This method for manufacturing a device for locating an impact comprising an interactive surface having a front face for receiving an impact and at least three transducers that need to be distributed and attached against the front face or a rear face of the interactive surface, comprises the following steps: determining a central positioning point for each transducer on the front face or rear face of the interactive surface; attaching each transducer, via the lower conductive layer thereof forming a first electrode, around the central positioning point thereof. It further comprises, following the attachment of each transducer, a step of machining the free upper conductive layer of at least one of the transducers, using a machine tool, at least as far as a piezoelectric intermediate layer of this transducer, in order to form a second electrode of this transducer, centering it around the central positioning point thereof.

An impact indication system for indicating an impact of a projectile on a target. The impact indication system includes an impact sensing system including a g-force sensor, a housing engagable with the target, and a first computing device including at least a processor and a memory. The impact indication system further includes a signal output unit including a housing, a signal output device, a second computing device including a processor and a memory, the first computing device operable to send a signal to the second computing device in response to sensing the impact, and the second computing device operable to produce a signal indicative of the impact.

A hardened inductive device and systems and methods for protecting the inductive device from impact is provided. The inductive device is hardened with protective coating and/or an armor steel housing. The hardened inductive device is protected from impact by an object such as a bullet and leakage of dielectric fluid is prevented. Acoustic and vibration sensors are provided to detect the presence and impact, respectively, of an object in relation to the inductive device housing. The measurements of the acoustic and vibration sensors are compared to thresholds for sending alarms to the network control center and initiating shut-down and other sequences to protect the active part. The acoustic sensor results are utilized to determine the location of origin of the projectile.

A system for sensing the impact of a bullet on a target and remotely reporting the successful impact to the shooter by means of a signal transmitted from a sensor transmitter to a receiver incorporated with headphones, ear buds or an Smart phone, tablet or other device with WIFI and/or Blue tooth capability. The sensor includes a wireless transmitter and a impact/vibration sensor such as a piezoelectric sensor. The target impact sensors can be used with various stationary targets such as metallic, plastic, film, or paper targets, but can also be used on movable targets such as body armor or removable patches worn by players in mock warfare or games such as paint ball competition to effect audible signals.
