A power supply system includes a coupling device including a power conversion device, and one or more power supply units. Each of the power supply units includes a distributed power supply, a first interface outputting DC power to the power conversion device, an individual converter converting the DC power to AC power, and a second interface outputting the AC power output from the individual converter. The power conversion device includes a coupling side converter that converts the direct current power output from the power supply units to AC power, and an interface for outputting the AC power output from the coupling side converter. The power supply system includes a controller for controlling at least one of a corresponding one of the power supply units or the power conversion device based on communication information obtained by communication between the corresponding one of the power supply units or the power conversion device.

Power supply system, coupling device, power supply unit, and control method

Power is generated efficiently using fuel. A power generation unit includes a power generation module that generates power using fuel, a supply unit that supplies fuel to the power generation module, a power converter that converts DC power supplied by the power generation module into AC power, and a controller that controls the supply unit and the power converter. The controller controls the supply unit or the power converter so that the output power supplied to a load with fluctuating power consumption becomes greater than the power consumption of the load by a predetermined margin.

Power generation unit and control method of the same

A power supply apparatus links to a grid, converts DC power from a distributed power source to AC power, and includes a controller that controls input voltage of the DC power in accordance with current flowing between the power supply apparatus and the grid. Based on communication with another power supply apparatus connected to the power supply apparatus, the controller also sets a standard value of controlling the input voltage.

A power generation control apparatus () includes a solar cell controller () and a range determinator (). The solar cell controller (), while changing at least one of an operation current and an operation voltage serving as driving variables within a first range, calculates actual power generated by a solar cell (). The solar cell controller () controls the solar cell () to generate power by using a driving variable that maximizes the generated power within the first range. The range determinator (), based on maximum generated power and at least one of a rated PV curve or an approximation line of the rated PV curve and a rated PI curve or an approximation line of the rated PI curve, updates the first range.

A portable terminal includes a page storage section, in which a Web page is temporarily stored while the Web page is being browsed. Thus, when the same Web page is browsed the next time, a control section compares the Web page with the previously stored page contents and moves the display range of the page, so that the updated portion is displayed at a predetermined position on a display section.

Display apparatus

A display apparatus comprises: a display unit in which each pixel is formed from a self-luminous element, and a controller that reduces a luminance of a pixel which has not changed for a predetermined period of time or more.

Display apparatus having luminance reduction controller

A transmitting apparatus comprises an initialization vector generating unit for generating an initialization vector, an encryption unit for initializing a stream encryption module using the generated initialization vector and performing stream encryption on stream data using the initialized stream encryption module, an encryption packet generating unit for generating an encryption packet containing encrypted stream-encrypted data, an initialization packet generating unit for generating an initialization packet containing an initialization vector and time information indicating when a next initialization vector subsequent to the initialization vector will be sent, and a transmission unit for transmitting the initialization packet and the encryption packet by broadcast/multicast.

Content data, transmitting apparatus, receiving apparatus and decoding method

An information processing apparatus () is provided with a memory unit () for storing digital broadcast content for which a number of copies that can be made is set, a writing unit () for writing the content on external recording medium, an IC medium reader/writer () for reading an IC medium () and recording the number of copies that can be made of the content on the IC medium () in association with an identifier of the content, and a control unit () for determining whether an identifier of the content is recorded on the IC medium () when the content is copied to the external recording medium and, when it is determined that the identifier is recorded, controlling the writing unit () to write the content on external recording medium () as well as controlling the IC medium reader/writer () to update the number of copies that can be made of the content.

Information processing apparatus

A reception apparatus in accordance with the present invention is provided with a reception unit () to receive a stream including a data signal, a display unitfor performing display based on the stream received, an authentication process unitfor authenticating a sender of the stream received, a signal separating unitfor separating the data signal from the stream received, a script detection unitfor detecting a script by analyzing the data signal separated, and a control unitfor controlling the display unitto perform display based on the stream received, wherein the control unitprohibits an input related to execution of the script in a case where the script is detected by the script detection unitduring an authentication of the stream. Thereby, the reception apparatus plays contents appropriately without inflicting either a disadvantage or stress on a user.

Reception apparatus

By calculating a channel selection frequency on the basis of a channel selection time list in a memory, a control section automatically judges a zapping operation by a user, and performs display of a program list in which all programs being broadcasted are listed.
