Systems and methods are provided for enabling different ''bundling'' methods for downlink transmissions and provide different interpretations of the acknowledgement / negative- acknowledgement bit. A user equipment is configured so that it commonly acknowledges all downlink transmission time intervals within a bundle so that if one packet is determined to be erroneous, all packets in that bundle will be retransmitted. Additionally, the systems and methods are implemented by allowing an interpretation to be applied to the uplink acknowledgement / negative-acknowledgement field such that the user equipment is able to divide bundled downlink packets into smaller windows in Long Term Evolution (LTE) Release 8 time division duplex (TDD) mode. In LTE Advanced (LTE-A) TDD mode, various embodiments provide bundling within the time domain, within the frequency domain, and within a hybrid time- frequency domain. Furthermore, enhanced channel selection methods are also provided in support of the above-mentioned bundling methods in accordance with various embodiments.

A system and method for bundling long ferrous products comprises a roller table for delivering the products longitudinally to a receiving station. A cradle is spaced laterally from the receiving station and is constructed and arranged to receive and accumulate the products in bundle form. A stacker is positioned between the receiving station and the cradle, and a pre-stacker is positioned betweenthe stacker and the receiving station. A transport system laterally advances products from the receiving station to the pre-stacker, and the pre-stacker operates in concert with the transport system to pre-stack multiple layers of the products into sub-bundles and to transfer the sub-bundles to the stacker, which then operates to deposit the sub-bundles in the cradle.

The present invention relates to an active phase locking multi-optical fiber laser with no external phase modulation device and a coherent beam combination method. Two ends of an active optical fiberare written into a grating; the optical fiber with the maximum gain is used as a main resonant cavity for manufacturing optical fiber lasers; a plurality of active optical fibers with similar length are taken for manufacturing optical fiber lasers. Coating and outer cladding layers at two end parts of the optical fiber of each optical fiber laser are removed, and then a common outer cladding layeris arranged on the place where the outer cladding layers are removed. By utilizing synergistic coupling, the rest active optical fiber lasers are phase-locked on the laser of the main resonant cavitywithout adding any external phase modulation device, which simplifies the complex feedback control system of the prior active phase locking optical fiber laser. According to needs, the number of theoptical fiber lasers can be arbitrarily increased or decreased, so as to increase or decrease beam combination power. In an uncoupling area, the placement of the optical fibers can be arbitrarily arranged. The beam combination method can arbitrarily combine needed optical fiber lasers, can adopt discrete or united pumps, and is easy in heat dissipation and low in requirements on active optical fibers. The active phase locking multi-optical fiber laser is characterized in little influence from environment, compact structure, easy implementation, etc.

The port bundling method for distributed network exchange system includes the following steps: increasing one self-defined port field 'main port' to the port bundling list of network exchange system and marking the bundling group logically with the main port; substituting the source port of the up message from the sending port to the port bundling group with port expressed in the main port field and sending the substituted message to opposite end via the network plate of the network exchange system; and sending the responding message from the opposite end to the port expressed in the main port field. The method performs flux balance of port bundling via several data stream marking modes to realize the homogeneous distribution of flux and the back-up to various services. In addition, the two-layer translating in MAC learning to 'main port' mode can avoid the MAC learning address vibration problem effectively.

The invention discloses a bundle method and a device for a file to a host file. The host file comprises a plurality of bytes which are arrayed in a certain order and used for storing data. The device comprises a converting unit, a bundle unit and a modifying unit. According to the bundle method and the corresponding device for the file to the host file, a last byte of the host file is bundled with a file with an arbitrary length, so that the problems in the prior art that only small files can be bundled, and errors happen caused by the information on the head portion of the host file is too concentrated, large files which can be bundled with arbitrary lengths can be obtained, and the errors can not occur easily.

The invention provides an aerial triangulation free net building method based on a minimum spanning tree for special unmanned aerial vehicle images. For such special unmanned aerial vehicle images aswater falling, cloud shielding and overlapping holes, the problems of relative orientation, model connection failures and the like during conventional automatic aerial triangulation are solved; an aerial triangulation free net of the whole area is automatically built under the condition of not providing POS auxiliary data; exterior orientation elements of all images in a detected area and the initial values of object point coordinates are acquired; bundle-method block adjustment is performed; the exterior orientation elements of each image in the whole area and space coordinates of all objectpoints are wholly resolved. If a few of known control point coordinates are provided, the whole area can be incorporated into a control point ground coordinate system to realize absolute orientation.The processing level and the processing capability of the special unmanned aerial vehicle images are greatly improved.

The invention discloses a GPS / INS data direct orientation precision evaluation method, which takes photogrammetric emphasis equation collinearity equation as base and a multi-piece forward intersection of a bundle method as theory basis; the evaluation method is combined with the least square principle for obtaning the coordinate of a ground control point object by compensating calculation; and then a comparison with the actually measured coordinate of the ground control point is carried out for obtaining the error value of the coordinate by the statistics so as to evaluate the direct orientation precision of the outer orientation elements obtained by the GPS / INS system. The method has high evaluation precision and small measurement error, and the evaluation result can be used for manufacture practice directly, thus being capable of effectively avoiding the measurement error of the picpointed coordinate added in manual stereomeasurement; and the algorithm is not limited by image number.
