Sensor apparatus and methods for operating the same for measuring acceleration are disclosed. In some embodiments, circuitry inside a sensor digitizes a measured acceleration signal from an accelerometer into a digitized acceleration signal, which is processed by a digital equalization filter within the sensor to provide an equalized acceleration signal. The equalized acceleration signal may have a frequency response that is substantially flat over a frequency range that extends beyond the resonant frequency of a MEMs sensor within the accelerometer of the sensor.

An anti-motion sickness device fitted to a motor vehicle including a triaxial accelerometer to detect the vehicle accelerations along three axes and to emit a corresponding acceleration signal; a display component of light markers to form at least one first and second artificial horizon lines at first and second inner surface, respectively of the motor vehicle. The device includes a control unit for receiving the acceleration signals and for driving the display wherein the artificial horizon lines are aligned in a horizontal plane perpendicular or substantially perpendicular to the gravity vector regardless of vehicle accelerations. The control unit is configured to process the acceleration signals, prior to the control of the display to determine in real time an acceleration frequency according to each of the accelerometer axes and to drive the display only when the acceleration frequency is below a threshold frequency, below which the motion sickness likely occurs.

Measuring device / sensor system for measuring, transferring and processing of relevant performance data from training and competition in contact sports, in particular the physical contact and its force effect

In practice and as far as possible, performance data in contact sports, in particular those of factual contact and force effect of relevant objects and persons to each other, are not surveyed separately but evaluated subjectively. In contact sports like martial arts this is especially critical, because an occurred contact and its force effect are the significant success data in these sports. In other types of contact sports, e.g. ball sports one is concentrated on the performance data, that lead to goal achievement (e.g. goal scoring) and is not looking objectively into the performance of participants for, for example, draw conclusions about the correct technique execution at any time in a game or competition. Though there are already measuring devices for some contact sports for detecting force effect and contact, these are limited to several defined single sensors and applications. Therefore it may be possible to make objective measurement but in case of doubt, a subjective evaluation of technique and point assignment is still necessary. This invention contains a system of measuring devices, that can, especially in martial arts sports, improve the point assignment and in other contact sports the evaluation of techniques. These special measuring devices for contact measuring and its movement and acceleration sensors, display systems and hardware interfaces can be combined with software interfaces and be tailored to fit different applications. In case of martial arts sports, the configuration of protective equipment with these measuring devices is one use case, in which the measuring devices detect all relevant data like contact, force effect and movement direction, that can be used for competition decisions.

A method may include obtaining sensor data describing a total measurable world around a motion sensor. The method may include processing the sensor data to generate a pre-compensation scan of the total measurable world around the motion sensor based on the sensor data. The method may include determining a delay between the obtaining the sensor data and the generation of the pre-compensation scan. The method may include obtaining motion data corresponding to motion of the motion sensor and generating a motion model of the motion sensor based on the motion data. The method may include generating an after-compensation scan of the motion sensor using the delay and the motion model to compensate for continued motion during the delay.
