ACTIVATION SCHEME FOR OPHTHALMOLOGICAL LENSE WITH ELECTRIC POWER Russian patent published in 2017 - IPC A61F2/16 G02C11/00 H03K19/185 G02C7/04 

FIELD: medicine.

SUBSTANCE: electronic system that includes an activation scheme for application in at least one of the following ways: on or inside the body. The electronic system contains: functional electronic components, including a digital controller and an additional circuit; a power supply unit to supply power to the functional electronic components; an activation logic having a storage state and an activity state and configured to detach the power supply from the functional electronic components to minimize the leakage current from the power supply unit in the storage state; a switching element associated with a power source, a logic activation circuit, and functional electronic components; the first power-on reset circuit associated with the power supply unit and the activation logic and configured to provide the correct initial state of the activation logic when the power is turned on and hold the activation scheme in the reset state during power stabilization time of the activation logic; the second power-on reset circuit associated with the switching element and functional electronic components, and configured to provide a correct initial state of the functional electronic components upon power-up; a sensor associated with the activation logic, the sensor being a photosensor. The activation logic is configured to switch from the storage state to the activity state when the sensor is activated in response to a light incident on the light sensor whose intensity exceeds the predetermined threshold or in response to the output signal of the second power-on reset circuit.

EFFECT: application of this invention will minimize active current consumption of the device.
