Patent CA-2330958-A1 (CA)
Inventor: HAVERTY RAND
IPC: G06F21/31
Filed: 1999-05-06
Abstract: A method, computer system, and program product provides for authentication o f user messages using PKI technology in environments where limited capacity prevents direct PKI technology use, and strong security is provided using magnetic swipe cards or the like, and a passphrase is used for enhanced security and to avoid the need for special purpose devices. The invention is  advantageous where there are limitations on the space available for PKI credentials, such as in the userid and password fields of a remote access protocol. PKI techniques are used without transferring lengthy keys or certificates once an initial registration process is complete. A secret key is used. A digest is computed of the secret key, the user's certificate serial number, and a time stamp. The digest, together with the user's certificate serial number and the time stamp, forms a compact message that may be transmitted. Private keys and secret keys are not sent during authentication . Replay attacks are prevented.

Patent CA-2337737-A1 (CA)
Inventor: GINESI ALBERTO
IPC: H04L27/26
Filed: 2001-02-22
Abstract: For several reasons some current G.992.1 and G.992.2 modems implement the transmitter (either the U/S or the D/S) with an IFFT size greater than the one specified by the Standard. If the images of the transmit signal are correctly replicated with period equal to the clock frequency of the Standard IFFTs (276 kHz for U/S and 2208 kHz for D/S), no difference is of course observed as the in this case the transmit signal is exactly the same as the one generated by a Standard-size IFFT. However, this does not occur in some of the G.992.x modems. Even though this does not compromise interoperability, if the receiver is not made aware of the way the transmit signal is generated inter-performance may be affected, particularly on short loops.

Abstract: A cover plate for a concealed sprinkler includes a member having at least one passageway section enabling heated air to pass between the cover plate and the sprinkler housing and towards the sprinkler head to permit the timely activation of the sprinkler head. In one preferred form, the passageway section is defined by at least one lip projecting from the periphery of the cover plate, away from the sprinkler head. Alternatively, the cover plate may include a peripheral rim projecting away from the sprinkler head. In another preferred embodiment, the passageway section is defined by one or more undulations formed within the cover plate, each of which define a ridge at the periphery, enabling air to pass therethrough. The cover plate is substantially planar and includes a plurality of mounting tabs upon which a fusible material is applied to adhere the cover plate to the housing of the sprinkler head. The cover plate of the present invention increases the response time of the concealed sprinkler head while maintaining a low profile, discrete appearance so as not to detract from the sidewall or other structure upon which it is supported.

Title: Method and arrangement for measuring and predicting of radio conditions in a communications system
Inventor: HALVARSSON MATS
IPC: H04B7/26
Filed: 1999-10-01
Abstract: In a mobile telecommunication system the transmission quality is dependent on a wide range of radio conditions. The method solves the problem associated with extracting a useful estimation of the radio environment of a mobile station in communication in order to predict how the radio conditions will change for the considered mobile station in the near future. A measurement report (210) is sent from the mobile station to its serving base station. The quality measured in the measurement report is filtered over the area by a smoothing filter (220), and then processed through an updating filter (230) resulting in a time varying map (240). Several maps are classified (260). Classified data are grouped (270) resulting in the final map, which is stored in a database (280). The final map may be used to enhance the performance of radio network algorithms.

Abstract: A small sized shallow pouch like container (3) for a dispensible ingredient (2A, 2B) includes a pair of built-in outwardly pivotable flaps (5, 6) positioned on opposite sides of the container'soutlet end to form a package applicator (1). Squeezing the container's sides (16, 18) with the fingers expresses the stored ingredient (2A, 2B) through the outlet and onto the applicator flaps (5, 6). Using the container (3) portion as a finger grip, the flaps (5, 6) may be moved about the desired surface, spreading the dispensed ingredient (2A, 2B). In some embodiments the outlet is opened by squeezing the container sides (16, 18) to break a closure seal (19). In others the outlet is unsealed by pulling the flaps (5, 6) apart (19'); by tearing (35) or is unblocked (57) by unfolding the flaps (5, 6). In a preferred embodiment the container (3) and applicator (1) combination is formed by a pair of flexible foil sheets (21, 22) of substantially identical structure that are superimposed over one another and partially connected together to define both the container (3) and the applicator (1).

Title: Non-myeloablative tolerogenic treatment
Inventor: SLAVIN SHIMON
IPC: A61K35/28
Filed: 1999-12-23
Abstract: The present invention features a method of inducing bilateral transplantatio n tolerance; host specific tolerance of the graft is especially considered. Tolerogenic treatments of the present invention may be administered to a hos t prior to transplantation of donor-derived materials. The tolerogenic treatme nt involves (1) administering an immunosuppressive agent to a host mammal in a non-myeloablative regimen sufficient to decrease, but not necessarily to eliminate, the host mammal's functional T lymphocyte population; (2) infusin g donor antigens from a non-syngeneic donor into the host mammal; (3) eliminating those host T lymphocytes responding to the infused donor antigen s using a non-myeloablative dose of lymphocytotoxic or tolerizing agent; and ( 4) administering donor hematopoietic cells to the host mammal. Donor lymphoid cells used for cell therapy of a host mammal can be depleted of host specifi c immunological reactivity by methods essentially similar to those used for tolerizing a host mammal prior to transplantation.

Abstract: A computer input device sterilization apparatus having ultraviolet sterilization in an enclosed container to kill bacteria and other disease carrying organisms. The invention comprises a horizontal or vertical container dimensioned to fit over computer input devices such as keyboards, mice, trackballs touchpads and the like. An ultraviolet source within the container irradiates the computer input device with UV light which, in one embodiment generates ozone gas, thereby killing any microorganisms that might reside on the computer input devices. Ultraviolet radiation below 200 nm can also be used thereby creating ozone gas having germicidal characteristics. The ozone gas is circulated in and around the input device thereby providing further sterilization together with the ultraviolet radiation. A sterilization switch turns the UV source off when the container is opened. A timer/power circuit provides the times application of power to the UV lamps to provide UV illumination consistent with the substantial sterilization of the input device in question.

IPC: G06F17/30
Filed: 2000-02-17
Abstract: A method and mechanism are provided for creating. maintaining, and using a hierarchical index to efficiently access information in a relational system based on pathnames, thus emulating a hierarchically organized system. Each item that has any children in the emulated hierarchical system has an index entry in the index.  The index entries in the index are linked together in a way that reflects the hierarchical relationship between the items associated with the index entries. Pathname resolution is performed by following direct links between the index entries associated with the its in a pathname, according to the sequence of the filenames within the pathname. By using an index whose index entries are linked in this manner, the process of accessing the items based on their pathnames is significantly accelerated, and the number of disk accesses performed during that process is significantly reduced.
