Title: Personal passwords management system
Inventor: MEDJITOV TIMUR
IPC: H04L9/32
Filed: 2005-10-14
Abstract: The present invention provides a Personal Passwords Management System: PPMS. PPMS combines a method for the selection of an infinite number of unique and highly secure passwords and a simple and secure method of password retrieval.  PPMS represents a collection of symbols in a form of tables or any other geometrical figures pre-populated with random symbols (a letter, number, or other characters). To select new passwords and later to retrieve created passwords, a user of PPMS first needs to define a password signature and then compare it with the appropriate password table. Password signature is a geometric pattern based on the type of password table used in the PPMS, including its orientation. Thus, by using one or several password signatures a user manages strong, secure passwords for any number of resources.

Patent CA-2545222-A1 (CA)
Title: Signalling method and apparatus
Inventor: ERIC ATHERTON
IPC: E21B47/12
Filed: 2004-11-08
Abstract: An electrical signalling system comprises a modulator arranged to accept information and encode that information in an alternating signal containing repeated rising and falling edges, the encoding being by way of the time between consecutive rising or consecutive falling edges, a transmission path for the signal from modulator to a demodulator, where the demodulator is arranged to detect the signal edge and store a record of the signal around that edge and compare a subsequent part of the signal with that record thereby to detect a like edge and detect the time difference between like edges. Such a system need not detect the precise position of the edge but detects that an edge has occurred within a short time frame, and retains an image of the signal during that period. That image is compared with a subsequent part of the signal, and where the subsequent signal differs only minimally from the record the system deems that a second like edge has occurred. Thus, although the precise position, of the edge may or may not be detected by this system, the time delay between respective like edges is detected. The transmission path can be imperfect, for example inductive. The system is capable of sending recognisable signals along a three-~phase electrical supply cable. The invention is particularly applicable to the supply of information from downhole sensors in the oil and' gas extraction industries. Two signals can be sent simultaneously by also detecting unlike edges and the time difference therebetween. Multiple sources of data can be included consecutively.

Filed: 2004-12-14
Abstract: The invention relates to a method of operating a communication network, the network comprising a plurality of stations which are able to transmit data to and receive data from one another so that a message comprising a plurality of data packets is sent from an originating station to a destination station via at least one opportunistically selected intermediate station. The method makes use of probe signals transmitted from each station on a selected probing channel to which other stations respond to indicate their availability as destination or intermediate stations. A Request to Send message is sent, with a Clear to Send message returned by an available station. The station with data to send opportunistically selects an available station and the selected station uses a Packet Acknowledge message to confirm successful reception of the transmitted data packet. An End-to-End Acknowledge message is sent by the originating station, directly or indirectly, to confirm receipt of said data packets.
