US Patent:

20210047178, Feb 18, 2021

Filed:

Sep 29, 2020

Appl. No.:

17/035844

Inventors:

- Ottawa, CA
Jeremy Barton - Ottawa, CA
Aru Hill - San Jose CA, US
Michael Drew - Union City CA, US
Damian Allis - Syracuse NY, US
Tait Takatani - Plano TX, US
Michael Shawn Marshall - Liburn GA, US
Matthew Kennedy - Tucker GA, US

International Classification:

B82B 3/00
G01Q 70/14

Abstract:

Methods, systems, and devices are disclosed for performing mechanosynthesis, including those that involve bulk chemical preparation of tips, multiple tips for supplying feedstock, and use of sequential tips such as in a thermodynamic cascade; such features may simplify starting requirements, increase versatility, and/or reduce complexity in the mechanosynthesis equipment and/or process.

Appl. No.:

16/385692

Inventors:

- Ottawa, CA
Jeremy Barton - Ottawa, CA
Michael Drew - Union City CA, US
Robert A. Freitas - Pilot Hill CA, US
Aru Hill - San Jose CA, US
Matthew Robert Kennedy - Tucker GA, US
Ralph C. Merkle - Santa Clara CA, US

Michael Shawn Marshall - Lilburn GA, US

International Classification:

G01Q 80/00
C01B 32/28
C01B 32/26
B82B 3/00

Abstract:

Build sequences for fabricating an atomically-precise product can be determined using computational chemistry algorithms to simulate mechanosynthetic reactions, and which may use the mechanosynthesis process conditions or equipment limitations in these simulations, to determine a set of mechanosynthetic reactions that will build an atomically-precise workpiece with a desired degree of reliability. Methods for error correction of pathological reactions or avoidance of pathological reactions are disclosed. Libraries of reactions may be used to reduce simulation requirements.

Appl. No.:

16/325241

Inventors:

- Ottawa, CA
Jeremy Barton - Ottawa, CA
Aru Hill - San Jose CA, US
Michael Drew - Union City CA, US
Damian Allis - Syracuse NY, US
Tait Takatani - Plano TX, US
Michael Shawn Marshall - Liburn GA, US

International Classification:

B82B 3/00
G01Q 70/14

Abstract:

Improved methods, systems and devices for mechanosynthesis, including those that involve the bulk chemical preparation of tips, multiple tips on a presentation surface, and multiple tips used sequentially in a thermodynamic cascade. These improvements can simplify starting requirements, improve versatility, and reduce equipment and process complexity.

US Patent:

20180136254, May 17, 2018

Filed:

Nov 16, 2016

Appl. No.:

15/353380

Inventors:

Ralph C. Merkle - Cupertino CA, US
Robert A. Freitas - Pilot Hill CA, US
Jeremy Barton - Folsom CA, US
Aru Hill - San Jose CA, US
Michael Drew - Union City CA, US
Damian Allis - Syracuse NY, US
Tait Takatani - Sparks NV, US
Michael Shawn Marshall - Liburn GA, US
Matthew Kennedy - Tucker GA, US

International Classification:

G01Q 70/18

Abstract:

Methods, systems, and devices are described which facilitate mechanosynthesis through the sequential use of a plurality of tips, each of which may have a different affinity for feedstock, thereby allowing tip to tip transfers which enhance system versatility and reduce equipment complexity.
