    摘要: Disclosed is a particle sensor having a light beam with a beam long axis and an air flow tube with an inlet end and a particle exit mouth. In an aspect of the invention, the cross-sectional area of the flow passage at the inlet end is greater than the cross-sectional area of the exit mouth. This enlarged area dramatically reduces pressure drop along the tube. The exit mouth is in registry with the light beam and is elongate in a direction substantially parallel to the beam long axis. Thus, particles flowing through the mouth pass through the beam. In another aspect, the invention includes a centrifugal blower which is light in weight and which may be battery powered.

    摘要: An environmental sensor including an inlet and an outlet such that a flow of fluid moves from the inlet to the outlet, a particle detection portion to detect particles in the fluid, and a controller connected to the particle detection portion. The environmental sensor can be in communication with a data acquisition system (e.g., via a wireless access point) to form a particle counting system. Also disclosed are methods of operating the environmental sensor and methods of operating the particle detection system.

    摘要: A portable microbial gaseous-fluid sampler includes a gaseous-fluid flow system at least partially supported by a structure. The gaseous-fluid flow system includes a gaseous-fluid intake portion having an intake port, a blower in fluid communication with the intake port, and a gaseous-fluid exhaust portion having an exhaust port. The sampler can further include an exhaust filter operable to substantially filter a totality of the gaseous fluid flowing through the sampler prior to exhausting the gaseous fluid. The sampler also can include a control system operable to control at least gaseous-fluid flow through the sampler, and a remote sampling head.

    摘要: For connecting a high voltage wire to an elongated terminal of an electrical device, a connector link is provided comprising a first hollow tubing having an open first end with an extending flattened portion of the tubing bent to form the wall of a second hollow tubing having an axis of elongation perpendicular to the axis of elongation of the first tubing. The second hollow tubing is interference fitted onto the terminal and an end of the high voltage wire is inserted into the open end of the first tubing. The wire end is soldered to the first tubing and the second tubing is soldered to the terminal. An abundance of solder is used for causing the solder to flow outwardly from the ends of the tubings to form a continuous well-wetted shape of solder having smooth and rounded surfaces for avoiding concentrated electric fields and attendant electrical discharges.

    摘要: The disclosure involves a particle sensor having a mirror cavity unobstructed by masks and the like. A light detector is at the mirror secondary focal point and well outside the mirror cavity. A variation includes a beam splitter and a secondary light detector to improve detection of larger particles. A second embodiment includes a pair of elliptical mirrors offset along the light beam. Light reflected by the second mirror represents only changes in laser power and light scattered by gas molecules. The resulting signal is subtracted from that produced by the first mirror to obtain a relatively "clean" signal useful to assay very small particles.
