Abstract: Provided are a Random Access (RA) configuration method and apparatus, an RA method and apparatus, a base station, User Equipment (UE) and a computer-readable storage medium. The RA configuration method may include: grouping multiple Synchronization Signal Blocks (SSBs) and selecting a primary SSB from each SSB group; sending UE indication information indicating a primary SSB to be sent in an SSB group to be sent; sending at most one SSB in each SSB group to be sent to the UE; and sending the number of SSBs corresponding to preambles in each RA Channel (RACH) Occasion (RO) and the number of ROs under Frequency Division Multiplexing (FDM) to the UE.

Abstract: An example high pressure ice-breaking machine with a double row of wheels comprises: a frame, a plurality of wheels, and a plurality of spring mechanisms. The plurality of wheels comprises: a front ice-breaking wheel group and a rear ice-breaking wheel group. The plurality of wheels include a total of two rows of wheels, which include a front ice-breaking wheel group and a rear ice-breaking wheel group. The plurality of wheels are positioned horizontally under the frame. The front ice-breaking wheel group and the rear ice-breaking wheel group include a same number of wheels. The two rows of wheels are staggered in double rows from front to back. A first ice-breaking wheel from the front ice-breaking wheel group and a second ice-breaking wheel from the rear ice-breaking wheel group form a staggered wheel pair, and the first ice-breaking wheel and the first ice-breaking wheel are hinged to a same spring mechanism.

Abstract: A roadway clearing device includes a plurality of rotatable members for dislodging material (snow or ice) from a roadway and a conveyer disposed rearward of the rotatable members to collect and laterally discharge material from the roadway. The device may include a plurality of shovel members disposed rearward of the conveyor to divert material from the roadway to the conveyor for lateral discharge. The rotatable members and/or shovel members may be disposed for separate movement from corresponding downward positions to upward positions relative to an interconnected support frame. Spring-loaded, extensible members may be provided to bias the rotatable members and/or shovel members to their corresponding downward positions.

Abstract: The present interactive recording and playback technique provides the ability to archive the content, the discussions and the metadata of a meeting or similar event; then aggregate, search and annotate across this data; and finally edit, combine, or split various recordings to create new presentations. This interactive recording and playback technique provides rich productivity and innovation that is unavailable today.

Abstract: A method and system for cropping an image is provided. The cropping system automatically crops an image by selecting an image template whose condition is best satisfied by the image and then by selecting a cropping of the image that best attains the goal of the selected image template. The cropping system may use a metric or objective function to rate how well a cropping attains the goal of the selected image template. The cropping system may apply various optimization algorithms to identify a cropping that is the best as indicated by the metric. The cropping system can then automatically crop the image based on the identified cropping.
