  • Patent number: 10928514
    Abstract: Ultrasound method for extracting information from signal components relating to spatial locations in a target region such as for example image reconstruction in the spatial and temporal frequency domain comprises the steps of: Transmitting an unfocussed acoustic wave in a target region; extracting information of the scatterers in the target region from signal components relating to spatial locations of the target region by applying a backpropagation algorithm to the radiofrequency signals generated by transformation of the reflected acoustic waves and which radiofrequency signals has been transformed in the frequency-wavenumber domain and transformed back to the time spatial domain after backpropagation processing, the system provides the further step of optimizing the extracted information by applying corrections to the radio frequency received signals in the frequency-wavenumber domain. The invention relates also to an ultrasound system for carrying out said method.

  • Patent number: 10880016
    Abstract: In one example embodiment, a server obtains a labeled fingerprint of an ultrasound-capable client device. Based on the labeled fingerprint, the server determines that the ultrasound-capable client device is in physical proximity with a collaboration endpoint. The server subsequently obtains an unlabeled fingerprint of an ultrasound-incapable client device. Based on the unlabeled fingerprint and the labeled fingerprint, the server determines that the ultrasound-incapable client device is a meeting attendee device for a collaboration meeting to which the collaboration endpoint is connected. In response to determining that the ultrasound-incapable client device is the meeting attendee device for the collaboration meeting, the server connects the ultrasound-incapable client device to the collaboration endpoint.

  • Patent number: 10877138
    Abstract: In the method for transmitting data representing an ultrasonic measurement signal of an ultrasonic measuring device, in particular for a vehicle, from a transmitter to a receiver a digitized analog ultrasonic measurement signal is provided in the transmitter. On the transmitter side the ultrasonic measurement signal is sampled at a multiple of its frequency and divided into individual successive blocks of sampling values. The sampling values of the sampled ultrasonic measurement signal are transformed in blocks into the frequency range. Those frequency portions of the spectrum whose amplitude is smaller than a presettable threshold value, or the frequency portions of the spectrum above an upper frequency limit value and/or below a lower frequency limit value are removed. The amplitude range covered by the remaining frequency spectrum is scaled by a scaling factor for further reduction of the data. The data of each block with the scaling factor assigned to the respective block are transmitted to the receiver.
