Abstract: Disclosed are an interconnected system and an interconnected device for an outdoor activity group that are capable of transmitting RF signals by a public open frequency band and transmitting a data packet in a relay manner without requiring the internet and external communication devices. The data packet includes the positioning information of a machine and each interconnected device, and each member of the outdoor activity group acts as a relay station to unlimitedly extend the communication distance of the whole group in a relay manner, so as to overcome the problem of losing contact caused by a long distance and a failed receipt of signals, and the interconnected system and device can improve the safety of outdoor activities.

Abstract: A barrette includes two decorative elongate plates of the same structure combined together. Each decorative plate has an insertable end portion, a two-holed end portion and an intermediate twisted portion. One decorative plate has its insertable end portion with two projections extending in the two holes portion of the other decorateive plate, with the intermediate portions intertwisting and overlapping with each other so that the two decorative elongate plates may be combined together in a stabilized condition, with the two projections respectively stopped by an upper edge and a lower edge of the two holes.

Abstract: A barrette consists of a decorative elongate chain-shaped frame and a decorative elongate strip inserting up and down through decorative holes continually provided in the frame and resting on an upper or lower surface of contact walls separating each two decorative holes of the frame. The frame and the strip may have the same length and width but different colors from each other.
