Patent number: 9760822Abstract: An actively transmitting tag detects a shift of a phase of an antenna signal (as) with regard to a phase of a transmitted signal (ts) in time intervals with a length of one half-period of a subcarrier, in which time intervals it transmits high-frequency wave packets with their phase being inverted according to a communication protocol at the ends of said half-periods. Generation of said wave packets is controlled by said phase shift in a way that said phase shift retains its absolute value at transitions into subsequent half-periods. Synchronizing the tag's transmission to a received interrogator signal carried out even during tag's transmitting enables the tag to transmit according to protocol ISO 14443 B by inverting a phase at transitions between said half-periods. Said synchronizing is carried out although no time window without a tag transmitting exists within the transmitted data frame.Type: GrantFiled: January 14, 2014Date of Patent: September 12, 2017Assignee: STMicroelectronics International N.V.Inventors: Vinko Kunc, Maksimiljan Stiglic, Kosta Kovacic, Albin Pevec, Anton Stern

Patent number: 8867989Abstract: A calibrating output signal of the transmitter is generated in an interrogator in that a first output signal of a local oscillator is shallowly amplitude-modulated with a pilot signal having a frequency at which a contactless-card encodes data. A receiver reference signal is generated by combining the calibrating output signal of the transmitter and a signal whose carrier signal has a frequency equaling the frequency of the local oscillator signals, conducting the combined signal through a band-pass filter and amplifying it. A first and a second receiver output signals are cleared by subtracting the receiver reference signal, which has been attenuated by a calibrated factor and has a calibrated polarity, from the first and the second receiver output signal, respectively.Type: GrantFiled: April 15, 2008Date of Patent: October 21, 2014Assignee: AMS International AGInventors: Vinko Kunc, Andrej Vodopivec, Maja Atanasijevic-Kunc, Anton Stern

Patent number: 8315585Abstract: A difference between an output current signal (mos) of the mixing circuit (MC) and a current from a controlled current source (CCS) is conducted to an input of an operational amplifier (A). A control voltage (cv) for said current source is a voltage at the output of the operational amplifier (A) being filtered by a low-pass filter, whose limiting frequency equals a low frequency limit of the modulation signal in the received signal (rs). The method is speeded up in that the limiting frequency of the low-pass filter is increased by two to three orders of magnitude at the beginning and is gradually lowered to said value. A rather short time duration of the transient process is achieved so that the working point with a low voltage of the DC component and low-frequency components is set at least five times faster than so far.Type: GrantFiled: February 13, 2009Date of Patent: November 20, 2012Inventors: Vinko Kunc, Anton Stern, Andrej Vodopivec, Maja Atanasijevic-Kunc

Publication number: 20080119093Abstract: The invention relates to a press-fit pin (1) made from wire material for electrical contacts, in particular plug-in connectors. When using press-fit pins (1) made from wire material the problem of the tips (23) of the press-fit pins (1) being damaged by the press-fit tool has previously occurred. To be able to support a tool on press-fit pins (1) made from wire material without the tips (23) being damaged the press-fit pin (1) made from wire material is provided according to the invention with a shoulder element (3).Type: ApplicationFiled: November 20, 2007Publication date: May 22, 2008Inventors: Martin Bleicher, Christoph Goeppel, Peter Goesele, Erich Koehnert, Karl Lechner, Anton Stern, Kurt Vaas

Patent number: 7324040Abstract: An attack is activated in a receiver amplifier of an interrogator whenever an amplified input signal exceeds an attack threshold voltage value Vatt, and the receiver amplifier at least during a waiting period, the length of which preferrably equals the double length of the longest time interval between adjacent pulses in a transponder data wave packet, after the end of the attack does not respond in the sense of setting the gain. However, the amplifier responds with a decay activated after the lapse of the waiting period, which started when the instantaneous amplified signal value for the last time after the end of the attack exceeded a waiting threshold voltage level Vw. The decay rate is of the same order of magnitude as the attack rate. The improved method for automatically setting the gain renders it possible that the interrogator receiver within the non-contacting identification system practically does not change the essential characteristics of the input signal.Type: GrantFiled: December 22, 2003Date of Patent: January 29, 2008Inventors: Vinko Kunc, Anton Stern
