| 20100104210 | METHOD AND APPARATUS FOR SPATIO-TEMPORAL SUBBAND VIDEO ENHANCEMENT WITH SMALL TIME DELAY - Video processing method and means for enhancing a video stream, by computing transform coefficients using a spatio-temporal transform comprising a spatial subband transform and a causal time wavelet transform performing filterings with multiscale causal wavelets, modifying the transform coefficients with a nonlinear processing, and computing a processed video stream from the modified transform coefficients using a spatio-temporal reconstruction transform comprising an inverse subband transform and a short delay inverse time wavelet transform, where the short delay inverse time wavelet transform is implemented with wavelet filters modified with window functions to control the processing delay of the entire video processing method. | 04-29-2010 |
| 20100135400 | Processing Or Compressing N-dimensional Signals With Warped Wavelet Packets And Bandelets - A method and apparatus for processing or compressing an n-dimensional digital signal by constructing a sparse representation which takes advantage of the signal geometrical regularity. The invention comprises a warped wavelet packet transform which performs a cascade of warped subband filtering along warping grids of sampling points adapted to the signal geometry. It also comprises a bandeletisation which decorrelates the warped wavelet packet coefficients to produce a sparse representation. An inverse warped wavelet packet transform and an inverse bandeletisation reconstruct a signal from its bandelet representation. The invention comprises a compression system which quantizes and codes the bandelet representation, a decompression system, a restoration system which enhances a signal by filtering its bandelet representation, and a feature vector extraction system for pattern recognition applications of a bandelet representation. | 06-03-2010 |
| 20100220783 | FRAME BUFFER COMPRESSION FOR VIDEO PROCESSING DEVICES - For compressing a video signal, a local multiscale transform is applied to a frame of the video signal to obtain coefficient blocks. The coefficients of each block are distributed into a plurality of coefficient groups, and for at least one of the groups, a common exponent is determined for encoding the coefficients of the group, and respective mantissas are determined for quantizing the coefficients of the group in combination with the common exponent. Coding data including each exponent determined for a coefficient group and the mantissas quantizing the coefficients of the group in combination with this exponent are stored in an external frame buffer. | 09-02-2010 |

| 20110117789 | DEVICE FOR CONNECTING A SERVOMOTOR TO AT LEAST ONE ELECTRICAL CABLE - A device for connecting a servomotor to at least one electrical cable includes an external housing with at least one cable input, blocked by the cable in operation, and an opening closed by an electrical connection element and forming an interface with the servomotor. The electrical connection element includes a wall of an insulating material and elongate electrical contacts that extend through the wall in a direction substantially orthogonal to the wall, each electrical contact including an inner end inside the device for connection to an electrical cable, and outer end outside the device for being connecting to a corresponding electrical contact of the servomotor. The external housing includes an opening for draining fluid from inside the device in the operational configuration device, and the wall of the electrical connection element extends along a portion of the inner end of the electrical contacts. | 05-19-2011 |
| 20110120234 | METHOD FOR ASSESSING THE SEAL OF A SERVOMOTOR HOUSING - A method for assessing sealing of a housing of a servomotor. The method includes lowering the pressure inside the housing, from an initial pressure to a set pressure, by fluid suction through an opening in the housing, the opening being normally sealed by a plug. When the pressure inside the housing is equal to the set pressure, pressure variation inside the housing, for a predetermined time interval, is determined. The fluid suction prevents any fluid exchange with the housing in a direction opposite a fluid suction direction. The sealing of the housing of the servomotor is assessed based on the pressure variation determined. | 05-26-2011 |
| 20110121764 | SERVOMOTOR WITH REMOVABLE SUBUNITS - A servomotor includes a motor unit generating movement of a mechanical component, a position-detecting unit detecting the position of the mechanical component, and a control unit manually controlling the mechanical component. The manual control unit is inside a main enclosure, the manual control unit is actuated by an actuator located outside the main enclosure, and the main enclosure is connected to the motor unit and to the position-detecting unit, The position-detecting unit and the motor unit are located inside first and second enclosures that are distinct from the main enclosure and are removably connected to the main enclosure. The manual control unit can be actuated when the first and second enclosures are separated from the main enclosure. | 05-26-2011 |
