A computing device within a reflective memory system includes a memory block and a special purpose processor. The memory block includes a plurality of memory areas, which are configured to store data of a corresponding one of a plurality of external devices. The special purpose processor is configured to intercept a write request. The write request is associated with a first external device of the plurality of external devices, and the first external device is associated with a first memory area of the plurality of memory areas. The special purpose processor is configured to determine whether the write request is valid or invalid, write the data of the first external device to the first memory area if the write request is valid, and prevent the data of the first external device from being written to the memory block if the write request is invalid.

Systems and methods for protection of reflective memory systems

A method, system and/or apparatus for remotely monitoring the operation of a radiation sensor may include a radiation sensor configured to detect a presence of radiation in the area, the radiation sensor including a Geiger-Muller tube, a test signal generator configured to generate a high frequency test signal used to test the radiation sensor, the high frequency test signal transmitted to the radiation sensor, and a test signal detector configured to detect a response of the radiation sensor to the test signal, and determine whether the radiation sensor is operating correctly.

Method, system and apparatus for providing an electronic signal for the surveillance and testing of Geiger-Muller radiation sensors

A computing system includes at least a first division and a second division. The first division has a first clock rate and the second division has a second clock rate. The computing system includes a first processor configured to execute a task on the first division and a second processor configured to execute the task of the second division. The task executed on the first division operates according to the first clock rate, and the task executed on the second division operates according to the second clock rate. A method of executing a task in order to reduce common mode failures in a computing system includes varying a program speed of each of the plurality of divisions such that the task, when executed on a corresponding one of the plurality of divisions, operates at a clock rate according to the corresponding one of the plurality of divisions.
