Title: Systeme de nettoyage d'une surface pour en enlever des particules
Inventor: LARSEN GARY R
IPC: B08B1/00
Filed: 1996-05-06
Granted: 2001-04-24
Abstract: L'invention concerne un système servant à imprimer un déplacement alternatif axial à un rouleau adhésif (18) (rouleau de nettoyage par contact ou CCR) à travers un substrat (12) que le rouleau est en train de nettoyer, afin d'étendre les particules qui ne sont pas réparties uniformément sur la surface (14) du substrat, sur une zone plus large de la surface de ramassage du rouleau adhésif, ce qui diminue la vitesse de dégradation de l'efficacité de ramassage, tout en améliorant la propreté moyenne du substrat traité et prolonge la durée de fonctionnement du rouleau adhésif entre ses renouvellements. Le rouleau peut être en contact ou non avec la surface pendant son déplacement alternatif. Ce système comporte un deuxième CCR (28) fonctionnant alternativement avec le premier CCR, de sorte qu'au moins un rouleau nettoie le substrat pendant le renouvellement de l'autre rouleau. Le système peut être conçu avec des CCR présentant une largeur totale et chevauchant constamment les deux bords d'une surface pendant le déplacement alternatif. Il peut également comporter des CCR plus courts afin de ne nettoyer qu'une partie d'une surface, par exemple, le long d'un seul bord, ainsi que des CCR sensiblement plus courts que la largeur du substrat, qui peuvent être programmés pour effectuer un déplacement alternatif périodique à travers la totalité de la largeur du substrat. Le système est utile pour le nettoyage de substrats de pièces, telles que des bandes ou des feuilles, et peut également servir à traiter des éléments de machine, tels que des rouleaux de calandre, des rouleaux de revêtement, des rouleaux de transport et d'autres CCR présentant des surfaces moins adhésives.

Title: Adaptive digital radio communication system
Inventor: MACLELLAN JOHN AUSTIN
IPC: H04B1/16
Filed: 1998-09-30
Granted: 2002-08-13
Abstract: The present invention involves an adaptive digital radio communications architecture which can be reconfigured by reprogramming at least one programmable device, and thus more efficiently use the available bandwidth of a time-varying RF channel and/or to provide a flexible and adaptive digital communications system. In certain embodiments, the programmable device uses a Programmable Logic Device (PLD) to perform the digital communications processing functions of the transmitter or the receiver of a radio communications system. In this context, PLD is a general term representing a family of programmable logic devices; examples of this family are a Programmable Array Logic (PAL), a Complex PLD (CPLD), and a Field Programmable Gate Array (FPGA). The architecture is reconfigurable in the sense that any or all of the digital communications processing algorithms can be modified by reprogramming the PLD. The architecture of the digital communications system can be characterized by the following parameters; the channel symbol rate, the occupied bandwidth, the modulation technique, and the multiple access technique. A reconfiguration is a modification of the architecture of the digital communications system, and can occur by reprogramming the PLD through external control, for example in the event a radio communications base station wishes to change the radio architecture being used for a particular piece of radio spectrum. A reconfiguration can also occur, for example, by dynamically reprogramming the digital communications system depending upon time-varying radio channel conditions, such as the effect of the number of channel users, the offered load, quality of service measurements, or the characteristics of the desired application(s), including voice, data, video and/or tracking. Methods to measure the time varying radio channel conditions are disclosed, and further how those measurements can impact a reconfiguration. This invention discloses how the architecture for the digital communications system can be dynamically reprogrammed based upon current channel conditions and/or through external control.
