TLDR
In this article, a method of fault protection for a microcomputer system is presented, which determines whether the system returns to a normal or special operating mode if a fault is detected by determining the microprocessor's past history before the fault occurred.Abstract:
The present invention is a method of fault protection for a microcomputer system. The method determines whether the system returns to a normal or special operating mode if a fault is detected by determining the microprocessor's past history before the fault occurred thereby allowing the microprocessor to get back on track in an appropriate manner.read more

Methods for automatically locating url-containing or other data-containing windows in frozen browser or other application program, saving contents, and relaunching application program with link to saved data
Marco Lopez,Scott Elliott +1 more
TL;DR: In this paper, a machine-automated system tries to save vital-data of a crashed or otherwise frozen application program by identifying the apparently-frozen program; identifying one or more windows within the identified program that are most likely to immediately contain data which the user is likely to consider as vital and in need of saving; and instructing the frozen program to itself transfer the data of said one of said identified windows to a separate, data-saving thread.
Patent
Microcontroller having an EPROM with a low voltage program inhibit circuit
TL;DR: In this article, a low voltage program inhibit (LVPI) circuit is integrated into the EEPROM to prevent the CPU from programming or erasing the read-only-memory (EEPROM).
Patent
Methods for automatically locating data-containing windows in frozen applications program and saving contents
TL;DR: In this paper, a machine-automated system tries to save vital data of a crashed or otherwise frozen application program by attempting to revive a program that has apparently become frozen; identifying the apparently-frozen program; and sending one or both of a SAVE and a CLOSE command message to each of the identified one or more windows so as to thereby cause that window to itself save its vital data contents and to thereafter gracefully close itself.
Patent
Repeat instruction with interrupt
TL;DR: In this paper, a processor for processing an interruptible repeat instruction is provided, where the repeat instruction may include an immediate operand specifying a loop count value corresponding to the number of times that the loop is to be repeated.

Data terminal with capability of checking memory storage capacity as well as program execution parameters
TL;DR: A data input/output terminal includes a central processing unit, a random access memory (RAM), a display unit, and various data entry devices for inputting and outputting data to a host processor as mentioned in this paper.
Patent
Memory contents confirmation
TL;DR: In this paper, the authors present a method for first checking the memory contents when the power-off command has been activated, and then storing the results of the checking in a specific area of the RAM.
Patent
Device for testing programs for numerical control of machine tools
TL;DR: In numerical controls of machine tools, the downwards (lengthwise) sum of the programmed information of each system program memory (SP1) is stored in an additional memory as mentioned in this paper, for later checking of the memory contents, the downward sums of the respective memories on the control side are formed and are compared with the stored information.
Patent
Diagnostic test for programmable device in a mailing machine
TL;DR: In this article, a test method and apparatus for testing the contents of a programmable device in a mailing machine is presented, where each bit of the programmable devices under test is added in an accumulator and the resulting sum is displayed on the machine's control panel display.
