  • Patent number: 9325488
    Abstract: An interpolator or decimator includes an elastic storage element in the signal path between first and second clock domains. The elastic element may, for example, be a FIFO which advantageously allows short term variation in sample clocks to be absorbed. A feedback mechanism controls a delta-sigma modulated modulo-N counter based sample clock generator. The elastic element combined with a delta-sigma modulator and counter creates a noise-shaped frequency lock loop without additional components, resulting in a much simplified interpolator and decimator.

    Abstract: A wireless device belongs to a wireless communication system and exchanges information within at least one band of frequencies. A method includes detecting a presence of at least one victim device operating within the at least one band of frequencies. The first wireless device is provided with an antenna array, and the detecting step includes analyzing an environment of the wireless device through the antenna array, and if the at least one victim device is detected, reducing interference by controlling the antenna array to steer the antenna beam toward an area located outside a vicinity of the potential victim device to exchanging information within the at least one band of frequencies with at least a second wireless device located in the area.

  • Patent number: 8745407
    Abstract: A virtual machine or hardware processor for an IC-card portable electronic device includes a non-volatile memory unit, a remote decryption unit, and associated objects for storing an executable program in an encrypted format in the non-volatile memory. The IC-card stores a licence key to encrypt and decrypt the executable program through an IC-card interface. The IC-card interface extracts and encrypts the operands of the plain executable program into encrypted operands so as to not limit performance. The remote decryption unit detects if an instruction contains encrypted operands, and queries a decryption to the IC-card interface. The IC-card interface decrypts the encrypted operands and re-encrypts the just decrypted operands into obscured operands through a dynamic obscuration key.

  • Publication number: 20130328113
    Abstract: A rectifier building block has four electrodes: source, drain, gate and probe. The main current flows between the source and drain electrodes. The gate voltage controls the conductivity of a narrow channel under a MOS gate and can switch the RBB between OFF and ON states. Used in pairs, the RBB can be configured as a three terminal half-bridge rectifier which exhibits better than ideal diode performance, similar to synchronous rectifiers but without the need for control circuits. N-type and P-type pairs can be configured as a full bridge rectifier. Other combinations are possible to create a variety of devices.

  • Patent number: 8598620
    Abstract: A modified MOSFET structure comprises an integrated field effect rectifier connected between the source and drain of the MOSFET to shunt current during switching of the MOSFET. The integrated FER provides faster switching of the MOSFET due to the absence of injected carriers during switching while also decreasing the level of EMI relative to discrete solutions. The integrated structure of the MOSFET and FER can be fabricated using N-, multi-epitaxial and supertrench technologies, including 0.25 ?m technology. Self-aligned processing can be used.

  • Patent number: 8581679
    Abstract: Switches that are actuated through exposure to a magnetic field are described. A mobile element of a switch includes one or more anchoring members that are in electrical contact with one of the conductive portions. The mobile element also has a beam that is attached to the one or more anchoring members. The beam can be attached to the one or more anchoring members by flexures. The beam has an end portion that is configured to move toward the other conductive portion when exposed to an external force, such as a magnetic field. Various configurations of anchoring members may significantly decrease initial upward beam deformation upon manufacture of the mobile element, resulting in an increased sensitivity upon exposure to a magnetic field. Methods for manufacturing switches that exhibit increased sensitivity to magnetic fields are also disclosed.
