US 2014/0112101 A1 · METHOD AND DEVICE FOR DETECTING PRESENCE OF VEHICLE IN PARKING SPACE

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.

Dependent claims

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.

3 more elements

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.
