摘要： In this patent, a timer-based recording scheme is developed to circumvent the internal delays associated with Flash based media when reading and writing from media such that the low level card access, rather than blocking the processor while writing to or reading from Media, uses a direct-memory-access (DMA) peripheral and then periodic interrupts (using an empirically determined period) to check whether write/read process is completed. If it is completed, then next write/read process is initiated. This process will be repeated until the recording is finished. At a higher level, to record in FAT format, the FAT table and Root Directory table are cached into the processor memory during initialization. Rather than updating those tables in the media, they are updated in processor memory (due to faster access times) while recording. Finally, those tables are written back to the media once recording is finished.
摘要翻译：在该专利中，开发了基于定时器的记录方案，以便在从媒体读取和写入时避开与基于闪存的媒体相关的内部延迟，使得低级卡访问而不是在写入或读取媒体时阻止处理器使用直接存储器访问（DMA）外设然后周期性中断（使用经验确定的周期）来检查写入/读取过程是否完成。如果完成，则启动下一个写入/读取过程。这个过程将重复，直到录制完成。在较高级别，要以FAT格式记录，FAT表和根目录表在初始化期间缓存到处理器内存中。而不是在媒体中更新这些表格，而是在录制时更新处理器内存（由于更快的访问时间）。最后，记录完成后，这些表将被写回媒体。

摘要： A digital radio includes an identification number available only to the digital radio itself. A transmitted band received by the digital radio includes an identification number in an information channel. When the two identification numbers match, then the digital radio performs at least one function included in the information channel or, accesses a preselected procedure. In either situation, the presence of the matching identification number in an information channel results in the execution of instructions causing the digital radio to suspend operation, e.g., by deleting certain files. These digital radio can only be reactivated by the manufacturer, e.g., by the reinstallation of the deleted files. In this manner, the digital radio, being inoperative, is useless to a thief. In addition, one of the activities enabled by the identifying number in the information channel, when the digital radio is installed in a vehicle, can be the disabling of the vehicle.
