  • Patent number: 11927611
    Abstract: A system includes a sensor configured at a first position to sense an orientation of an electricity meter. The electricity meter can be configured at a second position. The electricity meter can be configured at a normal orientation to measure delivered energy sent to one or more locations and received energy received from the one or more locations. The electricity meter can be configured at an inverted orientation to identify and measure the delivered energy sent to the one or more locations and the received energy received from the one or more locations. The sensor is configured to identify when the electricity meter is in the normal orientation, and when the electricity meter is in the inverted orientation. A display is configured within the electricity meter.

  • Publication number: 20050033202
    Abstract: Mechanically activated objects or devices for use in treating degenerative retinal diseases are provided. Such devices apply mechanical forces to tissues of an eye to effectuate treatment and are configured for chronic implantation (thereby applying chronic stimulation/irritation) in or on the eye. The devices may be configured for contact with a retina of the eye, preferably positioned in a subretinal space. Various embodiments comprise a moving member configured for chronic contact with at least a portion of the eye, which moving member is activated by an actuator. In some embodiments, the actuator may be distally located relative to the moving member. Alternatively, the moving member may be supported by a body member that, optionally, also supports the actuator.

  • Publication number: 20050004625
    Abstract: To provide indirect electrical stimulation for treatment of degenerative retinal diseases, such stimulation is applied to surface structures of the eye. A source of an electrical stimulation signal is coupled to a first electrode configured for contact with a first internal surface structure of an eyeball. A second electrode, which may be configured either for contact with an internal surface structure or an external surface structure of the eyeball, is also coupled to the source. The source of the electrical stimulation signal may be implemented internal to a body of a patient, external to the body or through a combined internal/external approach. The first and second electrodes are preferably arranged such that the circuit created by the source, electrodes and intervening biological tissue provides trans-retinal electrical stimulation to thereby effect treatment.
