Patent ID: 7826145

Claim:
A tunable lens system comprising: a reservoir having at least one flexible wall; a first actuator coupled in relation to the reservoir, the actuator including a first coil that surrounds at least a portion of the reservoir and that is capable of generating a first electromagnetic field and a second coil capable of generating a second electromagnetic field, wherein the first electromagnetic field tends to cause a reduction in a volume of the reservoir, and the second electromagnetic field tends to cause an expansion in the volume; a terminal at which is located at least one of an integrated fluidic lens and a port configured to be coupled to an external fluidic lens, wherein the terminal is coupled to at least one of the reservoir and the actuator, and wherein at least one of the actuator and a first pumping system including the actuator is capable of causing fluid to be moved at least one of from the reservoir toward the terminal, and from the terminal toward the reservoir.
