Abstract: The object of the present invention is to provide a full-mesh optical wavelength division multiplexing transmission network device which is capable of exhibiting excellent communication quality and being mass produced, by reducing the accumulation number of coherent crosstalk lights, without any modification of constituent components constituting the conventional one. In the full-mesh optical wavelength division multiplexing transmission network device, provided is an N × N wavelength multi/demultiplexer having a periodic wavelength demultiplexing property in input/output combination, which performs input/output from/to first and second I/O port groups for optical signals and allows lightwaves traveling in opposite directions not to interfere with each other within the circuit, thus reducing the accumulation number of coherent crosstalk lights in WDM wavelength lights and improving S/N of a received light. Particularly, by preventing the accumulation of adjacent crosstalk lights, communications with higher quality can be achieved.

Abstract: Apparatus and method are provided for the distribution of very high quality audio or visual programming material from one or more central hubs (102) to one or more presentation locations (56, 104) such as theaters using high data rate links such as satellites (106). At the central hub (102), a source generation system (108) generates an electronic program signal from an analog signal, a compression/encryption system (110) codes and digitally encrypts the electronic signal, and a modulation/transmission system (114) processes the signal for transmission via the satellite (106). A network management system (112) at the central hub (102) controls the operation of the hub. At the theater (56) or other location, a receiver/demodulator (120) receives the programming signal transmitted using the satellite (106). A theater management system (122) then controls the storage, routing, decoding, and display of the received programming material. Storage arrays (124A-124N) in the theater system (104A-104N) provide for centralized storage of the programming material. The programming material is routed through a local area network to designated auditoriums, several of which may operate within a theater system (104A-104N). At each auditorium, the programming material is decompressed and decrypted for display using electronic projection equipment (132A) and standard auditorium sound systems (134A).

Abstract: The invention provides chimeric molecules that are catalytic antagonists of a target molecule. The catalytic antagonists of this invention preferably comprise a targeting moiety attached to an enzyme that degrades the molecule specifically bound by the targeting moiety. The catalytic antagonists of this invention thus bind to a target recognized by the targeting moiety (e.g., a receptor) the enzyme component of the chimera then degrades all or part of the target. This typically results in a reduction or loss of activity of the target and release of the chimeric molecule. The chimeric molecule is then free to attack and degrade another target molecule.
