A crossbow includes a body includes a connection part that includes a clamping portion. The clamping portion includes two side plates, and a space is formed between the two side plates. A bow unit includes a bow and a block which is formed to the middle portion of the bow. The block includes a protrusion which is accommodated in the space and clamped between the two side plates so as to connect the bow unit to the connection part. A magazine includes the first end thereof pivotably connected to the body, and the second end of the magazine is connected to the clamping portion. The magazine includes two lugs between which the clamping portion is located. A pin extends through the two lugs, the two side plates and the block to connect the magazine to the body. By removing the pin and pivoting the magazine, the bow unit is replaced.

A folding device for an archery weapon, in particular for a crossbow, includes a shaft connecting section, having two limbs, each of which has a free end and a shaft-side end pivotably mounted on the shaft connecting section, with two locking pawls, each of which is pivotably mounted on the shaft-side end of the shaft connecting section, which are each pivotably mounted on the shaft connecting section. The pawls are pivotably arranged in such a way that the limbs can each be secured in a closed position of the respective pawls for unfolding and/or clamping a bow and in an open position of the respective pawls the limbs are each released for folding.

An adjustable limb pocket of an archery bow includes a pocket insert having at least one channel that extends along a length of the pocket insert. The at least one channel can include a plurality of attachment positions. A limb contact member can be coupled to one of the plurality of attachment positions to support a bow limb retained within the limb pocket. One or more limb contact members can be repositionable within one or more channels of the pocket insert to vary a bowstring tension of the archery bow and/or manipulate the movement a distal tip of the bow limb as the bowstring is drawn and released. In some cases, one or more weights are positioned inside the limb pocket.

A modular survival tool including a tool body having a tomahawk axe selectively disposed on a top end thereof, a storage compartment therein, a pair of forward protrusions to which a pair of limb members forming a bow are selectively mounted for storage, a pair of angled rearward protrusions are disposed on a rear side of the tool body and the limb members attached thereto to form the bow, and a bow string attached to upper ends of the rearward protrusions. A modular arrow has connectable components stored within the storage compartment but assemble into an arrow for use with the bow. At least one arrow rest is disposed on one of a right side and a left side of the tool body to assist in aiming the arrow. A fire starting surface is disposed on a removable cap over the bottom end, which provides access to the storage compartment.

The invention relates to a method for segmenting and indexing features from multidimensional data, said method comprising the steps of inputting (201) a sequence of tuples in a transformation process, first mapping (204) the tuple sequence to a sequence of hash sums with a rolling hash function, grouping (205) the sequence of tuple hash sums into a sequence of overlapping and contiguous sequences of n tuples hash sums, second mapping (206) of the resulting sequence of n tuples hash sums to a sequence of n-gram hash sums, and segmenting (207) the sequence of n-gram hash sums into chunks of tuples using a segmentation method selected in the group comprising at least one Content-Defined Chunking and Winnowing.

A bow limb retaining assembly comprises a limb and a retainer having a cavity for receiving the limb. The retainer comprises opposed lateral surfaces, a first abutting surface arranged to contact a compression surface of the limb and a second abutting surface arranged to contact a tension surface of the limb. A first length portion of the retainer includes the first abutting surface and excludes the second abutting surface, and a second length portion of the retainer includes the second abutting surface and excludes the first abutting surface.
