Patent CA-2148934-C (CA)
Title: Targetable vector particles
Inventor: ANDERSON FRENCH W
IPC: C07K14/47
Filed: 1993-11-03
Granted: 2005-08-02
Abstract: A vector particle (e.g., a retroviral vector particle) containing a chimeric envelope includes a receptor binding region that binds to a receptor of a target cell. The receptor of the target cell is other than the amphotropic cell receptor. The receptor binding region may be a receptor binding region of a human virus. A portion of the envelope gene may be deleted and the deleted portion is replaced with another receptor binding region or ligand. Such vector particles are targetable to a desired target cell or tissue, and may be administered directly to the desired target cell or tissue as part of a gene therapy procedure, or administered directly into the patient.

Title: A high-data-rate wireless local-area network
Inventor: CAFARELLA JOHN H
IPC: H04B1/707
Filed: 1995-02-03
Granted: 2003-07-08
Abstract: An apparatus and method for communicating data between at least two data devices, suitable for use as a wireless local-area network, that provides robust data via a radio channel corrupted by multipath interference, particularly at high data rates.  A preferred embodiment of the invention represents data as a sequence of Walsh-function waveforms (66) encoded by pseudo-noise direct-sequence spread-spectrum modulation (70).  Walsh function encoding of the data provides a long symbol duration, thereby allowing the spread spectrum modulation to provide processing gain sufficient to substantially overcome multipath interference, while providing a high data rate.
