  • Publication number: 20190200421
    Abstract: The present disclosure provides a method for controlling a power of an electromagnetic cooking appliance and an electromagnetic cooking appliance. The electromagnetic cooking appliance includes a first coil disk and a second coil disk. Each of the first coil disk and the second coil disk corresponds to an independent resonance circuit. After obtaining a target power of the electromagnetic cooking appliance, a heating period of the electromagnetic cooking appliance is determined based on the target power, each heating period including at least one first heating time period and at least one second heating time period. The first coil disk is controlled to heat in the first heating time period, and the second coil disk to heat in the second heating time period, such that the first coil disk and the second coil disk are heated alternately to reduce an interference of harmonic current and voltage flicker.

  • Patent number: 8743669
    Abstract: An optical disc drive and a method of reading an optical disc are disclosed. The drive includes an I/O port, an optical pickup module and a format conversion unit. The I/O port couples a host to receive a read command of a host terminal file system format. The optical pickup module accesses the optical disc which contains data of a first file system format. The format conversion unit coupled between the I/O port and the optical pickup module includes a mapping information generation module, a memory module and a read-command processing module. The mapping information generation module controls the optical pickup module to access data and thereby to generate mapping information. The memory module stores the mapping information. The read-command processing module controls the optical pickup module to access the optical disc according to the read command by referring to the mapping information.

  • Publication number: 20060285550
    Abstract: An apparatus, system, and method are disclosed for communicating over multiple paths. A reserve interception module intercepts a single-path reserve command from a host. The host-computing environment is configured to issue single-path commands, but is not configured to issue multiple-path commands. A reserve generation module generates a multiple-path reserve command in response to the single-path command. A reserve command module reserves multiple paths between the host and the storage device using the multiple-path command, enabling the host to communicate over multiple paths with the storage device.
