Abstract:
An apparatus (100) includes a canine harness (101) with a radio frequency inhibitor (400). A leash (1002) can serve as a control device (102). The leash can selectively mechanically couple to the canine harness and electrically couple an actuator (114) to the radio frequency inhibitor. When the actuator is actuated, the radio frequency inhibitor is to emit one or more radio frequency inhibition signals (405), which can include the emission of all programmed signals simultaneously. Radio frequency inhibitors can also be integrated into clothing or armor (1802), as well as equipment (1901). The radio frequency inhibitor can interrupt, suppress, or halt electronic detonation communications to an explosive device.
Abstract:
A media playback device has programmable signal processing capabilities and an input receiving signals representative of ambient noise. The media playback device identifies an output response characteristic and an attenuation characteristic of a set of headphones associated with the media playback device, predicts a property of audio output by the headphones at a user's ear based on the ambient noise input signal, the output response characteristic, and the attenuation characteristic of the headphones, predicts expected residual ambient noise at the user's ear, when wearing the headphones, derived from the ambient noise input signal and the attenuation characteristic, and modifies masking audio signals to be provided to the headphones such that they will mask the expected residual ambient noise at the user's ear.
Abstract:
Methods and apparatuses for addressing open space noise are disclosed. In one example, a method for masking open space noise includes outputting a test signal from a speaker, the test signal operable to measure a speech transmission quality of a transmission channel. The method includes receiving the test signal at a microphone, outputting a detected test signal, and processing the detected test signal to determine the speech transmission quality of the transmission channel. The method further includes adjusting an output level of a noise masking signal from the speaker responsive to the speech transmission quality.

In various areas of application, it is desirable to have a jamming apparatus for jamming radio signals which has a high level of geographical limitation and ensures safe jamming of the radio signals. The present application solves this problem by providing a jamming apparatus which comprises the following: at least one detection device for detecting a target signal which is being sent to at least one communication device; at least one jamming device for jamming the target signal using a jamming signal; a control device which is communicatively connected to the jamming device for the purpose of controlling it; wherein the control device controls the at least one jamming device by receiving at least one input signal for determining a transmission power for the jamming device and/or for a communication device. A central concept of the present invention is thus dynamic regulation of the jamming signal. It is therefore possible to ensure efficient jamming of the appliance which is sending the target signal.
