20120147321 | Contra-Aspheric Toric Ophthalmic Lens - An ophthalmic toric lens to be worn on an eye or implanted inside of an eye, the lens includes an anterior surface, a posterior surface, and a toric shape formed into one of the anterior and posterior surfaces, the toric shape comprising two non-spherical principle meridians each having a region within an annular area of optical zone and the region of one principle meridian being configured for producing a longitudinal ray aberration of a different sign than a longitudinal ray aberration sign from the region of another principle meridian. | 06-14-2012 |
20130035760 | SWITCHABLE DIFFRACTIVE ACCOMMODATING LENS - A lens in accordance with the present invention includes an accommodating cell having two chambers with at least one chamber filled with optical fluid with the refractive index matching the refractive index of the accommodating element separating them. The accommodating element has a diffractive surface with surface relief structure that maintains its period but changes its height due a pressure difference between the chambers to redirect most of light that passes through the lens between different foci of far and near vision. The invention also includes a sensor cell that directly interacts with the ciliary muscle contraction and relaxation to create changes in pressure between the accommodating cell chambers that results in changing surface relief structure height and the lens accommodation. | 02-07-2013 |
20140085726 | REFRACTIVE-DIFFRACTIVE SWITCHABLE OPTICAL ELEMENT - A lens in accordance with the present invention includes an switchable cell consisting of optical substrate with diffraction surface, elastic film in contact with the diffraction surface of the substrate, optical fluid that fills the space between the film and diffraction surface and the mean to transfer the optical fluid in and out of the space between the film and diffraction surface. The refractive index of the optical fluid matches the refractive index of the optical substrate. The switchable cell changes focus positions between refractive focus in relaxed state when the pressure at both sides of the film is the same and diffraction focus when the optical fluid is transported from the space between the film and optical substrate for the film to largely conform to the diffraction surface shape of the optical substrate. | 03-27-2014 |
20140100654 | REMOTE MULTIFOCAL TO MONOFOCAL OPTIC CONVERSION - An ophthalmic multifocal switchable lens includes a deformable element manifesting elevated strain with a formable surface of a multifocal surface shape to provide far and near vision. A transparent chamber is filled with optical matching fluid adjacent to the side of the deformable element opposite to the formable surface. The optical matching fluid has a refractive index that matches a refractive index of the deformable element material. A holding chamber is also filled with the optical matching fluid and connected with the transparent chamber with a means for preventing the optical fluid from being transported from the holding chamber to the transparent chamber which would reduce a strain of the deformable element. A split of light between far and near vision of the multifocal switchable lent changes upon a removal of the means to allow a flow of the optical matching fluid into the transparent chamber. | 04-10-2014 |
20140107777 | IMPLANTABLE OPHTHALMIC SENSOR CELL - An implantable ophthalmic device connectable to an implantable accommodating lens includes a dual-chamber sensor cell having a first and second plate where the second plate is disposed opposite the first plate. A first chamber with a first flexible membrane is disposed on an inner side of the first plate. A second chamber with a second flexible membrane is disposed on an inner side of the second plate. A space resides between the first and second chambers configured to receive a scleral spur of a ciliary muscle of a patient's eye. A connecting element is attached at a first end to the dual-chamber sensor cell. The connecting element includes a first and second channel disposed along a length of the connecting element and in communication with the first and second chamber of the dual-chamber sensor cell, respectively. The second end of the connecting element is connectable to the implantable accommodating lens. | 04-17-2014 |

A pill cartridge has a cartridge body storing a plurality of pills, where the cartridge body includes an electronic tag storing data. A pill cartridge dispenser is configured to receive at least one of the pill cartridge and configured to electromechanically control dispensing of the plurality of pills from the cartridge body, where the pill cartridge dispenser is configured to be in wireless communication with the electronic mobile communication device. The electronic mobile communication device is configured to wirelessly read the data stored on the electronic tag or wherein the pill cartridge dispenser is configured to wirelessly read the data stored on the electronic tag. The electronic mobile communication device wirelessly communicates with the pill cartridge dispenser to dispense at least one pill from the plurality of pills within the pill cartridge. | 02-19-2015 |
