Publication number: 20230291134Abstract: Methods of delivering electric power to equipment of a communications access network are provided herein. In particular, a method of delivering electric power to the equipment includes generating an AC power signal having a frequency between 10 kHz and 500 kHz that is transmitted via a coaxial cable that is coupled between the equipment and a power monitor. The method includes identifying, using the power monitor, a reflection of the AC power signal via the coaxial cable to the power monitor. Moreover, the method includes adjusting a voltage of the AC power signal in response to identifying the reflection. Related systems and coaxial cables are also provided.Type: ApplicationFiled: July 23, 2021Publication date: September 14, 2023Applicant: ARRIS Enterprises LLCInventors: Zoran MARICEVIC, Marcel SCHEMMANN, John O.

Publication number: 20220065823Abstract: A measurement method is provided on an electrically conducting object. A first ultrasound wave is generated in the object by means of a first EMAT transmit transducer of a measurement arrangement. A first EMAT receive transducer of the measurement arrangement detects a first receive signal. The first receive signal comprises a first ultrasound signal resulting at least partially from the first ultrasound wave which has propagated through at least a part of the object, as well as a first electromagnetic interference signal. A second receive signal is also detected comprising a second electromagnetic interference signal by means of a first receive means of the measurement arrangement. The first receive signal and the second receive signal are processed jointly. At least the first receive signal is at least partially interference-suppressed.Type: ApplicationFiled: September 3, 2021Publication date: March 3, 2022Inventors: Eduard Blumenstein, Marcel Schemmann

Patent number: 9363027Abstract: Methods, systems, and computer readable media can be operable to facilitate the remote modulation of pre-transformed data. In embodiments, a CMTS can provide pre-transformed data in the frequency domain to a transmitter or receiver. Multiple network components can be bypassed when pre-transformed data is delivered directly to a transmitter or receiver, thus improving the amount of network capacity and available network resources. In embodiments, pre-transformed data can be transformed and modulated at a receiver.Type: GrantFiled: August 18, 2014Date of Patent: June 7, 2016Assignee: ARRIS Enterprises, Inc.Inventors: Marcel Schemmann, Zoran Maricevic

Patent number: 9229024Abstract: The method is based on a determination of the orientation of the sensor to the surface moving with respect to the sensor and then acquiring data where the lateral velocity is small and the forward velocity is large. Then, the orientation of the sensor with respect to the direction of the forward velocity is determined and the velocity data subsequently measured are corrected using the measured orientation of the sensor with respect to the reference surface and the forward velocity direction.Type: GrantFiled: January 18, 2010Date of Patent: January 5, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Mark Carpaij, Alexander Marc Van Der Lee, Bernd Engelbrecht, Marcel Schemmann, Carsten Heinks, Holger Moench

Patent number: 8982334Abstract: The present invention refers to a method of operating a self-mixing interference sensor and a corresponding self-mixing interference sensor device. In the method the laser (1) of the device is controlled to periodically emit a laser pulse followed by an emission period of laser radiation having a lower amplitude. The pulse width of the laser pulse is selected such that the pulse after reflection at the object (3) re-enters the laser (1) during the emission period of laser radiation with lower amplitude. The corresponding SMI signal has an increased signal to noise ratio.Type: GrantFiled: August 10, 2010Date of Patent: March 17, 2015Assignee: Koninklijke Philips N.V.Inventors: Alexander Marc Van Der Lee, Mark Carpaij, Holger Moench, Marcel Schemmann

Patent number: 7994468Abstract: An optical input device for measuring relative movement between an object (15) and a sensor unit comprising a laser device (3, 5) having a laser cavity for emitting a measuring beam (13, 17) and a respective radiation-sensitive detector (4, 6) for generating a measurement signal representative of changes in the operation of the laser device (3, 5) as a result of measuring beam radiation re-entering the laser cavity. A sensor unit is provided for measuring relative movement along each measuring axis in an action plane, and the resultant measurement signal from one or each of the sensor units is used to determine distance and/or movement of the input device and the object (15) relative to each other along a measuring axis transverse to the action plane by summing the offset frequency of a rising and falling slope of the measurement signal.Type: GrantFiled: August 23, 2006Date of Patent: August 9, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Rene Duijve, Aalbert Stek, Carsten Heinks, Marcel Schemmann

Patent number: 7920249Abstract: A device for measuring movement of an object (15) and the device relative to each other. The device comprises a laser (3) for generating a measuring beam (13), which is converged by a lens (10) in an action plane. Radiation reflected by the object (15) is converged to re-enter the laser cavity to generate a self-mixing effect in the laser (3). Measuring means (4) are provided to receive the reflected measuring beam radiation and enable the frequency difference between the measuring beam (13) and the reflected measuring beam radiation to be determined, which is representative of the relative movement.Type: GrantFiled: December 20, 2006Date of Patent: April 5, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Carsten Heinks, Marcel Schemmann

Patent number: 7889353Abstract: A method and optical module for measuring relative movement of an input device and object (15) along at least one measuring axis. A laser device (3) having a laser cavity is provided for generating a measuring beam (13) in respect of each measuring axis. The measuring beam (13) is used to illuminate the object (15) and measuring beam radiation reflected from the object (15) and re-entering the laser cavity generates a self-mixing effect in the laser and causes changes in operation of the laser cavity. A detector (4) is used to generate a measurement signal representative of these changes and an electronic processing circuit (18) selects, in dependence on the speed of relative movement, one of at least two parameters of the measurement signal for use in determining the speed and direction of relative movement.Type: GrantFiled: August 24, 2006Date of Patent: February 15, 2011Assignee: Koninklijke Philips Electronics N.V.Inventors: Marcel Schemmann, Carsten Heinks, Paraskevas Dunias, Aalbert Stek
