Patent CA-2531255-A1 (CA)
Inventor: SCHUMANN MATTHEW A
IPC: G01N37/00
Filed: 1996-01-12
Abstract: A sensor dispensing instrument is adapted to receive a generally circular sensor pack containing a plurality of blood glucose sensors. Each of the sensors are disposed in sensor cavities, each of which is in fluid communication with a corresponding desiccant cavity and has a support wall that assists in directing the sensor as its being ejected from the cavity. The sensor pack is loaded on an indexing disk in the instrument such that when a slide actuator on the instrument is moved toward a testing position, a feed mechanism engaged by the slide actuator moves a knife blade thereon toward one of the sensor cavities. The knife blade pierces a portion of a foil covering the sensor cavity and engages the sensor disposed in the cavity to thereby eject the sensor from the sensor cavity. The continued sliding of the slide actuator toward its testing position results in the sensor being completely ejected from the sensor cavity and disposed in a testing position with a testing end of the sensor projecting from the instrument. Once the blood analyzing test is completed, the slide actuator is moved in the opposite direction towards its standby position. As the slide actuator is moved away from its testing position, the indexing disk with the sensor pack thereon is rotated so that the next one of sensor cavities is positioned so that the sensor therein can be used for the next blood glucose test that is to be performed. The instrument includes circuitry to obtain test data from the sensor pack and to display testing data.

Title: Transparent session migration across servers
Inventor: KALUSKAR SANJAY
IPC: H04L29/06
Filed: 2004-08-13
Abstract: Techniques allow a client to be switched from a session on a server to another session on another server in a way that is a transparent to the application for which the initial session was established. Thus, under transparent session migration, a client is switched between sessions without executing application instructions tailored to accomplish the migration. Instead, a client-side interface component, through which the application interacts with the server, handles details of migration, modifying the internal state of the client-side interface component to effect the same. Legacy applications do not have to be modified in order to institute techniques described herein.

Inventor: CRIVELLI ROCCO
IPC: A61F2/48
Filed: 2006-03-06
Abstract: A telemetry system including a first device having a processor that employs a DC  balanced encoding scheme to generate a DC balanced encoded data signal, a modulator for modulating an RF carrier wave by the DC balanced encoded data signal and generating a DC balanced encoded RF modulated data signal including DC  balanced RF energy. The DC balanced encoded RF modulated data signal transmitted by the first device is received by a second device. Since the RF  energy received is DC balanced, drift in baseline voltage is eliminated irrespective of data transmission thereby improving the robustness of recovery of data by the second device. The second device may include a converter for converting the DC  balanced RF energy extracted from the received DC balanced encoded RF modulated data signal to a substantially constant average induced voltage, irrespective of data being transmitted, for powering at least one component of the second device.

Title: Method and apparatus for monitoring casinos and gaming
Inventor: HUIZINGA RICHARD
IPC: G06Q50/34
Filed: 2000-04-19
Abstract: A system automatically monitors playing and wagering of a game, including the gaming habits of players and the performance of employees. A card deck reader automatically reads a symbol from each card in a deck of cards before a first one of the cards is removed.  The symbol identifies a respective rank and suit of the card. A chip tray reader automatically images the contents of a chip tray, to periodically determine the number and value of chips in the chip tray, and to compare the change in contents of the chip tray to the outcome of game play for verifying that the proper amounts have been paid out and collected. A table monitor automatically images the activity occurring at a gaming table. Periodic comparison of the images identify wagering, as well as the appearance, removal and position of cards and other game objects on the gaming table. A drop box automatically verifies an amount and authenticity of a deposit and reconciles the deposit with a change in the contents of the chip tray. The drop box employs a variety of lighting and resolutions to image selected portions of the deposited item. The system detects prohibited playing and wagering patterns, and determines the win/loss percentage of the players and the dealer, as well as a number of other statistically relevant measures. The measurements provide automated security and real-time accounting. The measurements also provide a basis for automatically allocating complimentary player benefits.

Filed: 2005-01-19
Abstract: Disclosed is method for restoring catalytic activity to a hydroprocessing catalyst that has become spent due to its use or to the deposition of carbon thereon. The method includes a carbon reduction step whereby carbon is removed from the spent hydroprocessing catalyst in a controlled manner to within a specifically defined concentration range. Following the carbon removal step, the resulting catalyst, having a reduced concentration of carbon, is subjected to a chelation treatment whereby the resulting carbon-reduced catalyst is contacted with a chelating agent and aged for a time period necessary for realizing the benefit from the controlled carbon reduction step. In a preferred embodiment, the catalyst resulting from the chelation treatment is subjected to a sulfurization treatment involving the incorporation of elemental sulfur therein and contacting therewith an olefin.

Title: Method and apparatus for characterizing an end-to-end path of a packet-based network
Inventor: NORRIS CHRISTOPHER ROBERT
IPC: H04L12/28
Filed: 2005-02-04
Abstract: The present invention provides a method and apparatus for characterising each segment of the network path between a source host and destination host. The invention comprises collecting data by sending and receiving specific predetermined ordered groups of packets that can vary in size, number and protocol, the packets being sent from the source host and addressed to the destination node. These groups of packets include strategically arranged marker packets and load packets. The load packets typically expire at a predetermined node and the marker packets complete their journey to the destination. After expiry of the load packets, the marker packets provide a means for capturing information enabling the characterisation of each segment up to the expiry of these load packets. Further analysis of the collected information enables adjustement of the characteristics of the groups of packets resulting in an optimisation of the sampling and characterisation of the network path.
