Abstract: Method and system thereof for transmission of several coherence division multiplexed (CDM) optical signals via one wavelength division multiplexed (WDM) transmission channel of a multichannel WDM telecommunication system to extend the network capacity to a theoretical limit. A broadband optical source generates light within the spectral range of at least one WDM transmission channel. Several CDM channels share this spectral range to transmit and detect phase modulated optical signals through optical fiber links.

Abstract: Center cores are formed by extrusion-molding ABS resin. Seven pieces of the center cores, which are juxtaposed to each other in the horizontal direction, are supplied by a pultruder, and reinforcing long-fibers impregnated with an unsaturated polyester resin are allowed to pass through dispersion guides and squeezing nozzles, to thus squeezing-mold a fiber-reinforced composite hollow structure having FRP made legs. A final squeezing nozzle is disposed in a cross head die through a cooling jacket, and the hollow structure thus molded is allowed to pass therethrough to be covered with the ABS resin in a state in which the outer periphery of the hollow structure is heated. The hollow structure thus covered is subjected to cooled-sizing through a plurality of horizontal and vertical pairs of rollers, and then cured in a hot curing tank. The surface covered with the ABS resin is subjected to a surface-treatment of imparting irregularities for giving an antislipping function to the surface.

Spectral lines are substantially narrower than the spectral separation between the lines.

Abstract: Dynamic force measurement methods and systems for measuring forces applied to a structure by use of accelerometers attached to masses of the structure supported by one or more load cells. A load cell signal is combined with a summation of the accelerometer readings multiplied by the corresponding attached masses to produce a measurement of a force applied to the structure. An unknown applied force f(t) is determined by summing the load cell measured force with all other forces that exist between the load cell and the unknown force. The methods and systems can be employed in any type of load or force measuring machine or device.

Abstract: An attachment gusset with ruffled corners and method and machinery for manufacture provides a gusset formed of a continuous strip of material which is pleated at corners or turns in direction of the gusset to form ruffles which are attached to an adjacent layer of material. The ruffled gusset lies substantially flat against adjacent layers of material to which it is attached in a pressed state, and can be expanded to accommodate dimensional structures, such as cushioned pads. The number and spacing of pleats can be adjusted according to the radius of the corners or turns in the gusset. In a method of construction of the gusset, the pleats are formed as the material to which the gusset is attached is turned relative to the sewing point of attachment.

Abstract: An EEG electrode system for establishing positive electrical contact with the scalp, uses absorptive electrode wrap material in contact with metallic electrodes, with saturated electrode wrap material placed in contact with the scalp. Saturation of the electrode warp material with a conductive solution such as saline provides mechanically and electrically stable contact at multiple scalp electrode sites. An electrode wrap holder assembly holds the electrode wrap and an exposed portion of the electrode wrap in contact with the scalp, while providing access to the electrode wrap for re-wetting with the conductive solution if required. The electrode wrap holders are mounted in straps, hard caps or other headgear. Adjustment of the electrode wrap holders within the mounts further compresses the flexible, absorptive electrode wrap, causing flow of the conductive solution therein and enhancement of the electrical contact.

Abstract: A system and method for collecting, inventorying, stocking and performing metered delivery of standard parts to an assembly operation. Standard parts are collected from multiple suppliers in an optimized pick-up route, and delivered to a standard parts metering warehouse. The standard parts are broken down into production shift quantities based upon production data of the assembly operation. The production shift quantities of standard parts are labeled according to part type or identity and a drop zone within the assembly operation. The standard parts are then stocked in the metering warehouse according to an optimized route which corresponds to a drop zone delivery sequence in the assembly operation. Limited production shift quantities of standard parts are then metered from the metering warehouse in accordance with a production schedule of the assembly operation, and delivered directly to pedestals at workstations at the corresponding drop zones in the assembly operation.

Abstract: A local computer stores a current program such as an operating system or an application. A network server stores a latest program which is a latest version of the current program, and an identifier program for generating an identification corresponding to the latest program upon interrogation. An updater program is alternatively stored on the local computer or the network server for causing the latest program to be transferred from the network server to the local computer and replace the current computer program. The current program and the latest program each include a startup program configured to interrogate the identifier program, determine if the identification corresponds to the current program, and if the identification does not correspond to the current program, run the updater program.

Abstract: An adaptive bias control scheme for an Orthogonal Frequency Division Multiplex (“OFDM”) transmitter. The transmitter chain is comprised of class A amplifiers. The amplifiers in the transmit chain are backed off from P1dB to ensure linear amplification of the signal. Amplifier back off is defined as (Amplifier P1dB) minus (Average Signal Power). Since the efficiency of the amplifier decreases in direct proportion, to the back off, it is desirable to minimize back off while maintaining linearity. The back off is dependent on the peak to average power ratio (“PAPR”) of the OFDM waveform. The PAPR is measured on a symbol by symbol basis and the amplifier P1dB is adjusted in proportion to the PAPR of the symbol, maintaining a P1dB sufficient to provide the required back off dictated by the maximum PAPR of the OFDM waveform, but can be lowered for symbols with PAPR below the maximum.

A Feature Control Frame (FCF) for each datum feature that is intended to eliminate roll about a fixed primary axis of the DRF includes a material location modifier which specifies whether the orientation or the location of the feature should be used to eliminate roll. The material location modifiers enable specification of Independent of Material Location (IML), at Basic Material Location (BML), at Maximum Material Location (MML) and at Least Material Location (LML), eliminate all ambiguity in the formal drawing, and enable a DRF to be constructed automatically using a computer. The material location modifiers further eliminate any possibility of misinterpretation of the formal drawing during all stages of manufacture and inspection of the part.

Abstract: In a computer implemented learning and/or process control system, a computer model is constituted by the most currently fit entity in a population of computer program entities. The computer model defines fitness as a function of inputs and outputs. A computing unit accesses the model with a set of inputs, and determines a set of outputs for which the fitness is highest. This associates a sensory-motor (input-output) state with a fitness in a manner that might be termed “feeling”. The learning and/or control system preferably utilizes a Compiling Genetic Programming System (CGPS) in which one or more machine code entities such as functions are created which represent solutions to a problem and are directly executable by a computer. The programs are created and altered by a program in a higher level language such as “C” which is not directly executable, but requires translation into executable machine code through compilation, interpretation, translation, etc.
