A synchronized infrared beacon/infrared detector system. The system may include (A) an infrared beacon module configured to generate a time-varying encoded infrared signal, (B) an infrared detector module configured to capture the encoded infrared signal generated by the beacon module, (C) a synchronizer configured to generate a synchronization signal that controls timing of the beacon module and the detector module, and (D) a processor, in communication with the detector module, configured to analyze the infrared signal captured by the detector module. The infrared signal may be modulated at frequencies undetectable by human vision. The synchronizer signal may be produced independent of the capture of, and without input from, the infrared signal.

A laser targeting apparatus rests on a surface and moves, such as by vibrating, wobbling, or shaking, when struck by laser light of sufficient intensity. The apparatus is designed not to fall over, so a user does not have to move to the apparatus and pick it up after a strike. The apparatus has a body that includes a structure, which is preferably one or more printed circuit boards including light sensors, for detecting strikes of laser light, and a motor. When a strike of laser light is detected, power is provided to the motor, which vibrates and causes the apparatus to move.

A method for determining an impact location of an object on a vehicle including reading in a first sensor signal value of a first sensor of the vehicle at a predefined first point in time, a second sensor signal value of the first sensor at a predefined second point in time following the first point in time, and a sample value of a second sensor of the vehicle at a third point in time following the second point in time. Additionally, an interpolation point is calculated from the first sensor signal value and the second sensor signal value by using the sample value, at least one component of the interpolation point corresponding to the sample value. A time lag between an interpolation instant assigned to the interpolation point, and the third point in time takes place. Finally, the time lag is used for determining the impact location of the object.

A shooting system including a target, a gun, and a data processing device is provided. The target includes two or more infrared LEDs, the gun has image capturing means for capturing an image of the target via a visible light cutoff filter provided in its gun barrel while including a switch which operates in conjunction with movement of a trigger and transmission control means for transmitting image data acquired by the image capturing means when this switch operates, and the data processing device includes receiving means for receiving the image data sent from the transmission control means in the gun, calculation means for detecting a light spot position of each of the infrared LEDs from the image data and calculating a distance from the gun to the target and a bullet landing position on the target based on the light spot position, and display means for displaying a result of the calculation.
