The method generates a compressed digital image from a original image. The compressed digital image allows random access to portions of the compressed image at a number of resolutions. The original image is first transformed (103) by a multi-level DWT to form a non redundant multiple resolution frequency domain representation of the image. The representation comprises a DC subband and a plurality of high frequency subbands arranged as levels, where each level represents a frequency contribution between adjacent resolutions and where each subband comprises a plurality of tiles. The DC subband is then entropy encoded (104) into the bitstream. The high frequency subbands are next entropy encoded (108,109, and 110) into the bitstream in level order (105,113,114) and tile order (107,111).

A technique for generating a demodulation ordering used in receive signal processing operations in a BLAST MIMO receiver that is based on a relative comparison of near-to-far resistance measures among vectors forming the estimated channel transfer function matrix is disclosed. This near-to-far resistance comparison provides a resulting demodulation ordering believed equivalent to that provided by conventional V-BLAST techniques without requiring computation of the pseudoinverse of the estimated channel matrix. Also disclosed is a successive interference cancellation technique which employs Multi-Staged Nested Weiner Filtering (MSNWF) to recover soft estimates of the transmitted component-symbols from the vector observed at the BLAST MIMO receiver. Employing such MSNWF estimation is believed advantageous in that it avoids the need for matrix inversion operations involving the estimated channel matrix, Covariance Level Order Recursive-MSNWF (MSNWF-COR) or MSNWF Conjugate Gradient techniques may be conveniently implemented to provide the desired MSNWF estimation.

The invention discloses an automatic leveling device and method for a forward moving type forklift truck. The automatic leveling device comprises a transmission mechanism, an angle sensor, a sloping oil cylinder and a controller. One end of the transmission mechanism is connected with a fork frame, and the other end of the transmission mechanism is connected with the angle sensor for transmission. The angle sensor is fixed to a side moving device assembly so as to output an electric signal in proportional relation with the rotating angle of the fork frame. The sloping oil cylinder is fixed to the side moving device assembly, and the pushing end face of the sloping oil cylinder faces the fork frame. The controller is connected with the angle sensor and the sloping oil cylinder and shields other sloping orders and controls the sloping oil cylinder to act when receiving the leveling order until the upper surface of a horizontal section of a fork rotates to the horizontal position. By means of the automatic leveling device and method for the forward moving type forklift truck, the closed-loop control principle is adopted, the electric signal output by the angle sensor serves as the negative feedback, the sloping angle of the fork is judged, the action of the sloping oil cylinder is controlled, and therefore the fork can be automatically horizontal. The control manner is simple, the work efficiency is improved, and the safety risk generated when the fork frame forks goods and retreats from a tray in the non-horizontal state is lowered.

A shape-based geometric database uses R-trees to compactly and efficiently represent design objects. Such R-trees may be populated in an efficient and balanced manner to improve the efficient use of such R-trees in various stages of circuit design, for example. For example, tiles are assigned to bins depending at least partially on orientation of the tiles and on proximity of the tiles to reference tracks having similar orientations. Bin R-trees may be defined, along with direction and layer R-trees using a level sequential process from lower levels to higher levels until a root node is defined in each case.
