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.

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 device for locating an impact against an interactive surface comprises M transducers distributed against the interactive surface, M4, and an electronic central unit programmed to locate the impact by analysing time differences of propagation of progressive mechanical waves from the impact to the transducers on the basis of instants of impact detection identified in the electrical signals supplied by the transducers. The electronic central unit is programmed to select, among the M transducers, a subset of N transducers, 3N<M, of which the electrical signals chronologically comprise the first N instants of detection of impact identified and to locate the impact based on these N first instants of detection of impact identified and on the places of arrangement in the interactive surface of the N transducers selected.

In one embodiment, a sensor network is attached to a structure and employed to detect and analyze load changes such as impacts from projectiles. An analyzer coupled to the sensors can determine where on the structure the projectile impacted. Coupled with information on the origin point of the projectile, i.e. where it was fired from, the analyzer can then estimate the trajectory of the projectile. The analyzer can also determine whether the projectile passed through the structure and, if so, can extrapolate the estimated trajectory to determine an estimation of whether the projectile has also impacted an object behind the structure.

The present invention provides systems and methods for electronic targeting, and hit or touch detection of projectiles or objects, such as from some type of gun, bow (archery), ball, human touch, animal touch. Targets/nodes have hit/touch/contact detection implements and are in radio communication with a gateway, which may be standalone or integrated into a master target. The gateway is in radio communication with an app on a smart device and also includes the capability for data connectivity to the cloud. Electronic gaming and other touch event activities remote activities of geographically disparate groups of targeting-type or hit/touch/contact detection implements are provided.

This apparatus offers multiple training scenarios which designates the targets to be hit and evaluates response. The apparatus assists in the evaluation and training of a shooter using multiple scenarios, detection of target strikes, timing, accuracy, and threat assessment. The system may be used with unmodified weapons and may not require attachments to weapon or shooter. The light source(s) in this apparatus may include visible lasers, focused light emitters, video or image projectors. The shooter may use live ammunition, and the weapon may be fired and operated independently of the control system. Hit detection on the targets may use vibration, accelerometer, acoustic, optical or thermal sensors that respond to projectile strikes on the designated target(s). If the specific location of the strike on the target is desired, nested targets and multiple sensor triangulation calculations may be used. This system designates which targets to shoot, when to fire, and evaluates the results.
