Claim Text:
1. A hose reel comprising: a housing; a length of hose through which a pressurized fluid medium can flow, the hose having a near end connectable to a pressurized fluid medium source, and a far end connectable to a fluid power tool; a drum pivotally connected to the housing and rotatable about a central axis, the drum having a spool shaped periphery for supporting the length of hose when wound thereabout; a motor mounted to the housing, the motor having a rotary output connected to the drum to rotatably drive the drum causing the hose to retract; a rotating coupling having a fixed portion having an input connectable to a pressurized fluid medium source, and a rotatable portion having an outlet connected to the near end of the length of hose; a sensor for detecting the flow of the fluid medium through the length of hose, the sensor generating a sensor signal responsive to fluid flow; a detector receiving the sensor signal and generating an electrical pulse output indicative of fluid flow through the hose; and a programmable processing unit receiving the electrical pulse output of the detector, and generating a motor control signal which can start the motor, wherein the programmable processor is programmed to:
