Drone systems can include one or more drones that can fly. A drone can include a camera system that has one or more cameras. Drones can fly over an avalanche zone where an avalanche recently occurred to search for avalanche victims and mark the locations of avalanche victims to quickly and accurately notify people where to dig through the snow to save avalanche victims from asphyxiation.

An anchoring and support device for climbing, suitable for being connected to a safety rope, comprises at least two opposite first cams, rotatably hinged to a rotation pin and suitable for operating by exchanging forces along a first line crossing the points. The cams may contact opposite walls of a crack or fissure in a rock. Movement means of the rotation pins are adapted to increase an extension distance of the cams between a minimum size limit position and a maximum size limit position. Locking means for the movement means are adapted to lock the rotation pins in a fixed position and include one or more stabilizing means provided with movement means and locking means. The stabilizing means are adapted to operate according to an exchange of forces along a second line crossing at least one further contact point with the walls.

An improved camming stem system including a head member, a plurality of cam lobes, a connection system, and a retraction system. The cam lobes may be selectively rotatable between an extended state and a retracted state with respect to at least one axle of the head member. The connection system may create an elongated, substantially rigid region by intercoupling the head member with a loop. The connection system is configured to create an elongated partially rigid region by intercoupling the head member with a loop, wherein the connection system comprises a twisted cable coupled between the head member and the loop, and wherein the loop is oriented substantially parallel to the at least one axle, and wherein the twisted cable includes a twisting radial angle of at least 90 degrees.

A convertible backpack that can be used as an edge protection mat to protect ropes against abrasion and includes a flexible mat or sheet that can be configured into a pack and carried on the back of a user to carry equipment, clothing, or other gear. A pair of rope protection members are affixed to the outer surface of the sheet for carrying the pack and are easily removable for use alone or in combination with the flexible sheet to further protect ropes.

A training apparatus for mountain climbers. The training apparatus includes a base portion and a ring member. The ring member extends substantially perpendicular from the base portion. The training apparatus can also include an attachment mechanism secured to the base portion for securing the training apparatus to a surface.

A belay device (100) for braking and/or blocking at least one rope (10) including a main body (1) having at least two main walls (2, 3) arranged facing and spaced from one another so that to form a space between them. and at least one friction element or surface (12); said at least one rope (10) being arranged between said braking element (15) and said friction element or surface (12) when said braking element (15) is in said braking/blocking position of the rope.

An automatically braking belay device for use in belaying climber or descending with a rope, using the pull of the rope to activate braking by the roll of the cam within the frame of the device. An adaptive release lever unjam the rope to release with closing mechanism utilizing magnets for practically permanent and fail safe closure.
