Abstract: Multi-semiconductor SSPCs that solve bus level problems affecting systems as well as controller level problems affecting individual multi-semiconductor SSPCs are disclosed. Bus level and controller level problems adversely affect multi-semiconductor SSPCs and their associated systems. The disclosed multi-semiconductor SSPCs solve both bus level and controller level problems by implementing controlled rate-change of voltage (dv/dt) ramp-on rate, to ensure that the voltage on the input bus does not collapse when a multi-semiconductor SSPC is commanded closed and that a minimum amount of power is being dissipated evenly across the switching semiconductors.

Abstract: A trigger mechanism having a hammer, a trigger member, movable ejector lever, and locking member. The trigger member being forced to the set position by the hammer during rearward pivoting. A locking member is adapted to move between a first position at which the locking member mechanically blocks the trigger member from moving to the released position and a second position at which the locking member does not mechanically block the trigger member allowing the trigger member to be moved to the released position. The locking member is spring biased toward the first position and moved against the spring bias to the second position by contact from the movable ejector lever during forward movement of the bolt carrier as the bolt carrier reaches a substantially in-battery position.

Abstract: An online concierge system generates an aggregated lift score for a test feature for the online concierge system. The online concierge presents prioritized items from a set of item groups to two sets of users: a test set and a control set. The online concierge system uses the test feature to present prioritized items to users in the test set, and the online concierge system uses existing functionality to present prioritized items to users in the control set. For each test group, the online concierge system creates holdout subsets out of the test set and the control set. The online concierge system tracks user interactions with items in an item group and computes a group lift score for the item group. The online concierge system generates an aggregated lift score for the test feature based on the group lift scores and presents items to users based on the aggregated lift score.

Abstract: An online concierge system may conduct experiments in presentation of prioritized items for content campaigns with offline simulations. The offline simulation may use a joint budget for the content campaign used by several experimental variations that affect prioritized content presentation. To correct for distortions that may occur from differing rates of budget use in the variations when the budget is reached before a total period for the experiment, the budget use of each variation is compared to a “fair value” to determine an adjustment to the metrics determined in the experiment. Variants that exceed the fair value may have their metrics capping to the portion allocable to a budget use that does not exceed the fair value, while variants that use less than the fair value may have the metrics extrapolated to account for the additional budget that would be available with a fair value budget.
