Patent CA-2386108-A1 (CA)
Inventor: MALIK DALE W
IPC: G06Q20/14
Filed: 1999-12-13
Abstract: A telecommuncations system and method for providing access to the Internet on a pre-paid or pay-per-use basis that utilizes an Advanced Intelligent Network ("AIN") to set up a dial up connection between a subscriber and an Internet Service Provider ("ISP"). The telecommunications system communicates with the ISP's computer systems to coordinate verification of callers attempting access to the ISP. The system uses features of the AIN to identify a call as a pre-authorized call so that the ISP grants access without requiring a username and a password from a caller. If the ISP receives a call that is not so identified, the caller is treated as regular ISP subscriber, and requires a username and a password to authenticate the caller prior to granting access to the ISP's resources. The present invention further utilizes the telephone service provider's billing systems to aggregate bills and collect revenue from subscribers. A portion of the revenue is retained by the telephone service provider as a fee for providing the service, and a portion is paid to the ISP  as payment for its services.

Abstract: A system (10) for protecting information over the Internet (16), or other public network, is provided at a web site addressable by one or more client computer systems (18). Each client computer system connects to the web site to receive a respondent identifier and viewer software. A unique viewer identifier is generated by the viewer software at the client computer system  (18) and sent to the web site for registering the viewer identifier with the  respondent identifier. The web site has a database (20) and one or more web servers (12, 13, 14, 15) coupled to the database. The database (20) stores registration information including the viewer identifier and associated respondent identifiers for the client computer systems (18), encrypted conte nt information files and keys to decrypt such files, survey invitation information for each of the surveys, and exposure limit information. In response to receiving a survey in accordance with an invitation, the client computer system (18) enables the content viewer to connect to the web site o f the content protection system (10) and download a file with the encrypted content information for that survey. The viewer software then sends a reques t to the content protection system (10) for a key to decrypt the downloaded content information file. The content protection system (10) determines, bas ed on the respondent, viewer and survey identifiers and associated exposure lim it information, whether to send a decryption key. If so, a decryption key is se nt to the client computer system (18) and the viewer uses the key to decrypt th e encrypted content information file, and then opens a viewer window to show t he decrypted content information on the display of the computer system (18). During viewing on the computer system (18), the viewer limits access to the window showing the displayed content information which would typically allow  the user to access information and enable copying.

Abstract: Cette invention concerne un système efficace d'éclairage vers le bas comprenant une source lumineuse et un dispositif de couplage généralement tubulaire qui présente une surface intérieure réfléchissante destinée à recevoir de la lumière de la source lumineuse par une entrée et à transmettre cette lumière sous forme d'un faisceau généralement divergent par une sortie. Le dispositif de couplage est conformé selon un système optique non imageur et présente une section qui va en augmentant depuis l'entrée jusqu'à la sortie de manière à réduire l'angle de la lumière reflétée par la surface au cours de la traversée du dispositif. Une région thermiquement isolée comporte une entrée disposée à proximité d'une sortie du dispositif de couplage et une sortie pour la transmission de la lumière à un élément optique. Un montage permettant de diviser la lumière à partir de la sortie de la région thermiquement isolée comprend une pluralité de guides de lumière. Chacun de ces guides comprend une extrémité entrée pour la réception de la lumière provenant de la région thermiquement isolée et une extrémité sortie pour l'orientation de la lumière sur un point éloigné. Les extrémités entrée sont situées sensiblement dans le même plan et constituent une forme sensiblement pleine. Le dispositif de couplage et la région thermiquement isolée présentent une forme telle qu'ils peuvent chacun transmettre une dose substantielle (c'est-à-dire utile) de lumière à chacun des guides de lumière. Il est ainsi possible d'atteindre des rendements de quelque 30 lumens par watt.

Title: Claus feed gas hydrocarbon removal
Inventor: DOLAN WILLIAM B
IPC: B01D53/04
Filed: 2001-06-04
Abstract: A process for adsorbing hydrocarbons from an acid gas stream includes passing the acid gas stream through an adsorbent which selectively removes hydrocarbons, desorbing the hydrocarbons from the adsorbent and contacting the desorbed hydrocarbons with an acid gas removal solution to remove acid gases which have been coadsorbed with the hydrocarbons. The process is particularly useful in removing hydrocarbons from a hydrogen sulfide-containing stream which is being directed to Claus processing for conversion into elemental sulfur. Useful adsorbents include crystalline titanium silicate molecular sieves containing titania octahedral sites such as ETS-10 and similar materials, as well as high silica aluminosilicate zeolite.

Inventor: SPEIER PETER
IPC: G01R33/44
Filed: 2002-12-27
Abstract: A method for performing phase encoded inside-out magnetic resonance imaging. The phase of the nuclear spin is advanced by applying a magnetic field gradient between application of each of several refocusing pulse sequences so that echoes are detected during refocusing pulse sequences for different phase advances. The echoes detected for each refocusing sequence are added together and averaged. An image is then generated from the averaged echoes, such as by Fourier transform techniques. In addition, a method is provided for eliminating ringing while measuring a nuclear magnetic resonance property of a volume of earth formation surrounding a borehole. The phase of the refocusing pulses is changed so that pairs of echoes in the echo train have opposite ringing phase. Echoes in the echo train having opposite ringing phase are added to cancel ringing in the echo train.  The echo train can then be analyzed for amplitude and/or decay characteristics.
