Method and device for detecting presence of vehicle in parking space
First Claim
1. A method for notifying at least one user of the status of a plurality of parking spaces, comprising:
- transmitting at least one pulse from each of a plurality of transceivers, wherein each of said plurality of transceivers is located on an opposing side of a device housing and angled at a trajectory towards one of a plurality of parking spaces, and for each pulse;
receiving by respective transceiver a corresponding echo created by said pulse being reflecting back from at least one object occupying respective 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 respective said parking space;
using said occupancy of respective said parking space to determine the status of respective said parking space by at least one processing unit, together with information on time of day and parking space permission; and
notifying at least one user of respective said parking space status by visual indication from a plurality of respective light emitting diode arrays.

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.

11. A device for monitoring and notifying at least one user of the status of a plurality of parking spaces, comprising:
-
a plurality of transceivers each transmitting at least one pulse and receiving at least one echo from respective said pulse that has reflected off an object occupying one of said plurality of parking spaces; at least one processing unit configured for measuring time between each said pulse and each said corresponding echo for determining statuses of said associated plurality of parking spaces; 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 statuses of said plurality of parking spaces; at least one power source for supplying power to said plurality of transceivers, said at least one processing unit, and said at least one light emitting diode array; and a housing for containing said plurality of transceivers, 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, wherein each of said plurality of transceivers is located on opposing sides of said housing and angled at a trajectory towards one of said associated plurality of parking spaces. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
