Disclosed herein are apparatuses and methods for providing evacuation guidance. An implementation may comprise identifying a person physically present in an environment requiring an evacuation. The implementation further includes detecting, using at least one sensor in the environment, a last known location of the person. The implementation further includes calculating an exit time for evacuating the environment based on the last known location. The implementation further includes monitoring, using at least one sensor located at an egress point of the environment, whether the person has evacuated the environment. The implementation further includes determining whether a current time has passed the exit time. The implementation further includes transmitting an alert to a device of the respective person in response to determining that the current time has passed the exit time and that the person has not evacuated the environment.

A reminder device includes a frame-shaped base defining an opening and configured to be mounted over and around an operational button/handle located in a vehicle or in a home; a lid coupled to the frame-shaped base and configured to close over said frame-shaped base, covering said opening and blocking access to said operational button/handle; a circuit configured to product an audible message upon receiving a trigger signal, said circuit being located in at least one of said framed-shaped base and said lid; and a switch including a first component located on said frame-shaped base and a second component located on said lid and so configured that when said first component and second component are separated from each other by a predetermined distance, when the lid is opened, the switch causes the creation of said trigger signal and the production of said audible alarm.

A proximity warning system including cameras positioned on a machine, processors, and one or more memory devices including instructions for execution by the processors. The system includes instructions to receive, from the cameras, image data depicting an object within a field of view of the cameras. The system includes instructions to derive a first distance between the object and the machine based on the image data and an alarm is triggered when the first distance is less than a first threshold distance. The system can include instructions to receive a request to snooze the alarm and discontinue the alarm. Additional image data can be received from the cameras and a second distance between the object and the machine is derived based on the additional image data. The system includes instructions to cancel the snooze and retrigger the alarm when the second distance is less than a second threshold distance.

Input data, such as audio and/or video data, may be captured from a first room, for example via microphones and/or cameras within the first room. A first quantity of people within the first room may be determined based at least in part on the input data. An alert may be provided when the first quantity of people exceeds a threshold quantity of people. Additionally, locations of people within the room may also be detected based at least in part on the input data. A first proximity of a first person in the room to a second person in the room may be determined. An alert may also be provided when the first proximity is less than a threshold proximity.

A collision prevention system for lifting machinery including, at least one measurement transceiver (9, 39, 41, 45) mountable on or adjacent the lifting machinery, the measurement transceiver being adapted to transmit a radio signal through an operational area surrounding the lifting machinery, and for measuring reflected radio signals returning from the operational area, the reflected radio signals identifying a position of one or more objects located within the operational area to thereby determine whether or not the detected object(s) within the operational area is within a critical position(s) relative to the lifting machinery.

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.
