Patent number: 9359790Abstract: An electronic key, e.g., a wireless key for a vehicle, is disclosed. The key has a housing with a housing wall having a semi-transparent display section. An information symbol for representing information to be displayed to a user is further provided. The display section has a housing wall section with reduced wall thickness, wherein a light-impermeable layer, in which recesses representing the information symbol are produced, is applied to an inner side of the housing. The combination of a housing wall section of reduced thickness and the light-impermeable layer on the inner side of the housing as an information symbol provided in the display section creates an information symbol that may be very sharp and bright when backlit and, due to the semitransparent formation of the display section, is not visible when not backlit.Type: GrantFiled: June 19, 2013Date of Patent: June 7, 2016Assignee: CONTINENTAL AUTOMOTIVE GMBHInventors: Ulrich Stetter, Rolf Friedrich

Patent number: 8022338Abstract: The invention relates to a heating element for a filter press, that can be supplied with a fluid heating medium and comprises at least one heating plate consisting of a heat-conducting material and extending essentially over a plane. Said heating plate is fixed to a base body of the heating element, exclusively in a continuous partial region, the surface of the continuous partial region being smaller than the remaining surface of the heating plate. The invention also relates to a heating element for a filter press, comprising two heating plates which are interconnected by means of spacers, outside the lateral expansion of the base body. The entire base body can be freely displaced between the heating plates, in relation thereto, at least in such a way that a thermal expansion of the heating plates and a different thermal expansion of the base body can take place.Type: GrantFiled: August 3, 2004Date of Patent: September 20, 2011Assignee: Klinkau GmbH & Co.Inventors: Lothar Kuffel, Johann Zeller, Rolf Friedrich Buhl

Patent number: 7382843Abstract: 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.Type: GrantFiled: December 9, 2002Date of Patent: June 3, 2008Assignee: NXP B.V.Inventors: Stephan Koch, Gerd Jakob Ernst Scheller, Rolf Friedrich Philipp Becker

Patent number: 7342435Abstract: Apparatus (10) comprising a level shifter (15) connectable to a signal input (1) for receiving an input signal (s(t)) with a negative signal swing. The level shifter (15) provides for a DC shift of the input signal (s(t)) to provide an output signal (r(t)) with positive signal swing. The level shifter (15) comprises an amplifier (17) with a first input (11), a second input (12), and an output (13). A first capacitor (C1), a second capacitor (C2), a reference voltage supply (16), and a transistor (14; 74) serving as a switch, are arranged in a network as follows: the first capacitor (C1) is arranged between the signal input (1) and the first input (11), the second capacitor (C2) is arranged in a feedback-loop (18) between the output (13) and the first input (11), and the reference voltage supply (16) is connected to the second input (12). The transistor (14) is arranged in a branch (19) that bridges the second capacitor (C2), whereby a control signal (CNTRL) is applicable to a gate (14.Type: GrantFiled: July 8, 2004Date of Patent: March 11, 2008Assignee: NXP B.V.Inventors: Rolf Friedrich Philipp Becker, Willem Hendrik Groeneweg, Wolfgang Kemper

Patent number: 6538474Abstract: The invention proposes an interface circuit having a very low power consumption and generating very low interference noise in the sensitive band of ratio chips. It is advantageously used to interface a microprocessor with a baseband radio processor in a telecommunication device, for example in DECT or GSM phones. The interface of the invention is current-driven. It comprises a current driver for transmitting a current in a transmission line depending on the data to be transferred. It also comprises a current receiver. The current receiver has an input node and an output node interconnected via a current mirror circuit, so that the voltage on said input node is near to the ground voltage and the voltage on said output node is changing depending on the transferred data.Type: GrantFiled: July 17, 2001Date of Patent: March 25, 2003Assignee: Koninklijke Philips Electronics N.V.Inventors: Thomas Wolff, Rolf Friedrich Philipp Becker

Patent number: 6448751Abstract: This invention concerns a power supply voltage generator (1) for providing a second supply voltage (VDD2) for an electronic circuitry (60). A voltage converter (50) receives a first supply voltage (VDD1), and converts this into said second supply voltage (VDD2), such that its output voltage (VDD2) fluctuates in a control range between a lower limit (VLOW) and an upper limit (VHIGH). A voltage parameter source circuitry (3) generates a voltage parameter signal (VLOW) which is substantially equal to the minimum supply voltage value (Vmin) of the electronic circuitry (60), and feeds this voltage parameter signal (VLOW) to a parameter input (53) of the converter (50). The voltage parameter source circuitry (3) comprises a VCO (10) incorporated in a PLL. The voltage parameter signal (VLOW) is derived from a control signal (Vcontr) for the VCO (10).Type: GrantFiled: October 27, 2000Date of Patent: September 10, 2002Assignee: Koninklijke Philips Electronics N.V.Inventor: Rolf Friedrich Philipp Becker
