Patent number: 8165740Abstract: A device and a method for bidirectional single-wire data transmission of data information between an electronic control unit and at least one peripheral unit. A predefined constant voltage and/or a predefined constant current is applied to a driver device of the electronic control unit to produce voltage-coded and/or current-coded information. The voltage-coded and/or current-coded information is transmitted from the driver device of the electronic control unit to a driver device 30 of the peripheral unit via a single-wire line. At least the driver logic of the driver device and/or the communication logic of the peripheral unit are triggered and powered through the current flow. Information occurring on the peripheral unit is current-coded and/or voltage coded due to the triggering thereof.Type: GrantFiled: July 1, 2004Date of Patent: April 24, 2012Inventors: Rolf Kraemer, Ulrich Bentel, Bernhard Eisele, Markus Ketterer, Uwe Schiller, Juergen Stein

Patent number: 7392128Abstract: A device and a method are described for bidirectional single-wire data transmission of information between a control unit and at least one peripheral unit, having the following steps: generating a first current flow from the control unit to the peripheral unit during first time slots via a single-wire line to transmit voltage-coded or current-coded information from the control unit to the peripheral unit; and/or generating a second current flow from the peripheral unit to the control unit during second time slots via the single-wire line to upload voltage-coded or current-coded information from the peripheral unit to the control unit; the first and second time slots being implemented so they do not mutually overlap; and/or generating, in the first and/or second time slots, additional information to be transmitted and/or uploaded, which is transmitted as digital or analog signals by modulating the current or the voltage of the single-wire line and is analyzed in the control unit or the peripheral unit.Type: GrantFiled: July 2, 2004Date of Patent: June 24, 2008Assignee: Robert Bosch GmbHInventors: Rolf Kraemer, Ulrich Bentel, Bernhard Eisele, Markus Ketterer, Uwe Schiller, Juergen Stein

Publication number: 20060222469Abstract: The present invention provides a new drilling tool useful in machining hydraulic port seals for fluid power ports. The drilling tool drills the port hole to size in a solid material for the minor thread diameter in combination with forming the port in a single operation. The drilling tool has a tool holder having a rotational axis, a first drilling insert having cutting surfaces on a first side and a mounting surface on a second side, at least one second drilling insert having a predetermined cutting surface portion and a mounting portion which is mounted on the holder at a location from the rotational axis of the holder. The at least one second drilling insert has first and second portions which engage and machine a work piece in a drilling operation to form a spot face and a seal form.Type: ApplicationFiled: January 10, 2006Publication date: October 5, 2006Applicant: Allied Machine & Engineering Corp.Inventors: Joseph Nuzzi, Rolf Kraemer

Patent number: 6529511Abstract: A local area ring network operating in the asynchronous transfer mode (ATM) has a plurality of stations and network interfaces (transceivers), each network interface having a send and a receive ring connection. Setting up a call, exchange of information during the call and call clear-down are effected digitally via the exchange of ATM cells in whose header logic trunk identifiers (virtual path identifier VPI and virtual channel identifier VCI) are stored. At least one network interface includes a converter for at least partly and reversibly converting available data bytes in the header of the ATM cell into an identifier specific to the network. A header translation table in the converter is updated during the call set-up or call clear-down phase.Type: GrantFiled: April 16, 1998Date of Patent: March 4, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Yonggang Du, Andries Van Wageningen, Rolf Kraemer
