Abstract: A diagnostic device for determining an out-of-roundness on wheels of rail vehicles within a specified measuring section, comprising a plurality of force sensors, which are designed to determine forces acting on them and are connected to an evaluating device, wherein the evaluating device is provided for determining the out-of-roundness by integrating a force signal F, which is forwarded by the force sensors over time in order to determine an impulse. A method is also provided for determining an out-of-roundness on wheels of rail vehicles within a specified measurement section, wherein the force signals of at least one force sensor are fed to an evaluating device, the evaluating device detects an impulse, and the evaluating device integrates a force signal over a defined time interval and thereafter uses said force signal to output a result.

Abstract: Methods for identifying a vehicle using a predetermined location are provided, as well as a radio beacon and an onboard unit for use with the methods. One method comprises: carrying, on the vehicle, an onboard unit that broadcasts status messages that each indicate a current position of the onboard unit and a radio identifier that changes after each or several status messages; receiving at least one status message in a radio beacon; detecting a location usage of the vehicle by evaluating the status message(s) based on the position(s) indicated therein with respect to the predetermined location; transmitting an identification request from the radio beacon to the onboard unit addressed according to the radio identifier from the status message(s); receiving and conducting a legitimacy check of the identification request in the onboard unit and, if the request is legitimate, transmitting an identification of the onboard unit to the radio beacon.
Abstract translation: 提供了使用预定位置识别车辆的方法，以及用于该方法的无线电信标和车载单元。 一种方法包括：在车辆上携带广播状态消息的车载单元，每个单元指示车载单元的当前位置和在每个或多个状态消息之后改变的无线电标识符; 在无线电信标中接收至少一个状态消息; 通过基于其中相对于预定位置指示的位置来评估状态消息来检测车辆的位置使用; 将来自所述无线电信标的识别请求从所述状态消息发送到根据所述无线电标识符寻址的所述车载单元; 接收并对车载单元进行识别请求的合法性检查，并且如果请求是合法的，则将该车载单元的标识传送到无线电信标。

Abstract: A system and method for providing a call-for-help capability is provided by the invention. The system comprises a central location having a dedicated telephone line having a specified caller identification known to a speakerphone system located in the general location of a person who uses the system for emergency signaling. The person is provided with the speakerphone system and a pendent for generating an emergency signal containing the person's identifier. When received at the central location, a telephone number of the speakerphone system corresponding to the identifier is determined and a telephone call is made on a telephone channel having the specified caller identification. When any call is received by the speakerphone system, its caller identification is examined to determine if the caller identification of the telephone call is the same as the specified caller identification. If so, the telephone line is automatically made to go offhook and the call is directed to a speaker associated with the speakerphone system for hands-free operation. If not, the telephone receiver associated with the speakerphone system is allowed to ring-in in the normal way for manual activation by the person.
Abstract translation: 本发明提供了一种用于提供呼叫功能的系统和方法。 该系统包括具有专用电话线的中心位置，该专用电话线具有位于使用系统进行紧急信令的人的一般位置中的免提电话系统已知的指定呼叫者身份。 该人被提供有免提电话系统和用于产生包含该人的标识符的紧急信号的吊杆。 当在中央位置接收时，确定对应于该标识符的免提电话系统的电话号码，并且在具有指定呼叫者标识的电话信道上进行电话呼叫。 当扬声器系统接收到任何呼叫时，检查其呼叫者身份，以确定电话呼叫的呼叫者身份是否与指定的呼叫者身份相同。 如果是这样，则电话线被自动脱钩，并且呼叫被引导到与免提电话系统相关联的扬声器以进行免提操作。 如果不是，与扬声器系统相关联的电话接收机允许以正常的方式进入，以便人们手动激活。

Abstract: A wayside communications safety station is used along rail lines by passengers in distress or crew members, for routine communications among maintenance personnel, and for communications among emergency services personnel. The system comprises a telephone, connectable to a telephone line, to initiate and receive telephone service, and a plurality of manually actuable switches connected to the telephone to initiate a direct dial telephonic signal. At least one voice powered system jack is connectable through the safety station to a voice-powered communications system. A further manually actuable switch is connectable to a direct current traction power control circuit adapted to supply electrical energy to a train, to selectively actuate the control circuit. A safety station additionally includes ability to reset power to the control circuit.
Abstract translation: 遇险或机组人员乘坐铁路线路，维修人员之间进行常规通信，并在紧急服务人员之间进行通信，沿线通信安全站。 该系统包括可连接到电话线的电话，以启动和接收电话服务，以及连接到电话以启动直拨电话信号的多个可手动开关的开关。 至少一个语音电源系统插孔可通过安全站连接到语音供电通信系统。 另一手动致动开关可连接到直流牵引功率控制电路，其适于向列车提供电能，以选择性地致动控制电路。 安全站还包括将电源复位到控制电路的能力。
