Patent EP-0496603-A1 (EP)
Inventor: GRUBB STEPHEN GREGORY
IPC: H01S3/094
Filed: 1992-01-22
Abstract: An optical amplifier is provided that includes an optical fiber for amplifying a light signal in a single transverse mode. The amplifier provides high gain at high levels of output power for wavelengths in the 1.535 micron region. The fiber has an inner core and an outer cladding end pumped by a Nd laser rod, where the inner core] comprises a host glass doped with erbium (Er) and a sensitizer such as ytterbium (Yb) or iron (Fe). Preferably the host glass is phosphatic glass, but it may also be doped silicic glass (e.g., phosphate or borate doped). Electrical energy is provided to diode lasers that pump the Nd laser rod, which in turn pumps the fiber. Such a configuration for pumping the fiber provides a high energy transfer from the diodes to the Nd laser rod, which in turn enables high pumping powers to be coupled into the single-mode co-doped fiber. Based on the amplification characteristics of the co-doped fiber and the efficient coupling of power from the laser diodes, the amplifier provides power and small signal gains comparable to the best observed, while requiring only conventional and readily available diode-based pump sources.

Abstract: A device for checking the in-register positioning of a printing plate on the plate cylinder (1) of printing machines has, in the tension rail (3, 4) for receiving this printing plate, measuring sensors, by means of which the in-register position can be detected in the form of electrically interrogatable signals. So that these signals can be interrogated directly by machine control, for example in conjunction with an automatic or manual printing-plate feed, contact faces are mounted in the region of the tension rail. These contact faces are assigned sensing heads (29, 30) which are mounted on the frame movably relative to the plate cylinder and which can be pressed against these very contact faces after a corresponding angular positioning of the plate cylinder. During the introduction of a new printing plate, therefore, an evaluation unit for receiving the signals is connected to the measuring sensors. <IMAGE>

The internal data traits include an identification code. The plurality of wireless subscriber units also receive a transmitter/receiver signal. A receiver/transmitter is located remote from the wireless subscriber units and receives the wireless subscriber signal and transmits the transmitter/receiver signal. A characterizing device is connected to the receiver/transmitter and generates a plurality of characterizing signals for one of said wireless subscriber units. The characterizing device generates said plurality of characterizing signals by measuring features of said external traits of said one said wireless subscriber signal from at least one of a first category including variations of specified parameters of said one of said wireless subscriber units, a second category including variations in non-specified parameters, and a third category including variations in reactions or responses to interrogations. A converter connected to the characterizing device converts the plurality of characterizing signals into a security pattern. The security pattern and the identification code are used to identify said one of said wireless subscriber units. A historic security pattern storing device stores historic security patterns for said wireless subscriber units. A comparing device connected to the converter and the historic security pattern storing device compares the security pattern to the historic security pattern corresponding to said one of said wireless subscribers and generates a confidence level indicating a likelihood that one of said wireless subscriber units also generated the historic security pattern. An access device grants or denies access to the subscriber service based upon the confidence level.
