Fast secure boot from embedded flash memory
A technique that reduces the startup time of a processing system authenticates a proxy for an image stored in tracked memory instead of authenticating the image stored in the tracked memory. A controller generates an alteration log authentication code based on an alteration log that is updated prior to programming the image stored in tracked memory. The controller records an alteration log authentication code in secure memory. The alteration log is indirectly related to a most recent image stored in the tracked memory. Authentication of the image of the alteration log is used as a proxy for authentication of the image stored in tracked memory, which is performed only when the tracked memory is modified. Use of the contents of the alteration log as a proxy for the contents of tracked memory accelerates the startup time of the system. |

Extended store forwarding for store misses without cache allocate
A load store unit (LSU) in a processor core detects that new data produced by the processor core is ready to be drained to an L2 cache.

Patio heater double dome infrared heat reflector/converter
A Patio Heater Double Dome Infrared Heat Reflector/Converter is disclosed. The patio heater dome attachment is attachable to a conventional patio heater so that the dome attachment covers the heater's heat shield, while maintaining an air gap therebetween. There are preferably standoff ridges or other features built into the dome attachment to maintain this air gap and to prevent air from flowing freely between the heat shield and the dome attachment. The dome attachment embodies a very low heat load so that very little heat conduction occurs between the heat shield and the dome attachment, such that more of the heater's energy is reflected towards the usage area. Finally, the perimeter edge of the dome attachment extends downwardly at least until it is essentially horizontally planar with the perimeter edge of the patio heater heat shield. |

Apparatus for heating fluids
The apparatus described herein uses a disc wafer-type rotor featuring channels disposed around its circumference and around the interior circumference of the rotor housing specifically to induce cavitation. The channels are shaped to control the size, oscillation, composition, duration, and implosion of the cavitation bubbles. The rotor is attached to a shaft which is driven by external power means. Fluid pumped into the device is subjected to the relative motion between the rotor and the device housing, and exits the device at increased temperature. The device is thermodynamically highly efficient, despite the structural and mechanical simplicity of the apparatus. Such devices accordingly provide efficient, simple, inexpensive, and reliable sources of distilled potable water for residential, commercial, and industrial use, as well as the separation and evaporation of other liquids. |
