Title: Optical waveform for use in a dwdm optical network and systems for generating and processing same
Inventor: HARLEY JAMES
IPC: H04L5/02
Filed: 2001-03-06
Granted: 2014-10-07
Abstract: An optical signal occupying one or more wavelengths. An optical data signal on each wavelength is modulated with a respective overhead (dither) signal, resulting in a respective dithered optical signal. The amplitude of a particular overhead signal used to modulate the corresponding optical data signal is chosen so that the RMS value of the overhead signal in the dithered optical signal is proportional to the average intensity of the optical data signal. The instantaneous frequency of each overhead signal is time-varying and each possible frequency belongs to a distinct set of frequencies which are all harmonically related to a fundamental frequency. The distinctness of each set of frequencies allows each overhead signal to be uniquely isolated from an aggregate overhead signal. The harmonic relationship among the frequencies allows improved accuracy of RMS detection at a receiver as well as reduced computational complexity, as each possible frequency for each overhead signal can be made to fall at the center of one of the frequency bins of a single FFT of reasonable size performed at a receiver. Methods and systems for generating and detecting such signals are disclosed.

Abstract: An oxidation-resistant alloy for use in a high-temperature or thermal cycling environment. The alloy comprises a nickel-based matrix having a solid solution of 19-23 % chromium and 3-6 % aluminum. A self-healing, thermodynamically stable oxide layer is formed upon a surface of the alloy which is exposed to an oxidizing atmosphere over a range of temperatures for extended periods of time. The oxide layer protects the alloy from the oxidizing atmosphere. Additions of calcium and yttrium are made to the matrix to substantially remove or stabilize oxygen and sulfur dissolved in the molten alloy. These additions result in retention of about 0.005-0.05 % of calcium and 0.01-0.06 % yttrium in the cast alloy. The matrix further includes about 2-8 % iron to inhibit nucleation and growth of a "gamma prime" nickel aluminum intermetallic compound which would otherwise adversely harden the alloy and cause local disturbance of a uniform distribution of aluminum. The alloy has a VHN below about 350.

Title: Method and apparatus for detecting forward and reverse link imbalance in digital cellular communication systems
Inventor: SOLIMAN SAMIR S
IPC: H04B7/26
Filed: 1999-10-05
Granted: 2009-11-03
Abstract: A method and apparatus for detecting forward and reverse link imbalances in a digital cellular communication system. The method preferably uses an indication of "maximum access probes" (104) to determine whether a link imbalance caused a reverse link failure to occur. The maximum access probes condition indicates that a wireless unit has attempted to access a base station a pre-defined maximum number of times. The method preferably uses an, indication of a lost paging channel (132) and a traffic channel initialization (TCI) time out (160) to determine whether a link imbalance caused a forward link failure to occur. If the wireless unit did not lose the paging channel (132), the method determines whether a TCI time out occurred (160). If the wireless unit lost the paging channel, or it did not lose the paging channel but a TCI time out occurred, the method determines the cause for the forward link failure. There are two potential causes in this scenario: (1) either the wireless unit is a significant distance from the base station; or (2) the paging channel suffers from significant interference. The method determines the cause and either instructs the wireless unit to perform an idle handoff to a neighboring base station or to exit the digital system.

Abstract: A method, system and apparatus for use in computer-aided design, computer- aided manufacturing, computer-aided engineering and product lifecycle management. An efficient, non-centralized communications framework makes "synchronous" collaborative design possible. Users are resident at workstations that are connected in a peer-to-peer arrangement. In a collaborative design session, the model is resident in memory at each workstation. Modifications are made at any workstation, and commands, which are interpreted at each workstation to effect the modifications, are transmitted over the network. In addition, cell descriptors may be used to identify one or more geometric cells of a model. The cell descriptors are in the form of scripts specifying constraints or filters for identifying cells. The constraints are based on characteristics of items in the model, or associations between items in a model, that are readily discernable to the user, and are therefore easily written and susceptible to easy distribution to other systems.
