Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Technical Field  
         [0002]     This application relates to vehicle security, with regards especially to both the prevention of false alarms and decreased response time to actual alarms. More specifically, the application relates to the combined use of on-board cameras and cellular telephones to allow the owner of a vehicle to (a) be alerted when an alarm is triggered, (b) view the vehicle interior. and/or immediate area, and (c) respond by either turning off the alarm or calling the police.  
         [0003]     2. Description of Related Art  
         [0004]     Vehicle theft is widespread and can cause the loss of a sizeable investment to a user. The most common type of vehicle protection system uses an alarm that goes off when a thief attempts to open the vehicle. Unfortunately, these alarms can often be triggered unintentionally, such as when a person or another vehicle bumps the armed vehicle. Even strong vibrations, such as from a nearby clap of thunder during a storm, or a 21-gun salute during the funeral of an ex-President, can set off a false alarm.  
         [0005]     Many additional types of vehicle alarms have been suggested. For example, U.S. Pat. No. 5,081,667 to Drori et al. discloses integrating a cellular phone installed in a vehicle with the vehicle security system, such that after integration, the user can start or monitor the engine from any phone, can program in a phone number at which the user can be reached in case of intrusion into the vehicle, or can initiate listening or two-way conversations with the intruder.  
         [0006]     U.S. patent application 2002/0096132 to Parker Jr. et al. discloses an embedded pager or cell phone carried as part of a vehicle security system. In one embodiment, an intrusion causes a camera on the dashboard of the vehicle to take a picture of the driver, which can then be forwarded to the user&#39;s cell phone.  
         [0007]     U.S. Pat. No. 5,027,104 to Reid utilizes a number of hidden cameras in various positions around a vehicle. The security device can send an alarm to the owner, using a given frequency, when an intrusion is detected, and one embodiment can then send a video signal from the cameras to a hand-held monitor in the user&#39;s possession.  
         [0008]     While these inventions are aimed at apprehending an auto thief, they do not take into consideration the nuisance factor of false alarms, nor do they enable a response to such a false alarm. Therefore, it would be desirable to have an easy means for a user to be notified when their car alarm goes off and to not only be able to distinguish between a theft-in-progress and a false alarm, but to be able to turn off the alarm remotely for a false alarm.  
       SUMMARY OF THE INVENTION  
       [0009]     The present invention provides a device and method by which a user can be alerted to a detected condition regarding their vehicle, can view what is happening in and around the vehicle, and can remotely turn off or reset an alarm if it is determined that the alarm is false. Additionally, provision is made for contacting the police or other authorities if a theft is actually in progress. All this is provided using any cellular telephone, a device that is fast becoming ubiquitous in much of the world.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0000]     Equipment  
         [0016]     With reference to the figures, an embodiment of the invention will be discussed.  FIG. 1  discloses an automobile that can be equipped with a security system according to an embodiment of the invention. In this embodiment, the security system is preferably factory installed while the vehicle is being built, although it can also be installed as an aftermarket security system.  
         [0017]     The components of the innovative alarm system are shown diagrammatically in  FIG. 2 . This system  200  comprises sensors  210  to detect an intrusion, a local alarm  202 , one or more cameras  212 , a processor  204 , memory  208 , and cellular phone circuitry  206 . Preferably, as many as possible of these components are placed in locations that are difficult for a thief to reach and disconnect, such as under the hood of the vehicle. The cameras  212  are placed so that they can be used to view the interior and immediately adjacent exterior of the vehicle. As recent technology has made substantial progress in the miniaturization of cameras, there are many possible locations for the placement of cameras. At least one camera  212  is preferably placed so that it can view the driver&#39;s seat and at least a portion of the window on the driver&#39;s side of the vehicle, since these are the locations where one is most likely to see an intruder. Other cameras  212  can be placed to afford a view out any of the windows or to provide other views of the interior of the vehicle. These are preferably digital cameras, although they can take either still shots or videos. The camera installations can be fixed, or they can have some degree of rotation, so that they can pan across the field of view. Alternatively the cameras can contain a wide-angle lens to enable a view of a larger field.  
