Abstract: A system for inspecting an object, the system comprising a camera; a work surface for receiving the object; and an apparatus for processing an image of the object taken by the camera wherein, during the capture of an image by the camera, the camera and the object are fixed with respect to one another. The processing apparatus identifies those image data components that represent the an edge of the object in an image plane, and projects each image edge data component onto the object plane. The processing apparatus also determines whether each object edge data component relates to an edge of the object that lies on the work surface or to an edge of the object that is spaced apart from the work surface and, upon determining that an object edge data component is spaced apart from the work surface, adjusts the value of the object edge data component by an amount depending on the ratio of the size of the object in a direction generally perpendicular with the work surface to the perpendicular distance of the camera's focal point from the object plane.

Title: Vffs filler for large pouches
Inventor: BASQUE ROLAND
IPC: B65B9/213
Filed: 2004-01-07
Granted: 2011-11-08
Abstract: A vertical pouch forming, filling and sealing machine (10) and method for making pouches (22) and filling same with a liquid content in the range of about 5 to 20 liters, is described. As a pouch is being filled with a liquid (49) it descends into a support cage (47) to restrain the pouch (22) from ballooning out and prevents the weight of the liquid in the filled pouch from tensioning the film (14) in the hot horizontal seal zone of the horizontal sealer (21). The support cage (47) compensates for loss of surface tension of the film in the hot horizontal seal zone during the horizontal sealing cycle.  The cage (47) also has a gate section (56) to discharge the filled pouch by gravity after the horizontal sealing cycle.

Patent CA-2481551-C (CA)
Inventor: ROUSE GORDON F
IPC: G01P5/12

Granted: 2013-05-28
Abstract: A differential pressure-induced airflow based approach is used to measure Angle~Of-Attack (AOA) or Angle-Of-Sideslip (AOS) for an aircraft. Ports on opposing sides of an aircraft fuselage are coupled by an airway incorporating a mass airflow sensor. As the relative wind's angle of incidence changes direction with respect to the aircraft's longitudinal axis or wing chord, a differential pressure is created. The differential pressure induces an airflow between the ports whose magnitude is measured by a mass airflow sensor. The resulting airflow is a function of the respective AOA or AOS. The measured airflow and air data computer supplied parameters of airspeed (or dynamic pressure) and altitude (or static pressure) are utilized by an algorithm that reduces the data into angular AOA or AOS measurements.

Title: Method for selecting an operating mode based on a detected synchronization pattern
Inventor: STOGNER DARRELL J
IPC: H04J3/06
Filed: 2004-04-29
Granted: 2009-04-07
Abstract: A received synchronization pattern is compared against first and second known synchronization patterns. If the received pattern is substantially similar to the first known pattern, the payload is processed as voice; and if the received pattern is substantially similar to the second known pattern, the payload is processed as non-voice. Alternatively, a target synchronization pattern dependent on an operating mode is selected. The received pattern is compared against the target pattern. If the received pattern is substantially similar to the target pattern, the payload is processed; otherwise, the burst is discarded. In yet another alternative, the received pattern is compared against first and second known synchronization patterns having a common length. If the received pattern is substantially similar to the first known pattern, a first operating mode is selected, and if the received pattern is substantially similar to the second known pattern, a second operating mode is selected.

Granted: 2013-05-28
Abstract: Cette invention se rapporte à un procédé de mutagenèse, grâce auquel un acide aminé prédéterminé est introduit dans chacune des positions d'un ensemble sélectionné de positions dans une zone présélectionnée (ou dans plusieurs zones différentes) d'un polypeptide, en vue de produire une bibliothèque d'analogues de polypeptides. Ce procédé est fondé sur le présupposé que certains acides aminés jouent un rôle crucial dans la structure et la fonction des protéines. On peut ainsi produire des bibliothèques qui contiennent seulement les analogues de polypeptides souhaités et qui sont de taille raisonnable pour permettre un tamisage. Ces bibliothèques peuvent servir à étudier le rôle d'acides aminés spécifiques dans la structure et la fonction de polypeptides et à mettre au point des polypeptides nouveaux ou améliorés, tels que des anticorps, des fragments d'anticorps, des anticorps à chaîne simple, des enzymes et des ligands.

Title: Composite medical device and method of forming
Inventor: WALAK STEVEN E
IPC: A61M39/08
Filed: 2004-12-02
Granted: 2012-09-11
Abstract: Composite medical devices, such as catheters, or the like. In at least some embodiments, composite medical devices, and/or shafts for use therein, that can include a more flexible inner portion and a less flexible outer portion.  In some embodiments, the composite elongate shaft can be constructed by forming a metallic outer portion including a first metallic material about a metallic inner portion including a second metallic material different from the first material. The second metallic material can be more flexible than the first metallic material. A segment of the metallic outer portion can then be removed from the composite shaft to expose a segment of the metallic inner portion. As portions of the outer portion are removed, and/or portions of the inner portion are exposed, certain characteristics along the length of the shaft can be achieved. For example, portions of the shaft can be rendered more flexible by the removal of the outer portion to expose the inner portion.  Additionally, portions of the shaft can be maintained and/or rendered less flexible, or stiffer, by allowing the outer portion to remain thereon. As such, the composite elongate shaft can provide a shaft for a medical device that can include desired characteristics, such as flexibility, torqueability, or the like, along different portions of the shaft.
