Abstract: A tilt protection apparatus applied to electric energy generating installations, where possibility of tilting or tipping over exists. In certain installations of electric energy generating facilities, the means of energy production, such as but not limited to solar photovoltaic panels, must be mounted on support system that can be susceptible to mechanical failure due to impact, wind induced vibration, ground vibration or ground displacement. In the event of the structural tilt, the apparatus detects such condition and disconnects the means of energy generation minimizing possibility of exposure to dangerous levels of electric potential.

Abstract: A nuclear cardiology system for use with a scintillation camera for evaluating cardiac function by real time measurement of the variation of radiation from the heart of a patient to whom is administered a radioactive tracer. The camera provides data describing the location of individual counts representing radiation events coming from the patient. The system segregates, in real time, counts corresponding to radiation from an electronically defined region of interest describing an investigated part of the heart, such as the left ventricle. Synchronized by the patient's electrocardiogram, time gated memory circuitry divides each heartbeat into a series of subintervals, and stores indications of the respective amounts of radiation events emanating from the region of interest during each of the subintervals.
