System and method for contactless Blood Pressure determination
Issued US US 10,376,192 B2
A system and method for contactless blood pressure determination . The method includes : receiving a captured image sequence ; determining , using a trained hemoglobin concentration ( HC ) changes machine learning model , bit values from a set of bitplanes in the captured image sequence that represent the HC changes of the subject ; determining a blood flow data signal ; extracting one or more domain knowledge signals associated with the determination of blood pressure ; building a trained…

domain knowledge signals ; determining , using the blood pressure machine learning model trained with a blood pressure training set , an estimation of blood pressure ; and outputting the determination of blood pressure.Other inventors -
System and method for camera-based heart rate tracking
Issued US US 10,117,588 B2
A system and method for camera - based heart rate tracking . The method includes : determining bit values from a set of bitplanes in a captured image sequence that represent the HC changes, determining a facial blood flow data signal for each of a plurality of predetermined regions of interest ( ROIs ) of the subject captured by the images based on the HC changes ; applying a band - pass filter of a passband approximating the heart rate to each of the blood flow data signals ; applying a…

Client/Bridge and Method and System for Using Same
Issued US US 9,077,558 B2
The transmission of data is accomplished across a network having wireless and wired interfaces. Data is transferred through a wireless interface from an Access Point to a Client/Bridge and then to one of a Intelligent Electrical Device (IED) connected to the Client/Bridge through a wired connection. Data is transferred from the Access Point to the Client/Bridge through a 4 address mode wireless interface having originator, transmitter, receiver and destination address fields. The Client/Bridge…
The transmission of data is accomplished across a network having wireless and wired interfaces. Data is transferred through a wireless interface from an Access Point to a Client/Bridge and then to one of a Intelligent Electrical Device (IED) connected to the Client/Bridge through a wired connection. Data is transferred from the Access Point to the Client/Bridge through a 4 address mode wireless interface having originator, transmitter, receiver and destination address fields. The Client/Bridge determines context cache information representing the media access control numbers of each of the IEDs connected to the Client/Bridge through the wired interface and transfers this context cache information to the AP. In the event of a failure of the Client/Bridge, the context cache information stored at the AP can be transferred to the Client/Bridge using the wireless interface to facilitate recovery of the Client/Bridge.

Open Frame Electronic Chassis For Enclosed Modules
Issued US US 7,974,093 B2
An open frame chassis has a top opening and a bottom opening permitting ambient airflow. A plurality of modules, each enclosing electrical components in thermal contact with a heat sink area of their corresponding module, can each be inserted in the chassis. Ambient air may flow from the bottom opening across the heat sink area of each module to the top opening to passively cool the modules and electrical components. Key pins guide the modules into place and prevent incorrect insertion of a…
An open frame chassis has a top opening and a bottom opening permitting ambient airflow. A plurality of modules, each enclosing electrical components in thermal contact with a heat sink area of their corresponding module, can each be inserted in the chassis. Ambient air may flow from the bottom opening across the heat sink area of each module to the top opening to passively cool the modules and electrical components. Key pins guide the modules into place and prevent incorrect insertion of a different type of electrical module not corresponding to the electrical connection of the chassis for that slot. Guide pins on corners of the modules mate with guide holes in the chassis to secure the module to the chassis and decrease vibration. Both sides of the chassis have side openings through which the fins of the modules in the end slots of the chassis may be exposed.
