Abstract: The present disclosure provides an LED light bar that provides off axis lighting. The warning light system includes lights that do not need reflectors that rotate to provide good light effects.

Abstract: A warning light assembly, components therefor and methods of assembly and use are described. The warning light assembly includes a moveable reflector light pod arrangement comprising at least one moveable reflector light pod having a selectively moveable reflector arrangement and a plurality of LED units configured and oriented to direct light against a selectively moveable reflector arrangement. A variety of specific, preferred, features are shown and described.

Abstract: A warning light and warning light assembly are disclosed. The warning light includes a housing including a base and a translucent cover. The warning light includes one or more light emitting diodes within the housing, each of the light emitting diodes operable to emit light substantially along an optical output axis. The warning light also includes a reflector within the housing, the reflector including a reflective surface having a curve section disposed substantially perpendicular to the optical output axis of at least one of the one or more light emitting diodes.

Abstract: A warning light and warning light assembly are disclosed. The warning light includes a housing including a base and a translucent cover. The light also includes a metallized circuit board having a base portion and one or more opposing side portions, the base portion sized to fit within the base and the side portions extending away from the base on opposed sides of the base portion of the circuit board. The warning light also includes a plurality of light emitting diodes on the side portions of the circuit board.

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: An emergency system for a vehicle integrates many disparate equipment into single housing. In one embodiment of the invention, the emergency system is a light bar. The light bar houses various modules for monitoring and responding to events. Example modules include license plate recognition systems and chemical agent detection sensors. The light bar also houses at least one transceiver for wirelessly connecting the light bar to a wide area network, allowing the modules in the light bar to communicate data to and from a remote site. A data terminal in the vehicle is connected to the light bar and receives and displays data to the vehicle operate generated by the modules in the light bar and also from data received over the network.

Abstract: A positive displacement pump and thrust bearing assembly having a housing defining an internal fluid chamber having front and rear inner walls. A rotor having a front face and a rear face is positioned in the fluid chamber. Each of the faces of the rotor is spaced apart from a corresponding inner wall of the fluid chamber to define predetermined clearances therebetween. A shaft is connected at a first end to the rotor to effect rotation thereof. A sealed container surrounds and encloses a second end of the shaft and is in fluid communication with the fluid chamber. The thrust bearing assembly is positioned within the container and includes an adjusting sleeve and an adjusting plate. The adjusting sleeve is attachable to the housing and includes a central bore through which the shaft extends. The adjusting plate is connectable to the shaft such that the sleeve is located between the housing and the adjusting plate.

Abstract: A magnetic drive mechanism and cooling system for driving a rotary pump having a magnetic rotary drive member with a recess therein. A magnetic rotary driven member is located in the recess of the drive member. A container is located between the drive member and the driven member for preventing the escape of cooling fluids circulated therein. Inlet and outlet fluid passages extend through the housing of the drive mechanism to the fluid containment area. Another fluid passage extends from the fluid containment area into the chamber of the pump. A cooling fluid is pumped through the fluid passages at a higher pressure than the pressure of the pumped fluid within the pump to prevent flow of the pumped fluid into the fluid passages and containment area of the drive mechanism to avoid contamination thereof while the cooling fluid is circulated to cool the driven member.

Abstract: A magnetically driven pump and drive mechanism having a rotary driving member with a recess therein and a first magnetic surface thereon, a rotary driven member located in the recess of the driving member and having a second magnetic surface on its periphery, a container located between the drive member and the driven member for preventing the escape of cooling fluids circulated therein, a hub connected to the rotary driven member, at least one port through the hub providing for the passage of fluid from the first side of the hub to the second side of the hub, and a gap between the driven member and the container which provides a second fluid passage between the first side of the hub and the second side of the hub. The port and gap combine to provide a fluid circulation path to allow constant fluid circulation between the first side of the hub and the second side of the hub, thereby cooling the rotary driven member.

Abstract: A hermetically sealed float switch having a bistable ball cage therein. The ball cage is free to pivot between either of two spring biased, over center positions responsive to the position of a ball which is free to roll from either end of the race through the cage to the other end of the race. An over center spring holds the ball cage in its last operated position. A safety arm prevents the ball cage from changing its attitude in any manner which, if uncontrolled, might permit the ball to escape into an inoperative position which might capture it behind the ball cage. Adjustment is provided for the on and off levels of the switch responsive to tether length.
