Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
For use in conjunction with a hand-held calculator having a housing, an input keyboard on said housing, a computing module in said housing including input terminals coupled to the keys of the keyboard, and a display on said housing coupled to the output of the computing module; an interface of entering numeric information from an independent companion device into the computing module while maintaining full portability and independent use of said calculator, comprising: a multipin connector element affixed to the housing of said calculator; a plurality of conductors for directly coupling pins of said connector element to the numerical input terminals of the computing module, said conductors being connected in parallel with the inputs from said keyboard; a multipin connector mate element; and a plurality of conductors coupled to the pins of said mate element and adapted for connection to said independent companion device.
Claim 2
Dependent Claim
144 words
For use in conjunction with a hand-held calculator having a housing, an input keyboard on said housing, a computing module in said housing including input terminals coupled to the keys of the keyboard, and a display on said housing coupled to the output of the computing module; an interface of entering numeric information from an independent companion device into the computing module while maintaining full portability and independent use of said calculator, comprising: a multipin connector element affixed to the housing of said calculator; a plurality of conductors for directly coupling pins of said connector element to the numerical input terminals of the computing module, said conductors being connected in parallel with the inputs from said keyboard; a multipin connector mate element; and a plurality of conductors coupled to the pins of said mate element and adapted for connection to said independent companion device.
Claim 3
Dependent Claim
57 words
The interface as defined by claim 1 wherein said calculator keyboard input is a one-out-of-N input and said device for generating numerical information generates said information in a binary coded form, and further comprising converter means coupled between said device and the conductors coupled to said connector mate element for converting the binary code to one-out-of-N form.
Claim 4
Dependent Claim
144 words
For use in conjunction with a hand-held calculator having a housing, an input keyboard on said housing, a computing module in said housing including input terminals coupled to the keys of the keyboard, and a display on said housing coupled to the output of the computing module; an interface for entering numeric information from an independent graphical digitizer into the computing module while maintaining full portability and independent use of said calculator, comprising: a multipin connector element affixed to the housing of said calculator; a plurality of conductors for directly coupling pins of said connector element to the numerical input terminals of the computing module, said conductors being connected in parallel with the inputs from said keyboard; a multipin connector mate element; and a plurality of conductors coupled to the pins of said mate element and adapted for connection to said independent graphical digitizer.
Claim 5
Dependent Claim
144 words
For use in conjunction with a hand-held calculator having a housing, an input keyboard on said housing, a computing module in said housing including input terminals coupled to the keys of the keyboard, and a display on said housing coupled to the output of the computing module; an interface for entering numeric information from an independent graphical digitizer into the computing module while maintaining full portability and independent use of said calculator, comprising: a multipin connector element affixed to the housing of said calculator; a plurality of conductors for directly coupling pins of said connector element to the numerical input terminals of the computing module, said conductors being connected in parallel with the inputs from said keyboard; a multipin connector mate element; and a plurality of conductors coupled to the pins of said mate element and adapted for connection to said independent graphical digitizer.
Claim 6
Dependent Claim
53 words
The interface as defined by claim 3 wherein said calculator keyboard input is a one-out-of-N input and said graphical digitizer generates information in binary coded form, and further comprising converter means coupled between said graphical digitizer and the conductors coupled to said connector mate element for converting the binary code to one-out-of-N form.
