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.

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 inertia detection device includes one set of gyro sensors for detecting an angular velocity of a detection target object along a same direction, the gyro sensors arranged in a same physical quantity range, in which sensor movement is detectable as a same physical quantity. When an abnormality affecting an output signal of one of the gyro sensors is caused, based on an observation that a difference of magnitudes of the output signals from normal and abnormal gyro sensors is different from a difference of magnitudes of the output signals from two normal gyro sensors, such an abnormality of one of the gyro sensors is determinable by a comparison between the output signals, without using an estimated value thereof.

A method for increasing fail-safe operation of an industrial input/output assembly, wherein an external mechanical load that acts on the input/output assembly is determined via an acceleration sensor, where a check is performed to determine whether the load exceeds a predeterminable limit value and, if this is the case, a value of a load sum is then accordingly increased corresponding to an extent to which the value is exceeded, where the load sum is continuously compared to a maximum load value that characterizes a service life of the input/output assembly, and a maintenance message is output when the maximum load value is reached.

A vehicle notification apparatus recognizes an object of driving over on a road on which a host vehicle travels based on a detection result by a front sensor of the host vehicle, determines whether the object of driving over flies backwards based on a detection result by a rear sensor of the host vehicle when the object of driving over is recognized, and notifies a following vehicle of projectile information corresponding to the flight of the object of driving over when it is determined that the object of driving over flies backwards.

One or more devices in an accident detection and recovery computing system may be configured to determine that vehicle accidents have occurred, collect and analyze accident characteristics and other related data, and providing customized accident recovery services. Mobile computing devices, alone or in combination with vehicle-based systems and external devices, may detect accidents or receive accident indication data. After determining that an accident has occurred, mobile computing devices and/or vehicle-based systems may be configured to determine accident characteristics, retrieve vehicle data and vehicle occupant data from one or external servers, determine the damages or potential damages resulting from the accident, and determine one or more accident recovery options or recommendations based on the accident damages. Various user interface screens may be generated and displayed via the user's mobile device and/or a vehicle-based display device to provide the user with accident information, damages, and recovery options or recommendations.

According to one aspect of the present disclosure, a device and technique for impact detection includes a housing enclosing a mass member where the housing is configured to enable movement of the mass member from a first position to a second position within the housing in response to receipt by the housing of an acceleration event. The impact indicator also includes switch circuitry and a passive radio-frequency identification (RFID) module coupled to the switch circuitry. Responsive to movement of the mass member from the first position to the second position, the mass member causes a change in the switch circuitry where the change in the switch circuitry causes a change in a value output by the RFID module when activated.

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.

A test fixture for identifying the sweet spot of a bat suspends the bat in a vertical orientation via a fixed pivot point and limits rotational movement of the bat to a single plane. A pendulum with an impact mass is caused to contact the bat at various locations along the barrel of the bat at a fixed velocity. Rotational movement of the impact mass is limited to the single plane. Peak acceleration is measured proximate to the handle of the bat. The sweet spot is identified based on measured minimum peak acceleration. For example, if there is a single measured minimum peak acceleration then the corresponding contact location at the barrel is the sweet spot. If there are multiple measured minimum peak acceleration instances then a center or average contact location of those instances in identified as the sweet spot.
