Abstract: A device monitors sensor data generated by movement of a wearer and determines whether the data indicates a fall. The device may include accelerometers, barometer(s), and sensors that detect, light, sound, temperature, magnetic and electric fields, strain-force on the device, and other environmental conditions. A processor determines whether the data meets a first criterion for a parameter (i.e., exceeding, an acceleration or barometric pressure maximum threshold). The first criterion corresponds to a first set of known-fall event data sets. If the first criterion is met, the processor generates a full indication. If the data does not meet the first criterion, the processor compares the data to a second criterion for the same, or different, parameter. If the second parameter is met, further processing confirms a fall determination by comparing the data to other criteria corresponding to known-fall event data sets that differ from the first set.

Abstract: An automatic control method of inflation is revealed. An inflator including a pressure gauge with a microprocessor automatically controls an inflated object to be inflated until the pressure reaches an initial set pressure value on the pressure gauge. After the pressure reaching the initial set pressure value, an air pump of the inflator is shut down until the pressure gets balanced. Now the value shown on the pressure gauge is lower than the initial set pressure value. The difference between an actual pressure value and the initial set pressure value is calculated and is added with the initial set pressure value to get a new set pressure value the inflated object actually needs by the microprocessor. Now the inflator starts inflation again until the pressure reaches the new set pressure value. The inflation is completely precisely.
