Title: Radiation Source
Inventor: JOHANNES ANTONIUS GERARDUS AKKERMANS
IPC: G03F7/20
Filed: 2017-11-23
Abstract: An electron bunch modulator comprises: an energy modulator; a first dispersive electron optics; a chirp module; and a second dispersive electron optics. The energy modulator is for receiving a bunched electron beam and is operable to produce an energy modulation within each bunch of the bunched electron beam at a first distance scale λ1. The first dispersive electron optics is arranged to receive the bunched electron 5 beam output by the energy modulator, disperse the electron bunches and subsequently recombine them such that the distance travelled by an electron within a given electron bunch is dependent on its energy. The chirp module is operable to receive the bunched electron beam output by the first dispersive electron optics and to produce a longitudinal phase space correlation in each electron bunch. The second dispersive electron optics is arranged to receive the bunched electron beam output by the chirp module, disperse the 10 electron bunches and subsequently recombine them such that the distance travelled by an electron within a given electron bunch is dependent on its energy in an opposite sense to the first dispersive electron optics.

Title: Railles transporter device for trucks over floor area - electronically control led with code-readers at changing-points and track interruption as part of code
IPC: G05D1/02
Filed: 1974-06-26
Abstract: To make leadtrack and code readers less complicated, the leadtrack itself is used as part of the code. Just before any interchange the leadtrack is interrupted and this interruption is part of the direction code which makes additional deflection codes unnecessary. The transporter has a length measurement element ot measure the interruption and compares it with given data to determine whether the correct interchange has been reached. Therefore the electronic code reader to receive the diversion signal can now be less sensitive and therefore less prone to interference.

Title: Method for discriminating between the high and low impedance state of a switching element
IPC: H01H9/16
Filed: 1992-06-24
Abstract: The device according to the invention comprises a transformer, whose first winding is connected in parallel with the switching element to be measured. Connected in series with a second winding of the transformer is a resistor. Upstream of the resistor, first means are connected for supplying an electrical pulse to the second winding of the transformer by means of the resistor. Connected downstream of the resistor are second means for detecting the response to the electrical pulse supplied. The second means can be provided with a pulse detection element. If a pulse is measured by the pulse detection element while the pulse is applied, the switching element is in the high impedance state. Preferably, the second means comprise a comparison element, and a capacitor is connected in parallel with the first winding of the transformer. If the comparison element, after termination of the pulse applied, detects a damped LC oscillation, the switching element is in the high impedance state. To further damp the damped LC oscillation, provision can be made for a resistor connected in parallel to the first winding of the transformer and the capacitor. Also, the comparison element preferably compares the first wave prior to a first zero crossing of the damped LC oscillation with a reference voltage.