         [0018]     The sensors  210  used to detect intrusion can be any type of sensor. Most commonly, these would be motion detectors or sensors for a door opening while the alarm is set, but the sensors can include any type, such as glass break, attempted opening of the hood, etc. A processor  204 , connected to a memory  208 , is also connected to receive input from the sensors  210  and to control the alarm  202 , the cameras  212 , and the cellular phone circuitry  206 .  
         [0019]     In additional to the cellular phone circuitry  206  in the vehicle  100 , the user can utilize their own mobile phone to program the system and to be contacted by the system when the alarm is triggered. Preferably, the user&#39;s mobile phone is small enough that it can be carried in a pocket and contains a screen large enough for viewing pictures from the cameras placed within the vehicle.  FIG. 3  demonstrates an exemplary mobile telephone for use with the inventive system, according to one embodiment of the invention. This figure demonstrates a model  610  available from Sony Ericsson. This mobile phone  300  will fit into a pocket, yet almost half of its front surface is a screen  302  capable of viewing pictures. Additionally, there is a standard numeric keypad  304 , a joystick  306 , and four buttons placed around the joystick.  
         [0000]     Operation  
         [0020]     Because the innovative system uses cellular phone circuitry for communications, there are two general operation flows, illustrated in  FIGS. 4 and 5 .  FIG. 4  demonstrates the activity when the user initiates a call to the embedded phone, while  FIG. 5  demonstrates the flow when the system initiates the contact.  
         [0021]     In  FIG. 4 , this flowchart will initially be entered for setting up the system. The cellular phone circuitry  206  of the alarm system will have a telephone number. The user can therefore call this number once the innovative alarm system has been installed in a vehicle and be connected to the security system. The innovative system receives this call (step  402 ). The security system uses a personal identification number (PIN) or similar means of identification to deny access to malicious or stray calls. Thus, initially, the system will play a recorded message requesting a PIN number (step  404 ). For new customers, this can be set to an easily remembered code, such as “1234”. The user enters this number using the keypad of their telephone. If the PIN is correctly entered (step  408 ), the caller is acknowledged and allowed to continue; otherwise the caller will be disconnected (step  418 ). If this is the first time the user has called, the system will prompt the user to enter a new PIN code (step  410 ), i.e., one not so commonly used. This new PIN will be stored in memory  208  for future use. The system then prompts the user to enter the phone number at which they wish to be contacted (step  412 ). With caller recognition technology, the system can accomplish this by prompting the user with the number from which they are calling, offering a prompt to push “1” if this is the number to be contacted for intrusions or “2” to provide another number. After the phone number is received and stored, the user can be prompted to accustom himself with control of the system (step  414 ). For example, once the phone number has been accepted, the system can play a message, such as, “The emergency contact number is (999) 555-1212. To activate camera  1 , press “1”; to activate camera  2 , press “2”; etc.”.  
         [0022]     Depending on the commands entered, the system can decode the command and respond (step  416 ) appropriately to any number of commands. For example, the system can be commanded to activate a camera and transmit its picture, to scan the area using one or more cameras. These commands can be entered into the numeric keypad. For example, once a camera is activated, the system can display the view from that camera with a message to use keypad numbers “2”, “4”, “6”, and “8” to move the camera “up”, “left”, “right”, or “down”. All images, whether still or moving, are transferred digitally to the user via the phone connection. Additionally, the user can set the alarm, turn off the alarm, send a history, change PIN number, change phone number to call, etc. In future accesses, once the correct PIN is received, the system will skip the initialization process and go straight to other commands (step  416 ).  
