FACSIMILE SIGNAL INTERCEPTION DEVICE
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to telephone answering devices and, more particularly, to a device designed to prevent incoming facsimile transmissions to a telephone voice-only line.
2. Description of the Related Art
As conceived, the invention prevents incoming facsimile transmissions to a telephone voice-only line. The incoming telephone call is detected and a determination is made if the call is that of a facsimile machine attempting to make a connection with another facsimile machine. If not, then the call is forwarded to a regular conventional phone. If so, then the incoming caller's number is identified utilizing Caller ID, and a reply message is sent to inform the first caller of the error. In the related art, many devices are know that allow for the automatic switching of telephone signals. In the consumer arena, automatic telephone answering machines are commonly used to receive calls and record messages when the user is unavailable . Another problem occurs from the use of facsimile devices. Facsimile machines generally are capable of acknowledging an incoming facsimile transmission. However, when attempting to communicate an outgoing message, facsimile machines are not capable of acknowledging and remembering that outgoing transmissions are not contacting similar connection devices, and rather rely heavily on personal intervention to maintain database information for use with polling, forwarded, or broadcast facsimile messages. The end result of this is that the recipient of an unwanted facsimile message to their voice phone or answering machine may suffer through a series of such incomplete attempts until a user at the sending end provides
the necessary intervention.
SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to provide an improved telephone answering device.
It is a feature of the present invention to provide an improved telephone answering device designed to prevent incoming facsimile transmissions to a telephone voice-only line . Briefly described according to one embodiment of the present invention, a facsimile signal interception device is provided that will detect an incoming telephone call. If the telephone signal is of the analog type commonly found in the United States and referred to as POTS, the signal is then analyzed by a facsimile analysis circuit which looks for the trademark high-pitched whine of a facsimile machine attempting to make a connection with another facsimile machine. In the event that the call is not that of a facsimile machine, an output from the facsimile analysis circuit energizes a relay which, thus forwarding the call to a regular conventional phone, where it might be answered by a user, a telephone answering machine or other typical conventional device. Should the call be from a facsimile machine, a Caller ID circuit makes note of the incoming caller's number. Simultaneously, the facsimile analysis circuit initializes a timing module, which allows a delay for the facsimile machine which placed the errant call, to complete its transmission cycle and reset itself. At this point the output of the timing module energizes an outgoing call circuit, which places an automatic call to the facsimile machine as identified by the caller ID furnished by the Caller ID circuit. When or if the errant calling facsimile machine answers, a predetermined facsimile message, stored in an electronically stored facsimile message circuit is sent. An advantage of the present invention is that is prevents
errant incoming facsimile calls from ringing to the user's voice phone.
Another advantage of the present invention is that it will return a call to the errant facsimile machine in order to notify it of the initial error.
Further, a preferred embodiment of the present invention has the capacity to generate a facsimile transmittable text message, thereby allowing the user to customize the return message being sent .

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention will become better understood with reference to the following more detailed description and claims taken in conjunction with the accompanying drawings, in which like elements are identified with like symbols, and in which:
FIG. 1 is a functional schematic block diagram of the facsimile signal interception device 10 according to a preferred embodiment of the present invention; and FIG. 2 is a flow diagram depicting the logic sequence of the facsimile signal interception device 10.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring first to FIG. l,a facsimile signal interception
device 10 is depicted according the preferred embodiment of the present invention. An incoming telephone call is present at an input jack 15. The telephone signal would be of the analog type commonly found in the United States and referred to as POTS. The signal is then analyzed by a facsimile analysis circuit 20, which looks for the trademark high- pitched whine of a facsimile machine attempting to make a connection with another facsimile machine. In the event that the call is not that of a facsimile machine, an output from the facsimile analysis circuit 20, energizes a relay 25 which connects the input jack 15 to a set of output jacks 30, thus forwarding the call to a regular conventional phone, where it might be answered by a user, a telephone answering machine or other typical conventional device. Should the call be from a facsimile machine, a Caller ID circuit 35 makes note of the incoming caller's number, should it be available, for later use. Simultaneously, the facsimile analysis circuit 20, initializes a timing module 40. The timing module 40, envisioned to have a cycle time of 2 minutes, allows the facsimile machine which placed the errant call, to complete its transmission cycle and reset itself. At this point the output of the timing module 40 energizes an outgoing call circuit 45, which places an automatic call to the facsimile machine as identified by the caller ID furnished by the Caller ID circuit 35. When or if the errant calling facsimile machine answers, a predetermined facsimile message, stored in an electronically stored facsimile message circuit 50 is sent. It is envisioned that the message stored in the electronically stored facsimile message circuit 50 would warn the owner of the errant facsimile machine that an incorrect number was dialed. Stronger wording warning the owner to remove the subject number from the facsimile machine's dialing memory or face possible legal ramifications could also be used. Upon successful sending of the warning facsimile, the invention is ready to repeat the above-mentioned process.
