Display and audio systems and methods for controlling positioning of displays and speakers based on viewer and listener attention are disclosed. According to an aspect, a display system includes a selectively adjust a viewing angle of a display for one or more viewers. The display system also includes a motorized mechanism that controllably positions the display in one of the positions. An attention detection system is configured to acquire movement and position data of the viewer(s). The attention detection system is also configured to determine whether attention of the viewer(s) is directed to the display based on the acquired data. Further, the attention detection system is configured to control the support assembly to adjust the viewing angle of the display for viewing by the viewer(s) in response to determining that the attention of the viewer(s) is directed to the display.

A leaning vehicle includes a body frame, a steered wheel and a non-steered wheel, a motor, a left-right-tilt-angle-detection-section, and a control device that controls the motor to apply a steering force to the steered wheel. The steering force steers the steered wheel to turn the leaning vehicle rightward in a case where the body frame tilts rightward, and steers the steered wheel to turn the leaning vehicle leftward in a case where the body frame tilts leftward. Alternatively, the steering force steers the steered wheel to turn the leaning vehicle leftward in the case where the body frame tilts rightward, and steers the steered wheel to turn the leaning vehicle rightward in the case where the body frame tilts leftward.

A spatially positioned assembly comprising, in preferred embodiments, first and second boom sections concatenated in articulated fashion to a turret at a proximal end thereof, and rotatably connected with a fluid connection adapter at a distal end thereof. The fluid connection adapter is preferably configured for connection to a mating fluid connection housing assembly provided on a wellhead. Independent control of rotation at each of multiple axes on the spatially positioned assembly allows an operator to establish corresponding desired spatial positions for the spatially positioned assembly.

A spatially positioned assembly comprising, in preferred embodiments, a fluid inlet in fluid flow communication with a fluid connection adapter. A plurality of boom sections are concatenated in articulated fashion. The plurality is rotatably connected to a turret at a proximal thereof, and is rotatably connected with the fluid connection adapter at a distal end thereof.
