Abstract: An apparatus providing an assist force to user moved weight of an existing un-motorized exercise or rehab machine or stand includes an assembly with operably connected motor and reel, a human-machine interface (HMI) that accepts input of variable parameters for assist control including entry of at least a user selected assist force and number of movement repetitions, a motor drive and a main digital controller connected with at least the motor, motor drive and HMI. The controller is programmed to provide a user selected non-zero assist force essentially only during parts of an exercise and a nominal static or drag force at other times. A cable has a first end securable to the reel and a second end configured to be coupled directly or indirectly with the weight to be moved by the user. The apparatus can be supplied in kit form.

Abstract: An apparatus providing an assist force to user moved weights of a existing weight exercise or rehab machine or stand can be supplied as a kit including servo motor/transmission/reel assembly. A cable has a first end securable to the reel and a second end configured to be coupled directly or indirectly with the user moved weights of the existing machine/stand. A control interface accepts input of variable parameters for assist control including entry of at least a user selected assist force. The kit also has a servo drive and a main digital controller connected with at least the servo motor, motor drive and control interface, the controller programmed to provide a user selected non-zero assist force essentially only during part of an exercise.

Abstract: The present invention provides novel anti-infectives that act on Staphylococcus aureus (S. aureus) iron-regulated surface determinants, IsdA, IsdB, IsdC, IsdH (or HarA).
