    Abstract: A multi-channel rotary joint, designed to couple a stationary and a rotary component of a radar system to each other, comprises a main channel centered on the axis of rotation and a plurality of axially spaced ancillary channels coaxially surrounding the main channel. Each ancillary channel is formed by two capacitively coupled coplanar rings respectively carried on a stationary and on a rotatable dielectric sleeve centered on the axis, each ring comprising two concentric annular conductor strips on the inner and the outer sleeve surface. The inner and outer conductor strips of each ring are interrupted by small equispaced gaps which are relatively offset to form overlapping segments of two concentric transmission lines which are electrically continuous except at one point at which the line is coupled to a respective balun also formed by arcuate conductor strips.

    Abstract: A lead with an increased impedance for an active implantable medical device, in particular for a pacemaker. The lead comprises a cylindrical body (14) presenting at its distal end a contact surface (30) for making contact with the endocardium, which is electrically insulated, and a stimulation electrode (16), which is electrically conducting and which is connected to a conductor of the lead. The electrode (16) has at least one active element (22), for example, a plurality of protuberances (22), each one presenting at least an exposed extremity tip (26) having a hemispherical area, making a ledge compared to the contact surface (i.e., protruding) therefrom. The active element presents on at least a part of its exposed extremity to be placed in contact with the endocardium a radius of curvature less than 0.5 mm, more preferably less than or equal to 0.3 mm. With a microporous vitreous carbon as the material of the protuberances, one can at least increase the contact impedance of the lead at the heart/electrode interface to 800 Ohm, preferably up to approximately 1000 Ohm. An annular flat form or disc-shaped active element also can be used as an alternative to the protuberance(s).

    Abstract: A circuit and method for controlling the speed of a universal motor driven by an AC source is disclosed. The method includes the steps of measuring a value of a temporal property of a current through the motor and determining a speed of rotation of the universal motor using the temporal property. The method for controlling the speed of the universal motor further includes comparing the determined speed of rotation with a desired speed of rotation and adjusting the current through the motor so that the speed of the motor approaches the desired speed of rotation.
