Granted: 2006-04-11
Abstract: Cette invention porte sur un ensemble marqueur pour surveillance électronique d'articles (EAS), ainsi que sur un procédé de conditionnement et de distribution d'un grand nombre de marqueurs individuels ferromagnétiques pour EAS. Cet ensemble peut être, notamment, utilisé avec un système d'insertion automatique ou semi-automatique de marqueur. Chaque coté de ces marqueurs est pourvu d'une couche adhésive ce qui permet de fixer ceux-ci entre les pages d'un livre. L'ensemble comporte plusieurs marqueurs reposant sur un revêtement de séparation à décollement différencié. Une fois achevé, cet ensemble se présente sous l'aspect d'un rouleau ou d'une pile. Lorsque le rouleau est enroulé ou que plusieurs feuilles de marqueurs constituent une pile, la face à décollement aisée du revêtement de séparation à décollement différencié entre en contact avec l'une des couches adhésives tandis que la face à décollement difficile du revêtement de séparation à décollement différencié entre en contact avec la couche adhésive située sur l'autre coté du marqueur. Lorsque le rouleau est déroulé ou lorsque des couches se séparent individuellement de la pile, la face à décollement aisé du revêtement de séparation à décollement différencié se désolidarise de la couche adhésive alors que la face à décollement difficile du revêtement de séparation à décollement différencié reste fixée à sa couche adhésive. De la sorte, une couche de bandes de marqueurs se trouve placée sur le dessus d'un revêtement de séparation. Le revêtement de séparation à décollement différencié permet le déroulement du rouleau ou la séparation des couches distinctes de marqueurs de la pile tout en maintenant les bandes de marqueurs en place sur la face à décollement difficile pour une collecte automatique des bandes et leur séparation une par une au moyen d'un système automatique d'insertion.

Abstract: A software implementation of a modem, particularly designed to execute on a general purpose host processor (102), controlled by a non-real-time, multi-tasking operating system (OS), such as the Windows 95 OS. The software modem is scalable and portable. In this fashion, communications protocols (particularly datapumps) may be easily added to, or removed from, the system, and the modem may be easily adapted for use on other types of processors and operating systems. The controller and datapump portions execute as a plurality of interacting subsystems, each of which can execute at least one of several priority levels. A HRT level routine is responsible for handling an ASIC (106) that buffers transmit and receive samples destined to and received from the phone lines (116). A SRT level task includes logic that needs time functionality, but which is not time critical like the HRT logic. BRT routines execute in an event-driven basis and are used for many controller functions.

Abstract: A hand crank for actuating a gear assembly mechanism such as for a lifting jack is described. The hand crank comprises an elongated metal primary handle, a tube bent at very precise angles to define two spaced-apart handle portions, separated from one another in parallel planes, by a central portion. A connector includes a bracket that has a V-shaped slot to secure the hand crank to a gear actuator at two alternate working positions and a storage position. When in the first position, the handles of the hand crank are parallel to a longitudinal axis of the actuator and define a high-speed position. When in the second position, the two handle portions are parallel to the longitudinal axis of the actuator. The handle portions are spaced about 8.5 inches from one another and about the same distance apart to constitute an ergonomic disposition when used at their first position. In the second position, the central portion lies at an angle when used at their first position slightly less than 90° from the horizontal axis to maintain the connector rigidly secured and the outer handle portion acts as the cranking lever.
