A battery system for a vehicle includes a battery pack having a structure defining a chamber receiving a battery. A first sensor is mounted to the structure for sensing an operating condition within the chamber. A safety module is disposed outside of the chamber. The safety module processes signals received from the first sensor to identify if the operating condition defines an abnormal condition occurring within the chamber. The safety module sends a first safety module signal when the signals received from the first sensor indicate the abnormal condition is present within the chamber.

An automatic smoke/carbon monoxide evacuation system for a building having at least one existing ventilation fan and at least one ventilation passageway to outside the building is provided. The system includes a microprocessor and a smoke/carbon monoxide sensor coupled to the microprocessor and configured to detect presence of smoke/carbon monoxide and send a trigger signal to the microprocessor in response to detecting smoke/carbon monoxide. A power switch is coupled to the existing ventilation fan and is configured to automatically connect the existing ventilation fan to a power source in response to the trigger signal, so that the ventilation fan rotates at a high speed to ventilate the detected smoke/carbon monoxide via the existing ventilation passageway. An alarm device is further communicably coupled to the microprocessor and is configured to issue an alarm in response to the trigger signal.

An automatic smoke/carbon monoxide evacuation system for a garage equipped with a garage door and garage door opener with a motor is provided. The system includes a microprocessor, and a smoke/carbon monoxide sensor incorporated in a garage door reverse sensor of the garage door opener and coupled to the microprocessor, and configured to detect presence of smoke/carbon monoxide and send a trigger signal to the microprocessor in response to detecting smoke/carbon monoxide. The system further includes a power switch coupled to the motor and configured to automatically connect the motor to a power source in response to the trigger signal to automatically open the garage door to ventilate the detected smoke/carbon monoxide in response to the trigger signal. An alarm device is communicably coupled to the microprocessor and is configured to issue an alarm in response to the trigger signal.

Methods, systems, and products monitor environmental conditions in an enclosed environment, such as a garage or storage shed. If a dangerous environmental condition is determined, such as elevated carbon monoxide, an entry door may be opened. If further remedial measures are required, ignition of an internal combustion engine may be prohibited.

Garage door openers and methods of operating garage doors to reduce the risk of carbon monoxide poisoning. Such a garage door opener includes a motor unit configured to raise and lower an overhead garage door of a garage functionally coupled thereto, and an carbon monoxide (CO) detector that detects and measures a concentration of carbon monoxide gas in the garage. The CO detector directly delivers a signal to the motor unit in response to the detected concentration of carbon monoxide gas exceeding a predetermined CO threshold level for at predetermined duration, so that the garage door opener raises the overhead garage door with the motor unit.

In one embodiment, an electronically controlled hatch system for safe ingress, egress, hazard detection, and methods thereof are provided to reduce or eliminate hazards to personnel, including protection of people above and below a scuttle hatch, access port, skylight or elevated deck. Said hatch system reduces the risk of falls while ascending or descending a ladder through an access port. In certain embodiments, severe weather, hazard, security, and other safety information are detected and transmitted to a central control unit for processing and regulating the opening and closing of a hatch covering the access port and/or raising and lowering a safety railing system based on said information and/or user input. Said hatch system may include an actuator and guides for automatically locking/unlocking and opening/closing a hatch, an actuator and guides for automatically raising/lowering a railing system, safety monitoring detectors/apparatuses, and a centralized controller.

An automatic garage door safety system includes a drive assembly, a detection assembly, a control unit, and a housing. The drive assembly includes a motor and a mechanical arm assembly designed to operatively connect the motor to a garage door. The detection assembly is designed to detect an atmospheric condition in a room openable and closable by a garage door. The control unit is operatively connected to the motor and the detection assembly and designed to activate the motor to open a garage door upon receiving information from the detection assembly indicating an atmospheric condition hazardous to humans. The housing contains the motor, the detection assembly, and the control unit.
