Patent EP-1195926-A1 (EP)
Inventor: PRESBY HERMAN MELVIN
IPC: H04B10/118
Filed: 2001-04-17
Abstract: A free space optical communication system is disclosed whereby the
received power at the receive optical fiber is reduced by adjusting the
transmitted light beam and the receive optical fiber with respect to each other
when a specified power threshold is exceeded so that they intersect not at a
point of focus, but at a point of divergence of the transmitted beam. In one
embodiment, the transmitted beam may be diverged by moving the transmit
optical fiber to a point in front of the focal plane of the transmit telescope
along the longitudinal axis of that telescope until at least a portion of the
beam is incident upon the receive optical fiber. This causes the transmitted
beam to diverge and, accordingly, the cross-sectional area to increase at the
point where it is incident upon the receive telescope. As a result, the cross-sectional
power per unit area of the transmitted beam at the receive
telescope is reduced which correspondingly reduces the power that is
incident upon the receive optical fiber. 
     In another embodiment, instead of moving the optical fiber at the
transmit telescope, the optical fiber located at the focal plane of the receive
telescope may be moved to either a point in front of or to a point to the rear
of the focal plane of the receive telescope along the longitudinal axis of the
receive telescope. Since the maximum possible received power is achieved
at the focal point within the focal plane, any movement of the receive optical
fiber away from the focal point along the longitudinal axis of the receive
telescope will result in a reduction of the received power.

Abstract: A steel blade for turbomachinery, for example a vane or blade of stainless steel for a steam turbine, has its working surface smoothed, for example by tumble polishing, to a smoothness of about 0.25 microns Ra or less. Then the smoothed surface is subjected to plasma nitriding to harden the surface to a value of, for example, about 1000 on the Vickers hardness scale. The hardened nitrided layer in the steel can be 25 to 100 microns thick. The plasma nitriding process does not affect the smoothness of the area of surface being nitrided, and the resultant surface hardness preserves smoothness of the surface while the blade is in use.

Abstract: A  "Burst Ratio"  is defined for use as a measure of the burstiness of a packet-based
network. One illustrative implementation of the  Burst Ratio  ( R ) is where  R  is
equal to the ratio of the average length of observed bursts in a packet arrival sequence
over the average length of bursts expected for a random loss packet-based network.
Another illustrative implementation of the  Burst Ratio  ( R ) is in the context of a 2-state
Markov model, wherein  R  =  1  /  (1 + α - β), and α is the probability of losing packet  n 
if packet  n-1  was found (i.e., the probability of losing the next packet if the current
packet was received) and β represents the probability of losing packet  n  if packet  n-1 
was lost (i.e., the probability of losing the next packet if the current packet was lost).

Abstract: A noncontact physical property measurement instrument which
easily and accurately measures physical properties of an object
using a nondestructive, noncontact sensor. A noncontact physical
property measurement instrument 1 is provided with a transmitting
section 21 and a receiving section 22. The transmitting section
21 sends a wave to an object 41 in a medium 100, and the receiving
section 22 receives a wave reflected from the object 41 and the
surface of a coating 42. Both the transmitting section 21 and the
receiving section 22 are connected to a gain change correction circuit
13 to form a self-excited oscillating circuit 11 serving as a feedback
loop. The gain change correction circuit 13 corrects the gain to
the increase side according to a phase difference between the sent
wave and the reflected wave, to thereby measure any changes due
to a difference in physical properties of the object 41.

Abstract: The invention relates to an apparatus for reading out information from an information carrier, the information including at least a first signal of at least partly encrypted content, to an apparatus for storing such information as well as to corresponding methods. The invention proposes a realisation of the Content Scrambling System (CSS) rule: CSS encrypted content on a recordable disc should be refused. In order to be able to use a wobbled disc for distinguishing ROM-discs from recordable discs, it is required that in the content on "new" discs there will be a "wobble-trigger". This trigger has the following requirements: -it should be easily detectable from looking just at the content, -it should not be easily removable by a hacker, -it should not affect content preparation. It is thus proposed according to the invention that an apparatus for reading out information comprises: means for detecting a second signal logically embedded in the first signal, means for detecting a physical mark used for storing at least part of the information on the information carrier, and means for refusing play back of the information read from the information carrier if a second signal but no physical mark has been detected.
