  • Camera device to capture and generate target lead and shooting technique data and images
    Patent number: 8908045
    Abstract: A novel system and process is described for the capturing of the images of a target, and/or the shooter, at the time around the discharge of a gun, bow, or shooting device and the display of the images prior to discharge, around point of discharge, and post discharge in a manner that allows the shooter to analyze the images and data. More particularly, the process is directed to shooting a moving target that must be led in order that the projectile (or projectiles) arrives on target after the point in time where the shoot decision is made and the projectile reaches the target area. This process aids the shooter by letting them see images and sight pictures of successful and unsuccessful shots and how much lead, if any, they had given the targets at the point in time they decided to shoot. It also allows for the shooters technique to be recorded and analyzed.

  • EXPLORATORY LINKTRACE OPERATIONS IN A COMPUTER NETWORK
    Publication number: 20140313940
    Abstract: In one embodiment, an exploratory linktrace is initiated from an initiating network device with an exploratory linktrace message (ELM) having a target address.

  • Methods and apparatuses to optimize updates in a file system based on birth time
    Patent number: 8849876
    Abstract: Methods and apparatuses that maintain birth time for a file system to optimize file update operations are described. The file system can include a plurality of snapshots or clones of data stored in one or more extents of blocks allocated in a storage device. Each extent may be associated with a time stamp according to the birth time. A request may be received from an executable using the file system to update data in a particular extent associated with a particular time stamp. In response, the current birth time in the file system and the particular time stamp may be compared to determine if the particular extent is not shared by more than one of the snapshots. If the particular time stamp is equal to the current birth time, the particular extent may be updated directly without performing an expensive operation to check whether a reference count of the particular extent is equal to one.
