Abstract: In various embodiments, apparatus and systems, as well as methods, may include an enhanced register to provide actuator signals to a memory array, the enhanced register including a first memory device including an first enable input, a first data input coupled to a register data input, and first memory device output, the first memory device output to couple to the memory array, and the enhances register to include a second memory device including a second enable input, a second data input coupled to the register data input, and a second memory device output, wherein the second memory device output provides a first output signal indicating when one or more of the actuator signals from the first memory device output are to be coupled to the register data input.
Abstract: A device has an annulus having a first end and a second end. A valve plate is coupled to the first end of the annulus by a fastener, wherein the valve plate is adapted to contact a valve seat on a hydrogen producing fuel cover. A diaphragm is coupled to the second end of the annulus by a fastener, wherein the annulus extends through a container for holding the hydrogen producing fuel and wherein the diaphragm moves the valve plate relative to the valve seat responsive to a different in pressure across the diaphragm.
