  • Patent number: 7915540
    Abstract: A tamper-proof structure for protecting an electronic module, comprising a pattern of signal lines having a highly unpredictable layout, which is an approximation of a space-filling curve obtained by the replication of at least one elementary space element having an inscribed base curve inscribed therein. The base curve is adapted, by replication of the elementary space element, to generate an approximation of an at least two-dimensional space-filling curve, the replication being such that an end of the base curve in one elementary space element is connected to the end of the base curve in another, adjacent elementary space element of the replication.

  • Patent number: 7902461
    Abstract: A cryogenically-cooled HTS cable is configured to be included within a utility power grid having a maximum fault current that would occur in the absence of the cryogenically-cooled HTS cable. The cryogenically-cooled HTS cable includes a continuous liquid cryogen coolant path for circulating a liquid cryogen. A continuously flexible arrangement of HTS wires has an impedance characteristic that attenuates the maximum fault current by at least 10%. The continuously flexible arrangement of HTS wires is configured to allow the cryogenically-cooled HTS cable to operate, during the occurrence of a maximum fault condition, with a maximum temperature rise within the HTS wires that is low enough to prevent the formation of gas bubbles within the liquid cryogen.

  • Patent number: 7903431
    Abstract: A shielding apparatus is disclosed suitable for use in providing electromagnetic interference shielding for an electrical component on a substrate. The shielding apparatus includes a frame that is at least partially drawn in construction and is configured for installation to the substrate. Side walls of the frame generally surround the electrical component, and a cover is attachable to the frame for substantially covering the electrical component. The cover includes an upper surface having an inverted embossment formed therein, and a cover member extending generally downwardly from the upper surface adjacent the inverted embossment. The inverted embossment and cover member define a guide for guiding and receiving at least part of the frame into the guide when the cover is attached to the frame. The guide is configured to help facilitate and generally hold the cover in electrical contact with the frame when the cover is attached to the frame.

  • Patent number: 7889515
    Abstract: In one exemplary embodiment, an electromagnetic interference (EMI) shielding apparatus generally includes a shield and a gasket. The gasket includes at least one tab formed monolithically with the gasket and attached to a support or portion of the gasket. The at least one tab is movable relative to the support from a first, pre-installed configuration in which the at least one tab is generally co-planar with the support to a second, installed configuration in which the at least one tab extends generally outwardly relative to the support. Movement of the at least one tab from the first configuration to the second configuration may position the at least one tab at least partially within the at least one opening of the shield. Frictional engagement of the at least one tab within the at least one opening may help retain the relative positioning of the gasket to the shield.

  • Patent number: 7876577
    Abstract: A system for connecting electrical devices to one another is provided. This system includes a horizontal or non-horizontal substrate and an anchor connected to or formed integrally with the substrate. The anchor is either a raised structure or a recessed structure, and further includes at least one retention member formed integrally with the anchor. At least one electronic component is mounted within the anchor and the at least one retention member secures the component to the substrate. At least one electrical trace is disposed on the substrate and the at least one electrical trace extends into the anchor, contacts the at least one electronic component, and forms an electrical connection between the substrate and the at least one electronic component.

  • Patent number: 7859856
    Abstract: A protocol analyzer for analyzing traffic on a bus. A tap card is used to tap into a bidirectional bus. The tap provides a pass through connection from the card to the host and taps off of the bus. While tapping off the bus, stubs lengths are minimized and input capacitance is minimized. A repeater that preferably has no internal termination provides a differential input and a differential output or a single ended output. The bus lines are input to one of the inputs in the differential inputs and a reference voltage is provided to the other differential input. The reference voltage enables the tap to determine if the data is high or low. A jumper is also included in the tap such that the reference voltage can be selected from the host or from the pod.

  • Patent number: 7842883
    Abstract: A power line arrangement includes a first power line and a second power line which crosses the first power line at least once. The first and second power lines are connected to a same power supply, and current in the first power line flows in a different direction from current in the second power line at an area where the first and second power lines cross.

  • Patent number: 7839647
    Abstract: An insulating film includes a first polymer layer, a second polymer layer and an electromagnetic shielding layer sandwiched between the first polymer layer and the second polymer layer. The electromagnetic shielding layer includes a number of carbon nanotube films that are substantially parallel to the first and second polymer layer. Each of the carbon nanotube films includes a number of carbon nanotubes that are substantially parallel to each other. The insulating film can provide anti-EMI effect in printed circuit boards without employing additional electromagnetic shielding layers.
