Patent number: 8792566Abstract: An expansion of known serial data links, for example ETHERNET, published in IEEE802.3, for directly transmitting random events without having to carry out synchronization with a clock signal or having to wait for a cyclical transmission time. Two different, random events are represented using two differently coded individual pulses and are transmitted in an event-controlled manner. A jitter-free latency of 45 ns between the event and its reception is possible over a line length of 8 m, for example. The expansion is particularly suitable for the short, digital data links between a node and a plurality of modules, as are required in modern electrical discharge machines, machine tools and similar electronic systems.Type: GrantFiled: March 21, 2012Date of Patent: July 29, 2014Assignee: AGIE Charmilles SAInventors: Ernst Buehler, Reto Knaak, Rino D'Amario

Patent number: 7948758Abstract: The invention relates to a circuit board unit and a method for production thereof. The circuit board unit comprises a circuit board topmost laminate with conductive tracks on the upper side for mounting surface-mountable devices. The circuit board topmost laminate features a thickness dimensioned such that the anticipated heat dissipated by the surface-mountable devices is transported from the upper side to the underside of the circuit board laminate to good effect. The circuit board unit further comprises an electrically insulating laminate arranged under the circuit board topmost laminate, inserts made of a material with good heat conductivity and electrical insulation embedded in the electrically insulating laminate at sites below surface-mountable devices with high heat dissipation, and a cooling plate arranged below the electrically insulating laminate and the inserts.Type: GrantFiled: October 25, 2007Date of Patent: May 24, 2011Assignees: Agie Charmilles SA, Charmilles Technologies SAInventors: Ernst Bühler, Rino D'Amario, Reto Knaak

Patent number: 7816620Abstract: The invention relates to a method and generator for generating a time sequence of EDM pulses having a predefined ignition voltage for electrical discharge machining. An AC voltage is generated from a DC voltage, furnished by a bipolar current source. The AC voltage is applied to an isolating transformer disposed between the bipolar current source and the spark gap. A first pulse capacitor is charged by the bipolar current source to a voltage corresponding to the ignition voltage. The ignition voltage provided by the isolating transformer is switched with a selected polarity to the spark gap.Type: GrantFiled: July 31, 2006Date of Patent: October 19, 2010Assignees: Agie Charmilles SA, Charmilles Technologies SAInventors: Ernst Buhler, Franck Besson, Rino D'Amario, Nicola Giandomenico, Reto Knaak
