Abstract: When a merchant ships a product to a buyer, the merchant may wish to push shipping status updates to the buyer. Moreover, the buyer may wish to receive a notification when a shipping event has occurred in order to remain informed regarding the shipping status of their package without actively checking the package's status with the carrier. In some embodiments, there is provided a computer-implemented system and method that obtains a tracking identifier for a package, transmits the tracking identifier to a carrier's computing interface (e.g. the carrier's API), receives back an indication of the most recent shipping event, predicts the time of a next shipping event at least based on the most recent shipping event, and retransmits the tracking identifier to the computing interface based on the predicted time of the next shipping event.

Abstract: A first noise cancellation winding is disposed between a primary winding and a secondary winding of the planar transformer, and a quantity of coil turns of each noise cancellation winding layer in the first noise cancellation winding is selected to suppress common mode noise generated by the secondary winding or the primary winding and improve noise suppression performance. The first noise cancellation winding is formed by at least two noise cancellation winding layers being connected in series, and other noise cancellation winding layers in the first noise cancellation winding that are connected in series to a first noise winding layer to increase an induced voltage of the first noise winding layer. The foregoing structure allows for a reduced number of coil turns in the first winding layer, compared to existing technology, to reach a required induced voltage.