Referring next to FIG. 2, a logic flow diagram associated
with the facsimile signal interception device 10 is depicted. The process begins at a first functional block 55 where the facsimile signal interception device 10 waits for and receives an incoming call. Upon receipt of a call, a first operational block 60 decides if the said incoming call is a facsimile or a non-facsimile phone call. In the case of a negative response, a second functional block 65 then returns control to the regular phone system by forwarding the call to a conventional telephone or telephone system. In the case of positive response at the first operational block 60, the system records the errant facsimile's machine originating telephone number by use of a Caller ID system which is well-known in the art. The system then disconnects from the errant facsimile transmission, so as to not occupy the telephone connection any more than necessary, and then begin an internal timing cycle, as indicated by a fourth functional block 75 and a fifth functional block 80 respectively. Upon completion of the timing cycle, a sixth functional block 85 then places an outgoing call to the number as stored by the third functional block 70, as aforementioned described. In case of an unsuccessful connection, as determined by a second operational block 90, the control returns to the fourth functional block 75 where the process repeats. In the case of a positive connection, a seventh functional block 95 then transmits the electronically stored facsimile message alerting the errant facsimile owner to the incorrect number that was being used. A third operational block 100 ensures that the message was delivered to the errant facsimile user by way of a positive response that returns control the first functional block 55, or to the fourth functional block 75 in the case of a negative response .
It is envisioned that other styles and configurations of the present invention can be easily incorporated into the teachings of the present invention, and only one particular configuration shall be shown and described for purposes of clarity and disclosure and not by way of limitation of scope.
The preferred embodiment of the present invention can be used by the common user in a simple and effortless manner.
Once installed, the facsimile signal interception device 10 operates in a transparent manner, such that its operation is not apparent to the unknowing user. The operation of the facsimile signal interception device 10 is best described in conjunction with FIG. 1, through FIG. 2.
After acquisition of the facsimile signal interception device 10, the user would first connect the facsimile signal interception device 10 by terminating their incoming phone line at the input jack 15 and the balance of their internal phone system to the output jacks 30. Due to the nature in which the facsimile signal interception device 10 must seize control of the phone line, it cannot be added in an electrically parallel connection to the user's existing phone system, by simply plugging into an extension jack. After connection of a suitable power source to the facsimile signal interception device 10, it is ready for automatic use.
Upon receipt of an incoming call, the facsimile signal interception device 10 will determine if said call is a facsimile transmission. If not, the facsimile signal interception device 10 will forward the call on to the output jacks 30, for normal usage. If so, the facsimile signal interception device 10 will call back the errant facsimile machine and transmit a warning facsimile to prevent further occurrences as defined by FIG. 2.
The foregoing descriptions of specific embodiments of the present invention have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and its practical application, to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are
suited to the particular use contemplated. It is intended that the scope of the invention be defined by the Claims appended hereto and their equivalents. Therefore, the scope of the invention is to be limited only by the following claims.
