A highly secure optical key access control system utilizing unique optical refraction properties of non-duplicatable transparent objects to secure premises or computer databases is disclosed. The said access control system includes an optical key containing an optical element with unique refraction properties and an access module comprising a light source, an image catching array and an electronic processor. The optical element of the optical key is inserted into the access module between the light source and the image catching array at the initial and then several following prearranged positions and a resulting set of unique refraction images appearing on the surface of the image catching array is processed with the electronic processor for comparison against preauthorized sets of refraction images to grant or deny access to the protected premises or protected computer databases.

Highly secure optical key access control system utilizing unique optical refraction properties of non-duplicated transparent objects to secure premises or computer databases is disclosed.

Said access control system includes optical key containing an optical element with unique refraction properties and unique access module comprising source of light, image capture array and electronic processor. An optical element of optical key is inserted to access module between light source and image catching array at initial and then several following prearranged positions and resulting set of unique refraction image appeared at surface of image catching array processed with electronic processor for comparison against the existing database of preauthorized refraction images in database. If resulting set of unique refraction image match with some set of preauthorized refraction images the access to premises or computer databases is permitted.

A lock assembly for use in a vehicle includes a key having a key head and a key shaft. The key shaft defines a recess. A lock cylinder defines a slot and a channel. The slot is in communication with a first end of the channel. A switch door is positioned to cover the slot. A light source is positioned at a second end of the channel. The light source is positioned to illuminate through the channel. A sensor is configured to detect the key. The sensor is coupled with the light source. The sensor is configured to actuate the light source based on a location of the key. A luminescent structure is positioned on the key shaft within the recess.

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 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.
