摘要： A method for detecting errors in a processing device is disclosed. A data source unit of a processing device transmits data and a qualifier synchronously with the data, the qualifier to indicate the data is uncorrectable. At least one intermediate functional unit in the processing device receives the data and the qualifier. The at least one intermediate functional unit detects the data is uncorrectable based on the qualifier. The at least one intermediate functional unit transmits, without using, the data and the qualifier synchronously with the data to a data consumer unit of the processing device. The data consumer unit receives the data and the qualifier. The data consumer unit detects the data is uncorrectable based on the qualifier. The data consumer unit maintains, without using the data and the qualifier.

摘要： A modular multi-service telecommunication access device includes a controller card and card slots for six peripheral cards and a power supply. Any of several types of peripheral cards can be inserted into the six card slots. A card present/protocol scheme allows an inserted card to recognize its address and communicate same as well as its communication protocol to the controller card via a PCM highway. The controller card sends both signaling information and management information to the peripheral cards via another PCM highway. A unique communication protocol allows for both real time signaling information and non-real time management information to be sent on the same channel. A microprocessor on the controller card includes an algorithm for managing messages to the various peripheral cards in the various card slots. A unique tributary addressing scheme allows for a simplified address used by external users to be converted to a more detailed internal address. A battery sense circuit includes a variable resistive element used in conjunction with additional circuitry to sense conditions relevant to the battery. A unique ringer circuit includes a boost converter for producing a sufficiently high voltage for the circuit. A faceplate provided on each of the circuit cards has resilient fingers thereon for selective mating with the chassis of telecommunication device.

摘要： A method for reliably measuring preformatted servo patterns, on a magnetic tape, for positioning a magnetic head. The tape has constant frequency stripes marking servo pattern areas. The drive reading the preformatted tape has a read channel amplifier with automatic gain control (AGC). When a stripe is detected, AGC is enabled. Before leaving a stripe, AGC is placed on hold. The amplitudes of two servo bursts are then measured with a gain that has been calibrated by a signal from a stripe. During the time AGC is enabled, the amplifier peak output is limited to less than half the maximum amplifier peak output. The servo pattern signal amplitude is about twice the signal amplitude of a stripe, so that servo patterns are measured with almost the maximum signal-to-noise ratio. When a stripe is detected, a counter counts pulses resulting from the stripe signal, for a fixed time, to ensure that the stripe detection is valid. If the stripe is qualified, the servo pattern measurements are used for head alignment adjustment. If the strip is not qualified, the servo pattern measurements are discarded.
摘要翻译： 一种在磁带上可靠地测量用于定位磁头的预格式伺服图案的方法。 磁带具有标记伺服图案区域的恒定频率条纹。 读取预格式化磁带的驱动器具有带有自动增益控制（AGC）的读通道放大器。 检测到条带时，启用AGC。 在离开条纹之前，AGC被置于保持状态。 然后用已经通过条带的信号校准的增益来测量两个伺服脉冲串的振幅。 在启用AGC的时间内，放大器峰值输出被限制为小于最大放大器峰值输出的一半。 伺服模式信号幅度约为条纹信号幅度的两倍，从而以几乎最大的信噪比测量伺服模式。 当检测到条纹时，计数器对条带信号产生的脉冲计数一定时间，以确保条形检测有效。 如果条纹合格，则使用伺服模式测量来进行头部对准调整。 如果条带不合格，则丢弃伺服模式测量。

摘要： A circuit and method for generating write compensated write data signals in magnetic data recording. The circuitry is programmable to enable generation of write compensation meeting a variety of write compensation specifications. In particular, the circuitry can be programmed to generate extra write pulses, to adjust the pulse width and to adjust the pulse spacing within data cells. In an example embodiment, an input waveform drives a reset input on a state machine. An output waveform shape is stored as a pattern of bits in a register. The state of the state machine determines which register bits are selected by a multiplexer for output as a new write compensated write data signal.
