Abstract: A method of communicating between a person within a target vehicle and a law-enforcement person includes establishing a connection between a law-enforcement transceiver and a target vehicle transceiver using a protocol and encoding an audio signal into an encoded audio signal by the law-enforcement transceiver using the protocol, The encoded audio signal is transmitted from the law-enforcement transceiver and received by the target vehicle transceiver where the encoded audio signal is accepted by the target vehicle transceiver through a feature in the protocol, the feature in the protocol allowing limited access to an audio transducer of the target vehicle, the encoded audio signal is decoded back into the audio signal by the target vehicle transducer and the audio signal is reproduced on the audio transducer within the target vehicle.

Abstract: A system for communicating emergency information to one or more user devices includes a computer for communicating to the one or more user devices (e.g. smartphones). When a situation is encountered (e.g. a shooter, a person with a knife, a fire), the computer communicates with the user devices local to the situation to place them in a secure mode, dimming their displays, quieting the user devices, providing efficient communication tools, and presenting update information regarding the situation such as location of an invader or fire, escape routes. Further, after entering secure mode, audio is captured from the device and used by the computer to determine a location of a gunshot.

Abstract: A vehicle communication system for communicating with a person who is within a vehicle includes a device for hearing audible noises that emanate within the vehicle at locations external to the vehicle without making physical contact with the vehicle. Communication from the person in the vehicle to a person external to the vehicle is performed by aiming a light beam from the vehicle and receiving reflections of the light beam. The light beam is modulated by vibration of the vehicle caused the audible noises from within the vehicle. The received light beam is then processed to reproduce the audible noises so that the audible noises can be heard from a location outside of the vehicle, even when the vehicle is sealed (windows closed, etc.).

Abstract: An application for a two-way communication system for communicating with a person who is within a second vehicle includes a short-range radio transmitter within a first vehicle to transmit audio to a radio within the second vehicle. Communication from the person in the second vehicle to a person in the first vehicle is performed by aiming a light beam from the first vehicle at the second vehicle and receiving reflections of the light beam at the first vehicle. The light beam is modulated by vibration of the second vehicle caused by the person speaking in the second vehicle. The received light beam is then processed to reproduce the sound of the person's voice.

Abstract: An application for a two-way communication system for communicating with a person who is within a vehicle includes a short-range radio transmission to transmit audio to a radio within the vehicle. Communication from the person is done by reflecting a light beam on a window of the vehicle and receiving the light beam. The light beam is modulated by vibration of the window caused by the person's voice. The received light beam is then processed to reproduce the sound of the person's voice.
