摘要： A method of calibrating signal processing circuitry in a magnetic data storage device. The method ensures that an adequate signal-to-noise ratio is achieved when reading a head-position calibration signal. First, discrimination thresholds are set to an initial low value. Then, with wide bandwidth and stationary media, amplifier gain is calibrated by adjusting gain to make the amplitude of amplified background noise equal to the initial threshold value. Finally, bandwidth is reduced and the discrimination thresholds are raised to a final value. The final threshold value ensures that a signal must exceed a predetermined signal-to-noise ratio before the signal is accepted as being valid.

摘要： An apparatus and method for generating an index pulse by a data storage tape drive. The tape drive is controlled by a flexible disk controller. A multi-track tape is formatted into multiple data segments per track with erased areas between segments. A digital data signal from the tape signal processor is sampled to detect a lapse in data. Then, the analog data signal is continuously monitored to detect the reappearance of data. When filtered analog signal peaks exceed a fixed threshold, a pulse is generated from the tape drive to the flexible disk controller. In an alternative embodiment, to further protect against false triggering, index pulse generation is suppressed during most of each erased area between segments. In another embodiment, index pulse generation is suppressed if an erased area exceeds a length threshold, such as at the end of the tape. In still another embodiment, index pulse generation is suppressed if digital data reappears without triggering the analog monitoring circuit.
摘要翻译：一种用于通过数据存储磁带驱动器生成索引脉冲的装置和方法。磁带驱动器由一个软盘控制器控制。多轨磁带被格式化为每个轨道的多个数据段，并且段之间具有擦除区域。来自带信号处理器的数字数据信号被采样以检测数据中的经过。然后，连续监视模拟数据信号，以检测数据的再现。当滤波模拟信号峰值超过固定阈值时，会从磁带驱动器到软盘控制器产生脉冲。在替代实施例中，为了进一步防止错误触发，在片段之间的每个擦除区域的大部分期间抑制索引脉冲生成。在另一个实施例中，如果擦除区域超过长度阈值，例如在磁带末端，则抑制索引脉冲产生。在另一个实施例中，如果数字数据重新出现而不触发模拟监视电路，则抑制索引脉冲产生。

摘要： A method for reducing motor start-up current in an electric motor control system. The method first prevents flow of current through the motor while slowly charging a parallel capacitor. Then, the motor control voltage is reduced and current is switched through the motor. The motor control voltage remains reduced until the motor starts turning. After the motor starts turning, the control voltage is slowly increased as the motor accelerates, limiting the current from the power supply.

摘要： A transparent disposable coffee cup used for dispensing coffee by coffeehouses and the like is disclosed. Measurement markings are formed on an interior surface of the cup adjacent the mouth. The measurement markings are identify different fill lines which relate to the amount of milk or cream that the consumer wishes to add to the coffee. Depending on the cup size two or more additional raised markings are provided. These marking are located below the top fill line and may optionally represent the space to add a certain percentage of cream. For 12 ounce cups, the markings may be located at levels equivalent to one ounce of cream and two ounces of cream. In accordance with an important aspect of the invention, the raised markings can be made on an interior surface of the cup by automated manufacturing methods.
