  • Patent number: 8259460
    Abstract: A submount for arranging electronic components on a substrate is provided. The submount comprises a head member and at least one substrate-engaging member protruding from the head member. The head member comprises at least two, from each other isolated, electrically conductive portions, where each electrically conductive portion comprises a component contact, adapted for connection of electronic components thereto, and a substrate contact on arranged on said substrate side, adapted for bringing said electrically conductive portions in contact with a circuitry comprised in said substrate. The submount of the present invention may be used to attach electronic components, such as light-emitting diodes, to a textile substrate, without the need for soldering the electronic component directly on the substrate.

  • Publication number: 20080221813
    Abstract: An optical disc drive apparatus (1), suitable for storing information on or reading information from an optical disc (2), typically a DVD or a CD or a BD, is designed for performing a method for calibrating a jitter factor (X) on the basis of optimising jitter, the method comprising the steps of: receiving a read signal (SR) from the optical disc (2); detecting a zero-crossing in the read signal; measuring (steps 111, 112) a timing error (t?(i)) of the zero-crossing; measuring (step 113) a steepness (?(i)) of the zero-crossing; calculating (step 114) a weighing factor (?(i)) on the basis of the measured steepness (?(i)), this weighing factor (?(i)) being smaller for smaller values of the steepness (P(O); calculating (step 115) a weighed single jitter value (tw(i) by multiplying said timing error (t?(i)) and said weighing factor (?(i)); and using this weighed single jitter value for calibration.
