Abstract: The present invention relates to medical fluid injectors. An exemplary injector may include a drive ram that is adapted to interface with a plunger of a syringe. The drive ram may be equipped with an RF enabled pressure sensor that is configured to measure pressure exerted on the syringe plunger by the drive ram. In addition, the injector may include an RF circuit in RF communication with the pressure sensor of the drive ram. In some embodiments, the injector may include a controller in electrical communication with the RF circuit. The controller may be configured to adjust movement of the drive ram to alter the pressure exerted on the syringe plunger by the drive ram (i.e., the pressure measured by the pressure sensor).

Abstract: A reel for a fishing rod comprises a braking device consisting of a slider movable radially in relation to one of the cheeks of a drum on to which the line is wound, a flexible end of this slider exerting a braking effect which varies according to its radial distance. The cheek of the drum is preferably provided with radially orientated notches.

Abstract: A fishing reel is disclosed which comprises a rotatable line drum and actuating means for rewinding the fishing line onto said drum. Said actuating means include a pulley driven by manually pulling a wire, a return device for said pulley and a unidirectional clutch for temporarily couple the pulley to the line drum for rewinding the line.
