An expandable socket for attachment to a mobile electronic device. The expandable socket includes a platform adapted to engage a portion of the portable media player, a skin coupled to the platform, wherein the skin is deformable between a collapsed configuration and an expanded configuration. The expandable socket includes a button coupled to the skin opposite the platform. The expandable socket also includes a biasing element arranged within the skin between the platform and the button, the biasing element configured to bias the skin into the expanded configuration.

An expandable socket for attachment to a portable media player or a portable media player case. The expandable socket generally includes a platform, a skin coupled to the platform, a button coupled to the skin opposite the platform, and a biasing element. The skin includes an outer wall, an inner wall spaced radially inward of the outer wall, and a cavity defined by the inner wall, wherein the skin is deformable between a collapsed configuration and an expanded configuration. The biasing element is arranged within the cavity of the skin between the platform and the button, such that the biasing element is at least partially surrounded by the inner wall of the skin. The biasing element is configured to bias the skin into the expanded configuration.

An expandable socket for attachment to a portable media player or a portable media player case. The expandable socket generally includes a base, a button, and a spring. The base is adapted to engage a portion of the portable media player or the portable media player case. The button is spaced from and movable relative to the base. The spring is disposed between the base and the button, the spring arranged to resist movement of the button toward the base.

A projector suspension device comprising a base fixed to a wall, a support member extending from the base and supporting the projector, and an adjustment mechanism that adjusts a tilt and position of the projector, the adjustment mechanism including a first member that slides with respect to the support member in a first direction perpendicular to the wall and adjusts the position of the projector in the first direction, a second member fixed to the first member, a third member connected to the second member, a fourth member connected to the third member and that rotates with respect to the third member about an axis parallel to the wall and perpendicular to the first direction, and a turning member that adjusts a rotation of the fourth member about the axis by rotation of the turning member, wherein a rotating pivot of the turning member is perpendicular to the base.

A support for an imaging device includes a first rotatable assembly supportable by a support that rotates in a generally horizontal plane and a horizontal locking member. The imaging device includes a second rotatable assembly that rotates in a generally vertical plane. Imaging device includes an interconnection structure that interconnects the first rotatable assembly to the second rotatable assembly such that the second rotatable assembly is rotatable around the first rotatable assembly at an elevation higher than the first rotatable assembly and offset laterally from the first rotatable assembly. Imaging device includes the first rotatable assembly including a panning structure that rotates the support in the generally horizontal plane and a leveling base that is rotatable in a non-coplanar manner relative to the panning structure.

A shipping strap assembly protects the isolator mechanism of a vibratory screening machine against exceeding its elastic limits. The isolator mechanism is pivotally connected between shafts on the machine frame and the machine basket. The protective assembly includes a distally narrowing boss on at least one of the shafts. A rigid strap has two apertures, one contoured to receive and ride on the boss and the other contoured to receive the other shaft, spaced to maintain the distance between the shaft axes within an elastic limit of the isolator mechanism. The narrowing boss provides leeway for easy manual alignment of the mechanism shafts with the strap apertures, and the narrowing boss and contour of the other aperture facilitate restoration toward its normal load length, of an elastically distorted mechanism.

A load-adjustable display support device includes a support frame having opposite frame top and bottom ends, a sliding unit slidable along the support frame, and a load-adjusting unit disposed between the sliding unit and the support frame and including at least one tension spring and an adjustment member. The at least one tension spring can generate a tension force to bias the sliding unit to move between upper and lower limiting positions, where the sliding unit is proximate to the frame top and bottom ends, respectively. The adjustment member is disposed on the support frame and is operable to move a spring top end of the at least one tension spring along the length of the support frame for adjusting a tension of the at least one tension spring.
