Abstract: This disclosure relates to the field of metallurgical automation technologies, and discloses a method and device for cross-process use of cold/hot-rolled excess material, medium, and program product. The method is applied in an electronic device. In this method, multiple futures contracts and multiple cold/hot-rolled excess materials with same steel grade are obtained, forming at least one matching pair consisting of a futures contract and a cold/hot-rolled excess material by taking the multiple futures contracts and the multiple cold/hot-rolled excess materials as nodes in a weighted binary graph, to construct a matching relationship graph. In addition, a matching weight of each matching pair in the at least one matching pair is determined. Then, a use solution is obtained by computing the matching relationship graph based on a binary graph maximum weight matching algorithm.

Abstract: A method is for determining a wearing state of earphones. The method includes determining an onto-ears event or off-ears event experienced by the earphones on the basis of first data indicating motion of the earphones. The method further includes determining a first wearing state of the earphones on the basis of second data indicating proximity of the earphones to a user's skin. The method additionally includes determining the wearing state of the earphones on the basis of the determined onto-ears event or off-ears event and the first wearing state. This increases the accuracy of detection of the wearing state of the earphones. Based on this more accurately determined wearing state, the earphones can switch appropriately between a low power consumption mode and a normal operating mode, thereby improving the energy consumption of the earphones.
