  • Publication number: 20240074218
    Abstract: Disclosed herein are organic photosensitive devices including at least one exciton-blocking charge carrier filter. The filters comprise a mixture of at least one wide energy gap material and at least one electron or hole conducting material. As described herein, the novel filters simultaneously block excitons and conduct the desired charge carrier (electrons or holes).

  • Patent number: 8403483
    Abstract: An implantable system for determining the accommodation requirement in an artificial accommodation system by optical measurement of the pupil diameter and the surrounding luminance, including at least one optical system, at least one data acquisition system that does not contact the ciliary muscle and measures a diameter of the pupil and luminance around at least one eye as a physical control signal for the accommodation requirement, at least one data processing system for generating an actuating signal for the optical system from the detected physical control signals or for the purpose of switching to the standby mode, at least one energy supply system, and at least one fixing system. The system has one sensor or a plurality of sensors with sensor elements for measuring the pupil diameter and the surrounding luminance.

  • Patent number: 8043370
    Abstract: The invention relates to a device for restoring the accommodating ability of the eye, which comprises: a) at least one optical system (3) b) at least one data acquisition system (8) that does not touch the ciliary muscle and has either acoustic or optical means to detect the movement of the ciliary body, or it has means to detect the spatial orientation of the two eyeballs with respect to each other, or it has means for measuring the diameter of the pupil and the luminance in at least one eye as a physiological control signal for accommodation c) at least one data processing system to produce a regulating signal for the optical system from the physiological control signal received d) at least one power supply system (10), and e) at least one system for attachment (22).

  • Publication number: 20100324408
    Abstract: The present invention relates to an implantable system for determining the accommodation requirement in an artificial accommodation system by measuring the eyeball orientation using an external magnetic field, comprising a) at least one optical system (3), b) at least one data acquisition system (8) which does not contact the ciliary muscle and has means for measuring a spatial orientation of both eyeballs as a physical control signal for the accommodation requirement, c) at least one data processing system (9) for generating an actuating signal for the optical system (3) from the measured physical control signals, d) at least one energy supply system (10), and e) one fixing system, wherein the system in each case has means for measuring a magnetic field in both eyes and provision is made for transfer means for mutual information exchange between the means.
