  • Patent number: 8112574
    Abstract: A flash controller has a flash interface accessing physical blocks of multi-level-cell (MLC) flash memory. An Extended Universal-Serial-Bus (EUSB) interface loads host commands into a command queue where writes are re-ordered and combined to reduce flash writes. A partial logical-to-physical L2P mapping table in a RAM has entries for only 1 of N sets of L2P mapping tables. The other N?1 sets are stored in flash memory and fetched into the RAM when a L2P table miss occurs. The RAM required for mapping is greatly reduced. A data buffer stores one page of host write data. Sector writes are merged using the data buffer. The data buffer is flushed to flash when a different page is written, while the partial logical-to-physical mapping table is flushed to flash when a L2P table miss occurs, when the host address is to a different one of the N sets of L2P mapping tables.

    Abstract: Vaporization chambers (distillation “pots”) are disclosed in which the liquid contained in such a pot is heated and circulated to establish thermal uniformity of the liquid and to route the circulated liquid past a thermally conductive member that contacts the liquid. The thermally conductive member extends from a location on a wall of the pot in a portion of the pot that holds the liquid as the liquid is being heated in the pot and conducts thermal energy directly from the liquid to a location outside the pot corresponding to the location on the wall. The pot desirably is divided into an upper portion and lower portion, wherein the liquid circulates from the lower portion to the upper portion and from the upper portion to the lower portion during heating. During this circulation, bubbles formed in the liquid can be routed into the upper portion in a manner resulting in fracture of the bubbles and recovery of liquid entrained in the bubbles, thereby preventing foam accumulation in the pot.

Dehydrated fluid is then collected and evacuated from the vacuum chamber. Vapor from the vacuum chamber, including the aqueous components of the fluid stream are collected, condensed and separately evacuated. The heating circuit limits surface temperature of a heating element in a closed-loop manner to avoid degradation of the fluid. The fluid stream is introduced into the vacuum chamber or is recirculated through the heating circuit to maintain a desired level of fluid temperature in a closed-loop manner.

  • Patent number: 6030504
    Abstract: A distiller control circuit includes a power bus with first and second lines and a fan circuit connected across the lines and having a fan motor and a fan thermostat in series. There is also a heater circuit connected across the lines and having a heater and a heater thermostat in series. The fan thermostat is normally open, closes at an elevated temperature and automatically re-opens when the temperature subsides. The heater thermostat is normally closed, opens at an elevated temperature and must be manually reset to the closed position.The raw water vessel has a reset mechanism with a pivot-mounted bar and a contact surface on the bar. When the contact surface is depressed, the bar is urged to the second position for resetting the heater thermostat. The heater circuit terminates in a two-stud male connector and the platform has a two-slot female connector. The studs slide into electrically-conductive engagement with the slots when the raw water vessel is inserted into the condensing platform.

  • Patent number: 5960031
    Abstract: An impulse radio communications system using one or more subcarriers to communicate information from an impulse radio transmitter to an impulse radio receiver. The impulse radio communication system is an ultrawide-band time domain system. The use of subcarriers provides impulse radio transmissions added channelization, smoothing and fidelity. Subcarriers of different frequencies or waveforms can be used to add channelization of impulse radio signals. Thus, an impulse radio link can communicate many independent channels simultaneously by employing different subcarriers for each channel. The impulse radio uses modulated subcarrier(s) for time positioning a periodic timing signal or a coded timing signal. Alternatively, the coded timing signal can be summed or mixed with the modulated subcarrier(s) and the resultant signal is used to time modulate the periodic timing signal. Direct digital modulation of data is another form of subcarrier modulation for impulse radio signals.

  • Patent number: 5833812
    Abstract: The water distiller 10 includes a plurality of housings 12, 14, 16 each mounted below a support plate 32. A voltage regulator 144 maintains a desired voltage potential between heating probes 34 and 36 within a heating bowl 46. An operator selector 142 automatically regulates the flow of water through inlet valve 70 to control the incoming water flow rate to the heating bowl. Area contact between water in the heating bowl and a substantially horizontal plate 42 at the lower end of each heating probe determines the electrical power used by the distiller, and maintains water in the heating bowl at substantially a constant level. An improved particle trap 80 and vent valve 100 provide reliable and safe operation of the distiller. Heating bowl 46 and a water inlet line 76 may be easily removed for cleaning the distiller.

    Abstract: A method and apparatus for separating water from a condensate mixture having two or more components drained from a compressed gas system is disclosed. The apparatus has a boiler with an inlet for receiving the condensate mixture and an outlet through which water vapor is removed. The boiler is maintained at sufficient negative pressure to lower the boiling point of the water in the condensate mixture and to enable the water in the boiler to boil at a lower temperature than if the negative pressure were not present. Heat is provided to the boiler to raise the temperature of the condensate mixture to equal or exceed that of the boiling point of the water in the negative pressure environment, but below the boiling point of the remaining components in the condensate mixture.
