20100232740 | POF STRAIN SENSOR USING PHASE MEASUREMENT TECHNIQUES - An optical fiber sensor has a measurement path and a reference path. Both paths each consist of two optical fibers and are fed with modulated light. The fibers of the reference path have a predefined difference in length, whereas the fibers of the measurement path are the same length. All fibers are at approximately the same temperature. An evaluation circuit determines the phase differences in each case between the fibers of the measurement path and of the reference path. A measurement value calculated from the phase differences is then output. | 09-16-2010 |
20100252026 | Tracking Unit For A Solar Collector - A tracking unit for solar collectors has at least two panels, which can each be pivoted about a longitudinal axis. The axes are arranged on a rotable frame on one plane. The position of each axis within the individual panels is offset by a offset Δx in relation to the adjacent panels. The individual panels are moved by means of a lifting mechanism that pivots each of the panels about the same angle. This arrangement significantly reduces mutual shading and increases efficiency by about 10%. | 10-07-2010 |
20110199782 | LUMINOUS PENCIL - A pencil has a pencil casing made of a sharpenable casing material and a core held in a central receiving bore in the casing material that extends in the longitudinal direction of the pencil. One or more optical fibers made of a sharpenable material is/are arranged in the pencil casing. The optical fiber or optical fibers extends in the longitudinal direction as well and are at least partially surrounded by the material of the pencil casing. A light entry surface of the at least one optical fiber is arranged at the rear end of the pencil casing such that a light source, which is present there, can be used to inject light to said light entry surface. The light exit surface of the optical fiber exits at the forward end of the pencil casing. | 08-18-2011 |
20130243375 | OPTICAL ROTARY TRANSMITTER - An optical rotary transmitter which ensures the reliable transmission of optical signals in conjunction with a comparatively simple construction comprises two parts spaced apart from one another which are rotatable relative to one another about a common centre axis and the first of which comprises a first circular light coupler ( | 09-19-2013 |

20150153168 | Device for determining the position of a signal source - The invention relates to a device for determining the position of a signal source configured to emit signals modulated by a modulation frequency, comprising: a conductor arranged in such a way that it receives the modulated signals at various positions along the conductor and configured to conduct the modulated signal, respectively in opposite directions, to a first conductor end and to a second conductor end when a modulated signal is received; a detector configured to acquire the modulated signal at the first conductor end and at the second conductor end; and a determination apparatus configured to: determine a phase difference between the modulated signal acquired at the first conductor end and the modulated signal acquired at the second conductor end, and determine the position of the signal source in relation to the conductor on the basis of the phase difference. | 06-04-2015 |

20100184398 | METHOD AND SYSTEM FOR NOISE SUPPRESSION IN ANTENNA - A system includes an antenna to receive a communications signal, an amplifier coupled to the antenna to amplify the communications signal, and a processor coupled to the amplifier to process the communications signal using high-order statistics to suppress noise in the communications signal. The processor may use a bispectrum function to remove at least a portion of the noise, and at least one of the phase of the bispectrum and the amplitude of the bispectrum to reconstruct the communications signal. | 07-22-2010 |
20110019611 | SYSTEMS AND METHODS FOR DETECTING SPREAD SPECTRUM SIGNALS IN AN AREA OF INTEREST - Systems and methods are provided for detecting and geo-locating a target transmitting a CDMA or other spread-spectrum signal within an area of interest. Targets are identified by spatially-dividing the area of interest into a number of cells. First and second receiving beams are sequentially directed toward each of the cells from two or more different intercept sites. The presence of the spread-spectrum signal within each cell is identified from the signals received at each directional beam, and if the spread-spectrum signal is present in both the first and the second receiving beams, then the target can be indicated to be present within the cell. | 01-27-2011 |
20110309982 | RECEIVING STATION AND METHODS FOR DETERMINING AN ANGLE-OF-ARRIVAL OF SHORT-DURATION SIGNALS USING SURFACE-ACOUSTIC-WAVE (SAW) DEVICES - Embodiments of a system and method for determining an angle-of-arrival (AOA) of signals received from a transmitting device are shown. Signals from the transmitting device are received through two or more pairs of spatially-diverse antennas. A non-inverted version of the signals received through a first antenna of a pair is injected into a first input of a surface-acoustic-wave (SAW) device. An inverted version of the signals received through a second antenna of the pair is injected into a second input of the SAW device. Signals present at tap outputs are processed to determine a time-difference-of-arrival (TDOA) between the signals received through each pair of antennas. The AOA may be calculated from the TDOAs determined from two or more pairs of antennas. | 12-22-2011 |
