Abstract: A light bar is described that is of a modular construction based on one or more large circuit boards that are populated with light beam assemblies and then fastened to an interior space of the light bar housing. Keys that automatically align the light beam assemblies on each of the boards precisely control placement of the assemblies on the board. In turn, each of the boards is keyed to the interior of the light bar housing so that when the board is fastened to the housing the light beam assemblies are automatically registered into alignment with the lenses in the housing so that the beams from the assemblies are properly oriented. The light bar is inexpensive to fabricate and can be assembled quickly and reliably, yet it provides for a high degree of customization, which is a requirement in the emergency vehicle lighting industry.

Abstract: A warning light and a method of providing a warning light signal are disclosed. A warning light includes a control system configured to receive a power supply and generate a pulsating output. At least one light-emitting diode (LED) array is configured to receive the pulsating output and generate a pulsating light having a predetermined intensity and appearing to a human eye to include a steady-state light.

Abstract: Embodiments of the invention include a dust extraction system including an array of two or more centrifugal dust removal devices, e.g., axial cyclones. The array of axial cyclones is configured to operate in parallel. The array of axial cyclones includes one or more sensor and a controller in communication with the sensor and adapted to receive air flow information from the one or more sensor. Inflow valves are operatively connected to the controller such that air flow through the array of axial cyclones is monitored and maintained at an optimum operating condition for each of the individual cyclones in the array. This is done, in general, by opening inflow valves as the air flow increases above a predetermined air flow value and shutting inflow valves as air flow decreases below the predetermined air flow value threshold.

Abstract: The invention provides debris collection devices that include a debris contacting mechanism, a debris transport mechanism that is configured to receive debris moved by the debris contacting mechanism at an inlet and move such debris towards a debris storage compartment, and a filter and vacuum assembly. The filter and vacuum assembly includes an inlet disposed downstream of the inlet of the transport mechanism and upstream of the debris storage compartment, relative to the path of transported debris. In operation, the filter and vacuum assembly generate a primary air flow that draws the airborne particles into the inlet of the transport mechanism, along a path proximate to the transport mechanism, into the inlet of the filter and vacuum assembly and though a filter located within the filter and vacuum assembly without generating a substantial airflow through the storage compartment. Related debris collection and processing systems and methods also are provided.

Abstract: A communications infrastructure is upgraded to a public safety network that supports wireless communications of emergency information. Communities have installed public safety communications systems such as community warning siren systems that rely on point-to-point communications systems. Each site in the system is upgraded to a node in a wireless network that provides the communications infrastructure for a network-enabled public safety communications system that enables trusted resources such as warning sirens to access the network and communicate with other trusted resources across the network. Additionally, the public safety network may be patched using mobile transceivers to form an ad hoc network in the event part of the infrastructure supporting the emergency response network is lost. Additionally, the upgrading of the communications system may include a public access network that relies on at least some of the same communications sites or nodes employed by the public safety network.

Abstract: A communications system for one or more of a community's public safety resources is upgraded to include a public safety network. Assets owned by one of the public safety resources may be controlled over the network from a remote command center that compiles information from the network-enabled resources in the community to enhance the ability of the assets to effectively deployed in an emergency situation. The upgraded communications system at the public safety resources also enables trusted resources, such as the assets owned by the public safety resources, to access the network and communicate with additional trusted resources throughout the community. Additionally, the public safety network may be extended using mobile transceivers to form an ad hoc network in the event part of the infrastructure supporting the network is lost.
