摘要:
Briefly, an alarm system monitors conditions of an independent person, yet one requiring some supervision, such as an elderly person living alone at home. The system monitors a variety of independent signals and combines them to recognize subtle cues that may indicate there will be a need for intervention by a supervisor.

An abnormality detection apparatus for detecting an event where a monitored object in a room has lapsed into an abnormal state, the apparatus including image pickup means for picking up an image of a scene in the room, feature-quantity extraction means for extracting an image feature quantity from the image picked up by the image pickup means, judgment means for determining whether the monitored object in the room has lapsed into the abnormal state or not based on the time-variations of the image feature quantity extracted by the feature-quantity extraction means, and means for outputting an alarm responding to the determination of the occurrence of the abnormal state.
摘要:
A method and apparatus for monitoring a human or animal subject in a room using video imaging of the subject and analysis of the video image to detect and quantify movement of the subject and to derive an estimate of vital signs such as heart rate or breathing rate. The method includes techniques for decorrelating global intensity variations such as sunlight changes, compensating for noise, eliminating areas not of interest in the image, and quickly and automatically finding regions of interest for detecting subject movement and estimating vital signs. A logic machine is used for interpreting detected movement of the subject, and an artificial neural network is used to calculate a confidence measure for the vital signs estimates from signal quality indices. The confidence measure may be used with a normal density filter to output estimates of the vital signs.
摘要:
A method and apparatus for monitoring the health and safety of a subject in a room such as a secure room based on video images of the subject. The images are analysed to characterise the movement of the subject as gross movement, fine movement or no movement. In the case of gross movement, no vital signs of the subject are estimated and a display indicates that the subject is moving, but no vital signs are available. In the absence of gross movement, vital signs of the subject such as heart rate or breathing rate are estimated from the video images of the subject, for example by detecting and analysing photoplethysmogram signals in the video images, and the vital signs are displayed. Alerts may be generated if the vital signs are out of the normal physiological range. If vital signs cannot be detected in the video images but the movement of the subject is characterised as fine movement, the display shows that no vital signs are being estimated, but that the subject is moving. If no movement is detected and no vital signs estimate is obtained, then the display generates an alert indicating lack of movement and lack of vital signs.

The method and apparatus utilize communication devices and systems and/or Internet of Things (IoT) devices and systems to track a person's user interaction events, store them, and process the individual events or the accumulated history of these events for computing and generating an indicator of the level of user isolation for the tracked individual. During the monitoring and processing of the events, when the generated indicator meets or exceeds a predetermined value, an alert can be generated to notify the individual's friends, relatives, associates, or other identified persons to initiate contact with the senior.

In a display device, a display method, and a subject observation system according to the present invention, when a sensor unit inspects a predetermined movement of a subject to be observed, a display device receives a new inspection result about the inspection from the sensor unit via a central processing apparatus. In this case, the display part displays a code representing a presence of the new inspection result having been received, while maintaining an existing display content being displayed thereon, and further displays the new inspection result having been received on the display part when an input part receives a change instruction input.

Provided is a motion detection system capable of alleviating a burden on a caregiver which could arise when a plurality of types of notification target motions is detected during a short time period. A motion detection system (300) includes: an acquisition unit (52) for acquiring motion data indicating a motion of a person; a detection unit (150) for detecting a predetermined motion of the person using the motion data; a selection unit (160) for, when a plurality of types of output candidate motions is detected by the detection unit (150) during a predetermined time period, selecting an output target motion from among the output candidate motions such that types of the output candidate motions are made fewer than the plurality of types; and an output unit (170) for outputting the output target motion selected by the selection unit (160).
摘要:
A position identifying unit (4) is configured to identify the location of a monitored person in the horizontal direction and maximum height of the monitored person in the vertical direction on the basis of top-down image data acquired by an upper image sensor (2) provided above a monitored area capturing an image of the monitored area and lateral image data acquired by a lateral image sensor (3) provided along a side of the monitored area capturing an image of the monitored area. An event determining unit (5) assesses a fall-related event for the monitored person on the basis of a location in the horizontal direction, a maximum height in the vertical direction.
