Real-Time Imaging System For Monitoring And Control Of Thermal Therapy Treatments

View page
US Patent:
20220409062, Dec 29, 2022
Filed:
Jul 15, 2022
Appl. No.:
17/865717
Inventors:
- Los Angeles CA, US
Mark S. Haynes - Pasadena CA, US
Mahta Moghaddam - Los Angeles CA, US
Guanbo Chen - Los Angeles CA, US
International Classification:
A61B 5/01
A61B 5/055
A61B 5/00
Abstract:
Methods and systems of monitoring and controlling thermal therapy treatments. One method includes determining, with an electronic processor, a propagation constant for a plurality of waveports. The method also includes modeling an object within an imaging cavity using a sparse mesh model. The method also includes determining a simulated impedance of the object based on the model of the object. The method also includes calibrating the simulated impedance with a theoretical impedance numerically calculated for the object. The method also includes determining a distribution of an electric field and a distribution of a magnetic field for a mode in a conformal modeled waveport based on the calibrated impedance and the model of the object. The method also includes exciting the plurality of waveports to generate the determined distribution of the electric field and the distribution of the magnetic field.

US Patent:
20220377664, Nov 24, 2022
Filed:
Mar 25, 2022
Appl. No.:
17/656589
Inventors:
- Suwon-si, KR
Wenxun Qiu - Allen TX, US
Guanbo Chen - McKinney TX, US
Peshal Nayak - Plano TX, US
International Classification:
H04W 52/02
G06V 10/764
G06K 9/62
Abstract:
A method includes obtaining network traffic information based on network traffic received during a time window. The method also includes determining a network service type using a machine learning classification system operating on the network traffic information. The method also includes determining a latency requirement based on the network service type. The method also includes adjusting one or more Target Wakeup Time (TWT) intervals and a wake duration based on the latency requirement to optimize power consumption of a Wi-Fi station.

US Patent:
20220201533, Jun 23, 2022
Filed:
Aug 12, 2021
Appl. No.:
17/444981
Inventors:
- Suwon-si, KR
Guanbo Chen - Allen TX, US
Wenxun Qiu - Allen TX, US
International Classification:
H04W 28/02
H04W 52/02
H04W 24/08
Abstract:
A wireless communication device comprising a processor configured to obtain first information on network conditions and second information on packets delivered to another communication device during a current target wake time (TWT) session, and to update a TWT service period (SP) duration for a future TWT session based on the first information and the second information.

Presence Detection And Recognition With Wi-Fi

US Patent:
20230109149, Apr 6, 2023
Filed:
Sep 29, 2022
Appl. No.:
17/936799
Inventors:
- Suwon-si, KR
Guanbo Chen - McKinney TX, US
Dong Li - Plano TX, US
Abhishek Sehgal - Plano TX, US
International Classification:
G01S 5/02
H04W 64/00
G01S 13/50
Abstract:
A method includes receiving CSI data for at least one communication link between a first electronic device (ED1) and a Wi-Fi device in a 3D space. The method includes preprocessing the CSI data; and determining whether a motion of an object is detected within a threshold distance to the ED1 based on the preprocessed CSI data. The detection of the motion of the object corresponds to a determination that the object is present in the space. The detection of no motion of the object corresponds to a determination that the object is not present in the space. The method includes outputting at least one of: a first indicator indicating that the space is empty, in response to the determination that the object is not present in the space; or a second indicator indicating that the space is occupied, in response to the determination that the object is present in the space.

System And Method For Real-Time Tracking Of A Probe During A Procedure

View page
US Patent:
20200196905, Jun 25, 2020
Filed:
Aug 21, 2018
Appl. No.:
16/641115
Inventors:
Guanbo CHEN - Coralville IA, US
Mahta MOGHADDAM - Los Angeles CA, US
Pratik SHAH - Vista CA, US
John STANG - Los Angeles CA, US
- Los Angeles CA, US
International Classification:
A61B 5/06
A61B 5/05
A61B 5/00
A61B 34/10
A61B 34/20
Abstract:
Systems and methods for tracking a probe during a procedure. In one embodiment, the method includes monitoring a position of the probe in an imaging region during the procedure using microwave inverse scattering and contrast source inversion. The method also includes solving for a contrast source in the imaging region using compressive sensing and group sparsity. The contrast source exists at a surface of the probe or within the probe. The method further includes imaging the contrast source and the probe by solving a linear inverse scattering problem with a group sparsity constraint. The method also includes determining a location of the probe in the imaging region during the procedure based on the imaging of the contrast source and the probe. The method further includes displaying an image of the location of the probe relative to an anatomy feature in the imaging region during the procedure.
