Title: Enhanced parking meter utilizing user identification technology
Inventor: BAHAR REUBEN
IPC: G07B15/02
Filed: 2002-12-28
Abstract: An enhanced parking meter system utilizing user identification technology to achieve improved efficiencies in the enforcement and regulation of parking meters. A user and/or vehicle is identified by communication of user data into the parking meter system. If the meter becomes expired with the vehicle remaining in the parking space, a citation will be electronically processed, in accordance with the user data, and thereafter delivered to the user or vehicle owner. Recognition of the user and/or vehicle further enables the system to limit the individual's and/or vehicle's parking time in front of a particular meter or designated cluster of meter. This would help regulate traffic within a municipality district as well as prevent people from parking in a metered location for excessive periods of time.

IPC: B60D1/02
Filed: 2004-12-03
Abstract: The present invention relates to a quick and easily released hitch pin used for securing the coupling of a trailer or similar implement onto a trailer hitch. The hitch pin comprises a guide member, pin member and handle. Linkage means provided in the pin member connecting the guide member and the handle, allows for the handle to coordinately move the guide member between a first position, where the handle and guide member are substantially aligned with the pin member, and a second position where the handle and guide member form an angle to the pin member. When the handle and guide member are in the first position, the hitch pin can be easily inserted through a hitch orifice. Once positioned in the hitch orifice, the handle can be physically, or by the force of gravity, moved to the second position to limit lateral movement of the hitch pin through the hitch orifice.

Abstract: L'invention concerne un débitmètre inductif pour fluides électriquement conducteurs comportant une section de conduite d'écoulement isolante de section circulaire, une paire d'électrodes diamétralement opposées et électriquement couplées par le fluide électriquement conducteur, et un système de génération de champ magnétique. Ce système de génération de champ magnétique comprend la section de conduite d'écoulement à angle de contact déterminé et il génère un champ magnétique à orientation de ligne de champ sensiblement perpendiculaire aux droites de liaison entre les électrodes de mesure et perpendiculaire à l'axe longitudinal de la conduite d'écoulement. L'invention vise à augmenter l'insensibilité à des valeurs de mesure faussées en raison de modifications du profil d'écoulement dans la section de conduite dépendantes de la vitesse d'écoulement ou bien en raison d'un profil d'écoulement asymétrique relativement à l'axe médian de la conduite d'écoulement. A cet effet, des ensembles de surfaces actives, notamment des éléments plats, sur lesquels les lignes de champ du système de génération de champ magnétique traversent de manière limitée la paroi intérieure de la conduite d'écoulement, sont mesurés de telle manière que, dans une représentation de la paroi intérieure de la conduite d'écoulement, des droites de référence tangentielles placées sur les ensembles de surfaces actives convergent par paires en direction de l'emplacement des électrodes correspondantes, ces droites tangentielles étant incidentes de l'extérieur en deux points avec les ensembles de surfaces actives. Entre deux points de contact se trouvent des zones concaves où les lignes de délimitation des ensembles de surfaces actives n'ont aucun point de contact avec les droites limitatives tangentielles.
