摘要： The present invention relates to the field of enclosures for electronic circuits and in particular to applications, for example payment card systems, where it is necessary to provide some physical security to prevent unauthorised access to a circuit and more particularly to the data contained within memory devices in the circuit. The present invention provides an improved housing overcoming problems associated with prior art housing and in particular provides a housing that allows for replacement and/or repair of an underlying circuit at a relatively low cost. This is achieved by provision of a single piece construction security housing having conductive patterns integrally provided thereon. In particular, a first embodiment of the invention provides a security housing for mounting in use on a circuit board to protect an associated circuit, comprising: a plurality of electrical contacts for making electrical contact with the circuit board, a cover, a plurality of side walls, where the plurality of side walls and cover define a space for accommodating the associated circuit, and at least one pattern of conductive tracks electrically connected to the electrical contacts and integrally formed with the plurality of side walls and the cover in a single piece construction.

摘要： An electronic device is manufactured using printed circuit board manufacturing processes. In particular, a laminar device comprises a first metal layer (12), a second metal layer (14), at least one layer of device material sandwiched between the first and second metal layers. A first layer of insulating material (40) substantially covers the first metal layer (12). A third metal layer (48) is provided on the first layer of insulating material (40). This third metal layer (48) is divided to provide a first terminal (90) and a second terminal (92). The first terminal (90) is electrically connected to the first metal layer (12) by a conductive interconnect (84) formed through said first layer of insulating material (40), and the second terminal (92) is electrically connected to said second metal layer (14) by a conductive path (68) comprising an insulated conductive channel which passes through and is insulated from said first metal layer (12) and said at least one layer of device material (16). The use of an insulated channel provides a cost effective method of manufacture and maximizes the effective area of device material used. A PTC component is built through this method.

摘要： A variable resistive element for use in a sensing unit for measuring liquid level in a container, through interaction with a sliding electrical contact operating in conjunction with a float, includes a conductor pattern deposited on a substrate. A region of resistive material is also deposited on the substrate and makes electrical contact with the conductive pattern. A region of the conductor pattern functions as a contact area for the sliding electrical contact. This region is coated with a plating material, for example nickel or a nickel alloy. The use of the plating reduces the requirements for expensive metals in the conductor pattern. The variable resistive element is particularly suited for use in a fuel level sensor.

The assembly further comprises a shaft having a diameter sized to fit into the central bore, and having a flattened key which is configured to fit into the at least one slot. The rotor and shaft fit into a housing having an inner section sized to receive the drum-like rotor and encoder elements. The inner section has an opening along one side such that the inner section incompletely encloses the circumference of the rotor. There is also at least one spring contact locatable within the housing such that it can make contact with the encoder elements through the opening in the inner section of the housing.

摘要： An encoder to convert absolute angular or linear position to digital information, and a method to derive code sequences to produce such encoders. A sensor-detectable code, such as a binary, ternary or quaternary code, is arranged along a single track (11), and sensors (21, 22, 23, 24) are positioned in a prescribed manner along the track to sense the code. The sensors may be mechanical contacts, optical detectors, magnetic detectors, or capacitive detectors. The sensors (21, 22, 23, 24) and the information elements (12, 13, 14) of the code are arranged such that the digital output sequence produced by the sensors (as the track is moved relative to the sensors) is Gray-encoded, and such that a high level of code efficiency is obtained. Codes sequences are derived using a method which involves the generation and ordering of necklaces.
