Filed:

Apr 24, 2002

Appl. No.:

10/132085

Inventors:

Andrew A. Gray - Pasadena CA, US

Assignee:

California Institute of Technology - Pasadena CA

International Classification:

G06F 17/10

US Classification:

708300, 708321

Abstract:

Disclosed is a method of providing signal processing operations, including convolution/filtering, where each parallel stream is processing signals at a lower rate than the signal data rate itself while still resulting in an overall signal processing rate suitable for high rate signal processing. This allows devices with a lower signal processing rate to be used in the parallel processing paths, avoiding many of the problems facing prior art high data rate signal processing. The invention converts a signal from the time domain to the frequency domain and takes advantage of associative and communicative properties of data processing to perform signal processing operations in parallel.

US Classification:

3703955, 370469, 709221

Abstract:

A reconfigurable architecture for wireless digital data and voice communications is provided for ad hoc and/or an ad hoc collection of organized networks. At least some user wireless communication units serve as relay stations for other users units, enabling any user within the range of another, participating user to gain access to the local- and wider-area networks in a multihop process. Reconfigurable hardware enables dynamic protocol “preferencing”, and easy upgrades to potential future wireless protocol standards. Power-efficient communication takes place by using multihop radio communication at the local level and high-speed point-to-point links (e. g. fiber, satellite) at the global level. Microcells within a network community are aggregated into cells by use of a local-area-network (LAN) backbone of higher speed wireless and/or wired connections. Every time a microcell connects to the wireless backbone, microcells or individual users in surrounding blocks can also connect to the network.

International Classification:

B01D 35/06

US Classification:

210222, 209 29, 209213, 209214, 210 94, 210695

Abstract:

Apparatus and method for manipulating particles on a micro- or nano-scale. An embodiment of the present invention includes a magnetic micro-manipulation technique that utilizes micro-coils and soft magnetic microscopic wires for localized manipulation of particles. Another embodiment of the present invention uses magneto-static interaction between two magnetic microscopic wires to mechanically manipulate particles. Yet another embodiment of the present invention combines a magnetic particle with a magnetic manipulator or other device for generating magnetic fields to operate as a micro-fluidic micro-motor. Other embodiments of the present invention employ a magnetic separation system employing porous membranes partially filled with magnetic wires.

Abstract:

A liposome composition that is useful for treating a subject in need of cancer treatment includes a cross-linked multilamellar liposome having an exterior surface and an interior surface. The interior surface defines a central liposomal cavity. The multilamellar liposome includes at least a first lipid bilayer and a second lipid bilayer. The first lipid bilayer is covalently bonded to the second lipid bilayer. At least one anticancer compound is disposed within the multilamellar liposome. Methods for treating subjects are also provided.
