A method and apparatus for transferring AC electrical power to a load from a first power source to a second power source provides for a time delay in the transfer to avoid problems associated with differences in the phases between the power sources. The phase of the voltage waveform from each power source is sensed continuously, and the phase difference is known at all times, so that it can be used when the transfer is necessary. The method and apparatus monitors the voltage from the first power source, and initiates the transfer from the first power source to the second power source in response to an unacceptable condition from the first power source. The second power source is connected only after waiting for a period of time corresponding to the appropriate time delay. By avoiding instantaneous transfers and providing for a delay in the switching to a secondary power source, the present invention avoids the problems associated with transformer saturation, and the resulting draw of a large amount of current from the power source that can cause upstream circuit breakers to trip open, and uninterruptible power systems and engine generators to malfunction.

The invention relates to a device for improving the visibility conditions in a motor vehicle, having a radiation source for infrared radiation for irradiating the surroundings of the vehicle, having an infrared-sensitive camera for taking images of at least part of the irradiated surroundings, having a display unit for displaying collected image data, and having a control unit for controlling the device. In this context, the control unit is embodied in such a way that, while the device is operating, the display represents image data in a chronologically limited fashion by means of controlled switching on and switching off, and in the process the switching off of the representation of images on the display is made gradual. The gradual switching off is carried out in particular by changing the brightness limiting values, the contrast limiting values and / or by increasing or reducing the noise of the image data to be represented. Furthermore, the gradual switching off preferably has a time-dependent or velocity-dependent profile. This device ensures that the vehicle with the device operates in a very safe way for the user.

Transmitting data in a ring network that transmits bursts and data packets. A path setup message is sent to request a data transmission between a source node and a destination node j through intermediate nodes connecting the source node and the destination node j. Each intermediate node determines that a connection to a next node along the path is available when the connection to the next node, that normally transmits bursts and data packets, transmits data packets. A current data transmission of data packets on the path is stopped when the entire path is determined to be available.

The overcenter assembly further has a center position located between the engaged and disengaged positions. The pivot trajectory between the center position and the disengaged position is divided into a tensioned section in which the end stop does not engage the stop surface and the spring exerts a force on the overcenter assembly, and a free-moving section in which the end stop engages the stop surface and the spring does not exert any force on the overcenter assembly.

The amount of simultaneous switching noise generated through the operation of a programmable device can be reduced by reducing the number of pins switching at the same time. An I / O bank can include a number of I / O pin subsets, or DQS groups, each programmed to switch at a different time so that the switching times of the various pins can be staggered for each system clock cycle. Programmable delay elements can be used to control the delay of each subset. The programmable elements can be placed between the system clock and the output registers in order to delay the receiving of the clock signal by the registers and therefore delaying the switching of the output buffers. The programmable delay elements also can be placed between the output registers and the output buffers in order to delay the receiving of the output data by, and subsequent switching of, the output buffers.
