DETAILED DESCRIPTION OF THE INVENTION
The portable device and system of the present invention is diagrammatically illustrated in FIG. 1 and includes a keyboard processing unit 10 to access and operate a remotely located computer 12, e.g. a desk top computer in a home or business office through a telephone land line connection or through a wireless cell phone connection and to access a video monitor 14, preferably a TV monitor for displaying data files stored in the desktop computer 12 on the video monitor 14 for purposes of viewing the data files and/or for editing or creating new data files. The keyboard processing unit 10 may also be used to access the remotely located computer 12 and, in turn, to access the Internet through the remotely located computer 12 for displaying information from the Internet on the video monitor 14 or for sending or receiving an e-mail through the Internet accessed through the remotely located computer 12.
A block diagram of the keyboard processing unit 10 is shown in FIG. 2 consisting of a keyboard processor 20 with an ASCII encoder and decoder 22 for receiving ASCII data and converting it to a composite video signal or for transmitting ASCII data, a keyboard 22, an input output terminal 23 and a modem 24 for connecting the keyboard processor 20, ASCII encoder and decoder 22 and the keyboard 22 to a telephone communicating device 25. The telephone communicating device 25 may be a cell phone so as to permit a wireless telephone interconnection to be made between the keyboard processing unit 10 and a modem 24 in a remotely located computer 12. A keyboard terminal processor having a keyboard, ASCII encoder and decoder and an input/output terminal is conventional. In the past a keyboard processor having an ASCII encoder and decoder and an input/output terminal was made available commercially with a display monitor but without a CPU (Central Processing Unit) and was referred to as a “dumb terminal”. The keyboard processing unit 10 of the present invention other than the keyboard may be miniaturized and incorporated into an otherwise conventional mouse type unit for portable transportation. Miniature keyboards 22 are also available. The modem 24 permits an operator to make a telephone connection between the modem in the remotely located desk top computer 12 and the terminal processing unit 10. This may be done through a wireless cell phone.
To access data in the data files stored in the remotely located desk top computer 12 it is essential to have a video monitor 14 available to display such data. The monitor 14 may represent any conventional video display but is preferably a standard TV monitor. The RF modulator 30 and RF transmitter 32 in the keyboard processing unit 10 permits wireless communication between the keyboard processor 20 and a standard TV video monitor 14 provided the standard TV monitor 14 has its power on and is turned to channel 3 or possibly channel 4. Channel 3 on a TV monitor has been designated by standardization for peripheral reception and is accepted worldwide. Accordingly, alphanumeric information can be transferred by wireless communication from the keyboard processing unit 10 to a standard TV video monitor 14 provided the alphanumeric information is radio frequency modulated for reception. The RF modulator 30 is of conventional design as is the RF transmitter 32 and are needed to establish wireless contact with the TV video monitor 14. Since the keyboard processing unit 10 is also in communication with the remotely located desk top computer 12 alphanumeric information from data files stored in the remotely located desk top computer 12 can be readily displayed on the display screen of the TV monitor 14 using the mouse 26 as if it were the mouse 26 was directly connected to the desk top computer 12. In this way the desk top computer 12 is remotely controlled and its data files accessed for viewing or for modification on the TV monitor 14. The mouse 26 and/or keyboard 22 are used to edit data files displayed on the video monitor 14 or to create new data file which are then stored in the remotely accessed computer 12.
When displaying information accessed through the Internet from the remotely accessed computer 12 on the video monitor 14 the keyboard 22 is not used. However, for e-mail messages the keyboard 22 would be used in the conventional manner. Access to the Internet from the remotely located desk top computer 12 assumes the desk top computer 12 has an internal WWW browser and will support a WWW browser application. Once the Internet is accessed an e-mail message may be transmitted or received through the internet connection from the remotely located desk top computer 12 through the wireless coupling to the standard TV monitor display 14 for creating the e-mail message with or without the attachment of data files and transferring it to a third party and/or receiving an e-mail from a third party in real time or simply to receive and view information on the internet.
It should be understood that the video monitor 14 may also be a terminal incorporated into the keyboard processing unit 10 and may have a display screen of any desired size. In this case the keyboard processing unit 10 communicates only with the remotely located computer 12 to access its files and/or with the Internet. Alternatively, the keyboard processing unit 10 may be connected to the video monitor of another computer terminal so as to permit access to the remotely located computer 12 to access its files and to display the data on the monitor of the computer terminal. Wireless access to another computer terminal is also possible.
