Publication number: 20220252697Abstract: A stationary radar device, which apart from a plurality of stationary receiving antennae, includes a plurality of stationary transmitting antennae for emitting primary radio waves. A frequency-modulated emitting signal is generated in two sequences. During the first sequences a plurality of successive first chirps are emitted by one of the transmitting antennae. A Doppler shift or a speed is computed from the temporal development of the respective first receiving signals. The second sequences are intermitted with the first sequences and each include one or more second chirps, wherein the second chirps are produced from different transmitting antennae. The second receiving signals which are effected by the second chirps are evaluated, in order by way of correlation of receiving signals that originate from second chips, which come from different transmitting antennae, to obtain a phase picture that is resolved in the azimuth.Type: ApplicationFiled: July 16, 2020Publication date: August 11, 2022Inventors: Patrick Rennhard, Simon Vogel, Roland Küng, Lorenz Meier

Patent number: 10397057Abstract: The present disclosure relates to communication networks. Some embodiments may include a communication network with two or more network nodes each comprising: a receiver discerning the signal quality of received signals; a transmitter sending signals at different data rates; and a controllable terminating impedance. A network node transmits the discerned signal quality to one or more additional network nodes, a network node records the signal qualities and corresponding values of the terminating impedances of the respective network nodes. A network node prescribes for additional network nodes a new respective value to set as a terminating impedance. A network node determines new terminating impedance values to optimize the data rate between the various network nodes and the signal quality at each of the network nodes.Type: GrantFiled: October 22, 2015Date of Patent: August 27, 2019Assignee: SIEMENS SCHWEIZ AGInventors: Bernhard Blattmann, Oskar Camenzind, Juerg Eggerschwiler, Roland Kueng

Patent number: 9767327Abstract: An RFID network, comprising a plurality of RFID read/write devices, which are connected to a central controller via a communication network, has problems as the network size increases. The mutual interference potential on the air interfaces increases, high demands are placed on the communication network with respect to availability, and the efficiency of the controller per RFID write/read device decreases. If part of the resources and the intelligence of the controller are distributed to, or forwarded to, an RFID system unit comprising the RFID read/write device, some of the load is removed from the controller. The RFID system units are notified of the operating sequences to be performed via a mission and said sequences are performed largely synchronously so that the interference potential decreases. Due to the distributed intelligence, the demand with respect to the availability of the communication network likewise decreases and the central controller can provide more resources for processing applications.Type: GrantFiled: December 11, 2007Date of Patent: September 19, 2017Assignee: INTERMEC IP CORP.Inventor: Roland Küng

Patent number: 6630900Abstract: The invention relates to a system suitable for a remote interrogation of passive transponders using chirp signals for interrogation. The transponder preferably has an encoding unit (11), a calibrating unit (12) and a measuring unit (13) each with a plurality of parallel channels (11.1 to 11.5, 12.1 and 13.1 to 13.2). The encoding unit and the calibrating unit are preferably jointly incorporated with a common delay line (14) on the same SAW chip. The interrogation signals received in the transponder via an antenna (10) are delayed characteristically and code-specifically, in particular in the encoding and calibrating unit. Decoding in the interrogation station is preformed by discrete Fourier transformation of the response signal and subsequent evaluation of the spectrum. To correct general disturbing influences on the delay of the response signal, said signal is calibrated using a single calibrating component in the response signal.Type: GrantFiled: May 3, 2002Date of Patent: October 7, 2003Assignee: Hera Rotterdam B.V.Inventors: Roland Stierlin, Roland Küng

Patent number: 4984247Abstract: A base station (BS) and mobile user stations (MS) each with a transmitter (S), a receiver (E) for multipath reception and a control unit (ST) are provided in each cell. Exactly one set of several sequence sets of the auxiliary function used for spectrum spreading is allocated to each cell. Sequences of several sets in pairs have the property that the absolute values of the normalized periodic cross-correlation functions are much smaller than one and for sequences within a set the cross-correlation function in pairs is optimally small around the zero point. Data synchronous generation of the transmission signals takes place in the base station (BS) for all simultaneous connections and the data clock of the received signal is used as data clock of the transmission signal of the user station (MS).Application for digital data transmission in buildings and local areas for the configuration of a so called cordless LAN are considered.Type: GrantFiled: September 29, 1989Date of Patent: January 8, 1991Assignee: Ascom Zelcom AGInventors: Hans Kaufmann, Roland Kueng, Urs Grob, Arnold Welti
