Abstract: A holder for mounting a communication device to a grease gun, which has a housing and a control disposed within the housing, includes a bracket connected with the grease gun. The bracket has a first end coupled with the grease gun housing and a second end coupleable with the communication device so as to secure the device to the grease gun. Preferably, the holder further includes a frame coupled with the bracket second member for receiving the communication device to removably couple the communication device with the grease gun. The communication device may be a smartphone, a portable media player, a portable computing device or any similar device and wirelessly communicates with a control within the grease gun housing.

Abstract: A magnetic bearing assembly is for levitating a generally drum-shaped, vertical rotor such that the drum itself is the target of magnetic actuators. The magnetic bearing assembly basically includes at least one active radial actuator configured to center the drum-shaped rotor in an annular air gap so as to enable contactless rotation. The one or more radial actuators are configured to act principally against gravity and is/are located in essentially the same vertical plane as a center of gravity of the drum-shaped rotor.
