    • A decoder is described that comprises first terminals (21a, 21b) suitable to receive a codified start signal (31) coming from a control unit (9), means (32) for decoding the start signal, programmable controller means (34, 50) provided with memory and startable by the decoded start signal (33), signal generating means (51, 52) controlled by said controller means (34, 50) in such a way so as to generate a control signal (60) in alternate current in order to turn on and off at least one solenoid in alternate current (15,..., 17) for the operation of a solenoid valve. The control signal (60) comprises an initial pulse (70) for the start of the solenoid and a plurality of pulses (71) with prefixed cadence for the maintenance of the solenoid in the ON state. The initial start pulse (70) has a certain voltage value (V1) and a certain duration (T1) and each one of said maintenance pulses (71) has equal voltage value but duration (T2) shorter than said start pulse (70). The programmable controller means (50) control said signal generating means (51, 52) so that the control signal (60) provides the repetition of said initial start pulse (70) and said maintenance pulses (71) with prefixed cadence (T) for a predetermined number of times.
    • 描述了一种解码器,其包括适于接收来自控制单元(9)的编码起始信号(31)的第一端子(21a,21b),用于解码起始信号的装置(32),可编程控制器装置(34,50) 具有存储器并由解码的起始信号(33)启动,由所述控制器装置(34,50)控制的信号发生装置(51,52)以这样的方式产生交流电流中的控制信号(60) 为了操作电磁阀,交替电流(15,...,17)中的至少一个电磁线圈打开和关闭。 控制信号(60)包括用于启动螺线管的初始脉冲(70)和多个脉冲(71),其具有用于在导通状态下维持螺线管的前置节奏。 初始起始脉冲(70)具有一定的电压值(V1)和一定的持续时间(T1),并且每个所述维护脉冲(71)具有等于电压值,但持续时间(T2)比所述起始脉冲(70)短。 可编程控制器装置(50)控制所述信号发生装置(51,52),使得控制信号(60)以预定节奏(T)提供所述初始起始脉冲(70)和所述维护脉冲(71)的重复, 预定次数。

    • An electronic device such as a medical monitor (1) operates under program control. If any of these programs needs update, or if new programs or test procedures are to be added to the existing programs, an activating circuit such as box (7) containing a microprocessor and a non-volatile memory is connected (cable (8), connector (9), jack (6)) with the electronic device. The microprocessor contained in box (7) executes a program which basically consists of two modules, the first module establishing communication with the electronic device and the second module transmitting activating code, program code or a test code to the electronic device. It is possible either to "download" new programs or to activate programs which already exist in the electronic device. The first module may comprise steps to ensure that box (7) can only be used with one electronic device and further to ensure that a download is only performed if the electronic device has not yet been activated.
    • 诸如医疗监视器(1)的电子设备在程序控制下操作。 如果这些程序中的任何一个需要更新,或者如果新的程序或测试程序被添加到现有程序中,则连接包含微处理器和非易失性存储器的启动电路(7)(电缆(8)), 连接器(9),插孔(6))。 包含在盒(7)中的微处理器执行基本上由两个模块组成的程序,第一模块与电子设备建立通信,第二模块向第二模块发送激活码,程序代码或测试代码到电子设备。 可以“下载”新程序或激活电子设备中已经存在的程序。 第一模块可以包括确保盒(7)只能与一个电子设备一起使用并进一步确保仅当电子设备尚未被激活时才执行下载的步骤。
