A device that includes a piece of armor made from a material that has a domain of plastic deformation under bad before breaking and an elastic deformation domain. The plastic deformation domain represents less than 1% of the elastic deformation domain. The device includes a deformation sensor fixed to the piece of armor and configured to deform plastically under the effect of at least a stress applied to the piece of armor and leading to damage of the piece of armor.

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.

Sensing devices including sensors such as flexible and stretchable fabric-based pressure sensors, may be associated with or incorporated in garments, such as socks, intended to be worn against a body surface (directly or indirectly). Specific manifestations of a sensing system incorporated in a sock substrate are described in detail. Dedicated electronic devices interface electrically with sensors through intermediate conductive traces, optional conductive bridges, conductive contacts provided in a mounting tab.

A system for detecting forces on and measuring deformation of an anthropomorphic test device (ATD) includes a plurality of body parts and at least one optical fiber supported by and in contact with at least one of the body parts. The body parts form the ATD and simulate at least a part of a human body and the articulation of the human body. The optical fiber extends between a first end and a second end and comprises a plurality of sensors disposed between the ends. An emitter is in communication with the optical fiber for emitting a light having a predetermined band of wavelengths through the optical fiber that is reflected by the sensors and an interrogator is in communication with the optical fiber for detecting the reflected light from the sensor such that changes to the reflected light indicate a strain on the at least one body part.

A personal impact monitoring system is described herein comprising a monitoring station that receives impact events sent from personal impact monitors using a monitoring station receiver. The impact events which specify impact parameters associated with the impact events are stored in a data storage location associated with the monitoring station. Software operating on the operating station is configured to receive the impact events from the data storage location and to perform calculations based on the impact events to identify notable impact events.

A micromechanical device includes a semiconductor body, a first mobile structure, an elastic assembly, coupled to the first mobile structure and to the semiconductor body and adapted to undergo deformation in a direction, and at least one abutment element. The elastic assembly is configured to enable an oscillation of the first mobile structure as a function of a force applied thereto. The first mobile structure, the abutment element and the elastic assembly are arranged with respect to one another in such a way that: when the force is lower than a force threshold, the elastic assembly operates with a first elastic constant; and when the force is greater than the threshold force, then the first mobile structure is in contact with the abutment element, and a deformation of the elastic assembly is generated, which operates with a second elastic constant different from the first elastic constant.

A method determines damage which occurs on the vehicle in the event of an accident between a vehicle and a collision partner. The method analyzes information about an acceleration profile of the vehicle provided by an acceleration sensor. The analysis is performed as to whether the acceleration profile exhibits at least one sudden change or jump. The method generates an output signal which includes an item of information about damage which has occurred on the vehicle in the event of the accident, based on a number of changes or jumps which are identified during the analysis of the acceleration profile.

Impact testing apparatuses are disclosed which simulate and measure various impact-related events associated with the operation of a drug delivery device. The impact testing apparatus may include an impactor configured to simulate a plunger rod of the drug delivery device, and a guide sleeve configured to receive a syringe corresponding to the drug delivery device. The syringe may have a proximal end, a distal end defining an outlet, and an interior chamber extending between the proximal and distal ends and carrying a plunger. Additionally, the impact testing apparatus may include an energy source configured to reduce a distance between the impactor and the plunger so that the impactor strikes the plunger. Various sensors may be included to measure characteristics of one or more impacts caused by the impactor. Methods of impact testing a syringe filled with a fluid and carrying a plunger are also disclosed.

A collision detecting apparatus for a vehicle includes a bumper acceleration sensor, a floor acceleration sensor, a pressure sensor, and a processor including a vehicle collision determining unit and a threshold variably controlling unit. The vehicle collision determining unit is configured to determine a state of collision of the vehicle by comparing a detection value of the pressure sensor with a first threshold, and comparing a detection value of the bumper acceleration sensor with a second threshold when the detection value of the pressure sensor is greater than the first threshold. The threshold variably controlling unit is configured to change a threshold of the floor acceleration sensor from a third threshold to a fourth threshold in a case where: the detection value of the pressure sensor is greater than the first threshold; and the detection value of the bumper acceleration sensor is equal to or less than the second threshold.