         [0023]     In contrast to  FIG. 4 , the flowchart of  FIG. 5  is entered at the initiation of the alarm system. The sensors, which have been monitoring the activity in and around the automobile, detect a condition (step  502 ), such as movement of the car or the opening of a door while the alarm is set, that can indicate an intrusion. The innovative alarm system will not only set off a localized alarm, but will also call (step  504 ) the contact number that has been programmed into the system, such as the user&#39;s cellular telephone. Although many cellular telephone systems now have call waiting, it is possible that the alarm system will not be able to reach the user, but will be shunted to voice mail, such as when the user is in an area with poor reception or has left the phone elsewhere. The alarm system cannot determine whether a live respondent or a recorded message answers the call. Therefore, the alarm system can play a pre-recorded message and/or send a pre-set text message (step  506 ), such as, “Your car alarm is going off. Do you wish to view the scene?” Once this message has been sent, the alarm sets a timer, e.g., for thirty seconds or a minute, and waits for a response (step  508 ). The alarm system will than loop in place until either the timer times out (“yes” to step  510 ) or an instruction is received (“yes” to step  512 ).  
         [0024]     Presuming that an instruction is received first, the system can decode these instruction as programmed and act on them (step  514 ), with or without providing prompts to the user. As each instruction is performed, the system can check for further instructions (step  516 ) and continue as long as instructions are received. In one embodiment, the user is prompted to view the vehicle; if no suggestion of intrusion is found, the user can remotely turn off the alarm. Alternatively, if the user detects a problem, such as a thief or accident, the user can enter instructions to deal with the problem, such as calling the police, saving incriminating pictures, or even transmitting the pictures to the police.  
         [0025]     Backing up to step  510 , if the alarm system times out, the call must have been taken by the voice mail system. Since a voice/text message has already been left on the user&#39;s phone, the alarm system can perform a predetermined set of steps (step  518 ) and exit. For example, the user can set the system so that one or more cameras are activated for a short period of time to take a pre-set number of photos of the vehicle (such as the driver&#39;s seat, out the driver&#39;s window, and out the front windshield), then turn off the alarm. When the user is able to retrieve the message, the user can call the system (see  FIG. 4 ) and retrieve any saved information.  
         [0026]     In an alternate embodiment, sensors can be provided to alert the owner of conditions other than attempted theft. For example, the system can have sensors that are active even when an alarm is not set, such as sensors to detect an airbag being deployed or to detect damage to the vehicle that might indicate an accident. Other sensors can include drug or alcohol detectors in the interior of the vehicle. Each type of detector can have its own hierarchy of actions to perform. For example, the system can be programmed to call the owner when someone tries to open the car door, but to contact a spouse if an airbag is set off. The types and sensitivities of the sensors available are the only limits to the possibilities of such a system.  
         [0027]     In an alternate embodiment, the innovative alarm system can be programmed to provide a number of responses. For example, when the alarm system contacts the user, it may be set to turn on all cameras and to create a composite picture showing small views from various cameras for immediate display. The user can then assess the situation quickly and request larger views from individual cameras, pan the view, etc. In addition to turning off the alarm, the system can reset the alarm, disable the engine, or provide additional response mechanisms.  
         [0028]     In further alternate embodiments, the alarm system can have a hierarchy of numbers to call. If the first call does not reach a live respondent, the system can call other numbers, e.g., a user&#39;s spouse or an alarm monitoring company, until a live respondent is reached or the list is exhausted.  
         [0029]     It is important to note that while the present invention has been described in the context of a fully functioning alarm system, those of ordinary skill in the art will appreciate that the processes of the present invention are capable of being distributed in the form of a computer readable medium of instructions and a variety of forms and that the present invention applies equally regardless of the particular type of signal bearing media actually used to carry out the distribution. Examples of computer readable media include recordable-type media, such as a floppy disk, a hard disk drive, a RAM, CD-ROMs, DVD-ROMs, and transmission-type media, such as digital and analog communications links, wired or wireless communications links using transmission forms, such as, for example, radio frequency and light wave transmissions. The computer readable media may take the form of coded formats that are decoded for actual use in a particular data processing system.  
         [0030]     The description of the present invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention, the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
