Abstract: A significant number of rescue workers are killed or injured each year as they conduct searches within damaged or burning structures, unaware that the structure is unstable. The present invention provides a system and method for real-time detecting and monitoring structural instability that may lead to inevitable collapse of a structure. The system is capable of displaying data, including visual and/or audible signals, indicating structural instability. Additionally, the present invention is also directed to stability monitoring analysis processes for determining structural stability or instability.

Abstract: The portable ventilator of the present invention provides a hands-free ventilatory support device in critical care, emergency, and resource-limited environments. The portable ventilator utilizes ambient air and includes a two dual head compressor system to provide a consistent air supply to the patient. The ventilator device is battery operated and is capable of providing up to 60 minutes of care. In a preferred embodiment, the portable ventilator of the present invention also includes a pneumatic subsystem, a control subsystem, a power subsystem and an alarm subsystem. The portable ventilator of the preferred embodiment includes a dual head and single head compressor system that operates alternatively, to provide a consistent and continuous inhalation and exhalation cycle. A portable ventilator of a second preferred embodiment includes a sole dual-head compressor that operates to provide a consistent and continuous inhalation and exhalation cycle.

Abstract: The present invention focuses on a method and device for noninvasively measuring cardiac output at a distance, without direct contact to the patient using stepped frequency electromagnetic interrogation. The method detects cardiac versus non-cardiac activity by quantifying the changes in the dielectric properties of blood as it goes through the heart.

Abstract: A significant number of rescue workers are killed or injured each year as they conduct searches within damaged or burning structures, unaware that the structure is in imminent danger of collapse. The present invention provides a system and method for detecting and monitoring structural damages which are irreversible and which lead to inevitable collapse of a building or structure. The system includes at least one accelerometer that is housed in a device that is mounted on an exterior surface outside the burn area, and within the reach of the rescue worker. The device communicates with a remote display that provides visual and/or audible signals to indicate imminent collapse of the structure. Additionally, the system includes collapse detecting analysis processes for determining the likelihood of collapse.
