Publication number: 20190223712Abstract: An eyelid opener and an eyelid opening and sensing device are provided. The eyelid opener has a housing, two eyelid pushers and one eye positioning unit. The eye positioning unit abuts the surrounding of the eye socket for positioning (e.g. one side of the nasal bridge), and then the sensing process (e.g. eye pressure, eye temperature) of an eyeball sensor is started, ensuring the inspected region remains the same for each measurement. By contacting the user's face, the eyelid opener can be operated by the user independently. The positioning process ensures the eyeball sensor and the eyeball are placed at a fixed distance to prevent the eyeball sensor from physical contacting or hurting the eyeball and to facilitate mounting the eyeball sensor near the eyeball. The two eyelid pushers can avoid unconscious blinking during the sensing process.Type: ApplicationFiled: January 24, 2018Publication date: July 25, 2019Inventors: HORNG-JI LAI, LI-PING YU, HSIANG-CHING LEE, TE-LUN MA, CHANG-YUAN FAN, CHEN-HAO KAN

Patent number: 10223749Abstract: Retirement planning methods and systems for use with an individual investor having a retirement plan comprising assets and future liabilities. One or more computing devices perform the methods. Embodiments of the methods include determining a net present value of the assets and a net present value of the future liabilities. A funded ratio is calculated as a function of the net present value of the assets and the net present value of the future liabilities. If the funded ratio is less than a predetermined threshold value, the retirement plan is at risk of being underfunded. If the funded ratio is greater than the predetermined threshold value, the retirement plan is not at risk of being underfunded. An indication may be displayed indicating whether the retirement plan is at risk of being underfunded.Type: GrantFiled: November 7, 2013Date of Patent: March 5, 2019Assignee: RUSSELL INVESTMENTS GROUP INC.Inventors: Rod Steven Greenshields, Grant Walter Gardner, Samuel David Pittman, Steven M.
