An elderly care and security system comprises one or more networked lighting luminaire installed in a room, the luminaire comprising: one or more sensors configured to: detect a fall; detect smoke; detect glass break; detect presence of another person in the room while the elderly person is lying in bed; and detect presence of a person while an alarm system is active and detect no presence for a period longer than a predetermined time interval; a lighting unit controlled to adaptively illuminate the room; a wireless bi-directional transceiver, loudspeaker and microphone, configured to be activated automatically for communication with the elderly person, a caregiver or relative; a door locking/unlocking unit with connectivity to an electrical door lock, configured to automatically lock/unlock a door of a safe room for the elderly person; and an alarm activating unit, configured to automatically activate/deactivate an alarm.

Systems and methods for monitoring elevations of a set of workers at a job site include reference devices for capturing barometric pressures at different installation elevations on a structure and portable barometric pressure sensors carried by the workers. An atmospheric pressure offset may be calculated using the reference barometric pressures and installation elevations. The atmospheric pressure offset may be applied to atmospheric pressure measurements captured by the barometric pressure sensors carried by the workers to determine worker elevations. The worker elevations may be converted to corresponding floors of the structure.

A Swimguard protection system for detecting a person in distress in a body of water includes one or more sensors directed at the body of water, an alarm system configured to sound an audible alarm if a person is detected to be in distress, and a computing device in electrical communication with the one or more sensors and the alarm system. The computing device is configured to execute a deep learning algorithm that detects an event indicative that a person is in distress in the body of water. Characteristically, the computing device is further configured to send a trigger to the alarm system to provide an audio alarm upon the detection of such an event.

Breathing naturally produces CO.sub.2, which means that the presence of people or animals inside the passenger compartment of a vehicle can be detected. In the presence of at least one occupant, in as little as five minutes, the concentration of carbon dioxide can become dangerous. To remediate high concentrations of carbon dioxide within the passenger compartment, a warning is provided that instructs any occupant to start the vehicle. Should the vehicle not be started within a predetermined period of time after the warning, certain automatic remediation actions are taken, provided that the battery of the vehicle retains enough power to start the vehicle. If the automatic remediation actions fail to lower the levels of carbon dioxide, then all available power is utilized to reduce the levels of carbon dioxide and to bring assistance to the occupants of the vehicle.

Method and apparatus for monitoring the status and location of personnel using a remote timer. In some embodiments, a method includes execution of a subject application (app) on a network accessible device. A countdown timer of a remote server is initiated to monitor a time interval, the remote server communicating with the network accessible device over a network. Geo positions of the network accessible device are monitored during the monitored time interval. The remote server sends a notification to a monitoring device responsive to at least one of the following events: the monitored time interval ends without the remote server receiving an authorized personal identification (PID) value; or the remote server receives an unauthorized PID value prior to the conclusion of the monitored time interval. In further embodiments, a notification is sent based on an out-of-bounds geo position of the network accessible device during the time interval.

Systems, devices, and methods including a computing device with a processor configured to: send a keep-alive signal to a user at a predefined interval; determine an active status of the user if a reply to the keep-alive signal is received prior to an expiration of the predefined interval; determine a non-active status of the user if a reply to the keep-alive signal is not received prior to an expiration of the predefined interval; send a first level transition notification to a first contact list if the determined status of the user is non-active; send a second level transition notification to a second contact list after a first time period has expired and the reply to the keep-alive signal is not received; and send a third level transition notification to a third contact list after a second time period has expired and the reply to the keep-alive signal is not received.

A help-seeking method and system for indoor care are provided. A presentation information code is obtained through the acquired human body presentation information in each preset height section, and a help-seeking message is generated when a duration in which the presentation information code matches a target code is greater than a time threshold corresponding to the target code. All possible behavioral postures of a human body in daily activities are converted into and represented by respective target codes, and the target codes are associated with time and preset in the system. By recording duration in which the human body presentation information code for an elder during indoor activities matches the corresponding target code, a help-seeking message can be generated for an abnormal situation in which the duration of a behavioral posture is greater than the time threshold for the matched target code.

A management system includes, a sensor configured to detect biological information on a user, a communication unit capable of communicating with a terminal device and capable of receiving the biological information, a controller configured to detect whether the user is awake or gets out of the bed, based on the received biological information and activate an alarm to the terminal device, and a display configured to prioritize the alarm related to the user which has a high possibility of falling off the bed.

A distributed type traffic line tracing apparatus of the present disclosure is personally installed in a residence of a tracing target person, to automatically verify whether a traffic line of the tracing target person coincides with a traffic line of a confirmed person and automatically report a result to a disease management authority only when the traffic lines coincide with each other in an emergency situation such as an infectious disease pandemic, so that a quarantining target person is discovered and found early while protecting a privacy of an individual much more when compared to a centralized type, thereby rapidly establishing an infectious disease management system for patients with suspected diseases and efficiently managing the patients from the spread of infectious diseases.

The present invention relates to: a device and method for assessing the risk of lonely death using a door open sensor; and a LED system for assessing the risk of lonely death. More specifically, the device for assessing the risk of lonely death using a door open sensor, according to one embodiment of the present invention, comprises: a door open recognition unit which recognizes that a door has been opened; an outside activity time calculation unit which, when the door is recognized to have been opened, and activity of a human body is not detected from the time point when the door is recognized to have been opened to a predetermined time, determines an outside activity state and calculates an outside activity duration which is the time during which the outside activity state is maintained; an inside activity time calculation unit which, when activity of the human body is detected at a first time point, and activity of the human body is detected again at a second time point which includes an idle detection period after the first time point, determines an inside activity state and calculates an inside activity duration which is the time during which the inside activity state is maintained; and a risk assessment unit which assesses the risk of lonely death by generating a probability distribution model on the basis of the outside activity durations and inside activity durations calculated during a first period, and applying, to the probability distribution model, the outside activity duration and inside activity duration calculated after the first period.
