A dual key ring consisting of a ring holder, a first ring and a second ring is disclosed. The ring holder includes a connection tube with a ring hole transversely cut through one end thereof for securing the first ring, a movable block axially movably mounted in the connection tube with a round hole thereof for axial alignment with the ring hole, a locating block mounted in the connection tube, a first elastic member stopped between the movable block and the locating block, a movable cylinder coupled to the connection tube, steel balls rotatably mounted in ball holes around the movable cylinder and rotatably positioned in an inner annular groove in the connection tube, a connection rod mounted in the movable cylinder and stopped against the locating block, a connector coupled to the movable cylinder for securing the second ring and a second elastic member supported between the connection rod and the connector.

An item holder, mountable by suction on a mounting surface, including a deformable body having a convex outer surface that is substantially free of protrusions, a concave inner surface, and an edge extending around the outer and the inner surfaces. The deformable body is shaped to form in the body an elongate void extending through the deformable body, between the concave inner surface and the convex outer surface, in a direction that is generally parallel to the mounting surface during use of the holder. The elongate void formed by the deformable body terminates at opposing openings including of a first opening opposite a second opening. The body also defines a suction portion needed for creating the suction between the body and the mounting surface. The holder also includes a link component extending into the first opening, through the elongate void, and out of the second opening.

A system and method are provided for determining location information of a vehicle keyfob relative to an object. The system and method may include communicating with a primary device (e.g., a smartphone) having primary device authentication information with respect to the object, and receiving parameter information, such as keyfob authentication information, from the primary device.

A linking element for a modular jewel includes a single and continuous body showing at least one first portion, at least one second portion and at least one third portion, wherein at least one section of the at least one first portion is in close proximity to at least one portion of the at least one second portion, the at least one first portion, the at least one second portion and the at least one third portion delimiting between them at least one first through-opening through the body, wherein the at least one first portion and the at least one second portion are separated from each other by the at least one split selectively expandable/shrinkable to delimit/occlude an access passage to the at least one through-opening.

Provided herein is a low-profile key ring including a planar body including first and second inflection points, a connecting section extending between the first and second inflection points to define a concave indentation of the planar body, and a split disposed in the connecting section to define an outer segment and an inner segment of the connecting section, wherein the outer segment and inner segment are complementarily contoured.

A method for forming a double-sided loop strap includes: receiving a continuous longitudinal strip of loop material including a strip-form base bearing a field of upstanding loops on a fastening side of the strip bounded by opposite longitudinal edges, folding each of the longitudinal edges away from the fastening side, such that the base overlaps itself, and securing the folded edges in place by permanently bonding together overlapped areas of the base to form the double-sided loop strap.

A dual-entry keyring includes a ring body in a two-turn ring shape design, defining a first end and a second end respectively disposed at opposing top and bottom sides thereof beyond superimposition and a first press portion and a second press portion arranged between the first end and the second end to face toward each other and respectively outwardly curved so that a gap is defined between the first press portion and the second press portion. Further, the part of the first turn of the two-turn ring shape design of the ring body beyond the first press portion is closely abutted to the part of the second turn of the two-turn ring shape design of the ring body beyond the second press portion so that a stress point is formed at each of two opposite lateral sides of the gap between the first press portion and the second press portion.

A key fob for retaining a key or other object, including: a body structure manufactured from a printed circuit board material; a key ring structure manufactured from the printed circuit board material coupled to the body structure; and a conductive loop disposed one or more of within, on a surface of, and coupled to the printed circuit board material of the key ring structure. Optionally, the body structure and the key ring structure are integrally formed from the printed circuit board material.
