A climbing system includes a treestand and a plurality of climbing sticks. The treestand includes a monolithic platform formed from strengthened material. Each of the climbing sticks includes a frame having a plurality of weight-reduction apertures formed therethrough. Tree engaging structures include ramped surfaces to facilitate smooth downward sliding on a tree. Methods of manufacturing a treestand and climbing sticks are also disclosed. The method of manufacturing a treestand includes providing a solid, strengthened piece of material and removing portions of the material to form openings between structural supports. The method of manufacturing a climbing stick includes providing a frame and forming a plurality of weight-reduction apertures therethrough.

A method for producing one or more concave cut-outs on a main body, which is in particular substantially cylindrical, more particularly one or more grooves on a magnetic armature, a push rod, or a magnetic keeper plate, includes the following steps: providing a main body, which is in particular substantially cylindrical and has a first axis of rotation, rotating the cylindrical main body around the first axis of rotation in a first rotational direction by means of a lathe, and rotating a striking tool, which is provided with a number of fly cutters, around a second axis of rotation, which extends in parallel and offset in relation to the first axis of rotation in a second rotational direction, which is opposite to the first rotational direction, in such a way that the fly cutter engages in a material-removing manner in the main body to produce the cut-out.

A liquid reservoir includes a housing and a cover hermetically fixed to the housing, and further includes a flow guiding pipe having one end connected with the housing, and a filter assembly arranged in the housing and including first and second position-limiting assemblies, a filter member, and a molecular sieve. The first position-limiting assembly includes at least a first position-limiting member having a bottom portion, first and second protrusions. A part of an outer side wall of the flow guiding pipe is limited by and in cooperation with an inner side wall of the first protrusion which is located on an outer peripheral side of the part of the outer side wall of the flow guiding pipe. An outer side wall of the second protrusion is located on an inner peripheral side of a part of an inner sidewall of the housing.

An element for an electronic device can include a metal exterior portion including a first material, an interior portion including a second, independently selected material, and an engagement feature formed on a surface defined by the exterior and interior portions. The engagement feature can mechanically engage a material molded to the surface. A method for forming an element for an electronic device can include joining a boss to a member, forming a feature in the member while orienting the member via the boss, and at least partially removing the boss to form the element. An electronic device can include a frame defining an interior volume of the device, a display component, a transparent cover positioned adjacent to the display component, and an encapsulating material at least partially surrounding the display component and joining the display component to the frame.

A method of forming a plurality of shaped piece parts from a sheet of material involves arranging a plurality of aligned workpieces into an optimized workpiece pattern, and arranging one or more series of joints that maintains the workpieces in rigid connection and alignment. The joints include one or more particular joints that have an axis of rotation, which permits a first section of the workpieces to be rotated about the axis of rotation with respect to a second set of workpieces to weaken and break the one or more particular joints. The method also involves applying one or more folds across the sheet of material to form one or more pluralities of aligned bends in at least some of the plurality of workpieces. The method further involves breaking the joints to rigidly decouple each of the plurality of shaped workpieces into individual piece parts.
