Patent CA-2319288-A1 (CA)
Inventor: ROSEMAN MORTON F
IPC: G07D7/04
Filed: 2000-09-14
Abstract: The authenticity of an item which is one of a group of such items can be determined by attaching to or incorporating into each such item an authentication marker, all such markers interacting substantially identically with a given magnetic field. A field generating apparatus is provided which incorporates a reference sample that interacts with the given magnetic field in the same way as the authentication markers do. The field generating apparatus subjects both the reference sample and a candidate authentication marker to substantially identical magnetic search fields. A receiver apparatus detects the signals resulting from the interactions of the reference sample and the candidate marker with their respective magnetic search fields, so that, with the candidate marker positioned at a predetermined location with respect to the field-generating apparatus, substantially identical magnetic fields can be generated around the reference sample and the candidate marker, whereupon the receiver apparatus detects the signals.  Comparing means are provided for comparing the signals to determine the authenticity of the candidate marker. In a preferred form, the field-generating apparatus and the receiver apparatus both include portions of an H-shaped ferromagnetic core. The field generating apparatus includes a coil encircling the cross bar of the H, while the receiver apparatus includes first and second receiver coils respectively encircling opposite ends of one of the upright bars of the H. The receiver coils are wired in series such that their signals cancel if the reference sample is identical to the candidate authentication marker.

Title: Tar sands extraction process
Inventor: HUMPHREYS REGINALD D
IPC: B01D17/00
Filed: 2000-11-06
Abstract: A hot water extraction process for extracting bitumen from tar sands is taught using a conditioning agent containing sodium sesquicarbonate. The conditioning agent replaces the caustic soda agent previously used in tar sand extraction.

The method comprises steps of providing a calculation scale look up interface, a range look up result interface, a multiplication product of the results returned by the two interfaces, an apportioned monetary value for each of the commerce objects. The method is particularly useful in implementations for determining weighted shipping charges, discounts and taxes in various commercial environments. The environments may include a variety of calculation rules based on the circumstances in the commercial environment. The invention also provides a computer product for implementing the various methods. The computer product includes a recording medium such as a magnetic floppy disk, CD-ROM, hard drive or other suitable means. The products and methods are particularly useful in association with web-based commercial software applications. The methods and products provide a calculation scale framework which may be reused to avoid programming changes despite frequent, and often significant, changes in commercial environments.

Patent CA-2331236-A1 (CA)
Title: Conferencing and announcement generation for wireless voip and voatm calls
Inventor: STROM KENNETH WAYNE
IPC: H04M3/00
Filed: 2001-01-17
Abstract: A telecommunication system routes wireless-specific digital frames from a first wireless communication device across a data-oriented network, without vocoding, for information delivery to a second communication device while implementing multi-party conferencing and tone/announcement generating functionality. Tone and announcement generation services are provided while the call path retains the wireless-specific digital frame format between the first wireless communication device and the terminating gateway. When tones are generated by the first wireless communication device, signaling messages are sent directly to the terminating gateway vocoder to initiate the generation of full rate DTMF tones at the terminating network. When tones and announcements are sent to the first wireless communication device, a resource server, working together with a feature server, generates a wireless-encoded version of the tone or announcement. This wireless-encoded version is then sent to the first wireless communication device, where an audible version of the tone or announcement is produced. When multi-party conferencing is initiated, the first call is established via wireless-specific digital frame communication. The first call is placed on hold while the second call is completed using a digital wireline format (e.g., PCM). Through vocoding, the first call's connection is re-negotiated to match the digital wireline format of the second call. To complete the conference call, the two calls are combined in the conference circuit as a composite digital wireline traffic stream.
