An apparatus and methods are provided for a suppressor to be coupled with a muzzle end of a barrel of a firearm to reduce muzzle blast and muzzle flash. The suppressor comprises a housing having a proximal end and a distal end. A front portion within the housing comprises a series of cylindrical gas expansion chambers for attenuating the temperature and energy of propellant gases accompanying a projectile fired from the firearm. An annular gas expansion chamber surrounds the cylindrical gas expansion chambers and directs a portion of the propellant gases from a rear portion of the suppressor to peripheral vents disposed at the distal end. Lateral chambers within the rear portion deflect and rebound a portion of the propellant gases before passing them into the annular gas expansion chamber. Ledges within the annular gas expansion chamber direct the propellant gases distally through suppressor toward the peripheral vents.

The present disclosure relates generally to hernia repair, and more specifically to forming a custom fitted mesh based on a topographical map of at least one portion of a patient's abdominal cavity. Some specific aspects of the present disclosure relate to exemplary methods, systems, devices and computer readable mediums for forming a custom fitted mesh based on a topographical map of the at least one portion of the patient's abdominal cavity.

A system automatically generates apparel collection imagery from user-provided imagery. The user-provided imagery includes images of people wearing one or more garments. The system uses segmenting analysis to analyze the user-provided image to identify locations of the garment. From the locations of the garments, the system can determine which garments from an apparel collection can be used to replace those in the user-provided imagery. The system uses pose estimation on the user-provided imagery and modifies a preview image of a replacement garment from the collection. This modified replacement garment image is used to replace the garment in the user-provided imagery.

A quotation system receives shape data of an article configured from a plurality of elements from a client terminal and provides quotation information of the article. The quotation system has: a memory storing the shape data and tolerance data in which multiple types of tolerance information relating to the elements are associated with each other; and a computer performing assistance processing to assist in setting of at least one type of the multiple types of tolerance information on the basis of the tolerance data.

A three-dimensional shape generation apparatus includes circuitry configured to perform one of a first processing or a second processing to generate three-dimensional shape information using point-group information indicating three-dimensional point groups as a generation processing based on an instruction operation received at an instruction reception screen, the instruction operation designating one of the first processing or the second processing. The circuitry performs all processes or a part of processes of the generation processing based on an operation input received at the instruction reception screen in response to the instruction operation designating the first processing. The circuitry performs all processes of the generation processing using a stored processing previously stored in a memory without using the operation input received at the instruction reception screen in response to the instruction operation designating the second processing.

A three-dimensional shape generation apparatus includes circuitry configured to generate three-dimensional shape information indicating a three-dimensional shape corresponding to a three-dimensional point group based on multiple sets of model shape information set by a model setting operation and point-group information indicating the three-dimensional point group. The model setting operation received at a reception screen sets the multiple sets of model shape information each indicating a three-dimensional model shape.
