    摘要: An electronic apparatus having a keyboard and an output device, such as a thermal printer unit. The apparatus, including its printer unit, is burn-in tested by an electronic system built into the apparatus. The system includes a memory, a circuit for storing a preselected or predetermined alphanumeric code in the memory and a circuit for repetitively causing the printer unit to print the contents of the memory. A delay system may be incorporated which causes the apparatus to enter a wait mode between printing operations. The period of time that the system is in the wait mode may be either a fixed duration or of a selected duration. In the embodiment disclosed, the apparatus is an electronic calculator.

    摘要: The equation operating system is an improved data and command entry format together with a compatible operation system for use with electronic data processing apparatuses, most particularly with scientific calculators which provide an alphanumeric display of entered equations. This invention also includes a unary operation implementation technique, whereby the operand may be entered either before or after the unary operation.

    摘要: The equation operating system is an improved data and command entry format together with a compatible operation system for use with electronic data processing apparatuses, most particularly with scientific calculators which provide an alphanumeric display of entered equations. This invention provides an implied multiplication having differing hierarchical ranks when one of a member of a predetermined prefix set entry is followed by one of two differing suffix set entries. Each of these implied multiplications have a differing hierarchical rank than that of explicit multiplication.

    摘要: Calculator having a keyboard in which one or more keys have labels created by a display and subject to changing interactively as the user desires. Typically, advanced scientific-programmable calculators may have too many functions to be adequately included on the keys of the keyboard associated therewith. In such calculators, certain functions require a plurality of keys to be actuated in order to be performed. Thus, such keyboards tend to be cluttered an confusing to the user. Thus, a keyboard is proposed having a small number of keys labeled with different functional labels as the user proceeds through a menu or tree structure containing all the desired functions. Keys in a certain group of keys on the keyboard are thereby subject to redefinition or relabeling so as to provide a variety of functions.
