20100308402 | 3D CHANNEL ARCHITECTURE FOR SEMICONDUCTOR DEVICES - Semiconductor devices and methods for making such devices that contain a 3D channel architecture are described. The 3D channel architecture is formed using a dual trench structure containing with a plurality of lower trenches extending in an x and y directional channels and separated by a mesa and an upper trench extending in a y direction and located in an upper portion of the substrate proximate a source region. Thus, smaller pillar trenches are formed within the main line-shaped trench. Such an architecture generates additional channel regions which are aligned substantially perpendicular to the conventional line-shaped channels. The channel regions, both conventional and perpendicular, are electrically connected by their corner and top regions to produce higher current flow in all three dimensions. With such a configuration, higher channel density, a stronger inversion layer, and a more uniform threshold distribution can be obtained for the semiconductor device. Other embodiments are described. | 12-09-2010 |

20150040948 | Vacuum Plate and Vacuum System - A vacuum plate converts a conventional wheelbarrow into a wet and dry dual purpose vacuum cleaner receptacle. Collection of fluids and solids directly into a wheelbarrow simplifies larger cleaning tasks, small flood remediation, transport of bulk particulate materials such as sand, pea stone, and mulch, and allows hydro-excavation to be carried out in home improvement and small scale professional landscaping projects. A fluid level sensor prevents the wheelbarrow from overflowing when collecting large quantities of fluid, and a sump pump allows fluids to be drained from collected slurries, leaving only solids in the wheelbarrow for reuse or independent disposal. | 02-12-2015 |

20090258718 | Billiards Shot Training Device and Method - The shot training device is used as a training aid for learning to play pocket billiards. The device aids the student in learning the three major components of a shot for pocket billiards: pocketing the object ball, cue ball direction, and cue ball speed control. The device includes an object ball circle for placement of an object ball. The device also includes an imaginary cue ball circle for aiming the cue ball. The device further includes cut angle lines and cue ball path lines for determining a cut angle to the object ball and plotting a path of the cue ball after impact with the object ball. A kit and a method of training a user to play billiards are also disclosed. | 10-15-2009 |
20120227176 | Wet Niche and Accessories for Vinyl and Sprayed Cement Pools - At least one socket in a swimming pool allows for the mounting of at least one pool accessory by way of a post mounted in the socket. In some embodiments, the socket is located in the bottom of the pool. In some embodiments, the socket is coupled to an electricity source to provide electricity to the post or pool accessory. In some embodiments, the socket is coupled to an air source to provide bubbles. In some embodiments, the socket is coupled to a fog source to provide a fog supply. In some embodiments, the socket is coupled to a water source to provide water flow to the post or pool accessory. In some embodiments, the fluid supplied to the post includes a scent. In some embodiments, the socket includes a light source and the post includes optical fibers to transmit light from the light source through the post. | 09-13-2012 |
