A protection apparatus for an appliance supported by a tripod, the protection apparatus including: a tilt sensor, for alerting upon tilting of the tripod; and an airbag inflated upon the alerting for protecting the appliance. The airbag is shaped to comprise at least one of three protrusions, projected outward upon airbag inflation, each protrusion being directed in one of the common tilting directions perpendicular to and towards an imaginary line between feet of two tripod legs.

A security apparatus for securing a portable electronic device includes a base that defines a cavity extending from a first end of the base to a second end of the base. A holder is structured to engage the base. The holder includes an outer surface defining a plurality of channels terminating at a support surface and a holder groove defined on the outer surface of the holder. The security apparatus further includes a securing portion with a plurality of projections that are each structured to contact the support surface and engage one of the holder grooves. Rotation of the securing portion relative to the holder acts to move at least a portion of each of the plurality of projections into the holder channel and secure the securing portion to the holder, where the portable electronic device is secured between the securing portion and the holder.

A panoramic device includes a base member and a clamp member rotatably interconnected within a single plane of rotation with the base that includes a first rotatable knob to selectively inhibit the rotation of the clamp member with respect to the base. The upper surface includes a central region that is at a different elevation than another portion of the upper surface. The clamp includes a pair of opposed surfaces suitable to detachably secure a camera thereto. The one of the opposed surfaces is maintained in a fixed relationship with respect to the clamp member. The other one of the opposed surfaces is in a movable relationship with respect to the clamp member using a second rotatable knob. The first knob and the second knob are rotatably connected with respect to one another.
