An online concierge system delivers items from retailers to customers. The online concierge predicts a range of times during which an order may be fulfilled for presentation to a user. The online concierge system uses a trained maximum time prediction model to determine a maximum time for order fulfillment based on an order. A trained minimum time prediction model determines a minimum time for order fulfillment from the order and the maximum time. The minimum time may account for one or more rules (e.g., a percentage of orders fulfilled before the minimum time, a desired rate of selection of a range including the minimum time). A range bounded by the maximum time and the minimum time is transmitted to a customer to enable the customer to select a time interval for order fulfillment.

Generating a range of estimated fulfillment times for an order based on characteristics of an order

A power supply and methods are provided. In one implementation, the power supply includes a switching circuit and a converter. The switching circuit includes a first transistor and a second transistor, and the converter includes a capacitor and an inductor. The switching circuit alternately switches an input voltage to the converter. The power supply further includes a controller operable to adjust a switching frequency of the first transistor and the second transistor to substantially match a resonant frequency of the capacitor and the inductor.

A power supply and methods are provided. The power supply includes a bi-forward converter and a feed forward circuit. The bi-forward converter is operable to convert an input voltage into an output voltage. The feed forward circuit is operable to detect a peak voltage associated with the input voltage, and the bi-forward converter is further operable to adjust the output voltage responsive to the peak voltage detected by the feed forward circuit.
