Abstract: A coupled multiple output fiber laser includes  a plurality of laser diodes (10, 50-56) each providing pump light (12, 58-64) which is incident on respective Bragg gratings (16, 74-80) which pass   the pump wavelength and reflect a lasing wavelength.  The fibers   (20, 90-96) are doped with a gain dopant such as Er3+ to provide lasing at the lasing wavelength in response to the pump light.  Light beams (18, 82-88) are incident on an  optical coupler (22) which couples the light beams (18, 82-88) to the light beams (40-48) on the fibers (30-38) based on a predetermined power distribution e.g., equal distribution.  The light (40) travels along the fiber (30) which acts as a common-cavity fiber. The light (40) reflects off a reflector (120) which provides reflected feedback light (122) which reenters the coupler (22)  and is  distributed to the individual cavity fibers  (20, 82-88) based on the same or a different predetermined  power distribution.  Output light (42-48) is provided on the fibers (32-38) which may be incident on a lens (160) to cause the beams to intersect.  The length  of each of the fibers (20, 90-96) is adjusted by piezoelectric tuners (200-208) to provide coupled cavity  phase-locking of the output beams (42-48). Also, each of the output beams (42-48) may be phase shifted by additional tuners (240-246).  An additional output beam may be obtained by a light (232) which passes through  the mirror (120).

Title: Channel switched mail message switching and metering system
Inventor: SANSONE RONALD P
IPC: G06Q10/04
Filed: 1997-12-22
Granted: 2001-08-21
Abstract: The invention is a method for channeling message traffic along an optimal path to its intended destination. The method is accomplished by drafting a message and a corresponding destination address together in electronic form. The message and address are coupled with a set of parameters which define a method of conversion of the electronic form of the message and address to a tangible form. The message and address are transmitted together with the conversion parameters, as a packet, to a routing facility via a digital carrier. The routing facility will select an optimal transmission path whereby the packet will be transmitted to the terminal node for conversion and printing. The selection of an optimal path is made by analyzing a set of weighted factors pertaining to a set of possible pathways. The combination of weighted scores will be used to determine which path has the highest weighted score. The path with the highest weighted score will be selected, and the transmission will be initiated by the routing facility along that path. The terminal node comprises receiving means for receiving the packet and printing means for converting the electronic message and address to human readable form by printing the message on a medium and printing the destination address on an envelope, from these a finished mail piece is formed and placed into a local mail stream for delivery to the destination address.

Abstract: A unique time slot is assigned to each of a plurality of wavelengths emitted by a single, centralized wavelength division multiplexed optical source to provide a "bit interleaved" WDM signal. In accordance with an illustrative embodiment of the present invention, the thus-developed bit-interleaved WDM signal is replicated in cascaded stages of amplification and power splitting before data is encoded for respective frequency dependent receivers as, for example, a plurality of passive optical networks. Because the output of the optical source need not be encoded with data for the respective receivers until after many stages of splitting and amplification, a small number of time division multiplexing (TDM) modulators synchronized to the source may be used to deliver data to potentially tens of thousands of subscribers.

Granted: 2006-10-17
Abstract: The present invention is a hydrodynamically lubricated interference type rotary shaft seal suitable for environmental exclusion and high pressure lubricant retention which incorporates an environment-side groove to control and minimize interfacial contact pressure at the dynamic sealing interface, which permits optimum hydrodynamic film thickness, thereb y significantly lowering the self generated heat produced by the seal, as compared to the prior art. The cool-running nature of the present invention permits the use of higher modul us seal materials and higher surface speeds, compared to the prior art, and allows the seal to operate in applications with relatively poor heat dissipation. The controlled interfacial contact pressure of the present invention also permits effective hydrodynamic lubrication with lower viscosi ty lubricants, including water.
