Patent number: 11703698Abstract: Eyeglasses may include one or more lenses and control circuitry that adjusts an optical power of the lenses. The control circuitry may be configured to determine a user's prescription and accommodation range during a vision characterization process. The vision characterization process may include adjusting the optical power of the lens until the user indicates that an object viewed through the lens is in focus. A distance sensor may measure the distance to the in-focus object. The control circuitry may calculate the user's prescription based on the optical power of the lens and the distance to the in-focus object. The control circuitry may adjust the optical power automatically or in response to user input. The object viewed through the lens may be an electronic device. The user may control the optical power of the lens and/or indicate when objects are in focus by providing input to the electronic device.Type: GrantFiled: August 28, 2019Date of Patent: July 18, 2023Assignee: Apple Inc.Inventors: Miikka M.

Patent number: 11552454Abstract: Integrated laser sources emitting multi-wavelengths of light with reduced thermal transients and crosstalk and methods for operating thereof are disclosed. The integrated laser sources can include one or more heaters and a temperature control system to maintain a total thermal load of the gain segment, the heater(s), or both of a given laser to be within a range based on a predetermined target value.

Patent number: 10697830Abstract: A comb light source and spectrometer is disclosed. The comb light source and spectrometer can include a plurality of light emitters, where each light emitter can be configured to emit light included in a plurality of wavelength bands. Each wavelength band can be separated from an adjacent wavelength band by a noise band. Due to the separated wavelength bands for a light emitter, any signal received outside of the one or more wavelength bands can originate from noise (e.g., drift, ambient light, electrical noise), thereby enhancing signal analysis and noise rejection. In some examples, the comb light emitters can be activated sequentially such that a plurality of wavelengths across a spectrum can be measured. In some examples, the resolution and the number of spectral lines in the comb light source can be tuned by changing the properties of the quantum dots and/or increasing the number of comb light emitters.Type: GrantFiled: August 29, 2017Date of Patent: June 30, 2020Assignee: Apple Inc.Inventors: Miikka M.

Patent number: 10401435Abstract: A system for tracking the capacity of a battery in a portable electronic device is described. While the portable electronic device remains plugged in to a power adapter, the system estimates the capacity of the battery by performing the following operations. The system measures a first open-circuit voltage for the battery while the battery rests at a first state of charge. Next, the system causes the battery to transition to a second state of charge. While the battery transitions to the second state of charge, the system integrates a current through the battery to determine a net change in charge for the battery. Next, the system measures a second open-circuit voltage for the battery while the battery rests at the second state of charge. Finally, the system estimates a capacity for the battery based on the first open-circuit voltage, the second open-circuit voltage and the net change in charge. This capacity measurement is repeated and the multiple results are fit to a line.Type: GrantFiled: October 27, 2016Date of Patent: September 3, 2019Assignee: Apple Inc.Inventors: Nils E. Mattisson, P. Jeffrey Ungar, Thomas C. Greening, Jeffrey G. Koller
