Abstract: An improved hand held apparatus used for dusting, cleaning, polishing, and similar tasks utilizing a lightweight conventional power drill having a rotating axle with a chuck to which is attached one or more elongated extension members telescoped within one another and fixed relative to one another by a clamping connector, the first extension member having a first connecting member at one end constructed to be inserted into and attachable to the chuck and a second member at the opposing end of the extension members constructed to be attachable to the head of a conventional dusting device. The apparatus further includes a foam covered tubular hand guide member fitted about the first extension member and constructed to slide along the first extension member.

Abstract: An aerogel comprising an open-cell structured polymer matrix that includes a polyamic amide polymer is described.

Abstract: A method of making an aerogel is described. The method can include obtaining a solution comprising polyamic acid and an imidazole, adding a dehydrating agent to the solution in an amount where the molar ratio of the imidazole to the dehydrating agent is 0.17:1 to 2.8:1 and reacting the solution at room temperature to 100° C. to produce a polymer matrix gel comprising a polyamic amide, and drying the polymer matrix gel to form an aerogel comprising an open-cell structured polymer matrix that includes 5 wt. % to 50 wt. % of the polyamic amide based on the total weight of the polymer aerogel.

Abstract: The present invention generally relates to improvements in a Ashtray/Debowlers/ Tobacco/ Herb Grinder and more particularly to a aerospace Aluminum Lidded Ashtray/Debowler combine with Tobacco/Herb Grinder. There is a known ashtray/debowler in which has a bowl surface catchers the ashes and resin with a vertical spike mounted in the of the bottom middle of the ashtray. However, because such a conventional ashtray is only made with wood, glass or plastic, a aerospace aluminum ashtray will be the safest means, the latter is not safe and can cause fire hazards.

Abstract: Aerogel compositions that include polyamic amides, methods for preparing the aerogel compositions, and articles of manufacture that include or manufactured from the aerogel compositions are described.

Abstract: Provided herein are improved solid phase micro-extraction (SPME) devices, systems comprising such devices, and methods of use and manufacture thereof. In particular, SPME devices provided herein are configured to prevent damage (e.g., to the device and/or to a system in which they are employed) incurred, for example, through user error.

Abstract: Some embodiments include a method of operating a gaming system configured to present wagering game content for a wagering game. The method can include presenting, on a autostereoscopic display device of the gaming system, the wagering game content in two-dimensional form without stereoscopic depth. The method can also include detecting a game condition of the wagering game other than a location of a player of the wagering game. The method can also include determining a degree of stereoscopic three-dimensional depth based on the game condition. The method can also include presenting, via the autostereoscopic display device of the gaming system, the wagering game content with the degree of stereoscopic three-dimensional depth.

Abstract: This document describes techniques for processing graphics in wagering game systems. Some embodiments of the inventive subject matter use stereoscopic 3-D graphics and 2-D graphics to present composite images including multiple views of a virtual 3-D wagering game environment. Such embodiments present the composite images on stereoscopic 3-D devices.

Abstract: A wagering game system and its operations can include presenting wagering game content for a casino wagering game to have a two-dimensional appearance via an autostereoscopic display device. The operations can further include detecting an indication to change a presentation of the two-dimensional appearance without stereoscopic depth to have a stereoscopic three-dimensional appearance having stereoscopic depth. The operations can further include detecting a game condition for the casino wagering game, determining a degree of stereoscopic three-dimensional depth to use for the wagering game content based on a value for the game condition, and changing the presentation of the two-dimensional appearance to the stereoscopic three-dimensional appearance in response to determining the degree of the stereoscopic three-dimensional depth to use.

Abstract: A grille-step assembly mounted on a vehicle includes a vehicle having a vehicle frame and a grille-step assembly secured to the frame. The grille-step assembly includes a grille frame secured to the vehicle frame. The grille frame has opposed grille brackets with at least one bar connecting the opposed grille brackets to one another and a step assembly. The step assembly includes opposed step brackets having a bottom crossbar and a step crossbar that connect the opposed step brackets to one another. The assembly is releasably mounted so that in a closed position both the bottom crossbar and the step crossbar are positioned between the opposed grille brackets, and in an open position one of the bottom crossbar and step crossbar is positioned away from the opposed grille brackets.
