摘要： A pair of eyeglasses may include one or more adjustable lenses that are each configured to align with a respective one of a user's eyes. The adjustable lenses may include a foveated liquid crystal adjustable lens stacked with a non-liquid-crystal adjustable lens such as a fluid-filled lens or an Alvarez lens. The foveated adjustable lens may include electrically modulated optical material such as one or more liquid crystal cells. The liquid crystal cells may include arrays of electrodes that extend along one, two, three, four, or more than four directions. Control circuitry may apply control signals to the array of electrodes in each liquid crystal cell to produce a desired phase profile. Each lens may be foveated such that portions of the lens within the user's gaze exhibit a different phase profile than portions of the lens outside of the user's gaze.

摘要： 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.

摘要： 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. The system can include electrical circuitry configured to distribute current to the gain segment, the heater(s), or both. The heater(s) can be located proximate to the gain segment, and the distribution of current can be based on the relative locations. In some examples, the central laser can be heated prior to being activated. In some examples, one or more of the plurality of lasers can operate in a subthreshold operation mode when the laser is not lasing to minimize thermal perturbations to proximate lasers.

摘要： Some embodiments of the present invention provide a system that accurately and reliably updates a full charge capacity of a battery. During operation, the system charges the battery from an initial state to a rest point prior to reaching a fully charged state. The system then interrupts the charging process to allow the battery to relax to a resting voltage. Next, the system measures the resting voltage. The system then resumes the charging process toward the fully charged state. The system subsequently estimates the capacity of the battery based on the measured resting voltage and one or more other parameters.

摘要： 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. The slope of fitted line is then used to estimate how the true battery capacity has faded since last measured using traditional methods that require the battery to be rested at a low state of charge.

摘要： Some embodiments of the present invention provide a system that estimates a state of charge for a battery. During operation, while the battery is relaxing toward a fully rested state, the system determines if a modified state of charge of the battery is substantially consistent with a predetermined decay pattern. If so, the system estimates the state of charge of the battery as a value of the modified state of charge determined at the time when the consistency is observed. Otherwise, the system continues monitoring the modified state of charge of the battery. In one embodiment, the predetermined decay pattern is a single exponential decay. After estimating the state of charge of the battery, the system may determine an uncertainty of the estimated state of charge. More specifically, the system can estimate the uncertainty as substantially equal to a fraction of the difference between the value of the modified state of charge and the value of the voltage-based state of charge at the time when the consistency is observed.
摘要翻译： 本发明的一些实施例提供一种估计电池的充电状态的系统。 在操作期间，当电池正在朝着完全静止状态放松时，系统确定电池的修改的充电状态是否与预定的衰减模式大致一致。 如果是这样，系统将电池的充电状态估计为在观察到一致性时确定的充电状态的值。 否则，系统继续监视电池的修改充电状态。 在一个实施例中，预定衰减模式是单指数衰减。 在估计电池的充电状态之后，系统可以确定估计的充电状态的不确定性。 更具体地，系统可以将不确定度估计为基本上等于修正充电状态的值与观察到一致性时的基于电压的充电状态的值之间的差的一小部分。
