Abstract: The present disclosure relates to ophthalmic devices such as ophthalmic lenses. An ophthalmic device may comprise an ophthalmic lens for at least one of slowing, retarding or preventing myopia progression. The ophthalmic lens may comprise a center zone with a negative power for myopic vision correction; and at least one treatment zone surrounding the center zone, the at least one treatment zone having a power profile comprising an ADD power, the at least one treatment zone having a surface shape comprising a portion of a generally toroidal shape, wherein the at least one treatment zone is arranged as to form a continuous surface with the center zone.

Abstract: A system and method for providing visual feedback to facilitate multi-code (e.g., barcode) reading (i.e., scanning) is presented. The visual feedback will project a read status for each code scanned. The visual feedback for a particular code will be projected onto that code. For example, an “X” projected onto a code would indicated that this code was not read and needed to be scanned again. This visual feedback minimizes the number of codes that need to be rescanned in the case of a read error.

Abstract: Contact lenses incorporating an array of non-coaxial lenslets with add power that create non-coaxial myopic defocus within the optic zone of the lens may be utilized to prevent and/or slow myopia progression. The positive, non-coaxial lenslets cover about twenty to eighty percent of the central pupil area to deliver positive foci of light in front of the retina to slow the rate of myopia progression.

Abstract: Lenses are designed using the corneal topography or wavefront measurements of the eye derived by subtracting the optical power of the eye after orthokeratology treatment from the optical power before orthokeratology treatment.

Abstract: A vehicle mount computer having a configurable behavior controlled by a vehicle's ignition switch. A user can configure the computer to perform an action, switch modes, or execute a software application in response to the ignition switch being pressed or the position of the ignition switch being adjusted. For example, the computer can be configured to switch to a standby mode or hibernation mode, shutdown, prompt the user to select an action, or do nothing in response to the ignition switch being placed in an off position. The ignition switch can be electrically coupled to an input of the computer so that the computer's operating system or another application can monitor the status of the ignition switch. The operating system or application can cause the computer to perform the configured response upon detecting a change in the ignition switch's position or an actuation of the ignition switch.

Abstract: Ophthalmic lenses incorporate multifocal properties for the purpose of slowing, retarding, controlling or preventing myopia development or progression, correcting presbyopic vision or allowing extended depth of focus. The lens has electronically controlled adjustable focus where the change in focus oscillates so rapidly that it is imperceptible to human vision.

Abstract: Contact lenses incorporate high plus or ADD power profiles that at least one of slow, retard or preventing myopia progression and minimize halo effect. The lens includes a center zone with an ADD power for myopia progression treatment and at least one myopia vision correction power in a peripheral region surrounding the center zone.

Abstract: Methods, systems, and products bridge wireless data transmissions with power-line communications. Should a failure occur in alternating current power, a backup battery maintains the power-line communications. Direct current battery power is used to power a wireless transceiver, thus maintaining both wireless data transmissions and communication during power failures.

Abstract: Lenses are designed using wavefront measurements amenable to correction factors for near and far vision as well as pupil size to slow or stop myopia progression.

Abstract: The present invention is directed to a method for designing a soft contact lens with semi-customized back surface including determining axial radius topography data for a plurality of eyes of a specific population; calculating an apical radius and a conic constant distribution from the axial radius data; determining apical radius and conic constant values for an individual subject; selecting a subset of base curves from a base curve library based on the individual subject's apical radius and conic constant values; and selecting a final base curve from the subset of base curves that fits the individual subject's needs based on one or more selection criteria.

Abstract: A ball retrieving apparatus is formed with a tubular storage chamber on which is mounted a gateway mechanism at the lower end thereof. The gateway mechanism is formed of a cylindrical housing having a passageway therethrough for alignment with the tubular storage chamber engaged therewith. The housing incorporates a ring of spring-loaded detent balls that are biased to project into the passageway to restrict the effective diameter thereof. Balls being retrieved are pressed into the housing to retract the detent balls against the biasing force until the ball has passed the ring of detent balls. The biasing force on the detent balls will retain the collected balls within the tubular storage chamber until the chamber is emptied. The ball retrieving apparatus can be sized to receive any type of sports activity ball.
