    Abstract: AC/DC converters comprise rectifiers for rectifying AC signals into DC signals. By providing these AC/DC converters with voltage dividing capacitors located between converter-input, a resistor, added to voltage dividing capacitor for filtering peak signals, and a rectifier, the rectifier can be better integrated, as it no longer receives the entire input voltage present at the converter-input of the AC/DC converter, without a conventional transformer comprising an iron core and windings being required. Such an AC/DC-converter is small sized, of light-weight and low costly made. Preferably, the converter-input is symmetric, the rectifier comprises two diodes and two transistors and a zero-cross detector for switching the transistors, the AC/DC converter comprises a down-converter located between the rectifier and converter-output for further down-converting purposes and comprising an inductor and a regulator for regulating inductor/capacitor-energies, with buffer capacitors being present in parallel to the down-converter for stabilising purposes, to get a transformerless wall plug adapter.

    Abstract: An incident pulse signal of the ultra wideband type conveys digital information that is coded using pulses having a known theoretical shape. A decoding device includes an input for receiving the incident signal, and for delivering a base signal. A comparator receives the base signal and delivers an intermediate signal representative of the sign of the base signal with respect to a reference. A sampling circuit samples the intermediate signal for delivering a digital signal. A digital processing circuit correlates the digital signal with a reference correlation signal corresponding to a theoretical base signal arising from the reception of a theoretical pulse having the known theoretical shape.

    Abstract: The invention is a servo compensation method and system for use in a disk storage system. The disk storage system experiences error that causes a head to become mis-aligned with the disk. The error comprises run-out error and other servo position errors. During follow mode, a digital filter processes a position error signal to generate a compensation signal. The position error signal is comprised of components representative of the run-out error and the other servo position errors. The compensation signal is comprised of components that cause the servo positioning system to compensate for the run-out error and the other servo position errors. The digital filter also operates as an oscillator that provides an oscillating signal the spin frequency of the disk during seek mode.

    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.

    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 μm technology. Self-aligned processing can be used.
