US Patent:

6694796, Feb 24, 2004

Filed:

Jan 23, 2001

Appl. No.:

09/767386

Inventors:

Phillip J. Juneau - Raleigh NC
Robert Baxter - Raleigh NC

Assignee:

B3 Systems, Inc. - Raleigh NC

International Classification:

G01N 3100

US Classification:

73 103, 73 108, 7386323, 7386381, 7386311

Abstract:

An apparatus for calibrating a particulate matter continuous emission monitoring system includes: a feed unit that supplies particulate matter of a known mass flow rate; an eductor unit connected with the feed unit that receives particulate matter therefrom; a fluidizing unit connected to the eductor that supplies gas to the eductor unit, wherein the particulate matter and gas are combined into a fluidized mixture; and a probe connected to the eductor configured to extend within an industrial stack and deliver the fluidized mixture therein. Such an apparatus can provide accurate data regarding particulate matter concentration that can be compared with readings on the PM CEMS and enable a calibration curve to be generated. A tracer gas injection unit and analyzer may also be included.

Appl. No.:

09/844537

Inventors:

Robert Baxter - Raleigh NC, US
Ralph Bard - Raleigh NC, US

International Classification:

G06F012/00

US Classification:

707/200000

Abstract:

Embodiments of the present invention provide methods, systems, and computer program products for communicating with a controller in real-time by storing a command for the controller in a database. The command may be a command to write a value of a real-time process control variable to the controller or a command to read a value of a real-time process control variable from the controller. Upon detecting the stored command in the database, the stored command is retrieved from the database and sent to the controller.

International Classification:

H03K 7/04

US Classification:

375239

Abstract:

A method and apparatus for reducing the number of DQ pins and current used to access data in a memory system or data transfer device, wherein an additional bit is temporally encoded on a data word during a singular access cycle. During an access cycle, the pulse level or levels of encoded bits may determine one or more bits values in a data word being expressed, while the pulse/pulses position in time within a data access cycle determines the remaining bits.

International Classification:

G01N 33/00
G01N 9/00

US Classification:

73 103, 73 3001

Abstract:

A method validating a particulate monitoring device includes generating a final gas stream having a particulate material concentration that corresponds to a target particulate material concentration, using the particulate monitoring device to measure the particulate material concentration in the final gas stream, and evaluating an accuracy of the particulate monitoring device based on a comparison of the particulate concentration in the final gas stream that was measured by the particulate monitoring device with the target particulate material concentration.

Derrick Hinkle - Louisburg NC

Assignee:

B3 Systems, Inc.

International Classification:

G01N 100

US Classification:

7356351

Abstract:

The present invention provides a sampling apparatus for taking a representative gas sample from a flowing gas stream. The sampling apparatus can be positioned within a conduit carrying a gas stream, such as a gas line or smoke stack. Preferably, the sampling apparatus comprises a cylindrical collection tube having collection wings radially projecting therefrom. It is further preferred that the bottom edges of the collection wings contain at least one elongate collection opening, through which a representative gas sample enters the sampling apparatus. In particular embodiments of the invention, the sampling apparatus further comprises an electronic sensor positioned within the collection tube. Alternatively, the sensing device is located at a site remote from the collection tube and is connected thereto by a connecting hose.
