Embodiments of the present invention relate to a chaff electronic countermeasure device for protecting mobile platforms against radio frequency threats. A device comprises an antenna that is in communication with a substrate. An integrated circuit is in electrical communication with the antenna. The device is configured to absorb from a source a first radio frequency having a first amplitude. In response to absorbing the first radio frequency, the device reradiates at least a portion of a second radio frequency having a second amplitude toward the radar source, which results in an increased radar cross section of the device as perceived by the radar source. The second amplitude is higher than the first amplitude.

Before a person can use any weapon, such as a gun or a rifle, effectively, the sight must be aligned to the barrel through a zeroing process. An improved zero target is developed which is inexpensive and applicable to many different weapon sight scenarios. By making a universal zero target, users need only a single target eliminating the need for procuring and storing various targets. Additionally, the multi-sight target eliminates the need for field expedient zeroing solutions. The product saves both time and money and improves the results for weapon users.

The invention provides conspicuity devices and methods. A first embodiment includes a glove with at least one elongate lighting device adapted and configured to admit light having an advantageous spectral energy distribution. Additional articles of clothing are provided herein for enhanced conspicuity, such as for emergency workers and athletes.

Systems and methods are provided for provisioning of telecommunications signals in moving trains. Scattering panels may be utilized for redirecting wireless signals, such as by scattering them, to provide better communication performance on the moving trains. The scattering panels may be configured to scatter the signals, such as by reflecting them. The scattering panels may be configured for operation in conjunction with a number of antennas that communicate the signals being scattered via the scattering panels.
