DETAILED DESCRIPTION

[0030] When a garage or parking lot is constructed for a residential or commercial building, they usually have a gate to give a permission to the eligible vehicle to enter. For example, when a driver enter the right numbers on the parking keypad or when the driver click on the garage remote, it gives them a permission to enter into the garage or parking lot. All the commercial or residential garage or parking lot have a height limitation whereby a vehicle with a particular height can be parked and does not allow vehicles with a height above those permissible limits. It is important to indicate a garage height limit because some large vehicle of a resident or a guest may have more height than the required and the driver of that vehicle is not aware of their vehicles' height. Further, as entering into the garage or parking lot, drivers are usually in hurry, they click on the remote or keypad and decided to enter without noticing the height sign, damaging their vehicles' ceiling and the garage/parking lot ceiling as well.

[0031] The usual way to deal with the vehicle height when entering the garage or parking lot depend mainly on a sign, or a horizontal bar, hanged from the ceiling to guide the vehicle as to the permissible height within that area. However, as mentioned the driver might not be aware of the actual height of his vehicle and decided to go forward and that lead to damages requiring repairs and thus cost.

[0032] The presented invention deals with the problem and provides a vehicle height clearance sensor system that can be installed and connected to a regular garage entrance door or a parking lot entrance door which do have height restrictions.

[0033] FIG. 1 shows details of the disclosed vehicle height clearance sensor system. As shown, the system comprises: a photo-sensor bar 101, an infrared emission bar 102, an alarming light bar 109 with an alarming light 110, an electronic display 112 and a garage or parking entrance gate 113.

The system comprises two alarming light bars 109. The alarming light bar is installed at a distance or approximately 0.5 meter away from the garage or the parking lot entrance gate. The distance 114 may be more or less than the indicated and will depend on manufacturer or owner choice. The alarming light bars are present on both sides or one side of the entrance 111 of the garage or parking lot. The alarming light 110 gets activated if and when a vehicle with above the permissible height passes through the system such that it gives an indication to the driver to stop. The system further comprises of an electronic sign 112 present on top of the garage or parking lot entrance gate 113. The electronic sign may be present on a desired location such as the left side or the right side of the garage or parking lot entrance gate.

[0035] FIG. 2 shows a top view of the disclosed vehicle height clearance sensor system showing distance between the infrared emission bar 102 and the photo-sensor bar 101 is approximately 2.5 meter. However, distance can be more or less depending on the number of entrances to be covered e.g if there are more than one entrance gate to the garage or parking lot, infrared and photo-sensor bar can each be fixed onto one side of the garage/parking lot covering both the entrance. Also, distance may depend on the size of the vehicles such as vehicle is a car, truck, RV or others. Also, distance between the infrared bar and the alarming bar or distance between the photo-sensor bar and the alarming bar can vary depending on all the factors as stated above and also on the owner's or manufacturer's choice.

[0036] FIG. 3 shows structural details of an infrared emission compartment 301. As discussed above there is an upper infrared emission compartment 105 and lower infrared emission compartment 106. The position of upper infrared emission compartment is fixed such that it indicated the highest position for the vehicle or the permissible height. The lower infrared emission compartment is at least 0.5 meter away from the ground level.

[0037] The infrared emission compartment comprises a cylindrical body 302. The cylindrical shape is open from one side and comprise of more than one wing 304, which forms an opening. There is a hole 305 present onto the wings of the infrared emission compartment, wherein a screw 306 can pass through the hole and with the screw nut 307 can help fix the infrared emission compartment at a desirable height onto the infrared emission bar. The infrared emission compartment further comprise of an infrared piece 303 that emits an infrared signal towards the photo-sensor bar 101, wherein the photo-sensor bar is present on the same line of axis as of the infrared emission bar 102. The infrared emission compartment may be of other shape such as a rectangle, square as referenced to the shape of the infrared emission bar. The infrared emission compartment can further be adjusted, moved up or down and fixed onto the infrared emission bar.

[0038] FIG. 4 shows structural details of an photo-sensor compartment 401. The photo-sensor compartment as attached to the photo-sensor bar 101 is a hollow cylindrical metallic body 402. The cylindrical shape is open from one side and comprise of more than one wing 403, which forms an opening. There is a hole 407 present onto the wings of the photo-sensor compartment, wherein a screw 404 can pass through the hole 407 and with the screw nut 405 can help fix the photo-sensor compartment at a desirable height onto the photo-sensor bar. The photo-sensor compartment further comprise of a photo-sensor piece 406. The photo-sensor piece and the infrared piece are position in such a way that they face each other and forms an invisible line, invisible to naked eye, when the system is in ON position. The photo-sensor compartment may be of other shape such as a rectangle, square as referenced to the shape of the photo-sensor bar. The photo-sensor compartment can further be adjusted, moved up or down and fixed onto the photo-sensor bar.

