Title: Instrument for test and measurement of atm network virtual connections
Inventor: VANDERVORT COLE S
IPC: H04L12/70
Filed: 1996-11-15
Abstract: A test instrument for monitoring operation of ATM communication networks is capable of identifying individual cells passing through a node to which the instrument is connected as belonging to a particular virtual connection, and transmitting test cells replacing the identified cells, transmitting modified identified cells, or augmenting cells transmitted over the identified virtual connection with operations, administration, and maintainance cells.

Abstract: Charged toner is transferred form an image member to a web of imagable material, such as paper, using an impression cylinder without toner back scatter even at high speed. (e.g. more than 150 feet per minute) movement of the paper. A nip is provided between the image member and the impression cylinder. Toner having a first polarity is applied to the image member, and a second face of a paper web is moved into contact with the image member adjacent the nip so that toner transfers from the image member to the web face. An electric potential of a first polarity is applied to the web at the first face prior to and adjacent the nip, the potential of sufficient intensity so as to substantially prevent back scatter. The electrical potential may be applied using an electrical conductive electrode biased (e.g.  with a spring) into contact with the first face of the paper web, and connected up to a power supply of a first polarity. Alternatively, the electrical potential may be applied using a corona generating device connected to a power supply of the first polarity and shielded from the impression cylinder.

Abstract: L'invention a trait à un procédé de conversion d'enregistrements et au dispositif correspondant, comportant un moteur de conversion, implémenté, de préférence, par un logiciel, qui reçoit des enregistrements formatés d'entrée provenant d'un dispositif de production d'enregistrements d'entrée, convertit ces enregistrements en un format différent (universel) en temps réel et, en fonction du ou des dispositifs hôtes de sortie, en format spécifique de sortie, puis transmet les enregistrements convertis au dispositif hôte de sortie si ce n'est à plusieurs. Des messages, une information en l'occurrence, en provenance d'un ou de plusieurs dispositifs hôtes de sortie, peuvent également être transférés par le biais du dispositif de conversion vers les dispositifs de production d'enregistrements d'entrée. Parce qu'il traite rapidement des formats d'enregistrements nouveaux et/ou incompatibles, le dispositif selon cette invention permet de réduire à leur minimum les coûts de gestion de systèmes de gestion d'information et optimalise leur utilisation. L'architecture d'entrée et de sortie du dispositif de conversion est souple et il est possible d'utiliser ce dispositif de conversion avec de multiples dispositifs (mis en réseau ou non) de production d'enregistrements d'entrée ainsi qu'avec un seul dispositif de stockage d'enregistrement, voire avec plusieurs de ces dispositifs, utilisant plusieurs formats de sortie d'enregistrements.
