Patent CA-2244569-A1 (CA)
Title: Technique for limiting network congestion
Inventor: ODLYZKO ANDREW M
IPC: H04L12/24
Filed: 1998-08-07
Abstract: A technique for regulation of packet switched network traffic through usage-sensitive pricing is disclosed. The network is partitioned into logical channels and a user incurs a cost for use of each of the logical channels.  The logical channels differ primarily with respect to the cost to the user. Each user will select a channel that provides the subjectively optimal balance of cost and perceived quality of service, with the lowest cost channels presumably carrying the most traffic (and hence being more congested) and the highest cost channel accordingly carrying the least traffic (and hence being the least congested). Network traffic will accordingly be distributed between channels and each user will incur predictable charges without being precluded from seeking a higher quality of service when desired.

Title: Band converted cellular communication systems and methods
Inventor: PRZELOMIEC THOMAS A
IPC: H04W16/14
Filed: 1997-03-12
Abstract: The present invention provides techniques for adapting the portion of the frequency spectrum allocated to Land Mobile Radio (LMR) for use as downbanded cellular channels. These downbanded cellular channels can be employed, for example, either to supplement a cellular operator's system capacity or as a stand alone cellular-style system which can provide complementary geographic coverage which may, for example, bridge existing cellular systems. According to a first aspect of the present invention, the conventional channelization of the LMR spectrum is redefined in a manner which provides significant advantages. More specifically, for every six originally specified, 25 KHz LMR  channels, five new 30 KHz DBC channels are specified. In this way, complete compatibility with cellular systems, e.g., allowing roaming between cellular and DBC systems, is achieved according to the present invention.

Patent CA-2256747-A1 (CA)
Inventor: KRAKOWIAK KRZYSZTOF E
IPC: B01D15/00
Filed: 1997-07-07
Abstract: A method for the colorimetric quantification of a targeted ion from a source solution, which may contain other ions in greater concentrations, comprises bringing a measured volume of the source solution into contact with a porous web or membrane having enmeshed therein an ion recognition substrate which has a selective affinity for the targeted ion. The ion recognition substrate selectively and quantitatively traps the targeted ion, for example, through covalent, or ionic bonds, chelation, complexation or organo-metal dative bonds. Following removal of the source solution, the concentration of the targeted ion in the original solution, may be detected and quantified by, for example, visual comparison or densitometric techniques. The ions which are trapped in the web or membrane can be (a) self-colored through interaction with the ion recognition substrate or (b) subjected to a second solution whicn contains a developer. The developer, which may be colorless or of a different color, is chosen because it will selectively react with the targeted ion or, because of the presence of the targeted ion, cause the formation of a colored or color changed product. The density of the color can be correlated to the concentration of the targeted ion in the measured source solution.
