  • Publication number: 20190223712
    Abstract: 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.

  • Patent number: 10223749
    Abstract: 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.

  • Patent number: 9876145
    Abstract: A flip-chip light emitting diode chip includes a first semiconductor structure, which includes a P-type semiconductor layer, a N-type semiconductor layer, openings, a reflective layer, a barrier layer, a passivation layer, and an electrical contact layer. The openings penetrate the P-type semiconductor layer and a part of the N-type semiconductor layer so as to partially expose the N-type semiconductor layer. The reflective layer is disposed on the P-type semiconductor layer. The barrier layer is disposed on the reflective layer, and the area of the barrier layer is smaller than that of the reflective layer therefore the reflective layer is exposed from the barrier layer. The passivation layer is disposed on the barrier layer and partially fills in the openings. The electrical contact layer disposed on the passivation layer partially penetrates through the passivation layer to contact the exposed part of the N-type semiconductor layer.
