摘要： A particle measurement system using a single component light collecting system with an aperture having a portion within direct view of the light detector. An aperture assembly extending into a sample may be self-concealing by having an extended portion to block light from directly illuminating the light detector. Alternatively, a smooth, reflective inside surface of the aperture assembly provides for self-concealment by causing spontaneous emitted light to have low angles of reflection. In either case, spontaneously emitted light is substantially prevented from reflecting directly into the light detector, thereby reducing light noise to the level of molecular noise.

摘要： A fluid particle counter comprising an inlet jet tip producing an air flow, a strip laser diode producing a laser beam, and a beam shaping system that includes an aspheric collimating lens, an achromatic spherical lens, a cylinder lens, and a series of cascading apertures. A retarder rotates the polarization so that the TE mode is along the direction of fluid flow. The optical system is designed so that along the flow axis the laser beam is single mode, while the multimodes due to the strip laser are constrained to the dimension perpendicular to the flow. The beam is pinched to a 35 micron waist and has a Gaussian profile along the flow direction which permits locating the beam within 3.5 mm of the flow tip while preventing stray light scattering from the tip. The beam profile along the axis perpendicular to the flow is closer to a square wave than a Gaussian. The particle counter output is substantially free of all noise except noise created by light scattered from molecules of the fluid, even for volumetric particle counters.

摘要： Provided are devices and methods for monitoring flow rate in aerosol particle counters. The particle sensor has a particle counter, a flow measurement orifice comprising a differential pressure sensor for measuring differential pressure (DP) across the flow measurement orifice during particle sensor operation and a critical flow orifice. A vacuum source pulls ambient gas through each of the particle counter, flow measurement orifice and critical flow orifice. An atmospheric pressure sensor measures atmospheric pressure (AP) and a bench pressure sensor measures pressure in the particle sensor (BP). The output from the sensors is used to identify a flow condition, such as by a monitor operably connected to each of the differential pressure sensor, atmospheric pressure sensor and bench pressure sensor. In this manner, deviation in flow rate from a target flow rate is readily monitored without the need for expensive sensors or other flow-controlling components.

摘要： A Download Control Message instructs a set-top terminal in a cable television system to located and immediately begin downloading a code or other data object available over the cable system. The Download Control Message specifies, for example, the size, name, version and location (URL or transport stream and PID) of the object to be acquired by the set-top terminal. The terminal accordingly can begin immediate acquisition of the object. An address or other characteristic associated with the Download Control Message allows the system operator to target the Message to a particular set-top terminal or group of terminals.

摘要： The invention includes a particle sensor with a particle counter. A regenerative blower pulls ambient air into a flow within the particle counter, and a laser illuminates the flow to generate laser radiation indicative of particles within the flow. A detector detects the laser radiation; and particle sensing electronics counts particles within the flow at a preselected volumetric flow rate, e.g., 1 CFM. Preferably, the particle counter includes a plurality of pressure sensors; and a blower speed voltage controller adjusts the speed of the blower according to signals from the pressure sensors to achieve the preselected volumetric flow rate. The regenerative blower permits use of a high efficiency exhaust filter to filter air exhausted from the blower. An airflow path between the particle counter and the regenerative blower preferably has at least one bend between the particle counter and the blower to increase compactness of the system. An aerosol manifold can be connected for fluid communication with an inlet of the particle counter such that the regenerative blower draws air from the manifold at the preselected volumetric flow rate. The manifold samples ambient atmospheric air at a second CFM rate, e.g., 3 CFM, that is greater than the preselected volumetric flow rate. A turbomolecular pump can replace the regenerative blower for high pressure differential particle sensing environments.
