摘要： A system for providing virtual pan-tilt-zoom, PTZ, video functionality video to a plurality of users (60a-60c) over a data network (30) is provided. The system (100) comprises one or more network video cameras (10a-10e) positioned to make a video recording of a real-world target field (20), or a respective subarea thereof, and output a respective raw video segment onto the data network (30), a back-end camera calibration unit (42) which is adapted to obtain a relative position and orientation of the respective network video camera (10a-10e) with respect to a three dimensional world space for the target field (20), and to save the obtained relative position and orientation as metadata for the respective network video camera (10a-10e), a back-end video processing unit (44), connected to the data network (30) and adapted to receive the respective raw video segment(s) recorded by the network video camera(s) (10a-10e), and to store or buffer video contents of the respective raw video segment(s) in a back-end video storage (41), a back-end video streaming unit (46) adapted to stream the stored or buffered video contents and the saved metadata for the respective network video camera (10a-10e) onto the data network (30), a plurality of client devices (50a-50c) for use by the plurality of users (60a-60c). Each client device (50a-50c) is adapted to receive the streamed video contents and the metadata, determine a chosen virtual pan-tilt-zoom value and present, on a display (52a-52c) of the client device, the video contents by projecting directions, in the three dimensional world space, onto the display (52a-52c) based on the chosen virtual pan-tilt-zoom value and the metadata.

摘要： A device for machining a work piece creates an electrical potential between an electrode and the work piece or another conducting body proximate to the work piece. The electrical potential establishes an electrical field within the work piece that is expected to repel electrons and create a region of positively charged ions which repel one another. This region is expected to be weakened and material is expected to be removable from this region of the work piece using less force and energy than when machined by traditional machining techniques.

摘要： The present invention relates to an improved method and apparatus for image compression and particularly to an improved block coding apparatus and method for compression for use with the JPEG2000 standard, although not limited to this. Methods for coding and decoding blocks and subbands samples derived from still images video frames or related media, involving three bit-streams and the partitioning of samples from the blocking to define groups, is provided. A first bit-stream encodes the significance of whole groups. A second bit-stream encodes the significance of individual samples within each group. The second bit-stream also encodes an unsigned residual value for each significant group. A third bit stream provides a sign bit and any additional magnitude bits required to represent the significant sample values. Exponent predictors are computal using both exponent bounds and the additional magnitude bits associated with previous samples in the block.

摘要： The present application provides data transmitting and receiving methods in a narrow-band communication system, a two-way radio and a storage medium. The general idea of the present application is as follows: the two-way radio at the transmitting end firstly transmits a pilot signal, which activates the two-way radio at the receiving end into an operating state; the two-way radio at the transmitting end, after transmitting the pilot signal, transmits data to be transmitted to the two-way radio at the receiving end; the two-way radio at the receiving end, according to the pilot signal, switches the two-way radio at the receiving end into the operating state, and in its operating state receives data transmitted by the two-way radio at the transmitting end. This ensures that the two-way radio at the receiving end may receive data from the two-way radio at the transmitting end in real time, thereby improving the accuracy of data transmitted by the two-way radio at the transmitting end.

摘要： Systems and methods for processing debris from job sites are disclosed. Carts for receiving the debris are also disclosed. Each cart has a base, a plurality of wheels extending downwardly from the base relative to a vertical axis, and a plurality of walls extending upwardly from the base. The walls and the base of each cart cooperate to define a debris-receiving space. The carts can be engaged by a lifting apparatus that rotates along an arcuate path to position the carts in an unloading position.

摘要： A firearm using blowback action has a barrel which is movably mounted within a shroud which is fixedly mounted on the firearm's frame. A gas space is formed between the barrel and the shroud by a difference between the inner diameter of the shroud and the outer diameter of the barrel. At least one gas port provides fluid communication between the bore of the barrel and the gas space. During firing of a cartridge, pressurized gas in the gas space applies a force to the barrel which moves relatively to the shroud away from the muzzle end of the firearm to engage a slide or bolt, helping to move it out of battery and extract the spent cartridge casing. Gas is vented to the atmosphere through a gas vent defined between the barrel and the shroud in fluid communication with the gas space.

摘要： A support column extends in a longitudinal dimension and includes a plurality of outer hollow longitudinal structures. Each longitudinal structure defines an interior passage extending along a length of the longitudinal structure. The support column includes a plurality of inner members. The plurality of outer hollow longitudinal structures are aligned end-to-end along a single axis. The interior passages of the plurality of outer hollow longitudinal structures cooperate to define an interior passage of the support column. The inner members are aligned end-to-end along the single axis within the interior passage of the support column so that opposed longitudinal ends of each of the inner members extend to respective longitudinal ends of each adjacent inner member. At least one end of at least one inner member is longitudinally offset from every longitudinal end of the plurality of outer hollow longitudinal structures.
