Apparatus And Method For Multi-Channel Materials Assaying

US Patent:
8346496, Jan 1, 2013
Filed:
Aug 10, 2010
Appl. No.:
12/853634
Inventors:
David Brecht - San Diego CA, US
Patrick Bird - San Diego CA, US
Assignee:
Wildcat Disocovery Technologies, Inc - San Diego CA
International Classification:
G01R 19/00, G01R 15/00, G01R 29/00, G01R 31/00, G01R 31/01, G01R 31/02
US Classification:
702 64, 702 57, 702 65, 324415, 324522, 324537
Abstract:
A system for assaying electronic or electrochemically active materials or devices made therefrom includes a microcontroller, a main digital-to-analog converter (DAC), current and voltage sensing modules, a reference voltage DAC, and a power switch. The reference voltage DAC applies a calibrated voltage across the materials/devices, and the switch disconnects the main DAC to generate an open-circuit voltage. The microcontroller assays the materials/devices using the measured voltage, measured current, reference voltage, and/or open-circuit voltage. The main DAC may include coarse and fine DACs. A method of assaying the materials/devices includes measuring an electrical current in and a voltage across the materials/devices using the respective current and voltage sensing modules, applying a reference voltage across the materials/devices using the reference voltage DAC, activating the switch to disconnect the DAC to generate the open-circuit voltage across the materials, and using the microcontroller to assay the materials/devices as noted above.

Liquid Infusion Device And Method

US Patent:
2012009, Apr 19, 2012
Filed:
Oct 13, 2011
Appl. No.:
13/272469
Inventors:
Justin James Dutton - San Diego CA, US
Paul Christopher Ziegelbauer - San Diego CA, US
Doron Greenberg - Agoura Hills CA, US
David James Brecht - San Diego CA, US
Bin Li - San Diego CA, US
Assignee:
Wildcat Discovery Technologies - San Diego CA
International Classification:
C23C 14/00
US Classification:
118 50, 427294
Abstract:
A device for infusing liquid into material samples includes a container assembly configured to contain multiple material samples submerged in liquid. The material samples have pores containing air or gas. A pressure source and a vacuum source are both operatively connectable to the container assembly and alternately communicable with the container assembly to force the liquid to at least substantially fill the pores. The samples are thus ready for further processing, testing or use. A method of filling pores in material samples with liquid includes supporting multiple material samples within liquid in an airtight container assembly. The method further includes alternately applying a vacuum source and a pressure source to the container assembly, thereby replacing air with liquid in the pores of the material samples.
