摘要： A tunnel barrier in proximity with a layer of a rare earth element-transition metal (RE-TM) alloy forms a device that passes negatively spin-polarized current. The rare earth element includes at least one element selected from the group consisting of Gd, Tb, Dy, Ho, Er, Tm, and Yb. The RE and TM have respective sub-network moments such that the absolute magnitude of the RE sub-network moment is greater than the absolute magnitude of the TM sub-network moment. An additional layer of magnetic material may be used in combination with the tunnel barrier and the RE-TM alloy layer to form a magnetic tunnel junction. Still other layers of tunnel barrier and magnetic material may be used in combination with the foregoing to form a flux-closed double tunnel junction device.

摘要： One embodiment of the present invention sets forth a technique for streaming digital media content with transition effects. Audio data may be modulated and received by the streaming device for an audio fade-in effect. Similarly, video data may be modulated to perform various visual effects. Such a technique allows for fading-in of audio and/or video, fading-out of audio and/or video, and effects that blend audio from different content and video from different content during a transition from one digital media content to a different digital media content or within the same digital media content. The modulated audio and video data to generate the audio or video effect during a transition may be precomputed or computed in real-time and transmitted to the streaming device. The streaming device switches between original unmodulated content streams and effect content streams when transitions are detected.
摘要翻译：本发明的一个实施例提出了一种用于流式传输具有过渡效果的数字媒体内容的技术。音频数据可以被流式传输设备调制和接收，以实现音频淡入淡出。类似地，可以调制视频数据以执行各种视觉效果。这种技术允许在从一个数字媒体内容到另一个数字媒体内容的转换期间，音频和/或视频的淡入淡出，音频和/或视频的淡入淡出以及混合来自不同内容的不同内容和视频的音频媒体内容或同一数字媒体内容内。用于在转换期间产生音频或视频效果的调制音频和视频数据可以被预先计算或实时计算并被发送到流传输设备。当检测到转换时，流设备在原始未调制内容流之间切换并影响内容流。

摘要： One embodiment of the present invention sets forth a technique for starting playback of an audio portion of digital media content before a video portion of the digital media content is received. An advantage of the disclosed technique is that the perceived delay from the time when a user selects the digital media content to when playback of the digital media content begins is reduced. The audio may be faded-in and one or more still frames of video data may be displayed while the video stream is retrieved. Additionally, a license for DRM (Digital Rights Management) encryption of the title content may be retrieved before starting playback of the video stream, so that the digital media content that is retrieved is also protected.
摘要翻译：本发明的一个实施例提出了在数字媒体内容的视频部分被接收之前，开始重放数字媒体内容的音频部分的技术。所公开技术的优点在于，从用户选择数字媒体内容的时间到数字媒体内容的播放开始时的感知延迟被减少。音频可以是淡入的，并且在检索视频流时可以显示视频数据的一个或多个静止帧。此外，可以在开始重放视频流之前检索标题内容的DRM（数字版权管理）加密的许可证，从而也检索被检索的数字媒体内容。

摘要： A method and system for providing a magnetic transducer are disclosed. The method and system include providing a magnetic element including a free layer, a nonmagnetic spacer layer, a pinned layer, and a pinning layer adjacent to the pinned layer. The free layer is to be biased in a first direction. The pinning layer biases the pinned layer magnetization in a second direction. The pinning layer is oriented along the second direction. A hard bias structure is adjacent to the magnetic element. The hard bias structure magnetization is initialized such that it has a nonzero component along the second direction. The method and system also include performing thermal treatment(s) after initializing the hard bias magnetization. The thermal treatment(s) are above room temperature. The method and system further include resetting the hard bias magnetization substantially along the first direction after the thermal process(es) are performed.
