Jun 5, 1998

Appl. No.:

09/092660

Inventors:

David L. Drake - San Diego CA
David J. Webster - Temecula CA

Assignee:

Intrusion.com, Inc. - Richardson TX

International Classification:

H04L 900

US Classification:

713200, 713201, 709224

Abstract:

A system for event detection employs a collector that collects raw audit data made up of raw audit data records at an audit source; a database; an inserter at a downstream processing location that inserts Virtual Records into the database, including both a first type of Virtual Record generated in response to a raw audit data record, and a second type of Virtual Record generated in response to a detected audit event; the inserter; a parser; coupled to the collector, that converts raw audit data records in the raw audit data into Virtual Records; a detector that detects audit events in response to the Virtual Records generated by the parser, and generates the second type of Virtual Record in the event an audit event is detected.

Appl. No.:

10/062247

Inventors:

David A. Drake - Escondido CA

Assignee:

Pointsource Technologies, LLC - Escondido CA

International Classification:

G01N 2100

US Classification:

356338, 356343

Abstract:

A system for identifying microorganisms and other microscopic particles in a fluid, includes a laser that directs a laser beam ( ) through a detect zone ( ) and a plurality of photodetectors ( ) that detect light scattered in different directions from a particle at the detect zone. The system includes a glass carrier ( ) that confines fluid to movement along a narrow passage ( ) in the carrier. The front surface ( ) of the passage is flat, to facilitate prediction of the scatter light paths, and to enable the passage to have a small cross-sectional area.

PointSource Technologies, LLC - Escondido CA

International Classification:

G01N 2100

US Classification:

356338, 356356, 356343, 356457

Abstract:

An improvement is provided for a system that identifies particles such as microorganisms in fluid by directing a laser beam ( ) forwardly through a tiny detect zone ( ) in the fluid and detecting the pattern of light scatter by a particle as it passes through the detect zone. The improvement includes a holographic optical element ( ) positioned forward of the detect zone to intercept light scattered in multiple directions by the particle. The holographic optical element is divided into discrete areas, or sections, that each directs intercepted scattered light toward a selected photodetector ( ) of a linear array ( ) of photodetectors. A converging lens ( ) reduces the required diffraction angles of the sections of the holographic optical element. This arrangement avoids the need to custom mount and connect numerous individual photocells, and enables simplified high speed readout of the photodetectors.

International Classification:

G08B 1/08
H04Q 7/00

US Classification:

34053926, 34053927, 34087017

Abstract:

A remote sensing system and method for instrumenting the entries to manhole enclosures, in order to provide a platform and means for sensing environmental parameters within and around the enclosures and wirelessly transmitting those parameters to a distant site. The system comprises a housing with sensor for monitoring environmental parameter in the vicinity of the manhole. A microcontroller in the housing sends the parameters to a radio module, which transmits the parameters to a communication device for alerting a user that a manhole has been tampered with.

G08B 23/00

US Classification:

34053926, 3405456, 34053922, 340531

Abstract:

An apparatus for monitoring environmental parameters within an enclosure includes a power source; a communication device electrically connected to the power source and attachable to a cover of the enclosure; and a sensor suspended away from the cover of the enclosure. A method for providing a monitor of environmental parameters within an enclosure includes attaching a communication device to a cover of the enclosure, connecting the communication device to a power source; and suspending a sensor away from the cover of the enclosure. A method for monitoring environmental parameters within an enclosure includes monitoring one or more environmental parameters with a sensor suspended by a cable within an enclosure, and transmitting data representing one or more monitored environmental parameters from a communication device to a second communication device.

Abstract:

An apparatus for generating power in an enclosure includes a power generation device configured to operate in the environmental conditions of the enclosure, a first power storage device connected to the power generation device and configured to store power generated by the power generation device, a power converter connected to the power storage device and configured to output power at a voltage different than that output by the power storage device, and a second power storage device connected directly or indirectly to the power converter and configured to store power output by the power converter. The second power storage device may then provide power for at least one component of an environmental monitoring system.
