Abstract: A lead system has an elongate body, an active fixation assembly movable relative to the elongate lead body, including a non-stationary electrode. The lead system further includes a non-stationary electrode member and an electrical interconnect electrically connected between the non-stationary electrode member and the stationary electrode member. The electrical interconnect provides a reliable electrical interconnection between the stationary electrode and the non-stationary electrode, while allowing the non-stationary electrode to move relative to the stationary electrode.

Abstract: A lead system has an elongate body, an active fixation assembly movable relative to the elongate lead body, and a low variation friction member frictionally engaged with the active fixation assembly. In an option, the active fixation assembly undergoes greater torsional resistance as the active fixation assembly is moved in a direction to retract the lead.

Abstract: A direct conversion satellite tuner is fully integrated on a common substrate. The integrated tuner receives an RF signal having a plurality of channels and down-converts a selected channel directly to baseband for further processing. The integrated tuner includes on-chip local oscillator generation, tunable baseband filters, and DC Offset cancellation. The integrated tuner can be implemented in a completely differential I/Q configuration for improved electrical performance. The entire direct conversion satellite tuner can be fabricated on a single semiconductor substrate using standard CMOS processing, with minimal off-chip components. The tuner configuration described herein is not limited to processing TV signals, and can be utilized to down-convert other RF signals to an IF frequency or baseband.

Abstract: A composition for retaining dentures in the mouth of a denture wearer including 5-8% w/w of an hydrophilic gelling agent, 2-7% w/w of a thickening agent, 5-20% w/w of ail agent that imparts water resistance to the composition, 0.2-5% w/w of humectant(s) and the balance being water, the composition being formable into a viscous hydrophobic film in use. A method of retaining dentures in the mouth of a denture wearer by applying to the denture or the mouth tissue the composition and placing the denture into position in the mouth in a manner such that the composition substantially forms a seal between the mouth tissue and the denture to thereby assist in the retention of the denture.
