  • Patent number: 10771167
    Abstract: Methods and system are provided to mitigate RF interferences during operation of an electrosurgical system. An electrosurgical system configured to output therapeutic RF energy may refrain from outputting RF energy in order to measure an RF interference for a group of candidate frequencies, and to select a frequency from the group of candidate frequencies for which the measured RF interference is below a threshold value, and to produce a feedback signal (a control signal) at the selected frequency to control operation of the electrosurgical system. During operation of the electrosurgical system the feedback signal may be filtered by a BPF whose fundamental frequency is set to the selected frequency, to thus obtain an interference free feedback signal and, consequently, a reliable control of the electrosurgical system.

  • Patent number: 10666691
    Abstract: A request to establish a communication session between the first communication endpoint and a second communication endpoint is received. For example, the request may be a Session Initiation Protocol (SIP) INVITE message to establish a voice communication session. A security classification for the communication session is determined. For example, the determined security classification may be that the call is top secret or unclassified. The security classification is not based on whether the communication session is solely encrypted. The security classification is inserted into the request to establish the communication session. The request to establish the communication session with the security classification is sent to the second communication endpoint. This allows the second endpoint to display the security classification. A similar process is used in a response to the request to establish the communication session to convey the security classification to the first communication endpoint.

  • Patent number: 10545210
    Abstract: Systems and methods for designing RF pulses using a technique that directly controls temperature rise via a compression model that is based on virtual observation points (“VOPs”) are provided. Thermal pre-simulations are first carried out for a given RF exposure time, coil, and subject model in order to obtain complex temperature matrices, after which the compression scheme follows. As one example, the thermal model employed can be Pennes' bio-heat equation. Focusing design constraints on the temperature rise instead of the absolute temperature allows for uncertain parameters to be dropped from the thermal model, making it more robust and less prone to errors. In some embodiments, the algorithm used for RF pulse design is the active-set (“A-S”) method.

    Abstract: A non-transitory computer-readable storage medium is presented including a power supply module configured to output power, a first energy module configured to receive the power and convert the power into a first waveform having a first phase, and to deliver the power in a first energy mode, and a second energy module configured to receive the power and convert the power into a second waveform having a second phase, and to deliver the power in a second energy mode. A host controller module is configured to control a type and a number of energy modalities provided by the generator platform and a comparator compares the first phase of the first waveform with the second phase of the second waveform in one or more of a plurality of sub-periods. An adjustment module adjusts a relative phase between the first and second waveforms based on results obtained from the comparator.

  • Patent number: 9937357
    Abstract: The present invention relates to a radiofrequency (RF) hyperthermia device for personalized treatment and diagnosis using capacitive coupling and without dipole antenna comprising a radiofrequency source, an amplifier, a sensor and a modulation signal input/generator, wherein the radiofrequency source produces a source signal which is modulated by the modulation signal input/generator using the phase information generated by homeostasis of the target to generate a modulated source signal, the modulated source signal is amplified by the amplifier and directed to a target, and the sensor detects the phase information generated by homeostasis of the target to provide a feedback signal, wherein the feedback signal modulates the source signal to generate a personalized modulated signal. This radiofrequency (RF) hyperthermia device is designed for personalized treatment and diagnosis of a target such as a patient or a malignant or tumorous area within a patient.
