20150037137 | Gas Transfer Vacuum Pump - An improved vacuum pump mechanism is described in which an intersecting solid or perforated element is arranged to intersect a channel member. Relative movement of the intersecting solid or perforated element and channel member causes gas molecules to be urged from inlet to an outlet of the pump. Gas molecules are constrained within the channel member and interaction of the gas molecules with the flat and smooth surfaces of the intersecting solid or perforated member influence momentum of the gas molecules so that they are directed towards the outlet. In one embodiment, the channel member is formed as a helix and the intersecting solid or perforated elements are disk-shaped. An alternative embodiment is provided having the channel member configured as a spiral and the perforated elements as cylindrical skirts. The pump provides significant improvements in pump capacity, reduced power consumption and size of pump. | 02-05-2015 |

20120141669 | APPARATUS AND METHOD FOR IMPROVED RECOVERY OF LATENT FINGERPRINTS - Hydrating an object bearing a latent fingerprint and then selectively drying the object leaving the fingerprint hydrated. The hydrated fingerprint is then coated with cyanoacrylate ester, preferably in a heat accelerated cyanoacrylate ester vacuum chamber. Hydrating is preferably accomplished by chilling the object below a dew point and then exposing the object to humidified air to condense a thin uniform layer of water over the object and latent fingerprint. Drying is preferably done with a vacuum. After drying reaches the preferred state, the CE is heated and coats the condensation-hydrated latent fingerprint. Preferably, the method is implemented in an automated system using one computer-controlled chamber for chilling, condensing, vacuum drying, and CE coating the latent fingerprint. The operator simply puts the object in the chamber, initiates the process by computer, and is prompted by the computer to remove the recovered latent print. Prints unrecoverable by prior art means are recovered. | 06-07-2012 |

20140089862 | DESTINATION ROUTING IN A VIRTUAL WORLD - A user input requesting a route that satisfies particular criteria (e.g., a route to one or more destinations) in a virtual world is received. A route from the current location of the user in the virtual world that satisfies the criteria is determined, and an indication of this route is displayed to the user. The indication of the route is displayed in a gameplay mode in which the user can immerse himself or herself in the virtual world. The indication of the route can be a multi-purpose indication, such as additionally indicating where it is recommended that the user accelerate or brake in a racing game. The user input can be received while the user is in the gameplay mode, allowing the user to remain immersed in the virtual world while requesting the route. | 03-27-2014 |
