摘要： Highly efficient particulate collectors, such as for dust and street debris collected by a mobile street cleaning vehicle, with very low pressure loss are disclosed. One embodiment uses a specially contoured passage to separate the solid particles from particulate-laden gas stream by rapid directional change at a throat region. By using the Venturi effect at the accelerating zone communicating with a gas return channel from the particulate retaining chamber, a small amount of the gas will be recirculated from the deposit zone to help move and retain the separated particles in a confined collection receptacle.

摘要： A signaling system for mounting to an exterior surface of an emergency vehicle opposite an interior surface of the vehicle to which objects are mounted is provided. The signaling system includes a light bar having a plurality of signaling devices supported on and distributed along a base member and enclosed by a cover. A plate is secured to the exterior surface of the emergency vehicle by one or more fasteners of a first type, which pass through the vehicle into its interior. The plate includes a surface for engaging the base of the light bar such that the light bar can be suspended from the plate. An opening is provided in the plate for communicating electrical wiring to the light bar. One or more fasteners of a second type that do not pass through the surface of the vehicle into its interior are provided for securing the light bar to the plate and thereby the exterior surface of the emergency vehicle such that the light bar can be removed from the exterior surface of the vehicle without removing the fasteners of the first type, which hold the plate to the vehicle.

摘要： The invention provides a debris separation-filtration unit comprising a housing; an inlet that receives debris-laden air delivers the air in a tangential, centrifugal airflow-forming manner to the interior of housing; an inner shell that includes a number of airflow passageways; and a debris-capturing filter, the sides of which filter are at least substantially surrounded by the inner shell. Due to the formation of the centrifugal airflow and presence of the inner shell in the housing, only a portion of the debris particles entering the unit come in contact with the filter. The invention also provides debris collection, separation, and filtration systems comprising one or more of the separation-filtration units of the invention; debris collection vehicles comprising one or more of such units or systems; and related methods of collecting, separating, and filtering debris.

摘要： Light bars, and lighting systems and vehicles that include light bars. The light bars include a plurality of light emitting modules coupled together at flexible joints to allow a single light bar to be affixed to surfaces of varying curvatures, such as an interior window surface of a vehicle. The size of the light bar is easily customizable due to its modular nature. In some examples, a controller or other electronic element is adapted to detect a number and/or configuration of modules in a given light bar.
