Abstract

Devices, systems, and methods are provided for alerting a pedestrian, such as a visually impaired pedestrian, of a vehicle in the vicinity. In general, signals are transmitted from a vehicle to a device carried by a pedestrian, such as a mobile terminal. In response, the pedestrian'"'"'s device may generate an alarm, such as a vibration or an audible alarm, informing the pedestrian that a vehicle is nearby. In some cases, the pedestrian'"'"'s device may transmit activation signals to the vehicle after receiving the signals from the vehicle. The activation signals may cause speakers on the vehicle to emit an audible alarm, alerting the pedestrian of the presence of the vehicle.

Claims

1. A system comprising:

a first device carried by a vehicle and configured to send signals indicating a presence of the vehicle, further configured to alter an amplitude of the signals to provide an indication of a speed of the vehicle;

a second device carried by a pedestrian and configured to receive the signals from the first device; and

at least one speaker carried by the vehicle in communication with the first device, wherein the second device is configured to transmit activation signals to the first device in response to receiving the signals from the first device, and wherein the first device is configured to instruct the at least one speaker to issue an audible alarm in response to receiving the activation signals from the second device;

wherein the second device is configured to alert the pedestrian regarding the presence of the vehicle in proximity to the pedestrian in response to receiving the signals from the first device, the second device being further configured to allow the pedestrian to select a type of alert received, and wherein the second device is further configured to sound a tone more frequently as the vehicle gets closer to the second device.

2. The system of claim 1, wherein the first device is configured to send the signals in random bursts.

3. The system of claim 1, wherein the first device is configured to send the signals with a signal strength that is associated with the speed of the vehicle.

4. The system of claim 1, wherein the second device is configured to vibrate in response to receiving the signals from the first device.

5. The system of claim 1, wherein the second device comprises a mobile terminal.

6. A device comprising:

a receiver configured to receive signals from a vehicle indicating a presence of the vehicle;

a processor in communication with the receiver configured to provide an alert to a user regarding the presence of the vehicle in proximity to the user in response to receiving the signals, wherein an amplitude of the signals is altered to provide an indication of a speed of the vehicle; and

a transmitter in communication with the processor, wherein the processor is configured to instruct the transmitter to transmit activation signals to the vehicle in response to receiving the signals indicating the presence of the vehicle such that the activation signals cause the vehicle to issue an audible alarm;

wherein the receiver is configured to allow the user to select a type of alert received, and wherein the receiver is further configured to sound a tone more frequently as the vehicle gets closer to the receiver.

7. The device of claim 6 further comprising a vibrating element in communication with the processor, wherein the processor is configured to cause the vibrating element to vibrate in response to receiving the signals from the vehicle.

8. The device of claim 6 further comprising a speaker in communication with the processor, wherein the processor is configured to cause the speaker to issue an audible alarm in response to receiving the signals from the vehicle.

9. The device of claim 6, wherein the device comprises a mobile terminal.

10. A device comprising:

a transmitter configured to transmit signals indicating a presence of a vehicle to a user device in proximity to the vehicle, the transmitter configured to transmit signals with an interval between signals governed at least in part by a random number generator, wherein an amplitude of the signals is altered to provide an indication of a speed of the vehicle;

a receiver configured to receive activation signals from the user device;

at least one speaker configured to issue an audible alarm; and

a processor in communication with the transmitter, the receiver, and the at least one speaker;

wherein the signals transmitted by the transmitter cause the user device to transmit the activation signals, and wherein the processor is configured to instruct the at least one speaker to issue the audible alarm as long as the receiver continues to receive the activation signals and for a predetermined amount of time after the receiver ceases to receive the activation signals.

11. The device of claim 10, wherein the transmitter is configured to transmit the signals in random bursts.

12. The device of claim 10, wherein the transmitter is configured to transmit the signals with a signal strength that is associated with the speed of the vehicle.

13. A method comprising:

receiving an input from a user indicating a desired type of alert;

receiving, using an electronic receiver, signals at a location of a user indicating a presence of a vehicle, wherein signals have an amplitude providing an indication of a speed of the vehicle;

alerting the user regarding the presence of the vehicle in proximity to the user in response to receiving the signals, wherein the user is alerted with the desired type of alert, wherein the alert comprises a tone sounded more frequently as the vehicle gets closer to the electronic receiver; and

ceasing to alert the user after a predetermined amount of time following cessation of the signals.

14. The method of claim 13, wherein receiving the signals comprises receiving the signals from a plurality of vehicles.

15. The method of claim 13, wherein alerting the user comprises producing vibrations at the location of the user.

16. The method of claim 13, wherein alerting the user comprises transmitting activation signals to the vehicle to cause the vehicle to issue an audible alarm.

17. The method of claim 13 further comprising adjusting a strength of the activation signals based on a user input.
