摘要： A system for receiving and processing digital video information such as a digital television broadcast, includes a modular platform which receives a plurality of hot pluggable cards. The platform is coupled by a high data rate graphics bus to a digital television display. The bus may provide encrypted information to prevent piracy of the video. Because the platform is modular in design, upgrades to the digital video system may be easily implemented using hot pluggable technology without changing the display. Thus, advances in electronics may be incorporated into the platform without necessitating that the owner replace the display.
摘要翻译：用于接收和处理诸如数字电视广播的数字视频信息的系统包括接收多个热插拔卡的模块化平台。该平台通过高数据速率图形总线耦合到数字电视显示器。总线可以提供加密信息，以防止视频的盗版。由于该平台采用模块化设计，因此可以使用热插拔技术轻松实现对数字视频系统的升级，而无需更改显示。因此，电子设备的进步可以并入平台中，而不需要所有者更换显示器。

摘要： A marking device is provided. The marking device (MD) includes an elongated housing that has a tip configured to contact a surface. The MD also includes a pressure sensor disposed within the housing. The pressure sensor is coupled to the tip and is configured to detect when the tip contacts the surface. The MD further includes first and second acceleration sensors disposed within the housing and adjacent the tip of the MD. The first and second acceleration sensors are configured to sense acceleration of the tip in first and second directions. Responsive to the sensing of acceleration, first and second acceleration sensors generate a signal indicative of acceleration in first and second directions. The MD also includes a conversion device configured to receive first and second signals and convert first and second signals into at least one computer readable signal.
