20110090714 | OUTPUT APPARATUS TO OUTPUT A VITAL OUTPUT FROM TWO SOURCES - An output apparatus includes a first source of a first signal having a first state or a different second state; a second source of a second signal having a first state or a different second state; and a circuit structured to output a vital output including a first state when the first state of the first signal corresponds to the first state of the second signal and, otherwise, including a different second state. At least one of the first signal and the second signal is a static signal. The other one of the first signal having the first state and the second signal having the first state is a dynamic signal. When at least one of the first signal has the different second state of the first signal and the second signal has the different second state of the second signal, the vital output includes the different second state. | 04-21-2011 |
20110093767 | SYSTEM AND METHOD TO SERIALLY TRANSMIT VITAL DATA FROM TWO PROCESSORS - A system for serially transmitting vital data includes first and second processors to determine first and second data, a serial communication apparatus to input third data and output serial data based upon the third data, and a memory having first and second ports accessible by the first and second processors, a first memory writable by the first processor and readable by the second processor, and a second memory writable by the second processor and readable by the first processor. The first and second processors store the first and second data in the first and second memories, cooperatively agree that the first data corresponds to the second data, and responsively cause the apparatus to employ: one of the first and second data as the third data, or parts of the first and second data as the third data, and output the serial data based upon the third data. | 04-21-2011 |

20090230255 | CAB SIGNAL RECEIVER DEMODULATOR EMPLOYING REDUNDANT, DIVERSE FIELD PROGRAMMABLE GATE ARRAYS - A processor includes a first field programmable gate array (FPGA) having a first central processing unit (CPU) core programmed to perform a first function, and first programmable hardware logics (PHLs) programmed to perform a second function. A second FPGA includes a second CPU core programmed to perform a third function, and second PHLs programmed to perform a fourth function. A communication interface is between the first and second CPU cores. The first and second FPGAs are diverse. A portion of the first function communicates first information from the first CPU core to the second CPU core through the interface. A portion of the third function communicates second information from the second CPU core to the first CPU core through the interface, and, otherwise, the first function is substantially the same as the third function. The second function is substantially the same as the fourth function. | 09-17-2009 |

20120260046 | PROGRAMMABLE LOGIC APPARATUS EMPLOYING SHARED MEMORY, VITAL PROCESSOR AND NON-VITAL COMMUNICATIONS PROCESSOR, AND SYSTEM INCLUDING THE SAME - A programmable logic apparatus includes a shared memory having a first port, a second port and a third port; a first vital processor interfaced to the first port of the shared memory; and a non-vital communications processor separated from the first vital processor in the programmable logic apparatus and interfaced to the second port of the shared memory. The third port of the shared memory is an external port structured to interface an external second vital processor. | 10-11-2012 |
20120299652 | MULTI-AUTONOMOUS ELECTRONIC AMPLIFIER - An electronic amplifier includes a configurable integrated circuit device structured to synthesize at least a first signal and a second signal, scale the first signal to create a scaled first signal and scale the second signal to create a scaled second signal, create a discrete time composite signal which comprises a summation of at least the scaled first signal and the scaled second signal, create a discrete time pulse width modulated signal based on the discrete time composite signal, and generate a number of control signals based on the discrete time pulse width modulated signal. The electronic amplifier also includes a power switching stage receiving the number of control signals from the configurable integrated circuit device, wherein the number of control signals are configured to control the power switching stage, and a low pass filter coupled to an output of the power switching stage. | 11-29-2012 |
