Abstract: To spin a metal sheet around a chuck for forming a product, in a teaching phase involving force control, a product is formed on the chuck by rotating the chuck about the axis of rotation and by moving a forming roller one or several times alongside the chuck with a pre-determined pressure force thereby spinning the intermediate metal sheet. In the teaching phase, measuring data corresponding to the movement of the forming roller during spinning is fixed in a memory of a control unit, and in the production phase the forming roller is controlled with the aid of these measuring data. The control unit determines the position values of the forming roller in axial direction and in transverse direction relative to the chuck from the data fixed in the teaching phase, and the control unit controls the forming roller in the production phase at least during a part of the spinning movement by means of the position values determined in this manner for spinning the metal sheet into the desired product.

Granted: 2000-03-14
Abstract: A flowmeter (M) measures fluid flow in a system and produces a train (Si) of digital pulses representing the measured flowrate. The frequency of the pulses is intended to be proportional to the flowrate. A preamplifier (10) controls generation of output pulses (Fn, Fq) of an output digital pulse train (So). The preamplifier first decodes the digital pulse train using a phase discriminator (14). Output pulses from the discriminator are counted (at 24 and 46) to count the number of pulses and their frequency of occurrence. A frequency multiplier (40) is responsive to the pulses and their occurrence to generate each pulse of the output pulse train. Generation of these pulses involves use of a scaling factor (Vcf) by which meter performance factors, drift, and the fluid flow environment are taken into account. Use of the scaling factor enables the timing and frequency of the generation of pulses comprising the output pulse train to both be controlled so these pulses are produced at a rate which is linearly proportional to the measured fluid flowrate.

Title: Flow cytometer jet monitor system
Inventor: VAN DEN ENGH GER
IPC: G01N15/10
Filed: 1995-10-13
Granted: 2006-07-04
Abstract: A direct jet monitor (66) illuminates the jet of a flow cytometer in a monitor wavelength band which is substantially separate from the substance wavelength band. When a laser is used to cause fluorescence of the substance, it may be appropriate to use an infrared source (67) to illuminate the jet and thus optically monitor the conditions within the jet through a CCD camera (68) or the like. This optical monitoring may be provided to some type of controller or feedback system (34) which automatically changes either the horizontal location of the jet, the point at which droplet separation occurs, or some other condition within the jet in order to maintain optimum conditions. The direct jet monitor (66) may be operated simultaneously with the substance property sensing and analysis system so that continuous monitoring may be achieved without interfering with the substance data gathering and may be configured so as to allow the front of the analysis or free fall area (7) to be unobstructed during processing.

Filed: 1998-02-26
Granted: 2009-04-21
Abstract: L'invention concerne un processeur (100) de signaux numériques utilisé pour des calculs d'annulation d'écho. Ce processeur comprend des multiplicateurs/additionneurs parallèles (102/104 et 106/108), une mémoire d'étalonnage (120) de signal d'entrée, et une pluralité d'accumulateurs (112, 114, 116, 118) pour le stockage temporaire des résultats des calculs effectués. Par conséquent, les résultats des calculs ne doivent pas tous être sauvegardés dans une mémoire de données externe (136, 138), ce qui minimise les goulots d'étranglement du transfert de données et augmente nettement l'efficacité calculatoire du processeur (100) de signaux numériques. Les calculs pour les mises à jour du coefficient du filtre adaptatif peuvent donc se faire beaucoup plus rapidement, ce qui fait que les coefficients du filtre adaptatif peuvent être copiés beaucoup plus rapidement d'un filtre à l'autre. Le processeur (100) de signaux numériques a une complexité calculatoire bien moindre que celle des processeurs de signaux numériques actuels.

Abstract: Multipotent neuroepithelial stem cells and lineage-restricted oligodendrocyte-astrocyte precursor cells are described. The neuroepithelial stem cells are capable of self-renewal and of differentiation into neurons, astrocytes, and oligodendrocytes. The oligodendrocyte-astrocyte precursor cells are derived from neuroepithelial stem cells, are capable of self-renewal, and can differentiate into oligodendrocytes and astrocytes, but not neurons. Methods of generating, isolating, and culturing such neuroepithelial stem cells and oligodendrocyte-astrocyte precursor cells are also disclosed. A method of generating neural crest stem cells involves inducing neuroepithelial stem cells to differentiate in vitro into neural crest stem cells. Differentiation can be induced by replating the cells on laminin, withdrawing mitogens, or adding dorsalizing agents to the growth medium. Derivatives of the peripheral nervous system can be generated by inducing the neural crest stem cells to differentiate in vitro.

Title: Explicit rate computation for flow control in computer networks
Inventor: OUELLETTE MICHEL
IPC: H04L12/56
Filed: 1999-12-07
Granted: 2008-08-05
Abstract: Flow control in a network is implemented based on aggregate traffic measurements. For example, in an ATM network only the aggregate background (CBR/VBR) traffic rate and the aggregate ABR traffic rate are used, in contrast with other schemes that require per-connection rate measurements or variables. An explicit rate is calculated at discrete time instances using a simple proportional controller model. Explicit rate computations can be performed entirely by software, and the interval between computations is large enough to keep the processing overhead required of the switch very low. In addition, methods consistent with the present invention achieve max-min fairness and MCR plus equal share in a natural way without any additional computation or information about bottleneck rates.
