Abstract: A method of detecting a workpiece jam condition in a pneumatic tool includes striking a workpiece by a blade of the tool, detecting whether a piston to which the blade is attached reaches a predetermined position within a predetermined time, and determining a workpiece jam condition has occurred if the piston does not reach the predetermined position within the predetermined time.

Abstract: Disclosed are techniques for compressing data of an image using multiple processing cores. The techniques include obtaining, using a first (second, etc.) processing core, a first (second, etc.) plurality of reconstructed blocks approximating source pixels of a first (second, etc.) portion of an image and filtering, using the first processing core, the first plurality of reconstructed blocks.

Abstract: A fastener tool which contains a motor, a drive mechanism connected to the motor and adapted to drive a piston, and a locking module. The locking module includes a rotating member coupled with the drive mechanism and adapted to rotate with a spindle and define a rotation axis; and a receiving member adapted to engage with the rotating member at and engaging portion. The rotating member includes a latch and a biasing member, wherein the biasing member moveably supports the latch in a direction substantially perpendicular to the rotation axis. Therefore, the locking module provides a locking mechanism that prevents back driving of the fastener tool that increases the lifespan and efficiency of the tool.

Abstract: Disclosed are techniques for compressing data of an image. Intermediate pixels may be determined. Each location of the image may be associated with a block of a plurality of blocks of a first size and a block of a plurality of blocks of a second size. For each block of the first size and of the second size, a first cost for a first mode and a second cost for a second mode may be determined in parallel using the intermediate pixels. A final mode and a final block size may be selected for each location of the image using the first cost and the second cost for each of a respective block of the first size and a respective block of the second size associated with a corresponding location. Final pixels may be determined, and a representation of the image may be obtained based on the final pixels.

Abstract: Disclosed are apparatuses, systems, and techniques that may perform methods of pyramid optical flow processing with efficient identification and handling of object boundary pixels. In pyramid optical flow, motion vectors for pixels of image layers having a coarse resolution may be used as hints for identification of motion vectors for pixels of image layers having a higher resolution. Pixels that are located near apparent boundaries between foreground and background objects may receive multiple hints from lower-resolution image layers, for more accurate identification of matching pixels across different image levels of the pyramid.

Abstract: A more efficient method of data collecting using multicast instead of individual slave-by-slave requests for data defines a multicast address through a master station. Slave stations are divided into feature groups according to their feature value and a mapping relationship table between the multicast addresses and the feature groups is established. Data request frames from the master station to the slave stations include a destination address which is parsed by all the slave stations, and if the destination address is the same as the multicast address in the mapping relationship table, the slave stations in the feature group associated with the destination address transmit data in response to the master station, the data request being discarded by other slave stations which are not associated.
