A method for classifying a response signal of acceleration data of a structure includes obtaining at least one signal feature of a response signal, inputting the at least one signal feature into an artificial neural network, and classifying, using the artificial neural network, the response signal as an impact event or a non-impact event. One or more signal features may be used, including a response length feature, a number of peaks feature, a spectral energy feature, a dominant frequency feature, a maximum response feature, a center of mass feature, a slope feature, an average peak power feature, a response symmetry feature, or combinations thereof. One or more artificial neural networks may be used. The artificial neural networks may be trained using different combinations of signal features.

An impact detection system for a vehicle and an impact detection method therefore are provided. The impact detection system includes an impact value calculator that determines an impact value corresponding to a magnitude of an impact applied to a vehicle, an impact location estimator that estimates a location to which the impact is applied in the vehicle and generates an impact location signal including a parameter value corresponding to the estimated location, and an effective impact determining device that compares the impact value with an impact detection reference value for each location of the vehicle, corresponding to the parameter value.

An example computing device includes a motion sensor to detect movement of a computing device. The computing device also includes an example processor to 1) determine a rate of movement change of the computing device and 2) activate an impact sensor of the computing device responsive to the determined rate of movement change being greater than a threshold rate. The example computing device includes an impact sensor to detect an impact of the computing device and record data associated with the impact.

A control system for a screen of a vehicle includes a global positioning system (GPS), an inertia sensor and a control circuit. The GPS detects a satellite signal from a satellite. The inertia sensor senses motion of the vehicle and correspondingly generates a motion state value. The control circuit performs one of a first determination procedure and a second determination procedure according to the state of the satellite signal. In the first determination procedure, the control circuit calculates the vehicle speed of the vehicle according to the satellite signal, and selectively locks the screen of the vehicle according to the vehicle speed. In the second determination procedure, the control circuit generates a motion signal according to the motion state value, and selectively locks the screen of the vehicle according to the motion signal. Accordingly, driving safety can still be effectively ensured even in the case of poor satellite signals.

Accelerometers are described herein that have RMS outputs. For instance, an example accelerometer may include a MEMS device and an ASIC. The MEMS device includes a structure having an attribute that changes in response to acceleration of an object. The ASIC determines acceleration of the object based at least in part on changes in the attribute. The ASIC includes analog circuitry, an ADC, and firmware. The analog circuitry measures the changes in the attribute and generates analog signals that represent the changes. The ADC converts the analog signals to digital signals. The firmware includes RMS firmware. The RMS firmware performs an RMS calculation on a representation of the digital signals to provide an RMS value that represents an amount of the acceleration of the object.

A racking protection device that includes a housing and vibration monitor. The vibration monitor is arranged to record the vibration transmitting through a racking component. The housing includes an alert for alerting a user when the racking requires inspection for damage to impacts. The vibration monitor records the frequency and time of each impact. The vibration monitor includes a memory that counts and records the number of minor impacts. The vibration monitor determines a minor impact when the peak frequency is between a minimum and maximum pre-set level for a predetermined time period. When a predeteiiiiined number of minor impacts is exceeded, the alert is arranged to alert the user to inspect the racking for damage. When the frequency exceeds the maximum pre-set level for a predetermined time period the vibration monitor determines that a severe impact has occurred and the alert is arranged to alert the user to inspect the racking for damage.
