A personal identification system for use in security and various other types of pattern matching applications provides accurate recognition of a known person. This system uses a large quantity of course but inexpensive sensors to create a profile of a person seeking to enter the controlled space or to take other action. These sensors measure different statistically independent characteristics of the person, such as height, weight, stride, voice timbre, and time to perform various functions. The measurements so obtained may individually be of very low resolution. They are used to search a data base of patterns related to admissible individuals. Active agent methods are used to support learning and adaptation of the sensor set to address sensor drift and individual characteristic changes over time. A combination of many parameters will identify a person with very low probability of both false negative and false positive errors. The resulting low sensor resolution required allows such a system may be implemented at very low cost in comparison to other biometric systems.

A computer system especially for solution of real time inference problems is disclosed. The system includes a systolic cellular processor which provides predictable and responsive real time operation and fine grain programmability. The system comprises a plurality of separate processor cells each having its own local memory, the cells running simultaneously and operative to execute their respective program instructions. A global memory is coupled via a global bus to the processor cells and provides data to the cells and stores data from the cells. The bus provides effectively simultaneous access of all cells to the global memory. A further feature of the system is a novel parallel programming language using English syntax and which provides synchronous and predictable binding of code to each cell. A graphic work station is provided as a user interface to provide visual access to each cell or to cell groups for ease of control. The system can also function to emulate large scale integrated circuit processors by reason of the fine grain programmed operation of the system.

A parallel process controller capable of expandable, parallel operating multi-function control of processes without degradation of performance. The process controller comprises up to N (where N is a positive integer) programmable command memory modules, and also comprises data memory modules, an input/output system, a high speed data bus (N-bus) and a general timing and control unit. Each command memory module performs the functional equivalent of a central processing unit with storage of instruction lines designatable by a user via a programming panel. Each command memory module operates autonomously, without regard to the other command memory modules and cyclically solves each of the user instruction lines in a short, fixed length of time. Each data memory module supplements data storage in the command memory modules. The N-bus is a high speed data bus that cyclically interconnects for a fixed length of time each command memory module during one of N control signals generated by the general timing and control unit, to any of the data memory modules and to the input/output system. During this length of time, the selected command memory module may address, read, or write in any location in any data memory module. An interconnectable programming panel may monitor, program, or control line status indicators for any instruction line within any command module or any line within any data memory module. The programming panel communicates with the controller via a dedicated channel of the input/output system.

A systematic data memory error detection and correction apparatus periodically reads data from each addressable memory location, determines the presence or absence of an error in the addressed data memory location and, if an error is detected, corrects the error and writes the corrected data back into the addressed memory location. The apparatus may include circuitry for logging those areas of the data memory where errors have been detected, such logging showing either the address location where an error is detected or alternatively indicating the repetitiveness of an error at any particular addressed memory location. Such data logging facilitates determination of hardware or 'hard' type errors as distinguished from non-hardware or 'soft' type errors. The latter type errors are typically found in dynamic random access memories (dynamic RAM's) which occasionally and randomly have errors due to bombardment of cosmic energy and alpha particles, the latter typically due to minute radioactive elements in silicon materials used in the fabrication of such memories. When the present apparatus is used in conjunction with dynamic RAM's, the error detection and correction is typically performed during 'refresh' times which are necessary for maintaining proper stored charge in such devices. By so doing, the access performance of the memory is not degraded by the error detection and correction apparatus.

Systematic memory error detection and correction apparatus and method

A programmable sequence controller is disclosed utilizing digital and analog inputs in order to generate digital output driver signals for the control of external systems or devices. The controller emulates mechanical sequence drums so that at any one time each of the simulated drums within the controller executes one of the addressable drum lines programmed within the drum. Each line of each simulated drum can be programmed to specify the energization or deenergization of any output driver as well as the energization or de-energization of any memory bit utilized by the controller in order to provide communication between drums. Each drum may also be programmed to have one or two sets of exit conditions, which if met, cause the controller to effectively rotate the drum to a specified drum line and execute this new drum line during the next scan of the controller. The controller can also sense emergency conditions and cause any or all of the drums to rotate to a specified line regardless of the drum line then being executed by the controller for each of the drums. An improved power-down, power-up circuitry insures an ordered and complete shutdown of the controller if any of a number of conditions exist, including utility AC failure and impending failure of several of the power supply voltages. Handshaking circuitry between the power supply and the remainder of the controller insures that the controller maintains memory validity for all types of shutdown situations, including momentary losses of any supply voltage. The programmable sequence controller includes a clock-calendar capable of continued operation during periods of extended power outages. The clock-calendar can be utilized in any drum line to form part of the control scheme. All programming of the simulated drum lines is performed through an interconnected data communication device such as a teletypewriter and utilizes a simple user-oriented language, with monitoring and diagnostic capability to facilitate debugging.

