Une étiquette RFID comprend une plage de connexion de l'antenne, une récepteur, un automate fini, une pompe de charge et un modulateur. Le récepteur est couplé à la plage de connexion de l'antenne, reçoit un symbole de la plage de connexion de l'antenne et émet un signal reçu. L'automate fini est conçu pour déterminer un symbole de réponse du signal reçu et un état de fonctionnement de l'étiquette. Le modulateur, qui est couplé à la plage de connexion de l'antenne, est conçu pour moduler en rétrodiffusion le symbole reçu avec le symbole de réponse. En outre, le modulateur est conçu pour transmettre le symbole modulé en rétrodiffusion à la plage de connexion de l'antenne. La pompe de charge est conçue pour convertir un signal haute fréquence reçu en une tension sensiblement continue (DC).

Title: Device for positioning a movable instrument, especially a laboratory or climatic test cabinet, on a track
Inventor: LOSCHER HELMUT
IPC: B01L99/00
Filed: 2004-04-28
Abstract: The positioning device according to the invention has a base plate, which can be laid on a track. At least one stop block is attached to this base plate. This block has first means acting on its bottom side during sliding of a movable instrument for its transfer into a position that is raised relative to the track and second means for fixing in the raised position. The positioning device has the advantage that it can be placed without contact with other neighboring components in a system on the track into the desired position. A  movable instrument according to the invention provides a chassis and a housing structure resting on this chassis. The chassis has wheel units and at least one sliding element, which is assigned to a stop black of a positioning device and is attached to the bottom side of the instrument.   During sliding, the sliding element meets the stop block and is set in an active connection with first means for transferring the instrument into a raised position and when the raised position is reached, it is set in an active connection with two means for fixing the instrument.   A movable instrument of this type has the advantage that the pressure forces occurring during centering due to the sliding on the stop blocks of the positioning device do not act directly on the housing structure, but instead via the support chassis.

Abstract: A readily portable facility and method for manufacturing houses or other buildings in the readily portable facility for later transportation and installation of the house to a foundation site, the readily portable facility being located within or proximate to a subdivision or other location at which the houses or buildings are to be installed. The portable facility can accommodate methods of manufacturing houses or buildings which utilize traditional stick building methods or production lines therein. The readily portable facility is designed to be a selectively highly mobile facility, wherein, when the completed or substantially completed houses or buildings have been placed at the installation location, the readily portable facility can then, if the need arises, be quickly disassembled and removed from its location closely proximate to the installation location, transported to a new manufacture site, and then quickly erected to begin manufacture of additional completed or substantially completed houses or other buildings at a new installation location. Further, since the portable facility comprises a covering fabric or other material placed over a support framework, a naturally bright interior is created within the readily portable facility.
