In a system and method for detecting carbon dioxide in an enclosed volume, a CO2 detection system is triggered to awaken from a deep sleep state. Once awake, the system queries system sensors to determine the current system parameters, including current CO2 level and temperature. Current and expected CO2 decay rates are calculated, and the system determines whether the current CO2 decay rate is within an expected normal range for an unoccupied enclosed volume. If the volume is static, i.e., not moving, and the CO2 rate is rising and the temperature is rising, a series of alerts are sent to contacts previously set up by the user. If the alerts are not cleared by a user, emergency management personnel are notified.

The present invention provides a processing apparatus (10) including an acquisition unit (11) that acquires a capture image capturing a movement means, an image analysis unit (12) that computes, based on the capture image, the number of persons each having an attribute satisfying a first criterion among persons inside the movement means, and the number of persons targeted for comparison, a computation unit (13) that computes a ratio of the number of persons satisfying the first criterion to the number of persons targeted for comparison, and an output unit (14) that outputs alert information when the ratio satisfies an alert condition.

A device for detecting household conditions and events includes a power supply portion and a plurality of portions able to detect different conditions, or changes in different conditions. Each detecting portion includes an input port and an output port, the output port of one detecting portion is detachably electronically connected to the power supply portion, and the input port of one detecting portion is detachably electronically connected to the output port in a modular fashion of another detecting portion, the remote selection of a specific required detection is also provided.

A system for physical-distancing detection in a specified area includes a locator locating a positioning quadrangle plane in a specified area; an image-capturing device obliquely capturing an image of the specified area to generate a captured image of the specified area; and a coordinate converter defining a coordinate conversion function according to raw coordinates of selected points of the positioning quadrangle plane in the captured image of the specified area and reference coordinates of the selected points of the positioning quadrangle plane in an overlooked image of the specified area. The image-capturing device converts raw coordinates of the captured image of the specified area into converted coordinates of the overlooked image of the specified area by way of the coordinate conversion function, determines a physical-distancing condition between two persons according to the converted coordinates, and automatically takes an action corresponding to the physical-distancing condition.

A method for predictive analysis for maintaining a battery charge of a personal monitoring device is provided. The method includes: locking the personal monitoring device to a limb of a monitored person; collecting historical information about the personal monitoring device including movement data of the personal monitoring device and battery charging history of the personal monitoring device; analyzing the collected historical information for patterns of battery charging behavior; receiving a current location of the personal monitoring device; determining whether to send a battery charge reminder to the monitored person, based on at least a current location of the personal monitoring device, a current batter charge, and the patterns of battery charging behavior; and providing, in response to a positive outcome of the determining, a notification to the monitored person to charge the battery.

A child safety seat includes a first and a second restraining device, and an alert device and a first and a second switch serially connected in a series circuit. Each of the first and second restraining device is deployable to engage with a corresponding structure provided in a vehicle, each of the first and second restraining devices being operable independently and having an idle position and a deployed position. The first and second switches are respectively coupled operatively to the first and second restraining device, and are respectively closed when the first restraining device is in the deployed position and the second restraining device in the idle position. The alert device is thereby activable to emit an alert signal when the first restraining device is in the deployed position and the second restraining device in the idle position.

An alert system includes an in-vehicle object detector and an alert controller. The in-vehicle object detector detects objects in a vehicle compartment, including an occupant. The alert controller is configured to control execution of alert output operations if the occupant is left in the compartment after the vehicle's driver has left the vehicle. The alert output operations include at least an output operation of an alert to a mobile terminal of the driver. The alert controller is configured to cause the in-vehicle object detector to begin a detection processing for detecting the occupant being left in the compartment if the driver has left the vehicle, determine whether the mobile terminal of the driver is left in the compartment, and switch between the alert output operations in accordance with whether the mobile terminal of the driver is left in the compartment.

A vehicle-interior monitoring apparatus for a vehicle includes a millimeter-wave sensor, a determiner, and a movement sensor. The millimeter-wave sensor outputs a millimeter radio wave toward a vehicle cabin of the vehicle and detects a millimeter reflection wave from an in-vehicle object including either one of an occupant and baggage in the vehicle cabin. The determiner determines a type of the in-vehicle object based on a detection level of the detected millimeter reflection wave. The movement sensor detects movement of the vehicle. The determiner re-determines that a determined in-vehicle object is either one of the baggage and a child as the occupant based on a positional change of the determined in-vehicle object upon the movement sensor detecting the movement of the vehicle, the determined in-vehicle object being the in-vehicle object of which the determiner has determined the type based on the detection level of the millimeter reflection wave.
