Title:
CAPACITIVE SENSING CIRCUITS AND METHODS FOR DETERMINING EYELID POSITION USING THE SAME
Document Type and Number:
Japanese Patent JP2018101137
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide sensor systems for ophthalmic devices.SOLUTION: The sensor systems comprise: a first electrode configured to be selectively overlaid with one or more of an upper eyelid 110 and a lower eyelid 112 of a user; a second electrode configured to be selectively overlaid with one or more of the upper eyelid 110 and the lower eyelid 112 of the user; and a system controller 114 cooperatively associated with the first electrode and the second electrode to receive a capacitance measurement from the first electrode and the second electrode, the system controller configured to determine a position of one or more of the upper eyelid 110 and the lower eyelid 112 in spatial coordinates on the basis of the capacitance measurement received from the first electrode and the second electrode.SELECTED DRAWING: Figure 1
