Abstract

A method for notifying a user of the status of a parking space. The method comprises transmitting a pulse from a transceiver assigned to a parking space and for each pulse receiving by transceiver a corresponding echo created by said pulse being reflecting back from a object occupying said parking space. The method further comprises measuring corresponding echo time by a processing unit. The method further comprises comparing said corresponding echo time to a predefined range of echo times by a processing unit to determine occupancy of said parking space. The method further comprises using said occupancy of parking space to determine the parking space status by a processing unit, together with information on time of day and parking space permission. The method further comprises notifying a user of said parking space status by visual indication from at least one light emitting diode array.

Claims

1. A method for notifying at least one user of the status of at least one parking space, comprising:

transmitting at least one pulse from at least one transceiver assigned to a parking space and for each pulse;

receiving by transceiver a corresponding echo created by said pulse being reflecting back from at least one object occupying said parking space;

measuring corresponding echo time by at least one processing unit;

comparing said corresponding echo time to a predefined range of echo times by at least one processing unit to determine occupancy of said parking space;

using said occupancy of parking space to determine the status of said parking space by at least one processing unit, together with information on time of day and parking space permission;

notifying at least one user of said parking space status by visual indication from at least one light emitting diode array.

2. The method of claim 1, wherein said user is a driver of a motor vehicle looking for a parking space, and said driver uses the visual notification to find a parking space for the vehicle.

3. The method of claim 1, wherein said notification of parking space status is further transferred to at least one internet server together with information on geographic location of said parking space.

4. The method of claim 3, wherein said user is a driver of a motor vehicle looking for a parking space, said driver parks their motor vehicle in said parking space, and said internet server notifies said driver when said vehicle has been moved.

5. The method of claim 3, wherein said user is a parking space manager and said internet server transfers to said parking manager a plurality of parking space status notifications, both current and historical, which are used to plan future parking resources.

6. The method of claim 3, wherein said user is parking enforcement officer, and said internet server transfers said parking space notification which is of a status that corresponds to a parking violation.

7. The method of claim 1, wherein said at least one transceiver is an ultrasound transceiver and said at least one pulse is an ultrasound pulse.

8. The method of claim 1, wherein said transceiver is a multiple sensor transceiver assigned to a plurality of parking spaces and said processing unit produces a plurality of associated parking space statuses.

9. The method of claim 1, wherein said echo time is further processed by said at least one processing unit to convert echo time to distance to said parked vehicle and said predefined range is measured by distance units allowing more convenient installation.

10. A device for monitoring and notifying at least one user of the status of at least one parking space, comprising:

at least one transceiver which transmits at least one pulse and receives at least one echo from said pulse that has reflected off an object occupying said at least one parking space;

at least one processing unit configured for measuring time between said pulse and said corresponding echo for determining status of said associated at least one parking space;

at least one light emitting diode array capable of at least one visual notification through the use of emitted light colors, light flashing rates, and light flashing patterns for notifying said at least one user of status of said at least one parking space;

at least one power source for supplying power to said at least one transceiver, said at least one processing unit, and said at least one light emitting diode array; and

a housing for containing said at least one transceiver, said at least one processing unit, said at least one power source and said at least one light emitting diode array wherein said housing is specifically designed to provide protection of internal components against adverse effects of the environment and against adverse effects of vertical and sheer stresses from motor vehicles rolling over housing.

11. The device of claim 10, wherein said device further comprises an RF electronics transceiver to send said at least one parking space status to and receive instructions from at least one internet server, relayed through at least one routing controller.

12. The device of claim 10, wherein said at least one power source is at least one alkaline battery contained within said housing to provide power to said at least one transceiver, said at least one processing unit, and said at least one notification unit.

13. The device of claim 11, wherein said at least one power source is at least one rechargeable battery contained within said housing to provide power to said at least one transceiver, said at least one processing unit, and said at least one notification unit.

14. The device of claim 10, further comprising at least one photovoltaic cell for recharging said at least rechargeable battery contained within said housing to provide power to said at least one transceiver, said at least one processing unit, and said at least one notification unit.

15. The device of claim 10, wherein said at least one power source is at least one alternating current power supply external to said housing to provide power to said at least one transceiver, said at least one processing unit, and said at least one notification unit.

16. The device of claim 10, wherein said at least one transceiver is at least one ultrasound transceiver.

17. The device of claim 10, wherein said at least one transceiver comprises a separate at least one emitter and separate at least one receiver.

18. The device of claim 10, wherein said at least one transceiver is a plurality of transceivers for monitoring a plurality of corresponding said parking spaces.

19. The device of claim 10, wherein said housing contains structural elements designed to withstand rollover pressures from vehicles.

20. The device of claim 10, wherein said housing includes an integrated o-ring seal between top and bottom halves of said housing to offer protection from adverse effects due to the environment, including dust, humidity, water and the like.

21. The device of claim 10, wherein said device is located adjacent to the parking space.

22. The device of claim 10, wherein said device is located up to 4 meters from the parking space.

23. The device of claim 10, wherein said housing contains at least one recess in said housing for protection of at least one corresponding said transceiver.
