  • Patent number: 10987043
    Abstract: The present systems and methods provide a mechanism to assess viewer behavior, features of stimuli, and the interaction between viewer behavior and stimuli. The systems and methods described herein for quantifying blink response and blink inhibition provide moment-by-moments measurements of viewer engagement by measuring what is or is not engaging enough to warrant viewers' inhibition of blinking. The present disclosure describes measures of visual scanning, eye movements, blink data, and blink timing data to derive a measure of how engaged a person is with what he or she is looking at. Blink-related data as a measure of viewer engagement provides a mechanism for determining the most engaging spatial and temporal aspects of a stimulus.

  • Patent number: 10962737
    Abstract: A lens module comprises a frame, a lens unit, and a driving module for driving the lens unit to move relative to the frame. The lens unit comprises a body made of plastic, at least one lens located in a center of the body, and an embedded member made of metal. The metal embedded member is embedded within a thinner rim portion of the lens unit by means of a plastic insert-molding process in such a manner that, at least one protrusion of the metal embedded member is exposed outside of the rim portion. When the lens unit moves relative to the frame, a location where the lens unit might touch the frame is one of the at least one protrusion, and therefore the structural strength, endure ability of impact and endure ability of friction at the rim portion of the lens unit are increased. In addition, the protrusion can also act as a positioning post or winding post for a coil of the driving module.

  • Patent number: 10920102
    Abstract: The invention is related to a cost-effective method for making a silicone hydrogel contact lens having a crosslinked hydrophilic coating thereon. A method of the invention involves heating a silicone hydrogel contact lens in an aqueous solution in the presence of a water-soluble, highly branched, thermally-crosslinkable hydrophilic polymeric material having positively-charged azetidinium groups, to and at a temperature from about 40° C. to about 140° C. for a period of time sufficient to covalently attach the thermally-crosslinkable hydrophilic polymeric material onto the surface of the silicone hydrogel contact lens through covalent linkages each formed between one azetidinium group and one of the reactive functional groups on and/or near the surface of the silicone hydrogel contact lens, thereby forming a crosslinked hydrophilic coating on the silicone hydrogel contact lens. Such method can be advantageously implemented directly in a sealed lens package during autoclave.
