The chromaticity coordinates of colourmetric reference elements are plotted on a CIE diagram to identify reference wavelengths. The ratio of reflected energy from an object at these two wavelengths may then be used to identify a particular colourmetric reference element. The procedure may be automated by electronic equipment A color which is already known approximately may be defined precisely by ...

A resonant tag circuit having at least one resonant frequency is operative in an electronic security system in which the tag circuit is sensed and electronically deactivated to destroy the resonant characteristics of the tag circuit at the detection frequency. The tag circuit is electronically deactivated by a breakdown mechanism operative within the resonant structure of the tag to cause vaporiza...

An electronic surveillance system marker comprises an active component responsive to incident magnetic energy for causing an associated article surveillance system to render an output alarm and deactivatable, through change in the molecular organization of the active component, without requirement for disruption of the unitary character of the component or change in its chemical composition. The m...

The invention concerns a device for using a parallel structure (S) designed for positioning and displacing a mobile member (100) comprising at least a fixed element, at least a mobile member (100) and at least three actuators (200) each including a fixed part (210) and a mobile part (220), the mobile member (100) consisting of a support-sheath (110) of a tool spindle (111). Said device is characte...

The invention concerns a method for making an electronic device, such as a chip card, comprising at least an integrated circuit chip (200) housed in a card body (100) cavity (120). The chip (200) is connected, via strip conductors (112), to interface elements (110). The cavity (120) has sloping walls. The strip conductors (112) and the interface elements (110) form a pattern which results from thr...

An electronic module or label which is adapted to be rendered adhesive including a support film having an insulative film and at a communication interface disposed on the insulative film, at least one microcircuit, the communication interface being connected to the microcircuit by connections, an adhesive tape including an activatable adhesive adhered to the insulative film and a perforation coinc...

The process is for pneumatically projecting by a wet stream a dry composition comprising inorganic particles and a binder in order to form a protective coating (20) on a wall (13) comprises several stages. The composition is transported in a supple pipe (8), wetted and then projected onto the wall. The dry composition utilised comprises a binder easily soluble in water. The dry composition is f...

This invention relates to a spinal implant for promoting fusion of adjacent vertebrae and restoration of normal disc height. The spinal implant includes an upper and lower surface adapted to engage cancellous bone tissue in the vertebral bodies. The spinal implant also includes at least two opposing bearing surfaces adapted to bear against cortical bone tissue in the endplates of adjacent vertebra...

An accelerating admixture for use with spraying cementitious compositions such as shotcrete comprises (a) a compound selected from aluminium hydroxide, aluminium hydroxysulphate and mixtures thereof, and (b) an acidic substance which essentially does not react with the compound. The preferred acid substances are organic acids.

The emulator is a computer with a random access memory (3) and a first (10) and second (11) processor connected to memory by a system bus. To emulate a physical component the emulator has two sets of physical resources seen as distinct by the system bus. The first resource simulates the machine incorporating the component, and the second simulates the physical component.;
