Title: Mecanismo de retroalimentacion de posicion para unimplemento.
Inventor: FOX ROBERT EUGENE
IPC: A01B63/00
Filed: 1993-12-09
Abstract: Un mecanismo de retroalimentación para proporcionar una señal de posición de implemento incluye un potenciómetro giratorio montado sobre el armazón de implemento a un lado del eje oscilante con el eje de la flecha de potenciómetro extendiéndose en paralelo al eje oscilante. Una estructura de articulación incluye un brazo de potenciómetro conectado a un brazo de eje oscilante mediante una articulación de manera que el ángulo que forma el brazo de potenciómetro con la articulación es agudo que forma el brazo de potenciómetro con la articulación es agudo cuando el implemento está en la posición de transporte y es obtuso cuando el implemento está en el rango de trabajo de campo descendido. En la posición más baja del implemento, la articulación y el brazo de potenciómetro se acercan a una posición sobre el centro. KA estructura de articulación proporciona una rotación amplificada del eje de potenciómetro en relación al eje oscilante cuando el implemento está en el rango de trabajo de campo de las posiciones, mientras que la rotación del eje se reduce en relación a la rotación del eje oscilante cuando el implemento es levantado a arriba de la posición de trabajo de campo. En la modalidad preferida, la rotación del eje oscilante 10° en el rango de trabajo de campo resulta en la rotación de sobre 30° del eje de potenciómetro. La rotación del eje oscilante de 10° en el rango superior de las posiciones de transporte elevadas resulta en menos de alrededor de 8° de una  rotación de eje de potenciómetro. La rotación amplificada en el rango de trabajo de campo aumenta significativamente la exactitud y la repetitividad de la señal de retroalimentación.

Title: Inhibition of protease activity of human whole blood cell lysates.
Inventor: OH SE-KYUNG
IPC: G01N33/53
Filed: 1995-03-09
Abstract: A method of inhibiting proteolytic degradation of a thermally-stable intracellular protein is described. The method involves adding 1 or more denaturing agents to a sample which contains the protease and the protein of interest and heating the resulting solution at a temperature and for period of time sufficient to denature the protease. The method optionally includes a step for lysing the cell if the protein of interest is contained in a cell in order to release said protein. Additionally, a method of determining Mx protein induced by interferon in a blood sample is described. The method involves adding to a blood sample a lysing agent, a denaturing agent, and a detergent selected to solubilize Mx protein. The sample containing Mx protein is then heated at a temperature of from about 50 degree C to about 60 degree C for a period of time of from about 1 minute to about 30 minutes, and the Mx protein in the solution then is determined. Also described is a solution including a synthetic matrix mimicking whole blood cell lysates, or actual whole blood cell lysates, to which a known concentration of a thermally-stable intracellular protein is added to prepare a control material. In addition, a solution free of a protease that degrades the intracellular protein is disclosed, such solution remaining stable at 4 degree C for at least three weeks.

Title: Automated drive-up vending facility.
Inventor: RIVALTO MICHAEL A
IPC: G06Q20/18
Filed: 1997-08-12
Abstract: An automated drive-up vending facility (10) and method utilizes a plurality of automatic transaction machines (12) located around the periphery of a storage building (14), whereby customers can drive their vehicles alongside the building, insert an account/debit card into a card reader (16), and make product selections via a touch screen display terminal (18). The products are stocked within building (14), and an automated picking/sorting subsystem (20) retrieves the selected products for deposit into a dispensing chute (22). Selection and product information is provided at the display terminals (18) via an interactive menu driven program. Selection of products subject to sales restrictions automatically activates video conferencing equipment (26) so that a sales attendant can confirm customer authorization to purchase the selected product. Customer purchasing history is stored and analysed to improve a product's chances of promotional marketing influencing a customer's product selection prior to the completion of a vending transaction.

Title: A method for determining the load induced by a routing verification test on a network.
Inventor: GLITHO ROCH
IPC: H04Q3/00
Filed: 1996-02-27
Abstract: There is disclosed a method for determining the load to be induced on a network (10) by running a routing verification test ont the network. The method involves utilizing the telecommunications management network (51) to sample through a general purpose management interface routing table information at live nodes (12-22) in the operating network (10). The telecommunications management network (51) subsequently determines the message tree between an operator selected source node (12) and destination node (22) and determines from this tree the number of transmitted, acknowledged and received messages that would be generated by conducting a routing verification test on the network (10). This method has the advantage that the operator is informed before running a verification test of the load that test will induce on the network (10). Thus the operator can run the test at his discretion to ensure that overload conditions are not experienced by running the test.

Title: System and method for inserting static and dynamic images into a live video broadcast.
Inventor: DICICCO DARRELL S
IPC: H04N5/272
Filed: 1997-12-16
Abstract: A live video insertion system efficiently places static (186) or dynamic images into a live broadcast. The system initially identifies natural landmarks within the video scene that can be automatically identified and tracked as the field of view of the camera pans and zooms across the scene. The locations of the landmarks are mathematically modeled and stored as a constellation of locations on a mathematical grid. An arbitrary reference point, preferably not necessarily coincident with a selected natural landmark, is located within or without the grid and used as an origin for the purpose of inserting the static (186) or dynamic image within the field of view of the camera. For static images, it is frequently desirable to place an edge or border of the image to be inserted on the reference point. For dynamic insertions, the distance between the reference point and the inserted dynamic image is automatically changed from frame to frame in order to make the image appear as though it's translating or changing, or both.
