Abstract: A multi-media messaging system (106) provides multi-media message access capability to non-subscriber message recipients (126) who lack multi-media message-reception capability. When a message originator (100) who is a subscriber requests a message to be sent to a recipient's address, the messaging system determines whether the recipient is able to receive at this address all of the media in which the message is expressed. If not, the messaging system saves the message for the recipient, assigns an identifier/password to the message, and creates a substitute message containing any components of the original message that are expressed in media which the recipient is able to receive at the address, along with the password and instructions on how to log into the sending messaging system. The messaging system then sends this substitute message to the recipient's address. When the recipient follows the instructions and logs into the sending messaging system with the password, the messaging system allows the recipient to access only the original message. Following this access, or if the access is not made within a predetermined time period, the messaging system deletes the original message.

Abstract: Bande ou étiquette utile pour fermer un récipient, cette bande ou étiquette apportant la preuve visuelle de l'ouverture par la force de la fermeture ou du refroidissement en deçà d'une température de rupture. La bande comprend une feuille plastique (20), une couche d'encre (22) imprimée sur une surface de la feuille plastique et une couche d'adhésif sensible à la pression (24). La bande peut être intégrée dans un sac (10) afin de fermer ce dernier. La bande comporte une couche d'encre qui est intercalée entre la feuille plastique et la couche adhésive. L'adhésif peut être placé sur des parties du sac pour le souder et le fermer de cette manière. Si la fermeture est forcée, la couche d'encre se décolle visiblement de la feuille plastique. La couche adhésive et la feuille plastique sont sélectionnées de manière à avoir des vitesses de rétrécissement différentes lorsqu'elles sont refroidies, de sorte que lorsque la bande est refroidie en deçà de sa température de rupture, la couche d'encre se décolle. Dans une autre forme de réalisation de la bande, les deux couches d'encre sont imprimées sur la feuille plastique. La première couche d'encre est transparente et imprimée sur la feuille plastique non traitée avec un motif. La deuxième couche d'encre est opaque et imprimée uniformément sur la feuille plastique et l'encre transparente située après la feuille plastique est traitée.

Title: Field marker for agricultural implement
Inventor: HUNDEBY DAVID
IPC: A01B61/04
Filed: 1998-10-30
Granted: 2006-05-30
Abstract: A field marker for mounting on an agricultural implement includes an elongated arm adapted to project outwardly laterally of the implement when in its operating position and is adapted to carry a field marking device at its outer distal end for making a score mark on the ground. A mount for the arm at an inner proximal end thereof allows pivoting of the arm about first and second transverse axes whereby to allow the arm to swing upwardly and downwardly about the first one of said axes when operating on uneven ground while also allowing the arm to swing around the second one of said axes from its outwardly projecting operating position into another position. The arm includes inner and outer arm sections secured together by a folding joint to permit the inner and outer arm sections to be folded into juxtaposition with one another and brought into the transport position. An extensible actuator effects relative rotation of the inner and outer arm sections, and a mechanism interacts with the inner and outer arm sections and the actuator such that as the inner arm section is pivoted through a selected angle, the outer arm section is pivoted about said folding joint relative to the inner arm section. A breakaway link on the arm permits the arm to swing as a whole relative to the mount about the second axis away from its outwardly projecting operating position when an obstacle is encountered and a predetermined force on said arm has been exceeded. The breakaway link has a resetting device associated therewith for returning the arm to the operating position once the obstacle has been cleared.

Title: Amplified sensor arrays
Inventor: WAGENER JEFFERSON L
IPC: G01D5/32
Filed: 1997-07-10
Granted: 2006-05-30
Abstract: The present invention significantly improves the signal to noise ratio (SNR) in a passive optical array comprising sensors (110) located in rungs between a distribution bus (100) and a return bus (120).  Erbium-doped optical fiber amplifiers (130, 132) are included in the buses proximate to each rung coupling to offset the coupler splitting losses. The gains of the amplifiers are selected to offset losses due to the couplings. The overall SNR can be maintained without significant degradation even for large numbers of sensors. In one aspect of the present invention, the amplifiers are located along the distribution and return buses directly after the couplers (140, 142), except for the last coupler. In a second aspect, the amplifiers are located directly before each coupler. The optical amplifiers preferably are made of short lengths of erbium-doped fiber spliced into the distribution and return buses.
