The disclosure relates to a security method for gaining access, which allows authorized persons to gain access to a protected area and prevents access by unauthorized persons. The method is characterized in that a number of persons in a verification area are determined, a number of authorization passes present in said area are verified, the number of persons and the number of authorization passes are compared and if the number of persons agrees with the number of authorized passes, an access approval signal is generated. The disclosure also relates to a device that is suitable for carrying out the method and for an elevator equipped with such a device.

A method and a device for securing objects that are present in protected spatial areas, whereby the objects to be secured are provided with an identifier or linked with an identifier and said identifier is detected by a receiving unit when the object to be secured is displaced. For this purpose, the receiving unit detects the presence of the identifier and electronic data for proving the presence of the identifier are stored. The electronic data are adapted to allow an unambiguous assignment of the signal detected by the receiving unit to the identifier. Data are detected independently of the detection of the identifier that allow an identification of a person carrying an object to be secured.

In a torque transmitting torsional vibration damper device for use in a torque transmission path of a motor vehicle between the engine and the gear box a central plate is provided. Two sides plates are provided on both sides of the central plate. The side plates are interconnected for common rotation. Each of the central plate and the side plates is provided with at least two circumferentially extending windows. Respective windows of the central plate and the side plates are aligned in axial direction. Each group of mutually aligned windows receives a pair of torque transmitting compressional springs arranged in series and spaced in circumferential direction. Said discs are provided between the central plate and the side plates. These sides discs are used for circumferential torque transmission between mutually adjacent ends of the compressional springs of each pair. The side discs are supported in radial direction only by engagement with the compressional springs.

The invention relates to an outdoor lighting unit for lighting streets, pavements, industrial grounds, and the like, comprising one LED light source which includes several light emitting diodes in a two-dimensional array, and a housing. The housing has a single-piece solid housing element, which has at least one planar assembly section on an underside, on which a backside of the LED light source is arranged in heat-conducting connection in a planar manner. The housing element further has on said underside a circumferential wall section, which projects downwardly from the plane of the assembly section. Further, the housing element comprises an exposed cooling section on an upper side, which is convexly curved and has several cooling channels, which extend along the convex curvature. The housing element also comprises a holding portion, by means of which the lighting unit can be secured to a holding device in a self-supporting manner.

A steam power unit including a double-flow medium pressure turbine section that is fluidically connected to a low pressure turbine section is provided. A flow section of the medium pressure turbine section is configured to supply an external steam consumer. A throttle valve for adjusting the pressure in the steam extraction line is arranged only in a turbine discharge line.

A method for operating a multi-step steam turbine operating in high temperature conditions is provided. The rotor is embodied as a welded construction including a first component and a second component. A coolant is supplied to the steam turbine after an intermediate state when the steam turbine is in the light-load or no-load phase. As a result, the thermal loads in the outflow area of the steam turbine are reduced.

The invention relates to a method for increasing the steam mass flow of a high-pressure steam turbine of a steam power plant, particularly a steam power plant including reheating, during a start-up phase of the steam power plant, particularly also during an idle period of the steam power plant, wherein at least one electric consumer is connected upstream of a generator of the steam power plant before synchronization with a power supply grid. The invention further relates to a steam power plant, comprising a generator, a high-pressure steam turbine, and at least one electric consumer, which can also be connected during a start-up phase of the steam power plant, particularly also during an idle period of the steam power plant, in order to increase a steam mass flow of the high-pressure steam turbine before a synchronization process of the generator with a power supply grid.

摘要:
The invention is a method for monitoring an environment by evaluating an infrasonic signal obtained from said environment. The method includes averaging said infrasonic signal (Vinfra) to provide an averaged infrasonic signal (Vav), mapping said averaged infrasonic signal (Vav) according to a function to provide an infrasonic noise signal (Vnoise); averaging said infrasonic noise signal (Vnoise) to provide an averaged infrasonic noise signal (Vav noise); offsetting said averaged infrasonic noise signal (Vav noise) with an offset value to provide an infrasonic level signal (Vlimit); comparing said infrasonic level signal (Vlimit) with said averaged infrasonic signal (Vav); and generating a trigger signal (30) if said averaged infrasonic signal (Vav) is greater than said infrasonic level signal (Vlimit).
