Patent EP-0886943-A2 (EP)
Inventor: GURUSAMI ARAVANAN
IPC: H04L27/233
Filed: 1997-12-04
Abstract: An improved method for signal demodulation, based upon the assessment of an error statistic which is independent of the content of the data stream. To determine the appropriate sampling point within a data period, multiple sampling points are utilized to generate a set of alternative decodings of the data stream. Associated with each of these alternative sets is an error statistic which is computed based upon a known characteristic of the transmitted stream. For example, in Differential QPSK, the encoded phase change is known to be a multiple of 90 degrees. The error statistic would be a function of the difference between each sampled phase and the nearest multiple of 90 degrees. This error statistic provides a quantifiable measure of quality and noise margin associated with each sampling point. The decoded stream associated with the error statistic of highest quality is then selected as the proper decoding of the transmitted data stream. This invention is particularly well suited for processing small data packets, such as ATM.

Abstract: The present invention provides a jitter detector 40
suitable for measuring the jitter in output signals of a PLL
circuit 30 and a semiconductor integrated circuit 50
including the PLL circuit 30 and the jitter detector 40.
The jitter detector 40 detects whether the amount of jitter

signals) is smaller than the predetermined acceptable value
in the products test. The jitter detector comprises a delay
circuit (41 or 42) receiving the first signal (101 or 105)
and delaying the first signal corresponding with the
predetermined acceptable value to generate a first delayed
signal (106 or 107), and a latch circuit (43 or 44) latching
a level of the first delayed signal corresponding with a
rising edge of the second input signal (105 or 101) to
generate a detect signal (108 or 109). The detect signal

Abstract: A loose source routing method is provided to transfer an IP packet
from a transmission source gateway to a transfer destination gateway by
way of ATM nodes, which are freely designated. At the transmission
source gateway, the IP packet given from a user LAN is dissolved into ATM
cells containing a BOM cell whose destination address designates the
transfer destination gateway. In addition, at least one pseudo BOM cell
whose destination address designates an ATM node in the ATM network is
added and is located at a top place of a cell stream constructed by the
dissolved ATM cells. Thus, the cell stream is transferred from the
transmission source gateway to the designated ATM node in accordance
with the destination address of the pseudo BOM cell. The designated ATM
node discards the pseudo BOM cell so that the original BOM cell is now
located at the top place of the cell stream. Then, the cell stream is
transferred from the ATM node to the transfer destination gateway in
accordance with the destination address of the BOM cell. The transfer
destination gateway assembles the ATM cells into the IP packet, which is
then sent to a user LAN.

Les postes, qui sont des dispositifs de communication informatiques, communiquent par des transmissions de messages sur un canal de communications, le contenu des messages de certaines de ces transmissions étant détruit par collision avec des messages envoyés par d'autres postes. Pour résoudre des collisions de transmissions de messages, des intervalles de temps de transmission non chevauchants de durées variables sont produits, et groupés en grappes présentant divers nombres d'intervalles de temps et diverses distances de temps entre ceux-ci. Des séquences de grappes sont formées, dans lesquelles tout poste émettant dans une grappe particulière connaît l'état de ses transmissions de messages avant le début de la prochaine grappe.

Abstract: An optical amplifier for use with a solid state laser which includes a
pair of elongated slabs of a solid state lasing material, such as a rare earth doped
yttrium-aluminum-garnet (YAG) crystal. Two embodiments of the invention are
disclosed. In both embodiments of the invention, each of the elongated slabs is
formed with a square or generally rectangular cross-section. The slabs are
configured such that the longitudinal axes of the slabs are generally co-axial
aligned and the slabs are orientated such that the major axis of the slabs are
generally orthogonal. By configuring the two slabs to be orthogonal with respect
to one another, the integrated thermal lens becomes azimuthally symmetric and
can be compensated by a simple external lens. In addition, the negative lensing
affect along the major axis of one slab is used to compensate for the positive
lensing affect along the minor axis of the other slab and vice versa, thus
minimizing the affects of the astigmatism. In an alternate embodiment of the
invention, a dove prism is used to rotate the beam instead of rotation of the
slabs.

assembly. The piston assembly is formed from two disks (16,18) which are
spaced apart by a spacer (20) with includes radially and longitudinally
oriented planar projections (22,24) which extend to a position radially
inward of a periphery of the disks. The distal ends (26,28) of the
projections form longitudinally oriented surfaces upon which a
toroidal seal (34) slidably rides. At least one of the longitudinally
oriented surfaces includes an air communication groove (36) in
communication with a groove (38) on the trailing disk which extends to
the periphery of the trailing disk. When the piston assembly is
retracted from the housing assembly, the seal engages the leading
disk thereby inhibiting air from flowing through the air
communication groove thereby effectuating damping. However, when
the piston assembly is inserted into the housing assembly, the seal
engages the trailing disk thereby allowing air to flow through the
air communication groove thereby eliminating or minimizing damping.
The cap of the housing is formed by portions of elastic O-rings
which extend across the mouth of the housing slidably retaining the
piston shaft.
