Abstract: A voice-controlled elevator security system. Access to an elevator system servicing a plurality of landings of a structure is controlled by comparing a voice signal of a potential user of the elevator system with stored voice signals of all authorized users. The comparison is accomplished by first digitizing the potential user's voice signal and comparing it, on a bit-by-bit basis, with a digital representation of the voice signals of all authorized users. Various criteria can be established for determining the number of binary bits that must agree to conclude that the potential user is an authorized user. Once this determination has been made, the authorized user can initiate car call signals for those landings to which the authorized user is permitted access.

Abstract: A monitoring circuit for digital circuits is disclosed. The monitor is primarily applicable to digital circuits which operate in a cyclic mode with the digital patterns generated during each cycle being repeated in a predictable manner. A predetermined number of expected bit patterns are stored in a programmable memory. The stored bit patterns correspond on a bit-by-bit basis to the bit patterns generated by the circuit being monitored when this circuit is operating normally. In the self-scan mode each pattern generated by the circuit being monitored is compared to each of the patterns stored in the memory in a sequential manner. Each time a pattern generated by the circuit being monitored is found to identically correspond to a pattern stored in the memory a valid pattern pulse is generated which steps a down counter one count. If this process does not result in the down counter being stepped the expected number of times during the operating cycle, a flip-flop is set indicating that the circuit being monitored has malfunctioned. Provisions are also included for counting the transitions of a digital signal during predetermined portions of the cycle of the circuit being monitored and for monitoring the polarity and amplitude of a predetermined number of analog voltages. The result of all of these tests are combined to generate a signal indicating the operational status of the circuit being monitored. The monitoring circuit may also be operated in a one-to-one correspondence mode. In this mode each bit pattern generated by the circuit being monitored are compared to bit patterns stored in a selected memory location. If these bit patterns are not identical, a malfunction signal is generated.

Abstract: A digital rod position indicator having discrete coils spaced along the travel path of an elongated magnetically permeable member stores in digital form compensation signals for automatically adjusting the location relative to the coils at which the digital output signal representative of the position of the end of the elongate member transitions from one code to the next. The appropriate compensation signal is addressed using the digital output signal and a correction factor which takes into account the direction of movement including reversals.

If the comparison satisfies an established criterion, the potential user is determined to be an authorized user.

Abstract: An inadvertent approach to criticality in a nuclear fueled electric power generating unit is detected and an alarm is generated through on-line monitoring of the neutron flux. The difficulties of accurately measuring the low levels of neutron flux in a subcritical reactor are overcome by the use of a microcomputer which continuously generates average flux count rate signals for incremental time periods from thousands of samples taken during each such period and which serially stores the average flux count rate signals for a preselected time interval. At the end of each incremental time period, the microcomputer compares the latest average flux count rate signal with the oldest, and preferably each of the intervening stored values, and if it exceeds any of them by at least a preselected multiplication factor, an alarm is generated. The interval and multiplication factor are chosen such that an alarm is generated early enough in the event to provide adequate time for an automatic system or the operator to take action which prevents the reactor from going critical yet minimizes the likelihood of a spurious response. As applied to a pressurized water reactor system, boron dilution events are detected in time that the chemical and volume control system can be isolated and the valves for the refueling water storage tank can be opened to inject highly borated water into the reactor coolant system to keep the reactor subcritical.
