Abstract

A real-time surveillance system for aiding vehicle drivers and portable first unit for use therein is provided. The unit includes an image sensor that generates a sequence of images from received light. The system further includes a support to detachably support the unit on the vehicle so that the sensor is capable of receiving light from obstacles, hazards or individuals located in a blind spot region of the vehicle. A display is supported on the vehicle so that the images are viewable by a driver of the vehicle in real time. The system further includes a mechanism to authenticate a person desirous of using the system or removing the unit from the vehicle as an authorized person based, at least in part, on an authenticator. The authenticator includes at least one of a password, a passphrase, a personal identification number, a security token, a security card, and a biometric identifier.

Claims

1. A real-time surveillance system for aiding vehicle drivers, the system comprising:

a portable first unit including;

an image sensor that generates a sequence of images from received light;

a first controller; and

a transmitter controlled by the first controller to modulate a first carrier signal with the images and to transmit the modulated first carrier signal over a wireless communication channel;

a support to detachably support the first unit on the vehicle so that the image sensor is capable of receiving light from obstacles, hazards or individuals located in a blind spot region of the vehicle;

a second unit including;

a second controller;

a receiver to receive and demodulate the first carrier signal to obtain the images; and

a display controlled by the second controller to display the images, the display being supported on the vehicle so that the images are viewable by a driver of the vehicle in real time; and

means for authenticating a person desirous of using the system or removing the first unit from the vehicle as an authorized person based, at least in part, on an authenticator, wherein the authenticator includes at least one of a password, a passphrase, a personal identification number, a security token, a security card, and a biometric identifier.

2. The system as claimed in claim 1, wherein the biometric identifier includes at least one of a fingerprint, a retinal pattern, an infrared vein pattern, a signature, a voice, a face, a bio-electric signal, and a DNA sequence.

3. The system as claimed in claim 1, wherein the transmitter forms a part of the transceiver, a receiver part of the transceiver being controlled by the first controller to demodulate a plurality of satellite carrier signals to obtain satellite position and time data, and to process the position and time data to obtain geographic position data which represents position of the first unit, the transceiver being controlled by the first controller to modulate a second carrier signal with the geographic position data and to transmit the modulated second carrier signal over a wireless communication channel when a person removing the first unit is unauthorized to remove the first unit.

4. The system as claimed in claim 1, wherein the support detachably supports the first unit to a rear of the vehicle.

5. The system as claimed in claim 4, wherein the first unit includes means for electrically connecting the first unit with a wiring harness of the vehicle at the rear of the vehicle.

6. The system as claimed in claim 5, wherein the first unit includes at least one battery to allow operation of the first unit after electrically disconnecting the first unit from the wiring harness.

7. The system as claimed in claim 1, wherein the first unit includes at least one warning device selected from the group consisting of a proximity radar device, a Doppler radar device, a sonar device, an ultrasound device, an ultraviolet sensor, an infrared sensor, and a microwave sensor.

8. The system as claimed in claim 1, wherein the transmitter is controlled by the first controller to modulate the first carrier signal with a set of identification data, the set of identification data uniquely identifying the first unit, and wherein the receiver demodulates the carrier signal to obtain the set of identification data, the second controller determining whether the carrier signal was transmitted by the first unit based on the set of identification data.

9. The system as claimed in claim 1, wherein the image sensor is a video camera.

10. The system as claimed in claim 1, wherein the first controller is a microprocessor-based controller programmed to process the sequence of images to detect when the first unit is moving.

11. A real-time surveillance system for aiding drivers of vehicles having a cab and a trailer releasably connected to the cab, the system comprising:

a portable first unit including;

an image sensor that generates a sequence of images from received light;

a first controller; and

a transmitter controlled by the first controller to modulate a first carrier signal with the images and to transmit the modulated first carrier signal over a wireless communication channel;

a support to detachably support the first unit at the rear of the trailer so that the image sensor is capable of receiving light from obstacles, hazards or individuals located in a blind spot region behind the vehicle;

a second unit including;

a second controller;

a receiver to receive and demodulate the first carrier signal to obtain the images; and

a display controlled by the second controller to display the images, the display being supported on the cab so that the images are viewable by a driver of the vehicle in real time; and

means for authenticating a person desirous of using the system or removing the first unit from the vehicle as an authorized person based, at least in part, on an authenticator, wherein the authenticator includes at least one of a password, a passphrase, a personal identification number, a security token, a security card, and a biometric identifier.

12. The system as claimed in claim 11, wherein the biometric identifier includes at least one of a fingerprint, a retinal pattern, an infrared vein pattern, a signature, a voice, a face, a bio-electric signal, and a DNA sequence.

13. The system as claimed in claim 11, wherein the transmitter forms a part of transceiver, a receiver part of the transceiver being controlled by the first controller to demodulate a plurality of satellite carrier signals to obtain satellite position and time data, and to process the position and time data to obtain geographic position data which represents position of the first unit, the transceiver being controlled by the first controller to modulate a second carrier signal with the geographic position data and to transmit the modulated second carrier signal over a wireless communication channel when a person removing the first unit is unauthorized to remove the first unit.

14. The system as claimed in claim 11, wherein the first unit includes means for electrically connecting the first unit with a wiring harness of the trailer at the rear of the trailer.

15. The system as claimed in claim 14, wherein the first unit includes at least one battery to allow operation of the first unit after electrically disconnecting the first unit from the wiring harness.

16. The system as claimed in claim 11, wherein the first unit includes at least one warning device selected from the group consisting of a proximity radar device, a Doppler radar device, a sonar device, an ultrasound device, an ultraviolet sensor, an infrared sensor, and a microwave sensor.

17. The system as claimed in claim 11, wherein the transmitter is controlled by the first controller to modulate the first carrier signal with a set of identification data, the set of identification data uniquely identifying the first unit, and wherein the receiver demodulates the carrier signal to obtain the set of identification data, the second controller determining whether the carrier signal was transmitted by the first unit based on the set of identification data.

18. The system as claimed in claim 11, wherein the image sensor is a video camera.

19. The system as claimed in claim 11, wherein the first controller is a microprocessor-based controller programmed to process the sequence of images to detect when the first unit is moving.
