Abstract: In an automatic predistortion adjusting circuit, a splitter splits an input signal into first and second signals.      A predistortion circuit applies first non-linear characteristics to the first signal, a variable attenuator adjusts an amplitude of an output signal of the predistortion circuit, a variable phase shifter adjusts a phase of an output signal of the variable attenuator, and a main amplifier amplifies an output signal of the variable phase shifter, so that second non-linear characteristics opposite to the first non-linear characteristics are applied to an output signal of the main amplifier. A directional coupler takes out a part of an output signal of the main amplifier as a branch signal, and a delay line delays the second signal. An adder adds a delayed signal passed through the delay line to the branch signal.      Further, a detector detects a strength of an output signal of the first adder, and a control circuit controls the first non-linear characteristics, an attenuation amount of the variable attenuator and a phase amount of the variable phase shifter in accordance with an output signal of the detector.

Abstract: A single transducer digital communication receiver is described which is capable of extracting the data bits of at least one desired signal in the presence of interfering signals of similar type. The present invention also seeks to provide a communication system in which overlapping transmissions are tolerated and allowed. The present invention describes a design for a digital communication system, according to a specific frequency plan, which includes an appropriate digital demodulator that extracts the data bits of the desired signal(s) in the presence of closely spaced signals. The present invention enables reduced channel spacing in digital communication systems and thereby increases the system capacity (i.e. the number of users per bandwidth unit) without incurring any significant loss in system performance (e.g. power margins, BER, and channel availability). It also allows a reduced power margin that is required to maintain a pre-specified performance level without sacrificing system capacity. These two factors, power margin and system capacity, play a central role in the design and construction of state-of-the-art digital communication systems which seek to pack more users on the same frequency band without incurring significant power loss. Thus, the present invention also provides a method and apparatus for upgrading existing systems such as a cellular system for mobile wireless communications that is based on the IS-54 or the GSM standard.

Abstract: Cette invention concerne un procédé et un dispositif permettant d'effectuer un joint dans un article allongé constitué d'une matière thermoplastique, tel qu'une main courante d'escalier mécanique (120) ou une courroie transporteuse, qui peut comporter entre autres une pluralité de câbles de renforcement et un tissu assurant le glissement. On maintient les extrémités de l'article (20) dans un moule (12) et on les chauffe de façon à refondre la matière dont l'article est composé. On refroidit des parties adjacentes aux extrémités, au niveau des extrémités du moule, afin d'empêcher leur refonte. Les extrémités en fusion se réunissent alors et l'on refroidit le joint en fusion pour solidifier ladite matière et réaliser le joint. Lorsque des câbles de renforcement (126) sont présents, on peut couper ceux-ci suivant un modèle d'entrelacement, qui est avantageusement disponible dans une seule couche de l'article plutôt que disposé à travers toute la profondeur de l'article. On peut remplacer une couche supérieure (160) par un capuchon supérieur distinct constitué de la matière composant le corps de l'article. Lorsqu'un organe glissant est présent, on coupe, afin d'assurer un effet d'entrelacement efficace, une couche inférieure ou une partie de la main courante suivant une direction inclinée, de façon à former un joint incliné dans l'organe glissant.

Title: Method and apparatus for three-dimensional micro-fabrication and processing on flexible filamentary substrates
Inventor: JACOBSEN STEPHEN C
IPC: C23C14/50
Filed: 1999-02-09
Granted: 2007-06-05
Abstract: A fixture apparatus for material deposition or processing on a long, flexible, nonplanar, filamentary substrate has a tubular member for holding the filamentary substrate rotatably disposed on a base. An opening is formed in the tubular member through which material is deposited on the surface of the filamentary substrate. Moveable tubes are each slidingly disposed in the tubular member on either side of the opening. The tubes and/or the tubular member hold the filamentary substrate on both sides of a deposition area on the substrate to maintain the straight configuration of the long, flexible, filamentary substrate. The tubes and/or tubular member also physically masks the filamentary substrate to prevent material deposition outside the deposition area on the substrate. The base has a circular path and a rotating member. A wheel is coupled to one side of the tubular member and is rotatably disposed on the circular path of the base. The other side of the tubular member is rotatable coupled to the rotating member of the base by a bearing. The rotating member causes the wheel to turn about a vertical axis in a circular path. The wheel is fixed to the tubular member causing the tubular member to rotate about a horizontal axis or longitudinal axis of the tubular member. As the rotating member turns and the wheel rolls, the tubular member the filamentary substrate is rotated about the two different axes to uniformly deposit material on the filament.

Granted: 2006-07-25
Abstract: A diagnostic test unit for deterministically measuring one or more parameters, such as dead band, dead time, response time, gain, or overshoot, of a process control device that is connected in a process control loop during operation of a process includes a switch controller, a signal generator, a switch, a response accumulator mechanism, and an analyzer mechanism. The swtich controller monitors a process signal during operation of the process to determine whether the process signal is substantially stable. In the event that the process signal is substantially stable, the switch replaces a control signal with a diagnostic test signal generated by the signal generator. The response accumulator is in communication with the process control loop to obtain an indication of the response of the process control device to the diagnostic test signal. The analyzer unit then determines the device parameter from the test signal and the response indication.
