Filed:

Mar 29, 2013

Appl. No.:

13/853890

Inventors:

Joe Fitzpatrick - Glendale CA, US
Brett Henderson - Salt Lake City UT, US
Anthoniraj Lourdhusamy - West Jordan UT, US
Lee Sorensen - West Jordan UT, US
James Steppan - Park City UT, US

Assignee:

EmiSense Technologies, LLC - San Juan Capistrano CA

International Classification:

G01N 33/00
G01M 15/10

US Classification:

73 2331

Abstract:

A sensor includes a housing, a central sensor electrode assembly, an insulating member, and a trace. The central sensor electrode assembly is coupled to a supply side of a voltage source. The insulating member is coupled between the housing and the central sensor electrode assembly. The insulating member circumscribes a section of the central sensor electrode assembly. The trace is coupled to the insulating member and circumscribes the section of the central sensor electrode assembly. The trace directs at least a portion of leakage current away from a voltage ground offset on an opposite side of the central sensor electrode assembly.

International Classification:

G01M 15/10
G01N 33/00
G01N 15/06

Abstract:

A sensor includes an electrode and a seed structure. The electrode is configured to measure current due to movement of particulate matter relative to the electrode. The seed structure is deposited on the electrode. The seed structure includes a plurality of elongated members extending outward from the surface of the electrode. The elongated members are configured to promote charge transfer to particles and/or agglomerates of the particulate matter during operation of the sensor.
