Title: Base-triggered release microcapsules
Inventor: LEE KUO-SHIN
IPC: A01N53/08
Filed: 1999-07-28
Granted: 2008-04-08
Abstract: Microcapsules formed from an aminoplast shell wall and an encapsulated ingredient or ingredients enclosed within the wall in which the wall contains a base-cleavable ester moiety. These capsules have been found to be sensitive to the presence of base such that in the presence of base, the capsule walls are relatively quickly disintegrated or degraded so as to produce a relatively quick release of the encapsulated materials. Microcapsules of this invention are particularly suitable for use in controlling insects having an alkaline gut such as certain lepidoptera in that the capsule shell wall may be designed so as to quickly disintegrate under the alkaline conditions present in the gut of the insect thus providing a microcapsule which is safe to handle but which is selectively effective against certain undesirable insects while not harmful to beneficial insects or insects which do not feed on the capsule materials.

Abstract: L'invention concerne un procédé et un appareil (20) permettant de reproduire une structure de surface holographique sur une surface laminée d'un substrat relativement rigide (ST). En particulier, après le montage du substrat (ST) sur une table (24) et le dépôt d'une couche d'époxyde entre le substrat et une sous-bande maîtresse (SU) afin de produire une structure en couches, ladite structure est comprimée, de façon automatique, dans un espacement formé entre la table (24) et une surface extérieure d'un rouleau d'impression rotatif (26), ce qui donne lieu à la reproduction de la structure de surface sur la couche d'époxyde. On laisse alors durcir l'époxyde, et on sépare la sous-bande maîtresse (SU) du substrat (ST) de manière à obtenir une surface laminée pourvue d'une structure de surface holographique sur une surface. On enroule de préférence la sous-bande maîtresse autour du rouleau d'impression, et on fait tourner ledit rouleau (26), pendant que l'on actionne la table (24) d'un mouvement alternatif linéaire. -

Abstract: A source fluid from which solid material forms when it is cooled is passed through apparatus which defines a continuous reentrant lumen (12). The lumen has a thermally conductive processing wall (15) from which heat is extracted from the outside as the source fluid flows through the lumen, resulting in formation of solid material on the inner surface of the lumen wall. A runner (24) circulates around the lumen and dislodges material deposited on the inn er surface of the lumen wall. This material is then carried as solids of a slur ry out of the apparatus with the fluid stream.

Abstract: L'invention concerne des formes de réalisation de pompes à perfusion implantables utilisant un procédé de transformation d'une première substance en une seconde substance gazeuse (par électrolyse par exemple) pour créer une force de motivation destinée à expulser un fluide voulu (drogue ou médicament par exemple) de la pompe au corps du patient. Une poche dilatable peut être disposée autour d'une cellule électrolytique produisant du gaz, de manière que le gaz, à mesure qu'il se dilate, déplace une partie du volume occupé à l'origine par le fluide voulu, et expulse ainsi le fluide de la pompe. Les pompes selon l'invention peuvent être pourvues d'un double septum de manière à permettre la recharge du fluide voulu et l'élimination simultanée du gaz généré par le système en cas d'utilisation d'une aiguille simple. Il est possible de recharger les batteries de la pompe par conduction électrique directe via une ou plusieurs aiguilles et/ou par transfert d'énergie r.f.. Il est possible de programmer la pompe au moyen des voies conductrices que constituent le(s) aiguille(s) ou au moyen d'un transfert r.f.. Un régulateur de pression peut être monté à proximité d'un orifice de sortie de la pompe de manière à permettre un fonctionnement plus fiable de ladite pompe lorsque celle-ci est soumise à des changements de pression ambiante. Une valve anti-reflux peut être utilisée pour éviter tout risque de refoulement dans la pompe.

Abstract: A technique for printing postage and other value indicia at a user location. A user at a user computer acquires secure postage labels having one or more security features such as serrated edges, a microprint strip, a color fiber, taggants, a watermark, a hologram, or a fluorescent stripe. The labels have associated serial numbers, possibly at the sheet or individual label level. The user establishes communication with a postage vendor system (PVS), which may include one or more servers, and requests one or more indicia. The user also provides one or more serial numbers for the label(s) or label sheet(s) on which the one or more indicia are to be printed. The PVS determines if the one or more serial numbers are valid, and if so, generates information for printing the one or more indicia and then sends the information to the user computer. The information preferably includes a digital signature for each indicium, which may incorporate the serial number. The user computer receives the information and prints the one or more indicia on one or more postage labels.

Granted: 2010-01-12
Abstract: The invention disclosed is a Transmission Control Protocol (TCP) transport handler for a network intermediary. The handler examines all segments in a TCP/IP data stream between two nodes. The handler maintains a list of changes made by an application module to a data segment within a data stream and utilizes that list to ensure that the sequence numbers for both receiver and transmitter refer to the same segments of data. The list of changes is also used to reapply changes to retransmitted packets. Data segments are not acknowledged until the receiver acknowledges a segment, eliminating the requirement of buffering data segments.

Abstract: A method and system for commanding and controlling diverse home devices. A first home device capable of displaying user interface data is connected to a home network. A second home device stores user interface data that defines a user interface for commanding and controlling the second home device, also connected to the home network. The first device receives the user interface data from the second device over the network. The first device then displays the user interface as defined by the data. The user interacts with the user interface displayed on the first device by a control device. User input is accepted from the user responsive to the interaction. Control and command information is sent from the first home device to the second home device in order to control the second device according to the user input. Since the user interface can be displayed from any device, a single control device may control a plurality of different devices without requiring any change in the mode of operation of the control device.