A parallel process controller capable of expandable, parallel operating multi-function control of processes. The process controller comprises programmable command memory modules, data memory modules, an input/output system, a programming panel, and a high speed data bus (N-bus). The input/output system comprises input/output channels for intercommunication between the process controller and the external world. This intercommunication is repetitively updated for each input/output channel in an error-free manner that operates autonomously with respect to the remainder of the process controller. Each input/output channel incorporates a first dedicated area of a dedicated data memory module in which information is read and a second dedicated area of the data memory module in which information is written. The information read from the first dedicated area is transferred to external devices via a local modem-remote modem combination. Likewise, data written into the second dedicated area of the dedicated data memory module is transferred from the external device via the same remote modem-local modem combination.

A programmable printer is provided which is capable of printing alphanumeric internally pre-stored data or data information and alphanumeric externally supplied data or data information either separately or in combination with each other. The alphanumeric printout of the printer may be inverted in a manner to allow its visual reading in what would otherwise be an 'upside-down' configuration. The programmable printer incorporates a microprocessor for the proper addressing, interpretation and manipulation of input commands, timing information, paper-sensing information, external data information, and internal stored data information, so as to generate output information that seeks the desired data information, whether external or internal, and that drives a printer logic interface and output status lines and print drive interface so as to print the desired information and to monitor the status of the printer. The printer also includes an alphanumeric print mechanism incorporating twenty-one character columns per line of printout, a timing pulse generating means, a paper sensing means, and a lid detector switch; a printer logic interface that provides electrical isolation between the print mechanism and the microprocessor and provides the actuating power to operate the print mechanism's hammers as well as means for amplifying and shaping the timing pulses and paper sensing pulses from the print mechanism; a command interface that provides electrical isolation between the command information and the microprocessor as well as providing for the proper selection, shaping and timing of the command information; a data interface that provides electrical isolation between the external data information and the microprocessor as well as providing for the proper selection, shaping and timing of external or internal data information; a programmable 'read only' memory for the storage of various messages; a set of output status lines for the transmission of information to the outside world and for the indication of various conditions of the printer; and a print drive interface that provides for the electrical isolation, shaping and amplification of the output status lines information and the print drive information.

A miniaturized computer controller system utilizes reprogrammable 'read only' ultraviolet memory chips instead of conventional core memories to store a control program comprising variable information regarding all electrical elements in all electrical circuit lines of the controller. The memory chips are reprogrammable within the controller and thus delicate removal of the chips for reprogramming is eliminated. The controller utilizes a central processor removably interfitting with a reprogramming module that also communicates with a programming panel. When in a 'monitor' mode, the programming panel, in conjunction with the reprogramming module, allows the operator to view any particular electrical circuit line while the controller is operating. A scroll switch on the programming panel further allows the operator to view sequentially higher or lower numbered electrical circuit lines while a trace switch provides for examining any electrical circuit line to which a currently viewed element is referenced. When in a ' program' mode, the programming panel, in combination with the reprogramming module, replaces the variable memory 'read only' chips and allows the controller to continue operation while the operator is programming, adjusting, or de-bugging the electrical circuit lines. Following the programming of the electrical circuit lines with the desired electrical elements, the information regarding these lines is transferred to the reprogrammable 'read only' memory chips when the programming panel is in a 'write' mode. In this mode all the information previously stored in the memory chips is first erased by ultraviolet light, followed by the insertion of the new information regarding the electrical circuit lines. Following the transferral of information to the memory chips, the reprogramming module is disconnected from the central processor and replaced by a removably interfitting power supply module, whereby the system operates with electrical circuit line information stored in the reprogrammable memory chips.
