In facsimile (fax) transmissions, data is encoded for transmission over telephone lines or radio broadcast for print out at a remote location.
When performing a fax transmission, after making a connection with a receiving fax machine, a transmitting fax machine scans an image including, for example, text and/or graphics, by reading a very small area of the image at a time. The fax machine decides whether the area read is light or dark and digitizes the area by assigning the area a number such as “0” for white and “1” for dark. Then the fax transmits the number to a remote facsimile receiver. The receiver, for example, prints out the received image on a print media. This process continues as the transmitting machine scans a series of small areas horizontally across the image, and transmits that information to the remote receiver. The transmitting fax then scans a next lower line and so on until the entire image has been scanned, digitized, and transmitted.
As fax machines have increased in popularity, features have been added to fax machines to make them more versatile and convenient. For example, some fax machines have the ability to scan and transmit color images. Some fax machines include auto-dialing and fax number storage. There is a continuing quest to improve fax machines by increasing their versatility and convenience of use.
In accordance with the preferred embodiment of the present invention, a fax is sent. A user selects a phone number for a fax destination from a database residing on a handheld device. The phone number is sent from the handheld device to a fax machine via wireless communication. A fax transmission is sent by the fax machine to the fax destination.
Fax machine 10 is shown to be in wireless communication with a handheld unit 20, as illustrated by arrows 29. A handheld unit is a unit that is designed to be used while being held in one hand. Handheld unit 20 is, for example, a cell phone or a personal digital assistant (PDA). For example, a desktop computer and a laptop computer are not designed to be used while being held in one hand and so are not handheld devices as the term is used herein.
Handheld unit 20 is shown to include a display 22, a keypad 25, a memory 24, a controller 23 and a wireless communication module 21. For example, memory 24 is used to store a phone number database 26. For example, keypad 25 includes keys located separate from display 22 on handheld unit 20. Alternatively, keypad 25 is integrated with display 22 in a touchpad configuration. For example, wireless communication module 21 facilitates wireless communication using, for example, radio frequency signals or infrared signals using one or more standard or proprietary protocols. For example, controller 23 includes a computer processor that executes program code stored in memory 24. The block diagram of handheld unit 20 is meant to be illustrative only. That is, a person of ordinary skill in the art would recognize that handheld unit 20 can be implemented with more or fewer modules arranged in a variety of configurations depending upon the function and features of handheld unit 20.
In a block 32, the user loads the document to be faxed into fax input 60. In a block 33, the user selects from phone number database 26 one or more fax numbers for the fax destination. In a block 34, the user uses keypad 25 and/or display 22 to select a send fax option. In a block 35, handheld unit 20 uses wireless communication module 21 to send to fax machine 10 an initiate fax command. The initiate command is accompanied by the one or more fax numbers the user selected from phone number database 26. If specified by the user, the initiate command can also include a name, address and/or other personal information associated with the fax number for inclusion in a fax cover sheet automatically generated by fax machine 20. Fax machine 20 then initiates sending a fax to the one or more fax numbers the user selected from phone number database 26 along with any other personal information received.
In a block 36, handheld unit 20 uses display 22 to query the user about updating phone number database 18 in memory 15 of fax machine 10 with the one or more fax numbers. In a block 37, handheld unit 20 processes the response from the user. If the user requests an update of phone number database 18 in memory 15 of fax machine 10, in block 38, handheld unit 20 uses wireless communication module 21 to send to fax machine 10 an update fax phone book command. The update fax phone book command is accompanied by the one or more fax numbers the user selected from phone number database 26. The update fax phone book command also is accompanied by a name, address and/or other personal information associated with the fax number for inclusion in phone number database 18 in memory 15 of fax machine 10. In a block, 39 the fax is complete.
In a block 42, fax machine 10 uses wireless communication module 16 to locate and establish contact with any nearby handheld device. When fax machine 10 discovers handheld device 20, fax machine 10 establishes communication with handheld unit 20.
In a block 43, fax machine 10 uses wireless communication module 16 to send to handheld unit 20 a prompt command instructing handheld unit 20 to prompt the user for one or more phone numbers for the destination of a fax.
In a block 44, handheld unit 20 opens phone number database 26 and uses display 22 to display at least a portion of open phone number database 26 to the user.
In a block 45, the user selects from phone number database 26 one or more fax numbers for the fax destination. The user uses keypad 25 and/or display 22 to indicate the one or more fax numbers for the fax destination(s) that are to be provided to fax machine 10. Handheld unit 20 uses wireless communication module 21 to send to fax machine 10 the one or more fax numbers the user selected from phone number database 26. If specified by the user, the initiate command can also include a name, address and/or other personal information associated with the fax number for inclusion in a fax cover sheet automatically generated by fax machine 20. Fax machine 20 then initiates sending a fax to the one or more fax numbers the user selected from phone number database 26 along any other personal information received.
In a block 46, handheld unit 20 uses display 22 to query the user about updating phone number database 18 in memory 15 of fax machine 10 with the one or more fax numbers. In a block 47, handheld unit 20 processes the response from the user. If the user requests an update of phone number database 18 in memory 15 of fax machine 10, in block 48, handheld unit 20 uses wireless communication module 21 to send to fax machine 10 an update fax phone book command. The update fax phone book command is accompanied by the one or more fax numbers the user selected from phone number database 26. The update fax phone book command also is accompanied by a name, address and/or other personal information associated with the fax number for inclusion in phone number database 18 in memory 15 of fax machine 10. In a block 49, the fax is complete.
