摘要： A method and apparatus for calibrating an analog equalizer in a sampled amplitude read channel is disclosed wherein the filter's frequency response is measured and calibrated directly. This is accomplished by injecting a known periodic signal into the analog filter and measuring a spectrum value at a predetermined frequency. The filter parameters are adjusted accordingly until the spectrum reaches a predetermined target value. In the preferred embodiment, the analog filter comprises at least one second order low pass filter (referred to as a biquad filter), and the filter's spectrum is adjusted relative to the well known parameters f.sub.o and Q. Specifically, the parameters f.sub.o and Q are optimized relative to a power measurement at predetermined harmonics of the input signal. In this manner, the present invention enables auto-calibration of the analog equalizer without reading any data from the disc. Furthermore, the calibration process can be executed during the storage system's normal operation without significantly degrading its overall performance.

摘要： A general-purpose, single-pass, adaptive, and lossless data compression invention implements an LZ1-like method using a hash-based architecture. It is suitable for use in data storage and data communications applications. Implementation efficiency, in terms of required memory and logic gates relative to the typical compression ratio achieved, is highly optimized. An easy-to-implement and quick-to-verify hash function is used. Differential copy lengths may be used to reduce the number of bits required to encode the copy-length field within copy tokens. That is, if multiple matches to a sequence of input bytes are found in the current window, then the length of the copy may be encoded as the difference between the lengths of the longest and the second-longest match, which results in a smaller copy length which likely has a shorter encoded representation. To further increase the compression achieved, literals are not used, but rather input bytes without window matches are mapped into alphabet tokens of variable length using a unary-length code. Other unary-length codes are used to represent the copy-length field and the displacement field within copy tokens.
摘要翻译：通用，单通，自适应和无损数据压缩发明使用基于散列的架构来实现类似LZ1的方法。适用于数据存储和数据通信应用。相对于实现的典型压缩比，在所需存储器和逻辑门方面的实现效率被高度优化。使用易于实现和快速验证的散列函数。差分复制长度可用于减少在复制标记中编码复制长度字段所需的位数。也就是说，如果在当前窗口中找到与输入字节序列的多个匹配，则可以将副本的长度编码为最长和最长匹配的长度之间的差，这导致较小的副本长度可能具有较短的编码表示。为了进一步增加实现的压缩，不使用文字，而是使用一字代码将不带窗口匹配的输入字节映射到可变长度的字母表中。其他一元长度代码用于表示复制标记中的复制长度字段和位移字段。

摘要： A method for inserting a lead electrode into body tissue using a rotatable lead introducer is described. The introducer can include a distal element for releasably engaging a lead head controllable from a proximal control located outside of the body. An inner stem can extend between a proximal portion and a distal portion, and be pivotally and rotatably coupled to the distal lead engagement mechanism. An outer tube can be rotatably disposed over the inner stem and be flexibly coupled over the pivot to rotationally drive the distal element. A helical epicardial-myocardial lead electrode can be secured and oriented straight ahead and introduced through a port or small incision with the introducer in a straight configuration. The introducer can then be bent and rotated to screw the helical electrode into the heart.
