Patent number: 10645346Abstract: Various embodiments concern video patient monitoring with detection zones. Various embodiments can comprise a camera, a user interface, and a computing system. The computing system can be configured to perform various steps based on reception of a frame from the camera, including: calculate a background luminance of the frame; monitor for a luminance change of a zone as compared to one or more previous frames, the luminance change indicative of patient motion in the zone; and compare the background luminance to an aggregate background luminance, the aggregate background luminance based on the plurality of frames. If the background luminance changed by more than a predetermined amount, then the aggregate background luminance can be set to the background luminance, luminance information of the previous frames can be disregarded, and motion detection can be disregarded.Type: GrantFiled: January 17, 2014Date of Patent: May 5, 2020Assignee: CareView Communications, Inc.Inventors: Matthew Cameron Clark, Derek del Carpio

Patent number: 10390738Abstract: Various patient monitoring systems can include a sensor configured to collect three dimensional information. The systems can identify a location of a patient support surface based on the three dimensional information. The systems can set a two dimensional planar threshold based on the patient support surface. The systems can identify a patient location above the patient support surface based on the three dimensional information and compare the patient location to the two dimensional planar threshold. Exceeding the threshold can be indicative of a high risk of a patient fall. An alert can be generated based on the threshold being exceeded. The systems can repeat the identification of the patient support surface location and the setting of the threshold to account for changes in the patient area.Type: GrantFiled: July 10, 2018Date of Patent: August 27, 2019Assignee: CareView Communications, Inc.Inventors: Matt Clark, Derek del Carpio, Kenneth Chapman

Patent number: 10387720Abstract: A video monitoring system captures image frames of a patient in various positions. The captured image frames are analyzed by the system for changes in a patient's position or movement, frames in which the system detects one or both of patient movement and repositioning are retained. The system analyzes an area of interest within each image frame that corresponds to an area in the camera's view field with the patient. Sequential image frames are compared for motion, only frames without motion, where the patient is still, are analyzed.Type: GrantFiled: February 24, 2014Date of Patent: August 20, 2019Assignee: CareView Communications, Inc.Inventors: Steven Gail Johnson, Matthew Cameron Clark, Stephen Ecker, Kyle Brook Johnson, Richard Craig Kuether

Patent number: 10372873Abstract: The local surveillance sub-system recognizes that a patient medical procedure has or will soon commence by sensing the presence of a healthcare professional in or near the surveillance area, and in response, creates a separate patient medical procedure A/V file for the surveillance data that will be captured. A dedicated procedure remote may be provided for receiving manual interactions from HC professionals present for a procedure or, alternatively, the local surveillance sub-system may autonomously interact with a personal security token device possessed by the HC professional. A procedure data file is also created that holds all of the pertinent information concerning the procedure that is known by the local surveillance sub-system. The patient procedure surveillance A/V file is given a higher priority than ordinary surveillance data captured by the local surveillance sub-system and is then copied to a nonvolatile memory.Type: GrantFiled: March 14, 2014Date of Patent: August 6, 2019Assignee: CareView Communications, Inc.Inventor: Steven Gail Johnson

Patent number: 9311540Abstract: A patient fall prediction system receives video image frames from a surveillance camera positioned in a patient's room and analyzes the video image frames for movement that may be a precursor to a patient fall. In set up phase, the viewpoint of the camera is directed at a risk area associated with patient falls, beds, chairs, wheelchairs, etc. A risk area is defined graphically in the viewport. The patient fall prediction system generates a plurality of concurrent motion detection zones that are situated proximate to the graphic markings of the risk areas. These motion detection zones are monitored for changes between video image frames that indicate a movement. The pattern of detections is recorded and compared to a fall movement detection signature. One fall movement detection signature is a sequential detection order from the motion detection zone closest to the risk area in the frames associated with patient falls, to the motion detection zone farthest away from the risk area.Type: GrantFiled: May 6, 2008Date of Patent: April 12, 2016Assignee: CAREVIEW COMMUNICATIONS, INC.Inventors: Stephen Ecker, Kyle Brook Johnson, Steve Gail Johnson
