The current document is directed to methods and devices that facilitate object orientation. In particular, the current document is directed to methods and devices that facilitate tactile orientation of objects, such as connectors, keys, cards, and other objects that are manipulated by human users for insertion into complementary connectors, slots, and other receptacles. In addition to facilitating tactile orientation of objects, the devices and additionally provide mechanical advantage for objects insertion and removal and may additionally provide visual orientation indications, and other indications, to human users. The currently disclosed devices are tangible, physical objects or features that, when held, felt, and/or manipulated by human users, provide a tactile indication of the orientation of an engagement feature of an object is inserted into a complementary connector, slot, port, or other receptacle.

The present invention relates to a changeable combined mechanical key, belonging to the technical field of key structures of encryption locks. The changeable combined mechanical key includes a bracket detachably connected to an end of a key handle, and a protective cover detachably connected to the end of the key handle and a key-shaped component. The present invention achieves anti-theft and duplication-preventing purposes for a key, and has unique advantages in many important fields such as safety boxes, important military places, banks, household intelligent anti-theft locks, and any other fields that require secrecy security. Unlike an electronic key that is easy to cause a problem due to an electronic circuit device and software and so on, the present invention, which is irreplaceable and has changed a machining process of a traditional mechanical key, saves energy and reduces consumption, and has a broad application prospect.

A system and method for a key, comprising a key blade having a socket that releasably engages a key head. A method includes cutting an original key head from an original key, forming a socket onto a cut end of the key blade, and attaching a key head onto the socket.

A key includes a key-shaped supporting structure, made of a metal material, which includes a stem and a head having an opening therethrough, the opening being entirely laterally delimited by inner side walls extending from one face of the head to the other; and an insert, made of a polymeric material, which includes an identification system and which is removably inserted into the opening of the head, the insert having at least one section protruding from the inner side walls of the opening and laterally projecting with respect to the opening, thus abutting against a part of the head portion provided about the opening.

Some of the inventive concepts described herein include a data key having a computer readable medium containing information indicative of a bitting pattern for a master key. The bitting pattern on the data key may be downloadable to a key cutting device to cut a duplicate key that has the same bitting pattern as the master key. In addition, a method of creating a data key is also provided herein. The method includes identifying a type of key; identifying a bitting pattern; and storing the type of key blank required and bitting pattern to be cut in the key blank on a computer readable medium.

A passive radio transmission device is arranged on a front and a back of an electrically conductive carrier plate, wherein the radio transmission device includes, on the front of the carrier plate, a first film having a first antenna and having a microchip coupled to the first antenna and, on the back, a second film having a second antenna, wherein the first film is coupled to the second film via a flexible web, routed around an end face of the carrier plate, that connects the front to the back, so that the second antenna is connected to the first film via at least one connecting line running along the web in order to transmit information from the microchip using both the first antenna and the second antenna, wherein the first film, the second film and the web are combined as one component.

A molded resin product includes a design layer including a decorative layer having a first color, a shielding layer having a second color different from the first color, and a resin base layer. A cover layer formed of a polymer film is disposed close to one end of the design layer. Part of the decorative layer exposed from the shielding layer serves as an exposed region. The exposed region and part of the shielding layer constitute a pattern portion presenting a predetermined figure or character when viewed in plan through the cover layer. The rest of the shielding layer constitutes a base portion. The layer thickness of the base portion is set smaller than the layer thickness of the pattern portion in a region thereof where the shielding layer is formed.

A key-shape data management system includes a storage server, an acceptance server, and a transmission server. The storage server stores vehicle identification information capable of identifying a vehicle, mechanical lock identification information capable of identifying a mechanical lock mounted on the vehicle, key-shape data of a mechanical key used in combination with the mechanical lock, and information on multiple manufacturing bases capable of manufacturing the mechanical key. The acceptance server accepts a request for acquiring the mechanical key together with determining information and delivery location information indicating a delivery location of the mechanical key. The transmission server determines the vehicle identification information based on the determining information, determines the key-shape data based on the vehicle identification information, determines one of the manufacturing bases corresponding to the delivery location, and transmits the delivery location information and the key-shape data to the determined manufacturing base.
