Figures 7A and 7B are generalized block diagrams of the keyboard of Fig. 1 with two alternate numeric keypad control circuits. Detailed Description of a Preferred Embodiment
Reference is now madt to Figs. 1 and 2, which illustrate a keyboard constructed and operative in accordance with a preferred embodiment of the present invention. The keyboard comprises an alphanumeric keypad 10, which may be identical to that used in conventional personal computers manufactured by IBM and others.
The keyboard of the present invention also preferably comprises a numeric keypad 12, typically arranged in the form of a computer numeric keyboard rather than in the form of a DTMF telephone keypad.
The alphanumeric keypad 10 is associated with a keyboard circuit 14, which may be a conventional keyboard circuit employed in commercially available IBM PC keyboards. The keyboard circuit 14 may be coupled via a connector cable to the keyboard plug socket of a computer, such as a personal computer.
The numeric keypad is coupled via a control circuit 16 to keyboard circuit 14, modem 18 and speakerphone 20. Control circuit 16 is operated by means of a control keypad 22. Control keypad 22 typically comprises three keys on the keyboard. For example, they may be a keyboard/dialpad mode switch 42, a scanner on/off switch 41 and a speakerphone on/off switch 43.
The modem 18 is coupled via serial line, such as an R 132 line, to a computer. A document scanner 24, such as a JD122 or a CCD 142DB of Fairchild Semiconductor of West Germany, may also be coupled via a serial line to the computer. Scanner 24 is also typically connected to control circuit 16 and is operable as an input device for the computer. The speakerphone 20 typically comprises a handset 30 and a loudspeaker 32 and is coupled to a telephone line, as is modem 18.
Reference is now made to Fig. 3 which illustrates the keyboard circuit 14 which is the circuitry of the TH-5539AT, RT.XT keyboard manufactured by Chickory of Taiwan utilizing the 8748 keyboard CPU manufactured by Intel of the USA. The full specification of all of the circuit compo nents appears in the drawing and therefore, for reasons of conciseness, a verbatim description thereof is not provided here. However, it will be noted that switches 36 of a numeric keypad 98 have been marked, as has a keyboard CPU 38.
Reference is now made to figs. 4A and 4B which illustrate circuitry of speakerphone 20. Figure 4A is the speakerphone specification published by Motorola Semiconductors of the USA as Data Spec Sheets MC34014 and MC34018. Figure 4B is the speakerphone specification published by Motorola Semiconductors of the USA as Data Spec Sheet
MC34118. The full specification of all of the circuit components appears in the drawings and therefore, for reasons of conciseness, a verbatim description thereof is not provided here. However, it will be noted that a secondnumeric keypad 100 is marked.
Reference is now made to Fig. 5 which illustrates the circuitry for modem 18. Figure 5 is taken from the Motorola Semiconductors Data Spec Sheet MC6860. The full specification of all of the circuit components appears in the drawing and therefore, for reasons of conciseness, a verbatim description thereof is not provided here. Reference is now made to Fig. 6 which is an illustration of circuitry for scanner 24. Figure 6 is taken from the Fairchild Charge Coupled Device Cataloguer 1984, Page 80. The full specification of all of the circuit components appears in the drawing and therefore, for reasons of conciseness, a verbatim description thereof is not provided here.
Reference is now made to Figs. 7A and 7B which illustrate two embodiments of control circuit 16 in conjunction with keyboard circuit 14 and speakerphone 20. As shown in Fig. 1, in accordance with the present invention, there is only one numeric keypad 12. The first and second numeric keypads 98 and 100 of Figs. 3 and 4B, respectively, are typically embodied in a single numeric keypad 12 comprising switches 36 (Figs. 3). For the embodiment of Fig. 7A, the switches 36 are double pole switches directly connected to both keyboard CPU 38 (shown also in Fig. 3) and a telephone dialer 40 (shown also in Fig. 4B). Keyboard CPU 38 and telephone dialer 40 are also connected to keyboard/dialpad mode switch 42 forming part of control keypad 22.
When switch 42 is in a first keyboard mode, it enables keyboard CPU 38 and disables telephone dialer 40, thereby enabling numeric and alphabetic input to the computer. When switch 42 is in a second dialpad mode, it disables the keyboard CPU 38 and enables telephone dialer 40, thereby enabling the numeric keypad 12 of the present invention to be utilized as a telephone keypad.
In accordance with an alternate embodiment of the present invention and as shown in Fig. 7B, switch 42 is connected to keypad CPU 38 and to telephone dialer 40. As in the previous embodiment, when switch 42 is in the first mode, the keyboard is enabled and the telepLone dialer 40 is disabled. The keyboard data is sent, via a serial data line, to a computer (not shown). However, in this embodiment, when the telephone dialer 40 is enabled, the keyboard CPU 38 remains enabled and receives the data from numeric keypad 12. The serial data line is switched, via switch 47 which is operated by switch 42, to send data to the now enabled telephone dialer 40. In this embodiment, telephone dialer 40 is modified, in a manner known to one skilled in the art, to receive keyboard signals and to encode them to DTMF signals for the speakerphone 20.
In accordance with the present invention, as shown in both Figs. 7A and 7B, when the numeric keypad 12 is utilized as a telephone keypad, the keys +, -, Enter and *, are redefined to perform the redial, auto, memory and flash features of a speakerphone 20, respectively.
It will be appreciated that the entirety of keys of both the alphanumeric and numeric keypads 10 and 12, respectively, can be utilized for advanced telephone features, as required. For the embodiment of Fig. 7A, the entirety of keys of keypads 10 and 12 can be implemented as double pole switches. For the embodiment of Fig. 7B, the entirety of keyboard data can be sent to the telephone dialer 40. It will be appreciated by persons skilled in the art that the present invention is not limited to what has been particularly shown and described hereinabove. Rather the scope of the present invention is defined only by the claims which follow:
