Title: Isolation of stem/progenitor cells from amniotic membrane of umbilical cord
Inventor: PHAN TOAN-THANG
IPC: C12N5/074
Filed: 2005-06-03
Abstract: The present invention relates to a method for isolating stem/progenitor cells from the amniotic membrane of umbilical cord, wherein the method comprises separating the amniotic membrane from the other components of the umbilical cord in vitro, culturing the amniotic membrane tissue under conditions allowing cell proliferation, and isolating the stem/progenitor cells from the tissue cultures. The isolated stem cell cells can have embryonic stem cell-like properties and can be used for various therapeutic purposes. In one embodiment, the invention relates to the isolation and cultivation of stem cells such as epithelial and/or mesenchymal stem/progenitor cells under conditions allowing the cells to undergo mitotic expansion. Furthermore, the invention is directed to a method for the differentiation of the isolated stem/progenitor cells into epithelial and/or mesenchymal cells.
Patent GB-2432766-A (GB)
Title: Communication terminal with echo canceller and its echo canceling method
Inventor: TAKADA MASASHI
IPC: H04B3/23
Filed: 2005-04-07
Abstract: An uncomfortable feeling due to lack of the speech of a speaker at a remote end and a converged signal sound is prevented, and the remote-end speaker echo is removed. A pseudo-circuit has a phase inverter (10) for inverting the phase of a signal, a pseudo-hybrid (11) for creating a pseudo-echo having the same or almost the same characteristic as that of the true echo, and a pseudo-telephone set (5-2). By creating a pseudo-echo having the phase opposite to that of the true echo and having the same or almost the same characteristic as that of the true echo, the true echo is cancelled. When a telephone set is connected to a caller or when an extension transfer occurs, an adaptive filter convergence signal is generated for a predetermined constant time only during "non speech" of the remote end speaker signal.

Title: Securely caching electronic passport data for verification purposes
Inventor: BOND MIKE
IPC: G06F21/32
Filed: 2008-04-29
Abstract: The invention is concerned with securely storing data obtained from an electronic document, in particular data on a smart card system such as those used in ICAO (International Civil Aviation Organisation) compliant EU electronic passports. Data read from an electronic document such as an electronic passport is used to calculate a unique cryptographic key which is then used to encrypt all or part of the data. The encrypted data is stored in a cache and the cryptographic key is discarded. When the electronic document is subsequently presented for verification, the data read from it is used to recalculate the unique cryptographic key and decrypt the encrypted data in the cache. The electronic document may contain biometric data and summary data, the summary data being used to calculate the cryptographic key. The storage of the encrypted data may be under an anonymous identifier whereby the data is not personally identifiable in the cache. The cryptographic key may be a hash value.
