System and method to remove artifacts from fingerprint sensor scans
A method and device for removing common artifacts, such as stiction, from fingerprint scans created by partial fingerprint scanners.

Spatial spreading in a multi-antenna communication system
Spatial spreading is performed in a multi-antenna system to randomize an “effective” channel observed by a receiving entity for each transmitted data symbol block. For a MIMO system, at a transmitting entity, data is processed (e.g., encoded, interleaved, and modulated) to obtain ND data symbol blocks to be transmitted in NM transmission spans, where ND≧1 and NM>1. The ND blocks are partitioned into NM data symbol subblocks, one subblock for each transmission span. A steering matrix is selected (e.g., in a deterministic or pseudo-random manner from among a set of L steering matrices, where L>1) for each subblock. Each data symbol subblock is spatially processed with the steering matrix selected for that subblock to obtain transmit symbols, which are further processed and transmitted via NT transmit antennas in one transmission span. The ND data symbol blocks are thus spatially processed with NM steering matrices and observe an ensemble of channels. |

Method for preventing overload in mobile telephone networks by using ‘always-on’ in the case of a call from a mobile telephone
A method for preventing overload in telecommunications networks with IMS by always-on for a call generated by a user, in which process the user makes a PDP Context request and a GGSN of said network provides a free IP address to him or her and the PDP Context becomes active. An S-CSCF of the network creates a record in which an association between the IP address and a characteristic identity of the IMS network is included. When the GGSN is going to deactivate the PDP Context for having been inactive for a preestablished time, an indication of such deactivation is sent to the IMS client which maintains the characteristic IMS identity-IP address association and marks it as fictitious. When the user generates a new call, the IMS client informs the UMTS terminal about the characteristic IMS identity-IP address association marked as fictitious, and the UMTS terminal sends a PDP Context request message, in which message the IP address of the IMS association is included. |

Image null-balance system with multisector-cell direction sensing
A light beam is detected/localized by multisector detector—quad-cell, or 5+ sectors handling plural beams.

One or more MEMS reflectors, and control system with programmed processor(s), sequence the spot toward center: following a normal to an intersector boundary; then along the boundary. One afocal optic amplifies MEMS deflections; another sends beams to imaging optics. After it's known which sector received a spot, and the beam shifts, source direction is reported. The system can respond toward that (or a related) direction. It can illuminate objects, generating beams reflectively. Optics define an FOR in which to search; other optics define an FOV (narrower), for imaging spots onto the detector. The FOR:FOV angular ratio is on order of ten—roughly 180:20°, or 120:10°. |

Auxiliary optics illuminate mirror back, monitoring return to measure (null-balance feedback) angle. To optimize imaging, auxiliary radiation propagates via splitters toward array (paralleling measurement paths), then focusing on imaging detector. Focal quality is developed as a PSF, optimized vs. angle; stored results later recover optima. Mirror drive uses magnet(s) on mirror(s). “Piston” motion yields in-phase wavefronts, so array dimensions set diffraction limit. Also: destructive reply; scaling optimizes acceleration vs. thickness; passive systems. |

Fallback mobile communication
Conventional video call attempts encountering a device inoperable according to a desired capability will fail if the receiving device is unable to complete the call at the desired service level (i.e. video).

The disclosed approach allows a call to complete at an alternate service level (i.e. voice instead of video) rather than failing the call completely, resulting in a source of lost revenue to the service provider (operator). |

Application of fluorescent protein to garden plant
The present invention provides a process for generation of a transformed plant capable of emitting fluorescence by introducing a gene encoding a non-plant-derived fluorescent protein into a plant such that the fluorescent protein is recombinantly expressed in the active form of its mature protein in the leaf or petal of the plant, and also provides a transformed garden plant capable of emitting fluorescence that is generated by using the process. For example, cDNA encoding the full-length amino acid sequence of a Chiridius poppei-derived fluorescent protein CpYGFP or its H52F modified protein CpYGFP H52F is inserted into a T-DNA-based expression vector system, which is in turn introduced into the chromosomal DNA of a plant. As a result, the transformed plant thus generated can exhibit fluorescence attributed to these fluorescent proteins and exhibit no substantial difference in the other phenotypes from wild-type one of the plant. |
