Claim Text:
1. An apparatus comprising: a plurality of lens assemblies connected to a lens platform; the lens platform slidably connected to a guide; and an electromagnetic actuator comprising: a first magnet connected to the lens platform and arranged in proximity to a first coil; and a second magnet connected to the lens platform at a position complementary to the first magnet, and arranged in proximity to a second coil; wherein the electromagnetic actuator is configured to change a distance between the plurality of lens assemblies and a plurality of image sensors, and further wherein the electromagnetic actuator is configured such that if no current is applied to the electromagnetic actuator, a magnetic force between the second magnet and the guide induces movement of the lens platform relative to the guide and further induces a frictional force between the lens platform and the guide such that the lens platform remains stationary as to the guide.
