  • Patent number: 11831404
    Abstract: A method for synchronizing at least two environment sensors of a multi-sensor system using a central processing unit. In the method, the environment sensors acquire sensor signals that represent at least one item of environment information. The respective environment sensors generate data packets which include the respective acquired sensor signals and/or measured variables derived from the sensor signals in each case. These data packets are received by the central processing unit via a data network. Signal propagation times of the data packets for each environment sensor are ascertained using an algorithm, and a mean signal propagation time of data packets from a respective environment sensor is determined based on a content comparison of the measured variables included by the data packets with corresponding measured variables from data packets of at least one other environment sensor, and the determined mean signal propagation time is assigned to the respective environment sensor.

  • Patent number: 11108429
    Abstract: Covert acoustic communications (CAC) through solid propagation channels that connect node pairs is achieved by encoding signals using spread spectrum coding techniques that position the encoded signal at a center frequency fc within a narrow frequency bandwidth BWNB in which the amplitude of the channel response H(f) between each node pair is relatively high. The channel response H(f), bandwidth BWNB and center frequency fc, and accordingly the signal data rate will adapt for each node pair and possibly each side of the node pair. A pre-distortion filter 1/H(f) pre-distorts the encoded signal over bandwidth BWNB to compensate for material and modal dispersion and multipath between the node pair. This technique avoids the problems associated with frequency dependent attenuation of the continuous solid path and allows for simultaneous transmission and reception of signals among the multiple node pairs.

  • Patent number: 11012989
    Abstract: The present invention relates to underwater communication and, more particularly to a signal transmission method and device which configure and transmit physical channel information such that low-power control is performed in underwater communication. The present invention configures the physical channel information such that a reception node side can check through a combination of preambles whether a signal is provided to itself, when forward direction communication is performed in a centralized underwater communication network. Therefore, the present invention performs the control such that only a relevant reception node requiring data reception performs a demodulation operation, without requiring all reception nodes to always perform demodulation in a forward direction communication process. Through this process, many reception nodes do not perform unnecessary demodulation operations in the forward direction communication process, thereby providing an effect of preventing unnecessary power consumption.

    Abstract: Methods and systems for minimizing RMS travel time error in a seismic data acquisition. Field measurements of source and receiver coordinates, speed of sound in water as a function of depth and time, receiver timing, and clock drift are first collected. The seismic data is then examined to measure travel time from each source to each receiver. A model travel time is computed based on the field measurements. By iteratively perturbing at least one of the field measured data using a look-up table and calculating the travel time after each perturbation until an acceptable RMS error has been achieved, conditioned seismic data that takes into account the dynamic nature of the water column will provide the basis for creating an accurate seismic map that is unaffected by the changing water conditions.

  • Patent number: 10594409
    Abstract: Ultrasonic through metal communication systems are an effective solution for transmitting data across a metal barrier when the structural integrity of the barrier cannot be compromised by physically penetrating it. Substantial improvements in through metal communication systems have been made in recent years, enabling high speed communications of up to 15 Mbps, as well as power transmission up to 30 W across flat walls. A system is described that allows for ultrasonic through metal communication across the wall of a steel tube. Primary challenges of 1) transducer contact, 2) curvature effect on echoes, and 3) alignment are analyzed and addressed through the use of radial mode piezoelectric transducers, transducer “horns”, and Electromagnetic Acoustic Transducers (EMATs). The resulting system shows no significant loss due to changes in alignment, allows for the use of either piezoelectric transducers or EMATs externally, and achieves max data rates of approximately 600 kbps without echo equalization.

  • Patent number: 10488246
    Abstract: An escape system for a sinking car and an ultrasonic component thereof are illustrated. In the present disclosure, an ultrasonic signal transmitting unit capable of emitting ultrasonic is installed on the car. When the car falls into the water, based upon an acoustic resistance concept which the ultrasonic propagated in air collides and transmits into the water, a difference between a reflection or transmittance rate of the ultrasonic and a corresponding set value can be calculated, or alternatively, a difference between a reflection time deviation or a reflection distance of the ultrasonic and a corresponding set value can be calculated. Therefore, a warning signal indicating that the car falls into the water can be fast sent, and this makes sure that the rescue opportunity which the car falls into the water can be grasped to decrease the damage or death of the user.

  • Patent number: 10205561
    Abstract: A method for an electronic receiver of processing a packet of a hybrid automatic repeat request (HARQ) system is disclosed. The method comprises receiving a first transmission of the packet, wherein the first transmission comprises a first plurality of soft symbol values and determining whether the first plurality of soft symbol values meets a stop criterion. If it is determined that the first plurality of soft symbol values does not meet the stop criterion, a subject of the first plurality of soft symbol values is determined, wherein the subset comprises a number of soft symbol values of the first plurality of soft symbol values, the number being greater than zero and less than the first plurality. The subset of the first plurality of soft symbol values is stored in a HARQ buffer.

  • Patent number: 10135661
    Abstract: Phase noise estimation and cancellation as disclosed herein may allow cost-efficient increase of capacity in communications by enabling very high QAM levels. The proposed solution is potentially applicable to any single carrier applications where phase noise is a limiting factor and a required order of modulation is very high. For example, disclosed embodiments may enable high QAM levels for microwave backhauls despite severe phase noise sensitivity. One embodiment involves a pilot-aided and BCJR-based sequential search algorithm that accurately estimates and subtracts fast-varying phase noise symbol-by-symbol. Residual BER performance is evaluated under the most challenging phase noise scenarios. FPGA emulation results show detection and removal of a significant amount of phase noise and zero BER performance even for complex 1K-QAM and above.

    Abstract: A sample rate converter for an oversampled data stream develops interpolated samples at a first oversample rate, from samples at a second oversample rate; wherein the first oversample rate is a non-integer multiple of the second oversample rate. When the samples at the second oversample rate are changing state, at least two interpolated samples are generated or the interpolation is at least second order. When the sample at the second oversample rate is not changing state, the sample at the second oversample rate is passed substantially unchanged. In one embodiment of the invention, asynchronous sample rate conversion is performed, and the first oversample rate is a varying non-integer multiple of the second oversample rate.
