Title: User assisted wireless fraud detection
Inventor: OWENS LESLIE DALE
IPC: H04L9/32
Filed: 1998-04-27
Abstract: A method for detecting fraud in a wireless communication system. During a first access to the system using a subscriber account, the system stores data identifying the first access in a database. During a second subsequent access to the system using the same subscriber account, the system retrieves the stored data identifying the first access and transmits at least a portion of the retrieved data to the wireless device used for the second access. The user of the device reviews the data, determines whether the first access was authorized, and sends a response to the system indicative of whether the first access was fraudulent. If the response indicates that the first access may have been fraudulent, the wireless service provider may take appropriate action.

Filed: 1997-01-13
Abstract: A cellular immunogen is provided for immunizing a host against the effects of the product of a target proto-oncogene, where the overexpression of the target proto-oncogene is associated with a malignancy. The cellular immunogen comprises host cells which have been transfected with at least one transgene construct comprising a transgene cognate to the target proto-oncogene and a strong promoter to drive the expression of the transgene in the transfected cells. The transgene encodes a gene product which induces host immunoreactivity to host self-determinants of the product of the target protooncogene gene. The transgene may comprise, for example, wild-type or mutant retroviral oncogene DNA cognate to the target proto-oncogene; or wild-type or mutant proto-oncogene DNA of a species different from the host species. The cellular immunogen may be prepared from biopsied host cells, e.g. skin fibroblasts, which are stably or transiently transfected with the transgene construct containing the cognate transgene. The host cells transfected with the cognate transgene construct, are then returned to the body of the host to obtain expression of the cognate transgene in the host.

Title: Process of supplying moisture at small flow rate
Inventor: MORIMOTO AKIHIRO
IPC: C01B5/00
Filed: 1998-12-09
Abstract: A process of supplying moisture at small flow rates which permits control with high precision of the flow of moisture to a semiconductor manufacturing line from an apparatus for generation of moisture, characterized in that the flow of hydrogen to a moisture generating reactor is controlled by means of a flow controller in such a way that an amount of hydrogen as fed is gradually increased from the start and reaches a specific set level such that when a specific time has passed, a predetermined rate of moisture begins to be produced and supplied to the semiconductor manufacturing line.          The moisture is generated in the apparatus for generation of moisture in which  hydrogen and oxygen are fed into a reactor provided with a platinum coat on the wall in the interior space, enhanced in reactivity by the platinum catalytic action and caused to instantaneously react with each other at a temperature lower than the ignition point to produce a moisture without undergoing combustion at a high temperature.

Abstract: Apparatus and method of conducting data sessions between a plurality of first sites (customer premises) and a plurality of second sites (servers) primarily for the purpose of retrieving stored data relating to one or more monitored devices (such as a power meter, gas meter, or water meter) are described. A  remote monitor at each first site is provided with a CID capable modem. The remote monitor interposes itself between the communications medium (e.g., telephone network) and customer premises communications equipment (e.g., telephones) and intercepts data phone calls intended for reading the monitored devices. The remote monitor selectively connects and disconnects the customer premises communications equipment (telephones) and manages the state of the data phone calls so that its operation is invisible to the user of the communications equipment (telephone). Incoming data calls are validated and identified by matching incoming caller ID (CID) data with pre-stored, authorized server telephone numbers.

Filed: 1999-01-25
Abstract: A method provides for improved compression techniques over inherently unreliable underlying networks. A fixed compression dictionary is sent from a first terminal to a second terminal during the start up of a communications session between the terminals. The first terminal then compresses data in accordance with the transmitted fixed dictionary. The receiving terminal expands the compressed data in accordance with the received fixed dictionary. If packets are lost over the network such loss does not have a deleterious effect on the compression algorithm as in known adaptive compression techniques.

Title: Multi-frame synchronization for parallel channel transmissions
Inventor: BAKHUIZEN MARTIN
IPC: H04L29/00
Filed: 1997-10-31
Abstract: The present invention comprises a method and apparatus for synchronizing data frames (110) from a wide bandwidth data stream (100) which is divided up and transmitted across a plurality of parallel channels (170A-P) in a mobile telephone system. Prior to transmitting the data frames (110), a transmit synchronizer (120) synchronizes data frames (110) aligned in the same position in different parallel channels (170A-P) by inserting a common bit (160) from a repeating PN synchronization sequence (150) into the aligned data frames (110). Upon receiving the data frames (110) at a destination, a receive synchronizer (145) extracts the synchronization bit (160) from each data frame (110). A series of sequential bits (155) from each parallel channel is compared against the original PN synchronization sequence (150) to identify the position of each data frame (110) relative to the other data frames (110) and reconstructs the original wide bandwidth data stream (100).

Inventor: CULLIS PIETER R
IPC: A61K9/66
Filed: 1999-05-13
Abstract: Treatment or prevention of a disease characterized by aberrant expression of a gene in a mammalian subject is achieved using lipid-encapsulated therapeutic nucleic acid particles made from a therapeutic nucleic acid component that hybridizes specifically with the aberrantly expressed gene to reduce its expression in the subject encapsulated within a lipid particle. The lipid particle is formed from a lipid mixture including a steric-barrier lipid component selected from among lipids that prevent particle aggregation during lipid-nucleic acid particle formation and which exchange out of the lipid particle at a rate greater than PEG-CerC20, and is administered in a therapeutically effective or prophylactic amount to the mammalian subject in a plurality of separate doses separated in time by intervals of up to eight weeks. The particles are preferably formulated using a PEG-modified or polyamide oligomer-modified lipid as the first lipid component. To achieve high loading levels, an effective method for preparation of the lipid-encapsulated nucleic acid particles involves the use of a lipid mixture comprising at least the first lipid component and a protonatable lipid component selected from among lipids containing a protonatable group that has a pKa such that the lipid is in a cationic form at a pH below the pKa and a neutral form at around physiological pH. The method the invention is particularly useful for therapy using lipid-encapsulated antisense nucleic acids or ribozymes. In a more general sense, however, the method of the invention may also be used for delivery of non-cytotoxic lipid-encapsulated therapeutic agents generally in a repeat dosing regimen.
