Title: System and method enabling advertisers to advertise via a system of interactive advertisement images embedded and displayed within advanced television programming and utilized in conjunction with alternate television channel(s)
Inventor: BARRETT BRAD C
IPC: H04N7/16
Filed: 1999-11-26
Abstract: The present invention is a method and system of commerce effectuating the advertising and marketing of consumer product's through a system of advanced television advertising. The system comprises a system wherein interactive advertising images disruptive to the television viewing session are embedded within a television program in a manner whereby embedded image(s) appear within the visual field of a television program when viewed on an advanced television. In order for a viewer to remove the said image(s) from the visual field the viewer is required to interact with the image(s) via a viewer input device (e.g. remote control). Following the said viewer initiated interactive event the program containing the advertising image disappears from the visual field and a short advertising session is displayed during a latency period prior to the television re-tuning to the a television channel that does not contain advertising images. Once the returning process I completed a viewer is then able for a predetermined period of time to view the base television program uninterrupted by advertising images. The system operates via a system where multiple television signals are multiplexed together and transmitted to a viewer location via a communication network.    The first multiplexed signal (Channel A) contains a base television program and embedded interactive advertising image(s), the second signal (Channel B) is encrypted and contains an identical version of the said base television program no advertising images. The third Channel (Channel C) contains an advertising sequence which may be interactive. When a viewer interacts with an image displayed on Channel A decryption and/or location identification code is produced while the television seamlessly re-tunes itself to channel C a short television commercial is displayed before file television re-tunes itself a second time to Channel B. During this procedure the identity of Channel A is stored by the processor and is used to re-tune to Channel A when the Channel B viewing session is terminated. The primary source of income for the system will be from advertiser(s) that utilize the system in order to advertise and market product(s) and/or services(s).

Title: Internet protocol (ip) class-of-service routing technique
Inventor: FISHMAN SAUL DANIEL
IPC: H04L12/56
Filed: 2000-05-18
Abstract: The priority of the flow of packets representing calls or other connection requests within a packet network (10) is determined from the Class-of Service of the call. Upon receipt of a call, a recipient router (12 1, 12 2, 12 3) identifies available paths, typically by exchanging messages with the other routers in the network. After selecting the path, the recipient router or centralized bandwidth broker determines whether the links comprising the selected path have available bandwidth for the class of service of the call. If so, the router routes the call to the next hop along the path. Otherwise, the muter selects another path(s) and checks whether the links on the path possess sufficient bandwidth for the class of service of the call.

Title: Method and apparatus for automatically reducing cross-talk between wires coupled to a common network device
Inventor: ETHIER STEVEN LAURENT
IPC: H04L12/46
Filed: 1999-04-30
Abstract: A method of adjusting the sensitivity of a receiver requires the association of a network address of a remote network device (16), such as a computer, with a first port (62) of a multiport network device (60), such as a switch. The reception of the network address of the remote network device at a second port of the multiport network device indicates the possible occurrence of a cross-talk condition between networks coupled to the first and second ports.  Accordingly, the sensitivity of a receiver associated with the second port is reduced in an attempt to reduce the sensitivity thereof to a point at which cross-talk signals, generated as a result of the cross-talk condition between networks coupled to the first and second ports, are no longer detected. The sensitivity of the receiver may be reduced by increasing a noise threshold level below which signals are not detected.

Title: Nanoelectrode arrays
Inventor: PEETERS JOHN P
IPC: C12Q1/68
Filed: 1998-11-04
Abstract: An array of electrodes (26a, 26b, and 26c) at the atomic or nano scale (nanoelectrodes) is built on a chip (22). The spatial distribution, height, width and electro-chemical composition of the nanoelectrodes is varied, such that protein-specific electronic receptors are built directly on the chip with the nanoelectrodes without the use of any specific binding agents or molecules. Because of their size, a very large number of different receptors can be built as arrays on a single chip. The chip can be used to detect, characterize and quantify single molecules in solution such as individual proteins, complex protein mixtures, DNA or other molecules.

Patent CA-2324282-A1 (CA)
Inventor: KENKNIGHT BRUCE H
IPC: A61N1/39
Filed: 1999-03-19
Abstract: A system for defibrillating an atrial region of a heart experiencing a supraventricular arrhythmia. The defibrillation system senses and analyzes both atrial and ventricular cardiac signals of the heart to determine if the heart is experiencing a supraventricular arrhythmia. Upon detecting a supraventricular arrhythmia, the defibrillation system begins delivering a train of atrial pacing pulses to the atria of the heart and a series of ventricular pacing pulses to the ventricles of the heart to synchronize the contractions of the heart with the pacing pulses. The defibrillation system then delivers a defibrillation electrical energy pulse across the atrial region at a predetermined coupling interval time after delivering a final atrial pacing pulse and a final ventricular pacing pulse so that the defibrillation pulse will fall outside the occurrence of a T-wave of the heart, thus reducing the likelihood of inducing ventricular fibrillation.

Abstract: A method for detecting fault attacks against cryptographic algorithms comprising an initialisation process to which an init vector and a key are supplied to compute at least one sub-key from the key; a checksum function on the at least one sub-key and the init vector. The result of the checksum computing step is stored. The method also includes, in the cryptographic algorithm to which are supplied a message, an init vector and a key, computing at least one sub-key from the key; computing a checksum function on the at least one sub-key and the init vector; comparing the result of said checksum computing step with said stored result; and encrypting the message via an encrypting algorithm using the computed sub-keys. Wherein a fault attack is detected when the result of the comparing step is that the stored result of the checksum computing step of the initialisation process is not identical to the result of the checksum computing step of the cryptographic algorithm.
