Method and System for Determining the Orientation of an Ophthalmic Lens
First Claim
Patent Images
1. A method for determining the orientation of an optical device, the method having the steps of:
- associating said optical device with at least one first data carrier at a first predetermined position, and at least one second data carrier at a second predetermined position,causing said at least one first data carrier to emit a first signal to an external means and causing said at least one second data carrier to emit a second signal to said external means,processing said first signal and said second signal to determine the first coordinates of said at least one first data carrier and the second coordinates of said at least one second data carrier, with respect to a reference point, to provide a relationship between said first coordinates, second coordinates and said reference point,comparing said relationship to a predefined relationship between said first predetermined position and said second predetermined position with respect to said reference point in a preferred orientation of said optical device.

8. A method for determining the orientation of an optical device, said method including the steps of:
-
associating said optical device with said data carrier means for carrying data related to said optical device, said least one data carrier comprising a device operable in at least one of an electrical mode and/or a magnetic mode to emit said data, said data carrier means having a unique identifier; locating said at least data carrier at a predetermined position on said optical device, said predetermined position correlated to a preferred orientation, receiving signals from said least one data carrier incident on at least two receivers of an external means; determining the identity of said least one data carrier based on at least one of distance, and an angle of arrival of said signals from said least one data carrier; comparing said distance and angle of arrival to predefined values indicative of said predefined orientation; and issuing at least one advisory signal indicative of actual orientation of said optical device based on said comparison. - View Dependent Claims (9, 10, 11, 12, 13)

14. A system for determining the orientation of an optical device, the system comprising:
-
said optical device having at least one data carrier for carrying data related to the optical device, the data carrier comprising a device operable in at least one of an electrical mode and/or a magnetic mode to emit said data;
said at least one data carrier being located at a predetermined location on said optical device;an external means for receiving said emitted data; and a processor associated with said external means for analyzing said emitted data to determine whether said lens is in a preferred orientation. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A computer-readable medium containing program instructions stored thereon, which when executed by a processor cause the processor to perform operations comprising:
-
causing a data carrier included with a ophthalmic lens to emit a data signal periodically, automatically, or in response to a external signal from said the data carrier, wherein said data carrier comprising a device operable in a magnetic and/or electrical mode, outputting information related to said data signal, and wherein said information comprises at least one of a SKU, unique ID, manufacturer, logo, material of manufacture, composition, lot no., batch no., warehouse related data;
promotional material (rebate for next pair purchase or free trials), lens features and benefits data, health warnings, data on potential risk or complications, insurance coverage data, regulatory data, authenticity data, fitting details, orientation of the lens (inside-out/right side-out or convex surface/concave surface), lens type data, lens care or handling information, recommended usage information such as wear schedule, frequency of wear, compliance data, compliance-related statistics, lens ordering data, filling pharmacy, health professional information, time data, an ophthalmic lens user'"'"'s personal details, prescription information, right eye/left eye identification data, expiration data, a URI, spectral passing band(nm), UV cut-off, optical refractive index, Abbe value, transmittance % or haze(%) for a particular thickness, lens case replacement schedule, and eye examination schedule. - View Dependent Claims (22, 23)
