Title: Image projection system
Inventor: GIBBON MICHAEL A
IPC: G02B27/28
Filed: 1999-07-19
Abstract: An electronic projector has a projection system that includes a spatial light modulator (SLM) for imparting image information to the projected light beam. The light beam leaving the SLM is prepolarized in a defined orientation and the projected light is polarized in the same orientation so as to effectively block any light that has been scattered within the projector and become depolarized. The SLM may be a digital mirror device (DMD) or a liquid crystal device (LCD). Reflective surfaces within the projector may be covered or coated with material that polarizes the reflected light at an orientation orthogonal to the defined orientation.

Title: Method of and apparatus for controlling transmission power in a communication system
Inventor: TIEDEMANN EDWARD G JR
IPC: C08L23/10
Filed: 1998-04-16
Abstract: A forward link power control mechanism in a remote station (6) measures reverse link power control bits which are transmitted by one or more base stations (4a, 4b, 4n) on a forward traffic channel (10a). At the remote station (6) the reverse link power control bits from multiple base stations (4a, 4b, 4n) or multiple signal paths are measured, combined, and filtered to yield an improved measurement of the forward link signal quality. The reverse link (12a, 12b) power control bits which are deemed unreliable are omitted from use in the power control loop. The remote station (6) generates a set of forward link power control bits in accordance with the measurements and transmits these bits to all base stations (4a, 4b, 4n) in communication with the remote station (6). Each base station (4a, 4b, 4n) adjusts its gain of the forward traffic channel (10a) in accordance to its measurement of the forward link power control bit. The gains of the forward traffic channels (10a) of the base stations (4a, 4b, 4n) are corrected periodically so that erroneous reception of the forward link power control bits by the base stations do not accumulate.

Title: Method of making an absorbent member
Inventor: TANNER JAMES JAY
IPC: D04H1/70
Filed: 2000-03-21
Abstract: A method for making an absorbent member is disclosed. The method includes introducing fibers into an air stream to form an air-fiber mixture. This air-fiber mixture is then directed to a porous media having a first surface. The air-fiber mixture contacts the first surface and the fibers collect on the first surface and forms a fibrous mat. The air passes through the first surface and can be recovered and recycled, if desired. The air-fiber mixture is then terminated or diverted so that the fibrous mat can be removed from the first surface. The fibrous mat is wetted by water to obtain a desired moisture content.  Finally, the wetted fibrous mat is compressed to a predetermined thickness to form an absorbent member, which has unique expansion properties.
