An autonomous mobile device has a tower extending from a main body. The tower pans from left to right. An extensible mast may extend through, and pan with, the tower. An upper section is attached to the tower by a hinge and may tilt with respect to the tower. The upper section may include a touchscreen or other devices. An assembly with separate pan and tilt motors allows for the tower and attached upper section to pan while also allowing the upper section to tilt independently of the panning motion. The tilt motor is within the portion of the assembly rotated by the pan motor. The tilt motor drives a worm gear in the tower to rotate a tilt axle. An asymmetric friction hinge connects to the upper section to the tilt axle. Rotating the tilt motor rotates the worm gear, rotating the tilt axle and the attached upper section.

A pneumatic telescopic column assembly for supporting and moving military equipment, communication equipment, lighting equipment and/or surveillance equipment is provided. The pneumatic telescopic column assembly extends along an axis and has a plurality of tube groups telescopically configurable between a compact configuration and an extended configuration. The plurality of tube groups has a base tube group, an intermediate tube group and a head tube group. The base tube group has a base tube element and a base locking ring that has at least one horizontal latch, at least one actuator and at least one vertical latch. The intermediate tube group has an intermediate tubular element and an intermediate locking ring that has at least one horizontal intermediate latch. The tubular head group has a tubular head element.

A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.

The tie rod assembly union includes a tube sleeve and a tie rod shaft that extends into the tube sleeve such that the tie rod shaft and the tube sleeve overlap with one another. In the overlapping area, each of the tie rod shaft and the tube sleeve has at least one set of openings. A C-shaped clamp is disposed about the tube sleeve. The clamp has a curved inner surface which engages both tube sleeve halves. The clamp has a first set of apertures which are spaced outwardly from the curved inner surface and a second set of apertures which extend to the curved inner surface. A first fastener extends through the first set of apertures to tighten the clamp onto the tube sleeve. A second fastener extends through the second set of apertures and through aligned openings in the tie rod shaft and tube sleeve.

A connector system for an aircraft, for connecting a hose line, includes a skin panel which has a clearance which extends between an external face and an internal face, a primary part which on the clearance is disposed on an internal side of the skin panel that is defined by the internal face, a cover mounted on the primary part and movable between a closing position in which the cover covers the clearance of the skin panel, and an opening position in which the cover releases the clearance of the skin panel, and a tubular connector port mounted on the primary part and movable between a storage position in which the connector port is disposed on the internal side of the skin panel, and a use position in which the connector port projects beyond the external face of the skin panel.

In an aspect, provided is an adjustable telescoping assembly. The adjustable telescoping assembly comprises a first support member and a second support member that is slidable upon the first support member and which defines an interior volume. At least one damping element is provided that extends from outside the second support member, through a corresponding damping element aperture on the second support member into the interior volume and engages the first support member.

The disclosed apparatus, systems and methods relate to an improved extendable and rotatable shovel for use in various applications such as the shoveling of snow. Users can modify the shovel to accommodate their stature and personal preferences.

First teeth of a first tooth member that moves together with an upper jacket mesh with second teeth of a second tooth member. The second tooth member includes a received portion received by a receiving surface of a receiving member (energy absorption member). The second tooth member is rotatably supported by a fulcrum that is formed on the receiving surface at a contact position between the receiving surface and the received portion and is movable in a column axis direction. A guide shaft supported by a support member that is supported by a lower jacket is inserted into an elongated hole of the second tooth member, thereby guiding the second tooth member in a meshing and unmeshing direction.
