Claim 5:
6. The system of claim 1, wherein the at least one rotorcam is mechanically and electrically coupled to the at least one stator assembly and the at least one cam follower is mechanically coupled to both the at least one stator assembly and the at least one rotorcam, said system further characterized by one or more of the following features:
(5A) the system includes at least one spring coupling the at least one cam follower to the at least one stator assembly, wherein the at least one stator assembly comprises a housing with a first shaped cross-section, wherein the at least one cam follower comprises a shaft with a second shaped-cross section matching the first shaped cross-section of the housing, wherein each of the first and second shaped cross-sections comprises at least one of a triangular cross-section, a square cross-section, an elliptical cross-section, a pentagonal cross-section, a hexagonal cross-section, and a rectangular cross-section, and wherein the shaft is disposed within the housing and is configured to move longitudinally within the housing, and wherein the housing includes at least one damper disposed within the housing;
(5B) wherein the at least one rotorcam comprises:
a center bore concentric about a centerline of the at least one rotorcam; and
a ramp radially disposed around the center bore;

(5C) wherein the at least one rotorcam comprises at least one of neodymium iron boron (Nd—Fe—B), iron, cobalt, samarium cobalt (Sm—Co), aluminum, alnico, bonded Ne—Fe—B, magnetite, ceramic (hard ferrite), ferrite, gadolinium, one or more rare earth elements, strontium, barium, and iron (III) oxide.
(5D) the system further comprises at least one proximity sensor disposed within at least one of the at least one stator assembly and the at least one cam follower;
wherein the at least one proximity sensor is configured to detect a relative position of the at least one cam follower with respect to the at least one stator assembly;
(5E) the system further comprises at least one pressure sensor disposed on at least one of the at least one stator assembly and the at least one rotorcam;
(5F) wherein the at least one rotorcam comprises the center bore, wherein the at least one stator assembly comprises a cylindrical housing, and wherein the cylindrical housing is disposed within the center bore such that the at least one rotorcam extends circumferentially around, and radially outward of, the cylindrical housing; and
(5G) wherein the at least one stator assembly comprises a cylindrical housing, wherein the at least one rotorcam is disposed about the cylindrical housing, and wherein a rotation of the at least one rotorcam about the cylindrical housing causes the change in height of the at least one cam follower.
