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.

Abstract: A robust low profile antenna well suited for deployment on the lids of cavities, such as manholes is described. The antenna is constructed from a coaxial cable for use proximate to a structural surface. The antenna is formed by folding back an outer metallic braid of an end of the coaxial cable to a length that approximately matches ¼ of a wavelength of a desired operating frequency times a velocity factor of the coaxial cable. Next, the radiative element is formed by exposing the center conductor from the end of the coaxial cable to a length that approximately matches ¼ of the wavelength of the operating frequency multiplied by the composite velocity factor being based on a dielectric encasing of the coaxial cable and the distance of the antenna from the structural surface. The antenna is oriented substantially parallel to the structural surface. The resulting antenna is of a comparable size to the coaxial cable.

Abstract: An improvement is provided for a system that identifies particles such as microorganisms in fluid by directing a laser beam (52) forwardly through a tiny detect zone (46) 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 (60) 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 (74, 90, 92) of a linear array (62) of photodetectors. A converging lens (106) 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.

Abstract: A system for identifying microorganisms and other microscopic particles in a fluid, includes a laser that directs a laser beam (14) through a detect zone (20) and a plurality of photodetectors (30) that detect light scattered in different directions from a particle at the detect zone. The system includes a glass carrier (110) that confines fluid to movement along a narrow passage (116) in the carrier. The front surface (130) 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.
