Abstract: A system and method for improving stereoscopic images produced by a projecting device containing a single chip DMD, seen through an eye-switching device, such as a pair of liquid crystal (LC) shutter glasses. The system and method are used with a video projector used with a multiple-color, color switching device The color switching device produces Blue, Red and Green lights and at least one non-critical segment. A color sequencing firmware resident in the video projector is used to align a non-critical segment in front of the projector's main light source during the eye-switching device's unstable transition phase. If the non-critical segment is transmissive, the firmware controls the DMD so light is discontinued. If the non-critical segment is non-transmissive, light is physically blocked. If the non-critical segment is electronically defined, the firmware directly controls the DMD to discontinue the transmission of light for the duration of device's unstable transition phase.

Abstract: The invention is directed to a mobile communications system having improved spectral efficiency. The invention is further directed to methods and apparatus to achieve this improved spectral efficiency. In the mobile communications system communication with a plurality of mobile terminals is provided by a base station. Within the system terminals are adapted to communicate with one or more adjacent similar terminals to establish groups of terminals, called micro-cells. Each terminal within a micro-cell receives signals from the base station and then performs a first processing step on these signals. These processed signals are shared with all the other terminals within the micro-cell. Each terminal then performs a second processing step on the information it has received from all the other terminals within the micro-cell which enables it to derive a signal intended for reception by that terminal.

Abstract: A system and method for improving stereoscopic images produced by a projecting device containing a single chip DMD, seen through an eye-switching device, such as a pair of liquid crystal (LC) shutter glasses. The system and method are used with a video projector designed to be used with a multiple-color, color switching device, such as a color wheel. The color wheel includes at least three critical color segments. The color wheel may also physically include or be electronically re-defined to include at least one non-critical segment. A color sequencing firmware resident in the video projector is used to align a non-critical segment in front of the projector's main light source during the eye-switching device's unstable transition phase. If the non-critical segment is transmissive, the firmware controls the DMD so that light is discontinued. If the non-critical segment is non-transmissive, the light is physically blocked.

Abstract: Pre-drill pore pressure and fracture gradient predictions obtained from seismic velocity data are used in well design taking into account uncertainties in the velocity estimation and in the models that use the velocities to determine pore pressure. Using geological constraints, limits are established on hydrocarbon column height. It is also possible to predict the relative number of casings required to reach target reservoirs.

Abstract: A method and apparatus of imparting coverage gain to cell-edge or cusp mobile subscribers without resort to diluted frequency reuse factors is disclosed. Each base station adopts a priori a beam illumination sequence designed to minimize or obviate the likelihood of beam clashes in a narrow beam adaptive beamforming system. Such sequences may be optimized to impact primarily cell-edge subscribers or subscribers within cusp areas of adjoining beams or sectors. The inventive protocols may be applicable to fixed multibeam systems as well as individual steered beam and spatial null generation antenna systems.

Abstract: A wireless communications system supporting multiple MIMO transmission modes supporting both diversity and directional transmissions under a plurality of different transmission modes comprises a plurality of transmit and receive antenna elements where the transmit antenna elements are arranged to provide polarization diversity. The transmitting station derives actual knowledge of the forward channel by feeding back certain information such as a preferred beam index and a channel quality indicator figure of merit for that beam from the receiving station to the transmitting station along a reverse channel. The receiving station knows the beam weights used by the transmitting station. The transmitting station applies the fed back information to transmit user data intended for the receiving station in the optimal fashion, such as along the preferred beam and at a time when forward channel conditions are satisfactory.

Abstract: A radio system employing Orthogonal Frequency Division Multiplexed (OFDM) includes a Base Transceiver Station (BTS) along with a number of mobile terminals located within a coverage area of the BTS. In this system, a target mobile terminal is provided with a focused transmission beam to receive high data rate traffic information while the remainder of the mobile terminals are provided with pilot and signalling information. To achieve both objectives, a BTS is implemented with a transmission apparatus that generates a directional transmission beam for the data traffic information. In one design, this directional beam transmits the pilot and signalling information along with the data traffic information by rotating the beam within the coverage area. In another design, the BTS has a transmission apparatus that generates more than one transmission beam.

Abstract: Previous MIMO systems have used spatially diverse antenna elements in order not to reduce the number of orthogonal channels that can be realized. The present invention recognizes that this leads to large antenna sizes, as compared to multiple beam antenna systems which use closely spaced antenna elements. In order to provide a compact antenna unit, while still allowing a MIMO system to be exploited, the present invention recognizes that polarization diversity only can be used in a MIMO system without the need for spatially diverse antenna elements. Closely spaced antenna elements are used and this enables a compact MIMO antenna unit to be provided. In addition, such MIMO systems with polarization diversity but no spatial diversity can advantageously be used in line of sight situations and also combined with multi-beam antenna systems to further increase capacity.
