Patent number: 9675444Abstract: Many modern implantable ophthalmic devices include electronic components, such as electro-active cells, that can leak harmful substances into the eye and/or surrounding tissue. In the implantable ophthalmic devices disclosed herein, electronic components are hermetically sealed within cavities formed by bonding together two or more glass wafers. Bonding the glass wafers together with laser fusion bonding, pressure bonding, or anodic bonding creates a seal that leaks at a rate of less than about 5×10?12 Pa m3s?1 when subjected to a helium leak test. Hermetically sealed feedthroughs formed of conductive material running through channels in the wafers provide electrical connections to components inside the sealed cavities. In some cases, the conductive material has a coefficient of thermal expansion (CTE) that is roughly equal to (e.g., within 10% of) the CTE of the glass wafers to minimize leakage due to thermally induced expansion and contraction of the conductive material and the glass wafer.Type: GrantFiled: March 13, 2015Date of Patent: June 13, 2017Assignee: ELENZA, INC.Inventors: Ronald D. Blum, Amitava Gupta, Jean-Noel Fehr, Jean-Christophe Roulet, Urban Schnell, Walter Doll, Roland Michaely

Patent number: 9259309Abstract: Ophthalmic devices with dynamic electro-active elements offer variable optical power and/or depth of field that restore lost accommodation in individuals suffering from presbyopia or aphakia. An illustrative device senses physiological processes indicative of the accommodative response and actuates a dynamic electro-active element to provide the desired change in optical power and/or depth of field. The illustrative device includes two application-specific integrated circuits (ASICs) for processing the accommodative response and actuating the electro-active element: a high-voltage ASIC that steps up a low voltage from a power supply to a higher voltage suitable for actuating the electro-active element, and another ASIC that operates at low voltage (and therefore consumes little power) and controls the operating state of the high-voltage ASIC. Because each ASIC operates at the lowest possible voltage, the illustrative ophthalmic device dissipates less power than other ophthalmic devices.Type: GrantFiled: June 17, 2011Date of Patent: February 16, 2016Assignee: ELENZA, INC.Inventors: Jean-Noel Fehr, Walter Doll, Urban Schnell

Publication number: 20150088253Abstract: Systems and methods of the disclosure relate to managing power consumption of an implantable device, such as an implantable ophthalmic device, that includes one or more rechargeable batteries and a processor operably coupled to the rechargeable batteries. The processor can be configured to implement a quick-charge process that includes charging each rechargeable battery for a first time interval using a first constant current, for a second time interval using a second constant current less than the first constant current, and for a third time interval using a constant voltage. This quick charge process is faster than conventional charging. The processor also manages discharge of two batteries in an alternating fashion so as to increase time between charging cycles, reduce the total number of charging cycles, and extend battery life.Type: ApplicationFiled: March 14, 2013Publication date: March 26, 2015Inventors: Walter Doll, Jean-Noel Fehr, Urban Schnell, Roelof Trip, Amitava Gupta

Patent number: 8697278Abstract: A battery cell casing comprises a first casing element (1) with a first contact surface (7) and a second casing element (2) with a second contact surface (8).

Publication number: 20130242256Abstract: A sensor system includes at least two sensors for distinguishing accommodative stimuli from changes in ambient lights levels and task-induced changes in the pupil diameter. When implanted, the first sensor is disposed completely within the pupil; even when fully constricted, the pupil does not occlude the first sensor, allowing the sensor to make precise measurements of ambient luminous flux levels. The pupil occludes part of the second sensor's active area(s) as the pupil dilates and constricts. As a result, the second sensor measures both ambient luminous flux and pupil diameter. A processor estimates the pupil diameter and determines whether it's changing in response to accommodative stimuli or other factors by comparing to predetermined values. The sensor system sends a signal to an optical component, which in turn can respond by changing optical power to focus for near vision upon detection of accommodative stimuli.Type: ApplicationFiled: September 12, 2011Publication date: September 19, 2013Applicant: Elenza, Inc.Inventors: Jean-Noel Fehr, Urban Schnell, Walter Doll, Roland Michaely, Jean-Christophe Roulet, Amitava Gupta, Ronald Blum, Rudy Mazzocchi
