a body lumen comprises an elongated body portion defining a lumen and an anchoring mechanism including an expanding structure on a distal portion of the elongated body portion. The anchoring mechanism moves the expanding structure from an insertion configuration in which the expanding structure is constricted against the device to an operative configuration in a body in which the expanding structure expands away from the device without altering a length of the anchoring mechanism in combination with a control mechanism for selectively engaging the anchoring mechanism.

Abstract: An adjustable chair can support an occupant that sits on a front portion of a seat cushion. When the user leans back, the chair can provide back support without requiring that the user slide rearwardly along the seat cushion, thereby providing back support to minimize, limit, or substantially eliminate lower back fatigue, discomfort, or the like. A back support of the chair can be located at a desired forward/rearward position based on the user's position on the seat. In some settings, the chair can be used by a card dealer who tends to sit on a forward portion of the seat when dealing cards. The back support can be positioned to comfortably support the dealer's back when, for example, the dealer sits generally upright. The chair can also be used by other individuals that frequently sit on the front of the seat cushion.

Abstract: A cap assembly can include a cap holder device with a plug member and a cap holder. The cap holder device is positionable in an end of a conduit positioned along a roadway. The cap holder is carried by the plug member and includes a magnetic element and a connector. The connector is connectable to the magnetic element to the plug member such that the magnetic element is movable relative to the plug member so as to position the magnetic element for releasably holding a cap that covers the end of the conduit when the plug member is positioned in the conduit. The cap assembly can be a debris cap insertable in a conduit, an end of a pipe, or other opening.

Abstract: A golf tee toss system for deciding the order of play in a game of golf. The golf tee toss device is grasped by a protruding edge and tossed to the ground. The numerals located on the surface of the golf tee toss device indicate the order in which the golfers will tee off to start a round of golf. The golf tee toss device can be used over and over for different rounds of golf. The indicium on the golf tee toss device can be in a plurality of designs to promote collection of the golf tee toss device.

Abstract: Devices and systems for producing rotational actuation are described.

An actuator may be configured to allow parallel coupling of multiple actuators, and thus increase the range of rotation of the actuators when considered collectively.
