    摘要: An integrated bi-directional MMDS/MDS converter connected to an antenna for receiving MMDS programming for receiving information/data signals from a set top for retransmission of these signals back to central location. The integrated bi-directional converter has a down converter connected to the diplexer for down converting conventional programming signals into a group of converted programming signals in the 222 to 408 MHz range, an up converter for up converting data/information signals in the 116 to 128 MHz range from the communication line into MDS signals and delivers it into the diplexer. The diplexer applies the outgoing MDS data signals to the feed of the antenna for transmission. The integrated bi-directional MMDS/MDS converter of the present invention uses a common local oscillator for driving both the down converter and the up converter.

    摘要: Patch-based devices for enhancing the local delivery of drugs, pharmaceuticals, plasmids, genes and other agents into the tissues of the living body. The patch devices provide an electrical driving force that can increase the rate of migration of drugs and other therapeutic agents out of a polymer matrix into body tissues and cells using iontophoresis only, electroporation only, or combined inontophoresis and electroporation. The two procedures may be applied sequentially in any order without removing or repositioning the patch.

    摘要: The present invention provides a device (10), and methods of use thereof, for the targeted delivery of radiation, in vivo. The therapeutic radiation delivered by the device (10) of the present invention can be used, for example, to prevent restenosis after angioplasty. The catheter device (10) of the present invention is especially suited for such treatment because it substantially aids in the delivery of radiation to an intravascular treatment site. In addition, to delivering radiation emitting materials to an intravascular site, the present invention can also incorporate radiation shielding to increase the safety and accuracy of the delivery of the radiation emitting materials.

    摘要: An apparatus of the present invention is adapted to provide a telephone line connection over a coax cable distribution system. In a home having a plurality of set-top television boxes which each require a connection to a telephone line, the present invention allows a single telephone line connection to be provided to the plurality of set-top boxes via the coax cable distribution system. The invention uses a first interface device connected to a telephone line to modulate telephone signals and transmit them over the coax cable distribution system. The device also includes a demodulator to demodulate signals received over the coax cable distribution system to be sent over the telephone line. The invention includes a second interface device at each set-top box which also includes a modulator and demodulator to transmit and receive telephone signals over the coax cable distribution system.

    摘要: The present moisturizer for air going into a combustion process has a venturi passageway through a liquid permeable, porous, open-ended, annular body surrounded by liquid such as water and a valve in the venturi passageway. The valve is spring-biased toward the air inlet end of the venturi passageway to provide a maximum flow restriction at low volume demand. The valve deflects air outward against the inside wall of the porous body which defines the venturi passageway for the purpose of enhancing the withdrawal of moisture from the porous body, particularly at low volume demands. At progressively higher volume demands, the valve is displaced by the air toward the air outlet end of the venturi passageway to enlarge the effective open area of the passageway around the valve. Preferably, the valve operates to keep the air velocity through the venturi passageway substantially constant at different air flow demands.
