Title: Motor control usable with high ripple bemf feedback signal to achieve precision burst mode motor operation
Inventor: MORRIS ANDREW R
IPC: H02P7/29
Filed: 2002-12-09
Abstract: A motor control technique, which may be implemented in a motor drive unit of a sheet material dispenser, permits precise control of motor operation amounts within short intervals ("bursts") of motor operation. The technique marries "bang-bang" motor speed control with a variable power motor drive system, e.g., a pulse width modulation (PWM).  Motor speed is sensed by turning the motor off and waiting for the resulting inductive kick to die out. Then, a voltage threshold detector detects whether the back electromotive force (BEMF) of the motor is above a threshold corresponding to a motor speed setting. A PWM drive is preferably set up to have a predetermined number of power levels, e.g., nine.  The motor speed is repeatedly sampled and if the speed sensing voltage is above the threshold, the PWM is brought down to the next lower power level. If. the speed sensing voltage is below the threshold, the PWM is brought up to the next higher power level. So configured, the system "bangs" up and down between adjacent power levels, instead of between zero and maximum power. Adjustments in the duration of a motor operation cycle are made in conjunction with the power level adjustments, to compensate for any power level adjustment that is not averaged out within the motor operation cycle. As a result, motor operation amounts may be closely controlled. Motor operation is far smoother and wasted power is reduced as compared to a conventional "bang-bang" system. Response times may be substantially improved relative to known feedback control systems, such as PID control, and the need for external speed monitoring transducers (i.e., "pick-off" devices) is eliminated.

IPC: H04B10/272
Filed: 2001-06-29
Abstract: L'invention concerne un système et un procédé permettant d'augmenter la capacité d'un canal dans des réseaux de communications par fibre optique utilisant une modulation spatiale et temporelle. Le système utilise un champ spatial tridimensionnel de multiplexage temporel, de modulation de polarisation, et de multiplexage par répartition en longueur d'onde afin d'augmenter la capacité d'un canal. Une pluralité de processeurs émetteurs de données reçoivent une pluralité d'entrées de canaux destinés effectuer une transmission sur le réseau optique. Ces processeurs émetteurs de données exécutent le multiplexage temporel d'une pluralité d'entrées de canaux de données en une pluralité de trains de données temporelles et spatiales. Une pluralité de sources optiques reçoivent et modulent directement la pluralité de trains de données temporelles qui sont ensuite modulées par polarisation avant d'être distribuées à un multiplexeur par répartition en longueur d'onde pour transmission sur un câble à fibres optiques. Ledit câble à fibres optiques distribue des longueurs d'onde à un multiplexeur par répartition en longueur d'onde pour polarisation, démodulation, photo-détection ultérieures de la pluralité de trains de données temporelles qui sont ensuite distribuées à un processeur récepteur de données pour un multiplexage temporel des données temporelles. Une variante permet d'utiliser une connexion transversale pour réutiliser les longueurs d'onde. Le système peut également s'appliquer à des réseaux bouclés, à des réseaux à coupleur en étoile, et des réseaux de bus de données constitués de multiples unités d'interface de réseaux communiquant sur une fibre optique.

Inventor: CLEMENTS MARTIN A
IPC: F01C21/08

Abstract: Vane pump (10) mechanical losses are reduced by removing vane friction losses and replacing them with lower magnitude journal bearing fluid film viscous drag losses. A freely rotating cam ring (70) is supported by a journal bearing (80). A relatively low sliding velocity is imposed between the cam ring and the vanes (26). This permits the use of less expensive and less brittle materials in the pump by allowing the pump to operate at much higher speeds without concern for exceeding vane tip velocity limits.

Inventor: STERNLIEB HERSCHEL
IPC: D04H1/46
Filed: 2002-07-01
Abstract: A method for hydroenhancing fabrics is described. The method uses the force of pressurized liquid passing through elongated orifices (40) and impinging on the fabric (4). The pressurized liquid exits in a coherent or columnar fashion from elongated orifices that are generally rectangular or linear in shape. The elongated orifices can be arranged so as to produce various effects on a web of fabric, including striping, graduated shading and seer-suckering. The elongated orifices also facilitate the hydroenhancement of high-warp-count fabrics without streak or moire effects. Liquid filtration can be relaxed without clogging the orifices, because the elongated orifices permit larger solid objects to pass. The use of elongated orifices also enhances the energy efficiency of the hydroenhancement process.
