Publication number: 20240095263Abstract: A map control module receives a stream of map data characterizing a geographic region proximal to a vehicle and outputs a moving map, and the moving map is divisible into a matrix of cells. A map item control receives a stream of point of interest (POI) data characterizing a plurality of POIs within the boundary and categorizes each of the plurality of POIs to define a set of categories. The map item control determines a display location of a map item within the matrix of cells for each of the plurality of POIs and determines an importance for each POI within a same category. The map item control forms a set of clusters of map items. Each map item in a given cluster of map items has a same cell and a same category. The map item control selects a top-item for each cluster of map items.Type: ApplicationFiled: July 6, 2022Publication date: March 21, 2024Applicant: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventors: DOUGLAS M. DYER, VERNER KEITH DEVLIN, WILLIAM R. SMITH

Publication number: 20230372702Abstract: In embodiments, a wearable cardiac defibrillation (WCD) system includes one or more flexible ECG electrodes. The WCD system may have a support structure that is dimensioned to be worn so as to press the electrodes towards the body of the patient. The electrodes may be made from appropriate material so as to flex in order to match a contour of the body of the patient. An advantage over the prior art is that the flexible electrode may make better electrical contact with the patient's skin, and therefore provide a better ECG signal for the WCD system to perform its diagnosis.Type: ApplicationFiled: July 21, 2023Publication date: November 23, 2023Applicant: West Affum Holdings DACInventors: William Edward Crone, Dallas Eugene Meeker, Robert Reuben Buchanan, Douglas Keith Medema, David Peter Finch, Laura Marie Gustavson, Daniel James Finney

Patent number: 11000692Abstract: Embodiments are directed to wearable cardioverter defibrillator (WCD) systems that include patient parameter electrodes, such as ECG electrodes, that are at least substantially electrically isolated from other circuits of the WCD system. In embodiments, the WCD system includes a power source, an energy storage module, and a processor each connected to a first circuit ground. A patient parameter sense port, such as an ECG port, is coupled to the patient. A measurement circuit may render a physiological input from the sensed patient parameter received at the patient parameter sense port, and the measurement circuit includes an isolating circuit that electrically isolates the patient parameter sense port from the first circuit ground. The sensing of physiological inputs of the patient can be improved, resulting in fewer erroneous readings and false alarms.Type: GrantFiled: June 16, 2019Date of Patent: May 11, 2021Assignee: West Affum Holdings Corp.Inventors: Douglas Keith Medema, Kenneth Frederick Cowan, Zhong Qun Lu
