  • Reception of modulated carriers having asymmetrical sidebands
    Patent number: 6324233
    Abstract: In a receiver for receiving a modulated carrier (MC) having asymmetrical sidebands (USB,LSB), for example, a TV signal, a synchronous demodulator (SDEM) derives a vectorial baseband signal (VB) from the modulated carrier (MC). A filter (FILT) filters the vectorial baseband signal so as to compensate for the sideband asymmetry, for example, by means of a Nyquist slope. Thus, the sideband asymmetry is compensated at baseband frequencies, rather than at an intermediate frequency, which allows a better quality of reception.

  • Osmotic-delivery devices having vapor-permeable coatings
    Patent number: 5798119
    Abstract: An osmotic device that, following the imbibition water vapor, provides for the controlled release of a beneficial agent to a non-aqueous environment. The device comprises a hydrophilic formulation and a beneficial agent, surrounded by a wall. The wall is formed at least in part of a semipermeable hydrophobic microporous membrane having an average pores size between about 0.1 .mu.m and 30 .mu.m. The pores are substantially filled with a gas phase. The hydrophobic membrane is permeable to water in the vapor phase and the hydrophobic membrane is impermeable to an aqueous medium at a pressure less than about 100 Pa. The beneficial agent is released, for example, by osmotic pumping or osmotic bursting upon imbibition of sufficient water vapor into the hydrophilic formulation. The high water fluxes attendant with these vapor-permeable hydrophobic membranes facilitate the delivery of large quantities of beneficial agents without requiring large surface areas (quantities) of hydrophobic microporous membrane.

The look-ahead detection system utilizes downward-looking sensors to help the system predict when the craft will strike the water and how strong the impact will be. That is, the look-ahead detection system uses the sensors to look forward in time and down in space.