[0039] As discussed above there is an upper photo-sensor compartment 103 and lower photo-sensor compartment 104. The position of upper photo-sensor compartment is fixed such that it indicated the highest position for the vehicle or the permissible height. The lower photo-sensor compartment is at least 0.5 meter away from the ground level.

[0040] FIG. 5A shows a use of the disclosed system 501 as a vehicle 502 passes through the system. As shown, the system is showing to emit the upper infrared line 107 and the lower infrared line 108 from the infrared compartments. As the vehicle passes through the entrance 111 and thus through the system, it will cross the infrared lines. If the vehicle crosses only the lower infrared line 108, the vehicle is within the permissible height and thus the vehicle will pass through the garage or parking entrance gate. Further, as shown in FIG. 5B, if the vehicle crosses both the upper infrared line 107 and the lower infrared line 108, this gives an indication that the vehicle is above the permissible height and thus is not allowed to or should not enter the garage/parking gate 503. In such an event, as the vehicle crosses the upper infrared line, a chain of events or an event will occur giving indication to the driver or other that the vehicle is above the permissible height allowed to enter the garage/parking lot. The events that may occur is activation of one or more than one alarming lights 110 present on the alarming light bar 109. The alarming light is present in a visible range of the driver. Further, the garage entrance gate 113 will start to close automatically, even if it started to open after receiving a signal from a garage remote as operated by a driver or another user or entrance gate will not open even after the user gives signal through a garage/parking opener or entering keys on a keypad. A third event that may occur is that a message will be displayed onto the electronic sign 112 for driver to read that the vehicle is above the permissible height. The events can happen in a series such as crossing of both the infrared lines; activation of alarming lights; closing of the garage/parking gate, if it was signaled to open and displaying of a warning message on electronic sign board present in the visible and readable distance. Thus, the activation of alarming lights, closing of the garage/parking gate, and displaying of a warning message on electronic sign board can happen one after another as soon as the vehicle crosses both the infrared lines. The series can be changed or there can be just one event happening following crossing of both the lines such as closing or not opening of the garage or parking lot entrance gate; activation of the alarming light giving signal to stop the vehicle and display onto the electronic sign giving indicators to the driver that the vehicle is above the permissible height.

[0041] FIG. 6 shows a step-by-step functioning of the disclosed system with a vehicle of a permissible height. The functioning as disclosed comprises: switching ON the vehicle height clearance system, such that an infrared signal is emitted each from an upper infrared emission compartment and a lower infrared emission compartment, wherein the infrared emission compartment is present on an infrared emission bar 601; forming of two infrared lines, wherein the lines are formed when the infrared signal from the infrared emission compartment falls onto a photo-sensor compartment present on a photo-sensor bar 602; passing of a vehicle through the system to enter into the garage or parking lot entrance gate, wherein as the vehicle passes the system, vehicle will cross the two infrared lines 603; moving of the vehicle into the garage or parking lot such that the vehicle crossed only a single infrared line indicating that the vehicle has a permissible height 604.

[0042] FIG. 7 shows a step-by-step functioning of the disclosed system with a vehicle above a permissible height. The functioning as disclosed comprises: switching ON the vehicle height clearance system, such that an infrared signal is emitted each from an upper infrared emission compartment and a lower infrared emission compartment, wherein the infrared emission compartment is present on an infrared emission bar 701; forming of two invisible lines, wherein the lines are formed when the infrared signal from the infrared emission compartment falls onto a photo-sensor compartment present on a photo-sensor bar 702; passing of a vehicle through the system to enter into the garage or parking lot entrance gate, wherein as the vehicle passes the system, vehicle will cross the two infrared lines 703; activation of an alarming light, wherein the activation indicates that the vehicle crossed both the infrared lines 704; moving of the vehicle into the garage or parking lot such that the vehicle crossed both the infrared lines indicating that the vehicle does not have a permissible height and cannot pass through the garage or parking lot entrance gate 705.

[0043] This is total electronic system, that does not require human intervention. The system depend on photo-sensors and infrared to detect the vehicle upper height. It prevent the vehicle from the entering the garage or parking automatically by closing the garage gate and giving the driver a warning and electronic explanation. Using two infrared lines help to differentiate in fraction of seconds between a vehicle with acceptable and unacceptable height.
