Inventor: RAJI FAIBA
IPC: H04Q7/38
Filed: 2003-06-17
Abstract: A method transmits data packets in a mobile radio system and corresponding mobile radio system. The method permits an immediate transmission of data packets to the receiver station along a new transmission path, after a handover of a connection along a transmission path, between a transmission station and a receiver station, to a new transmitting station.

Patent CA-2475936-A1 (CA)
Title: Linear motor
Inventor: DUNCAN GERALD DAVID
IPC: F04B17/04
Filed: 2000-06-21
Abstract: The present invention provides an improved design of linear motor as well as an improved control strategy. The design allows for a shorted stator, where the armature magnets are controlled to reciprocate to a greater maximum displacement than for an equivalent conventional linear motor. The control strategy is such that a minimum of external sensors are required. The linear motor is driven at its resonant frequency ensuring optionally efficient operation. A determination of the maximum current is made based on a relationship with the resonant frequency and the evaporating temperature/pressure of the vapour entering the compressor. The current is then limited to control the maximum displacement to avoid damage.

Title: Identifying peptide modifications
Inventor: MAROTO FERNANDO M
IPC: G16B30/00
Filed: 2003-03-11
Abstract: Methods, systems and apparatus implement techniques for identifying modifications in polypeptides. A set of candidate sequences is identified that includes sequence information potentially corresponding to an unmodified variant of the polypeptide. Peptides derived from the polypeptide are sequenced to identify sequence tags. The sequence tags are compared with sequence information for the set of candidate sequences to identify a candidate sequence containing the sequence tags. For each such sequence tag, the difference between at least one subsequence mass of the corresponding peptide and at least one subsequence mass of the identified candidate sequence is calculated. The candidate sequences containing the sequence tags can be identified by searching a reduced database constructed based on the identified set of candidate sequences.

Title: Short chain polymer for enhancing the bioadhesiveness of polymers on mucosal membrane
Inventor: SANTOS CAMILLA A
IPC: A61K47/34
Filed: 2003-05-15
Abstract: Methods and compositions are provided for enhancing the bioadhesive properti es of polymers used in drug delivery systems. The bioadhesive properties of a base polymer are enhanced by incorporating a short chain polymer with one or more free carboxylic groups into the base polymer to enhance the ability of the base polymer to adhere to a tissue surface such as a mucosal membrane. T he short chain polymers can be incorporated within a wide range of base polymer s including proteins, polysaccharides and synthetic biocompatible polymers. In one embodiment, short chain polymers can be incorporated within base polymer s used to form or coat drug delivery systems, such as microspheres, which contain a drug or diagnostic agent. The short chain polymers can either be solubilized and blended with the base polymer before manufacture or else use d as a coating with base polymers over existing systems. The base polymers, fo r example in the form of microspheres, have improved ability to adhere to mucosal membranes, and thus can be used to deliver a drug or diagnostic agen t via any of a range of mucosal membrane surfaces including those of the gastrointestinal, respiratory, excretory and reproductive tracts.

Title: A method and system for recovering password protected private data via a communication network without exposing the private data
Inventor: BACK ADAM
IPC: H04L29/06
Filed: 2005-04-01
Abstract: A system and method for securely roaming private data from a first client computer to a second client computer linked via a communication network. A  user of the first client computer executes a home client application and designates private data for roaming. The home client application generates a first key in response to a password, and encrypts the designated private data as a function of the first key. The server receives and stores the encrypted private data. A user of the second computer executes a roaming client application and requests transfer of the encrypted private data from the server. The roaming client application generates the first key in response to the password, and decrypts encrypted private data transferred from the server to obtain the private data. The invention further provides users the ability to retrieve encrypted private from the server even when the user cannot remember the password associated with the first key. Also, the server has no knowledge of the private data nor the keys.
