A memory system for storing data comprising a plurality of sets of bits. The system includes a memory section having a pair of ports and a plurality of memory banks. Each one of the memory banks has a plurality of addressable memory units. Each one of the memory units has: memory address control terminal; and data terminals. Each one of the sets of data is fed to the data terminals of a corresponding one of the memory units in each one of the memory banks. The system includes a pair of address c...

A power distribution system in which the loads are connected in series to a current source. At each load, a current source to voltage source convertor provides alternative current paths. A serial power distribution current path includes a modulated switch (e.g. a pulse width modulated switch) to control the amount of power delivered to the load via a load current path. The load current path includes a diode which couples a capacitor across the switch, providing a semi-regulated voltage input to ...

A strain tolerant ceramic coating, preferably for use as an abrasive coating on a substrate is provided. The coating is prepared from a yttria and zirconia powder having an average particle size less than 40 microns. The coating is formed by depositing the powder on the substrate by a plasma spray process. The as-applied coating contains essentially no macrocracks, but a post-stressed coating contains a random distribution, population, and orientation of microcracks and macrocracks.

A fault tolerant platform is provided that comprises two systems running pairs of processes in the active and standby state, one process from each pair running on each system. Each system comprises a fault-tolerance controlling process, first communication channels provided between the fault-tolerance controlling process and the processes in the active or standby state running on its system, and second communication channels provided between the fault-tolerance controlling processes. Management ...

An inflatable device having a safety system provided by having at least two separate and distinct independently inflatable bladders contained within the outer shell of the device. Each of the bladders is designed when fully inflated to fully inflate the shell, but during use one of the bladders is not fully inflated and has a projected area of no greater than 50% of the projected area of the inflated shell.

This invention pertains to rice plants, plant material and seeds characterized by harboring a specific transformation event particularly by the presence of the bar gene under control of a CaMV 35S promoter, at a specific location in the rice genome. The rice plants of the invention combine glufosinate tolerance with optimal overall agronomic performance, genetic stability and adaptability to different genetic backgrounds.

An input buffer interface circuit provides high state and low state input noise tolerance by a tri-state CMOS inverter having high state and low state inputs which are driven conditionally after the propagation of an input signal through predetermined high state and low state delay circuits. In one embodiment, a resettable high state delay circuits is provided by a cascaded combination of NOR gates and inverters, whereby the delay is preempted automatically by an excursion from high to low with ...

Fault tolerant computer system and method requiring reduced inter-unit communications. A primary system is arranged to execute event processes in response to received commands. Each time the execution of an event process is halted, due to normal termination or an interrupt, an event generator generates an event message indicating the type of event process and the reason or timing for halting the event process. The event message is used to instruct a backup system to execute the same event proces...

A Wind and Sun Tolerant Mesh is disclosed which is composed of either natural or synthetic material, the generally vertical directional strands crossed by horizontal strands, some or all of which individual horizontal strands of which broaden out on one side forming as sill which projects outward at an angle away from the plane surface of the mesh in a venetian blind profile, and wind baffling effect, while simultaneously allowing release of any excess pressure from wind gusting into the opposit...

A computer system includes memory modules, a central processing unit and a memory controller. The memory controller is configured to access the memory modules in response to interaction with the central processing unit and define a fault tolerant memory array with the memory modules. Each memory module stores first data represented by second data stored by the other memory modules.
