A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

A method operates a device arranged on or in a mobile motor-driven processing device, wherein the device has an inertial sensor device with at least one inertial sensor formed for detecting an inertial variable and a control device. The method has the following steps: a) operating the inertial sensor device in a motion-monitoring operating mode to monitor whether the inertial variable or a variable based on the inertial variable fulfills the motion criterion, wherein the motion criterion is characteristic of a motion of the processing device, b) if the motion criterion is fulfilled, operating the inertial sensor device in a shock and/or impact-monitoring operating mode to monitor whether the inertial variable or a variable based on the inertial variable fulfills a shock and/or impact criterion, wherein the shock and/or impact criterion is characteristic of an atypical motion of the processing device, and c) if the shock and/or impact criterion is fulfilled, transmitting an information signal via the inertial sensor device and operating the control device as a function of the transmitted information signal.

A method for operating an infrastructure sensor system, wherein the infrastructure sensor system comprises a plurality of networked infrastructure sensors arranged on a shared mounting device. First, data are transmitted to a sway estimation module by at least one of the infrastructure sensors, wherein the data comprise at least pre-processed data, for example environmental information and/or current measurement data, in particular raw data, detected by the respective infrastructure sensor. The transmitted data are further processed in the next step and the sway estimation module determines therefrom a motion function for the mounting device. Based on the motion function, correction information, for example for at least one of the infrastructure sensors, is now determined by the sway estimation module. The correction information and/or motion function can now be provided for further use, for example, to the respective infrastructure sensors or to a central computing unit.

An impact indicator includes a housing configured to enable movement of a mass member from a first position to a second position in response to receipt by the housing of an acceleration event. The indicator also includes switch circuitry having a compressible switch element positionable between spaced apart contacts where the switch element is configured to be in spaced apart relationship to the mass member. A passive radio-frequency identification (RFID) module is coupled to the switch circuitry and, responsive to movement of the mass member from the first position to the second position, the mass member causes a positional change of the switch element relative to the first and second contacts, and the positional change causes a state change in the switch circuitry. The RFID module outputs a value based on the state of the switch circuitry when energized.
