A sealed enclosure power control system for controlling power to an electrical component within an enclosure. The sealed enclosure power control system generally includes an electrical component within the sealed enclosure, a first connector on the sealed enclosure adapted to provide a sealed electrical interface to the electrical component. The first connector has at least one first connector conductor element, and the system further includes a battery within the sealed enclosure, and the system also has a second connector, wherein when the first connector and the second connector are connected together, electrical power from the battery is applied to the electrical component, and when the first connector and the second connector are not connected together, the electrical power is not applied to the electrical component.

A fire detection device includes a vented detector housing, with an opening defined in a mounting base. A substance exhaust channel in air flow communication with the opening extends upward from the mounting base. A pressure release turbine includes an impeller operatively disposed in the channel. A rotation sensor senses rotation of the impeller and generates an alert upon detection of a heat level indicated by rotation of the turbine rotor at a predetermined speed. A high pressure and/or heat louver disposed over the opening opens in response to a predetermined heat level. An actuator detects opening of the louver and generates an alert. A thermostatic device disposed in the housing senses, and generates an alert at, a predetermined heat level. A thermal imaging device disposed in the housing senses, and generates an alert at, a predetermined heat level.

The present invention relates to a method for contactlessly measuring the amount of menstrual blood in a menstrual cup. The amount of menstrual blood that has been stored in a menstrual cup can be simply measured by using a contactless sensor means, thereby enabling the user to periodically check the amount of menstrual blood. This enables early detection and treatment of uterine fibroid, which may even lead to hysterectomy.

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.
