The system also includes a third antenna connected to a second antenna port of the plurality of antenna ports, the third antenna oriented toward the first lane of traffic. In some cases, the RFID reader is configured to detect the existence of a vehicle in a lane based on detection of an RFID device associated with the vehicle at two or more of the plurality of antenna ports. | 12-15-2011 |
| 20110211349 | ROTATING LIGHT - The present disclosure provides a lighting device that includes an array of LEDs arranged on a circuit board with a reflector that rotates relative to the LEDs to reflect the light in various directions. The reflector according to the present disclosure includes a compact construction that allows for effective light reflection. A related lighting system and method is also provided. | 09-01-2011 |
| 20110156589 | LIGHT BAR AND METHOD FOR MAKING - 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. | 06-30-2011 |
| 20100012333 | PUMP MODULE CONTROL SYSTEM HAVING A SERIAL LINK - A control system for a pumping system in a pumping vehicle is disclosed. The control system includes a valve controller unit having an addressable communication module configured to exchange control and status data regarding a pump valve with at least one valve interface unit. The control system also includes a valve interface unit having an addressable communication module configured to exchange control and status data regarding a pump valve with at least one valve controller unit. The control system further includes a serial communication link communicatively connecting the valve interface unit and the valve controller unit. | 01-21-2010 |
| 20100012332 | REMOTELY LOCATED PUMP CONTROL SYSTEM - A control system for a pumping system of a pumping vehicle is disclosed. The control system includes a valve control unit communicatively connectable to a plurality of valve interface units of one or more pumping vehicles, the valve control remote from at least one of the one or more pumping vehicles and configured to independently exchange control and status data with the plurality of valve interface units regarding at least one pump valve associated with each of the plurality of valve interface units. The control system also includes a valve interface unit communicatively connected to the valve control unit, the valve interface unit configured to exchange control and status data regarding the pump valve with the valve control unit. Methods of communicating commands in a control system and a fire apparatus are also disclosed. | 01-21-2010 |
| 20100011523 | SIDE BROOM HAVING MEMORY RECALL AND METHOD FOR PERFORMING THE SAME - The present disclosure relates generally to debris collection devices. In particular, the present disclosure relates to a debris collection vehicle utilizing a side broom having memory recall functionality. | 01-21-2010 |
| 20090303716 | LIGHT ASSEMBLY - A light assembly is disclosed which can include an LED array and a reflector. The LED array can include a plurality of LEDs which are disposed such that each LED is substantially aligned to define a focal axis. Each LED can emit light substantially along an optical output axis, with each optical output axis being perpendicular to the focal axis. The optical output axis of the LED array can be disposed in intersecting relationship with the reflector surface. The reflector can be defined by a curve section defined with respect to a principal axis. The principal axis and the output axis of the LED array can be in non-parallel relationship with each other. The optical output axis of the LED array can be substantially perpendicular to the principal axis of the curve section of the reflector. | 12-10-2009 |
