Control of consumption of media objects
A method and mechanism controls consumption of media objects in a communication terminal, especially in a mobile terminal. A media object, such as a game, and an associated rights object are stored in a communication terminal. The rights object defines usage rules for the media object. Sales parameters are accepted from a user of the terminal. The sales parameters indicate that the user is willing to sell the rights of consumption of the media object to a certain extent. Upon receiving this indication, the media object is prevented from being consumed in the communication terminal more than what is defined by the usage rules and the certain extent. A sell offer may then be transferred to a trading entity. |

Sliding window block codes for cross-packet coding
A block-code-based structure that allows cross-packet coding of data using a sliding window. In this structure, each transmitted packet contains both information symbols and parity symbols generated by the information in previous packets. This code structure allows a receiver to recover lost packets without additional transmissions. If enough packets have been lost so that the receiver cannot recover one or more of them, new parity symbols can be generated and transmitted as additional packets. The parity symbols in these additional packets may be used by multiple receivers. Thus, the sliding window block code reduces retransmission overhead, particularly for multicast applications. Furthermore, the sliding window structure does not produce an encoding delay between the arrival of data and its transmission and reduces the decoding delay between the loss of a packet and its recovery. |

If the error correction code decode process when completed indicates an error in the given retrieved word, the error in the given retrieved word is corrected in the error correction circuitry, and the error correction code encode process is restarted using the corrected word. The error correction code decode process and an associated correct process are thereby removed from a critical timing path of the partial word write operation. |

Circuit for boosting encoding capabilities of test stimulus decompressors
The circuit for boosting encoding capabilities of test stimulus decompressors is utilized in conjunction with a stimulus decompressor. The circuit, called align-encode is inserted between the decompressor and internal. The scan chains feed into a response compactor.

Re-configurability of the align-encode circuit allows for this manipulation via delay cells with the align-encode circuit, whose length can be adjusted on a per scan chain per test pattern basis by loading the align-encode circuit with proper control data. Based on the stimulus decompressor characteristics, the scan chains are delayed in such a way that an unencodable pattern becomes encodable when using the align-encode circuit. |

Channel mechanisms for communicating with a processor event facility
Mechanisms for communicating with a processor event facility are provided. The mechanisms make use of a channel interface as the primary mechanism for communicating with the processor event facility. The channel interface provides channels for communicating with processor facilities, memory flow control facilities, machine state registers, and external processor interrupt facilities, for example. These channels may be designated as blocking or non-blocking. With blocking channels, when no data is available to be read from the corresponding registers, or there is no space available to write to the corresponding registers, the processor is placed in a low power “stall” state. The processor is automatically awakened, via communication across the blocking channel, when data becomes available or space is freed. Thus, the channels of the present invention permit the processor to stay in a low power state. |

Apparatus and method for controlling audio-frame division
To alleviate degradation of sound quality which may be caused by pre-echoes and bit starvation. An acoustic analyzer analyzes an audio signal to calculate perceptual entropy indicating how many bits are required for quantization.

An orthogonal transform processor divides a frame by the determined division number and subjects each divided block of the audio signal to an orthogonal transform process, thereby obtaining orthogonal transform coefficients. A quantizer quantizes the orthogonal transform coefficients on a divided block basis. |

Method for run-length encoding of a bitmap data stream
Subtitling aims at the presentation of text information and graphical data, encoded as pixel bitmaps. The size of subtitle bitmaps may exceed video frame dimensions, so that only portions are displayed at a time. The bitmaps are a separate layer lying above the video, e.g. for synchronized video subtitles, animations and navigation menus, and therefore contain many transparent pixels. An advanced adaptation for bitmap encoding for HDTV, e.g. 1920.times.1280 pixels per frame as defined for the Blu-ray Disc Prerecorded format, providing optimized compression results for such subtitling bitmaps, is achieved by a four-stage run length encoding. Shorter or longer sequences of pixels of a preferred color, e.g. transparent, are encoded using the second or third shortest code words, while single pixels of different color are encoded using the shortest code words, and sequences of pixels of equal color use the third or fourth shortest code words. |

Selective multicast traffic shaping
A method and integrated hardware system for multicast transmission shaping in EPONs which employs a selective multicast algorithm that significantly reduces the complexity of traffic shaping for multicast traffic. Unlike prior art methods, my method exploits the broadcasting nature of the downstream point-to-multipoint access system including EPONs. Operationally, the method transforms a multicast traffic shaping problem into a unicast traffic shaping problem by selecting a multicast subscriber and subsequently treating packets addressed to that selected multicast subscriber as unicast. Advantageously, these packets are still available to other members of the multicast group. And since these packets are treated as unicast from the perspective of traffic shaping, my inventive method significantly reduces traffic shaping complexity in multicast environment. |

A thin film magnetic head includes: a reproducing element; a recording element that is formed on the reproducing element; a heater that is supplied with power and generates heat to expand at least one of the reproducing element and the recording element such that the reproducing element and/or the recording element protrude toward a recording medium; and a temperature correcting resistor that is connected in parallel to the heater and has a negative resistance temperature coefficient. |

Magnetic head inspection system, magnetic head inspection method and magnetic disk drive manufacturing method
Embodiments of the present invention provide a magnetic head inspection system having a simple configuration capable of inspecting magnetic heads. According to one embodiment, the magnetic head inspection system comprises an inspection module which is provided with a magnetic disk where servo data including track identifier information are recorded, a spindle motor, a carriage having a mount structure to which a head assembly containing a magnetic head is secured, a voice coil motor and a main circuit section. An inspection circuit section instructs the main circuit section to execute control so as to move the magnetic head to a specific track and perform a certain read write operation by the magnetic head in order to inspect the magnetic head. |

Disk drive device and carriage of actuator with damping member
Embodiments of the present invention help to suppress performance degradation in an actuator of a disk drive device when attaching a damping member to a single surface of an arm. According to one embodiment, in a HDD a damping member is attached to a single surface of an arm. A shape of an inner arm is asymmetric with the center position between disks. Specifically, the thickness from a center position between the disks to the damping material attaching surface is thinner than the thickness from a center position between the disks to an opposite surface of the damping member attaching surface. This suppresses deformation of the vibration mode in the case that the damping member is attached to the single surface of the arm. |
