The calculator includes a keypad, a display screen, and circuitry internal to the calculator. The circuitry includes a microprocessor, a storage unit for storing data and programs for execution by the microprocessor to implement calculator functions. The storage unit has stored therein a disable/re-enable program that recognizes a first predetermined calculator event and in response thereto disables one or more programs, and that recognizes a second predetermined calculator event and in response thereto re-enables the disabled program. The invention allows Apps, programs and additional information that may be embedded within the Apps and programs in a calculator or other handheld calculating device to be rendered temporarily inaccessible within a relatively short period of time, and then to be restored to the calculator, again, in a relatively short period of time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Functionality disable and re-enable for programmable calculators","description":"A handheld calculator with disable/re-enable capability.
