IPC: G06F13/40
Filed: 2002-12-09
Abstract: A system with a transmitter for transmitting digital data via an interface to a receiver. The interface has at least one data line and a clock line. A clock generator supplies a clock signal to the clock line. The receiver uses the clock signal received from the clock line for deriving timing information for processing received digital data. The clock signal may have an amplitude that is lower than the power supply voltage VDD, typically less than half of the power supply voltage, and less stringent requirements can be applied to the waveform of the clock signal than traditionally applied to data and clock signals. The clock signals are hereby less power consuming and cause significantly less electromagnetic interference.

Abstract: A neutron-optical component array in which the beam paths of the individual moderators are combined in a concerted manner so as to create a superimposed neutron beam with an effective mean beam direction. The superimposed neutron beam has a multi spectrum composed of the single spectrums of several moderators, whereby a larger spectral width is obtained, making various applications in different neutron energy fields possible. The multi spectrum can be further improved in terms of the intensity thereof and the beam quality by adding further neutron-optical components, particularly in the form of an energy-depending switching super reflector, and by switching between moderators.
