Abstract: A control method includes obtaining an active time set in a predetermined time period that includes an active time instance at which a human body sensor assembly of a dishwasher detects human body activity in a predetermined region of the dishwasher, obtaining operation time of the dishwasher in the predetermined time period, predicting a tableware taking-out time point based on the active time set and the operation time, and controlling, at a target time point, the dishwasher to perform odor removal processing. The target time point is at a time length before the tableware taking-out time point.

Abstract: A data storage method and apparatus, and a data read method and apparatus in order to resolve a technical problem that a data storage process is relatively complex. The data storage method includes receiving to-be-written first data in a first format from an application layer, obtaining a first mapping relationship between data in the first format and data in a second format, where the second format is a KeyValue format, and the first mapping relationship is used to indicate a row attribute and a column attribute corresponding to each value obtained by converting the data in the first format, converting the format of the first data into the second format according to the first mapping relationship in order to obtain second data, and storing the second data.

Abstract: The present invention relates to a low-inductance electromagnetic drive without driving magnetic flux circuit, which comprises a magnetic pole, a drive coil, an upper magnetic inductive board, a permanent magnet and a lower magnetic-inductive board. The magnetic pole is integrated with the lower magnetic-inductive board, and the permanent magnet is located between the upper magnetic-inductive board 4 and lower magnetic-inductive board 6. The drive coil is wrapped around the magnetic pole and is movable in the axial direction. The electromagnetic drive further comprises the fastening coil, and the fastening coil is fastened to a certain proper place of the magnetic flux circuit of the drive coil. Furthermore, the fastening coil is connected with the drive coil in opposite phase.
