  • Patent number: 10181013
    Abstract: A pill dispensing system includes an electronic mobile communication device with a wireless transmitter and receiver. 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.

  • Patent number: 9622855
    Abstract: 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.

  • Patent number: 9510939
    Abstract: A switchable intraocular lens assembly includes an optic body having a guiding surface, a holding chamber, a blocking channel, and a laser accessible cavity at a portion of the blocking channel. An elastic film is disposed over the guiding surface, wherein the elastic film is sealed at or near the guiding surface periphery forming a transparent chamber between the guiding surface and the elastic film. A laser flowable blocking element has an enlarged head connected to an extension portion, where a length of the extension portion is more than a distance along the blocking channel from the blocking channel opening to the fluidic connection of the transparent chamber. The extension portion of the laser flowable blocking element is disposed inside the blocking channel. An optical fluid is disposed within the holding chamber under a pressure greater or lesser in comparison to a pressure in the transparent chamber.

  • Patent number: 8397946
    Abstract: A cartridge based dispensing system includes a cartridge having a rotatable compartmentalized receptacle for supporting a plurality of items in separate compartments along with a housing for removably supporting the cartridge. The housing includes an opening for enabling dispensing of an item from an aligned separate compartment and a mechanism is provided for rotating the receptacle within the cartridge in order to align compartments with the housing opening. The mechanism may be configured for causing different discrete angular rotations of the receptacle corresponding to compartment size.
