    摘要: A remote measurement unit for testing and conditioning one or more telephone lines includes multiple electronically erasable flash memory banks, which contain respective versions of the operating system employed by the test unit's micro-controller. An operating system modification routine employed by the host processor of a remote site allows the functionality of the remote test unit to be selectively modified by electronically installing an upgraded or downgraded version of the operating system, or by electronically selectively activating or deactivating one or more operational features of the currently active operating system. A reset routine ensures that the operating system modification mechanism will only boot up the `correct` one of the two quasi-redundant systems available to the RMU's microcontroller after a system modification has been performed. In addition, the temporary insertion of a no-op code field just prior to the beginning of the program prevents the RMU's processor from accidentally booting up a modified system until the system has been verified as operational.

    摘要: A processor-controlled integrated telephone line measurement and conditioning apparatus installable at a remote site provides a multiplicity of measurement and conditioning functions that are selectively executable in response to commands issued from a supervisory command site. The dual measurement and conditioning capabilities of the architecture of the present invention impart both remote measurement unit (RMU) functionality and metallic access unit (MAU) functionality that may be individually accessed and controlled. The RMU operates primarily as a test head that performs mechanized loop testing (MLT) tasks, while the MAU is operative to impart prescribed electrical conditions to a specified line circuit. When controllably accessed to operate as an RMU, the present invention responds to instructions from a command site (loop maintenance operations systems) and performs single-line demand tests on a line provided by a pair gain system. To operate as an MAU, the system receives commands from a direct access test unit (DATU) and performs line conditioning functions on the test line provided by the pair gain system.

    摘要: An autobaud detection mechanism, installed as part of the communication control software of a serial communication device's microcontroller, enables the device to automatically determine the baud rate employed by a remote digital data communications device. Starting with a default baud rate, corresponding to the highest available baud rate, the mechanism steps through successively lower baud rates in the course of a search for the baud rate at which the remote device is transmitting. When an incoming call is received, respective bits of the received data are examined for the presence of transmission errors. If a transmission error is detected, the baud rate is stepped to the next lowest baud rate. If no error is detected, the received data bits are compared with a reference character. If the two compared data bit patterns match, the controller locks the baud rate at that baud setting for the remainder of the call. When the call is terminated, the baud rate reverts to its default setting. If the bit pattern comparison does not indicate a match, the baud rate is stepped to the next lowest baud rate. When the autobaud detection routine has stepped to a new baud rate entry, it initiates a prescribed time-out as a safeguard against the receiver becoming `out-of-sync` with a transmitter. Once, the lowest baud rate has been reached, the routine steps to the default setting and starts again.

    摘要翻译: 作为串行通信设备的微控制器的通信控制软件的一部分安装的自动波特率检测机构使得设备能够自动确定远程数字数据通信设备所采用的波特率。 从与最高可用波特率相对应的默认波特率开始,该机制在搜索远程设备正在发送的波特率的过程中逐步降低波特率。 当接收到来电时,检查接收到的数据的各个比特是否存在传输错误。 如果检测到传输错误,则波特率步进到下一个较低的波特率。 如果没有检测到错误,则将接收的数据位与参考字符进行比较。 如果两个比较的数据位模式匹配,则控制器将在该波特率设置下锁定波特率以用于剩余的呼叫。 当呼叫终止时,波特率恢复为默认设置。 如果位模式比较不表示匹配,则波特率步进到下一个最低波特率。 当自动波特率检测程序进入新的波特率条目时,它会启动一个规定的超时,作为防止接收机与发射机“不同步”的保护措施。 一旦达到最低的波特率,例程就会进入默认设置并重新开始。

    摘要: Single pellets of a thermoplastic resin containing long glass fibers and a conductive filler are set forth that enable molded articles made from these pellets to exhibit conductivity and, at the same time, high mechanical properties. These pellets have mechanical properties that are substantially equivalent to non-conductive pellets of a thermoplastic resin containing same loading of long glass and provide conductivity that is substantially equivalent to articles obtained by blending two kinds of pellets, one pellet having a conductive filler and the other pellet one containing long glass fibers. The pellets include a thermoplastic resin, a long fiber reinforcing filler and a conductive additive dispersed in the pellet.

    摘要: A product development technique is provided that enables a user to define a product family design structure. The product family design structure includes a number of customer concerns, a number of physical properties associated with components of the product, and a number of relation models. Each customer concern is associated with at least one physical property via at least one mathematical relationship defined in at least one of the relation models. The technique also enables the user to define one or more product development projects based on the product family design structure, where the one or more product development projects vary from the product family design structure according to one or more overrides specified by the user for the values associated with one or more of the customer concerns, relation models, and/or physical properties defined in the product family design structure. The technique further enables the user to input a value associated with one or more of the physical properties of at least one of the product development projects and to calculate, using one or more of the relation models, the effect of the inputted value associated with the one or more physical properties on one or more of the customer concerns of the product development project.

    摘要: A method of determining an adjusted boost signal includes determining a steady-state boost for a turbocharger (103, 105) for an internal combustion engine (101). The steady-state boost is adjusted (509, 513) for at least one of current transient speed conditions and current transient load conditions of the internal combustion engine, yielding an adjusted boost signal. The adjusted boost signal is sent (517) to the turbocharger.

    摘要: A door phone controller has a door ajar feature for alerting a user that a door was left open. The door phone controller accommodates the door ajar feature in several different ways depending upon how it is configured to interface with the central office line. If the door phone controller is configured to interface with the central office line as an individual station, then when a door is left open, the controller alerts the user via auxiliary alert contacts specifically provided for activating a customer chime. When the door phone controller is configured as a ring-down station, the door phone controller alerts the user that the door was left ajar by dialing a pre-programmed telephone number and sending a door ajar tone. If the door phone controller is configured as an interface with a trunk port, then when the door is left open, the controller alerts the user by ringing the trunk line and also energizing the auxiliary alert contacts. The user can both enable and disable the door ajar features via the telephone interface.
