  • Publication number: 20120066702
    Abstract: An apparatus for storing digital media utilizes an electrically conductive element, which is for reading stored digital media, and multiple electrically conductive resonant circuits as an antenna for radio frequency communications. Each of the resonant circuits is electrically isolated from the other resonant circuits and the electrically conductive element is electrically isolated from each of the resonant circuits. As a result, the apparatus for storing digital media has a relatively wide operating frequency range and a relatively long communications range, which allows worldwide usage in various applications. For example, an optically readable compact disk (CD) utilizes a metal layer configured as a reflective surface for reading stored digital media in the CD, an electrically conductive component that is not in contact with a radio frequency identification (RFID) integrated circuit (IC), and an electrically conductive component that is in contact with the RFID IC, as an antenna for the RFID IC.

  • Publication number: 20120062031
    Abstract: A multi-output DC to DC converter can have complex control requirements in CCM mode because of the differing load requirements of the outputs. A multi-output DC to DC converter having a single coil or inductor and a freewheel switch is described. A controller measures the duration of the freewheel phase. The controller increases the current supplied to the DC to DC converter in the following duty-cycle if the duration is less than a first value, and decreases the current supplied to the inductor in the following duty-cycle if the duration is greater than a second value.

  • Patent number: 8133791
    Abstract: The invention relates to a method according to the part of the surface of the semiconductor body adjoining the opening and which is to be kept free is provided with a cover layer after which the high-crystalline layer is formed by means of a deposition process. The material of the cover layer can then easily be chosen such that it can be selectively etched relative to the silicon underneath. In addition, the cover layer can easily be selectively deposited on the relevant part of the surface because use can be made of an anisotropic deposition process. In such a process the cover layer is not deposited in the hollow and on the bottom of the hollow. It will be apparent that for the high-crystalline layer also other materials can be chosen such as SiGe having such low Ge contents that the SiGe cannot be etched selectively very well compared to the Silicon.

  • Patent number: 8134142
    Abstract: The invention suggests a transistor (21) comprising a source (24) and a drain (29) as well as a barrier region (27) located between the source and the drain. The barrier region is separated from the source and the drain by intrinsic or lowly doped regions (26, 28) of a semiconductor material. Potential barriers are formed at the interfaces of the barrier region and the intrinsic or lowly doped regions. A gate electrode (32) is provided in the vicinity of the potential barriers such that the effective height and/or width of the potential barriers can be modulated by applying an appropriate voltage to the gate electrode.

  • Patent number: 8134603
    Abstract: The present invention relates to a method and system for a digital image stabilization intended to remove unwanted camera movement or jitter, both translational and rotational jitter. The system comprises the following means: 1) a motion estimation stage (10) of the global motion of the camera: block motion vectors are calculated for specific parts of the image and global motion parameters representing the camera motion are then derived. 2) a motion/jitter filtering stage (11): the translation vector and the rotation angle are filtered separately, a boundary check being then performed for verifying if the correction thus done is not above an allowed threshold. 3) a jitter compensation stage (12): the raw sequence is compensated according to the extracted jitter and the result is a stabilized sequence.

  • Patent number: 8135375
    Abstract: A gain-controllable stage (CLN, A1, A2 . . . , A7, ACC) comprises a reactive signal divider (CLN) followed by an amplifier arrangement (A1, A2 . . . , A7, ACC). The reactive signal divider (CLN) may be in the form of, for example, a capacitive ladder network. The gain-controllable stage (CLN, A1, A2 . . . , A7, ACC) has a gain factor that depends on a signal division factor that the reactive signal divider (CLN) provides. The reactive signal divider (CLN) forms part of a filter (LC). The signal division factor is adjusted on the basis of a frequency (F) to which the receiver is tuned and a signal-strength indication (RS).

  • Publication number: 20120055768
    Abstract: A MEMS electrostatic actuator comprises first and second opposing electrode arrangements, wherein at least one of the electrode arrangements is movable. A dielectric material (24) is adjacent the one of the electrode arrangements (22). The second electrode arrangement is patterned such that it includes electrode areas (26) and spaces adjacent the electrode areas, wherein the dielectric material (24) extends at least partially in or over the spaces. The invention uses a multitude of electrode portions as one plate. The electric field lines thus form clusters between the individual electrode portions and the opposing electrode. This arrangement provides an extended range of continuous actuation and tunability.

  • Publication number: 20120049937
    Abstract: It is described a high efficiency rectification stage using dynamic threshold MOSFET. The idea is to use the input signal to reduce the threshold voltage when the transistor has to be on, and to increase the threshold when the transistor has to be off. This allows reducing both the resistive losses and the leakage current. A matching network allows the generation of a second higher voltage signal to drive the control gates and the bulk, i.e. the wells, of the transistors. Further, a self-tuned front-end is provided to extend the bandwidth of the high-Q charge pump.
