Abstract: An electronic horn device may include a horn module, one or more amplifiers, and a controller operably connected to the horn module via the one or more amplifiers. The horn module may be mounted onboard a vehicle. The horn module includes plural compression drivers and a horn body. The horn body includes a bell segment and plural branch segments fluidly connected to the bell segment. The compression drivers are respectively mounted to respective ends of the branch segments of the horn body. The one or more amplifiers are operably connected to the compression drivers of the horn module. The controller is configured to control the compression drivers to generate a horn sound that is emitted from the bell segment of the horn body in response to receipt of a first control signal.

Abstract: An air dryer includes a first flow path through the air dryer and a second flow path through the air dryer in parallel with the first flow path. A diverter valve has a first position that provides fluid communication to the first flow path and a second position that provides fluid communication to the second flow path. A system parameter signal is reflective of fluid flow through the air dryer, and a controller receives the system parameter signal and produces a first control signal based on the system parameter signal. The first control signal controls the position of the diverter valve.

Abstract: A telescoping assembly includes a rod with a recess in the rod. A first collar surrounds the rod, and a detent extends through the first collar. A second collar surrounds at least a portion of the first collar. The second collar has a locked position biasing the detent radially inward through the first collar and against the recess in the rod and an unlocked position allowing the detent to move radially outward through the first collar and away from the rod.
