Abstract: Systems and methods are method of for remote monitoring of an area with a remote sensing device (100, 200, 300) encased in a rubber ball (302). A remote sensing device (100, 200, 300) is provided which receives a spoken description of a location of the remote sensing device and stores the spoken description as predetermined location information. The description can be received directly prior to deployment or wirelessly transmitted from another device (400). The remote sensing device can sense information related to its environment via a motion sensor (314), such as whether an intruder is located within a vicinity of the remote sensing device (100, 200, 300). The remote sensing device (100, 200, 300) can then transmit the predetermined location information and the environment information to the another device (400) in response to the sensing. In response to receipt, the other device (400) can render the predetermined location information and the environment information in an audible format.

Abstract: Boomless-microphones are described for a wireless helmet communicator with siren signal detection and classification capabilities. An acoustic component receives an audio signal and comprises a left acoustic sensor and a right acoustic sensor. The left acoustic sensor is mountable or attachable to the surface of a left wall of a helmet and the right acoustic sensor is mountable or attachable to the surface of a right wall. A speaker component can generate an echoless audio signal via signal inversion of the audio signal, outputs to a left speaker mountable or attachable to a left ear area of the helmet and a right speaker mountable or attachable to a right ear area of the helmet. A signal enhancement component can increase an intensity of the first audio signal associated with an emergency siren based on a determined proximity of an emitting emergency vehicle or emergency object to the device.

Abstract: Systems and methods are presented for detecting a direction of an incoming projectile and determining a source location of the projectile. One or more resonant sensors (comprising a plate, piezo electric sensor, etc.) can be arranged, where shockwaves from the projectile (e.g., shockwaves from a bullet travelling at supersonic speeds) are incident upon the plate and cause the plate to resonate. The resonance causes an electrical signal to be generated by the piezo electric sensor (e.g., a piezo electric film sensor), the greater the degree of resonance in the plate, the higher the magnitude of signal generated by the piezo electric sensor. By comparing the magnitude of the piezo electric signals across the array of resonant sensors it is possible to determine a trajectory of the projectile and hence a location of the source of the projectile. Acoustic waves can also be generated by muzzle waves.
