Title: Veritas
Inventor: DELINE SHANE MATTHEW
IPC: H04L12/16
Filed: 1999-11-30
Abstract: "a process or system to make Internet purchases safer, through using an 'INTERNET ONLY' CREDIT CARD and cross referencing its number with actual credit card data in order to make a purchase. It is deemed an Internet only card for it can only be used for purchases made over the web and can not be used in stores or for cash advances. The Internet only card, herein called the 'Columbus Card' will consist of randomly assigning a 16 digit number to each 'real' credit card owner who previously held a card with other institutions such as visa or mastercard. Also, this process will only be available to Internet vendors who wish to use this process, herein referred to as the 'Veritas process' for if it is to be successful employed, certain questions must be answered. The user will make a purchase like he/she normally does, and is notified the amount of the total, and given an invoice number. He/she is prompted to write that number down.  When the user is finished and clicks on the button "purchase goods", he/she is then linked to the veritas page, which has the user enter their invoice number and select from a window of options. This can consist of which company he purchased the goods from. A third window will have the user enter their Columbus card number, first name only, address where the goods/service is to be shipped and e-mail address (if applicable). When the user clicks on a button entitled "submit here", the file is sent to the vendor and another to the credit card company. The vendor will not ship the goods unless authorized by the credit card company. Upon receipt of the data, the credit card company will cross reference the user's inputted columbus card number to the the credit company's originally issued columbus card number along with the name to the name held in the database and the user's inputted address to the address held in the data base.  If all three fields match, the actual credit card number is charged, the vendors account credited and the goods are shipped. Also if the user had previously entered a e-mail he or she is notified the purchase has been approved. If any one of the fields does not match the transaction is declined the credit card holder, not the user, is contacted by mail or phone, and notified of the reason why the transaction was declined."

Title: Pollen-based transformation system using solid media
Inventor: BURKE JOHN J
IPC: A01H1/04
Filed: 1998-07-14
Abstract: A medium is disclosed that supports pollen germination and pollen tube growth in the presence of Agrobacterium, the medium comprising agarose, sucrose, NO3, MnSO4, 1-13BO3, MgSO4 and gibberellic acid.  A method is disclosed for the genetic transformation of plants and lines by a pollen-based Agrobacterim-mediated transformation.  The method comprises the steps of obtaining pollen from a first plant, applying a lawn of Agrobacteria to a solid pollen culture medium, the Agrobacterium comprising at least one heterologous gene sequence capable of being transferred to a plant cell, applying the pollen to the solid medium, allowing the pollen to germinate and grow on the medium, whereby the Agrobacterium attaches to the pollen tube or mediates transfer of the heterologous gene sequence to the germinating pollen to obtain transgenic pollen, applying the transgenic pollen to the stigma of a second plant capable of being fertilized by the pollen of the first plant, thereby fertilizing the second plant, obtaining transgenic seed from the second plant and germinating the transgenic seed to obtain a transgenic plant. The method is particularly suited for use with so-called "dry stigma" pollen.
Patent CA-2297961-A1 (CA)
Title: Take-off device for airplanes
Inventor: REINHARD ANDREAS
IPC: B64F1/06
Filed: 1999-05-06
Abstract: The inventive take-off device consists of a telescopic arrangement (7) of, for instance, three pipes (4, 5, 6) arranged in a frame (3) in such a way that it can pivot to a limited extent. The frame (3) is mounted on a horizontal axis (8) that runs through the centre of gravity of the device and, at the most, the centroidal axis (2) of the lift of the airplane wing (1), whereby it can pivot around said axis. The forces that are exerted inbetween the telescopic arrangement (7) and the frame (4) are transmitted via a bushing (9) that is wedged on the outer pipe (4).      A compressed gas accumulator is, for instance, integrated in the innermost pipe (6) and can be opened by means of an actuating pressure signal, whereupon the telescopic arrangement (7) extends outwards. If the device is mounted on a plane, the bottom of the innermost tube (6) knocks against a fixed point on the ground. This allows the plane to accelerate to a lift-off speed. After it has extended outwards, the telescopic arrangement retracts inwards using a compressed gas that is stored in a pressure chamber (11). The compressed gas that escapes via a main discharge valve is deflected to the rear by means of a funnel (10).

Title: A method of surveying a track
Inventor: THEURER JOSEF
IPC: G01B5/20
Filed: 2000-02-11
Abstract: To survey a track (9), a first, mobile measuring vehicle (1) is moved in the direction towards a second, stationary measuring vehicle (2), during which the deviations of the actual track position from a reference line (14) formed by a laser beam are registered. At the start of each measuring cycle, by using a GPS receiver (19), the relative position of the stationary measuring vehicle (2) with reference to a fixedly installed GPS reference station is determined, the said GPS reference station being known within a terrestrial coordinate system and being adjacent to the track section to be surveyed. The reference line (14) is aligned with the mobile measuring vehicle (1) on the basis of the determined position data, and subsequently the track surveying operation is carried out by advancing the mobile measuring vehicle (1).

Title: Method and apparatus for performing service level analysis of communications network performance metrics
Inventor: WHEELER DAVID
IPC: H04Q11/04
Filed: 1998-11-06
Abstract: A data transmission system includes probes (probe A, probe B) connected between end user sites (site A, site B) and a data switching network (12).  Each probe is connected to the switching network (12) via an access channel (20, 21, 26 or 27) wherein transmission circuits establish paths between the sites through the access channel (20, 21, 26 or 27) and switching network (12). The probes capture and retransmit data traveling between the sites over respective transmission circuits, and can thereby insert service level anaylsis (SLA) messages into data traffic in order to actively communicate network performance information to other probes. For each transmission circuit, the probes periodically collect measurements related to one or more network performance metrics, including round-trip delay (RTD), data delivery ratio (DDR) and network availability. During each SLA measurement cycle, a sequence of SLA messages is exchanged over each transmission circuit, which messages contain data used to determine RTD and DDR.
