Systems and methods using electrical receptacles for integrated power control, communication and monitoring

An electrical receptacle contains contacts, at least one contact for electrical connection to a hot power line and at least one contact for a neutral power line. A controlled switch, such as a TRIAC, is connected in series relationship between the contact and the hot power line. One or more sensors are provided which detect signals of the hot power line and / or the neutral power line. The processor provides activation or deactivation control to the controlled switch in response to the detected signals that are indicative of conditions relative to the first and second contacts.

Transmitting apparatus and method, and receiving apparatus and method

Image data is encoded to generate encoded data. An encoding-time buffer period that is a minimum buffer period necessary to prevent synchronous reproduction in which the encoded data is decoded and reproduced in synchronization with a timestamp added to the encoded data from failing due to a delay caused by encoding of the image data is added to the encoded data as encoding header information. A transmission-time buffer period that is a minimum buffer period necessary to prevent the synchronous reproduction from failing due to a delay caused by encoding of the image data and transmission of the encoded data is added to the encoded data as transmission header information different from the encoding header information. The encoded data having the encoding-time buffer period and the transmission-time buffer period added thereto is transmitted to another apparatus that performs the synchronous reproduction via a network.

Extending achievable duty cycle range in dc/dc forward converter with active clamp reset

Novel system and methodology are provided for controlling a DC / DC forward converter having a transformer with primary and secondary windings, a reset switch, and a first switch coupled to the primary winding of the transformer. The control system involves a PWM control circuit responsive to an output signal of the converter for producing a PWM signal to control switching of the reset switch, and the first switch. A period of the PWM signal includes an on-time interval for enabling transfer of power via the transformer when the first switch is on, and a reset time interval for enabling reset of the transformer when the reset switch is on. A maximum value of the on-time interval is pre-set to provide sufficient time for the reset. The reset switch is turned off when the PWM signal goes from a first level to a second level. A first delay period is set between time when the reset switch turns off and time when the first switch turns on. A first delay control circuit is provided for reducing the first delay time when the on-time interval approaches the maximum value. Further, the converter may include a second switch coupled to the secondary winding of the transformer. A second delay period shorter than the first delay period may be set between time when the reset switch turns off and time when the second switch turns on. A second delay control circuit may be provided for reducing the second delay period when the on-time interval approaches the maximum value.

Optical disc drive and hibernation recovery method for an optical disc drive

The invention provides an optical disc drive and hibernation recovery method for the optical disc drive, capable of preventing a time-out from occurring on a host computer when a second command is received before writing is completed after the optical disc drive receives a write request and recovers from a hibernate state. Provided is a technology in which a controller for controlling read/write performed to/from an optical disc includes a processor for controlling an interface, a temporary memory unit, a rotation control unit, and an optical control unit. The controller causes the processor to shift to a hibernate state when a predetermined condition is satisfied, and causes the processor to recover from the hibernate state into an active state when the interface receives a first command. The processor receives the first command from the interface, instructs the rotation control unit to drive the optical disc at a predetermined target rotational speed, instructs the optical control unit to perform a processing specified by the first command, transmits a completion notification of the first command to the interface with a delay, receives a second command after transmitting the completion notification of the first command, and executes the processing of the second command.
