Title: Method and apparatus to produce potable water
Inventor: PAUTZ RICHARD S
IPC: C02F1/04
Filed: 2005-12-09
Abstract: A method and apparatus for producing potable water from non-potable water, in which a supply of air is passed through a heating unit to increase the air temperature and then passed through an evaporative cooling media through which the non-potable water is passed in liquid/gas contact with the heated air. The temperature of the air leaving the evaporative media is reduced as a result of contact with the water, and its moisture content is increased. The cooler moist air is then passed through a cooling coil to cause the moisture in the air to condense as liquid water, which is then collected and made suitable for use as drinking water.

Title: Methods for receiving and transmitting signals in a multicarrier system
Inventor: LAROIA RAJIV
IPC: H04B7/04
Filed: 2006-03-08
Abstract: Base stations transmit strip signals using strip signal segments and self supporting modulation scheme techniques facilitating rapid channel estimate. A strip segment occupies one OFDM symbol time interval and uses a set of downlink tones; some, e.g., half, of the tones are left unused facilitating SIR measurement. The strip segments are advantageously timed to correspond to uplink access intervals in which connected wireless terminals do not typically transmit uplink signals. Connected wireless terminals including: multiple antennas used in combination, an antenna duplex module, single RF receiver chain and single RF transmitter chain, switch antenna coefficient combinations based on strip signal segment timing. The wireless terminal determines an independent downlink channel quality measurement, e.g., SNR and/or SIR for each strip signal segment and for on-going non-strip signaling. The wireless terminal compares channel quality measurements and selects an antenna coefficient combination to be used during non-strip signaling intervals obtaining very good antenna gain.

Title: Silicon single crystal growing method, silicon wafer and soi substrate using such silicon wafer
Inventor: ONO TOSHIAKI
IPC: H01L21/02
Filed: 2005-09-14
Abstract: In a silicon single crystal growing method, a silicon single crystal is manufactured by CZ method, at a hydrogen partial pressure of 40Pa or more but not more than 400Pa, in an inert atmosphere in a growing apparatus, by growing a single crystal straight body section as a nondefective region where no grown-in defect exists. Therefore, a wafer wherein the entire plane is composed of the nondefective region having no grown-in defect and BMD is sufficiently and uniformly formed can be easily provided. Such wafer can be widely used since generation of characteristically nonconforming integrated circuits formed on the wafer can be greatly reduced and that the wafer can contribute to improvement of the manufacturing yield as a substrate meeting the demands of circuit microminiaturization and density increase.
