Abstract: An active matrix liquid crystal display cell (20) for AC operation including a first field effect transistor switch (22) for switching video information to a first storage capacitor (24) and a second field effect transistor switch (62) for switching the voltage of the first storage capacitor (24) to one side of a liquid crystal cell (20). The second transistor (62) is connected to be switched on by a common signal, for example, a vertical sync signal, and the top plate voltage applied to the liquid crystal cell (20) is alternated in synchronism with the common signal, resulting in a doubling of the effective potential applied across the liquid crystal cell (20).

Abstract: An improved LCMOS display device employing a silicon-on-insulator (SOI) substrate (41) having an epitaxial silicon layer (15) lying over an implant-generated dielectric layer (13). MOS device and capacitor elements (17, 19, 21) used to activate the display are formed and interconnected in the epitaxial silicon (15). The implant-generated dielectric layer (13) and underlying silicon substrate (41) also serve as capacitor elements, thereby simplifying the structure and fabrication of the display device and providing improved operation through improved isolation of the MOS device elements formed in the epitaxial silicon (15) from the substrate (41).

Abstract: A self-tuning optical notch filter is employed to separate coherent from noncoherent radiation in an overall beam. The presence of coherent radiation is detected, preferably with an interferometer, and the frequency of the detected coherent radiation is determined. An electrical control signal is generated with a frequency corresponding to that of the coherent radiation, and causes an optical filter to filter out the coherent radiation from the beam. In the preferred embodiment the optical filter is a Bragg cell, and the electrical control signal is applied to an electro-acoustic transducer which furnishes an acoustic control signal to the Bragg cell.

Abstract: A wide dispersion baffle for a vertically oriented loudspeaker includes a first semi-conical reflective section that is concave toward the speaker and has a semicircular rim positioned at the periphery of the speaker. It extends at an angle of about 45° to the radiation axis of the speaker to its apex on the speaker axis. A second semi-conical reflective section is convex toward the speaker and extends from the apex of the first semi-conical section at substantially the same 45° angle with respect to the speaker radiation axis. Sound emanating from the vertically directed speaker is reflected by both the concave and convex semi-conical reflector sections in a pattern centered about a substantially horizontal plane, but the sound is reflected through widely diverging angles in such horizontal plane. Baffle arrangements can provide horizontal dispersion patterns of any angular width between about 180° and 360°.

Abstract: The present invention provides improvements to an array processor for analyzing two dimensional arrays of spatially related data elements. More specifically, provision is made to permit a cellular array processor (10) to efficiently perform data dependent processing such as floating point arithmetic functions. In the preferred embodiment, one module (84) in the array processor (12) generates a signal applied to bus line (24) when all of the bits in a register (86) are zero. The signal on bus line (24) effects the shifting operation of a shift register (36) in a memory module (34) located on a different functional plane. Thus, the processing functions carried out in each elemental processor (26) can be made to depend on the value of data stored therein instead of being dictated solely by a simultaneous executed instruction from the control processor (14) as is the normal case.

Abstract: An adaptive noise cancellation system reduces undesired noise in a closed loop control system by injecting an adaptively constructed noise cancellation signal at an appropriate point in the closed control loop. The generation of a compensation filter N for adaptive noise cancellation loop error signal is disclosed by two methods. A first method is an inverse error rejection response (IERR) method. A second method optimally matches spectrums of a noise signal and a noise reference signal at the adaptive noise cancellation system. This second method is referred to as a spectral matching (SM) method.

Abstract: An electrode for a transverse gas flow laser has a simplified profile which facilitates the fabrication and subsequent alignment of the electrodes within a laser cavity. Each electrode (10) is essentially comprised of an upper horizontally planar surface (12) having a surrounding radiused edge (14) of a given radius of curvature which is terminated by a surrounding vertical side wall (20). The termination of the radiused edge by the side wall acts to reduce the total electrode width, resulting in a reduction in required laser package size. A bottom surface (16) of the electrode may be provided with a mounting means (18), such as a plurality of tapped openings for bolting the electrode to an inner surface of the laser package.

Abstract: A receiver for multiple groups of modes comprising a beam splitter (21) for receiving an incoming optical signal from a graded index rod (19). The incoming optical signal includes low mode groups (33) and high mode groups (31). The beam splitter (21) transmits a transmitted portion of the incoming signal toward a graded index rod (23) and reflects a reflected portion of the incoming signal to a detector (27). The graded index rod (23) substantially separates the low mode group (33) from the high mode group (31) in the transmitted portion of the signal and provides a separated signal in the form of the low mode group (33) to a detector (25).
